2016

• Statement 1 is incorrect. Prorogation terminates a session of the House; it does not terminate the life of the House. Bills, notices, motions and resolutions pending before a House survive prorogation and are carried over to the next session. What causes a Bill to lapse is dissolution of the Lok Sabha, not prorogation of a session. The only casualties of prorogation are pending notices other than those for introducing Bills.
• Statement 2 is correct. Article 107(5) provides that a Bill pending in the Rajya Sabha which has not been passed by the Lok Sabha does not lapse on dissolution of the Lok Sabha. The logic is structural: the Rajya Sabha is a permanent House not subject to dissolution, so a Bill whose legislative journey is still entirely within that House is unaffected by the fate of the other House. By contrast, a Bill passed by the Lok Sabha and pending in the Rajya Sabha does lapse, because the Lok Sabha's own act of passage falls with the House. Since statement 1 is false and statement 2 is true, the answer is (b).
• Options (a) and (c) both require statement 1 to be true and fail on the prorogation-dissolution distinction; option (d) fails because Article 107(5) is express. The governing principle is that lapsing attaches to dissolution and to the stage the Bill has reached in each House, never to prorogation.

All three are indicators. From the 2015 edition onward the International Food Policy Research Institute computed the Global Hunger Index from four component indicators: the proportion of undernourished in the population, child wasting, child stunting and under-five mortality.

• Statement 1, undernourishment, is the calorie-deficiency measure drawn from FAO data and is the oldest component, carrying half the weight of the index.
• Statement 2, child stunting, is height-for-age deficiency and measures chronic undernutrition.
• Statement 3, child mortality, is the under-five mortality rate and captures the lethal consequences of undernutrition. Since none of the three can be excluded, the answer is (c).
• Options (a), (b) and (d) each require rejecting at least one genuine component. The elimination route is that a candidate who knows child mortality is a component can discard (a) and (b) at once, leaving (c) against (d), which turns only on whether stunting is included; since the index is explicitly built on both stunting and wasting, (c) follows.

A budget deficit is the excess of total expenditure over total receipts, so it narrows only if expenditure falls or receipts rise.

• Statement 1 is correct: revenue expenditure is the largest and most rigid block of government spending, and cutting it directly reduces the deficit.
• Statement 2 is incorrect: new welfare schemes add to expenditure and therefore widen the deficit, whatever their social merit.
• Statement 3 is correct: subsidies are a major component of revenue expenditure, and rationalising them, whether by better targeting or by trimming them, reduces outgo.
• Statement 4 is incorrect: import duty is a source of revenue receipts, so reducing it lowers receipts and widens the deficit. Hence 1 and 3, giving (c). The elimination route is immediate and decisive.
• Statement 2 is transparently expansionary, which kills (b) and (d) in one move, leaving (a) against (c); statement 3 is plainly a fiscal consolidation measure, so (c) follows. The governing principle is that any measure must be classified as either raising expenditure or reducing receipts before its effect on the deficit can be read off.

• Statement 1 is correct. The RBI guidelines of November 2014 expressly list non-bank prepaid instrument issuers, non-banking finance companies, telecom companies, supermarket chains, corporates, real sector cooperatives and public sector entities among those eligible to promote a payments bank, subject to the resident ownership and control condition.
• Statement 2 is incorrect and is the decisive statement. A payments bank may issue ATM and debit cards, but it is expressly barred from issuing credit cards, because a credit card is a lending instrument and lending is precisely what the licence excludes.
• Statement 3 is correct and states the defining restriction of the model: a payments bank accepts demand deposits up to the prescribed per-customer ceiling, deploys them in government securities and balances with scheduled commercial banks, and undertakes no lending. Since 1 and 3 are correct and 2 is not, the answer is (b).
• Options (a), (c) and (d) all require statement 2 to be true and are eliminated by the single principle that the payments bank is a deposit and payments vehicle, not a credit institution. That one principle also independently confirms statement 3, so a candidate who grasps the design can settle the question without recalling the promoter list.

• Statement 1 is correct. LiFi, or Light Fidelity, is visible light communication: data is encoded by modulating the intensity of an LED source at frequencies far above the flicker fusion threshold of the human eye, and recovered by a photodetector. The carrier is light rather than radio frequency electromagnetic radiation, which is the whole point of the technology.
• Statement 2 is also correct. LiFi is wireless, since no physical conductor carries the signal, and the visible light band offers roughly ten thousand times the spectral width of the radio frequency band, which is what permits the very high demonstrated data rates. Laboratory demonstrations before the paper had already reported speeds an order of magnitude above contemporary WiFi. Both statements being correct, the answer is (c).
• Option (d) is untenable once the name itself is decoded, and (a) and (b) each require rejecting one of two propositions that follow directly from the physics. The one nuance a candidate should hold is that LiFi requires line of sight and does not penetrate opaque barriers, but the statement claims only that it is wireless, which is true, so this limitation does not falsify it.

Intended Nationally Determined Contributions are the climate action pledges that parties to the UNFCCC submitted ahead of the Paris Conference of Parties in December 2015, setting out what each country intended to do to mitigate and adapt to climate change. The architecture was agreed at Warsaw in 2013 and Lima in 2014 and represents the shift from the top-down, negotiated targets of the Kyoto Protocol to a bottom-up, self-determined pledge system. On ratification of the Paris Agreement an INDC becomes a Nationally Determined Contribution, the word 'intended' falling away. Hence (b).

• Option (a) is a pure distractor built on the European refugee crisis then in the news and has no connection to the UNFCCC vocabulary.
• Option (c) misattributes the term to the Asian Infrastructure Investment Bank, whose members subscribe capital rather than submit contributions.
• Option (d) is the only serious distractor, since the Sustainable Development Goals were adopted in the same year and are also a global plan of action; it fails because the SDGs are a universal set of seventeen negotiated goals under the United Nations General Assembly, not individual country submissions, and there is no instrument called an INDC in the SDG framework. The discriminator is that an INDC is nationally determined and climate specific.

UDAY, the Ujwal DISCOM Assurance Yojana, was launched by the Ministry of Power in November 2015 to address the accumulated losses and unsustainable debt of State-owned power distribution companies. Its mechanism was that participating States took over seventy five per cent of discom debt over two years by issuing State bonds, with the balance restructured, coupled with operational commitments on aggregate technical and commercial losses, tariff revision and metering. The object throughout is the financial health of the distribution segment, so (d) is correct.

• Option (a) describes start-up support in renewable energy, which belongs to no part of UDAY.
• Option (b) describes household electrification, which was the object of the Deen Dayal Upadhyaya Gram Jyoti Yojana and later Saubhagya, and is the strongest distractor because it is also a power sector target of the same period; it fails because UDAY addresses the balance sheet of the distributor, not connection of the consumer.
• Option (c) describes fuel substitution in generation, which is generation-side policy and outside a distribution reform scheme altogether. The governing distinction is between generation, transmission and distribution: UDAY operates only on the last of the three.

• Statement 1 is correct. The International Finance Corporation is a member of the World Bank Group, the private sector lending arm, distinct from the IBRD and IDA which lend to governments. Describing it as an arm of the World Bank is accurate in the sense the question intends.
• Statement 2 is correct. Masala bonds are rupee-denominated bonds issued outside India, and their defining feature is that the currency risk sits with the investor rather than the issuer: the issuer raises and repays in rupees, so a depreciation of the rupee erodes the foreign investor's return and does not enlarge the issuer's liability. This is the opposite of conventional external commercial borrowing. They are available as a debt financing route to both public sector entities and private corporates, so the description in the statement holds. Both statements being correct, the answer is (c).
• Options (a) and (b) each require rejecting one true proposition and (d) rejects both. There is no clean elimination route here, since each statement must be known independently, which is what makes the item moderate rather than easy; the compensating help is that the name itself signals the rupee denomination.

• Statement 1 is correct. Vijayanagara land revenue was assessed on classified land, the rate varying with the quality and productivity of the soil and with whether the land was wet, dry or under orchard and plantation. Krishna Deva Raya's own Amuktamalyada advises the ruler on graded assessment, and the surviving revenue records show differential rates rather than a flat levy.
• Statement 2 is also correct. Vijayanagara drew revenue from a wide range of professional and commercial imposts beyond land revenue, including levies on artisans, traders, and the owners of workshops, the last of these described in the sources as an industries tax. The empire's fiscal base was notably broad, encompassing land revenue, tributes from feudatories, customs at ports and inland, professional taxes and judicial fines. Both statements being correct, the answer is (c).
• Options (a), (b) and (d) each require rejecting at least one true proposition. There is no elimination route: the two statements are independent, neither is intuitively false, and neither can be inferred from the other, so the candidate must know both. That is why the item is difficult despite concerning a much-taught reign.

The Sunga dynasty was founded by Pushyamitra Sunga, who displaced the last Mauryan ruler Brihadratha around 185 BCE. His son was Agnimitra, and Kalidasa's play Malavikagnimitra dramatises the love of Agnimitra, then viceroy at Vidisha, for Malavika, a princess of Vidarbha serving in the harem as an attendant. Hence (b).

• Option (a), Swapnavasavadatta, is by Bhasa and concerns Udayana of Vatsa and Vasavadatta, a much earlier and different legendary cycle.
• Option (c), Meghadoota, is Kalidasa's lyric poem in which an exiled yaksha sends a message to his beloved through a cloud; it is not a drama and has no historical protagonist.
• Option (d), Ratnavali, is attributed to Harshavardhana and again concerns Udayana, this time with Ratnavali of Ceylon. The elimination route runs through authorship and protagonist: Swapnavasavadatta and Ratnavali both belong to the Udayana cycle and can be discarded together, and Meghadoota is not a love story with a named dynastic prince, leaving only the play whose title itself couples Agnimitra with Malavika.

The boxes are the classification of domestic support to agriculture under the WTO Agreement on Agriculture. Amber box support is trade-distorting, being tied to prices or output, and is subject to reduction commitments measured by the Aggregate Measurement of Support. Blue box support is production-limiting direct payments, exempt from reduction because it is coupled to a requirement to restrict output. Green box support is minimally or non trade-distorting and is exempt without limit, covering research, extension, pest control, public stockholding for food security and decoupled income support. Hence (a).

• Option (b) fails because SAARC has no agricultural subsidy discipline of this kind.
• Option (c) is the most tempting distractor, since 'green' invites a climate association and the UNFCCC does use colour-coded vocabulary elsewhere, but the UNFCCC regulates emissions, not domestic farm support.
• Option (d) fails because the boxes are multilateral categories predating and independent of any bilateral free trade negotiation. The governing principle is that the vocabulary belongs to the discipline that classifies subsidies by their trade-distorting effect, which is a WTO function alone.

The capital budget comprises capital receipts and capital payments. Capital receipts are those that either create a liability or reduce a financial asset; capital payments are those that either create an asset or reduce a liability.

• Statement 1 is correct: expenditure on acquisition of roads, buildings and machinery creates physical assets and is classic capital expenditure.
• Statement 2 is correct: loans received from foreign governments create a liability of the Union and are therefore capital receipts, appearing in the capital budget as external debt.
• Statement 3 is correct: loans and advances granted to States and Union Territories create a financial asset in the hands of the Union and are capital expenditure, which is why their recovery appears on the receipts side as a capital receipt reducing that asset. All three being included, the answer is (d).
• Options (a), (b) and (c) each exclude at least one genuine item. The elimination route is the asset-liability test applied uniformly: a candidate who asks of each item only whether it creates or extinguishes an asset or a liability will include all three without needing to recall the budget document itself. The frequent error is to treat statement 2 as revenue because money is coming in, which confuses direction of flow with the nature of the transaction.

• Statement 1 is correct and reproduces the language of the Convention itself, which speaks of combating desertification and mitigating the effects of drought through effective action at all levels, supported by international cooperation and partnership arrangements.
• Statement 2 is incorrect and is the decisive statement. The UNCCD, adopted in 1994, has a particular focus on Africa, which is the subject of the first of its regional implementation annexes and was the region whose degradation drove the Convention's negotiation after the Sahel droughts. South Asia and North Africa are not the designated focus, and the Secretariat is in any event a facilitating body rather than a financing allocator, funding running through the Global Environment Facility and the Global Mechanism.
• Statement 3 is correct: the Convention is distinctive among the Rio instruments for its insistence on a bottom-up, participatory approach, requiring national action programmes to be prepared with the participation of local populations and non-governmental organisations. Hence 1 and 3, giving (c).
• Options (b) and (d) fall with statement 2, and (a) requires rejecting the participatory commitment which is one of the Convention's defining features. The elimination route is entirely through the geographical error in statement 2, which removes half the options at once.

• Statement 1 is correct. The International Monetary and Financial Committee is the advisory body of the IMF Board of Governors, meeting twice a year at the Spring and Annual Meetings. It has twenty four members mirroring the constituency structure of the Executive Board, operates by consensus without voting, and issues a communique advising the Fund on the management of the international monetary and financial system and on the direction of the Fund's work. It has no decision-making power, which is exactly what the word 'advises' captures.
• Statement 2 is also correct. A number of international institutions attend IMFC meetings as observers, and the World Bank is among them, alongside bodies such as the Financial Stability Board, the Bank for International Settlements, the OECD, the WTO and the United Nations. Both statements being correct, the answer is (c).
• Options (a), (b) and (d) each require rejecting a true proposition. There is no elimination route whatever: the two statements are independent institutional facts, neither derivable from the other, and the observer status of the World Bank appears in no standard preparation source. The item is therefore difficult in the exam hall even though it is easily verified afterwards.

• Statement 1 is correct. The Siddhas or Sittars of the Tamil country were a heterodox ascetic and mystical tradition, numbered conventionally at eighteen, who held to a single formless divine principle, rejected image worship and temple ritual, criticised caste and the authority of the Brahmana priesthood, and expressed themselves in vernacular Tamil verse. Their monotheism and their hostility to idolatry are the two features most often cited to distinguish them from the temple-centred bhakti of the Alvars and Nayanars.
• Statement 2 is also correct. The Lingayats or Virasaivas, founded in the Kannada region in the twelfth century and associated above all with Basava, rejected the caste hierarchy, opposed Brahmanical ritual and the authority of the Vedas, permitted widow remarriage, and questioned the doctrine of rebirth, a position visible in their burial rather than cremation of the dead, which presupposes union with Shiva at death rather than transmigration. Both statements being correct, the answer is (c).
• Options (a), (b) and (d) each require rejecting a true proposition. There is no elimination route, since the two traditions are independent and the specific doctrinal claims made about each go beyond the level at which the Siddhas in particular are usually taught. This is a difficult item honestly set.

Import cover expresses foreign exchange reserves in terms of time rather than money: it is the number of months of the country's imports that the existing stock of international reserves could finance at the prevailing rate of imports. It is the standard adequacy measure for reserves, the conventional prudential benchmark being three months, and it acquired particular resonance in India because reserves fell to roughly a fortnight's cover in the crisis of 1991. Hence (d).

• Option (a) describes the import-to-GDP ratio, a measure of openness, not of reserve adequacy.
• Option (b) is simply the import bill, an absolute flow with no reserve content at all.
• Option (c) describes the bilateral trade balance expressed as a ratio, which concerns the composition of trade between two partners rather than the sufficiency of reserves. The governing principle, and the elimination route, is that the word 'cover' denotes the capacity of a stock to meet a flow for a period, so only an option expressed in units of time can be right; (d) is the sole option denominated in months.

• Pair 1 is incorrectly matched and is the eliminating statement. The Kurds are an Iranian-language people of the mountainous region spanning south-eastern Turkey, northern Iraq, north-eastern Syria and north-western Iran, the largest stateless nation in West Asia, and they have no presence in or connection with Bangladesh.
• Pair 2 is correctly matched. The Madhesis are the plains-dwelling communities of Nepal's Terai, ethnically and linguistically close to the neighbouring Indian states, whose agitation over provincial demarcation, citizenship and representation under the constitution promulgated in September 2015 led to prolonged unrest and disruption of the India-Nepal border trade.
• Pair 3 is correctly matched. The Rohingya are a Muslim minority concentrated in Rakhine State in western Myanmar, denied citizenship under the 1982 law and subject to displacement on a large scale. Hence 2 and 3, giving (c). The elimination route is complete and immediate: the Kurd-Bangladesh pairing is wrong on geography alone, which removes (a); (b) and (d) then fail because both the remaining pairs are sound. Each of the three communities was in the news in the period before the paper, which is what made the item easy.

• Statement 1 is incorrect and is the eliminating statement. The OPCW, headquartered at The Hague, is the independent implementing body of the Chemical Weapons Convention of 1993, with a near-universal membership of States Parties and a relationship agreement with the United Nations. It is in no sense an organ of the European Union, and its mandate does not run through NATO or the WHO.
• Statement 2 is correct. Verification under the Convention extends beyond declared weapons stockpiles to the civilian chemical industry, through declarations and routine inspections of plants handling scheduled chemicals and certain discrete organic chemicals, precisely so that new weapons capability cannot emerge under commercial cover.
• Statement 3 is correct. Article X of the Convention obliges the Organisation to coordinate assistance and protection for States Parties threatened by or attacked with chemical weapons, and the OPCW maintains a voluntary fund and response arrangements for that purpose. Hence 2 and 3, giving (b). The elimination route is decisive and costs nothing: recognising that the OPCW is a global treaty body rather than a European institution removes (a), (c) and (d) together, leaving only (b) without any need to evaluate the other two statements independently.

• Statement 1 is incorrect. The farmer's share of premium under the scheme is not uniform across crops and seasons: it is capped at two per cent of the sum insured for kharif food and oilseed crops, one and a half per cent for rabi food and oilseed crops, and five per cent for annual commercial and horticultural crops, the balance of the actuarial premium being shared equally by the Centre and the State. The word 'uniform' and the phrase 'any crop in any season' are what make the statement false; a candidate who recalls only the two per cent figure will be caught by the qualifier.
• Statement 2 is correct. The scheme's coverage extends beyond standing crop losses to localised calamities and, distinctively, to post-harvest losses for a limited period after harvesting for crops kept in cut and spread condition in the field, where the loss arises from cyclone, cyclonic rain or unseasonal rain. This was one of the advertised improvements over the earlier insurance schemes. Hence (b).
• Options (a) and (c) fail on the uniformity claim and (d) fails because post-harvest cover is expressly provided. The governing lesson is that scheme questions are usually decided on the qualifier rather than on the headline number.

The Great Indian Hornbill is a large frugivorous bird of moist evergreen and semi-evergreen tropical forest, dependent on tall mature trees both for fruiting resources and for the large natural cavities in which the female seals herself during nesting. In India its stronghold is the Western Ghats, with a second population in the forests of the north-east and the Himalayan foothills. It is the state bird of Kerala and of Arunachal Pradesh, which is itself a useful memory anchor. Hence (d). The other three options fail on a single ecological principle applied consistently: each names a habitat that cannot support closed-canopy tall forest.

• Option (a), the sand deserts of the north-west, is arid scrub with no tall trees.
• Option (b), the higher Himalayas of Jammu and Kashmir, is temperate to alpine, above the altitudinal range of a tropical forest species.
• Option (c), the salt marshes of western Gujarat, is saline coastal wetland supporting waders and flamingos rather than canopy frugivores. The elimination route therefore requires no species-specific knowledge beyond recognising the bird as a large forest frugivore.

• Statement 1 is correct and states the conceptual innovation of the NGRBA, constituted in February 2009 under section 3 of the Environment (Protection) Act, 1986. Earlier Ganga Action Plans had treated pollution town by town and outfall by outfall; the Authority adopted the river basin as the unit of planning and management, which is the approach that allows upstream abstraction, tributary loading and cumulative flow to be addressed together.
• Statement 2 is correct: the Authority was the apex national body for conservation of the Ganga, with both regulatory and developmental functions, and it superseded the earlier institutional arrangements at the national level.
• Statement 3 is incorrect and is the decisive statement. The NGRBA was chaired by the Prime Minister; the Chief Ministers of the basin States were members, not rotating chairpersons. Hence 1 and 2, giving (a).
• Options (b), (c) and (d) all fail with statement 3. The elimination route is available on constitutional intuition alone: a national authority spanning several States and headed by a rotating State Chief Minister would be an anomaly in Indian administrative practice, where apex inter-State bodies are almost invariably chaired by the Prime Minister or a Union Minister.

Neem coating works through the nitrification-inhibiting action of neem's triterpenoids, chiefly azadirachtin and related limonoids, which suppress the ammonia-oxidising bacteria that convert ammonium to nitrate. The practical effect at field level is that urea hydrolyses and becomes plant-available more slowly, so nitrogen release is spread across the crop's uptake period rather than flushed in a pulse. That reduces leaching and volatilisation losses, raises nitrogen use efficiency and, incidentally, makes the urea unpalatable for diversion to industrial uses.

• Option (b) captures this and is correct.
• Option (a) inverts the mechanism: neem does not increase microbial nitrogen fixation, it inhibits nitrifying microorganisms, and in any event fixation converts atmospheric nitrogen and is irrelevant to applied urea.
• Option (c) is wrong on an absolute qualifier: slowing nitrification reduces nitrous oxide emissions from fertilised fields but cannot eliminate them, and 'not at all' is untenable for any agricultural practice.
• Option (d) is a straightforward fabrication, neem coating being neither a weedicide nor crop-specific. The elimination route is that (c) and (d) fail on their own terms without any knowledge of neem chemistry, leaving a choice between two microbiological claims of opposite sign.

• Statement 1 is incorrect. The Chief Secretary is the administrative head of the State secretariat and is selected by the Chief Minister, the appointment being made by the State Government. The office finds no mention in the Constitution and carries no gubernatorial appointment requirement, unlike the constitutional offices of Advocate General and Chairman of the State Public Service Commission, which the Governor does appoint. The recurring error is to assume that because the Governor is the formal executive head, senior administrative appointments run through the Governor's discretion; in practice such appointments follow the aid and advice of the Council of Ministers, and the choice of Chief Secretary is treated as the Chief Minister's prerogative.
• Statement 2 is also incorrect. The Chief Secretary has no fixed tenure; the incumbent holds office at the pleasure of the State Government and can be replaced at any time, which is why changes of government are so often followed by a change of Chief Secretary. Both statements being false, the answer is (d).
• Options (a), (b) and (c) each require accepting at least one of the two. The elimination route runs through statement 2: the absence of security of tenure for the office is well established, which removes (b) and (c) at once, leaving the question to turn on statement 1 alone.

• Statement 1 is correct and states the whole object of the scheme. Stand Up India requires every scheduled commercial bank branch to facilitate at least one loan between ten lakh and one crore rupees to at least one Scheduled Caste or Scheduled Tribe borrower and at least one woman borrower for setting up a greenfield enterprise in manufacturing, services or trading. The targeting is the design; it is not a general credit scheme with a reservation attached.
• Statement 2 is also correct. The scheme's architecture provided for a refinance window at the Small Industries Development Bank of India with an initial corpus of ten thousand crore rupees, alongside a credit guarantee mechanism, SIDBI being the designated refinancing institution for small enterprise credit. Both statements being correct, the answer is (c).
• Options (a), (b) and (d) each require rejecting one or both. There is no elimination route, since the two statements are independent, but statement 1 follows from the name and public framing of the scheme, so the item effectively turns on whether the candidate recalls SIDBI rather than NABARD or MUDRA as the refinancing agency.

• Statement 1 is incorrect and inverts the purpose of the programme. GIAHS, launched by the Food and Agriculture Organization in 2002, exists precisely to conserve traditional agricultural systems against displacement by modern high-input farming. Substituting modern technology and modern methods to maximise productivity would destroy the very system the designation is meant to safeguard.
• Statement 2 is correct and is a fair paraphrase of the FAO's own definition, which speaks of remarkable land use systems and landscapes rich in globally significant biological diversity, evolved from the co-adaptation of a community with its environment, and of safeguarding the associated agricultural biodiversity, knowledge systems and cultural landscape.
• Statement 3 is incorrect. Geographical Indication is a separate intellectual property regime administered nationally under TRIPS-compliant law; GIAHS designation carries no automatic GI status, and a blanket grant to all varieties of produce in a site would be inconsistent with how GI protection is applied for and examined. Hence (b). The elimination route is conceptual rather than factual: statements 1 and 3 both attribute to a heritage conservation programme functions belonging to an extension programme and to an intellectual property office respectively, and recognising that the word 'heritage' governs the whole design removes (a), (c) and (d) together.

• Statement 1 is correct and is the standard description. Core Banking Solutions place a bank's accounts on a centralised database accessed in real time by every branch, so that the customer's relationship is with the bank rather than with the branch of account. The practical consequences are anywhere banking, immediate credit of transfers, and the ability to run ATM, internet and mobile channels off a single ledger.
• Statement 2 is incorrect. Core banking is a bank's own technology platform adopted for operational efficiency and customer service; it is not a supervisory instrument and confers no additional control on the Reserve Bank, whose oversight operates through regulation, inspection and reporting requirements irrespective of the bank's software.
• Statement 3 is incorrect and describes something else entirely, namely amalgamation or resolution of a weak bank, which proceeds under section 45 of the Banking Regulation Act, 1949 and has no connection with core banking technology. Hence (a). The elimination route is straightforward: statements 2 and 3 are both plainly about supervision and resolution rather than about anything the word 'core banking' could denote, which removes (b), (c) and (d) at a stroke.

• Pair 1 is incorrectly matched. Annex I refers to the list of industrialised countries and economies in transition annexed to the United Nations Framework Convention on Climate Change of 1992, which bear differentiated commitments under the Convention and the Kyoto Protocol. The Cartagena Protocol, adopted in 2000 under the Convention on Biological Diversity, deals with the transboundary movement of living modified organisms and contains no such annex.
• Pair 2 is incorrectly matched. Certified Emission Reductions are the carbon credits generated by projects under the Clean Development Mechanism, which is a creature of the Kyoto Protocol. The Nagoya Protocol, adopted in 2010, also under the Convention on Biological Diversity, governs access to genetic resources and the fair and equitable sharing of benefits arising from their utilisation, and has nothing to do with emissions accounting.
• Pair 3 is correctly matched: the Clean Development Mechanism is established by Article 12 of the Kyoto Protocol as one of its three flexibility mechanisms, alongside Joint Implementation and Emissions Trading. Hence (c). The governing principle, and the cleanest elimination route, is that the two Protocols named in pairs 1 and 2 belong to the biodiversity regime while all three terms belong to the climate regime; a candidate who holds the CBD and UNFCCC families apart answers the question without evaluating any pair individually.

The suffix -ome denotes the complete complement of a class of molecules in a cell or organism: the genome is the full set of DNA, the proteome the full set of proteins, the metabolome the full set of metabolites. The transcriptome, correspondingly, is the full set of RNA transcripts, in the usual usage the messenger RNA molecules expressed by a cell, tissue or organism at a given time. Its scientific interest lies in the fact that unlike the genome, which is essentially fixed, the transcriptome varies with cell type, developmental stage and environmental condition, so it reports which genes are actually being expressed rather than which are merely present. Hence (b).

• Option (a) describes nucleases such as Cas9, ZFNs and TALENs, which belong to genome editing and are not a transcript population at all.
• Option (c) confuses the object with its explanation: a description of a mechanism is not a molecular complement.
• Option (d) describes mutagenesis, which concerns changes to the DNA sequence rather than the RNA output. The elimination route is entirely morphological: only one option names a complete set of molecules, which is what the -ome construction requires, so a candidate who parses the word correctly needs no bioinformatics.

Mission Indradhanush was launched by the Ministry of Health and Family Welfare in December 2014 to raise full immunisation coverage among children up to two years of age and among pregnant women, targeting districts with the largest numbers of partially immunised and unimmunised children. The name refers to the seven colours of the rainbow, standing for the vaccine-preventable diseases originally covered, diphtheria, whooping cough, tetanus, polio, tuberculosis, measles and hepatitis B, with further antigens added subsequently. Hence (a).

• Option (b) describes the Smart Cities Mission of the Ministry of Housing and Urban Affairs, launched in the same period, which is the strongest distractor purely because both are missions of the same government.
• Option (c) is an invention; there is no Indian exoplanet search programme of that name, and India's astronomy satellite of the period was AstroSat, which appears elsewhere in this paper.
• Option (d) refers to education policy, which was under review at the time but bears no such name. The item is easy because the name had been in continuous circulation for eighteen months before the paper.

• Statement 3 is correct and states the Mission's objectives. The National Mission for a Green India is one of the eight missions under the National Action Plan on Climate Change, approved in 2014, and aims at increasing forest and tree cover, improving the quality of degraded forest, enhancing ecosystem services including carbon sequestration, and improving forest-based livelihoods, framed explicitly as a combined adaptation and mitigation response.
• Statement 1 is incorrect: green accounting, the incorporation of environmental depletion and degradation into national and budgetary accounts, is a separate exercise associated with natural capital accounting and the work of expert groups on green national accounts, and forms no part of the Mission.
• Statement 2 is incorrect: a second green revolution is an agricultural production objective, addressed by agricultural missions, and the Green India Mission is not an agricultural programme, the word 'green' in its title referring to vegetation cover rather than to farm output. Hence (c). The elimination route is the name itself read correctly: a candidate who fixes on 'green' as forest cover discards both the accounting and the agricultural readings at once, removing (a), (b) and (d).

• Statement 1 is correct. The Regulations require a complete list of ingredients in descending order of composition by weight or volume at the time of manufacture, and additives must be declared by class name together with the specific name or the recognised international numerical identifier.
• Statement 2 is correct. Nutritional information is a mandatory declaration on the label, covering energy value and the amounts of protein, carbohydrate and fat per hundred grams or hundred millilitres or per serving.
• Statement 3 is incorrect and is the eliminating statement. Nothing in the Regulations requires a manufacturer to reproduce recommendations of the medical profession about possible allergic reactions; what the law imposes is a declaration of the ingredients themselves, from which an allergic consumer may draw the inference, and any medical advisory would in any event be a matter for professional bodies rather than a labelling obligation.
• Statement 4 is correct and is distinctively Indian: the green filled circle in a green square for vegetarian food and the corresponding brown or red mark for non-vegetarian food are mandatory on the principal display panel. Hence 1, 2 and 4, giving (c).
• Statement 3 is implausible on its face, which removes (a) and (b) at once, leaving (c) against (d) to turn on the nutrition declaration alone.

Net metering is the billing arrangement that makes small rooftop solar viable for a consumer. A bidirectional meter records both the electricity drawn from the grid and the surplus exported to it, and the consumer is billed only on the net drawal over the settlement period, so the grid functions in effect as a store for daytime surplus generation. Without it, a household would have to consume its generation instantaneously or invest in batteries, and the economics of rooftop solar would collapse. Hence (a).

• Option (b) concerns piped natural gas distribution, which is metered conventionally in one direction only and involves no export by the consumer.
• Option (c) concerns compressed natural gas retrofitting of vehicles, which has no metering dimension at all.
• Option (d) concerns water metering, which again is unidirectional. The governing principle, and a complete elimination route, is that the word 'net' presupposes flow in two directions and therefore a consumer who is also a producer; only rooftop solar creates that condition among the four options.

The Ease of Doing Business Index was published by the World Bank in its annual Doing Business report, which scored economies on indicators such as starting a business, dealing with construction permits, getting electricity, registering property, getting credit, paying taxes, trading across borders, enforcing contracts and resolving insolvency. Hence (c).

• Option (a) is wrong: the OECD publishes a large body of comparative economic work but not this index.
• Option (b) is the strongest distractor, since the World Economic Forum publishes the Global Competitiveness Index, which is a superficially similar country ranking on business environment; the discriminator is that the Doing Business methodology measured regulatory procedures against a standardised hypothetical firm in the largest business city, whereas the Global Competitiveness Index rested substantially on an executive opinion survey.
• Option (d) is wrong: the WTO administers trade agreements and does not rank domestic regulatory environments. The item is easy because the ranking was a standing item of Indian economic news throughout the period.

The Banjaras were the itinerant carrying and trading community of medieval India, moving in large caravans known as tandas with pack bullocks numbering in the thousands, and carrying bulk goods, above all foodgrain and salt, over long distances between producing regions, markets and armies on campaign. Contemporary observers including Peter Mundy remarked on the scale of their caravans, and Mughal military logistics depended heavily on them for grain supply. Hence (d).

• Option (a) is wrong because the community was defined by mobility rather than by cultivation, though sections settled to agriculture in later centuries.
• Option (b) is wrong: they served armies as suppliers, not as combatants, and their commercial neutrality was precisely what allowed them to trade with opposing forces.
• Option (c) is wrong: weaving in medieval India was the occupation of distinct artisanal castes such as the julahas, koris and salis. The organising principle is that medieval Indian trade divided broadly between the sedentary financing and wholesale merchants and the itinerant carrying communities, and the Banjaras are the paradigm of the second.

James Prinsep, an assay master of the East India Company's mint and secretary of the Asiatic Society of Bengal, deciphered the Brahmi script in 1837, which unlocked the Ashokan edicts. The immediate historical consequence was substantial: the inscriptions name their author only as Devanampiya Piyadassi, and it was the correlation of that title with the Sri Lankan chronicles, the Dipavamsa and Mahavamsa, that identified him as Ashoka and restored the Mauryan emperor to Indian history. Hence (b).

• Option (a), Georg Bühler, was a distinguished epigraphist and Indologist who worked extensively on Indian palaeography, but he came a generation later and built on Prinsep's decipherment.
• Option (c), Max Müller, was a philologist and Sanskritist known for editing the Rig Veda and the Sacred Books of the East, not an epigraphist.
• Option (d), William Jones, founded the Asiatic Society in 1784 and established the relationship between Sanskrit, Greek and Latin, but died in 1794, four decades before the decipherment. The chronological route alone eliminates Jones, and the association of Prinsep with Brahmi and Kharosthi settles the rest.

• Statement 1 is incorrect. The Gram Nyayalayas Act, 2008 confers both civil and criminal jurisdiction on these courts. Each Gram Nyayalaya is presided over by a Nyayadhikari holding the rank of a judicial magistrate of the first class, and the schedules to the Act specify the criminal offences triable and the civil disputes cognisable, the criminal jurisdiction covering offences punishable with up to two years' imprisonment. Restricting them to civil matters would defeat the object of taking justice to the doorstep of rural litigants, most of whose disputes are petty criminal as much as civil.
• Statement 2 is correct. The Act directs the Gram Nyayalaya to make efforts at conciliation and settlement, and provides for the appointment of conciliators for that purpose, drawn from persons of repute in the locality, which is what the statement describes as local social activists acting as mediators or reconciliators. Hence (b).
• Options (a) and (c) fail on the civil-only claim, and (d) fails because the conciliation machinery is express in the statute. The eliminating consideration is that the Nyayadhikari holds magisterial rank, which is a criminal judicial office, so a purely civil jurisdiction would be inconsistent with the design of the court itself.

• Statement 1 is incorrect. The Trans-Pacific Partnership, signed in February 2016, had twelve parties: the United States, Japan, Australia, New Zealand, Canada, Mexico, Chile, Peru, Singapore, Malaysia, Vietnam and Brunei. That is far from all Pacific Rim countries; Indonesia, the Philippines, Thailand, South Korea, Colombia and Ecuador, among others, were not parties, so the claim is defeated many times over quite apart from the position of China and Russia.
• Statement 2 is incorrect and is the more clearly wrong of the two. The TPP was a comprehensive trade and investment agreement covering tariff elimination, services, investment protection, government procurement, intellectual property, labour standards, environmental provisions and state-owned enterprises. It was not a security arrangement, and the word 'only' makes the statement indefensible even on the loosest reading of its strategic significance in the Asia-Pacific. Both statements being false, the answer is (d).
• Options (a), (b) and (c) each require accepting one of them.

• Statement 1 is correct. The India-Africa Forum Summit met first at New Delhi in 2008, second at Addis Ababa in 2011, and third at New Delhi in October 2015, the last being the largest gathering of foreign leaders hosted by India since the Non-Aligned Movement summit of 1983 and the first to which all fifty four African countries were invited rather than a representative selection chosen through the African Union.
• Statement 2 is incorrect. The summit format was instituted in 2008 as part of a deliberate expansion of India's Africa engagement, partly in response to China's Forum on China-Africa Cooperation launched in 2000. Nehru's engagement with Africa was real but ran through anti-colonial solidarity, the Bandung Conference of 1955 and the Non-Aligned Movement, not through any summit series begun in 1951. Hence (a).
• Options (b) and (c) require accepting the Nehru attribution, and (d) requires rejecting the sequence, which was widely reported. The date in statement 2 is the tell: 1951 precedes the independence of almost every African state, so there was no set of sovereign African counterparts with whom to hold a summit.

Both statements are correct and together reproduce the stated objectives of the framework.

• Statement 1 is correct: the MCLR guidelines, effective from April 2016, prescribe a formula-based computation from the marginal cost of funds, the negative carry on the cash reserve ratio, operating costs and a tenor premium, and require banks to publish rates for stated tenors, which is precisely a transparency requirement replacing the discretion that characterised the base rate and, before it, the benchmark prime lending rate.
• Statement 2 is correct: the substantive purpose was to improve monetary transmission. Under the base rate system, computed on average cost of funds, a reduction in the policy repo rate reached borrowers slowly, because the average cost of a bank's existing deposit book moves only as deposits reprice. Anchoring lending rates to the marginal cost forces the incremental cost of funds, which responds to the policy rate, into the lending rate, so cuts pass through faster while banks' margins remain protected. That is fairness to borrower and bank alike. Hence (c).
• Options (a), (b) and (d) each reject a stated purpose. The item is fair because both statements read as unobjectionable regulatory intentions, and neither contains a trap qualifier.

• Statement 1 is correct. The Kharai, found in the Kachchh region of Gujarat, is the only camel breed in the world adapted to swim, crossing creeks in the Gulf of Kachchh to reach mangrove islands, distances of around three kilometres being routinely reported.
• Statement 2 is correct and is the ecological basis of that behaviour: the breed browses on mangrove, principally Avicennia marina, and derives both nutrition and much of its water requirement from the saline foliage, which is why its distribution tracks the mangrove creeks so closely.
• Statement 3 is incorrect and is the eliminating statement. The Kharai is a domesticated breed, herded by the Jat and Rabari pastoralist communities of Kachchh, and its formal recognition as a registered breed by the National Bureau of Animal Genetic Resources presupposes domestication, since the register is of domestic animal genetic resources. Hence 1 and 2, giving (a).
• Options (b), (c) and (d) all fail with statement 3. The elimination route is available without any specific knowledge of the animal: the stem itself calls it a breed, and a breed is by definition the product of selective domestication, so statement 3 is self-contradictory with the question as framed.

INS Astradharini, commissioned in October 2015, is a torpedo launch and recovery vessel, indigenously designed and built to support the trials of underwater weapons and sonar systems developed by the Naval Science and Technological Laboratory at Visakhapatnam. She replaced the older Astravahini and is notable for a catamaran hull form that gives stability during launch and recovery operations. Hence (c).

• Option (a) is wrong: amphibious warfare ships of the Indian Navy are the landing platform dock and landing ship tank classes, of which INS Jalashwa is the best known.
• Option (b) is wrong: India's nuclear-powered submarines are the Arihant class and the leased Chakra, and a trials support vessel is not a submarine at all.
• Option (d) is wrong for a further reason worth stating plainly, that India has never operated a nuclear-powered aircraft carrier; Vikramaditya and the later Vikrant are conventionally powered. The name itself supplies a partial route, astra denoting a weapon and dharini a bearer or holder, which points to a weapon-carrying auxiliary rather than a combatant.

Greased Lightning-10 is a battery-powered, remotely piloted tilt-wing demonstrator built at NASA's Langley Research Center, with ten electric motors distributed along the wing and tail. Its significance is that it achieved the full transition from vertical take-off, in the manner of a helicopter, to efficient horizontal wing-borne flight, which is the hard problem in distributed electric propulsion and the technical ancestor of the urban air mobility designs that followed. Hence (a).

• Option (b) is a distractor built on solar aviation, the salient project of the period being Solar Impulse 2, which was Swiss rather than Japanese and was circumnavigating the globe while this paper was set.
• Option (c) misattributes it to Chinese space astronomy.
• Option (d) is the most tempting for an Indian candidate, since ISRO flew its Reusable Launch Vehicle Technology Demonstrator in May 2016, weeks before the exam, but that vehicle carried no such name. The elimination route is weak; the item rewards having read the specific report.

• Statement 1 is correct. The initiative, taken up under the Rashtriya Krishi Vikas Yojana, was built on cluster demonstrations covering improved production practices, post-harvest processing and value addition for the nutri-cereals, on the reasoning that millet consumption had declined partly because processing and palatability constraints were never addressed alongside production.
• Statement 2 is correct. Millets are grown predominantly on rainfed, marginal and low-fertility land in dryland regions, and the cultivating households are disproportionately small, marginal and tribal, so those are the farmers with the larger stake in any millet programme.
• Statement 3 is incorrect and is the decisive statement. The initiative works with existing millet growers to raise productivity and returns; it does not seek to pull commercial crop farmers out of their crops with free input kits, and an inducement of that kind would sit oddly with a nutrition security objective focused on rainfed regions. Hence 1 and 2, giving (c). The elimination route runs through the implausibility of statement 3, which removes (b) and (d), after which statement 2 follows from the agro-ecology of millets without any scheme-specific knowledge, giving (c) over (a).

Swadeshi and boycott were adopted as formal methods of struggle during the anti-partition agitation in Bengal that followed Curzon's announcement of 1905, the boycott resolution being passed at the Calcutta Town Hall meeting of 7 August 1905 and the movement running to 1908. The two were complements: boycott of British goods created the demand that swadeshi enterprise was to meet, and the campaign extended beyond goods to schools, courts and titles. Hence (a).

• Option (b) is wrong on chronology, the Home Rule Leagues dating from 1916.
• Option (c) is wrong for the same reason and is the strongest distractor, since non-cooperation from 1920 used boycott on a far larger scale; the question asks for the first adoption, not the fullest use, and this is the discriminator on which the item turns.
• Option (d) is wrong: the Simon Commission of 1927-28 was met with boycott of the Commission itself, which is a later and different application. A candidate need only order the four events chronologically, since the earliest of them is the answer to any question phrased as a first adoption.

• Statement 1 is incorrect and is the eliminating statement. The Bodhisattva ideal is central to Mahayana, not Hinayana. The Hinayana or Theravada path holds up the arhat, who attains nirvana through individual discipline and insight and does not remain to ferry others across; the term bodhisattva does appear in the earlier tradition, but confined to the previous lives of Gautama himself, not as a general ideal open to all practitioners.
• Statement 2 is correct: the Bodhisattva is defined by karuna, compassion, joined to the aspiration for bodhi, and is one who has generated the awakening mind but has not yet attained full Buddhahood, hence 'on his way to enlightenment'.
• Statement 3 is correct and states the vow that distinguishes the ideal: the Bodhisattva postpones final nirvana in order to work for the liberation of all sentient beings, Avalokiteshvara, Manjushri and Maitreya being the best known figures. Hence 2 and 3, giving (b).
• Options (a), (c) and (d) all fail: (a) and (d) accept the Hinayana attribution, and (c) rejects the self-postponement vow which is the very content of the ideal. Recognising the Mahayana attribution alone settles the question.

Medecins Sans Frontieres, founded in Paris in 1971 by a group of doctors and journalists who had worked in the Biafran war, is an independent international non-governmental organisation providing medical humanitarian assistance in conflict zones, epidemics and disasters. Its defining characteristics are independence from any government or intergovernmental body, the great bulk of its funding coming from private individual donors, and temoignage, the practice of speaking publicly about what its staff witness, which would be impossible for an agency answerable to states. It received the Nobel Peace Prize in 1999. Hence (b).

• Option (a) is wrong: the WHO is the United Nations specialised agency for health and has no such operational division; MSF frequently criticises WHO responses, which it could not do as a division of it.
• Option (c) is wrong on both limbs, MSF being neither intergovernmental nor sponsored by the European Union, though it receives some institutional funding from European donors.
• Option (d) is wrong for the same structural reason as (a). The governing principle is that the organisation's independence from states is not incidental but constitutive of what it is, so every option asserting a governmental or intergovernmental character fails at once.

• Statement 1 is incorrect and is the eliminating statement. TEEB was launched in 2007 following a proposal by the G8 plus 5 environment ministers at Potsdam, and is hosted by the United Nations Environment Programme alone, with support from a range of donor governments and the European Commission. Neither the International Monetary Fund nor the World Economic Forum hosts it, and the inclusion of the IMF in particular should read as implausible, that institution having no biodiversity mandate.
• Statement 2 is correct: the whole purpose of the study, led by Pavan Sukhdev, was to make the economic value of biodiversity and ecosystem services visible, on the reasoning that what is not priced is treated as free and is therefore depleted.
• Statement 3 is correct and reproduces the initiative's own three-step formulation, recognise value, demonstrate value, capture value, the last referring to instruments such as payments for ecosystem services, reformed subsidies and natural capital accounting that convert recognised value into changed incentives. Hence 2 and 3, giving (c).
• Options (a) and (d) fall with statement 1, and (b) requires rejecting statement 2, which is simply a restatement of the initiative's name.

• Statement 1 is correct. Pterocarpus santalinus, red sanders or red sandalwood, is endemic to a restricted tract of the Eastern Ghats in Andhra Pradesh, principally the Seshachalam, Veligonda, Lankamalla and Palakonda hills across Chittoor, Kadapa, Kurnool and Nellore. That narrow endemism, combined with the value of the timber in East Asian markets, is precisely what drives the smuggling that keeps it in the news.
• Statement 2 is incorrect and turns on habitat. Red sanders is a species of dry deciduous forest on rocky, degraded, red lateritic soils in a rain-shadow tract receiving modest rainfall; it is not a rain forest species at all, and the tropical rain forests of South India, the Western Ghats evergreen belt, are a different ecological world with an entirely different assemblage. The species is also not the dominant or most important tree even within its own formation. Hence (a).
• Options (b) and (c) require accepting the rain forest attribution, and (d) requires denying its South Indian occurrence, which the news reports themselves establish. The trap is the assumption that a valuable, threatened South Indian timber species must be a rain forest tree; the discriminator is that red sanders is a dry-tract endemic, and confusing it with Santalum album, sandalwood, compounds the error.

REDD+ is the UNFCCC mechanism for Reducing Emissions from Deforestation and forest Degradation, with the plus denoting conservation of forest carbon stocks, sustainable management of forests and enhancement of forest carbon stocks. All three propositions follow from a well-designed scheme.

• Statement 1 is correct: forest cover retained for carbon is forest cover retained for the species it houses, and the Cancun safeguards expressly require that REDD+ actions be consistent with the conservation of natural forests and biological diversity and not be used to convert natural forest to plantation.
• Statement 2 is correct: reduced degradation and improved forest management raise the structural and functional resilience of the ecosystem to fire, drought and pest outbreak.
• Statement 3 is correct: REDD+ is built on results-based payments to the countries and communities that forgo deforestation, and community participation and benefit sharing are integral to the design, so income accrues to forest-dependent populations who are among the poorest. Hence (d).
• Options (a), (b) and (c) each exclude a genuine co-benefit. The elimination route is the framing of the stem itself: it asks what proper design and effective implementation can contribute, which is a question about potential rather than record, and on that framing no listed co-benefit can be excluded.

The Greenhouse Gas Protocol is a carbon accounting standard, developed jointly by the World Resources Institute and the World Business Council for Sustainable Development, which sets out how an entity should measure and report its emissions. Its best known contribution is the division of emissions into Scope 1, direct emissions from owned or controlled sources, Scope 2, indirect emissions from purchased electricity, heat or steam, and Scope 3, all other indirect emissions across the value chain. It is a measurement framework, not a treaty and not a funding mechanism, and it underpins most corporate emissions disclosure worldwide. Hence (a).

• Option (b) describes something closer to the Green Climate Fund or the Clean Development Mechanism, both of which move money, whereas the Protocol moves only method.
• Option (c) fails on three independent grounds: it is not intergovernmental, it has not been ratified by anyone, and no instrument sets a universal target for 2022.
• Option (d) misattributes it to the forest carbon family hosted by the World Bank, such as the Forest Carbon Partnership Facility. The elimination route is the word 'protocol' read against the options: a candidate who notices that only one option describes a method of counting rather than a mechanism of paying or a commitment to cutting will reach (a) without knowing the sponsoring institutions.

• Statement 1 is incorrect and is the eliminating statement. The Financial Stability and Development Council was constituted in December 2010 by the Government of India on the recommendation of the Raghuram Rajan Committee on Financial Sector Reforms, and functions under the Department of Economic Affairs in the Ministry of Finance. It has no relationship with NITI Aayog, which was in any case created only in 2015, four years later, and is a policy think tank rather than a financial regulator.
• Statement 2 is correct: the Council is chaired by the Union Finance Minister, with the Governor of the Reserve Bank, the heads of SEBI, IRDAI, PFRDA and IBBI, the Finance Secretary and other senior officials as members.
• Statement 3 is correct and states its principal function: the Council was created to deal with macroprudential supervision of the economy, including the functioning of large financial conglomerates, and to coordinate among regulators where systemic risk crosses sectoral boundaries, a gap exposed by the global financial crisis. Hence 2 and 3, giving (c).
• Options (a) and (d) fall with statement 1, and (b) requires rejecting the Finance Minister's chairmanship, which follows from the body's location in the Ministry of Finance. The chronological impossibility in statement 1 is the cheapest route to the answer.

• Statement 1 is correct. Agenda 21 is a comprehensive, non-binding action plan for sustainable development in the twenty first century, organised in forty chapters across four sections covering social and economic dimensions, conservation and management of resources, strengthening the role of major groups, and means of implementation. Its most durable legacy is Local Agenda 21, which pushed implementation down to municipal government.
• Statement 2 is incorrect and turns on a single date. Agenda 21 was adopted at the United Nations Conference on Environment and Development, the Earth Summit, at Rio de Janeiro in June 1992, alongside the Rio Declaration, the Forest Principles, the UNFCCC and the Convention on Biological Diversity. The Johannesburg summit of 2002 was the ten year review, which produced the Johannesburg Plan of Implementation and reaffirmed Agenda 21 rather than originating it. Hence (a).
• Options (b) and (c) require accepting the Johannesburg attribution, and (d) requires denying the plainest fact about the document. The organising principle worth teaching is the sequence Stockholm 1972, Rio 1992, Johannesburg 2002, Rio plus 20 in 2012, which resolves a large family of questions of this kind; the numeral 21 in the title refers to the twenty first century, which itself signals a document drafted before 2000.

The Satyashodhak Samaj, the Truth Seekers' Society, was founded by Jyotirao Phule at Pune in 1873. Its object was the liberation of the shudras and atishudras from Brahmanical dominance: it rejected the necessity of Brahmana priests, instituted marriage and other ceremonies conducted without them, campaigned against caste discrimination and untouchability, and promoted education for lower castes and for women, Phule and Savitribai Phule having opened schools for girls from the late 1840s. It is therefore an anti-caste movement in Maharashtra, giving (c).

• Option (a) misplaces it as tribal upliftment in Bihar, which describes a different set of movements altogether.
• Option (b) misplaces it as a temple-entry movement in Gujarat; temple entry as a distinct campaign belongs chiefly to Kerala and to the Vaikom and Guruvayur satyagrahas, and in any case the Samaj's thrust was against priestly mediation rather than for admission to temples.
• Option (d) misplaces it as a Punjab peasant movement. The item is decided by geography alone once Phule is correctly located in the Bombay Presidency.

All three are correct.

• Statement 1: viruses infecting bacteria are bacteriophages, among the best studied entities in molecular biology; T4, lambda and M13 are standard laboratory organisms, and phage biology gave us restriction enzymes and, more recently, the CRISPR system, which is a bacterial defence against phage.
• Statement 2: viruses infecting fungi are mycoviruses, mostly double-stranded RNA viruses transmitted by hyphal anastomosis and sporulation rather than by an extracellular route; the best known is the hypovirus of Cryphonectria parasitica, which attenuates the virulence of the chestnut blight fungus and has been used as a biocontrol agent.
• Statement 3: plant viruses are numerous and agriculturally serious, tobacco mosaic virus being the first virus ever characterised, and the group includes cassava mosaic, banana bunchy top and the geminiviruses. Hence (d).
• Options (a), (b) and (c) each exclude a genuine host group. The governing principle, and the elimination route for a candidate who has never met a mycovirus, is that viruses are obligate intracellular parasites of cells as such, and there is no reason in principle why any cellular life form should be exempt; archaea have their own viruses too. Fungi are the only statement likely to give pause, so the item is moderate rather than easy.

Base Erosion and Profit Shifting refers to the strategies by which multinational enterprises exploit gaps and mismatches between national tax systems to shift profits away from the jurisdictions where economic activity and value creation occur and into low or no-tax jurisdictions, thereby eroding the tax base of the former. The techniques include transfer mispricing, excessive intra-group debt, treaty shopping through conduit jurisdictions and the artificial avoidance of permanent establishment status. The OECD and G20 fifteen-point action plan, finalised in October 2015, was the coordinated response. Hence (b).

• Option (a) describes extractive industry conduct, which is a different grievance about multinationals and has no tax content.
• Option (c) describes biopiracy and the access and benefit sharing questions governed by the Nagoya Protocol.
• Option (d) describes the externalities critique of project appraisal. The elimination route is the vocabulary: 'base' in this phrase can only be the tax base, so the three options with no fiscal content fall away together, and the candidate need not know the OECD project at all.

• Statement 2 is correct and states the sole statutory purpose. Section 9B, inserted by the Mines and Minerals (Development and Regulation) Amendment Act, 2015, requires the State Government to establish a District Mineral Foundation as a trust in every district affected by mining, for the interest and benefit of persons and areas affected by mining-related operations. It is funded by contributions from lease holders, a proportion of royalty fixed by the Central Government, and its funds are deployed through the Pradhan Mantri Khanij Kshetra Kalyan Yojana on drinking water, sanitation, health, education, environment and livelihoods in the affected areas.
• Statement 1 is incorrect and is the decisive statement: exploration is promoted through a wholly separate instrument, the National Mineral Exploration Trust created by section 9C of the same amendment, and the two trusts must not be confused.
• Statement 3 is incorrect: the power of State Governments to grant mineral concessions derives from the MMDR Act itself and, after 2015, operates through auction; a district-level trust cannot authorise a State Government to do anything, the proposition inverting the administrative hierarchy. Hence (b). The elimination route is that statement 3 is structurally absurd, which removes (c) and (d), leaving the item to turn on the distinction between the two trusts created by the same amendment.

SWAYAM, Study Webs of Active Learning for Young Aspiring Minds, is the Government of India's massive open online course platform, hosting courses from the ninth standard through to post-graduation, prepared by faculty across the country and delivered free of cost, with a nominal fee only for proctored examination and certification. It is complemented by the SWAYAM Prabha direct-to-home educational television channels. The aim as stated in option (d), affordable and quality education to citizens for free, is therefore correct.

• Option (a) describes the self help group and rural livelihoods architecture, which runs through the National Rural Livelihoods Mission.
• Option (b) describes start-up support under Startup India and the Fund of Funds.
• Option (c) describes the adolescent girls programmes, SABLA and later schemes under the umbrella of women and child development. The name itself supplies a partial route for a candidate who recalls the expansion, since the words 'active learning' and 'young aspiring minds' point unmistakably to education, and the acronym is the government's own, which is why the item sits at moderate rather than difficult.

• Statement 1 is incorrect. The Ajanta caves were excavated in two distinct phases, an earlier Hinayana phase from about the second century BCE and a later Mahayana phase under Vakataka patronage in the fifth century CE. Mahabalipuram is a Pallava foundation of the seventh and eighth centuries CE, principally under Narasimhavarman I and Rajasimha. The two sites do not share a period on any reading.
• Statement 2 is incorrect. Ajanta is Buddhist throughout, its caves comprising chaityas and viharas with painting and sculpture on Buddhist themes. Mahabalipuram is Brahmanical, its rathas, mandapas and the Shore Temple dedicated to Shiva, Vishnu and Durga, with the great open air relief usually read as the Descent of the Ganga or Arjuna's Penance.
• Statement 3 is correct and is the only shared feature: both sites carry rock-cut monuments, Ajanta cut into the basalt scarp of the Waghora ravine, Mahabalipuram carved from the granite outcrops of the coast, the monolithic rathas being the finest examples of the type. Hence (b).
• Options (a) and (c) require accepting the shared period, and (d) requires denying the rock-cut character of two of the most famous rock-cut sites in India. The trap is the assumption that two celebrated ancient sites must be contemporaneous.

• Statement 1 is incorrect and is the eliminating statement. Bitcoin is a decentralised system with no issuing or supervising authority; transactions are recorded on a distributed public ledger maintained by a peer-to-peer network and validated by proof of work, and no central bank tracks, issues or clears them. That absence of a central authority is the design premise, not an incidental feature.
• Statement 2 is correct: the system is permissionless, an address being derived from a public key that anyone may generate without registration or intermediary, and any address may transact with any other.
• Statement 3 is correct as stated: Bitcoin is pseudonymous, transactions being tied to addresses rather than to legal identities, so payment can occur without either party knowing who the other is. Hence 2 and 3, giving (b).
• Options (a) and (d) fall with statement 1, and (c) requires rejecting the open-address property, which is the most basic feature of the network. Recognising that Bitcoin was designed precisely to dispense with a trusted central intermediary settles the question at once.

• Statement 1 is incorrect. The New Development Bank was established by the BRICS grouping, Brazil, Russia, India, China and South Africa, under the agreement signed at the Fortaleza summit in July 2014, with an initial authorised capital of one hundred billion dollars and equal shareholding among the five founders. The Asia-Pacific Economic Cooperation forum is a separate consultative body on trade and investment that has established no development bank.
• Statement 2 is correct: the Bank is headquartered at Shanghai, the first regional office being opened in Johannesburg, and the founding President was an Indian, K. V. Kamath, under the rotational arrangement agreed among the members. Hence (b).
• Options (a) and (c) require accepting the APEC attribution, and (d) requires rejecting the Shanghai headquarters. The item is easy because the two facts most frequently reported about the Bank were exactly its BRICS parentage and its Shanghai seat, the latter having been the subject of comment because India secured the first presidency in exchange.

The Western Ghats Ecology Expert Panel chaired by Madhav Gadgil reported in 2011, recommending that the entire Western Ghats be treated as an ecologically sensitive area, graded into three zones with differentiated regulation, and that governance be built upward from gram sabhas. The High Level Working Group chaired by K. Kasturirangan, appointed to examine that report, submitted its own in 2013 and recommended a far smaller ecologically sensitive area of about thirty seven per cent of the Ghats, defined on the basis of natural landscape rather than administratively, with prohibitions confined to specified activities. Both therefore relate to the protection of the Western Ghats, giving (d).

• Option (a) is unconnected.
• Option (b) refers to the Ganga cleaning programmes, addressed by different institutions including the National Ganga River Basin Authority which appears at Q23 of this paper.
• Option (c) refers to interlinking of rivers, a National Water Development Agency subject. The item is easy for anyone who has followed the ecologically sensitive area controversy, which ran continuously through this period on account of State government and plantation sector opposition.

• Item 1 is not associated with Keshab Chandra Sen. The Calcutta Unitarian Committee was founded in 1821 by Rammohan Roy together with William Adam and Dwarkanath Tagore, and preceded the Brahmo Sabha of 1828. Sen was born in 1838, so he could not have been associated with its establishment, which is the cleanest way to dispose of the item.
• Item 2 is correctly associated: Sen founded the Nava Vidhan or Church of the New Dispensation in 1880, its place of worship being called the Tabernacle of New Dispensation, in which he sought to synthesise the teachings of the world's religions, a mystical turn that alienated many of his earlier followers.
• Item 3 is correctly associated: Sen established the Indian Reform Association in 1870 on his return from England, working on cheap literature, education for women, temperance and charity, and it was through this body that he pressed for what became the Native Marriage Act of 1872, fixing minimum ages for marriage and permitting inter-caste unions. Hence 2 and 3, giving (b).
• Options (a) and (d) require attributing the Unitarian Committee to him, and (c) requires rejecting the New Dispensation, which is the movement most closely identified with his later career. The item is difficult because it requires three separate attributions with no elimination route unless the candidate holds Sen's dates against Rammohan Roy's.

Both schemes were launched in November 2015 to address the same underlying problem, that gold is India's second largest import after petroleum and that very large stocks of gold sit idle in households and temples outside the financial system.

• Statement 1 is correct and is the direct object of the Gold Monetization Scheme, under which depositors surrender physical gold to banks against interest, the gold being melted and recirculated to jewellers, so the metal re-enters productive use rather than lying in a locker.
• Statement 2 is incorrect and is the eliminating statement: neither scheme has any foreign direct investment purpose, both being domestic savings and import substitution instruments, and the promotion of FDI is a wholly different policy lever.
• Statement 3 is correct and is the macroeconomic rationale for both: the Sovereign Gold Bond gives investors exposure to the gold price, plus a fixed interest coupon, without any physical metal being imported at all, so demand for gold as an asset is met by a paper claim, and gold recycled through monetization substitutes for fresh imports. The current account deficit is the ultimate target. Hence 1 and 3, giving (c).
• Options (b) and (d) fall with statement 2, and (a) requires rejecting the import objective, which is the reason the schemes exist.

The Pradhan Mantri MUDRA Yojana, launched in April 2015, provides collateral-free institutional credit up to ten lakh rupees to non-farm micro and small enterprises through banks, non-banking finance companies and microfinance institutions, refinanced by the Micro Units Development and Refinance Agency. Its loans are categorised as Shishu, Kishore and Tarun by size. The premise of the scheme is that the very large informal micro-enterprise sector was financed by moneylenders at punitive rates because it lacked collateral and documentation, so the object is to draw those borrowers into formal finance. Hence (a).

• Option (b) describes crop loans, delivered through the Kisan Credit Card and the interest subvention scheme, and is expressly excluded from MUDRA, which is non-farm; this is the strongest distractor.
• Option (c) describes old age pension, provided under the National Social Assistance Programme and the Atal Pension Yojana.
• Option (d) describes skill development funding, which runs through the National Skill Development Corporation. The discriminator is that MUDRA finances enterprises rather than persons or activities.

The Global Financial Stability Report is published twice a year by the International Monetary Fund, alongside the World Economic Outlook and the Fiscal Monitor, and assesses risks to the global financial system arising from market and credit conditions, leverage, capital flows and the health of banking and non-bank sectors. It was instituted in 2002, replacing earlier market surveillance publications, and its salience increased greatly after the global financial crisis. Hence (b).

• Option (a) is wrong: the European Central Bank publishes its own Financial Stability Review, which is regional and is the most plausible distractor by title.
• Option (c) is wrong: the IBRD is the lending arm of the World Bank Group, whose flagship publications are the World Development Report and the Global Economic Prospects.
• Option (d) is wrong: the OECD publishes the Economic Outlook and a large body of comparative policy work but not this report. The organising principle worth teaching is the division of labour among the Bretton Woods institutions: the Fund monitors macroeconomic and financial stability, the Bank finances development, so a report on the stability of the global financial system belongs to the Fund by mandate.

• Statement 1 is correct. The Atal Pension Yojana, launched in May 2015 and administered by the Pension Fund Regulatory and Development Authority, guarantees a defined monthly pension from the age of sixty, and its declared target group is workers in the unorganised sector, who fall outside the Employees' Provident Fund and the National Pension System for government employees and therefore have no institutional retirement provision.
• Statement 2 is incorrect and is the eliminating statement: there is no one-per-family restriction, and eligible members of the same household may each hold an account, which is unsurprising given that the whole object is to widen coverage rather than ration it.
• Statement 3 is correct: on the death of the subscriber the same pension amount is payable to the spouse for life, and on the death of both the accumulated corpus is returned to the nominee. Hence 1 and 3, giving (c).
• Options (b) and (d) fall with statement 2, and (a) requires rejecting the spousal continuation, which is one of the scheme's advertised features. The design principle that resolves the whole item is that a universal-coverage social security scheme does not restrict enrolment by household.

The Regional Comprehensive Economic Partnership is the free trade agreement negotiated among the ten ASEAN member states and their free trade agreement partners, originally the six countries of Australia, China, India, Japan, New Zealand and South Korea. ASEAN is not merely a participant but the institutional centre of the process: the initiative was launched at the ASEAN summit at Phnom Penh in 2012, negotiations proceeded under the guiding principles adopted by ASEAN, and the arrangement was built by consolidating the separate ASEAN plus one agreements into a single instrument. That is why the affairs of RCEP are the affairs of ASEAN, giving (b).

• Option (a) is wrong: the G20 is a macroeconomic coordination forum and negotiates no trade agreements.
• Option (c) is wrong: the Shanghai Cooperation Organisation is a Eurasian political and security grouping with no comparable trade instrument.
• Option (d) is wrong: SAARC's own trade arrangement is SAFTA, which is separate and much narrower. The elimination route is that only one of the four options is a grouping with an established practice of negotiating comprehensive trade agreements with external partners.

ITER, under construction at Cadarache in France, is a collaboration of the European Union, India, Japan, China, Russia, South Korea and the United States, building a tokamak intended to demonstrate that a burning deuterium-tritium plasma can produce ten times the power injected to heat it. Its purpose is to establish the scientific and engineering feasibility of fusion as an energy source, and India's participation, through the Institute for Plasma Research, brings both technology and eventual access to the design knowledge. If the experiment succeeds, what India gains is the capability to build fusion reactors, giving (d).

• Option (a) confuses fuel cycles: thorium belongs to fission, and India's thorium ambitions run through the three-stage programme and the Advanced Heavy Water Reactor, not through ITER.
• Option (b) is unrelated to nuclear physics of any kind.
• Option (c) commits the same category error in the opposite direction, since success in magnetic confinement fusion tells one nothing about the efficiency of fission reactors, the two processes being physically distinct. The elimination route is complete once the candidate holds fission and fusion apart, since three of the four options describe fission or non-nuclear outcomes.

• Pair 1 is correctly matched. Eripatti, literally tank land, was land whose revenue was set apart for the maintenance of the village tank, an arrangement of real importance in the Tamil country where irrigation depended on tank storage and where the assembly maintained the works from an earmarked endowment rather than from general funds.
• Pair 2 is incorrectly matched and is the decisive pair. A village or group of villages granted to Brahmanas was a brahmadeya, or an agrahara where the grant was to a body of Brahmanas. A taniyur was something different: a large village, often one that had grown out of a brahmadeya, which was detached from its kurram and constituted a separate revenue and administrative unit in its own right, the word carrying the sense of separate or autonomous.
• Pair 3 is correctly matched: ghatikas were centres of higher learning, generally attached to temples and mathas, teaching Vedic and Sanskritic subjects, Kanchipuram being the best known. Hence 1 and 3, giving (d).
• Options (a) and (c) require accepting the taniyur description, and (b) requires rejecting the eripatti endowment. The item is difficult because all three are specialist Chola administrative terms with no elimination route; the only lever is knowing that brahmadeya, not taniyur, is the word for a Brahmana grant.

• Statement 1 is correct. The International Solar Alliance was launched jointly by the Prime Minister of India and the President of France on 30 November 2015, the opening day of the twenty first Conference of Parties to the UNFCCC at Paris, with its secretariat at Gurugram, the first treaty-based international organisation headquartered in India.
• Statement 2 is incorrect. Membership was originally confined to states lying wholly or partly between the Tropics of Cancer and Capricorn, the sunshine belt where solar resource is most abundant, which by definition excluded most of Europe, Russia, Canada and the northern latitudes generally. The claim that all United Nations members belong is therefore false as of the paper, and the reasoning behind the restriction is itself the point worth knowing. Hence (a).
• Options (b) and (c) require accepting universal membership, and (d) requires rejecting the launch at COP21, which was among the most reported Indian diplomatic initiatives of the year. Universal-membership claims of this kind are almost always false and are worth treating as a standing signal in Prelims.

The European Stability Mechanism, established in 2012, is the permanent crisis resolution fund for the euro area, succeeding the temporary European Financial Stability Facility. It raises money on capital markets against callable capital subscribed by euro area members and lends to member states in financial distress, subject to conditionality negotiated with the European Commission and the IMF. Its most prominent operation was the third Greek programme agreed in 2015, which was live when this paper was set. Hence (b).

• Option (a) describes the refugee response, handled through Frontex, the European Asylum Support Office and the Commission's relocation schemes, and is the strongest distractor only because the migration crisis dominated European news in the same period.
• Option (c) describes the trade competence, which is exercised by the Commission under the Common Commercial Policy.
• Option (d) describes political dispute settlement, which runs through the Court of Justice and the Council. The word 'stability' in the name is the discriminator: in the European vocabulary of the period it denotes financial stability, as in the Stability and Growth Pact, not political or social stability.

• Statement 1 is correct. Drip irrigation delivers water through emitters directly to the root zone of the crop, so the inter-row and inter-plant surface remains dry. Weed seeds in that dry soil do not germinate, and weed pressure falls sharply compared with flood or furrow irrigation, which wets the entire field and waters the weeds along with the crop.
• Statement 2 is incorrect and is the decisive statement. Drip does not reduce soil salinity and can worsen it. Because the applied volume is small and there is no excess to percolate below the root zone, salts are not leached downward but are carried to the periphery of the wetted bulb and accumulate there as water evaporates, so a distinct salt front builds up at the margins of each emitter zone. Leaching salts out of a soil requires applying water in excess of crop demand, which is precisely what drip is designed not to do.
• Statement 3 is correct: there is no runoff and no sheet flow of water across the surface, so water-induced erosion is effectively eliminated. Hence 1 and 3, giving (c).
• Options (a) and (d) fall with the salinity claim and with the plain advantages of the method respectively, and (b) requires rejecting weed suppression.

• Statement 1 is correct. DigiLocker is a cloud-based document repository provided by the Ministry of Electronics and Information Technology as one of the flagship components of the Digital India programme, linked to the user's Aadhaar number, in which issuing authorities may place documents directly and requesting agencies may verify them.
• Statement 2 is correct and states the defining benefit of the service: because the documents sit in the cloud rather than in a physical file, they can be accessed from anywhere with a network connection, which is what makes the system useful at all. Both statements being correct, the answer is (c).
• Options (a) and (b) each reject one true proposition, and (d) rejects both. There is no trap here and no qualifier doing hidden work, so the item is easy for any candidate who has encountered the service; the wider principle is simply that documents issued into a digital repository under section 9A of the Information Technology Act and the associated rules carry the same legal standing as the original physical documents.

The Godavari and the Krishna were linked through the Pattiseema lift irrigation scheme, commissioned by Andhra Pradesh in September 2015, which lifts water from the Godavari at Pattiseema in West Godavari district into the Polavaram right main canal and thence to the Krishna at Prakasam barrage. Its significance was that it was presented as the first river link of the national interlinking programme actually to be executed, delivering Godavari surplus to the Krishna delta ahead of the completion of the Polavaram project itself. Hence (b).

• Option (a) is wrong: no Cauvery-Tungabhadra link has been executed, and the Tungabhadra is in any case a Krishna tributary.
• Option (c) is wrong: the Mahanadi-Godavari link is a proposal under the peninsular component and Sone is a Ganga tributary.
• Option (d) is wrong: the Par-Tapi-Narmada link remained a proposal and has since faced sustained opposition. The elimination route is that three options name links that exist only on the National Water Development Agency's map, and only one names a scheme that had actually delivered water.

• Statement 1 is incorrect. Space-based astronomical observatories have been flown by a considerable number of space powers besides the United States and Russia: Japan's X-ray series from Hakucho through Suzaku and Hitomi, the European Space Agency's XMM-Newton, INTEGRAL, Herschel and Planck, Italy's BeppoSAX and AGILE, China's later Insight-HXMT, and others. India was the sixth or so entrant, not the third.
• Statement 2 is incorrect on both figures. AstroSat has a lift-off mass of about 1,513 kilograms, not 2,000, and was placed in a near-equatorial low Earth orbit at roughly 650 kilometres, not 1,650. The 650 kilometre altitude and the six degree inclination were chosen deliberately to keep the spacecraft below the inner radiation belt and out of the South Atlantic Anomaly for as much of each orbit as possible, since charged particle background would otherwise swamp the X-ray detectors. Both statements being false, the answer is (d).
• Options (a), (b) and (c) each require accepting one of them. The exclusivity claim in statement 1 should trigger the same suspicion as any universal or unique claim in Prelims.

Araghatta is the Sanskrit term for the water-lifting wheel used in irrigation, the device known later as the rahat or Persian wheel, in which a chain of pots mounted on a wheel raises water from a well and discharges it into a channel. The word derives from ara, spoke, and ghatta, pot, which describes the mechanism exactly. Its diffusion, and the later addition of the pin-drum gearing that allowed animal power to be applied efficiently, materially raised the area that could be irrigated from wells and is treated in the economic history as one of the significant agrarian technologies of the period. Hence (c).

• Option (a) describes forced or bonded labour, for which the term is vishti or begar.
• Option (b) describes service assignments, for which the vocabulary is iqta, jagir or in the Deccan the various watan and inam grants.
• Option (d) describes reclamation of wasteland, again a distinct category in revenue records. The elimination route lies in the etymology: the pot element in the word points unmistakably to a water-lifting device, and a candidate who parses the Sanskrit needs no separate recall.

The Magadhas, along with the sutas and the vandins, were the bardic communities whose hereditary profession was the memorising and recitation of genealogies, dynastic accounts, panegyric and epic narrative at royal courts. Their importance to the historian is considerable: before the epics and puranas were committed to writing, the vamsanucharita sections preserving dynastic lists existed in the keeping of exactly these reciters, so the oral bardic tradition is the channel through which much early dynastic material survived. Hence (d).

• Option (a), shramana, denotes the wandering ascetic of the heterodox traditions, Buddhist, Jaina and Ajivika, defined by renunciation rather than by recitation.
• Option (b), parivrajaka, likewise denotes a wandering mendicant, the term used across traditions for one who has left household life.
• Option (c), agraharika, refers to the holder or resident of an agrahara, a village granted to Brahmanas, which is a category of landholding rather than an occupation of memorising. The elimination route is that three of the four options describe modes of life, ascetic or landed, and only one names a professional occupation.

• Statement 1 is correct: Mangalyaan is the popular name of the Mars Orbiter Mission, launched in November 2013 and inserted into Mars orbit on 24 September 2014.
• Statement 2 is incorrect and is the eliminating statement. India was not the second entity to orbit Mars after the United States. The Soviet Union achieved Mars orbit with Mars 2 and Mars 3 in 1971, and the European Space Agency's Mars Express has been in orbit since 2003, so India was the fourth.
• Statement 3 is correct: India is the only country to have succeeded in placing a spacecraft in Mars orbit at its first attempt. The Soviet Union, the United States, Japan and the European Space Agency all suffered failures before or during their early Mars campaigns, and the historic failure rate of Mars missions is roughly one in two, which is what makes the achievement notable. Hence 1 and 3, giving (c).
• Options (a), (b) and (d) each mishandle statement 2. The elimination route is available to anyone who recalls the Soviet Mars programme, and the internal tension in the question is itself a clue: statements 2 and 3 make different exclusivity claims about the same mission, and only one can carry the distinction.

The split at Surat in December 1907 arose from the accumulated divergence between the moderates and the extremists over method. The extremists, led by Tilak, Lajpat Rai and Bipin Chandra Pal, had concluded that constitutional agitation, petition and prayer would extract nothing from the British, and pressed for the extension of swadeshi, boycott and national education from Bengal to the whole country; the moderates wished to confine the programme to Bengal and to keep faith with negotiation, encouraged by the prospect of the reforms that became the Morley-Minto scheme. The immediate flashpoints were the presidency and the disputed resolutions, but the underlying cause is the extremists' loss of confidence in the moderate method, giving (b).

• Option (a) is wrong on both attribution and effect: communal representation came through the Morley-Minto reforms of 1909, after the split, and did not cause it.
• Option (c) is wrong: the Muslim League was founded in 1906 and is unconnected with an internal Congress division.
• Option (d) inverts the facts of the presidency dispute, which concerned Rash Behari Ghosh and Lala Lajpat Rai rather than Aurobindo Ghosh. Chronology alone disposes of options (a) and (c).

The Cripps Mission of March 1942 offered, after the conclusion of the war, the establishment of an Indian Union with Dominion status, associated with the United Kingdom and the other Dominions by a common allegiance to the Crown but equal to them in every respect and in no way subordinate in domestic or external affairs. A constitution-making body would be set up, provinces unwilling to accede would be entitled to retain their existing constitutional position and to negotiate a separate Union, and the British would retain responsibility for defence during the war. Hence (d).

• Option (a) is wrong because Dominion status is not complete independence; that gap is exactly what Gandhi's reported description of the offer as a post-dated cheque was about, and the Congress rejection followed.
• Option (b) is wrong: the plan did not partition India, though the non-accession clause conceded the principle of separation and was criticised on that ground.
• Option (c) is wrong: no republic was contemplated, Dominion status presupposing allegiance to the Crown; India's decision to remain in the Commonwealth as a republic came only with the London Declaration of 1949. The discriminator throughout is the distinction between Dominion status and independence.

• Pair 1 is incorrect: Bodhgaya lies in Bihar, in the historic region of Magadha, whereas Baghelkhand is the plateau region of eastern Madhya Pradesh around Rewa and Satna.
• Pair 2 is correct: Khajuraho lies in Chhatarpur district of Madhya Pradesh, squarely within Bundelkhand, the region straddling Madhya Pradesh and Uttar Pradesh that takes its name from the Bundela Rajputs.
• Pair 3 is incorrect: Shirdi is in Ahmednagar district in western Maharashtra, whereas Vidarbha is the eastern region of the State around Nagpur and Amravati.
• Pair 4 is incorrect: Nashik lies in northern Maharashtra, in the tract conventionally called Khandesh or North Maharashtra, whereas Malwa is the plateau of western Madhya Pradesh around Indore and Ujjain.
• Pair 5 is correct: Tirupati is in Chittoor district of Andhra Pradesh, within Rayalaseema, the southern interior region of the State. Hence 2 and 5, giving (c). The elimination route is efficient: recognising either that Bodhgaya is in Bihar or that Shirdi is not in Vidarbha removes three of the four options, since only (c) excludes both. The item tests regional rather than administrative geography, which is what makes it harder than it looks.

Article 249 provides that if the Council of States declares by resolution supported by not less than two-thirds of the members present and voting that it is necessary or expedient in the national interest that Parliament should make laws with respect to a matter in the State List specified in the resolution, Parliament may do so while the resolution remains in force, which is one year at a time, extendable, with the law ceasing to have effect six months after the resolution expires. Hence (d).

• Options (a) and (b) are wrong because the power is vested in the Rajya Sabha, not the Lok Sabha, and the reason is structural: the Rajya Sabha represents the States in the federal scheme, so it is the House whose consent legitimises a Union incursion into the State field.
• Option (c) is wrong on the majority, requiring only a simple majority of total membership rather than two-thirds of those present and voting. The two limbs to hold precisely are the House, which follows from the federal logic, and the formula, two-thirds of members present and voting rather than of total membership, this being a special majority of the kind used in Articles 249 and 312 and distinct from the amending majority under Article 368.

Rajasthan explored the feasibility of an artificial inland port, the concept being to connect a landlocked location to the Arabian Sea by a long navigational channel cut across the low-lying saline tract of the Rann of Kachchh, the attraction being direct maritime access for a State whose trade otherwise moves overland to the Gujarat ports. Hence (d). The distractor structure is worth noting.

• Options (a) and (c), Andhra Pradesh and Karnataka, are coastal States and therefore have no need whatever of an artificial inland port connected by a channel, which should exclude them on the logic of the question rather than on recall.
• Option (b), Chhattisgarh, is genuinely landlocked and is the only serious competitor, but it lies far inland across the Deccan interior with no plausible channel alignment, whereas Rajasthan abuts the Rann and the Gulf of Kachchh, which is what made the proposal conceivable at all. The item is difficult because the proposal was reported only briefly and never advanced, but the partial elimination route through coastal geography raises it above pure recall.

• Statement 1 is incorrect on both limbs. The Agreement was not signed by all United Nations members, participation being voluntary and several states remaining outside; and its entry into force was not fixed for 2017 but was conditioned on ratification by at least fifty five parties accounting for at least fifty five per cent of global emissions, a threshold crossed unexpectedly early so that it entered into force on 4 November 2016, months after this paper was set.
• Statement 2 is correct and reproduces Article 2: holding the increase in global average temperature to well below two degrees above pre-industrial levels and pursuing efforts to limit it to one and a half degrees.
• Statement 3 is incorrect on the figure, which is the decisive error: the commitment carried forward from Copenhagen and reaffirmed at Paris was one hundred billion dollars a year by 2020, not one thousand billion, an overstatement by a factor of ten. Hence (b).
• Options (a), (c) and (d) each accept a false statement.
• Statement 3 should fail on plausibility alone even for a candidate who has forgotten the number, one thousand billion dollars a year being of the order of the entire global development finance flow.

• Statement 1 is incorrect. The Sustainable Development Goals were adopted by the United Nations General Assembly in September 2015 as part of the 2030 Agenda, emerging from the Rio plus 20 conference of 2012 and the Open Working Group process that followed, and succeeding the Millennium Development Goals. The Club of Rome did publish The Limits to Growth in 1972, an influential systems-dynamics study of the consequences of exponential growth against finite resources, but that report proposed no goals and has no institutional connection with the SDGs; the date is offered precisely because it coincides with the Stockholm Conference of the same year and looks plausible.
• Statement 2 is correct: the seventeen goals and one hundred and sixty nine targets are to be achieved by 2030, which is why the framework is called the 2030 Agenda. Hence (b).
• Options (a) and (c) require accepting the Club of Rome attribution, and (d) requires rejecting the target year, which is contained in the name of the Agenda itself. The organising principle is that the SDGs are an intergovernmental instrument adopted by states, so no private think tank could have proposed them in any operative sense.

The Man Who Knew Infinity takes its title from Robert Kanigel's 1991 biography of Srinivasa Ramanujan, and follows Ramanujan from his clerkship at the Madras Port Trust through his correspondence with G. H. Hardy and his years at Trinity College, Cambridge. Hence (a).

• Option (b), Subrahmanyan Chandrasekhar, was the astrophysicist who established the limiting mass of a white dwarf and shared the Nobel Prize in 1983; his conflict with Eddington is a well-known episode but not the subject of this film.
• Option (c), Satyendra Nath Bose, gave the statistics that bears his name and, with Einstein, the Bose-Einstein condensate.
• Option (d), C. V. Raman, won the Nobel Prize in 1930 for the scattering effect named after him. The title itself supplies a strong route without any knowledge of the film: infinity is a mathematician's preoccupation rather than a physicist's, and the three distractors are all physicists while only Ramanujan is a mathematician, which resolves the item on a single distinction.

• Statement 1 is incorrect. Article 243F provides that a person shall be qualified to be chosen as a member of a Panchayat if he has attained the age of twenty one years, notwithstanding that he may be under twenty five, and is otherwise qualified for election to the State Legislature. The twenty five year threshold applies to the Lok Sabha and to State Legislative Assemblies, and the framers of the Seventy Third Amendment deliberately lowered it for local bodies to widen participation.
• Statement 2 is correct. Article 243E provides that a Panchayat continues for five years from the date appointed for its first meeting and no longer, and that a Panchayat constituted upon the dissolution of a Panchayat before the expiry of its duration continues only for the remainder of the period for which the dissolved Panchayat would have continued had it not been dissolved. The purpose is to remove any incentive for a State Government to dissolve a Panchayat in order to reset the electoral clock in its favour. A further safeguard is that no dissolution occurs where the unexpired period is less than six months. Hence (b).
• Options (a) and (c) fall on the age, and (d) on the remainder-period rule.
