2018

• Statement 1 is incorrect. The first Lok Sabha sat from 1952 to 1957 and the largest opposition party in it was the Communist Party of India with sixteen seats. The Swatantra Party was founded by C. Rajagopalachari only in 1959, so it could not have existed in the first Lok Sabha at all. This is a pure date check and is the cleanest entry point into the question.
• Statement 2 is correct. Ram Subhag Singh of the Congress (O) was accorded recognition as Leader of the Opposition in the Lok Sabha in 1969, the first time the office was formally recognised; statutory recognition with salary and allowances followed under the Salary and Allowances of Leaders of Opposition in Parliament Act, 1977.
• Statement 3 is incorrect. The threshold applied by the Speaker under the Mavalankar convention and the Directions by the Speaker is one tenth of the total strength of the House, that is 55 members in a House of 545, not 75. The 1977 Act itself prescribes no numerical floor and speaks only of the leader of the largest opposition party recognised as such by the Speaker. Elimination route: recognising that Swatantra postdates the first Lok Sabha kills options (a) and (d) at once, leaving (b) and (c), and the well known 55 rather than 75 figure then settles it on statement 3.

Hence (b).

All three are standard xerophytic adaptations and all three reduce transpirational water loss.

• Statement 1 is correct: a thickened cuticle and waxy coating raise the diffusive resistance of the leaf surface, and hard sclerophyllous tissue resists wilting at low water potential.
• Statement 2 is correct: reducing leaf area reduces the total transpiring surface, and small leaves also shed sensible heat more efficiently, so leaf temperature and hence the leaf to air vapour pressure difference stay lower.
• Statement 3 is correct: in Opuntia and many Acacia and Euphorbia species the leaf is reduced to a spine and photosynthesis shifts to the stem, which is the most extreme form of the same strategy. Since no statement can be rejected, only option (d) survives. The governing principle is that transpiration scales with the product of surface area and the conductance of that surface, so a desert plant can economise on either factor or on both.

Hence (d).

• Statement 1 is correct. The 70th Round reported Rajasthan with the highest share of agricultural households among rural households in the major States, at roughly 78 per cent, reflecting the near universality of some landholding in rural Rajasthan even where holdings are arid and low yielding.
• Statement 2 is incorrect. Other Backward Classes accounted for about 45 per cent of agricultural households, not a little over 60 per cent. The 60 per cent figure is a plausible sounding inflation of a real number and is the trap in the question.
• Statement 3 is correct. Kerala was the outlier State in which about 61 per cent of agricultural households reported their maximum income from non agricultural sources, consistent with Kerala's high non farm rural employment, remittance dependence and very small average holding size. Elimination route: statement 2 is the only one a prepared candidate is likely to be able to reject outright, since the OBC share of agricultural households is quoted in most survey summaries at around 45 per cent; rejecting it removes (a), (b) and (d) in one step and leaves (c). Hence (c). Without that single figure there is no route at all, which is what makes this difficult.

• Statement 1 is incorrect. The National Green Tribunal was indeed established by statute, the National Green Tribunal Act, 2010, but the second half of the statement fails: the Central Pollution Control Board is also a statutory body, constituted under section 3 of the Water (Prevention and Control of Pollution) Act, 1974, and later entrusted with further functions under the Air (Prevention and Control of Pollution) Act, 1981. It is not a creature of executive order.
• Statement 2 is correct and is close to the language of the statutes themselves. The NGT Act recites the effective and expeditious disposal of environmental cases as its object, and the Tribunal's existence relieves the High Courts and the Supreme Court of writ litigation on environmental matters. The functions of the CPCB under section 16 of the Water Act include promoting the cleanliness of streams and wells, and under the Air Act it is charged with improving the quality of air. Governing principle: almost every major Indian pollution and environment regulator is statutory, so a claim that any of them rests on an executive order should be treated as suspect on sight. That single instinct settles the question, since rejecting statement 1 leaves only (b) and (d), and statement 2 is a faithful paraphrase of the parent Acts.

Hence (b).

• Statement 1 is correct. Parliament can place a law in the Ninth Schedule, and does so by exercising its constituent power under Article 368, that is by a constitutional amendment adding an entry to the Schedule. The Ninth Schedule was itself inserted by the First Amendment in 1951 together with Article 31B, which grants the listed laws immunity from challenge on the ground of inconsistency with any Fundamental Right.
• Statement 2 is incorrect, and it is incorrect twice over. First, the immunity conferred by Article 31B is confined to Part III; it was never an immunity from all judicial examination, so a Ninth Schedule law can still be challenged on grounds such as legislative competence. Second, and decisively, in I. R. Coelho v. State of Tamil Nadu (2007) the Supreme Court held that laws placed in the Schedule after 24 April 1973, the date of Kesavananda Bharati, are open to judicial review on the touchstone of the basic structure. The absolute bar asserted in statement 2 therefore does not exist. Elimination route: statement 1 is uncontroversial for anyone who knows the First Amendment, which removes (b) and (d); the choice between (a) and (c) then turns entirely on whether Coelho is known. Hence (a). This is settled law from 2007 and is not a case of the key decaying.

• Option (c) is correct and is the textbook definition. The Merchant Discount Rate is the fee a merchant pays to the acquiring bank, expressed as a percentage of transaction value, for the service of accepting a card payment; it is shared out among the acquirer, the issuing bank as interchange and the card network as a switching fee. The word discount in the name refers to the fact that the merchant is credited the transaction value less this deduction.
• Options (a) and (d) are wrong because they invert the direction of the payment, turning a charge borne by the merchant into an incentive received by the merchant, from a bank and from the Government respectively.
• Option (b) is wrong because it describes cashback or a reward payment to the cardholder, which is a customer acquisition expense and unrelated to the merchant side of the transaction. Governing principle: a rate is a charge on someone, and the name identifies who bears it; three of the four options make the merchant a recipient rather than a payer, so they fail on the structure of the term alone.

Hence (c).

• Statement 2 is plainly incorrect and is the eliminating statement. The Nuclear Suppliers Group is an informal export control arrangement operating by consensus through published guidelines; it is not a treaty and has no power to enrol anyone in the Non Proliferation Treaty, which is a separate multilateral instrument joined by deposit of an instrument of accession. France is the standing counter example, having participated in the NSG from its founding in the mid 1970s while acceding to the NPT only in 1992. Rejecting statement 2 removes options (b) and (c) immediately and reduces the question to (a) against (d).
• Statement 1 is treated as correct by the key, on the reasoning that membership brings a country inside the trading arrangement through which sensitive nuclear material, equipment and technology are supplied, so that transfers otherwise barred by the guidelines become available. On that reading the answer is (a).

Hence (a).

• Statement 1 is incorrect. The equalisation levy was enacted by Chapter VIII of the Finance Act, 2016 as a standalone charge and was deliberately kept outside the Income Tax Act, 1961. The design was not accidental: had it been an income tax, it would have been subject to the residence and permanent establishment rules of India's tax treaties, and a non resident advertising platform with no permanent establishment in India could not have been taxed at all.
• Statement 2 is incorrect, and it is incorrect as a direct consequence of statement 1 being incorrect. Double Taxation Avoidance Agreements relieve double taxation of income taxes covered by the treaty. Because the equalisation levy is not an income tax and is not a tax covered by the treaties, the non resident cannot ordinarily claim foreign tax credit for it in the home jurisdiction, which was the principal criticism of the levy from the affected companies and from the United States. Both statements failing, the answer is (d). Governing principle worth teaching: the levy sits outside the Income Tax Act precisely so that it sits outside the treaty network, so statements 1 and 2 stand or fall together and a candidate who sees the link needs only one of the two facts.

Hence (d).

• Statement 1 is correct. The FRBM Review Committee under N. K. Singh recommended a debt to GDP ceiling of 60 per cent for the general government by 2022 to 2023, split as 40 per cent for the Centre and 20 per cent for the States, and treated that ratio rather than the fiscal deficit as the primary anchor of fiscal policy.
• Statement 2 is incorrect and is the eliminating statement, because the two figures have been transposed. The Centre carries domestic liabilities of roughly 49 per cent of GDP and the States roughly 21 per cent. The internal logic of statement 1 exposes the error without any recall of the actual numbers: if the Committee proposed a 40 to 20 split between Centre and States, the existing burden cannot plausibly be 21 for the Centre against 49 for the States.
• Statement 3 is correct. Article 293(3) provides that a State may not raise a loan without the consent of the Government of India so long as any part of a loan made to it by the Centre, or in respect of which the Centre has given a guarantee, remains outstanding. Elimination route: rejecting statement 2 removes (b) and (d), and statement 1 being accepted removes nothing further, so the answer rests on statement 3, which is standard constitutional text.

Hence (c).

• Statement 1 is correct. India meets close to two thirds of its edible oil consumption from imports, principally palm oil from Indonesia and Malaysia and soya and sunflower oil from Latin America and the Black Sea, so imported quantity has exceeded domestic production for well over five years. The structural reason is that oilseeds in India are overwhelmingly rainfed and low yielding, and the oilseed area lost ground to cereals under the assured procurement of wheat and rice.
• Statement 2 is incorrect. Edible oils attract customs duty, and far from there being a nil rate, duties were being raised repeatedly in the period immediately before this paper, with crude palm oil and refined palm oil rates moved up in stages during 2017 and 2018 to shield domestic growers. Elimination route: the word all combined with the absolute claim of no duty whatever should be treated as a warning sign, and any candidate who followed the duty increases of 2017 to 2018 rejects statement 2 outright, which leaves (a) and (d); the import dependence in statement 1 is standard economic survey material.

Hence (a).

• Option (c) is correct. Lala Lajpat Rai wrote biographical works on Mazzini, Garibaldi, Shivaji and Shri Krishna, was deported to Mandalay in 1907, spent the years from 1914 to 1920 abroad, chiefly in the United States, where he founded the Indian Home Rule League of America and the journal Young India, and was elected to the Central Legislative Assembly in 1926. Every clause of the stem therefore fits him.
• Option (a) fails on the American residence and on the Assembly: Aurobindo Ghosh withdrew to Pondicherry in 1910 and never sat in a legislature.
• Option (b) fails because Bipin Chandra Pal's foreign sojourn was in England, not America, and he is not associated with this set of biographies.
• Option (d) fails because Motilal Nehru, though certainly a member of the Central Legislative Assembly and its Opposition leader, was a constitutional lawyer and Swarajist and wrote no such biographies. Elimination route: the American residence is the sharpest discriminator, since it removes Aurobindo and Pal in one stroke, and the choice of European nationalist subjects, Mazzini and Garibaldi, points to the Extremist rather than the Liberal constitutionalist tradition, which removes Motilal Nehru.

Hence (c).

• Statement 1 is incorrect on the express words of the statute. Section 9 of the Aadhaar (Targeted Delivery of Financial and Other Subsidies, Benefits and Services) Act, 2016 provides that an Aadhaar number or authentication shall not by itself confer any right of or be proof of citizenship or domicile. The reason is structural rather than incidental: Aadhaar is issued to residents, defined by a period of stay in India, and residence is a different legal category from citizenship, so the number could never evidence the latter.
• Statement 2 is also incorrect. The Unique Identification Authority of India can deactivate or omit an Aadhaar number, and the Aadhaar (Enrolment and Update) Regulations, 2016 expressly provide for omission and deactivation, for instance where the enrolment is found to be based on false biometric or demographic information or where a duplicate is detected. Both statements failing, the answer is (d). Governing principle: statement 2 asserts an absolute and irreversible administrative act, and absolute claims of that kind are almost always false in a regulatory framework that must be able to correct its own errors.

Hence (d).

• Statement 1 is correct. The Aral Sea is the standard textbook case of anthropogenic desiccation. Soviet era diversion of the Amu Darya and Syr Darya for cotton irrigation from the 1960s onward cut off the inflow to an endorheic basin, and with evaporation continuing unchecked the lake lost the great majority of its area and volume and split into separate remnant water bodies, leaving the salt and pesticide laden Aralkum desert behind.
• Statement 2 is incorrect. The Black Sea is a large marine basin connected to the Mediterranean through the Bosporus and Dardanelles and fed by the Danube, Dnieper and Don; it has serious pollution and anoxia problems in its deep water, but it has not shrunk or dried up.
• Statement 3 is incorrect. Lake Baikal is the deepest and most voluminous freshwater lake on Earth, holding roughly a fifth of the world's unfrozen surface fresh water; it faces pollution and species pressure but no desiccation. Elimination route: the governing distinction is hydrological, between a closed basin with no outlet, where any diversion of inflow translates directly into loss of area, and an open or connected basin, where it does not. Only the Aral Sea is endorheic among the three, so only statement 1 can be correct and (a) follows without any need for further recall.

Hence (a).

• Option (d) is correct. The Rule of Law Index is published annually by the World Justice Project, an independent non profit organisation, and scores countries on eight factors including constraints on government powers, absence of corruption, open government, fundamental rights, order and security, regulatory enforcement, civil justice and criminal justice, using household and expert surveys rather than official statistics.
• Option (a) is wrong: Amnesty International produces country reports and campaigns on specific human rights violations and publishes no such composite index.
• Option (b) is wrong on institutional character rather than on subject matter, and this is the most instructive elimination in the question: the International Court of Justice is the principal judicial organ of the United Nations, deciding contentious cases between States and giving advisory opinions, and a court does not rank the countries appearing before it.
• Option (c) is wrong on two counts, since the correct title is the Office of the United Nations High Commissioner for Human Rights, and that Office issues thematic and country reports and services the treaty bodies rather than publishing an index of this kind. Governing principle: composite governance indices are overwhelmingly the work of private research bodies and think tanks rather than of intergovernmental organs, since the latter cannot easily rank their own members.

Hence (d).

• Option (c) is correct. The National Financial Switch, which interconnects the ATM networks of banks in India and makes interoperable cash withdrawal possible, is owned and operated by the National Payments Corporation of India. NPCI took the switch over from the Institute for Development and Research in Banking Technology in 2009 and also runs RuPay, UPI, IMPS, NACH and the Bharat Bill Payment System.
• Option (a) is wrong because the Indian Banks' Association is an industry representative body that frames common positions and model practices; it operates no payment infrastructure.
• Option (b) is wrong because the National Securities Depository Limited holds securities in dematerialised form for the capital market and has nothing to do with retail cash withdrawal.
• Option (d) is the strongest distractor and is wrong on the distinction between regulating and operating: the Reserve Bank of India authorises and supervises payment systems under the Payment and Settlement Systems Act, 2007, and it promoted NPCI along with the banks, but it does not itself run the ATM switch. Governing principle: in Indian retail payments the regulator and the operator are deliberately separated, and NPCI is the umbrella operator.

Hence (c).

• Statement 1 is correct as a description, if loosely worded. The Capital Adequacy Ratio, or Capital to Risk Weighted Assets Ratio, is the ratio of a bank's own capital, Tier 1 and Tier 2, to its risk weighted assets, and its purpose is exactly what the statement says: capital contributed by shareholders and retained from profits stands as the first buffer against credit losses, so that depositors are not exposed when borrowers default. The statement describes the amount rather than the ratio, which is imprecise, but the function is correctly stated.
• Statement 2 is incorrect. The minimum Capital Adequacy Ratio is prescribed by the regulator, not chosen by the bank. The Reserve Bank of India stipulates a minimum of 9 per cent of risk weighted assets, above the Basel III floor of 8 per cent, together with capital conservation and countercyclical buffers and an additional requirement for domestic systemically important banks. A bank may hold more than the minimum but cannot set the minimum. Elimination route: prudential floors are by definition regulatory, since a rule each bank set for itself would provide no protection at all, so statement 2 collapses on its own logic and (a) follows.

Hence (a).

• Statement 1 is correct. An open Application Programming Interface is a published contract, in this case an HTTPS and XML based one, that any application can call provided it conforms to the specification and is routed through an authorised Authentication User Agency. Because the interface is defined at the level of the network protocol rather than of a particular operating system or handset, it can be embedded in a point of sale terminal, a micro ATM, a mobile handset, a tablet or a kiosk, which is precisely what open means here.
• Statement 2 is correct. The Aadhaar authentication specification supports fingerprint, iris and one time password modalities, and iris authentication was available through registered iris devices well before this paper, having been introduced partly because iris performs better than fingerprint for manual labourers and the elderly whose ridge patterns are worn. Both statements being correct, the answer is (c). Governing principle: an open API is a contract, not a product, so the natural implication of openness is device and vendor independence, and the modalities supported are a separate question of specification, not of openness.

Hence (c).

• Option (d) is correct. Famine was formally declared in parts of Unity State in South Sudan in February 2017, the first such declaration anywhere in six years, driven by civil war, displacement from farmland and the collapse of markets. In Yemen the war from 2015 onward, together with restrictions on the ports of Hodeidah and Saleef and the destruction of the currency and the salary system, produced what the United Nations repeatedly described as the world's largest humanitarian crisis, with millions in acute food insecurity.
• Option (a) is wrong: Angola and Zambia had drought and economic stress in this period but no conflict driven famine of this scale.
• Option (b) is wrong: Morocco and Tunisia are middle income North African States with no famine and no relevant armed conflict.
• Option (c) is the strongest distractor, since Venezuela's economic collapse did produce severe malnutrition and mass emigration into Colombia, but the cause was hyperinflation and policy failure rather than war or ethnic conflict, and Colombia was the receiving country rather than an affected one. Governing principle: the stem specifies famine caused by war or ethnic conflict, so the discriminator is the presence of active armed conflict, which narrows the field to Yemen and South Sudan at once.

Hence (d).

• Statement 1 is correct. Wood's Despatch of 1854, often called the Magna Carta of English education in India, introduced the grants in aid system, under which private and missionary schools that satisfied prescribed standards of secular instruction and inspection received public funds. This was the origin of the aided school in India and of the enduring pattern of state funded but privately managed education.
• Statement 2 is correct. The Despatch recommended universities on the model of London University, and the universities of Calcutta, Bombay and Madras were established in 1857 as examining bodies in consequence.
• Statement 3 is incorrect and is the discriminating statement. The Despatch did not prescribe English at all levels; it laid down a graded medium, with the vernaculars to be used for mass and primary education and English reserved for higher education, on the express reasoning that European knowledge could reach the mass of the people only through their own languages. Elimination route: statement 3 contains the absolute at all levels, and knowing that Wood's Despatch is the document that rehabilitated vernacular instruction after the Anglicist ascendancy of 1835 is enough to reject it, which removes (b), (c) and (d) together.

Hence (a).

• Option (b) is correct. The Committee on Subordinate Legislation exists precisely to police delegated legislation, examining whether rules, regulations, sub rules, by laws and orders framed under a statute or under the Constitution stay within the authority delegated, and reporting to the House where they exceed it, impose retrospective effect without authority, or have not been laid before the House as required.
• Option (a) is wrong: the Committee on Government Assurances tracks promises, undertakings and assurances given by Ministers on the floor and reports on the extent to which they have been carried out, which is scrutiny of executive follow through rather than of rule making power.
• Option (c) is wrong: the Rules Committee considers amendments to the House's own Rules of Procedure and Conduct of Business, so it is directed inward at the legislature and not at the executive.
• Option (d) is wrong: the Business Advisory Committee allots time to government business and recommends the timetable of the House. Governing principle: the stem describes the classic function of legislative oversight of delegated legislation, and the name of the committee states that function directly, so the question turns on distinguishing the four committees by object, with subordinate legislation being the only one directed at rule making power.

Hence (b).

• Statement 1 is incorrect. Section 23(1) of the Right of Children to Free and Compulsory Education Act, 2009 provides that the minimum qualifications for a teacher shall be those laid down by an academic authority authorised by the Central Government, and that authority is the National Council for Teacher Education, not a State Council of Teacher Education. The design is deliberate, since a nationally uniform floor was the point; States may relax only in the manner the Act permits.
• Statement 2 is correct. Under the qualifications notified by the National Council for Teacher Education pursuant to section 23, a candidate for the primary stage must pass the Teacher Eligibility Test conducted by the appropriate Government in accordance with NCTE guidelines, in addition to holding the prescribed academic and professional qualification.
• Statement 3 is incorrect. The great majority of teacher education institutions in India are privately managed and self financing, a pattern the Justice Verma Commission examined critically; institutions directly under State Governments are a small minority, nowhere near 90 per cent. Elimination route: statements 1 and 3 both make sweeping attributions to State Governments, and the whole architecture of the Act runs the other way, towards a central academic authority; rejecting either one leaves only (b) and (d), and rejecting both settles it.

Hence (b).

• Pair 1 is correctly matched. Chapchar Kut is the spring festival of the Mizos, celebrated in March after the clearing of the jhum plots and before sowing, and is the best known festival of Mizoram.
• Pair 2 is correctly matched. Khongjom Parba is a Manipuri ballad form, a narrative sung to the dholak that commemorates the battle of Khongjom of 1891 between the Manipuri forces and the British, and it grew into a distinct performance genre.
• Pair 3 is incorrectly matched. Thang Ta, from thang for sword and ta for spear, is the martial art of Manipur, performed in ritual and stage forms; it is not from Sikkim. Elimination sequence matters here. Recognising that Thang Ta belongs to Manipur removes options (c) and (d), which leaves (a) and (b), and the question then turns entirely on whether Khongjom Parba is placed in Manipur.
• Pair 2 is therefore the decisive pair, and a candidate who knows only that Thang Ta is Manipuri cannot get past two options. Hence (b). Useful pattern: this item packs three different genres, a festival, a ballad and a martial dance, into one set, and two of the three belong to Manipur, so the examiner is testing whether the candidate over generalises from the single Sikkim distractor.

• Statement 1 is correct. The Food Safety and Standards Act, 2006 consolidated a scattered body of food law and repealed the Prevention of Food Adulteration Act, 1954 along with several commodity specific orders covering fruit products, milk and milk products, meat, vegetable oil products and solvent extracted oil. The shift was one of approach as well as of statute: from detecting adulteration after the fact to setting science based standards and licensing food businesses.
• Statement 2 is incorrect. The Food Safety and Standards Authority of India is a statutory body created by section 4 of the same Act, headed by a Chairperson of the rank of Secretary to the Government of India and run by a Chief Executive Officer. It functions under the administrative aegis of the Ministry of Health and Family Welfare but is not placed under the Director General of Health Services, who heads a separate technical directorate. Elimination route: the object of creating a statutory authority with its own Chairperson and Board is to give it a measure of independence from the departmental hierarchy, so subordinating it to a directorate official would defeat the design; that reasoning rejects statement 2 without recall of the organogram, leaving (a) and (d), and statement 1 is standard.

Hence (a).

• Option (b) is correct. The two state solution is the framework for resolving the Israeli Palestinian conflict by establishing an independent State of Palestine alongside Israel, broadly on the pre 1967 lines with agreed land swaps, and it is the position embodied in the Oslo Accords and in successive United Nations resolutions.
• Option (a) is wrong: the disputes involving China, whether across the Taiwan Strait or in Tibet and Xinjiang, are framed by Beijing as one country questions, and the vocabulary used there is one China and one country two systems, which is the opposite formula.
• Option (c) is wrong: Iraq's internal question is Kurdish autonomy within a federal Iraq, and the September 2017 Kurdistan referendum was about secession, not about a two state partition of the kind meant here.
• Option (d) is wrong: Yemen's war is between the internationally recognised government and the Houthi movement, with a southern secessionist strand, and it is discussed in terms of federal or unitary arrangements rather than as a two state solution. Governing principle: the phrase is a term of art attached to one conflict, and the elimination turns on noticing that the other three conflicts are all argued in the language of unity or autonomy rather than of partition into two States.

Hence (b).

• Statement 1 is incorrect. The National Food Security Act, 2013 abandoned the below poverty line and above poverty line classification as the basis of entitlement. It covers up to 75 per cent of the rural and 50 per cent of the urban population, divided into Antyodaya Anna Yojana households and priority households, with the identification of priority households left to the States within centrally determined coverage ratios. Confining eligibility to below poverty line families would describe the earlier targeted public distribution system, not the Act.
• Statement 2 is correct. Section 13 provides that for the purpose of issue of ration cards the eldest woman in the household, not being less than eighteen years of age, shall be the head of the household, and that where no such woman is available the eldest male member acts until she attains that age.
• Statement 3 is incorrect on the figure. Schedule II prescribes a take home ration of not less than 600 calories per day, with 18 to 20 grammes of protein, for pregnant women and lactating mothers during pregnancy and for six months after childbirth, along with maternity benefit of not less than six thousand rupees. The 1600 figure is roughly the daily requirement of an adult and is far above any supplementary ration, which is the tell. Elimination route: statement 2 is the single most quoted provision of the Act and can be accepted with confidence, which removes (c) and (d); the choice between (a) and (b) then rests on the below poverty line claim in statement 1, and the whole point of the Act was to move away from that classification.

Hence (b).

• Option (d) is correct. Geographical indications are one of the seven categories of intellectual property covered by the Agreement on Trade Related Aspects of Intellectual Property Rights, which is Annexure 1C to the Marrakesh Agreement establishing the World Trade Organization. Articles 22 to 24 of TRIPS require members to provide legal means for interested parties to prevent misleading use of a geographical indication and to prevent unfair competition, with additional protection for wines and spirits. India, having had no sui generis law on the subject, enacted the 1999 Act and brought it into force in 2003 to discharge that obligation, the Darjeeling tea case having demonstrated how exposed Indian producers were without one.
• Option (a) is wrong because the International Labour Organization sets labour standards through conventions and recommendations and has no intellectual property mandate.
• Option (b) is wrong because the International Monetary Fund deals with exchange rates, balance of payments financing and macroeconomic surveillance.
• Option (c) is wrong and is the most instructive distractor, since the United Nations Conference on Trade and Development does work extensively on trade and development and on technology transfer, but it is a deliberative and research body that produces analysis and consensus texts, not binding obligations that require domestic legislation. Governing principle: only the World Trade Organization among the four generates treaty obligations enforceable through dispute settlement, and after 1995 nearly every Indian intellectual property statute or amendment traces to TRIPS.

Hence (d).

• Statement 1 is incorrect and it is the decisive statement. The Mines and Minerals (Development and Regulation) Amendment Act, 2015 replaced the discretionary first come first served regime with compulsory auction, and it vested the conduct of those auctions for major minerals other than coal, lignite and atomic minerals in the State Governments, the Centre retaining only the power to prescribe the terms and the auction rules. State Governments therefore do have the power to auction non coal mines, and coal is the exception rather than the rule.
• Statement 2 is incorrect. Both States carry gold occurrences: Andhra Pradesh has the Ramagiri gold field in Anantapur district, and Jharkhand has gold in the Subarnarekha placer deposits and in the Singhbhum belt.
• Statement 3 is correct. Rajasthan has iron ore, notably at Morija Banol in Jaipur district and Nathra ki Pal and Dalli in the Udaipur region, though these are minor deposits beside the Odisha and Chhattisgarh reserves. Elimination sequence matters. Accepting statement 3 removes options (a) and (b); rejecting statement 2 removes the same two options and nothing further. Only rejecting statement 1 separates the two survivors, (c) and (d), so a candidate must know the 2015 auction reform in addition to one of the two mineral facts.

Hence (d).

• Statement 1 is correct. BHIM is a front end to the Unified Payments Interface, so a payment can be pushed to any account held with a bank that is live on UPI, addressed either by a virtual payment address, by Aadhaar number, or by account number with IFSC. Interoperability across banks is the whole design intent of UPI, which sits on the Immediate Payment Service rails.
• Statement 2 is incorrect, and the numbers in it are inverted as well as wrong. A chip and PIN debit card carries two factors, the card itself as something the holder has and the PIN as something the holder knows. BHIM carries three: the registered handset with its SIM binding, the device or application password, and the UPI PIN. So the card has fewer factors than BHIM, not more, and neither figure in the statement is right. Elimination route: statement 1 is uncontroversial and removes options (b) and (d), after which the candidate need only notice that the classic two factor example in every textbook is precisely the card and PIN pair to reject the claim of four. Hence (a). The teaching point is that authentication factors are counted by category, something you have, something you know and something you are, and not by the number of steps in the user interface.

• Option (a) is correct. Convention 138 of 1973 is the Minimum Age Convention, which obliges ratifying States to fix a minimum age for admission to employment not below the age of completion of compulsory schooling and in no case below fifteen, with a transitional floor of fourteen for developing economies. Convention 182 of 1999 is the Worst Forms of Child Labour Convention, which requires immediate and effective measures to eliminate slavery, trafficking, debt bondage, forced recruitment of children into armed conflict, commercial sexual exploitation, illicit activity and hazardous work. Both belong to the ILO's set of eight fundamental conventions, and India ratified the pair in June 2017 after amending the Child Labour (Prohibition and Regulation) Act in 2016 to align domestic law.
• Options (b) and (c) are wrong on mandate rather than on detail, and that is the useful elimination: climate adaptation in agriculture belongs to the UNFCCC and FAO domain, and food price regulation and food security to the FAO and the World Food Programme, neither being within the competence of a labour standards body.
• Option (d) is the strongest distractor because the ILO does have conventions on gender parity, but those are Convention 100 on equal remuneration and Convention 111 on discrimination in employment, not 138 and 182. Governing principle: identify the issuing organisation's mandate first, which disposes of two options, then recall that the child labour pair is the one India ratified most recently.

Hence (a).

The question is one of negative framing, so the task is to find the single statement that departs from Article 110(1).

• Option (a) reproduces clause (a) of Article 110(1), the imposition, abolition, remission, alteration or regulation of any tax, and is correct.
• Option (b) reproduces clause (c), the custody of the Consolidated Fund or the Contingency Fund of India and the payment of moneys into or the withdrawal of moneys from any such Fund, and is correct.
• Option (d) reproduces clause (b), the regulation of the borrowing of money or the giving of any guarantee by the Government of India, and is correct.
• Option (c) is the statement that is not correct, and it fails on one word. Clause (d) of Article 110(1) speaks of the appropriation of moneys out of the Consolidated Fund of India, not out of the Contingency Fund. The distinction is not pedantic but structural: the Consolidated Fund can be drawn upon only by appropriation made by law, which is exactly why appropriation from it is a Money Bill matter, whereas the Contingency Fund is placed at the disposal of the President for unforeseen expenditure and is drawn upon by executive authorisation, with parliamentary approval sought afterwards to recoup the Fund. Appropriation out of the Contingency Fund therefore is not and cannot be the subject of a Money Bill. Notice that the Contingency Fund appears legitimately in option (b), in connection with custody and with payments into and withdrawals from the Fund, which is what makes option (c) hard to spot.

Hence (c).

• Statement 1 is correct. Under Article 55, the value of the vote of a member of a State Legislative Assembly is obtained by dividing the population of the State by the total number of elected members of its Assembly and then dividing the quotient by one thousand. Since the population per constituency differs greatly across States, the value differs across States as well, from over two hundred for Uttar Pradesh down to single figures for Sikkim. The population used is still that of the 1971 census, frozen by the Forty second Amendment and continued by the Eighty fourth Amendment until the first census after 2026.
• Statement 2 is incorrect. The value of the vote of every elected member of Parliament is identical, whether the member sits in the Lok Sabha or in the Rajya Sabha, because it is derived from a single calculation: the total value of the votes of all MLAs of all States divided by the total number of elected members of both Houses. The figure was 708 for the elections held from 1997 onward and fell to 700 after the Jammu and Kashmir Assembly ceased to exist. The design point is that parity between the two Houses is deliberate, since the President is elected by a single electoral college in which the Union is represented as a whole and not chamber by chamber. Elimination route: statement 1 is standard, which removes (b) and (d), and the single well known number 708 applying to all MPs settles the rest. Note also that nominated members of either House and members of Legislative Councils do not vote at all.

Hence (a).

• Option (a) is the answer the key takes and it is correct in substance. The entire logic of India's post 2005 nuclear arrangements is a separation of the civilian from the strategic programme: designated civilian facilities are offered for safeguards while the military programme stays outside, and it is this bifurcation that made international nuclear commerce possible for a State outside the Non Proliferation Treaty.
• Option (b) is wrong precisely because it inverts that bargain; no instrument brings India's military nuclear installations under IAEA inspection, and had any done so the arrangement would have been politically impossible.
• Option (c) is wrong because uranium purchase rests on the clean waiver granted by the Nuclear Suppliers Group in September 2008 and on the bilateral agreements concluded afterwards with the United States, France, Russia, Kazakhstan, Canada and Australia; safeguards are a precondition for those transactions rather than the source of the entitlement, and the Group is in any event a set of guidelines rather than a seller.
• Option (d) is wrong for the same reason as statement 2 of question 7 in this paper: no safeguards instrument confers membership of the Nuclear Suppliers Group, which is decided by consensus among its participating governments and has repeatedly been withheld from India.

Hence (a).

• Option (c) is correct. As of the date of this paper ASEAN had free trade agreements in force with six partners: Australia and New Zealand jointly, China, India, Japan and the Republic of Korea. Of the countries listed, Australia, China, India and Japan therefore qualify, which is exactly the set in option (c). Canada and the United States do not, and both are wrong for the same reason: neither has ever concluded a free trade agreement with ASEAN as a bloc, the American approach having run through the Trans Pacific Partnership with selected ASEAN members and through bilateral arrangements such as the Singapore agreement.
• Option (a) fails on Canada, option (b) fails on the United States, and option (d) fails on both. The elimination is unusually clean, because every wrong option contains at least one North American country and the correct option contains neither. Governing principle worth carrying: ASEAN's free trade partners are precisely the six non ASEAN participants in the Regional Comprehensive Economic Partnership negotiations, so a candidate who remembers the RCEP membership of sixteen, being the ten ASEAN States plus these six, can reconstruct the list without separate recall.

Hence (c).

• Statement 1 is incorrect on both the place and the year. The Global Alliance for Climate Smart Agriculture was launched at the United Nations Climate Summit convened by the Secretary General in New York in September 2014, more than a year before the Paris conference of December 2015. The distractor works because candidates associate every climate initiative of the period with Paris.
• Statement 2 is correct. GACSA is a voluntary, multi stakeholder alliance with no negotiated instrument behind it, so joining creates no legally binding obligation on a member; it functions as a knowledge and investment platform organised around productivity, resilience and mitigation.
• Statement 3 is incorrect. India did not join GACSA and was not instrumental in its creation, having been reluctant about the climate smart agriculture framing on the ground that it risked importing mitigation expectations into the agriculture of developing countries, where the priority is adaptation and food security. Elimination route: statement 2 is a safe accept even for a candidate who has never heard of the alliance, because a voluntary alliance by definition binds nobody, and rejecting the Paris attribution in statement 1 then removes options (a) and (d), leaving (b) against (c) to be settled by India's non membership.

Hence (b).

• Statement 1 is incorrect. Digital India is built on nine pillars, among them broadband highways, universal access to mobile connectivity, the public internet access programme, e governance, e Kranti, information for all, electronics manufacturing, information technology for jobs and early harvest programmes. Creating domestic substitutes for foreign internet companies on the Chinese model is not among them; the Chinese pattern rests on excluding foreign platforms from the market, which India has never adopted as policy.
• Statement 2 is incorrect. Compulsory or encouraged domestic location of data centres, that is data localisation, formed no part of the Digital India design.
• Statement 3 is correct and is the least ambitious sounding of the three, which is the trap: BharatNet aims to connect gram panchayats with optical fibre, and the public internet access programme provides for common service centres and Wi Fi in schools, public places and tourist centres. Elimination route: statement 1 can be rejected on the model it invokes, since Digital India nowhere adopts a Chinese style closed internet, and once (a) and (d) fall the choice reduces to whether data localisation was an aim, which it was not.

Hence (b).

• Pair 1 is correctly matched. Aleppo is Syria's largest city and its industrial and commercial centre, and the battle for it from 2012 to 2016 was the defining engagement of the Syrian civil war.
• Pair 2 is incorrectly matched. Kirkuk is in northern Iraq, the centre of a major oil field and a disputed city claimed by both Baghdad and the Kurdistan Regional Government; federal forces took control of it in October 2017 after the Kurdish independence referendum.
• Pair 3 is incorrectly matched. Mosul is Iraq's second city, on the Tigris, held by the Islamic State from 2014 and recaptured after a nine month campaign that ended in July 2017.
• Pair 4 is correctly matched. Mazar i Sharif is the principal city of northern Afghanistan and the seat of the shrine attributed to Ali. Only pairs 1 and 4 are correct, so the answer is (b). The elimination is quick and does not require all four facts. Kirkuk and Mosul are both Iraqi, and once either is recognised as such, options (a), (c) and (d) each contain a wrong pair and fall away, leaving only (b). Governing principle: the examiner has deliberately displaced two Iraqi cities into Yemen and Palestine, so a candidate who has the Iraq theatre clear in mind needs nothing else.

Hence (b).

• Option (b) is correct. The Government of India Act, 1935 divided legislative power into three lists, Federal, Provincial and Concurrent, and vested the residuary power, that is the power to legislate on matters not enumerated in any of the three lists, in the Governor General, who could authorise either the Federal or a Provincial legislature to enact such a law.
• Options (a) and (c) are wrong because the residuary power was withheld from both legislatures precisely so that it should not accrue to elected Indian representatives at either level.
• Option (d) is wrong because Provincial Governors, though armed with special responsibilities and with the power to act against ministerial advice, had no share in residuary legislative competence. The comparative point is the one worth teaching. In Canada residuary power lies with the Centre and in the United States and Australia with the States, and the framers of the Indian Constitution followed the Canadian model by placing it with the Union in Entry 97 of the Union List with Article 248. The 1935 Act did neither: it gave the power to the Crown's representative rather than to any legislature, which is the sharpest single illustration that the 1935 federation was a federation without responsible government at the apex.

Hence (b).

• Statement 1 is correct. Article 179(a) provides that the Speaker of a Legislative Assembly shall vacate office if he ceases to be a member of the Assembly, subject to the proviso discussed below. The office is derivative of membership, so loss of membership through resignation, disqualification or the setting aside of an election ends the office.
• Statement 2 is incorrect. The proviso to Article 179 is explicit: the Speaker shall not vacate office upon a dissolution of the Assembly until immediately before the first meeting of the Assembly after the dissolution. The reason is institutional continuity. Some presiding authority must exist to authenticate records, deal with the business of the outgoing House and, in the case of the Lok Sabha, be available should the House be summoned; a gap between dissolution and the first sitting of the new House would leave the office vacant for weeks. The identical rule applies to the Speaker of the Lok Sabha under Article 94. Elimination route: statement 1 is the general rule and statement 2 is the exception stated as though it were the rule, and the candidate has to recognise that dissolution is the one case in which the Speaker survives the House. Note the contrast with the Chairman of the Legislative Council and with the Vice President as Chairman of the Rajya Sabha, since a Council and the Rajya Sabha are permanent bodies not subject to dissolution at all.

Hence (a).

• Option (b) is correct and expresses the settled position of liberal political theory that law is the condition of liberty rather than its antagonist. In the absence of law there is no security of person or property, and what remains is not liberty but the arbitrary freedom of the strongest, since one person's unrestrained licence is another's subjection. Law creates the sphere within which liberty can be exercised, which is the sense in which Locke argued that the end of law is to preserve and enlarge freedom, and Hobbes that outside a common power there is no liberty worth having.
• Option (a) states the crude negative liberty position, that liberty is simply the absence of restraint and therefore diminishes with every additional law. This is rejected because it cannot distinguish between a law that restrains and a law that enables, such as a law creating contractual remedies or protecting against assault.
• Option (c) is about the source of legitimate authority, that is popular sovereignty and consent, which is a separate question from the relationship between law and liberty; a law made by the people may still be oppressive and a law not so made may still protect.
• Option (d) makes a narrower point about legal certainty, and while frequent change does erode predictability, it describes a defect in legislation rather than the relationship in principle. Governing principle: the examiner is testing whether the candidate can separate the concept of liberty from the concept of absence of restraint.

Hence (b).

• Statement 1 is correct. Article 361(2) provides that no criminal proceedings whatsoever shall be instituted or continued against the President or the Governor of a State in any court during the term of office. The immunity is absolute as to criminal process and is not confined to acts done in the discharge of official functions, which distinguishes it from the immunity in Article 361(1). It is an immunity from process rather than from liability, so proceedings may be instituted once the term ends. Article 361(3) adds that no process for arrest or imprisonment shall issue during the term, and Article 361(4) requires two months notice before civil proceedings in respect of anything done in a personal capacity.
• Statement 2 is correct. Article 158(4) provides that the emoluments and allowances of the Governor shall not be diminished during the term of office. The protection is one of the standard devices for securing the independence of a constitutional functionary, and it parallels the corresponding provisions for the President under Article 59(4) and for judges of the higher judiciary. Both statements being correct, the answer is (c). The teaching point is that these are the two conventional pillars of protection for an office of this kind, immunity from legal process during tenure and a bar on reduction of remuneration, and a candidate who recognises the pattern will accept both statements even without the article numbers.

Hence (c).

• Option (d) is correct. Bani Thani is the signature image of the Kishangarh school of Rajasthani painting, associated with the reign of Raja Sawant Singh, who wrote devotional verse under the name Nagari Das, and executed principally by the painter Nihal Chand in the middle of the eighteenth century. The subject is traditionally identified with a singer at the Kishangarh court, and the figure has been called the Indian Mona Lisa. Its formal signature is unmistakable: an extremely elongated face and neck, an exaggeratedly arched and extended eye tapering to a point, a sharply pointed nose and chin, and a stylisation so pronounced that it approaches abstraction, set within Vaishnava themes of Radha and Krishna.
• Option (a) is wrong because the Bundi school is marked by lush vegetation, dense forest and water settings, vivid skies and a distinct treatment of animals and hunting scenes.
• Option (b) is wrong because the Jaipur school runs to large formal portraiture and durbar scenes under strong Mughal influence.
• Option (c) is wrong because the Kangra school belongs to the Pahari group, and though it too is Vaishnava in theme and delicate in line, its faces are softly rounded and naturalistic and its settings are the hills, which is the opposite of the Kishangarh stylisation. Governing principle for this family of questions: identify the school by the treatment of the human face and by the landscape convention, not by the subject, since Radha and Krishna are common to several schools.

Hence (d).

• Option (c) is correct. Terminal High Altitude Area Defense is an American ballistic missile defence system, developed by Lockheed Martin and operated by the United States Army, designed to intercept short, medium and intermediate range ballistic missiles in their terminal phase at high altitude. It uses a hit to kill kinetic interceptor with no explosive warhead, destroying the target by the energy of impact, and is cued by the AN slash TPY 2 X band radar. Its deployment in the Republic of Korea from 2017 provoked sustained Chinese objection, ostensibly to the reach of the radar rather than to the interceptor.
• Option (a) is wrong: Israel's systems are Iron Dome for rockets and short range projectiles, David's Sling for medium range, and Arrow for longer range ballistic threats, and the radar in the Israeli architecture is the Green Pine rather than anything called THAAD.
• Option (b) is wrong: India's indigenous effort is the Ballistic Missile Defence programme of the Defence Research and Development Organisation, with the Prithvi Air Defence and Prithvi Defence Vehicle for exo atmospheric and the Advanced Air Defence for endo atmospheric interception.
• Option (d) is wrong: Japan and the Republic of Korea have no such joint programme, and Japan's own layered defence rests on Aegis equipped destroyers with SM 3 interceptors and on land based Patriot PAC 3. Note that the name states the function, terminal phase, high altitude, area rather than point defence, which is enough to identify it as an interceptor system rather than a radar and to eliminate option (a).

Hence (c).

• Statement 1 is incorrect. Tyagaraja was a devotee of Rama, and the overwhelming majority of his kritis are addressed to Rama, including the five Pancharatna kritis and the Utsava Sampradaya and Divya Nama Sankirtanas; his two musical dramas are the Prahlada Bhakti Vijayam and the Nauka Charitram, the latter alone being on a Krishna theme.
• Statement 2 is correct. Tyagaraja composed in ragas he himself brought into use, among them Kharaharapriya, Harikambhoji and Devagandhari as commonly cited, and he is credited with establishing the kriti as the principal form of Carnatic concert music in its three part structure of pallavi, anupallavi and charanam.
• Statement 3 is incorrect and is the sharpest elimination in the question, because the two composers are separated by roughly three centuries. Annamacharya, or Annamayya, belongs to the fifteenth century and died in 1503; Tyagaraja lived from 1767 to 1847.
• Statement 4 is correct. Annamacharya was attached to the temple at Tirumala and his sankirtanas are addressed to Venkateshwara, thousands of them inscribed on copper plates preserved there. So statements 2 and 4 are correct and the answer is (b). Elimination route: rejecting the contemporaneity in statement 3 removes options (a), (c) and (d) at a stroke, leaving (b) without any need to assess the remaining statements. The chronological anchor is worth carrying, since Annamacharya precedes the Carnatic trinity of Tyagaraja, Muthuswami Dikshitar and Syama Sastri by some three hundred years.

Hence (b).

• Statement 1 is correct. Limitation of powers is the core of the rule of law: government acts only under authority conferred by law, so no organ of the State enjoys arbitrary or unlimited power. In the Indian setting this is given effect by the enumeration of legislative competence, by judicial review and by the requirement that executive action rest on a legal source.
• Statement 2 is correct and is Dicey's second principle, equality before the law, that no person is above the law and all are subject to the ordinary law administered by the ordinary courts. Article 14 embodies it.
• Statement 3 is incorrect and it is incorrect because it is inverted. Under the rule of law the Government is responsible to the people, through the legislature, the courts and the electorate; the people are not answerable to the Government. Recognising the inversion is the whole task of the question.
• Statement 4 is correct. Liberty and civil rights are treated as features rather than merely consequences, since Dicey's third principle located the sources of constitutional liberty in judicial decisions enforcing individual rights, and in India Part III performs the same function. So statements 1, 2 and 4 are correct and the answer is (c). Elimination route: rejecting statement 3 removes options (a) and (d) together, and the remaining choice between (b) and (c) turns on whether limitation of powers counts as a feature, which it plainly does, since a government of unlimited power is the definition of the condition the rule of law exists to prevent.

Hence (c).

• Option (b) is correct. Legal tender is money that a creditor is legally obliged to accept in discharge of a debt, so that a valid tender of it extinguishes the obligation and the creditor who refuses it cannot afterwards complain of non payment. In India, banknotes issued by the Reserve Bank are legal tender under section 26 of the Reserve Bank of India Act, 1934, guaranteed by the Central Government, and coins are legal tender under the Coinage Act, subject to limits by denomination, which is why one rupee coins are unlimited legal tender while very small denominations are limited.
• Option (a) is wrong: it reads legal tender as money tendered in a court of law, which is a play on the word legal and has no economic content.
• Option (c) is wrong and is the most instructive elimination, because cheques, drafts and bills of exchange are precisely the classic examples of optional or non legal tender money; a creditor is entitled to refuse a cheque, which is why a cheque is only a conditional discharge and the debt revives if it is dishonoured.
• Option (d) is wrong because it confines legal tender to metallic money, whereas the great bulk of legal tender in any modern economy is paper currency, and the distinction between legal and optional tender does not track the distinction between metal and paper at all. Governing principle: legal tender is defined by the compulsion on the receiver, not by the material of the money or by the identity of the issuer.

Hence (b).

• Option (c) is correct. Opportunity cost is the value of the next best alternative forgone, and it attaches to the use of resources, not to the act of payment. When the Government supplies a commodity without charge, the resources used to produce it are still withdrawn from other uses, so the cost does not disappear; what changes is who bears it. The user no longer bears it at the point of consumption, and it is borne instead by the taxpayers whose contributions finance the provision. The incidence shifts; the cost does not.
• Option (a) is wrong because it confuses price with cost, which is the error the question is built to expose: a zero price does not make a good free in the economic sense, and this is the sense of the maxim that there is no such thing as a free lunch.
• Option (b) is wrong because ignoring a cost is a description of faulty accounting rather than of what happens economically, and in any case the cost continues to be borne whether or not anyone records it.
• Option (d) is the strongest distractor and is wrong on a point worth pressing with students: the Government is not an independent source of resources and bears nothing of its own. It is a conduit that raises revenue from taxpayers, borrows against future taxpayers, or expands money, so naming the Government as the bearer merely postpones the question of who ultimately pays. Governing principle: trace opportunity cost to the party whose alternatives are actually forgone, and that party is always a set of persons, never an institution.

Hence (c).

• Option (c) is correct. The question turns on the distinction between growth and development. Growth is a quantitative expansion of output, measured here by absolute and per capita real Gross National Product. Development is a qualitative and distributional notion, concerned with whether the expansion translates into improved living conditions, wider capabilities and reduced deprivation. Rising per capita income is an average, and an average can rise while the median stagnates and the lower deciles fall further behind, which is precisely what happens when growth is concentrated in capital intensive sectors that generate little employment. If poverty and unemployment increase alongside rising per capita output, the growth has not been development, and the mismatch is definitional rather than incidental.
• Options (a) and (b) are wrong for a shared reason: a shift in the sectoral balance between agriculture and industry is a normal feature of structural transformation and says nothing by itself about welfare. Indeed option (b), industry outpacing agriculture, is the classic pattern of successful development, so treating it as evidence against development inverts the standard account.
• Option (d) is wrong because a widening trade deficit is a balance of payments matter and may accompany rapid development, for instance where imports are capital goods financed by investment inflows. Governing principle: development is judged by distribution and by human outcomes, so among four options only the one referring to poverty and employment can qualify.

Hence (c).

• Statement 2 is correct and is the definition itself. Human capital formation is the process of raising the knowledge, skills, competences and health of a population, through education, training, work experience, nutrition and health care, so that labour becomes more productive.
• Statement 4 is correct. What is accumulated is embodied in persons and cannot be separated from them, so it is intangible wealth: it does not appear on a balance sheet, cannot be transferred by sale and is extinguished with the person.
• Statement 3 is incorrect for the same reason, since tangible wealth means physical assets such as plant, machinery, buildings and inventories, and their accumulation is physical capital formation, a different process.
• Statement 1 is incorrect and is the trap in the question. Reading capital in its ordinary financial sense, the statement describes individuals accumulating more assets or savings, which is neither the definition of human capital nor its object; human capital formation is about the augmentation of capacities, and greater private wealth is at most a consequence of it. So statements 2 and 4 are correct and the answer is (c). Elimination route: statement 3 is the cleanest reject, and rejecting it removes option (d); recognising that statement 2 must be included removes nothing further, so the decision rests on whether to add statement 1 or statement 4, and the tangible against intangible pairing in statements 3 and 4 signals that the examiner wants intangible.

Hence (c).

• Option (d) is correct, and the reasoning is arithmetical rather than a matter of recall. The capital to output ratio measures how much capital is needed to produce one unit of output, and in incremental form the growth rate equals the saving and investment rate divided by the incremental capital to output ratio, which is the Harrod Domar relation. If that ratio is high, each unit of investment buys correspondingly little additional output, so even a high saving rate delivers weak growth. A high ratio arises where investment is concentrated in long gestation and capital intensive projects, or where existing capital is used inefficiently and capacity lies idle.
• Option (a) is wrong not because weak administration is harmless but because it is an indirect and non quantitative explanation; it may raise the capital to output ratio, and so operates through option (d) rather than alongside it.
• Option (b) is wrong for the same structural reason: illiteracy depresses the productivity of labour and of human capital, and its effect on the return to physical investment is again mediated.
• Option (c) is wrong because population density has no determinate relation to the productivity of capital at all, high density economies such as the Netherlands, Japan and Singapore being among the most productive. Governing principle: the question asks what can defeat a high saving rate, and only the capital to output ratio stands in a direct arithmetical relation to the saving rate in the determination of growth. That is the elimination route, and it works without weighing the plausibility of the other three.

Hence (d).

• Statement 1 is correct. After the Santhal hool of 1855 to 1856 led by Sidhu and Kanhu Murmu was suppressed, the colonial government carved out a separate administrative unit, the Santhal Parganas, from parts of Bhagalpur and Birbhum, and placed it under a non regulation regime in which the ordinary laws and the ordinary civil courts of Bengal did not apply and a Deputy Commissioner exercised combined executive and judicial authority.
• Statement 2 is correct. Restrictions on the alienation of Santhal land to outsiders were imposed as part of the same settlement and were consolidated later in the Santhal Parganas Tenancy Act, so that transfer of land by a Santhal to a non Santhal was barred. Both statements being correct, the answer is (c). The governing logic is worth teaching because it repeats across colonial tribal policy. The revolt was driven by dispossession at the hands of the dikus, the moneylenders, traders and revenue farmers who had acquired Santhal land through debt, so the administrative response addressed the cause in two ways: territorial insulation through a separately administered tract, and legal insulation through a bar on land transfer. The same pattern appears in the Chotanagpur Tenancy Act of 1908 after Birsa Munda's ulgulan and in the scheduled and excluded areas of the Government of India Act, 1935, which are the ancestors of the Fifth and Sixth Schedules.

Hence (c).

• Option (c) is correct. The commercialisation of agriculture is the standard characterisation of the nineteenth century transformation: cultivation shifted from subsistence food grains towards cash crops such as indigo, opium, cotton, jute, tea and oilseeds grown for distant markets, driven by the cash demands of the revenue settlements, by the credit of the moneylender, by the railways that opened interior markets, and by the raw material needs of British industry. Its consequences were a peasantry exposed to world price movements without any cushion, deepening rural indebtedness and a reduced margin of food security, which is why the great famines of the period coincided with rising agricultural exports.
• Option (a) is wrong and inverts the direction of change; Indian handicraft exports collapsed under competition from machine made British goods, a process usually described as deindustrialisation, and India moved from being an exporter of finished textiles to an exporter of raw cotton.
• Option (d) is wrong for a connected reason: artisans displaced from crafts largely fell back on agriculture rather than moving to towns, so the nineteenth century saw ruralisation rather than rapid urbanisation, and the urban share of population was broadly stagnant.
• Option (b) is the strongest distractor, since Indian owned cotton mills did appear in Bombay and Ahmedabad from the 1850s and jute and steel followed, but this was a limited late century development concentrated in a few centres and confined to a narrow range of industries, and it does not describe the economy as a whole in the way that option (c) does. The elimination turns on choosing the change that was general rather than the one that was real but partial.

Hence (c).

• Option (b) is correct and is the text of Article 356(1)(b), which provides that on a Proclamation the President may declare that the powers of the Legislature of the State shall be exercisable by or under the authority of Parliament.
• Option (a) is wrong. Dissolution of the Assembly is not automatic; the Proclamation may either dissolve the Assembly or keep it in suspended animation, and after S. R. Bommai in 1994 the settled position is that the Assembly should not be dissolved before both Houses of Parliament have approved the Proclamation, since dissolution is irreversible while a suspension is not.
• Option (c) is wrong and rests on confusing two distinct emergencies. Article 19 is suspended automatically only under Article 358, and only when a National Emergency is proclaimed on the ground of war or external aggression, a restriction introduced by the Forty fourth Amendment; a Proclamation under Article 356 suspends no Fundamental Right. This is the single most useful discrimination in the question.
• Option (d) is wrong on the identity of the law making authority. Under Article 357 Parliament may confer on the President the power of the Legislature of the State and may authorise the President to delegate it further, and when Parliament is not in session the President may promulgate ordinances; but the power originates in Parliament and the President does not acquire an independent legislative competence over the State. Note that Article 356 does not permit Parliament to assume the powers of the State High Court, which the proviso to Article 356(1) expressly protects.

Hence (b).

• Pair 1 is correctly matched. The puthukuli is the embroidered shawl of the Toda community of the Nilgiri hills in Tamil Nadu, worked in red and black on a coarse white cotton ground in a distinctive counted thread technique that is reversible, and Toda embroidery carries a geographical indication registered to Tamil Nadu.
• Pair 2 is incorrectly matched. Sujni embroidery belongs to Bihar, principally the Muzaffarpur area, where old cloth is layered and quilted with running stitch and figurative motifs; it holds a geographical indication for Bihar, not Maharashtra.
• Pair 3 is incorrectly matched. Uppada is a coastal village in East Godavari district of Andhra Pradesh, and the Uppada Jamdani sari, woven in the jamdani technique in which the motif is inserted by hand during weaving rather than added afterwards, is an Andhra Pradesh craft, not a Karnataka one. Only pair 1 is correct, so the answer is (a). This is a difficult item because there is no reasoning route at all; each pair must be known independently and the options are constructed so that no single rejection settles the answer. Recognising Uppada as Andhra removes options (c) and (d) but still leaves (a) against (b), which turns on Sujni. The one usable heuristic is that jamdani weaving in India is associated with Bengal and with the Andhra coast rather than with the Karnataka silk tradition, which runs to Mysore silk and Ilkal.

Hence (a).

All three are correct, and the reason is the same in each case, which is the point the question is really testing. A GPS receiver solves for four unknowns, three of position and one of time, so the system is as much a distributed atomic clock as a positioning service, and its precise timing signal is used far more widely than its coordinates.

• Statement 1 is correct: cellular base stations must be synchronised to a common time reference for handover between cells and for the timing structure of the air interface, and GPS disciplined oscillators are the usual source.
• Statement 2 is correct: banking and financial networks use GPS derived time to timestamp transactions, to sequence entries across distributed systems and to meet audit and regulatory requirements on clock accuracy, and this is the statement candidates most often reject because they think only of navigation.
• Statement 3 is correct: the phasor measurement units on which wide area monitoring of a power grid depends compare voltage and current phase angles at points hundreds of kilometres apart, and comparing phase across such distances is meaningless unless every unit is stamping its readings against the same clock to within microseconds. Since no statement can be rejected, only option (d) survives. Governing principle to carry: whenever GPS appears in a question outside navigation, ask whether the application needs a common time reference, and if it does the answer is almost always yes.

Hence (d).

• Statement 1 is incorrect and it is the decisive statement. The Reserve Bank of India is banker and debt manager to the Central Government under the Reserve Bank of India Act, and it performs the same function for the State Governments under separate agreements entered into with each State, conducting their auctions of State Development Loans, servicing the interest and redemption and extending Ways and Means Advances. The word not in the statement is therefore wrong.
• Statement 2 is correct. Treasury bills are short term instruments of the Central Government alone, issued in 91, 182 and 364 day tenors; State Governments raise market borrowing through dated securities, the State Development Loans, and have no treasury bill of their own, their short term needs being met by Ways and Means Advances and overdrafts from the Reserve Bank.
• Statement 3 is correct. Treasury bills are zero coupon instruments sold below face value and redeemed at par, the difference between issue price and face value being the return to the holder, so the yield is realised as capital appreciation rather than as periodic interest. Elimination route: accepting statement 3 removes option (a), accepting statement 2 removes option (b), and the choice between (c) and (d) rests entirely on statement 1. The reasoning shortcut is that a central bank which is banker to the Union and holds the accounts of the States could hardly decline to service State debt, and in practice the Reserve Bank's monopoly of government debt management at both levels is one of its defining functions.

Hence (c).

• Statement 2 is incorrect and it is the obvious reject that opens the question. The early Earth had essentially no free oxygen. Its primordial atmosphere was lost, and the secondary atmosphere produced by degassing of the interior was dominated by water vapour, carbon dioxide, nitrogen, methane and ammonia. The statement inverts the actual composition on both counts, asserting abundant oxygen and absent carbon dioxide when the truth is the reverse, and the figure of 54 per cent has no basis. Free oxygen is a product of life, not a precondition for it.
• Statement 3 is correct and follows directly. Photosynthesising cyanobacteria released oxygen, which was first consumed by dissolved iron and by reduced minerals, producing the banded iron formations, and only when those sinks were exhausted did oxygen accumulate in the atmosphere in the Great Oxidation Event around 2400 million years ago. That accumulation in turn created the ozone screen and made the colonisation of land possible, so the biosphere reconstructed the atmosphere it now depends on.
• Statement 1 is correct as the key takes it. Reversals of the geomagnetic field are recorded in the magnetisation of successive lavas and in the symmetrical magnetic striping of the ocean floor about the mid ocean ridges, which was the decisive evidence for sea floor spreading, and the most recent full reversal, the Brunhes Matuyama, was about 780,000 years ago. So statements 1 and 3 are correct and the answer is (c). Elimination route: rejecting statement 2 removes options (b) and (d) at once, leaving (a) against (c), and statement 3 is then almost self evidently true for anyone who knows that atmospheric oxygen is biogenic.

Hence (c).

• Option (c) is correct. All three terms belong to the same episode. EternalBlue is an exploit of a flaw in Microsoft's Server Message Block version 1 protocol, developed by the United States National Security Agency and released publicly by the Shadow Brokers group in April 2017. WannaCry, which spread worldwide in May 2017 and crippled parts of the British National Health Service among many others, was ransomware that used EternalBlue to propagate from machine to machine without user action, which is what made it a worm rather than an ordinary ransomware campaign. Petya, and more precisely the NotPetya variant of June 2017, used the same exploit but destroyed data irrecoverably while presenting itself as ransomware.
• Option (b) is the strongest distractor and is worth addressing carefully, because ransomware demands payment in Bitcoin and the two subjects are therefore linked in news coverage. The link is incidental: cryptocurrency is the payment channel, not the subject, and none of the three terms names a currency, a protocol or an exchange.
• Options (a) and (d) fail on domain, exoplanets and small satellites being unrelated to any of the three names. Governing principle for terms in news questions of this shape: find the single event that accounts for all the terms together rather than assessing each in isolation, since the examiner groups them precisely because they share one origin.

Hence (c).

Conservation Agriculture as defined by the Food and Agriculture Organization rests on three interlinked principles, and options 2, 4 and 5 are precisely those three.

• Statement 2 is correct: minimum mechanical soil disturbance, that is zero or reduced tillage with direct seeding, preserves soil structure, protects the fungal networks and earthworm channels that create macroporosity, and prevents the oxidation of soil organic carbon that ploughing accelerates.
• Statement 4 is correct: permanent organic soil cover through retained crop residues or cover crops shields the surface from raindrop impact and from insolation, cuts erosion and evaporation, moderates soil temperature and feeds the soil biota.
• Statement 5 is correct: diversification through crop rotations and spatial and temporal sequencing breaks pest and disease cycles, varies rooting depth and nutrient demand, and permits legumes to fix nitrogen.
• Statement 3 is incorrect: nothing in Conservation Agriculture concerns which commodity is grown, and plantation crops are perennial systems to which the framework is simply not addressed. Its presence in three of the four options is the device that makes the question workable, since rejecting it eliminates (a), (b) and (d) together and leaves (c) without further reasoning. Hence (c). The governing principle is worth stating as the examiner intends it: Conservation Agriculture is defined by how the soil is managed, through disturbance, cover and rotation, and not by what is planted.

• Option (d) is correct. The Earth's fossil record shows five mass extinctions, at the end of the Ordovician, in the Late Devonian, at the end of the Permian, at the end of the Triassic and at the end of the Cretaceous, each defined by the loss of a very large fraction of species in a geologically short interval. The sixth extinction is the proposition that a comparable event is under way now and that its cause is human, operating through the destruction and fragmentation of habitat, overexploitation of species, pollution, invasive species and climate change, with current extinction rates estimated at tens to hundreds of times the background rate.
• Option (d) alone names that composite set of drivers.
• Option (b) is the most instructive elimination, because it describes the cause of the fifth extinction, the end Cretaceous bolide impact, and offers it as the cause of the sixth. The whole force of the term is that this one is anthropogenic and already occurring, not extraterrestrial and prospective, so an option that returns the cause to a meteorite misses the point entirely.
• Options (a) and (c) are each real concerns, monoculture and chemical intensification in the first, genetically modified crops displacing landraces in the second, but both describe agricultural biodiversity loss, which is one narrow channel among many and cannot by itself constitute a mass extinction. Governing principle: mass extinction is a claim about species loss across all taxa and all biomes, so the correct option must be the one whose drivers are general rather than sectoral.

Hence (d).

• Statement 1 is correct and matches the published constellation design. IRNSS, operationally named NavIC, comprises seven satellites, three placed in geostationary orbit over the equator and four in inclined geosynchronous orbits that trace a figure of eight ground track, two of them crossing the equator at about 55 degrees east and two at about 111.75 degrees east. The inclined satellites exist to give good elevation angles over the whole service area, which a purely equatorial arrangement could not provide at northern latitudes.
• Statement 2 is incorrect on both the number and the unit, and the unit error alone should catch a careful reader. The service area extends about 1500 kilometres beyond India's borders, not 5500, and a coverage footprint beyond a border is a distance rather than an area, so the expression square kilometres beyond its borders is meaningless as written.
• Statement 3 is incorrect and contradicts the name of the system. IRNSS is by design a regional constellation; global coverage would require a far larger constellation in medium Earth orbit of the kind operated by GPS, GLONASS, Galileo and BeiDou, and India has announced no such system with a 2019 horizon. Elimination route: statement 3 can be rejected on the word Regional in the system's own title, which removes options (c) and (d); statement 2 then falls on the unit, leaving (a).

Hence (a).

• Statement 3 is the central content of the theory and is correct. General relativity replaces gravity as a force with the geometry of spacetime: the Einstein field equations relate the curvature of spacetime to the distribution of energy and momentum, so matter tells spacetime how to curve and curved spacetime tells matter how to move.
• Statement 1 is correct and is a direct consequence of statement 3. Since light follows null geodesics of the curved geometry, its path bends near a massive body, and it also loses frequency climbing out of a potential well. The deflection of starlight by the Sun measured at the 1919 eclipse was the observation that made the theory famous, and gravitational lensing is now a working tool of astronomy. Note that the Newtonian corpuscular calculation also predicts a deflection but only half the relativistic value, so the effect discriminates between the two theories rather than merely confirming that light responds to gravity.
• Statement 2 is the contested one and the key accepts it. The justification is that the field equations admit no stable static solution: Friedmann in 1922 and Lemaitre in 1927 showed that the generic cosmological solutions of general relativity are dynamic, either expanding or contracting, and Einstein had introduced the cosmological constant in 1917 precisely to force a static universe, later regarding that step as a mistake once Hubble's observations established recession. On that reading a non static universe is indeed a prediction of the theory and option (d) follows.

Hence (d).

• Statement 1 is incorrect and this is where most candidates go wrong, because the phrase genes of a soil bacterium is correct while the function attributed to them is not. DMH 11 carries the barnase, barstar and bar genes from Bacillus amyloliquefaciens, a soil bacterium, but these do not confer pest resistance. Barnase is a ribonuclease expressed in the tapetum that destroys pollen development and so induces male sterility; barstar is its specific inhibitor, restoring fertility in the hybrid; bar confers tolerance to the herbicide glufosinate and serves as the selectable marker. The pest resistance idea is imported from Bt cotton and brinjal, where the gene is from Bacillus thuringiensis and does confer insect resistance, and the examiner is testing whether the candidate can keep the two bacteria and the two purposes apart.
• Statement 2 is correct and describes exactly what the barnase and barstar system is for. Mustard is a self pollinating crop, which makes controlled crossing laborious and hybrid seed production commercially impractical; engineered male sterility with a fertility restorer supplies the tool that allows hybridisation and the capture of hybrid vigour.
• Statement 3 is incorrect. DMH 11 was developed by the Centre for Genetic Manipulation of Crop Plants at the University of Delhi South Campus under Deepak Pental, not by the Indian Agricultural Research Institute with Punjab Agricultural University. Elimination route: rejecting statement 3 removes options (a), (c) and (d) together and settles the question on one fact.

Hence (b).

• Pair 3 is incorrectly matched and it settles the question on its own. CRISPR Cas9 is a genome editing tool, adapted from a bacterial adaptive immune system in which short repeats store fragments of past viral invaders and the Cas9 nuclease, guided by a matching RNA, cuts double stranded DNA at a chosen sequence. It belongs to molecular biology and has nothing to do with particle physics. Since pair 3 appears in options (a), (c) and (d), rejecting it eliminates all three at once and leaves (b), which is why a candidate who knows only this one fact can answer with confidence.
• Pair 1 is also incorrectly matched, and the two errors are a straight swap. Belle II is a particle physics detector at the SuperKEKB electron positron collider at KEK in Japan, built to study rare decays of B mesons and charge parity violation, and thereby to look for physics beyond the Standard Model.
• Pair 2 is correctly matched. Blockchain is the distributed append only ledger, secured by cryptographic hashing and a consensus mechanism, on which Bitcoin and other cryptocurrencies are built, though the technology has applications well beyond currency, in land records, supply chain provenance and settlement systems.

Hence (b).

• Option (a) is correct. Carbon dioxide is a substrate of photosynthesis, and in C3 plants the carboxylating enzyme rubisco is not saturated at present atmospheric concentrations and also catalyses a competing reaction with oxygen, photorespiration, which wastes fixed carbon. Raising the ambient carbon dioxide concentration therefore increases the rate of net carbon assimilation and suppresses photorespiration, and it additionally allows stomata to open less widely for the same carbon gain, improving water use efficiency. The result is the growth enhancement the term names. The effect is significant for C3 crops such as wheat and rice and much weaker in C4 plants such as maize and sugarcane, which already concentrate carbon dioxide at the site of fixation, and it is limited in the field by nitrogen, phosphorus and water availability, which is why free air enrichment experiments yield smaller gains than glasshouse studies and why the protein and micronutrient content of the resulting grain tends to fall.
• Options (b) and (c) are wrong not because they are false statements but because they name different consequences of the same cause: (b) is the greenhouse effect and (c) is ocean acidification, the dissolution of carbon dioxide as carbonic acid lowering seawater pH.
• Option (d) is wrong as a proposition in its own right, since adaptation of all living beings is not an observed phenomenon and is the opposite of the extinction pressure discussed in question 60 of this paper. Governing principle: the word fertilization points to plant nutrition, so among four true sounding consequences of rising carbon dioxide the correct one must be the one about growth.

Hence (a).

• Option (b) is correct. The scenario describes ordinary physical objects, a water heater, a mirror, a tank, a refrigerator, lighting and a car, each fitted with sensors and network connectivity so that they can gather data about their own state and about their environment, exchange it and act on it without human intervention. That is precisely the Internet of Things: the extension of network connectivity from computers and phones to everyday devices, together with the machine to machine communication and automated decision making that follows from it.
• Option (a) is wrong: the Border Gateway Protocol is the routing protocol that exchanges reachability information between autonomous systems and holds the backbone of the internet together; it is infrastructure invisible to any end device in this scenario.
• Option (c) is wrong for a subtler reason worth pressing, because every device described does use the Internet Protocol. But the Internet Protocol is merely the addressing and packet delivery layer, common to all networked communication whatsoever, so naming it explains nothing distinctive about the scenario; the question asks which term best applies, and a term that applies equally to sending an email is not the best fit.
• Option (d) is wrong: a Virtual Private Network is an encrypted tunnel that extends a private network across a public one, a security and access mechanism unrelated to device autonomy. Governing principle: identify what is novel in the description, which is that inanimate objects are the actors, and only one of the four terms names that.

Hence (b).

• Statement 1 is incorrect. India has almost no capacity in the upstream stages of the photovoltaic value chain. That chain runs from polysilicon to ingots, then wafers, then cells, then modules, and Indian manufacturing is concentrated almost entirely at the module assembly end, with limited cell capacity and effectively no commercial polysilicon, ingot or wafer production. China dominates wafer manufacture with a share above ninety per cent, and it is precisely this dependence on imported cells and wafers that prompted the safeguard duty debate of 2018 and the later production linked incentive scheme for solar modules.
• Statement 2 is incorrect and turns on the distinction between discovering a price and determining a tariff. The Solar Energy Corporation of India is a central public sector undertaking under the Ministry of New and Renewable Energy that acts as an implementing agency and an intermediary offtaker; it conducts reverse auctions in which developers bid, and the winning bid establishes the price. Determination and adoption of tariffs is a regulatory function vested in the Central Electricity Regulatory Commission and the State Electricity Regulatory Commissions under the Electricity Act, 2003, which adopt a competitively discovered tariff or fix one where there has been no competitive bidding. Both statements failing, the answer is (d). Elimination route: statement 2 rewards the general principle that in the Indian power sector the entity that runs a procurement is not the entity that regulates a tariff, and statement 1 rewards awareness that India imports the great bulk of its solar hardware.

Hence (d).

• Option (d) is correct. In the middle of the eighteenth century, before the reversal brought about by British industrialisation, Bengal was an exporter of manufactures and of high value raw produce. Cotton piece goods, above all the fine muslins of Dacca, and Bengal raw and wrought silk were the principal items; saltpetre, that is potassium nitrate, was mined in Bihar and was strategically important as the oxidiser in gunpowder, which made it a commodity European powers competed for; and opium, produced in Bihar and Bengal, was becoming the article on which the Company's China trade would later be built.
• Option (a) is wrong because it describes the export pattern of the nineteenth century rather than the eighteenth, when raw cotton and oilseeds flowed out to feed British industry, and it omits textiles altogether, which is the decisive omission for this period.
• Option (b) is wrong because sugar, salt, zinc and lead were not Bengal's staples, and salt in particular was a domestically monopolised and consumed commodity rather than an export.
• Option (c) is wrong on the direction of trade: copper, silver and gold moved into Bengal, silver bullion especially, since Europe had little that Bengal wanted and settled its purchases in specie, and this drain of bullion into India is the standard complaint of contemporary English pamphleteers. Tea came from China, not Bengal, in this period. Governing principle: for the mid eighteenth century ask what India sold rather than what Britain later extracted, and the answer is finished textiles.

Hence (d).

• Option (c) is correct. Champaran in 1917 was Gandhi's first satyagraha in India and its historical significance lies in what it joined together. The grievance was that of the indigo ryots of north Bihar, held under the tinkathia system to cultivate indigo on a fixed portion of their holding for the European planters, and burdened with illegal cesses after synthetic dye had destroyed the market for the crop. By taking up that agrarian grievance, defying the order to leave the district, and securing the Champaran Agrarian Enquiry Committee on which he sat and the Champaran Agrarian Act of 1918, Gandhi brought a local peasant struggle inside the national movement and demonstrated that the Congress could be an organisation of the countryside rather than of the professional urban classes alone. That linkage is the answer.
• Option (a) is wrong on scale and on timing: participation was local, drawing in Bihari lawyers such as Rajendra Prasad, Brajkishore Prasad and Anugrah Narayan Sinha, and the all India participation of students and women belongs to the Non Cooperation and Civil Disobedience movements of the 1920s and 1930s.
• Option (b) is wrong because Champaran was not a Dalit or tribal mobilisation; the cultivators were tenants of the indigo estates.
• Option (d) is wrong on fact and on framing, since the decline of indigo cultivation followed from the collapse of the market for natural dye rather than from the satyagraha, and a change in cropping pattern would in any case be an economic outcome rather than a significant aspect of a political movement.

Hence (c).

• Option (d) is correct. The Hind Mazdoor Sabha was founded at Howrah in December 1948 by socialists who had left the Congress, together with elements of the Indian Federation of Labour, and Ashok Mehta, T. S. Ramanujam and G. G. Mehta are named as its founders. Its formation completes the fragmentation of the Indian trade union movement along party lines in the years around independence: the All India Trade Union Congress of 1920 came under Communist control, the Indian National Trade Union Congress was founded in 1947 as the Congress affiliate, the Hind Mazdoor Sabha in 1948 as the Socialist body, and the United Trades Union Congress followed in 1949.
• Option (a) is wrong because Krishna Pillai, Namboodiripad and K. C. George were founders of the Communist movement in Kerala and are associated with the formation of the Communist Party unit there, not with a socialist trade union centre.
• Option (b) is a deliberately implausible grouping, since Jayaprakash Narayan, Deen Dayal Upadhyay and M. N. Roy belonged to three mutually opposed political traditions, socialist, Hindu nationalist and radical humanist after Roy's break with communism, and would not have founded a single organisation together; Jayaprakash Narayan's presence is the bait.
• Option (c) is wrong and is chronologically incoherent, Veeresalingam Pantulu having died in 1919, three decades before the event. Elimination route: the internal inconsistency of options (b) and (c) can be seen without knowing anything about the Hind Mazdoor Sabha, and option (a) can be rejected on the Communist identity of its three names, which leaves (d). Hence (d). Rated Difficult because the correct option contains no famous name and can only be reached by discrediting the other three.

• Option (b) is correct. The Sthanakvasi are a sect of Svetambara Jainism, founded in the seventeenth century by Lavaji and tracing its impulse to the fifteenth century reformer Lonka Shah. Its defining position is the rejection of idol worship and of temple based ritual, on the argument that image worship finds no sanction in the canonical texts and involves himsa. Sthanakvasi monks and nuns therefore worship in a plain hall, the sthanak from which the sect takes its name, rather than in a temple, and they wear the muhpatti, a strip of cloth over the mouth, to avoid harm to airborne life.
• Options (c) and (d) are wrong for a reason that also supplies the elimination: Vaishnavism and Shaivism are the two great theistic streams of Hinduism and both are centrally organised around temple worship and image devotion, so a sect defined by the rejection of idols could hardly belong to either.
• Option (a) is wrong, and it is the plausible distractor because Buddhism and Jainism are grouped together as the heterodox traditions and Buddhism has its own non theistic strands; but the Sthanakvasi are not a Buddhist school, and Buddhism's Indian sectarian divisions run along the Theravada, Mahayana and Vajrayana lines rather than through this dispute. Placing the sect correctly also fixes the wider map of Jain divisions: Digambara and Svetambara at the first level, and within the Svetambara the image worshipping Murtipujaka against the non image worshipping Sthanakvasi and the later Terapanthi, which broke from the Sthanakvasi in the eighteenth century.

Hence (b).

• Statement 1 is incorrect. Fatehpur Sikri is built overwhelmingly in the local red sandstone of the ridge on which it stands, and the Buland Darwaza, raised by Akbar to commemorate the Gujarat campaign and one of the tallest gateways in the world, is red sandstone with inlay and outlining in white and black marble. Marble is used as an accent, not as the fabric. The one substantially marble structure at the site is the tomb of Salim Chishti, which is precisely why candidates over generalise from it to the whole complex.
• Statement 2 is incorrect. The Bara Imambara and the Rumi Darwaza, built under Asaf ud Daula from 1784, use neither red sandstone nor marble. They are constructed of lakhauri brick set in lime mortar and finished in lime plaster and stucco, and the celebrated central hall of the Imambara, roughly fifty metres by fifteen and unsupported by beams or pillars, is a brick vault whose stability depends on interlocking brickwork rather than on stone. The building was raised as a famine relief work, which is part of the reason for the choice of the cheap and locally available material and for the reliance on plaster ornament rather than stone carving. Both statements failing, the answer is (d). Governing principle worth teaching: read Indo Islamic architecture by its material regions. The Mughal imperial centres of Agra, Fatehpur Sikri and Delhi work in red sandstone with marble inlay, shifting to full marble under Shah Jahan; the Awadh nawabi architecture of Lucknow works in brick and stucco, which is why its surfaces are moulded and painted rather than carved.

Hence (d).

• Option (b) is correct. Jean Baptiste Tavernier was a French gem merchant who made six voyages to the East between 1630 and 1668 and whose Les Six Voyages describes the diamond mines of India at first hand, including Kollur on the Krishna in Golconda, together with the methods of working them, the organisation of the labour and the trade in stones. He is the traveller who handled the stones professionally, and the Hope diamond descends from a stone he sold in France, which is why his account of diamonds is the detailed one.
• Option (a) is wrong on emphasis rather than on presence. Francois Bernier was a physician attached to Dara Shukoh and later to Danishmand Khan, and his Travels in the Mogul Empire is the great political and social account of the war of succession, of Mughal administration and of the absence of private property in land, but it is not a treatise on mining.
• Option (c) is wrong: Jean de Thevenot travelled in India in the 1660s and left useful descriptive notes on towns, routes and manners, but he was a scholarly traveller rather than a merchant and did not write on the diamond trade in comparable detail.
• Option (d) is wrong: Abbe Barthelemy Carre travelled as an emissary in the 1670s and his account is chiefly diplomatic and narrative. Governing principle for the seventeenth century French travellers, who are regularly confused: match the traveller to the occupation. Bernier was a physician and writes politics, Tavernier was a jeweller and writes gems and trade, Thevenot was a scholar and writes description, Carre was an envoy and writes missions.

Hence (b).

• Option (c) is correct. Maitreya is the future Buddha of Mahayana and indeed of Theravada tradition, at present a bodhisattva residing in the Tushita heaven and awaiting the age in which the teaching of Shakyamuni has been forgotten, when he will descend, attain enlightenment and preach the dharma anew. He is the fifth and last of the Buddhas of the present aeon and is conventionally shown seated in the European fashion with both legs pendant, in expectation of his descent, and carrying a stupa in the crown and a water vessel.
• Options (a), (b) and (d) fail together and for the same reason, which is the clean elimination in the question: Avalokiteshvara, Lokesvara and Padmapani are three names for a single figure, the bodhisattva of compassion, Padmapani meaning lotus bearer and Lokesvara lord of the world, and he is a present rather than a future bodhisattva, vowed to remain until all beings are liberated. Since three options denote one figure and the question asks for one answer, none of the three can be correct, and the odd name out must be the answer even for a candidate who has no independent knowledge of Maitreya. The Ajanta painting known as Padmapani is the best known Indian image of that figure and reinforces the identification.

Hence (c).

The question asks for the single statement that does not apply, so three of the four must describe the system correctly.

• Option (a) applies. The essence of the Subsidiary Alliance was that the allied Indian ruler kept a British force within his territory and paid for it, so the Company maintained a large standing army at the expense of the Indian states rather than of its own treasury, and it did so while stationing that army forward, on the territory of potential adversaries.
• Option (b) applies. Wellesley arrived in 1798 with the French threat uppermost, Napoleon then in Egypt and French officers serving Tipu Sultan, the Nizam and the Marathas, and the exclusion of Europeans other than the English from the courts of allied rulers was a standing clause of the alliances, so keeping India secure against French designs was an explicit object.
• Option (d) applies. The allied ruler surrendered control of external relations, could neither make war nor negotiate with another state without the Company's consent, and accepted a British Resident at his court, which reduced him to internal sovereignty alone and established British paramountcy in substance.
• Option (c) is the statement that does not apply. The Company did not secure a fixed income from the arrangement. Payment was frequently made not in cash but by the cession of territory in perpetuity, which is how the Company acquired the Carnatic, Tanjore, Surat, parts of Awadh and the Ceded Districts from the Nizam, and where a cash subsidy was stipulated it was often in arrears, the resulting default being itself a pretext for annexation. The financial result was territorial expansion rather than a steady revenue stream.

Hence (c).

All three contributed and they form a single causal chain, which is why the answer is (d).

• Statement 1 is correct. The Charter Act of 1813 was the first legislative acknowledgement of a state responsibility for Indian education, directing that not less than one lakh of rupees be set apart annually for the revival and improvement of literature, the encouragement of the learned natives of India and the introduction and promotion of a knowledge of the sciences. The clause is deliberately ambiguous about the medium and the content, and that ambiguity produced everything that followed.
• Statement 2 is correct. The General Committee of Public Instruction was constituted in 1823 to administer that grant, and it became the forum in which the ambiguity had to be resolved, since the Committee had to decide what literature and whose sciences the money was to be spent on.
• Statement 3 is correct. Its members divided into Orientalists, led by H. T. Prinsep and favouring Sanskrit, Arabic and Persian learning and the vernaculars, and Anglicists, favouring English and Western science. The controversy was settled by Macaulay's Minute of February 1835 and Bentinck's Resolution of March 1835, which directed that funds be spent on English education. Elimination route: there is none of the usual kind, since no statement can be rejected, so the question rewards seeing the sequence rather than checking three separate facts. The chain runs from the money in 1813, through the body that had to spend it in 1823, to the dispute over how, resolved in 1835.

Hence (d).

• Option (a) is correct. The lake at Kodaikanal in the Palani hills is man made, created in 1863 when Sir Vere Henry Levinge dammed a hollow in the hills and stocked it with fish, and it forms the centre of a hill station laid out by Europeans in the nineteenth century.
• Option (b) is wrong. Kolleru is a natural shallow freshwater lake lying between the deltas of the Krishna and the Godavari, functioning as a natural flood balancing reservoir between the two river systems; it is a Ramsar site and was declared a wildlife sanctuary.
• Option (c) is wrong. Nainital is a natural lake of tectonic origin, occupying a depression formed along a fault in the Kumaon hills, and its crescent shape follows that structural line.
• Option (d) is wrong. Renuka is the largest natural lake in Himachal Pradesh, also a Ramsar site, and is associated in tradition with the mother of Parashurama, its outline being said to resemble a reclining woman. Governing principle for this recurring question type: hill station lakes in the peninsular hills are very often engineered, because the Palanis and the Nilgiris have no natural lake basins of any size, whereas lakes in the Himalaya and the sub Himalaya are commonly tectonic or glacial, and the large lakes of the coastal plains are lagoons or deltaic depressions. Since three of the four options are recognised natural water bodies with Ramsar or sanctuary status, the odd one out is the constructed one.

Hence (a).

• Statement 1 is incorrect and it is the only statement a candidate needs. Pradhan Mantri Kaushal Vikas Yojana is the flagship scheme of the Ministry of Skill Development and Entrepreneurship, created in 2014 precisely to consolidate skilling efforts that had until then been scattered across some twenty ministries, and it is implemented through the National Skill Development Corporation. The Ministry of Labour and Employment runs the Industrial Training Institutes and the apprenticeship framework, which is a separate stream. Since statement 1 appears in options (a) and (d), rejecting it eliminates both and leaves (b) against (c).
• Statement 2 is correct. Beyond technical skilling, the scheme provides for training in soft skills, entrepreneurship, financial literacy and digital literacy, on the reasoning that employability in the organised sector depends on workplace behaviour and basic transactional competence as much as on trade skill.
• Statement 3 is correct and states the scheme's central purpose. Recognition of Prior Learning assesses and certifies workers who acquired their skills informally, on the job or through family occupation, and maps those competencies onto the levels of the National Skill Qualification Framework, so that an existing but unrecognised skill becomes a portable and certified one. That component is what distinguishes the scheme from ordinary vocational training.

Hence (c).

• Option (a) is correct. The All India Home Rule League, founded by Annie Besant in 1916 alongside Tilak's Indian Home Rule League, came under Gandhi's presidency in April 1920, and at his instance its name was changed to Swarajya Sabha and its constitution altered to adopt the attainment of swaraj by all legitimate and peaceful means as its object. The change marks the absorption of the Home Rule agitation into the Gandhian movement, and it caused a substantial section of the older membership, including Besant herself, to withdraw, since they read the new object as a departure from the constitutional demand for self government within the Empire. The League was wound up soon afterwards as Non Cooperation took its place.
• Option (b) is wrong: the Hindu Mahasabha was founded in 1915 and reorganised in the 1920s under Malaviya and later Savarkar, and it never bore this name.
• Option (c) is wrong: the South Indian Liberal Federation, founded in 1916, was the non Brahmin party of the Madras Presidency, popularly the Justice Party after its newspaper, and it later became the Dravidar Kazhagam under Periyar rather than a Swarajya Sabha.
• Option (d) is wrong: the Servants of India Society, founded by Gokhale in 1905 to train national missionaries for constitutional and social work, continued under that name after his death. Chronological anchor: 1920 is the year Gandhi assumed the leadership of the national movement, so an organisational change in that year renaming a body around swaraj points to the vehicle he took over.

Hence (a).

• Option (b) is correct. Dinabandhu Mitra's Neeldarpan was written in 1860, and the four events in date order run: Neeldarpan in 1860, Satyendranath Tagore's success in the Indian Civil Service examination in 1863, the founding of the Arya Samaj by Dayanand Saraswati in 1875, and Bankim Chandra Chattopadhyay's Anandamath in 1882. Neeldarpan therefore comes first. The play is anchored by the Indigo Revolt of 1859 to 1860 in Bengal, which it dramatised; its English translation, published under James Long's name, led to Long's prosecution and imprisonment for libel, with Michael Madhusudan Dutt as the translator. That association with the indigo disturbances is the surest way to date it, since a play written about a revolt cannot precede the revolt.
• Option (d) is the closest competitor at 1863 and can be placed by remembering that Satyendranath Tagore, brother of Rabindranath, sat the examination in London within a few years of the Crown assuming direct government in 1858.
• Option (a) at 1875 is fixed by the standard cluster of reform bodies, the Arya Samaj in that year and the Prarthana Samaj in 1867.
• Option (c) at 1882 is fixed by Anandamath being a post revolt novel containing Vande Mataram, later adopted as the national song. Elimination route: the two literary works can be separated at once because Neeldarpan responds to an event of 1860 while Anandamath belongs to the 1880s, and once the field narrows to the 1860 and 1863 pair the answer follows.

Hence (b).

• Statement 1 is incorrect and it is the decisive statement, since statements 2 and 3 are readily accepted and the choice reduces to (b) against (d). Heavy extraction deepens and widens the channel and lowers the riverbed, which reduces the head of fresh water opposing the sea in the lower reaches and allows the saline wedge to travel further upstream. Salinity therefore increases rather than decreases, and this is a documented outcome on rivers with heavy mining near their mouths.
• Statement 2 is correct. The sand and gravel bed is itself a natural filter through which surface water percolates to the aquifer, and stripping it removes that filtration, exposing groundwater directly to surface contaminants; the mining operation adds its own load of oil and turbidity from machinery and haulage.
• Statement 3 is correct and follows from simple hydraulics. The river surface and the surrounding water table are hydraulically connected, so lowering the bed lowers the level at which the river stands, and the adjacent water table drains down towards it. Wells near the channel then fail, which is the effect most immediately felt by riparian communities. The wider consequences worth teaching are the undermining of bridge piers and embankments by bed degradation, the loss of the hyporheic zone and its invertebrate habitat, and the destruction of spawning substrate.

Hence (b).

• Statement 1 is incorrect and it is the only statement needed, since it appears in options (a), (c) and (d) and rejecting it leaves (b) at once. Organic matter increases water holding capacity rather than reducing it, and it does so in two ways: humus is colloidal and hydrophilic and holds several times its own weight in water, and organic matter binds mineral particles into stable aggregates, creating the pore structure in which water is retained against gravity. Raising soil organic carbon is the standard recommendation for drought resilience, which makes the statement not merely wrong but the reverse of settled practice.
• Statement 2 is incorrect. Soil is central to the sulphur cycle. The bulk of soil sulphur is held in organic matter and is released to the plant available sulphate form by microbial mineralisation, sulphur oxidising bacteria such as Thiobacillus convert reduced forms to sulphate, and under waterlogged and anaerobic conditions sulphate reducing bacteria run the reaction the other way to produce hydrogen sulphide. Sulphur deficiency in Indian soils, aggravated by the shift to high analysis fertilisers that carry no incidental sulphur, is a live agronomic problem.
• Statement 3 is correct. Irrigation water carries dissolved salts, and where drainage is poor and evaporation high the water leaves while the salts remain and accumulate in the root zone; a rising water table brought on by canal irrigation carries salts up by capillary action to the surface. The salinity and waterlogging of parts of the canal commands in Punjab, Haryana and western Uttar Pradesh is the standard Indian illustration.

Hence (b).

• Option (b) is correct. The Partnership for Action on Green Economy was launched in 2013 in response to the outcome document of the United Nations Conference on Sustainable Development held at Rio de Janeiro in 2012, known as Rio plus 20, whose text The Future We Want recognised the green economy in the context of sustainable development and poverty eradication as a means of achieving sustainable development. PAGE brings together five United Nations agencies, the Environment Programme, the International Labour Organization, the Development Programme, the Industrial Development Organization and the Institute for Training and Research, to support partner countries in reframing economic policy around sustainability. The elimination route is thematic rather than a matter of recalling the launch date. Green economy is the signature vocabulary of Rio plus 20, which is remembered for exactly two themes, the green economy and the institutional framework for sustainable development, the latter producing the High Level Political Forum.
• Option (a) is wrong because Johannesburg in 2002 is remembered for the Plan of Implementation and for type two partnerships rather than for the green economy, which had not yet entered the lexicon.
• Option (c) is wrong on a point of nomenclature as well as substance: the 2015 Paris meeting was the twenty first Conference of the Parties to the Framework Convention, and its output was the Paris Agreement on climate change, a treaty instrument rather than a green economy mechanism.
• Option (d) is wrong because the World Sustainable Development Summit is an annual conference convened by The Energy and Resources Institute in New Delhi, a national think tank event and not a United Nations conference at all.

Hence (b).

The key takes all five and the answer is (d).

• Statement 1 is correct: food printers extrude chocolate, sugar paste and dough layer by layer, and printed confectionery is an established niche in patisserie.
• Statement 2 is correct: the bionic ear demonstrated at Princeton in 2013 was printed from a hydrogel seeded with chondrocytes together with a silver nanoparticle coil, and is the standard cited example of printing a functional organ integrated with electronics.
• Statement 3 is correct: the automotive industry was among the earliest adopters, first for rapid prototyping of body panels and tooling and later for production of jigs, fixtures, brackets and low volume components.
• Statement 4 is correct and is now routine: patient specific titanium cranial and maxillofacial implants and surgical guides are printed from the patient's own computed tomography data, which is precisely the case additive manufacturing serves best, since every implant is a batch of one.
• Statement 5 is the doubtful one, and it survives on a permissive reading: printing is used to fabricate microfluidic devices, photonic and waveguide structures, heat sinks and interconnects, and printed electronics is a working field, so hardware used in data processing can be additively manufactured even though the printing of data processing itself is meaningless. Since no statement is rejected, only option (d) is available.

Hence (d).

• Statement 1 is correct. Barren Island is the only confirmed active volcano in South Asia and lies within Indian territory, in the Andaman Sea, on the volcanic arc produced by the subduction of the Indian plate beneath the Burma plate; the same arc carries Narcondam, which is classified as dormant.
• Statement 2 is incorrect on both the distance and the direction. Barren Island lies roughly 135 to 140 kilometres north east of Port Blair, which is in the Andaman group, whereas Great Nicobar is the southernmost island of the Nicobar group, several hundred kilometres to the south. The number in the statement is borrowed from the true distance and attached to the wrong reference point, which is the trap.
• Statement 3 is incorrect. After a long dormancy from 1803 the volcano resumed activity in 1991, but it has erupted repeatedly since, with episodes in 1994 and 1995, in 2005 following the great Sumatra Andaman earthquake, and again in 2017, when a National Institute of Oceanography vessel observed lava and ash emission at close quarters. Elimination route: statement 1 is standard and secure, which removes options (b) and (c); the choice between (a) and (d) then rests on statement 3, and a candidate who followed the 2017 reports rejects it directly.

Hence (a).

• Option (b) is correct. Prosopis juliflora, known in India as vilayati kikar, seemai karuvelam or ganda baval, is a thorny leguminous shrub or small tree native to Central and South America and introduced into India from the nineteenth century onward for fuelwood and for the afforestation of degraded and arid land. It has become one of the most damaging invasive alien species in the country. It reduces biodiversity by several reinforcing mechanisms: a deep taproot that draws down soil moisture and the water table beyond the reach of native species, dense thorny thickets that exclude both grazing and regeneration, allelopathic chemicals in leaf litter that suppress germination of neighbouring plants, and prolific seed set dispersed by livestock that eat the pods. Its spread across the Banni grasslands of Kachchh, into Keoladeo and into Tamil Nadu, where the Madras High Court ordered its removal, is the reason it recurs in the news.
• Options (a) and (c) are wrong and are constructed on a plausible sounding pattern, since many tree species do yield extracts used in cosmetics or as biopesticides, neem being the standard Indian example; Prosopis is not known for either use, and its economic value in India is as fuelwood and charcoal.
• Option (d) is wrong because option (b) is true. Governing principle: when a species appears in the news and the question offers one ecological effect against two commercial uses, the ecological effect is almost always the reason for the coverage.

Hence (b).

All three are correct and the answer is (d).

• Statement 1 is correct and follows from the physiology of the reef building corals, which depend on the symbiotic dinoflagellates in their tissues for the bulk of their energy. That symbiosis sets narrow requirements: water temperature broadly between twenty and thirty degrees Celsius, high light penetration and so shallow and clear water, normal salinity and low nutrient and sediment load. Those conditions are met between roughly thirty degrees north and thirty degrees south, and reefs are correspondingly absent from the cold upwelling coasts and from the mouths of large sediment laden rivers.
• Statement 2 is correct. Australia, Indonesia and the Philippines together account for over a third of the world's reef area, the last two lying within the Coral Triangle, which is the global centre of marine biodiversity, and the first holding the Great Barrier Reef.
• Statement 3 is correct and is the statement most often wrongly rejected. The comparison is by phylum rather than by species. Tropical rainforests hold far more species than reefs, but that diversity is concentrated within a few phyla, chiefly arthropods and chordates among animals. Reefs, being marine, host representatives of almost every animal phylum, since most animal phyla are exclusively or primarily marine, so a reef will carry sponges, cnidarians, flatworms, molluscs, annelids, arthropods, bryozoans, echinoderms, chordates and several minor phyla besides. The count usually quoted is around thirty two of the thirty four animal phyla on reefs against roughly nine in rainforests. Hence (d). Governing principle: species richness and phylum level disparity are different measures and can point in opposite directions.

• Option (c) is correct. Momentum for Change is an initiative of the secretariat of the United Nations Framework Convention on Climate Change, run to recognise and publicise practical climate solutions, and Climate Neutral Now is one of its focus areas, inviting individuals, companies and organisations to measure their emissions, reduce what they can and offset the remainder through certified emission reductions issued under the Clean Development Mechanism. The link to certified emission reductions is the surest identification, because those credits are instruments created under the Kyoto Protocol and administered through the Convention machinery, so only the Convention secretariat could build a pledge around them.
• Option (a) is wrong on function, and this is the discrimination worth carrying: the Intergovernmental Panel on Climate Change conducts no research and runs no programmes at all, its sole task being to assess published scientific literature and issue assessment and special reports. A body that does not implement cannot launch an implementation initiative.
• Option (b) is wrong because the United Nations Environment Programme is the broad environmental authority of the United Nations system and runs the Emissions Gap Report and much else, but the climate treaty machinery sits with the Convention secretariat, which is separately constituted at Bonn.
• Option (d) is wrong because the World Meteorological Organization is the specialised agency for weather, climate and hydrology, providing observation and monitoring, including the annual State of the Global Climate statement, rather than mitigation programmes.

Hence (c).

• Pair 1 is incorrectly matched. The Sanskrit College at Benaras was founded in 1791 by Jonathan Duncan, the Resident at Benaras, to cultivate Hindu law and learning and to supply the courts with qualified pandits. Sir William Jones was a judge of the Supreme Court at Calcutta and the founder in 1784 of the Asiatic Society of Bengal, and it is that association, together with his standing as the great Orientalist of the period, that makes his name plausible here.
• Pair 2 is correctly matched. The Calcutta Madrasa was established in 1781 by Warren Hastings for the study of Muslim law and Arabic and Persian learning, with the parallel purpose of producing officers competent in the law administered in the courts.
• Pair 3 is incorrectly matched, and this is the finest trap in the paper. Fort William College was founded at Calcutta in 1800 for the training of newly arrived civil servants in Indian languages, law and custom, and its founder was Richard Colley Wellesley, Marquess Wellesley, the Governor General. Arthur Wellesley was his younger brother, the soldier who commanded at Assaye and later became the Duke of Wellington, and he founded nothing of the kind. The surname is right and the given name is wrong, so a candidate who checks only the family name will accept the pair. Elimination route: rejecting pair 1 removes options (a) and (c), and accepting pair 2, which is standard, then settles the answer at (b) without the candidate ever having to resolve the Wellesley confusion.

Hence (b).

• Pair 1 is correctly matched. Catalonia is an autonomous community of Spain with Barcelona as its capital, and its unilateral independence referendum of October 2017 and the direct rule that followed under Article 155 of the Spanish Constitution are the reason it appeared in the news.
• Pair 2 is incorrectly matched. Crimea is a peninsula on the northern Black Sea, part of Ukraine and annexed by Russia in 2014; it has no connection with Hungary, which is landlocked.
• Pair 3 is correctly matched. Mindanao is the large southern island of the Philippines, the seat of the long Moro insurgency and of the Bangsamoro autonomy process, and the site of the siege of Marawi in 2017 after which martial law was imposed.
• Pair 4 is incorrectly matched. Oromia is the largest regional state of Ethiopia, home of the Oromo, whose protests from 2015 led to the resignation of the Prime Minister and the accession of Abiy Ahmed in April 2018. Nigeria's regions in the news are the north east under Boko Haram and the Niger Delta. Only pairs 1 and 3 are correct, so the answer is (c). The elimination is efficient: recognising Crimea as Ukrainian removes options (a) and (d), and recognising Oromia as Ethiopian removes (b), leaving (c) without any need to verify the two correct pairs.

Hence (c).

• Option (c) is correct and the stem itself supplies the route. Right to Life and Personal Liberty is the heading of Article 21, so the article named in the correct option must be Article 21, and only option (c) names it. In Justice K. S. Puttaswamy against Union of India, decided unanimously by nine judges in August 2017, the Court held that privacy is intrinsic to the life and personal liberty guaranteed by Article 21 and is also part of the freedoms guaranteed in Part III, overruling the contrary holdings in M. P. Sharma of 1954 and Kharak Singh of 1962. The second limb of the option matters: the Court did not locate privacy in Article 21 alone but found it distributed across Part III, arising from the freedoms of speech, movement and association in Article 19 and from the equality guarantee in Article 14 as well, which is why the phrase the freedoms guaranteed in Part III is the appropriate completion.
• Option (a) is wrong on both limbs, since Article 14 is equality before the law and the Forty second Amendment is remembered for inserting the words socialist and secular in the Preamble and for curtailing judicial review during the Emergency.
• Option (b) is wrong because Article 17 abolishes untouchability and the Directive Principles are expressly non justiciable, so they could not by themselves sustain an enforceable right.
• Option (d) is wrong because Article 24 prohibits the employment of children in hazardous work, and the Forty fourth Amendment is remembered for removing the right to property from Part III and for undoing several Emergency era changes.

Hence (c).

• Option (a) is correct. Pakhui, also spelt Pakke, lies in the East Kameng district of Arunachal Pradesh in the foothills of the Eastern Himalaya, bounded by the Kameng river on the west and the Pakke on the east. Declared a wildlife sanctuary and later a tiger reserve, it adjoins Nameri National Park across the Assam border, and the two together form a contiguous block of lowland and foothill forest. It is best known for its hornbills, four species occurring there, and for the Hornbill Nest Adoption Programme in which Nyishi tribal youth, once hunters of the birds for their casques, are employed to protect nest trees; the reserve won the India Biodiversity Award for that work.
• Options (b), (c) and (d) are wrong, and the useful correction is to attach one protected area to each of those States so that the confusion does not recur: Manipur has Keibul Lamjao, the only floating national park, on Loktak lake, home of the sangai; Meghalaya has Nokrek and Balpakram in the Garo hills; Nagaland has Intanki and the Fakim sanctuary. The reasoning aid for Arunachal Pradesh specifically is that its protected areas are named after the rivers that bound them, Pakke, Kameng, Dibang, Namdapha and Mouling, since the State's terrain is organised by the north to south river valleys descending from the Himalaya.

Hence (a).

• Statement 1 is correct and states the division of labour between the two vehicles accurately. The Polar Satellite Launch Vehicle is optimised for polar sun synchronous orbits at a few hundred kilometres, which is where remote sensing and Earth resources satellites belong, because a sun synchronous orbit crosses a given latitude at the same local solar time on every pass and so gives consistent illumination for comparing images across dates. The Geosynchronous Satellite Launch Vehicle, with its cryogenic upper stage, is built to place heavier payloads into geosynchronous transfer orbit, which is where communication satellites belong.
• Statement 2 is incorrect and follows directly from the first. Only a satellite in geostationary orbit, that is circular, equatorial and at about 35,786 kilometres where the orbital period matches the Earth's rotation, appears fixed in the sky. PSLV payloads are in low polar orbits with periods of roughly one hundred minutes, so they cross the sky rapidly and are visible from a given place only in short passes.
• Statement 3 is incorrect on the number of stages and on their arrangement. GSLV Mk III, now LVM3, is a three stage vehicle: two S200 solid strap on boosters, an L110 liquid core stage burning unsymmetrical dimethylhydrazine with nitrogen tetroxide, and the C25 cryogenic upper stage burning liquid hydrogen with liquid oxygen. There is no fourth stage. Elimination route: statement 2 is the cleanest reject, since the whole point of the geostationary orbit is that it is the only one giving a fixed apparent position, and rejecting it removes options (b) and (c); statement 1 is then secure and (a) follows.

Hence (a).

• Statement 2 is correct and is the more secure of the two. With effect from 1 April 2017 five remaining associate banks, the State Banks of Bikaner and Jaipur, Hyderabad, Mysore, Patiala and Travancore, together with the Bharatiya Mahila Bank, were merged into the State Bank of India, consolidating the group into a single entity and placing it among the fifty largest banks in the world by assets. The rationale advanced was scale, the removal of duplicated branches and treasury operations, and a single balance sheet capable of bearing the stressed asset burden.
• Statement 1 is incorrect on the word steadily. Capital infusion into public sector banks has moved erratically rather than in a rising line, tracking the recognition of stressed assets and the fiscal position of the year rather than following any trend; it fell in several years of the decade and then rose sharply with the recapitalisation package announced in October 2017, much of it delivered through recapitalisation bonds rather than budgetary transfers. The claim describes a monotonic increase where the actual pattern is lumpy and reactive. Since statement 2 stands and statement 1 falls, the answer is (b). Governing principle for statements of this shape: a word such as steadily converts a claim about magnitude into a claim about trend, and a trend claim is falsified by a single reversal, so such words should be treated as the weakest point of a statement rather than as filler.

• Item 1 is exempt. Cereal grains that are merely hulled, that is stripped of the outer husk without further processing or branding, fall at the nil rate, consistent with the general treatment of unbranded staple food grains as outside the tax so as not to burden basic consumption.
• Item 2 is exempt. Birds' eggs in shell, whether fresh, preserved or cooked, are at the nil rate, and the inclusion of cooked eggs in that entry is the counterintuitive part, since candidates assume that any processing attracts tax; boiling an egg in its shell does not take it out of the entry.
• Item 3 is not exempt. Fish that is processed and canned has undergone manufacture and packaging and is taxed, unlike fresh or chilled fish, which is at nil rate. The distinction between fresh produce and processed packaged food runs consistently through the schedules and is the single most useful principle for this question.
• Item 4 is exempt. Printed newspapers, journals and periodicals are at the nil rate, and the presence of advertising material in them does not alter that treatment, the exemption attaching to the newspaper as a whole; advertising services sold separately are of course taxable.
• Items 1, 2 and 4 being exempt and item 3 not, the answer is (c). Elimination route: recognising that canned processed fish is taxed removes options (b) and (d), and the choice between (a) and (c) then rests on the cooked eggs and newspapers entries. Rated Difficult because it requires specific schedule entries rather than a principle, and because the cooked egg entry defeats the obvious reasoning.

Hence (c).

• Statement 1 is correct. The expression Critical Wildlife Habitat is defined in section 2(b) of the Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006, not in the Wild Life (Protection) Act, and this placement is deliberate. The definition covers areas of national parks and sanctuaries required to be kept inviolate for wildlife conservation, and it is in the Forest Rights Act because the Act attaches conditions to any such determination: the process requires scientific and objective criteria, consultation and consent of the gram sabha, and the settlement of forest rights before any resettlement, and no resettlement may occur until a package is provided.
• Statement 2 is correct. The Baiga of Dindori district in Madhya Pradesh were the first community in India to be granted habitat rights, in 2016, under section 3(1)(e) of the Act, which recognises rights including community tenures of habitat and habitation for particularly vulnerable tribal groups and pre agricultural communities. Habitat rights are broader than rights over land or produce, extending to the customary territory and to the cultural and livelihood practices tied to it.
• Statement 3 is incorrect and it is the decisive statement. The process under the Forest Rights Act is bottom up and State administered: claims originate in the gram sabha, pass to the Sub Divisional Level Committee and then to the District Level Committee, and are approved by the State Level Monitoring Committee. The nodal ministry at the Centre is the Ministry of Tribal Affairs, not the Ministry of Environment, Forest and Climate Change, and no central ministry declares habitat rights. Elimination route: rejecting statement 3 removes options (b), (c) and (d) at once.

Hence (a).

All four disperse plant pathogens and the answer is (d).

• Item 1 is correct: birds carry spores, bacteria and viruses on feet, feathers and beak from plant to plant, transmit some pathogens through droppings, and create the wounds through which infection enters when they peck at fruit; they also carry infected insect vectors.
• Item 2 is correct: wind blown dust and soil particles carry fungal spores, bacteria, nematode cysts and resting structures over long distances, and abrasion by blown particles also injures leaf surfaces and opens entry points, which is why dust storms precede outbreaks in semi arid cropping systems.
• Item 3 is correct and operates by two distinct mechanisms: rain splash physically ejects spores and bacterial cells from infected tissue and soil onto healthy foliage above, which is the principal short range dispersal route for many bacterial blights and for anthracnose, and prolonged leaf wetness supplies the free water that spores need to germinate and penetrate.
• Item 4 is correct and is the most familiar route, wind carrying rust urediniospores across hundreds of kilometres, which is how wheat rusts move from one region to another between seasons. Since no item can be rejected, only option (d) survives and no elimination is needed. Governing principle: a plant pathogen is immobile and must be carried, so almost any agent that moves material between plants, whether animal, particle, water or air, is a potential means of dissemination.

Hence (d).

• Statement 1 is incorrect and it is the decisive statement. The National Programme for Organic Production is operated under the Ministry of Commerce and Industry, not the Ministry of Rural Development, and the reason is structural rather than accidental: the programme exists to provide accreditation and certification standards that are recognised by importing countries, so that Indian organic produce can be exported without recertification abroad. It is therefore an export facilitation instrument and belongs with the trade ministry. Domestic organic promotion runs on a separate track, through the Paramparagat Krishi Vikas Yojana under the Ministry of Agriculture and Farmers Welfare, which uses the participatory guarantee system rather than third party certification.
• Statement 2 is correct. The Agricultural and Processed Food Products Export Development Authority, a statutory body under the Ministry of Commerce, functions as the secretariat for the implementation of the programme, accrediting certification bodies and administering the India Organic mark, which follows directly from the export orientation just described.
• Statement 3 is correct. Sikkim was declared India's first fully organic State in January 2016, having phased out chemical fertilisers and pesticides across its cultivated area over roughly a decade; the achievement won the Future Policy Gold Award of the Food and Agriculture Organization in 2018. Elimination route: rejecting statement 1 removes options (a) and (d), and statement 3 is widely known, so the answer rests on APEDA.

Hence (b).
