2015

• Option (c) is correct. PMJDY was launched on 28 August 2014 as the National Mission for Financial Inclusion, its stated object being universal access to banking through a basic savings bank deposit account with a RuPay debit card, accident and life cover, and an overdraft facility after satisfactory operation.
• Option (a) is wrong because subsidised housing credit is the province of the housing schemes, later consolidated as Pradhan Mantri Awas Yojana, and PMJDY carries no housing component.
• Option (b) is wrong because Self-Help Group promotion runs through the rural livelihoods architecture, SGSY and its successor NRLM, not through a banking access mission.
• Option (d) is the closest distractor and fails on a single word: PMJDY is universal in design, opening accounts for every unbanked household irrespective of category, whereas (d) narrows it to marginalized communities. The governing distinction is between a targeted transfer scheme and a universal access mission. Elimination route: the mission statement and the scheme name itself, jan dhan, both point at bringing people into the formal financial system.

• Statement 1 is correct. The Fourteenth Finance Commission under Y. V. Reddy raised the States' share in the net proceeds of Union tax revenues from 32 percent to 42 percent for 2015-20, the largest single increase any Finance Commission has recommended.
• Statement 2 is incorrect. The Fourteenth Finance Commission departed deliberately from its predecessors by declining to make sector-specific grants; it confined its grants to local bodies, disaster relief and post-devolution revenue deficit grants, reasoning that a larger untied devolution should replace conditional sectoral transfers and that sectoral prioritisation was for the States to make. The official answer (a) follows.
• Options (c) and (d) are excluded by statement 1, which was extensively reported. The item is decided entirely by statement 2, and a candidate who knew only the 42 percent figure would still have to choose between (a) and (c). The governing principle is that the Fourteenth Finance Commission's defining choice was untied devolution over conditional grants.

• Option (b) is correct. The Fortaleza Declaration issued at the Sixth BRICS Summit in Fortaleza, Brazil in July 2014 recorded the decision to establish the New Development Bank with authorised capital of 100 billion dollars and the Contingent Reserve Arrangement of the same size.
• Option (a) is wrong: ASEAN outcome documents are named for its own venues, such as the Bali Concord.
• Option (c) is wrong: OECD ministerial outcomes are not issued in this form.
• Option (d) is wrong: WTO ministerial outcomes take the names Doha, Bali and Nairobi. Elimination route: Fortaleza is a Brazilian city, and of the four groupings listed only BRICS has Brazil as a member, which settles the item without any recall of the declaration's content.

The tax to GDP ratio measures tax revenue as a proportion of national output.

• Statement 1 is treated as correct. In a slowdown, corporate profits, transaction volumes and consumption contract faster than nominal GDP, so direct and indirect collections fall disproportionately and the ratio declines; a falling ratio is therefore consistent with, and taken as an indication of, decelerating growth.
• Statement 2 is incorrect. The ratio carries no information about how income is distributed. If anything the causation runs the other way, since income concentrated at the top sits in the taxable bracket and, with a progressive structure, tends to raise rather than lower the ratio; a low ratio is as consistent with a large untaxed informal sector or with generous exemptions as with any distributional pattern. The official answer (a) follows.
• Options (b), (c) and (d) all fail on statement 2 or on statement 1 respectively. Note that the link asserted in statement 1 is indirect and admits of exceptions, such as a ratio falling because of a deliberate rate cut or a widening of exemptions in a growing economy; the item is answerable because statement 2 is clearly weaker, not because statement 1 is tight.

Tropical cyclogenesis requires sea surface temperatures of about 26.5 degrees Celsius through a deep mixed layer, a pre-existing low level disturbance to organise convection, weak vertical wind shear, sufficient Coriolis force and a moist middle troposphere. In the South Atlantic and the south-eastern Pacific the seed disturbance is missing, because the Inter-Tropical Convergence Zone in these longitudes remains north of the equator through almost the whole year and rarely migrates into the southern tropics, so option (b) is the answer.

• Option (c) is wrong on the stem's own terms: the stem specifies tropical latitudes, where Coriolis force is adequate; it is only within about five degrees of the equator that Coriolis vanishes.
• Option (d) is wrong because tropical cyclones form over open ocean and land is not a requirement but a destroyer of them.
• Option (a) is the strongest distractor and is not wholly false, since the Benguela and Humboldt upwelling systems do keep coastal waters cool in exactly these two regions, but low sea surface temperature is a contributory condition confined to the eastern margins rather than the reason covering the whole region, and strong vertical shear operates alongside it.

• Option (d) is correct. The easternmost point of India lies in Arunachal Pradesh near Kibithu in Anjaw district at about 97 degrees 25 minutes East, and the westernmost point lies in Gujarat at Guhar Moti in the Kachchh region at about 68 degrees 7 minutes East.
• Options (a) and (c) fail because Assam lies well west of Arunachal Pradesh.
• Options (a) and (b) fail because Rajasthan, though it has the longest stretch of the western international border and is the largest State by area, does not reach as far west as the Kachchh peninsula. The trap is the association of Rajasthan with India's western extremity, which is true of the border but not of longitude.

• Statement 1 is correct. The Directive Principles in Part IV set out the social and economic goals of the State, and both Ambedkar and later commentators describe them as establishing economic and social democracy to complete the political democracy secured by Part III.
• Statement 2 is correct and is textual: Article 37 provides that the provisions of Part IV shall not be enforceable by any court, while declaring them nevertheless fundamental in the governance of the country and imposing a duty on the State to apply them in making laws. The official answer (c) follows.
• Options (a), (b) and (d) each require one of the two statements to be false, and neither is. The distinction the question rests on, and which the same paper tests elsewhere, is that non-enforceability by a court is not the same as absence of constitutional obligation.

• Option (b) is correct on the position obtaining when the paper was set. The Index of Eight Core Industries covers coal, crude oil, natural gas, refinery products, fertilizers, steel, cement and electricity, and at the 2004-05 base these eight carried a combined weight of 37.90 percent in the Index of Industrial Production. Within that, electricity carried the largest weight at 10.32, followed by steel at 6.68, refinery products at 5.94, crude oil at 5.22, coal at 4.38, cement at 2.41, natural gas at 1.71 and fertilizers at 1.25.
• Option (d) is the runner up and the intended trap, steel being second.
• Options (a) and (c) are well down the order, fertilizers carrying the smallest weight of all eight. The elimination route is that electricity is the universal intermediate input, consumed by every other core industry, so its share of industrial value is necessarily the largest.

• Option (b) is correct. Keibul Lamjao in Manipur, on the southern part of Loktak Lake, is the only floating national park in the world, its surface formed of phumdis, mats of decomposing vegetation, soil and organic matter, and it is the last natural habitat of the sangai or brow antlered deer.
• Option (a) is wrong: Bhitarkanika in Odisha is a mangrove ecosystem in the Brahmani Baitarani delta, known for the saltwater crocodile.
• Option (c) is wrong: Keoladeo Ghana at Bharatpur is a man made shallow freshwater wetland famous for migratory waterfowl, but its vegetation is rooted, not floating.
• Option (d) is wrong: Sultanpur in Haryana is a small shallow lake bird sanctuary raised to national park status. The single word that decides the item is floating, which is unique to the phumdi ecosystem.

• Statement 1 is correct. The National Innovation Foundation, set up at Ahmedabad in 2000, is an autonomous body of the Department of Science and Technology.
• Statement 2 is incorrect and inverts the Foundation's purpose. NIF exists to scout, document, value add and protect grassroots technological innovation and outstanding traditional knowledge developed by people in the unaided or informal sector, typically farmers, artisans and school children; it is a grassroots innovation body, not a frontier research body, and its work is not built on collaboration with foreign scientific institutions. The official answer (a) follows.
• Options (b) and (d) are excluded by statement 1 and option (c) by statement 2. The elimination route is the mismatch between the word innovation, which in Indian science administration attaches to grassroots and translational work, and the language of advanced research in premier institutions, which describes bodies such as SERB or the international bilateral programmes.

• Statement 1 is incorrect, and the biology runs the opposite way. Biological nitrogen fixation is energetically expensive, so both free living diazotrophs and rhizobial symbionts down regulate nitrogenase synthesis when mineral nitrogen is abundant; heavy urea application suppresses nodulation and fixation rather than promoting proliferation.
• Statement 2 is correct. Ammoniacal and urea fertilizers acidify soil through nitrification, in which ammonium is oxidised to nitrate with the release of hydrogen ions, and repeated application measurably lowers soil pH.
• Statement 3 is correct. The nitrate ion is an anion and is repelled rather than retained by the predominantly negatively charged soil colloids, so it moves freely with percolating water into groundwater, which is the origin of nitrate contamination and of the drinking water standard set for it. The official answer (c) follows. Elimination route: recognising the feedback inhibition in statement 1 removes options (a) and (d) at once, and statement 3 is standard, which removes (b).

• Statement 1 is incorrect. Its second half is true, CITES being an intergovernmental agreement, but its first half is false: IUCN is not an organ of the United Nations. It is a membership union of sovereign States, government agencies and non-governmental organisations, founded in 1948 at Fontainebleau, which holds observer status at the United Nations General Assembly, and observer status is precisely what distinguishes it from an organ. A compound statement fails if either half fails.
• Statement 2 is correct; IUCN supports and runs field projects worldwide alongside its better known Red List and Commission work.
• Statement 3 is correct and is CITES's own formulation: the Convention binds Parties in international law but is not self executing, and each Party must adopt domestic legislation to give it effect, which is why the Convention is implemented in India through the Wild Life (Protection) Act and the customs regime. The official answer (b) follows. Elimination route: rejecting the organ of the United Nations claim removes options (a), (c) and (d) in one step, which makes this an easier item than its three statement form suggests.

• Option (a) is correct. The Fair and Remunerative Price is notified under the Sugarcane (Control) Order 1966 and is approved by the Cabinet Committee on Economic Affairs each sugar season.
• Option (b) is the intended trap and turns on the difference between recommending and approving: the Commission for Agricultural Costs and Prices works out and recommends the price, as it does for minimum support prices, but the decision is the Cabinet's.
• Option (c) is wrong: the Directorate of Marketing and Inspection administers agricultural grading and the AGMARK standards.
• Option (d) is wrong: an Agricultural Produce Market Committee regulates transactions in a notified market yard and has no price fixing power of this kind. The governing principle is that every administered price in Indian agriculture is recommended by a technical body and approved by the executive.

The equatorial counter-current flows eastward in a narrow band between the westward flowing North and South Equatorial Currents. The key takes option (b). The mechanism is that the trade driven equatorial currents converge water and drive it west, piling it against the western margin of the ocean basin and raising sea level there by tens of centimetres; the resulting east-west pressure gradient forces a return flow, which surfaces as the counter-current in the zone between the two westward drifts.

• Option (a) is wrong because the Earth's rotation deflects moving water rather than driving it eastward, and it deflects in opposite senses in the two hemispheres.
• Option (c) is wrong because salinity contrasts drive the deep thermohaline circulation on a timescale of centuries, not a surface current of this speed.
• Option (d) is the serious competitor: the doldrums belt of calms is where the counter-current is found, because there the weak trades cannot oppose the return flow, but calm is the permissive condition that allows the current to surface rather than the force that generates it.

• Pair 1 is correct. Srisailam, seat of the Mallikarjuna jyotirlinga, stands on the Krishna within the Nallamala Hills of the Eastern Ghats in Andhra Pradesh.
• Pair 2 is incorrect. Omkareshwar, also a jyotirlinga, is on Mandhata island in the Narmada in Madhya Pradesh, in the trough between the Vindhya and Satpura ranges, whereas the Satmala Hills are part of the Sahyadri offshoots in the Nashik region of Maharashtra.
• Pair 3 is incorrect. Pushkar, with its Brahma temple, lies in the Aravalli near Ajmer in Rajasthan, while the Mahadeo Hills are a section of the Satpura in Madhya Pradesh containing Pachmarhi and Dhupgarh. The official answer (a) follows. Elimination route is clean and single step: Pushkar's location in the Aravalli is common knowledge, and rejecting pair 3 eliminates options (b), (c) and (d) together, leaving (a) without any need to place the Satmala Hills.

• Statement 1 is correct. The Anarchical and Revolutionary Crimes Act of 1919, universally called the Rowlatt Act, gave effect to the report of the Sedition Committee chaired by Justice Sidney Rowlatt, which recommended detention without trial and trial without jury for political offences.
• Statement 2 is correct. Gandhi built the satyagraha through the Satyagraha Sabha founded in February 1919 and drew on existing organisational networks, principally the Home Rule Leagues along with pan-Islamist and Punjab based groupings, this being his first attempt at a nationwide agitation before the Congress machinery was his to command.
• Statement 3 is incorrect and is settled by chronology alone: the Simon Commission landed at Bombay in February 1928 to the greeting of black flags, nine years after the Rowlatt Satyagraha of 1919. The official answer (b) follows. Elimination route: the date of the Simon Commission removes options (c) and (d) at once, and statement 1 is standard, which removes (a).

• Option (b) is correct. The West African Ebola epidemic of 2014 to 2016, the largest on record, was centred on Guinea, where the index case was traced to Meliandou in December 2013, and on the neighbouring states of Liberia and Sierra Leone; the World Health Organization declared it a Public Health Emergency of International Concern in August 2014.
• Option (a) is wrong: Syria and Jordan were in the news for the civil war and the refugee inflow.
• Option (c) is wrong: the Philippines had earlier reported Reston ebolavirus in macaques, which does not cause human disease, but no human outbreak.
• Option (d) is wrong: the Caribbean states listed had no Ebola cases, and the 2014 outbreak in that region was chikungunya. Elimination route: Ebola virus disease is a zoonosis of Central and West African forest ecosystems with fruit bats as the reservoir, so only the African option can be right.

• Statement 1 is correct. Fly ash bricks and blocks are an established construction material, and the Fly Ash Notification of 1999 under the Environment (Protection) Act made their use mandatory within a specified radius of coal based thermal power stations.
• Statement 2 is correct. Fly ash is a pozzolana: its amorphous silica reacts with the calcium hydroxide liberated during cement hydration to form additional binding compounds, which is why it substitutes for a proportion of Portland cement in Portland Pozzolana Cement and in ready mixed concrete, improving workability and long term strength while cutting clinker demand.
• Statement 3 is incorrect. Fly ash contains silica, alumina, iron oxide and calcium oxide as major constituents, and also carries trace toxic elements including arsenic, lead, mercury, chromium, cadmium and selenium, which is exactly why unlined ash ponds are a groundwater and health hazard. The official answer (a) follows. Elimination route: the absolutism of statement 3, which uses both only and does not contain any, is the standard signal of a false statement, and rejecting it removes options (c) and (d), while statement 1 is uncontroversial and removes (b).

• Statement 1 is correct. The dugong is the only strictly herbivorous marine mammal, an obligate seagrass grazer of the order Sirenia, which is why its distribution maps exactly onto seagrass meadows.
• Statement 2 is incorrect. In Indian waters the dugong survives only in the Gulf of Mannar and Palk Bay, the Gulf of Kachchh and the Andaman and Nicobar Islands, all seagrass habitats; it is absent from most of the mainland coast.
• Statement 3 is correct: the dugong is listed in Schedule I of the Wild Life (Protection) Act 1972 and is also in CITES Appendix I. The official answer (c) follows. Elimination route: statement 2 is the discriminator, and the dependency of the animal on seagrass beds, established by statement 1, itself shows that it cannot occur along the entire coast, so the two statements are internally linked and a candidate who understands the first can reason to the second.

• Option (d) is correct. Global Economic Prospects is a World Bank flagship publication, issued twice a year in January and June, carrying growth forecasts for the world economy and for developing regions.
• Option (a) is wrong: the Asian Development Bank publishes the Asian Development Outlook.
• Option (b) is wrong: the European Bank for Reconstruction and Development publishes the Transition Report.
• Option (c) is wrong: the Federal Reserve publishes the Beige Book and the Monetary Policy Report and does not forecast the global economy in this form. The near neighbour the candidate must not confuse this with is the International Monetary Fund's World Economic Outlook, which is not among the options. The governing distinction within the Bretton Woods pair is that the Fund watches macroeconomic stability while the Bank watches development and growth prospects.

The Statutory Liquidity Ratio is the minimum proportion of net demand and time liabilities that a bank must maintain in cash, gold and approved securities, mainly government securities. Cutting it by 50 basis points releases funds previously locked in those holdings, enlarges the pool of lendable resources, and by increasing the supply of credit tends to soften lending rates, so option (c) is correct.

• Option (d) is the exact inverse of the effect and can be discarded at once.
• Option (a) fails on the word drastically; a marginal statutory relaxation works through the credit channel with a lag and does not move the growth rate sharply, and transmission depends on demand for credit.
• Option (b) fails because foreign institutional flows respond to relative returns, exchange rate expectations and macroeconomic stability rather than to a domestic reserve requirement. The governing principle is that SLR and CRR are quantitative instruments acting on the volume of lendable resources, and relaxing either is expansionary.

• Statement 1 is correct. Nanoscale carriers such as liposomes, polymeric micelles, dendrimers and gold nanoparticles carry a drug payload to a chosen site, by passive accumulation through the enhanced permeability and retention effect of leaky tumour vasculature and by active targeting through ligands that bind receptors overexpressed on the target cell. Doxorubicin in liposomal form was already in clinical use well before this paper.
• Statement 2 is correct. Non-viral nanoparticle vectors, principally lipid and polymeric nanoparticles, are a principal route for delivering nucleic acids into cells, the delivery problem rather than the editing chemistry being the main obstacle in gene therapy. The official answer (c) follows, and there is no elimination route, both statements having to be judged independently.

• Option (b) is correct. Agriculture and markets and fairs are State subjects under Entries 14 and 28 of the State List, so regulation of agricultural produce markets is by State legislation, the Agricultural Produce Market Committee Acts, under which notified market areas and market yards are constituted and transactions in them regulated.
• Option (a) is wrong: the Essential Commodities Act empowers the government to control production, supply, distribution and stock limits of essential commodities in order to check hoarding, which is a control over trade in a commodity rather than regulation of the market institution.
• Option (c) is wrong: the 1937 Act provides for the grading and marking of agricultural produce and is the statutory basis of AGMARK.
• Option (d) is wrong: those orders deal with food processing and safety standards. The governing principle is the constitutional division of powers, which places the market itself with the States.

• Option (c) is correct. The Gangetic river dolphin, Platanista gangetica, was declared the National Aquatic Animal in October 2009 at the first meeting of the National Ganga River Basin Authority. It is a functionally blind freshwater cetacean that navigates and hunts by echolocation, and is an indicator species for the health of the Ganga system.
• Options (a), (b) and (d) are all Schedule I species of conservation concern and all are aquatic or semi-aquatic, but none carries national symbol status. The elimination route is the association of the national symbol with the Ganga, which was the object of the flagship river programme under which the designation was made.

The official answer is (d), none of the three. The Congress Socialist Party was founded at Patna in 1934 by Jayaprakash Narayan, Acharya Narendra Deva, Minoo Masani, Achyut Patwardhan and others as a socialist bloc within the Congress.

• Statement 1 is incorrect: boycott of foreign goods and refusal to pay taxes were the instruments of the Gandhian mass movements and of the Swadeshi programme before them, not of the Congress Socialist Party, whose programme was the transfer of power to the producing masses, nationalisation of key industries, abolition of landlordism without compensation, and the organisation of workers and peasants.
• Statement 2 is incorrect and is the sharpest of the three: the Congress Socialists were democratic socialists who explicitly rejected the dictatorship of the proletariat, and that rejection was the principal line of division between them and the Communist Party of India, with which they had an uneasy relationship through the 1930s.
• Statement 3 is incorrect: the party opposed separate electorates and communal representation altogether, holding that class organisation across religious lines was the answer to communalism.
• Options (a), (b) and (c) each require at least one statement to be true. There is no elimination route, and an all correct or none option set of this kind is unusually punishing, since a candidate must be confident about all three propositions before marking None.

• Statement 1 is correct. Under Article 109 a Money Bill goes to the Rajya Sabha only as a transmitted Bill; the Council may make recommendations within fourteen days, but the Lok Sabha may accept or reject them, and if the Bill is not returned within fourteen days it is deemed passed. The Council therefore cannot reject or amend.
• Statement 2 is correct: Article 113(2) confines the power to assent to or refuse assent to any demand, or to reduce it, to the House of the People.
• Statement 3 is incorrect. Article 112 requires the Annual Financial Statement to be laid before both Houses, and Article 113(1) expressly preserves the right of either House to discuss the estimates; what the Rajya Sabha lacks is the power to vote on the demands, not the right to debate the Budget, and in practice it holds a full general discussion every year. The official answer (b) follows. The governing principle is that the financial subordination of the Rajya Sabha is a subordination in voting power, not in deliberative power, and statement 3 is the standard trap built on conflating the two. Elimination route: rejecting statement 3 removes options (c) and (d), and statement 1 is textbook, which removes (a).

• Option (b) is correct. The Montagu-Chelmsford reforms enacted as the Government of India Act 1919 for the first time separated central and provincial subjects and provincial sources of revenue, relaxing the total central control that the 1861 and 1919 predecessors had maintained, and then subdivided the provincial list into reserved subjects administered by the Governor with his executive council and transferred subjects administered by ministers responsible to the legislature, the arrangement known as dyarchy. That demarcation of jurisdiction is the Act's defining structural contribution and the seed of the federal division completed in 1935.
• Option (a) is wrong: separation of the judiciary from the executive was a Directive Principle of the Constitution of India, and no colonial statute of this period effected it.
• Option (c) is wrong: the powers of the Secretary of State and the Viceroy were not the subject of clear definition in the Act, although the Act did provide for a High Commissioner and shifted part of the Secretary of State's expenditure to the British exchequer.
• Option (d) fails once (b) is established. The elimination route is that the terms central and provincial subjects belong to 1919 in the way that provincial autonomy and federation belong to 1935.

• Option (c) is correct. The Consumer Price Index for Industrial Workers is compiled and released monthly by the Labour Bureau, an attached office of the Ministry of Labour and Employment, at Shimla and Chandigarh, from retail price data collected in selected industrial centres. It is the series used to fix dearness allowance for central government employees and to revise minimum wages, which is why it sits with the labour ministry rather than with a statistical or monetary body.
• Option (a) is wrong: the Reserve Bank uses CPI as the target for flexible inflation targeting but does not compile any price index.
• Option (b) is wrong: the Department of Economic Affairs prepares the Budget and the Economic Survey.
• Option (d) is wrong: the Department of Personnel and Training administers services matters and has no statistical function. The governing distinction the candidate needs is between the compiling agency and the using agency, and the second distinction is that the combined CPI for Rural, Urban and Combined is put out by the National Statistical Office, whereas the occupation specific series for industrial workers, agricultural labourers and rural labourers belong to the Labour Bureau.

• Statement 1 is correct. The IceCube Neutrino Observatory at the Amundsen-Scott South Pole Station instruments a cubic kilometre of Antarctic ice with 5160 digital optical modules on 86 strings, making it the largest neutrino detector built. It works by detecting the Cherenkov light emitted when a neutrino interaction produces a relativistic charged secondary in the ice, the ice serving as both target mass and detecting medium.
• Statement 3 is correct: the strings hang between about 1450 and 2450 metres below the surface, deep enough for the ice to be bubble free and optically clear, with the IceTop array at the surface.
• Statement 2 is treated as correct by the key. IceCube's primary mission is high energy astrophysical neutrino astronomy, but indirect dark matter search is a published part of its programme, since neutralino or WIMP annihilation in the Sun, the Earth's core or the galactic centre would produce a neutrino excess from those directions, and IceCube has set some of the strongest limits on spin dependent WIMP-proton cross sections. The official answer (d) follows. Elimination route: statements 1 and 3 are secure, which removes (a) and (b) at once, so the item reduces to a judgement on statement 2.

• Option (c) is correct. All three terms belong to the World Trade Organization. The Agreement on Agriculture, one of the Uruguay Round agreements in force from 1995, disciplines market access, domestic support and export subsidies, and classifies domestic support into the Amber, Blue and Green Boxes. The Agreement on the Application of Sanitary and Phytosanitary Measures governs food safety and animal and plant health measures, requiring them to be scientifically justified and not disguised protection. The Peace Clause is the interim understanding reached at the Bali Ministerial in December 2013 and made open ended in November 2014, under which members agreed not to bring dispute proceedings against a developing country whose public stockholding for food security purposes breaches its Amber Box ceiling, an outcome India pressed for to protect minimum support price procurement.
• Option (a) is wrong: the Food and Agriculture Organization sets standards through Codex jointly with the World Health Organization but concludes no such trade agreements.
• Options (b) and (d) are environmental bodies with no agriculture trade instruments. Elimination route: the phrase Peace Clause has no meaning outside trade law, which settles the item by itself.

• Statement 1 is correct. Near Field Communication is a short range contactless technology operating at 13.56 megahertz, in which an initiator generates an alternating magnetic field and the target either powers itself from that field, in passive mode, or generates its own, in active mode. The coupling is inductive and takes place in the near field of the antenna, which is what the name records.
• Statement 2 is incorrect and is the whole point of the item: the working range of NFC is about four centimetres, deliberately so, because proximity is itself the security model. A metre would be the range of Bluetooth Low Energy or of a passive ultra high frequency RFID tag, not of NFC.
• Statement 3 is correct: NFC defines only the link, and application layers built on it, such as EMV contactless payment or secure element based ticketing, routinely apply encryption and cryptographic authentication to the payload. The official answer (c) follows. Elimination route: knowing the four centimetre range removes options (a) and (d) at once, and statement 1 is secure, which removes (b). The governing principle is that near field means the reactive region within a fraction of a wavelength of the antenna, which for 13.56 megahertz is centimetres, not metres.

• Option (b) is correct. The Golan Heights is a basalt plateau in the Levant, captured by Israel from Syria in the Six Day War of 1967 and effectively annexed by Israeli law in 1981, an act not recognised internationally. It lies at the junction of Israel, Syria, Lebanon and Jordan, commands the Sea of Galilee and its headwaters, and is patrolled by the United Nations Disengagement Observer Force, whose position became precarious during the Syrian civil war when armed groups overran parts of the area of separation and detained peacekeepers in 2013 and 2014.
• Options (a), (c) and (d) name regions in which no such place exists. The elimination route is that the name recurs in reporting on Israel and Syria, and even a candidate who cannot place the plateau will associate it with that conflict.

• Option (c) is correct. Convertibility is the freedom to exchange domestic currency for foreign currency and back at market determined rates without administrative permission. India adopted full current account convertibility in August 1994 on accepting the obligations of Article VIII of the Articles of Agreement of the International Monetary Fund, while capital account convertibility remains partial and calibrated, the Tarapore Committees of 1997 and 2006 having laid down preconditions and a roadmap.
• Option (a) describes the gold standard and the gold convertibility of the dollar under Bretton Woods, abandoned in 1971, and is a historical concept rather than the meaning of the term.
• Option (b) is the definition of a floating exchange rate, which is a related but distinct idea: a currency can be convertible while its rate is managed, and a rate can float within a regime that still restricts capital account transactions.
• Option (d) confuses convertibility with the development of an onshore foreign exchange market. The governing distinction is between the freedom to transact, which is convertibility, and the mechanism of price determination, which is the exchange rate regime.

• Pair 1 is incorrect. Champaka is the old name of Chamba in the western Himalaya, in present day Himachal Pradesh, founded in the tenth century by Raja Sahil Varman and named for his daughter Champavati; it is not in Central India.
• Pair 2 is correct. Durgara is the early name of the Dogra country around Jammu, the term Dogra deriving from it, and it appears in inscriptions and in Kalhana's Rajatarangini as a hill state on the Chenab.
• Pair 3 is incorrect. Kuluta is the Kullu valley, again in Himachal Pradesh, a name known from the Allahabad pillar inscription of Samudragupta and from Varahamihira; Malabar is the Kerala coast. The official answer (b) follows. Elimination route: recognising either Champaka as Chamba or Kuluta as Kullu removes three options and leaves only (b), and the two names are close enough to their modern forms for a candidate with a feel for Sanskritic place names to make the connection. Without that, the item is unanswerable from standard preparation, which is what places it at the difficult end.

• Option (a) is correct. Article 108 permits the President to summon a joint sitting to resolve a deadlock over an ordinary Bill, and Article 108(4) provides that the Bill shall be deemed passed if it is agreed to at the joint sitting by a majority of the total number of members of both Houses present and voting. That is a simple majority, and the device favours the Lok Sabha only because it is the larger House, not because any special threshold applies.
• Options (b), (c) and (d) import majorities that belong elsewhere: a special majority of two thirds present and voting plus a majority of total membership governs constitutional amendment under Article 368, impeachment of the President and removal of judges, while an absolute majority of total membership is the requirement in a few specific provisions such as the resolution under Article 249. The governing principle is that the joint sitting is a mechanism for breaking a deadlock over an ordinary Bill, so no elevated threshold is appropriate; and a candidate should note the corollary that a Money Bill and a Constitution Amendment Bill can never go to a joint sitting, the first because the Rajya Sabha cannot block it and the second because Article 368 requires each House to pass it separately.

• Option (d) is correct. The Andaman and Nicobar Islands carry all three formations within a small area: extensive mangrove along the tidal creeks, most famously at Baratang and in the Middle Andaman, tropical wet evergreen forest in the interior of the high rainfall islands, and moist deciduous forest with Andaman padauk on the drier and more disturbed tracts. High rainfall, an equable maritime climate and a broken tidal coastline are what allow the three to sit together.
• Option (a) is wrong: north coastal Andhra Pradesh has mangrove in the Godavari and Krishna deltas and moist to dry deciduous forest inland, but no true tropical evergreen forest.
• Option (b) is wrong: the Sundarbans mangrove lies in the south of West Bengal, and the state's forests are otherwise sal deciduous, evergreen forest being confined to the far north in the Terai and Dooars foothills rather than to the south west, whose Jangalmahal tract is dry deciduous.
• Option (c) is wrong: southern Saurashtra is a semi arid tract with thorn and scrub forest and small mangrove patches in the Gulf of Kachchh, and Gir is dry deciduous. The elimination route is the requirement of evergreen forest, which needs rainfall above about 2000 millimetres and eliminates three of the four regions at once.

• Option (b) is correct. The Montreal Protocol on Substances that Deplete the Ozone Layer, agreed in 1987 under the Vienna Convention of 1985, sets binding phase out schedules for chlorofluorocarbons, halons, carbon tetrachloride, methyl chloroform and the hydrochlorofluorocarbons that replaced them, with differentiated timelines and a Multilateral Fund for developing country Parties. It is the only environmental treaty with universal ratification and the only one whose phase out targets have been substantially met.
• Option (a) is wrong: Bretton Woods in 1944 created the International Monetary Fund and the International Bank for Reconstruction and Development.
• Option (c) is wrong: the Kyoto Protocol of 1997 sets greenhouse gas emission targets under the climate convention, a separate problem with separate chemistry.
• Option (d) is wrong: the Nagoya Protocol of 2010 governs access to genetic resources and benefit sharing under the Convention on Biological Diversity. Note for teaching that the two protocols in options (b) and (c) met at the Kigali Amendment of 2016, which brought hydrofluorocarbons, potent greenhouse gases with no ozone effect, under the Montreal Protocol precisely because its compliance machinery works better.

• Statement 1 is incorrect. Gunpowder and firearms were known and used in the subcontinent well before 1526: cannon and handguns appear in the Bahmani and Vijayanagara wars and in Gujarat and Malwa through the fifteenth century, and Babur's advantage at Panipat lay not in introducing gunpowder but in the tactical system he brought from Central Asia, the tulughma flanking manoeuvre combined with the araba, carts chained together to shield field artillery served by Ustad Ali Quli and Mustafa Rumi.
• Statement 2 is incorrect. The true arch and the dome entered Indian building with the Turkish conquest at the end of the twelfth century; the Qutb complex, the Alai Darwaza of 1311 and the tombs of the Tughlaqs and Lodis all precede Babur by two to three centuries.
• Statement 3 is correct. Babur was a Timurid in the male line, descended from Timur through Miran Shah and from Chingiz Khan through his mother, and his victory established the Timurid house in India, which is why the dynasty called itself Gurkani and only outsiders called it Mughal. The official answer (b) follows. Elimination route: the Lodi and Sayyid tombs standing in Delhi are enough to reject statement 2, which removes options (a) and (d), and the pre Panipat use of artillery removes (c). The governing principle is that a question crediting a founder with introducing what his predecessors already had is usually testing continuity against rupture.

• Option (d) is correct. The National Institution for Transforming India was constituted by a Cabinet resolution of 1 January 2015 in place of the Planning Commission, which had itself been set up by a Cabinet resolution in March 1950 and had no constitutional or statutory basis. The change was one of function as much as of name: NITI Aayog has no power to allocate plan funds to States, that function having passed to the Finance Commission route and to the ministries, and it is designed as a policy think tank operating on cooperative federalism through the Governing Council of Chief Ministers.
• Option (b) is the intended trap and is wrong for a reason worth teaching: the Finance Commission is a constitutional body under Article 280, appointed every five years, and cannot be replaced by executive resolution.
• Options (a) and (c) name bodies untouched by the reform, the National Human Rights Commission being statutory under the Protection of Human Rights Act 1993 and the Law Commission being a non statutory executive body. The elimination route is that only one of the four bodies was non statutory and non constitutional, and that is precisely why only it could be abolished this way.

• Option (a) is correct. Rio+20 is the United Nations Conference on Sustainable Development held at Rio de Janeiro in June 2012, twenty years after the Earth Summit of 1992 at the same city, from which the name is formed. Its outcome document, The Future We Want, launched the process that produced the Sustainable Development Goals, endorsed the green economy as a means to sustainable development and poverty eradication, and agreed to strengthen the United Nations Environment Programme and to replace the Commission on Sustainable Development with the High Level Political Forum.
• Option (b) is wrong: World Trade Organization ministerials are named for their venues, Doha, Bali, Nairobi.
• Option (c) is wrong: the Intergovernmental Panel on Climate Change assesses science and does not hold conferences of this kind, its outputs being assessment reports.
• Option (d) is wrong: the Convention on Biological Diversity meets as a Conference of the Parties numbered serially. The elimination route is the name itself, which anchors the meeting to Rio 1992 and therefore to the sustainable development track rather than to trade, to the climate science panel or to a single convention.

• Statement 1 is incorrect and is settled by the text: Article 53(1) vests the executive power of the Union in the President, to be exercised by him directly or through officers subordinate to him in accordance with the Constitution. The Prime Minister heads the Council of Ministers which under Article 74 aids and advises the President, and that advice is binding after the Forty second and Forty fourth Amendments, so the political reality is that the Prime Minister exercises the power, but the constitutional vesting is in the President and the statement asserts the vesting.
• Statement 2 is incorrect. The Civil Services Board, constituted in the wake of the Supreme Court's direction in T. S. R. Subramanian in 2013 to insulate transfers and postings, is chaired by the Cabinet Secretary at the Union level and by the Chief Secretary in the States. The body the Prime Minister does chair is the Appointments Committee of the Cabinet, which is the source of the confusion. The official answer (d) follows. Elimination route: Article 53 alone removes options (a) and (c), leaving a choice between (b) and (d) that turns on the Civil Services Board.

• Option (c) is correct. The Goldilocks Zone, more formally the circumstellar habitable zone, is the range of orbital distances from a star within which the stellar flux received by a planet would allow liquid water to persist on its surface given adequate atmospheric pressure, neither so close that water is lost to a runaway greenhouse nor so far that it freezes. The name is from the fairy tale, the porridge being neither too hot nor too cold. Its boundaries depend on stellar luminosity and temperature, so the zone lies closer in for a cool M dwarf and further out for a hotter star, and it is the standard criterion applied when a transiting exoplanet is reported as potentially Earth like.
• Option (a) is wrong and inverts the concept, which concerns distance from a star, not altitude above a planet.
• Option (b) is wrong: shale gas occurrence is governed by the thermal maturity window for hydrocarbon generation, a different idea although also a zone defined by temperature.
• Option (d) is wrong: there is no such usage in meteoritics. Elimination route: the term recurs in exoplanet reporting, and only option (c) concerns other planets.

• Option (b) is correct. C. Rajagopalachari led the Vedaranyam salt satyagraha, marching about 150 miles from Tiruchirappalli to Vedaranyam on the Tanjore coast in April 1930 and breaking the salt law there, the southern counterpart of Gandhi's march to Dandi and the principal Civil Disobedience action in the Madras Presidency. Sardar Vallabhbhai Patel's Dharasana and K. Kelappan's Payyannur actions belong to the same pattern of regional salt marches.
• Option (a) is wrong: V. O. Chidambaram Pillai belongs to the Swadeshi phase of 1905 to 1908, when he founded the Swadeshi Steam Navigation Company against the British India Steam Navigation monopoly, and he was imprisoned and broken well before 1930.
• Option (c) is wrong on chronology of leadership: K. Kamaraj participated in the Civil Disobedience Movement but was a younger worker who rose to prominence in the Congress organisation later, and he did not lead this march.
• Option (d) is wrong: Annie Besant led the Home Rule agitation of 1916, had by 1930 moved away from the Congress mainstream over the Nehru Report and the Commonwealth of India Bill, and took no part in salt satyagraha. The elimination route is chronological, since two of the four names are firmly attached to earlier phases.

• Option (c) is correct. Harihara I, with his brother Bukka, founded Vijayanagara in 1336 on the south bank of the Tungabhadra, a tributary of the Krishna, and the dynasty ruled in the name of the god Virupaksha of Hampi, the Sangama rulers signing their inscriptions and copper plate grants with the deity's name and describing themselves as ruling on his behalf, the land south of the Krishna being held to belong to him. Their guru Vidyaranya is credited in tradition with directing the enterprise.
• Option (a) is wrong: Amoghavarsha I was the Rashtrakuta ruler who built Manyakheta on the Kagina and wrote the Kavirajamarga, and the Rashtrakuta heartland lay north of the Krishna.
• Option (b) is wrong: Ballala II was a Hoysala of Dwarasamudra, modern Halebidu, in the twelfth century, and founded no such city.
• Option (d) is wrong: Prataparudra II was the last major Kakatiya of Warangal, defeated by the Delhi Sultanate in the 1320s, whose fall is part of the background to the rise of Vijayanagara rather than its cause. The elimination route is the phrase south bank of a tributary of the Krishna together with a deity's agency, which together identify Vijayanagara and Virupaksha uniquely.

• Statement 1 is incorrect. The first woman President of the Indian National Congress was Annie Besant, who presided at the Calcutta session of 1917 at the height of the Home Rule agitation. Sarojini Naidu, who presided at Kanpur in 1925, was the first Indian woman to hold the office, and the omission of the word Indian is exactly what makes the statement false.
• Statement 2 is correct: Badruddin Tyabji, a Bombay barrister and later a judge of the Bombay High Court, presided over the third session at Madras in 1887, two years after the founding, and used the office to urge Muslim participation against Sayyid Ahmad Khan's advice to stay away. The official answer (b) follows. The governing principle is that a statement of a first is falsified by a single earlier instance, and candidates should hold the parallel pairs together: W. C. Bonnerjee first President, Badruddin Tyabji first Muslim President, Annie Besant first woman President, Sarojini Naidu first Indian woman President, George Yule first British President.

• Statement 1 is correct. The Green Climate Fund was established by decision of the Conference of the Parties at Cancun in 2010 to channel finance to developing countries for both mitigation and adaptation, with a stated aim of an even split between the two and a floor for the least developed countries, small island developing States and African States. It is the principal operating entity of the financial mechanism of the climate convention.
• Statement 2 is incorrect. The Fund was founded under the aegis of the United Nations Framework Convention on Climate Change and is accountable to and functions under the guidance of its Conference of the Parties; the United Nations Environment Programme, the Organisation for Economic Co-operation and Development, the Asian Development Bank and the World Bank had no founding role, although the World Bank serves as interim trustee and multilateral development banks are among its accredited implementing entities, which is the grain of truth the distractor is built on. The official answer (a) follows. Elimination route: the Fund is part of the climate convention architecture, alongside the Global Environment Facility, the Adaptation Fund and the Least Developed Countries Fund, so any statement placing its parentage outside the convention should be treated with suspicion.

• Option (c) is correct. The Indira Gandhi Prize for Peace, Disarmament and Development for 2014 was awarded to the Indian Space Research Organisation, the jury citing the Mars Orbiter Mission, which entered Martian orbit on 24 September 2014 at the first attempt and at a cost far below comparable missions, and ISRO's record of applying space technology to development ends in communications, remote sensing, weather forecasting and disaster warning. The prize is given annually by the Indira Gandhi Memorial Trust, and its earlier recipients include institutions as well as individuals.
• Options (a), (b) and (d) are all national scientific institutions of standing but none was the recipient. There is no elimination route beyond recall, and the year is the operative detail, which is what lifts the item above easy for a candidate who remembers the award but not its year.

• Statement 1 is correct. The Cabinet Mission of 1946, comprising Pethick-Lawrence, Stafford Cripps and A. V. Alexander, rejected the demand for a separate Pakistan and proposed instead a Union of India embracing British India and the princely states, with the Union confined to foreign affairs, defence and communications and all residuary powers vesting in the provinces, the provinces being free to form groups with their own executives and legislatures. That three tier arrangement is a federal, indeed confederal, scheme.
• Statement 2 is incorrect. The Mission proposed no change to the judicial structure; the enlargement of judicial power in this period belongs to the Government of India Act 1935, which created the Federal Court in 1937.
• Statement 3 is incorrect. Indianisation of the services was the subject of the Islington Commission of 1917 and the Lee Commission of 1924, which fixed recruitment ratios for the Indian Civil Service, and had nothing to do with the Cabinet Mission, whose business was the transfer of power and the framing of a constitution by an elected Constituent Assembly. The official answer (a) follows. Elimination route: statement 1 is secure and its acceptance removes options (b) and (d), after which the item turns on statement 3.

• Option (d) is correct. Namdapha National Park in Changlang district of Arunachal Pradesh rises from about 200 metres on the Noa-Dihing to 4571 metres at Dapha Bum, a vertical span of more than four kilometres within a single protected area, so its vegetation runs continuously from tropical evergreen through subtropical and temperate broadleaf and conifer forest to alpine meadow and permanent snow. It is also the only protected area in the world recorded as holding four large cats, the tiger, common leopard, clouded leopard and snow leopard, which is a direct consequence of that altitudinal range.
• Option (a) is wrong: Khangchendzonga in Sikkim reaches far greater absolute height but begins at about 1800 metres, so its lower limit is subtropical to temperate and it has no tropical belt.
• Option (b) is wrong for the same reason: Nanda Devi begins around 1800 metres in the Garhwal Himalaya.
• Option (c) is wrong: Neora Valley in the Kalimpong hills of West Bengal spans roughly 180 to 3200 metres, reaching temperate forest but not the permanent snow zone. The governing principle is that the question is really about amplitude of relief rather than about absolute altitude, and the park that starts lowest and finishes highest wins.

• Option (b) is correct. Amnesty International, founded in London in 1961 by the lawyer Peter Benenson after his appeal on behalf of two imprisoned Portuguese students, is a global movement of individual members campaigning against human rights violations, best known for its work on prisoners of conscience, the death penalty, torture and arbitrary detention, and for its annual reports on country conditions. It received the Nobel Peace Prize in 1977.
• Option (a) is wrong and describes the United Nations High Commissioner for Refugees; Amnesty is not part of the United Nations system and takes no government funding for its research and campaigning, that financial independence being central to its claim of impartiality.
• Option (c) is wrong and describes a development or relief organisation such as Oxfam.
• Option (d) is wrong and describes something like the International Committee of the Red Cross or Medecins Sans Frontieres, and it is wrong twice over, since Amnesty is neither inter-governmental nor medical. The elimination route is that only one option names human rights, which is the organisation's entire subject.

• Statement 1 is incorrect and states the opposite of feudalism. The Indian feudalism thesis associated with R. S. Sharma turns on the fragmentation of central authority: from the Gupta period land grants to brahmanas and to officials, made tax free and with administrative and judicial rights surrendered, transferred the state's revenue and coercive powers to intermediaries, producing a strong local and a weak central authority together with the decline of trade, of coinage and of towns.
• Statement 2 is correct: the defining institutional feature is an administrative structure resting on control over and possession of land rather than on a salaried bureaucracy paid in cash, service being remunerated by assignment of land revenue.
• Statement 3 is correct: the graded chain of subordination between a lord and his overlord, with obligations of military service and tribute running upward and protection running downward, is the relationship that gives feudalism its shape, mirrored in the samanta hierarchy of early medieval India. The official answer (b) follows. Elimination route: statement 1 is transparently contrary to the whole concept, and rejecting it removes options (a) and (d), after which the choice between (b) and (c) turns on statement 2, which is the least controversial proposition in the set.

• Option (d) is correct. The BioCarbon Fund Initiative for Sustainable Forest Landscapes is a multilateral trust fund managed by the World Bank, announced at the Warsaw climate conference in November 2013 with contributions from Norway, the United Kingdom, Germany and later the United States. It pays for verified emission reductions achieved across whole landscapes rather than single projects, addressing deforestation driven by agriculture, and works alongside the Bank's other carbon finance vehicles.
• Option (a) is wrong: the Asian Development Bank runs its own regional climate funds but not this one.
• Option (b) is wrong: the International Monetary Fund does no carbon finance at all, its mandate being macroeconomic stability.
• Option (c) is wrong: the United Nations Environment Programme is a normative and convening body and is a partner in UN-REDD, which is the alternative multilateral REDD channel and the near neighbour a candidate is likely to reach for. The elimination route, and the only reliable one here, is the governing principle that the World Bank is the trustee and manager of nearly the whole architecture of international carbon finance, including the Forest Carbon Partnership Facility at Q74 of this same paper, the Prototype Carbon Fund and the Climate Investment Funds. Without that principle the item is pure recall of an obscure fund and unanswerable.

• Option (c) is correct. India holds large coal reserves but very little of coking quality: the Jharia field is the principal source of prime coking coal and is depleted and afflicted by underground fires, and Indian coal generally carries high ash of the order of twenty to forty five percent because it was formed from drift deposits, which makes it unsuitable for the blast furnace route without washing and blending. Integrated steel plants therefore import metallurgical coal, mainly from Australia, and coking coal is consistently among India's largest bulk imports by value.
• Option (a) is wrong: saltpetre, potassium nitrate, belongs to the manufacture of gunpowder, fertilizer and glass and has no role in steelmaking.
• Option (b) is wrong: rock phosphate is a phosphatic fertilizer feedstock, in which India is indeed heavily import dependent, but it is not a steel input, and it is here to catch the candidate who remembers the import dependence without remembering the industry.
• Option (d) fails once either of the first two is rejected. The governing distinction is between the quantity of a resource and its quality, India's coal problem being one of grade rather than of volume.

• Option (a) is correct. The Fifth Schedule, under Article 244(1), governs the administration of Scheduled Areas and Scheduled Tribes in States other than Assam, Meghalaya, Tripura and Mizoram, providing for a Tribes Advisory Council, for the Governor's power to direct that a law of Parliament or the State legislature shall not apply or shall apply with modifications, and for regulations on land transfer and moneylending. The Sixth Schedule, under Articles 244(2) and 275(1), provides for the administration of tribal areas in those four north eastern States through Autonomous District and Regional Councils with legislative, executive, judicial and financial powers. Both therefore exist to protect tribal interests, differing in the degree of self government conferred.
• Option (b) is wrong: State boundaries are altered under Article 3 by ordinary law.
• Option (c) is wrong: Panchayat powers are in Part IX and the Eleventh Schedule, and their extension to Scheduled Areas is by the separate PESA Act of 1996.
• Option (d) is wrong: the Schedules attach to tribal areas, which are not coterminous with border States, and several Fifth Schedule States are landlocked interior States. The elimination route is that the word Scheduled in Scheduled Areas points directly at Scheduled Tribes.

• Statement 1 is incorrect. The Union Budget is prepared by the Budget Division of the Department of Economic Affairs in the Ministry of Finance. The Department of Revenue administers direct and indirect taxation through the two Boards and contributes the revenue estimates, but it does not prepare the Budget, and the distinction between the department that raises revenue and the department that frames the Budget is the point of the statement.
• Statement 2 is correct: Article 266(3) provides that no moneys out of the Consolidated Fund of India shall be appropriated except in accordance with law and for the purposes and in the manner provided in the Constitution, which is given effect through the Appropriation Act passed each year.
• Statement 3 is incorrect and is the discriminating statement. The Public Account, under Article 266(2), holds moneys received by or on behalf of the Government of India in trust, such as small savings, provident funds and deposits, where the government acts as banker rather than owner; payments out of it are made by executive action without parliamentary appropriation, precisely because the money is not the government's own. The official answer (c) follows. Elimination route: rejecting statement 1 removes options (a) and (d), and the item then turns entirely on the Public Account, which is why it sits at the difficult end despite two of its three statements being straightforward.

• Option (d) is correct. The Supreme Court is the custodian and final interpreter of the Constitution: it exercises judicial review over legislative and executive action, enforces fundamental rights under Article 32, which Ambedkar called the heart and soul of the Constitution, decides disputes between the Union and the States under Article 131, and holds under the basic structure doctrine of Kesavananda Bharati that even the amending power in Article 368 cannot destroy the Constitution's essential features.
• Option (a) is wrong on a distinction worth holding: the President takes an oath under Article 60 to preserve, protect and defend the Constitution, which is a duty of office, but custodianship in the sense of authoritative protection through interpretation is judicial, and the President acts on ministerial advice.
• Option (b) is wrong: the Prime Minister heads the political executive, whose acts are themselves subject to review.
• Option (c) is wrong: the Lok Sabha Secretariat is an administrative body serving the House. The governing principle is that in a Constitution with an enforceable bill of rights and a written distribution of powers, custodianship necessarily rests with the organ empowered to strike down what is inconsistent with it.

• Statement 1 is incorrect in its beneficiary rather than in its date. The Accelerated Irrigation Benefits Programme was indeed launched in 1996-97, but the assistance went to State governments, as central loan assistance and later as grant, in order to complete large major and medium irrigation projects that had been left unfinished for want of State resources; it was never a credit line to poor farmers.
• Statement 2 is correct. The Command Area Development Programme was launched in 1974-75 to bridge the persistent gap between irrigation potential created and potential actually utilised, by taking the water the last distance from the outlet to the field through field channels, land levelling, warabandi rotational supply and on farm development, all of which are water use efficiency measures; it was restructured as the Command Area Development and Water Management Programme in 2004. The official answer (b) follows. There is no elimination route: a candidate must judge both statements independently, and statement 1 is dangerous because the date is right and only the beneficiary is wrong, which is the hardest kind of half true statement to catch under time pressure.

• Option (c) is correct. The Genetic Engineering Appraisal Committee functions under the Ministry of Environment, Forest and Climate Change, constituted under the Rules for the Manufacture, Use, Import, Export and Storage of Hazardous Micro-organisms, Genetically Engineered Organisms or Cells of 1989, which were framed under the Environment (Protection) Act 1986. It is the apex body for approving the environmental release of genetically engineered organisms and for large scale use in research, and it sits above the Institutional Biosafety Committees and the Review Committee on Genetic Manipulation in the Department of Biotechnology.
• Option (a) is wrong: the Food Safety and Standards Authority regulates genetically modified food as a food product once approved, a downstream and separate function.
• Option (b) is wrong: geographical indications are an intellectual property regime with no biosafety role.
• Option (d) is wrong: the Wild Life (Protection) Act deals with species protection and hunting. The elimination route is the governing principle that the release of a living modified organism into the environment is an environmental risk question, so the enabling statute must be the environmental one.

• Option (b) is correct. Basel III is the set of prudential standards issued by the Basel Committee on Banking Supervision from 2010 in response to the failures exposed by the global financial crisis. It raises both the quantity and the quality of regulatory capital, requiring a higher common equity tier one ratio and adding a capital conservation buffer and a countercyclical buffer, introduces a non risk based leverage ratio as a backstop against the gaming of risk weights, and for the first time sets global liquidity standards through the Liquidity Coverage Ratio and the Net Stable Funding Ratio.
• Option (a) describes the Convention on Biological Diversity and its national biodiversity strategies.
• Option (c) describes the Kyoto Protocol.
• Option (d) describes the Multilateral Fund under the Montreal Protocol. The elimination route is nomenclature: Basel is the seat of the Bank for International Settlements, and the Basel Convention, which shares the city's name, concerns transboundary movement of hazardous waste and is not among the options. The distinction worth teaching is that Basel II failed because it let banks measure their own risk while Basel III adds floors, buffers and liquidity rules that do not depend on the bank's own model.

• Statement 1 is incorrect as written. The westerlies are the prevailing winds of the mid latitudes, blowing from the subtropical high towards the subpolar low and deflected eastward by the Coriolis force, and they occupy roughly thirty to sixty degrees in each hemisphere separately, that is, thirty to sixty degrees North and thirty to sixty degrees South. The belt described in the statement, running from thirty degrees North across the equator to sixty degrees South, would swallow both trade wind belts and the equatorial trough, where the winds are easterly or calm.
• Statement 2 is correct. Winter rain over Punjab, Haryana, western Uttar Pradesh and Jammu and Kashmir is brought by western disturbances, extratropical low pressure systems that form over the Mediterranean and the Caspian region and are steered across Iran, Afghanistan and Pakistan into north western India by the subtropical westerly jet stream, which shifts south of the Himalaya in winter. That rain matters out of proportion to its quantity because it falls on the standing rabi wheat crop. The official answer (b) follows. Elimination route: statement 2 is standard monsoon material, and its acceptance removes options (a) and (d).

• Statement 1 is incorrect on both limbs. The association was established at Mauritius in March 1997, following the initiative taken after Nelson Mandela's visit to India in 1995, so it is not recent; and its founding impulse was economic regionalism in the Indian Ocean rim, trade facilitation and investment, not piracy or oil spills, the Somali piracy surge belonging to the late 2000s and postdating the body by a decade.
• Statement 2 is incorrect. Maritime safety and security is one of its priority areas, but the association's agenda covers trade and investment facilitation, fisheries management, disaster risk management, academic and science cooperation, tourism and the blue economy, so it is not a security alliance and is not confined to security. The official answer (d) follows. Elimination route: the words very recently in statement 1 and only in statement 2 are both absolutes, and a candidate with even an approximate sense of the body's date and breadth can reject both without precise recall.

• Option (a) is correct. The Swadeshi and Boycott movement launched against the partition of Bengal in 1905 forced open a division that had been latent since the 1890s: the extremists, led by Tilak, Lajpat Rai and Bipin Chandra Pal, wanted the boycott extended beyond Bengal and beyond foreign goods to a full programme of passive resistance and the declaration of swaraj as the goal, while the moderates under Gokhale and Pherozeshah Mehta wished to confine it to Bengal and to goods. The disagreement broke the Congress at the Surat session of December 1907, and the two wings reunited only at Lucknow in 1916.
• Options (b), (c) and (d) are all chronologically impossible as causes of this split, the Non-Cooperation Movement dating from 1920, Civil Disobedience from 1930 and Quit India from 1942, all after the reunion. The elimination route is therefore purely chronological, which makes this an item that rewards a secure timeline more than any detailed knowledge of the dispute.

• Option (a) is correct. The living root bridges, jingkieng jri, are built by the Khasi and Jaintia communities of Meghalaya in the Cherrapunji and Mawlynnong belt of the East Khasi Hills, by training the secondary aerial roots of the rubber fig, Ficus elastica, across a stream, often guided along a hollowed betel trunk, until they take hold on the far bank and thicken. Because the structure is alive it strengthens with age rather than decaying, which is the decisive detail in the stem, and it survives conditions that destroy timber and steel, this being among the wettest places on earth with annual rainfall of the order of eleven thousand millimetres.
• Options (b), (c) and (d) name regions with no such practice, and the ecology rules them out independently: Ficus elastica is a tree of the warm wet tropics, so the temperate Himachal hills cannot support it, and neither Jharkhand nor Tamil Nadu has the rainfall regime that makes the technique necessary or possible. The governing principle for the candidate is that the answer follows from rainfall, since only the north eastern hills combine extreme precipitation with steep stream crossings.

• Option (d) is correct. IndARC is India's first multi-sensor moored observatory in the Arctic, deployed in July 2014 by the Ministry of Earth Sciences through the National Centre for Antarctic and Ocean Research at a depth of about 192 metres in Kongsfjorden, a fjord off Ny-Alesund in Svalbard. Its sensors record temperature, salinity, currents and ocean acidification through the year, including the polar winter when ships cannot reach the site, and the scientific purpose is to understand Arctic processes and their teleconnection with the Indian monsoon.
• Option (c) is the intended trap and inverts the pole: India's Antarctic stations are Maitri and Bharati, the earlier Dakshin Gangotri having been abandoned to ice, while India's Arctic presence is the Himadri station at Ny-Alesund, established in 2008, of which IndARC is the oceanographic extension.
• Option (a) is wrong: the indigenous radar family carries names such as Rajendra, Revathi and Indra.
• Option (b) is wrong: the regional satellite of that description is the South Asia Satellite, and it postdates this paper. Elimination route: the syllable ARC in the name points at the Arctic and not at the Antarctic, which is the single clue that separates option (d) from option (c).

• Statement 1 is correct. The Forest Carbon Partnership Facility, launched at the Bali climate conference in 2007 and operational from 2008, is a World Bank administered partnership whose participants include donor and forest country governments, private sector entities, non-governmental organisations and indigenous peoples' organisations, the last having a formally recognised place in its governance because forest carbon programmes turn on the rights of forest dwelling communities.
• Statement 2 is incorrect: the Facility does not fund academic research, individual scientists or technology development, and the description belongs to a research grant body rather than to a carbon finance instrument.
• Statement 3 is correct: the Facility operates a Readiness Fund, which helps countries build reference emission levels, monitoring, reporting and verification systems and safeguard frameworks, and a Carbon Fund, which pays for verified emission reductions once readiness is achieved. The official answer (c) follows. Elimination route: statement 2 is out of character for the instrument, and rejecting it removes options (b) and (d), while statement 3 restates what REDD plus support means and removes (a). The governing principle is the one that also settles Q56 of this paper, that international forest carbon finance runs through the World Bank and pays for measured outcomes rather than for research.

• Option (a) is correct on the position when the paper was set. Odia was declared a classical language in February 2014, becoming the sixth after Tamil in 2004, Sanskrit in 2005, Kannada and Telugu in 2008 and Malayalam in 2013, and the first from the Indo-Aryan family. The criteria applied at the time required high antiquity of early texts over a period of fifteen hundred to two thousand years, a body of ancient literature regarded as a valuable heritage by generations of speakers, an original literary tradition not borrowed from another speech community, and a discontinuity between the classical language and its modern form.
• Option (b) is wrong: Konkani is a scheduled language and the official language of Goa but held no classical status.
• Option (c) is wrong: Bhojpuri was not then even in the Eighth Schedule, and its inclusion has been a standing demand.
• Option (d) is wrong on the position in 2015. The elimination route is that the recognition was granted to a language with a documented literary corpus running back to the medieval period, which excludes Bhojpuri at once.

• Statement 1 is correct. BirdLife International is a global partnership of national conservation organisations, one per country or territory, of which the Bombay Natural History Society is the Indian partner.
• Statement 2 is incorrect and is the discriminating statement. The biodiversity hotspot concept was formulated by the British ecologist Norman Myers in 1988 and refined with Conservation International in 2000, the criteria being at least fifteen hundred endemic vascular plant species and the loss of at least seventy percent of original primary vegetation. BirdLife's own analogous contribution is the Endemic Bird Area, which is a different construct.
• Statement 3 is correct: BirdLife identifies and maintains the global inventory of Important Bird and Biodiversity Areas, using standardised criteria on globally threatened species, restricted range species, biome restricted assemblages and congregations, and it is also the Red List authority for birds on behalf of IUCN, which is the fact that gives it its standing. The official answer (c) follows. Elimination route: attributing hotspots to Myers and Conservation International removes options (b) and (d), and statement 1 is uncontroversial, which removes (a).

• Option (a) is correct. Teak, Tectona grandis, is the characteristic dominant of the tropical moist deciduous formation, which occupies areas receiving roughly 100 to 200 centimetres of annual rainfall with a marked dry season, in the Western Ghats, the Satpura and Maikal ranges, central India and parts of the Deccan, and its leaf fall during the dry months is the defining adaptation of the deciduous habit. Sal, Shorea robusta, is the corresponding dominant of the eastern and northern moist deciduous tracts, and the two rarely overlap.
• Option (b) is wrong: tropical rain forest is evergreen and dominated by dipterocarps and other tall buttressed hardwoods with no synchronised leaf fall, and teak cannot compete there.
• Option (c) is wrong: the thorn and scrub formation of the arid tracts is dominated by acacias, Prosopis and Capparis, and teak needs far more moisture.
• Option (d) is wrong: temperate forests lie in the Himalaya and carry oak, deodar, pine and fir. The governing principle is that deciduousness is a drought adaptation, so the tree defining the formation must be found where the year is divided into a wet and a dry season, which is what excludes both the always wet and the always dry options.

• Option (c) is correct. The Beijing Declaration and Platform for Action was adopted unanimously by 189 states at the Fourth World Conference on Women, convened by the United Nations at Beijing in September 1995, and remains the most comprehensive international agenda for women's empowerment. It identifies twelve critical areas of concern, among them poverty, education, health, violence against women, armed conflict, the economy, power and decision making, human rights, the media, the environment and the girl child, and it introduced gender mainstreaming as the strategy to be applied across all policy.
• Options (a), (b) and (d) each attach a plausible subject to a plausible forum and are wrong on both limbs; the Shanghai Cooperation Organization's counter terrorism instrument is the Shanghai Convention of 2001, and its regional structure sits at Tashkent. The elimination route is the association of Beijing 1995 with the women's conference, which is one of the four United Nations world conferences on women, after Mexico City in 1975, Copenhagen in 1980 and Nairobi in 1985.

• Option (b) is correct. The passage describes the diurnal convectional regime of the equatorial climate. Intense insolation on a nearly vertical Sun heats a humid surface, air rises in strong convection currents through the day, towering cumulonimbus builds by early afternoon, and a violent but short lived thunderstorm follows, often called the four o'clock rain, after which the sky clears. The decisive words are each day is more or less the same: the equatorial belt has small annual range of temperature, rain in every month and effectively no seasons, only a daily rhythm, and the writer describes a day rather than a season for that reason.
• Option (a) is wrong: the savannah has a sharply marked wet and dry season, so no day can stand for the year.
• Option (c) is wrong for the same reason, the monsoon being defined by seasonal reversal of wind and a long dry season.
• Option (d) is wrong: the Mediterranean regime has dry warm summers and wet mild winters, and its summer is the season of drought, not of daily thunderstorms. The governing principle is that a passage describing a typical day rather than a typical year can only describe a climate without seasons.

• Statement 1 is incorrect. Real growth over the decade preceding the paper was anything but steady: it ran above nine percent in the three years to 2007-08, fell to about six and seven tenths percent in the crisis year 2008-09, recovered above eight percent in 2009-10 and 2010-11, and then slid to roughly five percent in 2012-13 before recovering. The word steadily requires monotonic increase, which no series of this kind exhibits, and business cycles guarantee that it will not.
• Statement 2 is correct. Gross domestic product at market prices measured in current rupees rose every year across the decade, because the nominal series is the product of real output and the price level, and with inflation positive throughout, nominal output rises even in a year when real growth decelerates, and would fall only in an outright contraction deep enough to outweigh inflation. The official answer (b) follows. The governing distinction, and the whole substance of the item, is between a real series measured at constant prices, which can fall and does fluctuate, and a nominal series at current prices, which incorporates inflation and therefore almost never falls. Elimination route: recognising statement 1 as an absolute claim about a cyclical variable removes options (a) and (c).

• Statement 1 is incorrect. Article 171(1) provides that the total number of members in the Legislative Council of a State shall not exceed one third of the total number of members in the Legislative Assembly of that State, with a floor of forty members, so a Council can never be as large as half the Assembly. The composition is also fixed: about one third elected by local authorities, one twelfth by graduates of three years standing, one twelfth by teachers of three years standing in institutions not lower than secondary, one third by members of the Assembly from outside the Assembly, and the remainder nominated by the Governor from persons with special knowledge of literature, science, art, cooperative movement and social service.
• Statement 2 is incorrect. The Chairman and Deputy Chairman of the Legislative Council are elected by the Council from among its own members, under Article 182, and the Governor has no role. The confusion is with the Rajya Sabha, whose Chairman is the ex officio Vice President and therefore not a member of the House, a design the States do not follow. The official answer (d) follows. Elimination route: the one third ceiling is standard and removes options (a) and (c), leaving the item to turn on Article 182.

• Option (d) is correct. The words quoted are Article 51A(c), which makes it the duty of every citizen of India to uphold and protect the sovereignty, unity and integrity of India. The Fundamental Duties were inserted by the Forty second Amendment of 1976 on the recommendation of the Swaran Singh Committee, and a matter of drafting worth noting is that the duties are addressed to the citizen, whereas Directive Principles are addressed to the State, which by itself resolves the item once the language of duty is recognised.
• Option (a) is the intended trap and is a near miss rather than a wild distractor: the Preamble, as amended in 1976, does speak of assuring the unity and integrity of the Nation, and describes India as a sovereign republic, but it nowhere uses the operative words uphold and protect, and it imposes no obligation on anyone.
• Option (b) is wrong: the closest Directive Principles are Articles 51 and 38, neither of which uses this formula.
• Option (c) is wrong: Part III confers rights against the State, and imposes no duty of this kind on citizens. The governing principle is that the grammar of the provision, a duty to do something, locates it in Part IVA.

• Option (c) is correct. An ecosystem, in Tansley's formulation of 1935, is the biotic community together with its physical environment considered as one interacting system, the essential point being the coupling of the living and the non living through energy flow and nutrient cycling. Remove the abiotic component and the concept collapses, because the transfer of energy through trophic levels and the cycling of carbon, nitrogen and phosphorus all pass through the physical environment.
• Option (a) describes the biotic community alone, which is a component of an ecosystem and not the whole of it.
• Option (b) describes the biosphere, the global sum of all ecosystems, and is a matter of scale rather than of definition.
• Option (d) describes the biota of an area, a taxonomic inventory that captures neither the interactions nor the environment. The elimination route is to look for the option that names both the organisms and their surroundings, since only one does, and the word best in the stem signals that more than one option will be partially true.

The key takes items 1 and 3, giving option (c). Popular participation in development and democratic decentralisation are the two ideas that run through the whole lineage of Panchayati Raj, from the Balwantrai Mehta Committee of 1957, which framed it as democratic decentralisation to make community development work, through the Ashok Mehta Committee of 1978 and the L. M. Singhvi Committee of 1986, to the Seventy third Amendment of 1992, whose Article 243G contemplates panchayats as institutions of self government preparing plans for economic development and social justice.

• Item 2 is excluded as being political accountability of representatives to the electorate, which is a feature of every representative institution rather than a fundamental object peculiar to Panchayati Raj.
• Item 4 is excluded because financial mobilisation is a means and a persistent weakness rather than an object; panchayats depend overwhelmingly on devolved and tied funds, which is the standing criticism of the system. There is no clean elimination route, and the item requires the candidate to distinguish an object from a mechanism.

• Items 1 and 2 are components of monetary policy, so the official answer is (c). The bank rate is the rate at which the central bank stands ready to lend to banks against eligible securities without repurchase agreement, and it functions as the penal rate for shortfalls in reserve maintenance; open market operations are the outright purchase and sale of government securities by the Reserve Bank to inject or absorb durable liquidity. Both are instruments in the hands of the monetary authority.
• Items 3 and 4 belong to fiscal policy, which is the domain of the government rather than of the central bank: public debt is the accumulated borrowing of the government and public revenue its tax and non tax receipts. The governing distinction is one of authority and of instrument, monetary policy operating on the quantity and price of money through a central bank, fiscal policy operating on public spending, taxation and borrowing through the Budget. The point of overlap worth flagging to students is that open market operations are conducted in government securities, so the instrument is monetary even though the paper traded is a fiscal liability, and it is that overlap the item is testing.

• Option (c) is correct. Inflation in its demand pull form arises when money supply and aggregate demand run ahead of the economy's capacity to produce, so contracting the quantity of money in circulation, by raising policy rates, raising reserve requirements or selling securities in the open market, reduces demand pressure and moderates the rise in the price level.
• Option (d) states the opposite and is self evidently wrong.
• Options (a) and (b) are complements of one another and both fail, which is itself the clue: inflation control in India is a shared responsibility, the Reserve Bank acting through monetary policy and the government through fiscal policy, supply management, buffer stock operations and administered prices, so neither can be the responsibility of one alone. The elimination route is to notice that (a) and (b) cannot both be false unless both are, and that (c) and (d) are contradictories of which exactly one must be true, so the item reduces to a single judgement about the direction of the effect.

• Option (b) is correct. The welfare state ideal is carried by Part IV, and specifically by Article 38, which directs the State to secure a social order in which justice, social, economic and political, shall inform all the institutions of national life and to minimise inequalities in income, status, facilities and opportunities, and by Article 39, which lays down the principles of adequate means of livelihood, distribution of material resources to subserve the common good, prevention of concentration of wealth, equal pay for equal work and protection of children and workers. Articles 41 to 47 add work, education, public assistance, living wages, nutrition and public health.
• Option (a) is a plausible near miss: the Preamble speaks of justice, liberty, equality and fraternity and, after 1976, of a socialist republic, but it is a declaration of purpose and creates no directive to the State.
• Option (c) is wrong: Fundamental Rights are principally restraints on State action and are negative in structure, though the Supreme Court has read welfare content into Article 21 through the right to livelihood, health and shelter, which is the qualification worth teaching alongside this item.
• Option (d) is wrong: the Seventh Schedule distributes legislative subjects. The governing distinction is between a statement of aspiration in the Preamble and an enforceable direction of policy in Part IV.

• Option (b) is correct on the classification used in growth theory. Technological progress is described as factor augmenting according to which input its effectiveness is raised. Writing output as a function of labour and capital in efficiency units, labour augmenting or Harrod neutral progress raises the effectiveness of each worker, while capital augmenting or Solow neutral progress raises the effectiveness of each unit of capital. A plough is a capital good, and replacing wood with steel leaves the number of workers and the number of ploughs unchanged while making each plough do more work, so the improvement is embodied in the capital stock and is capital augmenting.
• Option (a) is wrong on that reasoning, although it is the natural intuitive answer, since output per worker plainly rises; the point is that the rise comes through the improved implement rather than through any change in the worker's own productivity, and the same reasoning distinguishes a better machine from better training.
• Option (c) is wrong: capital reducing progress would allow the same output with less capital, whereas here the capital is improved rather than economised.
• Option (d) fails once (b) is established. There is no elimination route and the item is a straight test of a classification that sits outside most Prelims preparation.

• Option (d) is correct. The defining feature of the parliamentary or Westminster system is collective responsibility of the executive to the popularly elected chamber, and it is stated in Article 75(3), that the Council of Ministers shall be collectively responsible to the House of the People. Everything else follows from it: the government holds office only while it commands confidence, ministers are drawn from and answerable to the legislature, and the nominal and real executives are separated.
• Option (a) is wrong because direct election of the lower chamber is common to parliamentary and presidential systems alike, the United States House of Representatives being directly elected.
• Option (b) is wrong because the amending power says nothing about the relationship between executive and legislature; a presidential constitution can equally be amended by its legislature.
• Option (c) is wrong because a permanent upper chamber is a feature of bicameral design, again shared with presidential systems, and the United States Senate is likewise not subject to dissolution. The governing principle for eliminating is to ask which feature would disappear if India adopted a presidential system, and only responsibility to the legislature would.

• Option (d) is correct. H1N1 designates an influenza A subtype named for its surface glycoproteins, haemagglutinin type one and neuraminidase type one; the strain that caused the 2009 pandemic was a reassortant of swine, avian and human influenza genes and was accordingly called swine flu.
• Option (b) is the trap: avian influenza is also an influenza A virus, but the strains of concern carry different subtype designations, principally H5N1 and H7N9, and the H and N numbers are exactly what separate the two diseases.
• Option (a) is wrong: AIDS is caused by the human immunodeficiency virus, a retrovirus with a wholly different genome and mode of transmission.
• Option (c) is wrong: dengue is caused by a flavivirus transmitted by Aedes aegypti. The elimination route is that only two options name influenza at all, and the subtype numbering settles the choice between them. The point worth teaching is that influenza's segmented genome permits reassortment when two strains infect the same host, which is why pigs, susceptible to both avian and human strains, act as a mixing vessel and why new pandemic subtypes emerge from them.

• Statement 1 is incorrect. Decomposition in the railway bio-toilet is initiated by a bacterial inoculum, not a fungal one: the consortium developed by the Defence Research and Development Establishment at Gwalior was derived from anaerobic bacteria adapted to the cold of Antarctic conditions, and it comprises psychrophilic, mesophilic and thermophilic anaerobes working in series in a multi chamber retention tank.
• Statement 2 is incorrect. Anaerobic digestion of organic matter yields methane and carbon dioxide as the principal gases, together with water, and the treated effluent is chlorinated before discharge; ammonia and water vapour are not the only products, and the statement is also implausible on its face, since anaerobic breakdown of carbon rich material must produce a carbon bearing gas. The official answer (d) follows. Elimination route: the word only in statement 2 is the standard signal of an overstated claim, and the chemistry confirms it, so a candidate who is unsure about the inoculum can still reject statement 2 and narrow the field to (a) or (d).

• Option (c) is correct. International liquidity means the stock of internationally acceptable means of payment available to a country to settle external obligations, comprising foreign exchange reserves in hard currencies, gold, Special Drawing Rights and the reserve tranche position at the International Monetary Fund. A liquidity problem arises when a country cannot command enough widely accepted currency, principally the dollar and secondarily the euro, yen, pound and Swiss franc, to meet its import bill and debt service, which is precisely the situation India faced in 1991 with reserves covering about two weeks of imports.
• Option (b) is the near miss: gold remains a reserve asset and India did pledge gold in 1991, but since the collapse of the Bretton Woods gold convertibility in 1971 the international payments system has run on key currencies, and it is their availability that defines liquidity.
• Options (a) and (d) confuse a payments problem with a production problem; a country can have goods and an exportable surplus and still face a liquidity crisis if it cannot convert them into acceptable currency quickly enough, which is exactly why the crisis is one of timing and confidence rather than of real resources. The governing distinction is between solvency, the capacity to pay over time, and liquidity, the capacity to pay now.

• Statement 1 is correct. A hydrogen fuel cell oxidises hydrogen electrochemically rather than by combustion: hydrogen is oxidised at the anode, the electrons travel through the external circuit, and at the cathode oxygen combines with them and with the protons that have crossed the electrolyte to form water. Since the free energy change is not fully converted to electrical work, the balance appears as heat, so water and heat are the only by-products, and the absence of carbon in the fuel is why there is no carbon dioxide.
• Statement 2 is incorrect. Fuel cells scale across the whole range, from megawatt stationary installations down to portable units; direct methanol fuel cells were developed precisely for laptops and handheld devices, and the statement's restriction is false.
• Statement 3 is incorrect and is the cleanest elimination in the item. A fuel cell is an electrochemical cell and produces direct current by its nature, since the electrode reactions fix the polarity; an inverter must be added to supply alternating current to a grid or a building. The official answer (a) follows. Elimination route: the direct current point alone removes options (b), (c) and (d), so a candidate secure on that single fact answers the item without judging the other two statements.

• Option (a) is correct. Kalamkari is a textile art practised on cotton in Andhra Pradesh, the name coming from the kalam, the bamboo or date palm pen used to draw and to apply the mordants and dyes. It has two centres and two idioms: Srikalahasti, temple based and entirely freehand, depicting narrative panels from the epics and the Puranas for use as temple hangings, and Machilipatnam or Pedana, which uses carved wooden blocks and grew under Persian and Golconda patronage for export. The dyes are vegetable, and the sequence of washing, myrobalan treatment, drawing, mordanting and repeated washing runs to many stages.
• Options (b), (c) and (d) each get one element right and the rest wrong, which is the design of the item: the material must be cotton, not bamboo, wool or silk, and the region must be southern. The elimination route is the word kalam itself, a pen, which points to a drawn rather than a woven or block dyed craft and to the Deccan rather than the north.

• Option (b) is correct. The Seed Village Scheme addresses the low seed replacement rate in Indian agriculture, which arises because certified seed from the formal sector reaches only a minority of farmers while most sow retained grain of declining vigour. The scheme organises a cluster of farmers in a village, trains them in seed production, roguing, harvesting and storage, supplies foundation or certified seed at subsidy along with storage bins, and thereby creates a village level source of quality seed available to neighbouring farmers at the right time and at a price below the market. The essential idea is decentralised multiplication with training, so that quality seed travels a short distance rather than a long one.
• Option (a) is wrong and inverts the object: the scheme raises seed quality rather than encouraging farmers to fall back on their own retained seed.
• Option (c) is wrong: certified seed production is the business of seed corporations and licensed growers under certification agency supervision, and no village is earmarked exclusively for it.
• Option (d) is wrong: the scheme trains farmers, not entrepreneurs setting up companies. The elimination route is that only option (b) contains training, which is the operative mechanism.

• Items 1 and 3 hold the tag, so the official answer is (c). Banaras Brocades and Sarees were registered in 2009 in the handicrafts class, the registration covering the districts of Varanasi, Mirzapur, Chandauli, Bhadohi, Jaunpur and Azamgarh, and it was sought to protect the weavers against machine made and imported imitations. The Tirupathi Laddu was registered in the same period on the application of the Tirumala Tirupati Devasthanams, and the registration was contested on the ground that a temple offering distributed as prasadam is not a good in trade, which makes it the most instructive of the three for a candidate.
• Item 2 is incorrect: Rajasthani daal-bati-churma is a regional cuisine, not a product with a defined producer, place of origin and reputation attributable to that origin, and a dish cooked in every household of a State cannot satisfy the requirement that the qualities be essentially attributable to a delimited geographical area. The elimination route is that a home cooked dish is not the kind of thing the Act protects, and rejecting item 2 removes options (b) and (d), while the Banarasi saree is among the best known Indian registrations and removes (a).
