2014

• Statement 1 is correct. The Sustainable Sugarcane Initiative raises single-budded setts in a nursery and transplants young seedlings, so seed requirement falls from roughly six to eight tonnes of cane per hectare under the conventional three-budded sett method to about two tonnes, and seed cost falls with it.
• Statement 2 is correct. SSI plants at wide spacing, commonly about five feet between rows, on raised beds or ridges, and that geometry is precisely what makes drip laterals practicable and efficient; water saving of the order of thirty to forty per cent is the standard claim for the package.
• Statement 3 is incorrect. SSI reduces dependence on chemical fertiliser and emphasises organic manures, biofertilisers and soil health, but it does not exclude inorganic fertiliser altogether; it is a resource-efficiency package, not a certified organic system.
• Statement 4 is correct, and follows from the same wide spacing that permits drip: the inter-row space in the early months carries a short-duration intercrop such as pulses or vegetables. The official answer (b) therefore follows. The governing principle here is the absolute qualifier.
• Statement 3 says there is no application of chemical fertilisers 'at all', and an unqualified absolute of that kind is almost always the planted false statement. Recognising it settles the question outright, because (b) is the only option that omits statement 3 while retaining the others; (a), (c) and (d) all contain it.

• Option (a) is correct and is close to the operative words of the instrument itself. The Montreux Record, established by Recommendation 4.8 of the 1990 Conference of the Contracting Parties, is a register maintained as part of the Ramsar List on which are placed those listed sites where changes in ecological character have occurred, are occurring or are likely to occur as a result of technological developments, pollution or other human interference. Listing is voluntary, made with the agreement of the Contracting Party concerned, and is a flag for priority conservation attention rather than a sanction.
• Option (b) is incorrect. Neither the Ramsar Convention nor the Montreux Record prescribes any buffer distance, and the five kilometre figure is invented; buffer or eco-sensitive zone requirements in India arise under domestic environmental law, not under Ramsar.
• Option (c) is incorrect. It describes the reasoning behind cultural landscape protection and has nothing to do with the Record, although the Convention does recognise the wise use role of local communities.
• Option (d) is incorrect and tests a common confusion: Ramsar listing and World Heritage inscription are separate regimes under separate instruments, the latter administered by UNESCO under the 1972 Convention. A candidate who knows only that Ramsar and World Heritage are distinct can already discard (d), and the specificity of the phrase 'ecological character', which is the Convention's own term of art, points to (a).

• Option (a) is correct. The Ten Degree Channel, so named because it runs approximately along the parallel of ten degrees north, separates the Andaman group to the north from the Nicobar group to the south, and is about one hundred and fifty kilometres wide.
• Option (b) is incorrect. Nicobar is separated from Sumatra by the Great Channel, also called the Six Degree Channel, lying near six degrees north.
• Option (c) is incorrect. Lakshadweep is divided internally by the Eight Degree Channel, which separates Minicoy from the main Lakshadweep group, and by the Nine Degree Channel; the Eight Degree Channel also separates Minicoy from the Maldives.
• Option (d) is incorrect. Sumatra and Java are separated by the Sunda Strait, a tectonically active passage that contains Krakatoa. The elimination route is arithmetic rather than cartographic: the channels of this region are named for the latitudes they follow, so a candidate who fixes the approximate latitude of each pair can place the Ten Degree Channel without recalling the specific fact.

• Pair 1 is incorrectly matched. The Drought-Prone Area Programme, launched in 1973, was administered by the Department of Land Resources in the Ministry of Rural Development, not the Ministry of Agriculture.
• Pair 2 is incorrectly matched. The Desert Development Programme, launched in 1977 for hot and cold desert areas, was likewise a Department of Land Resources programme under the Ministry of Rural Development, not under the Ministry of Environment and Forests; the desert framing misleads candidates towards the environment ministry.
• Pair 3 is incorrectly matched, and it is the inversion of pair 1. The National Watershed Development Project for Rainfed Areas, launched in 1990-91, was run by the Department of Agriculture and Cooperation in the Ministry of Agriculture, not by the Ministry of Rural Development. All three are wrong, so the official answer is (d). The design of the item is a deliberate crossing: the two rural development programmes have been given to other ministries and the agriculture ministry programme has been given to rural development. A candidate who securely knows that the three watershed programmes of the Department of Land Resources were DPAP, DDP and the Integrated Wastelands Development Programme can reject pairs 1 and 2 at once, which removes (a) and (c), and is then left to decide pair 3 between (b) and (d).

• Statement 1 is incorrect. The Bombay Natural History Society, founded in 1883, is a non-governmental membership organisation registered as a society and a public charitable trust. It is not an autonomous body of the Ministry of Environment and Forests, although it is recognised by the Department of Science and Technology as a Scientific and Industrial Research Organisation and receives project funding from government. The distinction the examiner is testing is between an autonomous body created and funded by a ministry, such as the Wildlife Institute of India or the Indian Council of Forestry Research and Education, and an independent society that merely works with government.
• Statement 2 is correct, and reproduces the Society's own mission formula of conservation of nature through action-based research, education and public awareness.
• Statement 3 is correct. Nature trails, camps, birdwatching walks and the conservation education programme at Hornbill House and the Conservation Education Centre in Goregaon are among its best-known public activities. The official answer is therefore (c). The item is decided entirely on statement 1, and the elimination is clean, since rejecting statement 1 removes (a) and (d) at once and statements 2 and 3 are both unobjectionable descriptions of any conservation society.

• Option (a) is correct. The Global Environment Facility, established in 1991 in the run-up to the Rio Earth Summit and restructured in 1994, serves as the financial mechanism for five conventions: the Convention on Biological Diversity, the United Nations Framework Convention on Climate Change, the United Nations Convention to Combat Desertification, the Stockholm Convention on Persistent Organic Pollutants and, later, the Minamata Convention on Mercury.
• Option (b) is incorrect. The GEF is a funding institution, not a research institution. It disburses grants and concessional finance through implementing agencies such as UNDP, UNEP and the World Bank; scientific advice reaches it from its Scientific and Technical Advisory Panel, but the Facility does not itself conduct global environmental research.
• Option (c) is incorrect on two counts. The GEF is not an agency of the OECD; it is an independently governed partnership with the World Bank acting as trustee of its trust fund, and its governance is deliberately balanced between donor and recipient countries rather than confined to the donor club that the OECD represents.
• Option (d) fails because it depends on (b). The elimination route runs through the words 'financial mechanism'. Every convention that names a financial mechanism names the GEF, and once a candidate fixes the GEF as a funding body rather than a research body, (b), (c) and (d) all fall together.

• Statement 1 is correct and states the fundamental distinction between the two routes. Photovoltaic conversion is a quantum process: a photon of energy greater than the band gap generates an electron-hole pair in a semiconductor and the built-in field of the p-n junction separates the carriers, producing current without any intermediate thermal or mechanical stage. Solar thermal conversion is a heat-engine process: concentrating collectors raise a working fluid to high temperature, and the heat is converted to work in a Rankine or Brayton cycle and thence to electricity, so it is subject to the Carnot limit in a way photovoltaics is not.
• Statement 2 is incorrect, and is the inversion of the truth. A photovoltaic cell is a direct-current device; the current flows one way across the junction, and an inverter is needed before the output can be fed to the grid. Solar thermal plants drive a conventional synchronous turbo-alternator and therefore produce alternating current natively.
• Statement 3 is incorrect. In 2014 India had a substantial and long-established photovoltaic manufacturing base in cells and modules, dating to the 1980s, while its solar thermal manufacturing capability was thin and most concentrating solar power components for the Jawaharlal Nehru National Solar Mission projects were imported. The statement reverses the position. The official answer is therefore (a).
• Statement 2 is the decisive one and is settled by physics alone, with no recall of Indian industry required: rejecting it removes (b) and (c), and statement 1 is manifestly true, which removes (d).

• Pair 1 is correctly matched. Dampa Tiger Reserve lies in the Mamit district of western Mizoram along the Bangladesh border and is that State's largest protected area, notified as a tiger reserve in 1994.
• Pair 2 is incorrectly matched. The Gumti Wildlife Sanctuary is in Tripura, in the Gomati river catchment, and is known for its elephant and avifaunal populations; it has no connection with Sikkim, whose protected areas are Khangchendzonga, Fambong Lho, Maenam, Barsey Rhododendron, Kyongnosla and Shingba.
• Pair 3 is correctly matched. Saramati, at about three thousand eight hundred and forty metres, is the highest peak of Nagaland, standing on the border with Myanmar in the Naga Hills. The official answer is therefore (c). The item is decided on pair 2. Sikkim is a Himalayan State whose protected area names are almost all Tibetan or Lepcha in derivation, whereas Gumti is a Tripura river name, and that linguistic mismatch alone is enough to reject the pair, which removes (b) and (d). Dampa is the more commonly known of the remaining two, so a candidate confident of it reaches (c) without needing to place Saramati.

• Statement 1 is incorrect. Wetlands International is a global non-profit non-governmental organisation with its head office at Ede in the Netherlands, formed in 1995 from the merger of the International Waterfowl and Wetlands Research Bureau, the Asian Wetland Bureau and Wetlands for the Americas. It is not intergovernmental and was not created by the parties to the Ramsar Convention. It is, however, a formally recognised International Organisation Partner of the Ramsar Convention, alongside BirdLife International, IUCN, the International Water Management Institute and WWF, and it is this partner status that the examiner is inviting the candidate to over-read as membership.
• Statement 2 is correct and reproduces the organisation's own account of its method, which combines field programmes with the compilation of knowledge, notably the Waterbird Population Estimates series and the Asian Waterbird Census, and the use of that evidence in policy advocacy. The official answer is therefore (b). The governing distinction is between an intergovernmental organisation, established by treaty between States, and an international non-governmental organisation with which a treaty body chooses to work. A candidate who holds that distinction firmly can reject statement 1 without knowing anything specific about this body, and statement 2 is written in terms too general to be false.

• Statement 1 is incorrect. The first BRIC summit was held at Yekaterinburg in Russia in June 2009, not at Rio de Janeiro. Rio is a plausible distractor because Brazil is a founder member and because Rio hosted the 1992 Earth Summit and the 2012 Rio+20 conference, but the Brazilian summits of this grouping were Brasilia in 2010 and Fortaleza in 2014.
• Statement 2 was correct when the paper was set. South Africa was invited in December 2010, attended its first summit at Sanya in China in April 2011, and the acronym changed from BRIC to BRICS at that point. The official answer is therefore (b). The item is decided entirely on statement 1, and there is a clean elimination route for a candidate who cannot recall Yekaterinburg: the grouping originated as a Goldman Sachs investment thesis taken up politically by Russia, which convened the first foreign ministers' meeting and then the first summit, so the inaugural meeting on Russian soil is the natural expectation and Rio is the odd suggestion.

• Statement 3 alone is correct. Smallpox is the only human disease ever to have been eradicated. The last naturally occurring case in India was recorded in 1975, India was certified free of smallpox in 1977, and global eradication was certified by the World Health Organization in 1980 following the intensified programme built on surveillance, containment and ring vaccination.
• Statement 1 is incorrect. Diphtheria has been greatly reduced by DPT immunisation but continues to occur in India, with recurrent outbreaks in under-immunised populations; controlled is not eradicated.
• Statement 2 is incorrect. Chickenpox, caused by varicella zoster virus, remains endemic; varicella vaccine is not part of India's Universal Immunisation Programme, and because the virus establishes lifelong latency in dorsal root ganglia and reactivates as herpes zoster, it has a reservoir that makes eradication far harder than for smallpox. The official answer is (b). The governing distinction is between eradication, meaning permanent reduction of worldwide incidence to zero so that intervention can cease, elimination, meaning reduction to zero in a defined geographical area, and control. Smallpox was uniquely eradicable because it had no animal reservoir, no latent or carrier state, and a visible rash that made every case detectable.

• Statement 1 is correct. Dams and barrages fragment the river into isolated stretches, block the seasonal movements on which the species depends, and alter the flow and depth regime; the Farakka barrage is the standard Indian example, having divided the Ganges population and reduced dry season flows downstream.
• Statement 2 is incorrect. Crocodilian populations in the Ganges system have declined rather than increased, the gharial being critically endangered, and in any case the gharial is a specialised fish eater that is not a significant predator of dolphins. This is the planted statement.
• Statement 3 is correct. Accidental capture in gillnets is among the largest direct sources of mortality; the animal is functionally blind, navigating by echolocation, and monofilament nylon nets return a poor acoustic signal, so entanglement is common.
• Statement 4 is correct. Agricultural runoff brings organochlorine and organophosphate residues and nutrient loads into the river; the dolphin is a long-lived apex predator and accumulates persistent lipophilic compounds through biomagnification, with effects on reproduction and immunity, while nutrient enrichment depletes dissolved oxygen. The official answer is (c). The elimination is clean and single-step: statement 2 is the only implausible item in the set, and (c) is the only option that omits it.

• Option (c) is correct. Two Boundary Commissions, one for Punjab and one for Bengal, were constituted in July 1947 under the chairmanship of Sir Cyril Radcliffe, each with two nominees of the Congress and two of the Muslim League, to demarcate the boundaries of the two Dominions on the basis of contiguous majority areas of Muslims and non-Muslims, while also taking into account other factors. Radcliffe, who had never been to India before and arrived on 8 July, submitted the awards on 12 August and they were published on 17 August 1947, two days after independence.
• Option (a) is incorrect. The minorities question was handled by the Advisory Committee on Minorities under the Constituent Assembly and, earlier, through the Communal Award of 1932 and the Cabinet Mission proposals.
• Option (b) is incorrect but is the sharpest distractor: the Indian Independence Act 1947 was itself the instrument that gave effect to independence and it provided for the appointment of the boundary commissions, so the Radcliffe exercise was made under that Act rather than being the means of giving it effect.
• Option (d) is incorrect. The disturbances in East Bengal, notably Noakhali in 1946, were not the subject of any Radcliffe inquiry. The name is the key to the item, since the Radcliffe Line remains the accepted name of the India-Pakistan boundary.

Both statements are correct, so the official answer is (c). Brominated flame retardants, principally the polybrominated diphenyl ethers, hexabromocyclododecane and tetrabromobisphenol A, are added to textiles, foams, plastics and electronic casings to raise the ignition threshold.

• Statement 1 is correct because the carbon-bromine bonds and the aromatic ether structure resist microbial and photolytic breakdown, giving these compounds long environmental half-lives; they have been detected in Arctic air, sediments and biota far from any source, which is the signature of persistence combined with long-range transport.
• Statement 2 is correct because they are strongly lipophilic and poorly metabolised, so they partition into fatty tissue and biomagnify up food chains; body burdens have been measured in human serum and breast milk, and the toxicological concern is endocrine disruption, particularly interference with thyroid hormone signalling because of the structural resemblance to thyroxine. The two properties named are simply persistence and bioaccumulation, two of the four screening criteria for a persistent organic pollutant, the others being potential for long-range transport and adverse effects. A candidate who recognises the question as a POP screening question can answer it without knowing anything specific about this chemical class.

All three are correct, so the official answer is (c). Hibernation is a state of controlled metabolic depression in which body temperature, heart rate and oxygen consumption fall far below normal, allowing an animal to survive a season when food is scarce and thermoregulation would be prohibitively expensive.

• Statement 1 is correct: temperate insectivorous bats are among the deepest hibernators known, with body temperature dropping to within a degree or two of ambient and heart rate falling from several hundred beats a minute to a handful.
• Statement 3 is correct: rodents furnish the classical laboratory models of hibernation, including the ground squirrels, marmots, hamsters and the dormouse, whose name records the habit.
• Statement 2 is correct as conventionally taught: bears den through the winter, cease feeding, urinating and defecating for months, and depress metabolic rate substantially. The elimination route is decisive and requires only one fact. Rodents are indisputable hibernators, and (c) is the only option that contains statement 3, so the item is settled without any need to adjudicate the harder question of bears.

• Option (b) is correct. The Committee on Estimates has thirty members, all drawn from the Lok Sabha, with no Rajya Sabha representation, and is the largest of the parliamentary committees. It examines the estimates included in the budget and suggests economies in expenditure, and is often described as a continuous economy committee.
• Option (a) is incorrect. The Public Accounts Committee has twenty two members, fifteen from the Lok Sabha and seven from the Rajya Sabha.
• Option (c) is incorrect. The Committee on Public Undertakings also has twenty two members, fifteen from the Lok Sabha and seven from the Rajya Sabha, its strength having been raised from fifteen to twenty two in 1974.
• Option (d) is incorrect. The Committee on Petitions has fifteen members in the Lok Sabha and ten in the Rajya Sabha. The governing point of comparison is that the three financial committees are the ones a candidate is expected to hold numerically, and the discriminator among them is that Estimates is exclusively a Lok Sabha committee of thirty while the other two are joint in composition at twenty two. A minister may not be elected to any of the three.

• Statements 1, 2 and 4 are correct and statement 3 is incorrect, so the official answer is (c). Volcanic action releases carbon dioxide from the deep carbon reservoir through degassing at volcanic vents and mid-ocean ridges, and is the principal geological source that closes the long-term carbonate-silicate cycle. Respiration, whether in plants, animals or micro-organisms, oxidises organic carbon to carbon dioxide to release the energy stored in chemical bonds, and is a source by definition. Decay of organic matter is decomposer respiration under another name, in which saprotrophic bacteria and fungi mineralise dead tissue and return its carbon to the atmosphere as carbon dioxide, or as methane where conditions are anaerobic. Photosynthesis is the sole sink among the four, fixing atmospheric carbon dioxide into carbohydrate using light energy, and is therefore the planted false item. The governing principle is the distinction between a source and a sink, and the item requires nothing beyond it.
• Statement 3 alone decides the answer, and (c) is the only option that omits photosynthesis while retaining the other three.

Only statement 2 is correct, so the official answer is (b). The Common Myna, Acridotheres tristis, is a familiar commensal of human and livestock landscapes and habitually forages on the ground among grazing cattle, taking grasshoppers and other insects flushed by their movement; the generic name itself means grasshopper hunter.

• Statement 1 is incorrect. The Painted Stork is a wetland wader that feeds by tactile probing, wading in shallow water with its partly open bill submerged and snapping shut on contact with prey. It is a bird of jheels, tanks and marshes, not of dry grazing land, and it does not follow cattle.
• Statement 3 is incorrect. The Black-necked Crane is a high-altitude species of the Tibetan plateau, breeding in Ladakh and wintering in the Bhutan valleys and parts of Arunachal Pradesh, found in marshy high-altitude wetlands and associated agricultural fields; it is neither a countryside bird of the Indian plains nor a cattle follower. The design of the item is that the classic cattle follower, the Cattle Egret, is deliberately absent from the options, so a candidate expecting it must instead reason from the feeding ecology of each bird offered. Recognising that the Painted Stork is a tactile wetland feeder and the Black-necked Crane a Himalayan wetland species leaves the Common Myna alone.

• Option (b) is correct. Both terms appear in early medieval land grant inscriptions as designations of village level authority. Mahattara, literally the greater or elder one, denotes the village elder or headman, and mahattaras appear collectively as the body of leading villagers with whom royal officers dealt when a grant was made. Pattakila is the Sanskritised form that survives in the modern patel and patil of western and central India, and denotes the headman charged with revenue collection and village administration.
• Option (a) is incorrect. Military officers carried titles such as senapati, baladhikrita, mahasandhivigrahika for war and peace, and dandanayaka.
• Option (c) is incorrect. Specialists in Vedic ritual were the ritvij, purohita, hotri, adhvaryu and udgatri.
• Option (d) is incorrect. Guild heads were the shreshthi or jyeshthaka, and the guild itself the shreni or nigama. The item has no elimination route: all four options are plausible categories of medieval designation and nothing in either term is transparent to a candidate who has not met it in the epigraphic vocabulary. The one available handle is the derivation of pattakila into patel, which is a village headman title still in use, and a candidate who makes that connection can answer with confidence.

• Option (b) is correct. A lichen is a mutualistic association between a fungal partner, the mycobiont, usually an ascomycete, and a photosynthetic partner, the photobiont, which is a green alga or a cyanobacterium or both. The fungus supplies the thallus structure, anchorage and protection from desiccation and ultraviolet radiation, and absorbs mineral nutrients; the photobiont supplies carbohydrate by photosynthesis.
• Options (a) and (c) are incorrect because neither omits nor supplies the correct pair, each dropping one of the two partners and substituting bacteria in its place.
• Option (d) is incorrect: mosses are bryophytes and are not lichen partners, although they commonly follow lichens in the same successional sequence, which is why the option is placed here. The ecological point in the stem is worth holding separately. Lichens are the pioneer community of a lithosere, the primary succession on bare rock, because they can survive extreme desiccation and secrete organic acids that chemically weather the rock surface. Their action, with their accumulated dead tissue, generates the first thin soil on which mosses and then herbs can establish.

• Statements 3 and 4 are correct and statements 1 and 2 are incorrect, so the official answer is (c). Kosala, with its capital at Sravasti and its king Prasenajit, was central to the Buddha's career: he passed the largest number of rain retreats at the Jetavana monastery there, given by the merchant Anathapindika, and he was born at Lumbini in the Sakya republic, which lay within the Kosalan sphere. Magadha, with Rajagriha as its capital under Bimbisara and then Ajatashatru, was the other principal field of his activity; the Bamboo Grove at Rajagriha was among the earliest monastic gifts, the enlightenment took place at Bodh Gaya in Magadhan territory, and the first council met at Rajagriha after the parinirvana.
• Statement 2 is incorrect and is the easiest to reject. Gandhara lay in the far north-west around Taxila and Pushkalavati, well outside the middle Gangetic plain that bounded the Buddha's travels; Buddhism reached it later, under Ashoka and then the Kushanas, and its celebrated Buddhist art belongs to the first centuries of the common era.
• Statement 1 is incorrect for the purposes of this key. Avanti, with its capital Ujjayini under Pradyota, lay in western Malwa outside the region the Buddha traversed, which extended broadly between Kosala, Kasi, Magadha, Vajji, Malla and Anga. The elimination route runs through Gandhara, whose rejection removes (a) and (b) and leaves the item to be decided on Avanti alone, between (c) and (d).

• Option (b) is correct. The Gond and the Korku are the tribal communities of the Satpura and Melghat belt of Madhya Pradesh, Maharashtra and Chhattisgarh with whom this month-long tree-planting observance is associated, saplings of fruit-bearing species being planted as an act of collective religious merit and then protected by the community.
• Option (a) is incorrect. The Bhutia and the Lepcha are Sikkim and Darjeeling communities; the Lepcha are the autochthonous people of Sikkim and their sacred landscape observances are directed at Khangchendzonga rather than at a planting campaign.
• Option (c) is incorrect. The Irula and the Toda are Nilgiri communities of Tamil Nadu, the Irula a particularly vulnerable tribal group known for snake catching and the Toda pastoralists with a buffalo-centred ritual life.
• Option (d) is incorrect. The Sahariya are a particularly vulnerable tribal group of Madhya Pradesh and Rajasthan and the Agariya are associated with traditional iron smelting in central India, and with salt panning in the Little Rann in the western usage of the name. There is no elimination route worth the name. All four are genuine tribal pairs and each is regionally coherent, so the candidate either holds this specific association or does not.

• Option (d) is correct. At the date of this paper, tax on the sale or purchase of goods within a State was a State subject under Entry 54 of the State List, and the levy, which most States had by then converted from a single-point sales tax into Value Added Tax, was both imposed and collected by the State Government, the proceeds forming part of the State's own tax revenue.
• Option (a) is incorrect, since the Union had no power to tax an intra-State sale of goods.
• Option (b) is incorrect and is the sharpest distractor because it describes a real arrangement applied to a different transaction: Central Sales Tax on inter-State sale is levied by Parliament under Entry 92A of the Union List but, by force of Article 269, is assigned to the States and collected by them. The examiner is testing whether the candidate confuses intra-State with inter-State sale.
• Option (c) is incorrect and describes an arrangement that does not exist for sales tax. The governing distinction is between the power to impose and the power to collect, which the Constitution separates in Articles 268 to 269A precisely so that questions of this shape can be asked.

• Option (b) is correct. Venture capital is long-term risk capital, usually taking the form of equity or of instruments convertible into equity, supplied to new and early-stage enterprises that have high growth potential but no track record, no collateral and therefore no access to conventional bank credit. The venture capitalist accepts a high probability of total loss in individual investments in exchange for a share of ownership and the possibility of very large returns on the few that succeed, and typically exits after several years through a trade sale or a public issue.
• Option (a) is incorrect: short-term capital supplied to industry is working capital, met through cash credit, overdraft or trade credit.
• Option (c) is incorrect: funds supplied when a firm is making losses are rescue, turnaround or distressed finance, an altogether different proposition from backing an untested but promising venture.
• Option (d) is incorrect: finance for replacement and renovation is modernisation or replacement capital, usually a term loan against existing assets. The discriminating features are the stage of the enterprise, new rather than established, and the nature of the instrument, ownership rather than debt.

• Option (d) is correct. The Twelfth Five Year Plan, covering 2012 to 2017, carried the title Faster, More Inclusive and Sustainable Growth, and set an average growth target that was revised down from nine per cent in the Approach Paper to eight per cent in the final Plan document. The item is designed as a discrimination among near-identical formulations, and the way in is to trace the lineage. The Tenth Plan was built around growth with equity, the Eleventh Plan was titled Towards Faster and More Inclusive Growth, and the Twelfth Plan retained the whole of that phrase and added sustainability to it in recognition of the environmental and energy constraints on growth.
• Options (a), (b) and (c) each drop or alter one of the three elements: (a) omits faster and substitutes poverty reduction, (b) omits faster, and (c) omits faster and narrows the objective to unemployment. Only (d) carries all three of faster, sustainable and more inclusive.

• Statements 1 and 3 are correct and statements 2 and 4 are incorrect, so the official answer is (c). The current account of the balance of payments records transactions in goods, services, primary income and secondary income, and is conventionally presented in India as the balance of trade in merchandise plus the balance of invisibles, the latter comprising services, investment income and current transfers such as private remittances.
• Statement 2 is incorrect: foreign assets are stocks rather than flows and changes in them are recorded in the capital and financial account, while the assets themselves appear in the international investment position, which is a balance sheet rather than a flow statement.
• Statement 4 is incorrect: Special Drawing Rights are a reserve asset created by the International Monetary Fund and allocations of them are recorded in the capital account and reflected in the reserve position. The governing principle is the distinction between current transactions, which alter national income in the period, and capital transactions, which alter the ownership of assets and liabilities. Once that distinction is applied, statements 2 and 4 are both plainly asset items and the item resolves without any recall of the precise Indian presentation.

• Option (a) is correct. Both are Reserve Bank of India terms. The Marginal Standing Facility, introduced in May 2011, allows scheduled commercial banks to borrow overnight from the Reserve Bank against government securities, including by dipping into the Statutory Liquidity Ratio holding up to a prescribed limit, at a rate set above the repo rate; the MSF rate forms the upper bound of the liquidity adjustment facility corridor, with the reverse repo or standing deposit rate at the lower bound. Net Demand and Time Liabilities is the aggregate of a bank's demand liabilities, such as current accounts and the demand portion of savings, and its time liabilities, such as fixed deposits, net of inter-bank items, and it is the base on which the Cash Reserve Ratio and the Statutory Liquidity Ratio are computed.
• Options (b), (c) and (d) are all unrelated, and the item is a straightforward domain identification of the type the Commission uses to reward a candidate who reads the financial press. The word rate in the first term and liabilities in the second are both sufficient signals on their own.

Both statements are correct, so the official answer is (c). The business correspondent model, permitted by the Reserve Bank of India from January 2006 and progressively widened as to who may be engaged, allows a bank to deliver banking services through a retail agent in places where opening a brick-and-mortar branch is not viable. The correspondent operates as an extension of the bank, typically with a handheld micro-ATM device authenticating the customer biometrically against the bank's records.

• Statement 1 is correct: disbursement of government benefits, wages under the rural employment guarantee, pensions and subsidies through the correspondent in the village is one of the central purposes of the model, and it is what made Direct Benefit Transfer operable in unbanked areas.
• Statement 2 is correct: acceptance of small value deposits and payment of small value withdrawals are among the activities expressly permitted to a correspondent, along with the identification of borrowers, collection of small value credit and sale of micro-insurance and pension products. The item has no trap in it; both statements describe the model as designed, and a candidate who has grasped that the correspondent is a branch substitute rather than a mere referral agent will accept both.

• Statement 1 is correct and is the primary purpose. By requiring a bank to immobilise a proportion of its net demand and time liabilities as a cash balance with the Reserve Bank under the Cash Reserve Ratio, and a further proportion in prescribed liquid assets under the Statutory Liquidity Ratio, the central bank directly limits the volume of loanable funds and therefore the credit multiplier, which is how the requirement operates as an instrument of monetary control.
• Statement 3 is incorrect. Restraining bank profits is not an object of the requirement. Reduced profitability is an incidental consequence of holding low-yielding or non-yielding assets, and objects and consequences are different things.
• Statement 4 is incorrect. The Cash Reserve Ratio is maintained as a balance with the Reserve Bank and vault cash does not count towards it, while the amount of till money a bank holds for daily operations is a matter of its own cash management. The key treats statement 2 as incorrect, on the reasoning that depositor protection in India is provided by deposit insurance through the Deposit Insurance and Credit Guarantee Corporation and by prudential capital and provisioning norms, and that the Statutory Liquidity Ratio securities are an asset of the bank rather than a fund earmarked for depositors. The official answer is therefore (a).
• Statement 3 is the only one that falls away easily, and rejecting it removes (c) and (d), after which the item is a straight choice between (a) and (b) turning wholly on statement 2.

• Option (d) is correct. The wave of protest began in Tunisia in December 2010 after the self-immolation of Mohamed Bouazizi, a street vendor in Sidi Bouzid, and within weeks forced President Zine El Abidine Ben Ali from office in January 2011. The Tunisian example then propagated across the region.
• Option (a) is incorrect but is the strongest distractor, because the Egyptian protests centred on Tahrir Square from January 2011 were by far the most visible episode internationally and ended in the resignation of Hosni Mubarak in February 2011; they followed Tunisia rather than preceded it.
• Option (b) is incorrect: Lebanon's Cedar Revolution belongs to 2005 and to a different sequence of events.
• Option (c) is incorrect: the Syrian protests began in Deraa in March 2011, several months into the wave, and escalated into a civil war. The chronology is the whole of the question, and the ordering of Tunisia, then Egypt, then Libya, Yemen, Bahrain and Syria is the sequence to hold.

• Statements 1, 3 and 5 are correct, so the official answer is (d). The Arctic Council, established by the Ottawa Declaration of 1996, has eight Member States, and membership is confined to States with territory above the Arctic Circle: Canada, Denmark by virtue of Greenland and the Faroe Islands, Finland, Iceland, Norway, the Russian Federation, Sweden and the United States by virtue of Alaska. Six organisations of Arctic indigenous peoples sit as Permanent Participants with full consultation rights, which is the Council's distinctive institutional feature.
• Statement 2 is incorrect and statement 4 is incorrect: Japan and the United Kingdom are both Observers, not Members, the United Kingdom being among the earliest observers and Japan having been admitted in May 2013 in the same tranche as India. The item is built on the deliberate confusion of Observer with Member. The governing test is territorial: a State is a Member only if it has territory in the Arctic. Applying it disposes of Japan and the United Kingdom at once, and since every option contains exactly three entries, rejecting statement 2 removes (a) and (b), and rejecting statement 4 removes (c), leaving (d) without any need to verify Denmark, Russia and the United States individually.

• Pair 1 is correctly matched. Chechnya is a republic within the Russian Federation, in the North Caucasus, and was the theatre of two wars with Moscow in the 1990s and early 2000s.
• Pair 2 is incorrectly matched. Darfur is the western region of Sudan, not of Mali, and was the site of the conflict from 2003 that led to the International Criminal Court proceedings against Omar al-Bashir and to the deployment of the joint African Union and United Nations mission. The distractor works because Mali was itself in the news at this time over the northern insurgency and the French intervention of 2013.
• Pair 3 is incorrectly matched. The Swat Valley is in the Khyber Pakhtunkhwa province of Pakistan, not in Iraq, and was under Tehrik-i-Taliban control before the Pakistani military operation of 2009; it is also where Malala Yousafzai was shot in 2012. The official answer is therefore (a). A candidate confident of any one of the three mismatches makes progress, and rejecting pair 3 alone removes (b), (c) and (d) together.

• Statement 1 is correct. Agni-IV is a surface-to-surface ballistic missile, launched from a road-mobile transporter erector launcher.
• Statement 2 is incorrect. Agni-IV is a two-stage missile using solid propellant in both stages. Only the earliest Indian systems used liquid propellant, the Prithvi series and the first stage of Agni-I in its original configuration, and the whole direction of the Agni programme has been towards all-solid motors precisely because solid propellant permits the missile to be stored fuelled, moved on a launcher and fired at short notice, whereas a liquid-fuelled missile must be fuelled before launch and is therefore vulnerable and slow to react.
• Statement 3 is incorrect. Agni-IV has a range of the order of three thousand five hundred to four thousand kilometres with a payload of about one tonne. A figure of seven thousand five hundred kilometres exceeds even Agni-V, which is in the five thousand kilometre class, and would place the missile in the full intercontinental category, which India had not demonstrated. The official answer is therefore (a).
• Statement 2 is the decisive one and settles the item on a single principle rather than on a recalled number: the strategic logic of a survivable land-based deterrent requires solid propellant, and a candidate who holds that principle rejects statement 2 without hesitation, which removes (b) and (d), and statement 1 is beyond argument, which removes nothing but confirms (a) once statement 3 is rejected on range.

• Statement 1 is incorrect on both of its limbs. Coalbed methane is adsorbed on the internal surfaces of the coal matrix and is released when reservoir pressure is lowered by dewatering; it is predominantly methane, typically above ninety per cent, but is not pure, carrying carbon dioxide, nitrogen and traces of heavier hydrocarbons. Shale gas is not a mixture of propane and butane. It is natural gas generated and retained within a fine-grained organic-rich source rock, and it too is predominantly methane, which is why it is produced into the same gas infrastructure. The examiner has attached a false composition to shale gas to see whether the candidate treats the two as chemically different resources when in fact they differ in the rock that holds the gas and the technique needed to release it, not in what the gas is.
• Statement 2 is incorrect. Shale gas resources had been identified in India well before this paper, the prospective basins being Cambay, Krishna-Godavari, Cauvery, Damodar Valley, Assam-Arakan, Vindhyan and Rajasthan, and ONGC had drilled an assessment well in the Damodar Valley in West Bengal in 2011. Both statements failing, the official answer is (d).
• Statement 1 carries the elimination on its own, since the description of shale gas as propane and butane only is chemically wrong on any account and its rejection removes (a) and (c), leaving statement 2 to decide between (b) and (d).

• Statement 1 is incorrect. The Changpa are nomadic and semi-nomadic pastoralists of the Changthang plateau in eastern Ladakh, a cold desert lying above four thousand metres and continuous with the Tibetan plateau, and not of Uttarakhand. The Uttarakhand pastoral communities are the Bhotiya, the Van Gujjar and the Gaddi of the adjoining hills.
• Statement 2 is correct. The Changpa rear the Changthangi goat, whose winter undercoat is the pashm that yields pashmina, the fineness of the fibre being a physiological response to extreme cold and high altitude, which is why the same breed does not produce comparable fibre when moved to warmer ground. They also rear yak and the Changthangi sheep.
• Statement 3 is correct. The Changpa are notified as a Scheduled Tribe. The official answer is therefore (b).
• Statement 1 is both the eliminating and the decisive statement, and rejecting it removes (a) and (d) at once; a candidate who then knows the pashmina association, which is the best-known fact about the community, reaches (b) over (c) without needing to verify the Scheduled Tribe listing.

• Option (b) is correct. Guar gum is a galactomannan polysaccharide obtained from the endosperm of the cluster bean seed. In water it hydrates to give very high viscosity at low concentration, and it is cross-linked with borate or metal ions to form the gel that carries proppant, usually sand, into the fractures opened by hydraulic fracturing, holding them apart after pressure is released; a breaker is then used to degrade the gel so that the gas can flow. The expansion of shale gas production in the United States accordingly generated an enormous derived demand for Indian guar, which is grown chiefly in Rajasthan, Haryana and Gujarat, and prices rose sharply in 2012.
• Option (a) is incorrect: the commercial product of the seed is the gum from the endosperm, not an oil, and biodegradable plastics are made from starch, polylactic acid and polyhydroxyalkanoates.
• Option (c) is incorrect: no antihistamine property of the leaf is the reason for the crop's new significance.
• Option (d) is incorrect: guar is not a biodiesel feedstock, that role in India belonging to jatropha, pongamia and used cooking oil. The stem itself supplies the route, since it says the recent significance is new and commercial, and only option (b) names an industrial demand that arose recently.

• Statement 1 is incorrect and is the whole of the question. Terrace cultivation is a soil conservation measure, not a cause of erosion. Cutting a slope into a series of level or gently backward-sloping steps reduces the effective slope length and gradient, which reduces the velocity and therefore the erosive energy of surface runoff, and allows water to infiltrate rather than concentrate. The confusion the examiner is inviting is with shifting cultivation, which does accelerate erosion by exposing bare soil on slopes after burning.
• Statement 2 is correct. Removal of forest cover exposes soil to direct raindrop impact, ends the interception and litter protection that dissipate that impact, removes root reinforcement of the soil mass and increases the proportion of rainfall that becomes overland flow. The official answer is (b), and the option set makes the item decidable on statement 1 alone: (b) is the only option that omits terrace cultivation, so a candidate who rejects statement 1 need never adjudicate statement 3.

• Option (c) is correct. Seasonal reversal of the prevailing wind direction is the defining property of the monsoon, and the word itself derives from the Arabic mausim, meaning season. The reversal arises from the seasonal migration of the thermal equator and the Inter-Tropical Convergence Zone, the differential heating of land and sea and, in the South Asian case, the crossing of the equator by the south-east trades and their deflection to the right by the Coriolis effect to become the south-west monsoon. In winter the pressure pattern reverses and the flow is offshore from the continental high.
• Option (a) is incorrect: the equatorial climate is characterised by convergence, convectional afternoon rainfall throughout the year, low pressure and light variable winds, and there is no seasonal reversal.
• Option (b) is incorrect: the Mediterranean climate arises from the seasonal shifting of pressure belts, giving westerly cyclonic rain in winter and offshore trade wind influence with drought in summer, which is a seasonal change of regime but not a reversal of wind direction in the monsoon sense.
• Option (d) fails once either of the first two is rejected. The item is decided by holding the word monsoon to its own meaning.

• Option (c) is correct. Panchayatana is a temple plan in which the principal shrine stands on a common raised platform with four subsidiary shrines at the four corners, making five in all, which is what the name records. The subsidiary shrines house deities affiliated to the main deity, and the arrangement is sometimes associated with the panchayatana form of worship of the five principal deities, Vishnu, Shiva, Devi, Surya and Ganesha, systematised in the Smarta tradition. The Dashavatara temple at Deogarh and the Brahmeshvara temple at Bhubaneswar are standard illustrations.
• Option (a) is incorrect and is the trap the item is built on, since the word invites the reading panchayat, an assembly of five; the question expressly frames itself in terms of cultural history, which is the signal that an architectural or religious sense is wanted.
• Option (b) is incorrect, though the association with the worship of five deities gives it a thread of plausibility; panchayatana names the form, not a sect.
• Option (d) is incorrect: the administrative designations of the period are of the kind seen at Q21 of this paper.

• Pair 1 is correctly matched. The Harike wetland in Punjab was formed by the construction of a barrage in 1953 at the confluence of the Beas and the Sutlej, and is a Ramsar site and an important waterfowl wintering ground.
• Pair 2 is incorrectly matched. Keoladeo Ghana National Park at Bharatpur is a man-made and man-managed wetland created in the eighteenth century by the ruler of Bharatpur as a duck shooting reserve, fed by the Gambhir and Banganga rivers through the Ajan Bund; it does not lie at any confluence, and the Banas joins the Chambal far to the south in Sawai Madhopur district.
• Pair 3 is incorrectly matched. Kolleru Lake in Andhra Pradesh is a shallow freshwater lake lying between the deltas of the Krishna and the Godavari, fed by the Budameru and the Tammileru and connected to the sea by the Upputeru; it is not a confluence of the Musi and the Krishna, those two rivers meeting near Wazirabad in Telangana. The official answer is (a).
• Pair 1 is the securely known one, so the practical route is to confirm it and then treat pairs 2 and 3 with suspicion, since both attach a river confluence to a wetland whose water source is well known to be something else.

• Pairs 3 and 4 are correctly matched and pairs 1 and 2 are not, so the official answer is (c). The Mahadeo Hills are part of the Satpura system in Madhya Pradesh, containing Pachmarhi and the highest point of the Satpura range at Dhupgarh, and are correctly placed in central India. The Mikir Hills, now more commonly the Karbi Anglong hills, are an outlier of the peninsular block lying south of the Brahmaputra in Assam, and are correctly placed in the north-east.
• Pair 1 is incorrectly matched: the Cardamom Hills are the southernmost section of the Western Ghats, spanning Kerala and Tamil Nadu, and belong to the western side of the peninsula, whereas the Coromandel Coast is the eastern seaboard south of the Krishna delta.
• Pair 2 is incorrectly matched and is the reverse error: the Kaimur Hills are the eastern extension of the Vindhyan range running through Bihar, Uttar Pradesh and Madhya Pradesh, entirely inland, whereas the Konkan is the western coastal strip between Daman and Goa. The item is efficiently solved because the two false pairs are false in the same way, each transposing an interior or western feature to the wrong coast, and rejecting either pair 1 or pair 2 leaves only options that must be tested against the remaining pair.

• Option (d) is correct. The Tenth Schedule was inserted by the Constitution (Fifty-second Amendment) Act, 1985 and sets out the grounds on which a member of Parliament or of a State legislature incurs disqualification for defection, namely voluntarily giving up membership of the party on whose ticket the member was elected, or voting or abstaining contrary to the party direction without prior permission and without subsequent condonation, together with separate provisions for nominated members and independents. The exemption for a split by one-third of a legislature party was removed by the Ninety-first Amendment in 2003, leaving only merger by two-thirds.
• Option (a) is incorrect: the Second Schedule deals with the emoluments, allowances and privileges of the President, Governors, Speakers, judges and the Comptroller and Auditor General.
• Option (b) is incorrect: the Fifth Schedule provides for the administration and control of Scheduled Areas and Scheduled Tribes outside the north-eastern States covered by the Sixth Schedule.
• Option (c) is incorrect: the Eighth Schedule lists the languages recognised by the Constitution, at present twenty-two. The mnemonic worth holding is the sequence from the Eighth to the Twelfth, languages, land reform laws, defection, panchayats and municipalities.

• Option (a) is correct, and the words together with traditional human life are the whole of the question. A biosphere reserve under the UNESCO Man and the Biosphere Programme is zoned into a core, which is legally protected and left undisturbed, a buffer, where research, education and non-destructive activity are permitted, and a transition or manipulation zone, where human settlements, agriculture and sustainable resource use continue. It is the only one of the four designations that is designed to reconcile conservation with the continued presence and livelihood of resident communities, and to treat traditional knowledge as an asset rather than an intrusion.
• Option (c) is incorrect: a national park under the Wild Life (Protection) Act, 1972 is the most strictly protected category, in which grazing and rights are extinguished.
• Option (d) is incorrect: a wildlife sanctuary permits certain regulated rights but its object is species and habitat protection rather than the maintenance of a human cultural landscape.
• Option (b) is incorrect and is out of category altogether, a botanical garden being a form of ex-situ conservation, maintaining plants outside their natural habitat, whereas the question is asking about in-situ conservation of a living landscape.

• Option (b) is correct. Turkey occupies Anatolia and eastern Thrace, with the Black Sea along its entire northern coast and the Mediterranean along its southern coast, the two being connected through Turkish territory by the Bosphorus, the Sea of Marmara and the Dardanelles, which is the strategic fact that gives the country its importance and is regulated by the Montreux Convention of 1936.
• Option (a) is incorrect. Turkey does not touch the Caspian, which is an enclosed basin bordered by Russia, Kazakhstan, Turkmenistan, Iran and Azerbaijan; Turkey is separated from it by Armenia, Georgia and Azerbaijani territory.
• Option (c) is incorrect. The Gulf of Suez lies at the northern end of the Red Sea and the land between it and the Mediterranean is Egypt, traversed by the Suez Canal.
• Option (d) is incorrect. The Gulf of Aqaba and the Dead Sea lie on either side of the Wadi Araba in the Levant, between Israel and Jordan. The item is decided by knowing where the Turkish Straits are, since the whole point of Turkey's position is that it controls the only passage between the Black Sea and the Mediterranean.

• Option (c) is correct. Proceeding from south to north the order is Jakarta, Singapore, Bangkok, Hanoi. Jakarta lies on the north-west coast of Java at about six degrees south, and is the only one of the four in the southern hemisphere. Singapore sits at the southern tip of the Malay Peninsula at about one degree north, almost on the equator. Bangkok lies at the head of the Gulf of Thailand at about fourteen degrees north. Hanoi lies in the Red River delta of northern Vietnam at about twenty-one degrees north, and is the northernmost.
• Options (a) and (d) both begin with Singapore, which cannot be right because Jakarta is further south than any of the others.
• Option (b) places Hanoi second, which cannot be right because Hanoi is the northernmost of the four. The reliable method is to anchor the sequence at both ends rather than to attempt the whole ordering at once: fixing Jakarta as the southernmost and Hanoi as the northernmost leaves only Singapore and Bangkok to be ordered between them, and Singapore's position on the equator settles that.

• Statement 1 is correct. The terrestrial biosphere is at present a net carbon sink, absorbing roughly a quarter of anthropogenic emissions, but that sink weakens and can reverse with warming, because soil and plant respiration respond more strongly to temperature than photosynthesis does, because drought and heat reduce productivity, and because thawing permafrost and increased fire and dieback release stored carbon. Beyond about three degrees the projections converge on the land becoming a net source, which is the classic positive feedback.
• Statement 2 is correct. Reef-building corals bleach when thermal stress causes them to expel their zooxanthellae, and widespread mortality is projected at warming well below three degrees, so at three degrees it follows a fortiori.
• Statement 3 is incorrect. The claim that all global wetlands will permanently disappear is an absolute that no projection supports; wetlands will be altered, and coastal wetlands squeezed by sea level rise, but a total and permanent global loss is not a scientific finding.
• Statement 4 is incorrect for the same reason: cereal yields are projected to fall in the tropics and low latitudes, but poleward shifts and carbon dioxide fertilisation mean that cultivation somewhere in the world is not in question. The official answer is (b). The governing principle is that statements 3 and 4 are both unqualified absolutes, and (b) is the only option omitting both, so the item is decidable without any command of the climate science.

• Option (b) is correct. Article 51, in Part IV, directs the State to endeavour to promote international peace and security, to maintain just and honourable relations between nations, to foster respect for international law and treaty obligations in the dealings of organised peoples with one another, and to encourage settlement of international disputes by arbitration. It is the sole Directive Principle concerned with external relations and was drawn from the Irish Constitution and the Declaration of Havana.
• Option (a) is incorrect: the Preamble speaks of justice, liberty, equality and fraternity and of the sovereign socialist secular democratic republic, but says nothing of international peace.
• Option (c) is incorrect: the Fundamental Duties in Article 51A, inserted by the Forty-second Amendment, include promoting harmony and the spirit of common brotherhood among all the people of India, which is domestic and is the intended confusion, the numbering of the two articles making the trap sharper.
• Option (d) is incorrect: the Ninth Schedule is a list of statutes given protection from challenge on Fundamental Rights grounds by Article 31B, and has nothing to do with foreign policy.

• Statements 1, 3 and 4 are correct and statement 2 is incorrect, so the official answer is (c). A watershed is a drainage unit, the area from which runoff drains to a common outlet, and watershed development works on that unit as a whole through a ridge-to-valley sequence of treatments.
• Statement 1 is correct: contour bunding, trenching, gully plugging and check dams reduce the velocity and concentration of overland flow and therefore the detachment and transport of soil.
• Statement 3 is correct: the same structures detain runoff and increase the time available for infiltration, which is exactly how percolation tanks and check dams recharge the water table, and this is often the most visible benefit in hard-rock areas.
• Statement 4 is correct: afforestation, closure to grazing and soil moisture improvement together allow natural vegetation to re-establish, and vegetative measures are an integral part of the treatment rather than an incidental effect.
• Statement 2 is incorrect and belongs to an entirely different proposal, the interlinking of rivers, which operates at the scale of river basins and involves inter-basin transfer through link canals; it has no connection with watershed treatment, which is local and works within a single small catchment. The item is decided on statement 2 alone, and (c) is the only option that omits it.

The official answer is (c). The reasoning that supports it is that the two bodies named in statements 2 and 5 have a formal role in the making of a Plan, whereas the others do not. The National Development Council, constituted in 1952 and comprising the Prime Minister, Union Ministers, Chief Ministers of all States and members of the Planning Commission, was the body that considered and approved the Five Year Plan before it was finalised, and it also reviewed Plan implementation. Parliament had the final say, since the Plan was placed before it and, more concretely, since Plan outlays could only be spent on appropriation by Parliament.

• Statement 1 is treated as incorrect on the ground that the Finance Commission is a body constituted under Article 280 to recommend the distribution of tax proceeds between the Union and the States and the principles governing grants-in-aid, and under the arrangement then in force it was concerned with the non-Plan revenue account, Plan transfers being the province of the Planning Commission.
• Statements 3 and 4 are treated as incorrect on the ground that the Ministries of Rural Development and Urban Development are implementing agencies for sectoral programmes rather than participants in the formulation of the Plan itself. Eliminating statements 3 and 4 removes (b) and (d), after which the item turns entirely on whether the Finance Commission counts, that is, on (a) against (c).

• Statements 1 and 2 are correct and statement 3 is incorrect, so the official answer is (c). The Cabinet Secretariat functions under the direct charge of the Prime Minister and is administered by the Cabinet Secretary, who is the senior-most civil servant and the ex-officio chairman of the Civil Services Board. Its business is the servicing of the Cabinet and of the Cabinet Committees: preparing and circulating the agenda and the papers for meetings, recording and circulating the decisions, and monitoring their implementation by the ministries concerned.
• Statement 3 is incorrect and identifies a function that belongs unambiguously to the Ministry of Finance, whose Department of Expenditure and Department of Economic Affairs handle the allocation of financial resources through the budget process; no secretariat allocates money to ministries. The governing distinction is between a coordinating secretariat, which services decision-making and follows up on it, and a resource-allocating department, which controls money, and the two are deliberately kept separate. Rejecting statement 3 removes (b) and (d), and statement 1 is beyond argument, which leaves (c) over (a).

• Statement 2 is correct and statement 1 is incorrect, so the official answer is (b). Constitutional government means limited government. The defining idea of constitutionalism is not merely that a State has a constitution, since an authoritarian State may have one, but that the constitution imposes effective and enforceable limits on the exercise of public power, so that authority is exercised within bounds set in advance and subject to review. In the Indian arrangement those limits take the form of justiciable Fundamental Rights enforceable through Articles 32 and 226, the distribution of legislative power between the Union and the States, judicial review, and the basic structure doctrine which limits even the amending power.
• Statement 1 inverts the relationship, and describes an ordering in which liberty is subordinated to the authority of the State; that describes a police State or an absolutist order rather than a constitutional one. The item is decided by holding to the single idea that a constitution is an instrument for restraining power, and both statements offered are exact mirror images so that a candidate who fixes the direction of the restraint cannot go wrong.

• Statements 1 and 3 are correct and statements 2 and 4 are incorrect, so the official answer is (b).
• Statement 1 is a discretionary power because a report under Article 356 that the government of the State cannot be carried on in accordance with the Constitution is by its nature a report on the Council of Ministers, and it would be absurd to require the Governor to make it on the advice of the very ministry whose functioning is in question.
• Statement 3 is a discretionary power under Article 200, which expressly permits the Governor to reserve a bill for the consideration of the President, and the second proviso makes reservation obligatory where the bill would derogate from the powers of the High Court.
• Statement 2 is incorrect: Article 164 provides that the other Ministers shall be appointed by the Governor on the advice of the Chief Minister, so the Governor acts on advice, the only genuine element of discretion arising in the appointment of the Chief Minister himself in a hung assembly, which is not what the statement says.
• Statement 4 is incorrect: Article 166(3) empowers the Governor to make rules for the more convenient transaction of the business of the State Government, but that power, like the corresponding power of the President under Article 77(3), is exercised on ministerial advice, not in discretion. The governing test throughout is Article 163, under which the Governor acts on the aid and advice of the Council of Ministers except where required to act in his discretion, so a power is discretionary only where the Constitution says so or where the nature of the function makes advice impossible.

• Option (c) is correct. The interest rate is the cost of borrowed funds and the discount rate at which the future returns of a project are valued. A fall in it lowers the hurdle that a project must clear, so investments that were previously unviable become viable and the volume of planned investment expenditure rises; this is the investment demand schedule sloping downward against the rate of interest, and it is the principal channel through which monetary policy is transmitted to output.
• Option (a) is incorrect and is the wrong direction: cheaper credit raises interest-sensitive consumption, particularly of housing and consumer durables bought on credit, and it also reduces the reward for postponing consumption.
• Option (b) is incorrect: tax collection is not a direct function of the interest rate, and to the extent that lower rates raise activity and therefore the tax base, the effect is indirect, delayed and in the opposite direction to any presumption that a rate cut raises revenue on its own.
• Option (d) is incorrect and is the mirror of (a): a lower return on saving reduces the incentive to save, and the standard presentation has the saving schedule rising with the rate of interest. The item is settled by fixing the direction of a single relationship and then noticing that (a) and (d) both require the opposite direction.

• Statement 1 is correct and reproduces Article 77(3) almost verbatim; the rules so made are the Government of India (Allocation of Business) Rules and the Government of India (Transaction of Business) Rules, and although the article speaks of the President the power is exercised on the advice of the Council of Ministers.
• Statement 2 is incorrect. Article 77(1) provides that all executive action of the Government of India shall be expressed to be taken in the name of the President, not the Prime Minister, and Article 77(2) provides for authentication of orders and instruments so made, an authenticated instrument not being open to challenge on the ground that it was not made by the President. The substitution of the Prime Minister for the President is the whole of the trap. The underlying principle is that executive power of the Union is vested in the President by Article 53 and is exercised by him directly or through officers subordinate to him, the Prime Minister and the Council of Ministers being the real repository of decision but not the formal name in which action is taken. Rejecting statement 2 removes (b) and (c), and statement 1 being an accurate rendering of the text removes (d).

Both statements are correct, so the official answer is (c).

• Statement 1 is correct as a matter of text. The Constitution nowhere uses the expression no-confidence motion; what it provides, in Article 75(3), is that the Council of Ministers shall be collectively responsible to the House of the People, and the motion is the procedural device by which that responsibility is enforced. The device itself is a creature of Rule 198 of the Rules of Procedure and Conduct of Business in the Lok Sabha, which requires the support of at least fifty members for leave to move it.
• Statement 2 is correct and follows directly from Article 75(3), since responsibility runs to the House of the People alone. The Rajya Sabha cannot unseat a government; it may pass a motion of censure or disapproval against ministers or against the government's policy, but a motion of no-confidence in the Council of Ministers lies only in the Lok Sabha, which is why a Prime Minister who sits in the Rajya Sabha is nonetheless answerable through the lower House. The distinction to hold is between the constitutional principle of collective responsibility, which is in the text, and the parliamentary procedure for enforcing it, which is not.

• Statement 1 is correct. Neem oil and neem seed kernel extract contain azadirachtin and related limonoids, which act as antifeedants, oviposition deterrents and insect growth regulators, disrupting moulting by interfering with ecdysteroid function; they are effective against a wide range of chewing and sucking insects and against mites, and the mode of action makes resistance slow to develop.
• Statement 3 is correct. Neem oil and its fractions are used in antiseptic, antifungal and dermatological preparations, and nimbidin and related compounds are the subject of a large pharmacological literature. The key treats statement 2 as incorrect and answers (c). The rejection has to rest on the statement being compound: it asserts both biofuel manufacture and hospital detergent manufacture, and if either limb fails the whole fails. On the key's reading, neem seed oil as a biodiesel feedstock is a laboratory and pilot proposition rather than a manufacturing reality, and hospital detergent is not a recognised neem product line.
• Statements 1 and 3 are both secure, so eliminating either is impossible; the item is decided wholly on statement 2, between (c) and (d), with (a) and (b) removed by the security of statements 3 and 1 respectively.

• Option (b) is correct on the reading the examiner intends. Photosynthesis takes radiant energy, which is available and unstored, and converts it into chemical energy locked in the bonds of carbohydrate, where it remains stored until released by respiration. The light reactions in the thylakoid membrane use photon energy to drive water oxidation and electron transport, generating ATP and NADPH, and the carbon fixation reactions in the stroma use those to reduce carbon dioxide to triose phosphate. The direction of energy flow is from an available form to a stored form, which is what the option asserts.
• Option (a) is incorrect because it reverses that direction and describes the release of stored energy, which is respiration.
• Option (c) is incorrect and describes aerobic respiration precisely, the oxidation of food to carbon dioxide and water.
• Option (d) is incorrect and describes the gas exchange of respiration, whereas photosynthesis takes in carbon dioxide and releases oxygen; a candidate who fixes the gas exchange of the two processes disposes of (c) and (d) together. The item then reduces to (a) against (b) and is settled by the direction of energy conversion.

All three are correct, so the official answer is (d). A biometric modality is usable for identification if the underlying trait is sufficiently distinctive between individuals, sufficiently stable over time, universally present and practically measurable.

• Statement 1 is correct: the iris has a highly complex trabecular texture fixed in the first years of life and different even between the two eyes of one person and between identical twins, and iris recognition is among the most accurate modalities in use, which is why Aadhaar captures it.
• Statement 2 is correct: retinal scanning maps the pattern of blood vessels at the back of the eye, is extremely accurate, but requires close and cooperative presentation, so it is used in high-security applications rather than in mass enrolment; it is distinct from iris scanning, and the item is testing whether the candidate treats the two as the same thing.
• Statement 3 is correct: voice recognition uses vocal tract and behavioural characteristics and is a recognised modality, weaker than the ocular ones because voice varies with health, age and emotional state, but it is nonetheless in use, notably in telephone banking. The item asks what can be used, not what is most accurate, so the lower reliability of voice does not exclude it.

• Statements 1 and 3 are correct and statement 2 is incorrect, so the official answer is (c).
• Statement 1 is correct by definition: vegetative propagation proceeds by mitosis from somatic tissue of a single parent, so the progeny are genetically identical to the parent and to one another, which is what a clone is, and this is precisely why it is used for fruit crops where a desirable genotype must be preserved unchanged.
• Statement 3 is correct: because propagation does not depend on flowering, pollination or seed set, it is not confined to a reproductive season, and cuttings, layering, budding and grafting can be carried out over much of the year subject only to the physiological condition of the stock and scion.
• Statement 2 is incorrect and is the pivot of the item. Vegetative propagation perpetuates viruses rather than eliminating them, because most plant viruses are systemic and move through the vascular system, so any cutting, tuber, sucker or scion taken from an infected plant carries the infection with it; this is why virus accumulation over successive vegetative generations is a standing problem in potato, sugarcane, banana and citrus. The technique that does eliminate virus is meristem tip culture, and the reason it works is instructive: the apical meristem has no differentiated vascular tissue, its cells divide rapidly and outpace viral movement, and a sufficiently small excised tip is therefore usually virus-free.

• Pair 1 is incorrectly matched. Cassini-Huygens was a joint NASA, European Space Agency and Italian Space Agency mission to Saturn, not Venus; the Cassini orbiter entered Saturn orbit in 2004 and the Huygens probe descended to the surface of Titan in January 2005, the first landing in the outer solar system. Cassini did make two gravity-assist flybys of Venus on the way out, which is presumably where the distractor comes from, but a flyby en route is not the purpose of a mission.
• Pair 2 is correctly matched. MESSENGER, standing for Mercury Surface, Space Environment, Geochemistry and Ranging, entered Mercury orbit in March 2011 and mapped the planet in full, its most reported finding being water ice in permanently shadowed polar craters.
• Pair 3 is correctly matched. Voyager 1 and 2 were launched in 1977 and conducted the grand tour of the outer planets, Voyager 2 remaining the only spacecraft to have visited Uranus and Neptune. The official answer is (b).
• Pair 1 is the decisive one and Cassini's association with Saturn and Titan is secure enough that rejecting it removes (a), (c) and (d) in a single step.

All three pairs are incorrectly matched, so the official answer is (d).

• Pair 1 is wrong on climate. Kinnaur is a cold, high-altitude district of Himachal Pradesh in the trans-Himalayan rain shadow, known for apples, almonds, apricots and the chilgoza pine nut. Areca nut is a humid tropical palm crop, grown in Karnataka, Kerala, Assam and the coastal belt, and cannot be grown at that altitude.
• Pair 2 is wrong on region. Mewat, now Nuh, is a semi-arid district of southern Haryana on the Aravalli fringe, characterised by low rainfall, groundwater problems and pearl millet and mustard cultivation; the mango belts of northern India are in Uttar Pradesh around Malihabad, in Bihar and in Andhra Pradesh.
• Pair 3 is wrong on both region and crop ecology. The Coromandel is the eastern coastal plain south of the Krishna delta, given to rice, groundnut and coconut; soya bean is overwhelmingly a crop of the Malwa plateau of Madhya Pradesh and of Maharashtra and Rajasthan, grown on black soils in the kharif season. The governing principle is climatic matching rather than recall of any list, since each pair puts a crop in a climate that cannot support it.

• Statement 3 alone is correct, so the official answer is (b). The test for a chemical change is whether new substances with different chemical identities are formed, which requires the breaking and making of chemical bonds, and whether the change is readily reversible by physical means.
• Statement 1 is a physical change: crystallisation of sodium chloride from solution rearranges ions from the dissolved state into a lattice, but the substance remains sodium chloride throughout and dissolving the crystals restores the solution.
• Statement 2 is a physical change: melting of ice is a phase transition in which hydrogen bonds between water molecules are disrupted but no covalent bond within a water molecule is broken, so the substance is water before and after and freezing reverses it.
• Statement 3 is a chemical change: souring occurs because lactic acid bacteria ferment lactose to lactic acid, a different compound with different properties, and the fall in pH denatures casein and curdles the milk. Nothing can restore the original milk. The item is answered by applying the single criterion of whether a new substance is produced, and it is worth noting that the enthalpy involved in a phase change is comparatively small precisely because intermolecular rather than intramolecular forces are being overcome.

• Option (c) is correct. Article 131 confers on the Supreme Court exclusive original jurisdiction in any dispute between the Government of India and one or more States, between the Government of India and any State on one side and one or more other States on the other, or between two or more States, provided the dispute involves a question on which the existence or extent of a legal right depends. Exclusive means that no other court may entertain such a dispute, and original means that it comes to the Supreme Court at first instance rather than on appeal.
• Option (a) is incorrect: advisory jurisdiction arises under Article 143, where the President refers a question of law or fact of public importance for the Court's opinion, which is not binding.
• Option (b) is incorrect: appellate jurisdiction under Articles 132 to 134 and 136 requires a decision of a High Court or tribunal to appeal from, and a federal dispute has no such prior decision.
• Option (d) is incorrect and is the sharpest distractor because writ jurisdiction under Article 32 is also original, but it is confined to the enforcement of Fundamental Rights, which a State as such cannot claim. The discriminator between (c) and (d) is therefore the subject matter, federal dispute against Fundamental Rights, not the stage at which the Court is approached.

A transgenic crop is one into which a gene from outside the sexually compatible gene pool has been introduced, so the test for each item is whether it is a route by which foreign DNA is put into and expressed in a plant.

• Statement 1 is incorrect. Budding and grafting join the tissues of two plants so that they grow as one, but the scion and the stock retain their own genomes and no genetic material is transferred or recombined; it is a horticultural propagation technique of great antiquity and has nothing to do with transformation.
• Statement 3 is correct. Gene silencing, whether by antisense RNA or by RNA interference through the introduction of a construct producing double-stranded RNA, is achieved by inserting an engineered construct into the plant genome, so the resulting plant is transgenic; the delayed-ripening tomato and virus-resistant papaya are the standard examples, and RNA interference constructs against insect target genes are a current line of work.
• Statement 2 is treated as correct by the key. In its classical form cytoplasmic male sterility is a naturally occurring mitochondrial trait used in conventional hybrid seed production and involves no transgene at all, so the key must rest on the engineered male sterility systems, of which the barnase and barstar system is the leading example, where a ribonuclease gene under a tapetum-specific promoter is inserted to abolish pollen production and a matching inhibitor gene restores fertility in the hybrid. The official answer is (b).
• Statement 1 is the only one that can be rejected without hesitation, and doing so removes (a) and (c), after which the item turns on statement 2 between (b) and (d).

All three are correct, so the official answer is (d).

• Statement 1 is correct and is the largest industrial use of the grain: the maize kernel is roughly seventy per cent starch by weight, and wet milling separates it into starch, germ, gluten and fibre, the starch going on to modified starches, dextrose, high fructose syrup and a large range of food and industrial products.
• Statement 2 is correct: maize germ, separated in milling, yields corn oil, and any triglyceride oil can be transesterified with a short-chain alcohol to give fatty acid methyl esters, which is biodiesel. Whether it is economic to use an edible oil for the purpose is a separate question from whether it is technically a feedstock, and the statement claims only the latter.
• Statement 3 is correct: the starch is hydrolysed to fermentable sugars and fermented by yeast, which is the basis both of maize-based spirits such as bourbon and of fuel ethanol, the two differing in purification rather than in the underlying process. The item is answered by recognising maize as a starch crop and then reasoning that a starch crop with an oil-bearing germ necessarily supports all three uses, so no recall of an industrial list is needed.

• Option (b) is correct. Article 124(1) provides that there shall be a Supreme Court consisting of a Chief Justice of India and, until Parliament by law prescribes a larger number, of not more than seven other judges. The words until Parliament by law prescribes a larger number are the whole of the answer: the Constitution fixed a floor and left the strength to be increased by ordinary legislation, which Parliament has done repeatedly through the Supreme Court (Number of Judges) Act, 1956 and its amendments.
• Option (a) is incorrect and is the natural error, since the President appoints the judges under Article 124(2), but appointing individuals to sanctioned posts is different from creating the posts.
• Option (c) is incorrect: the Chief Justice is consulted in appointments and, since the Second Judges case, the collegium's recommendation is determinative in practice, but the Chief Justice cannot enlarge the sanctioned strength; the Chief Justice's role here is to press for an increase, not to effect one.
• Option (d) is incorrect: the Law Commission is a non-statutory advisory body that can recommend but not enact. The governing distinction is between the power to create a post by law and the power to fill it by appointment.

All three pairs are incorrectly matched, so the official answer is (d).

• Pair 1 is wrong: under the numbering then in force, National Highway 4 ran from Thane near Mumbai through Pune, Satara, Belgaum and Bangalore to Chennai, and did not touch Hyderabad at all; the Chennai to Hyderabad axis was carried by other highways.
• Pair 2 is wrong: National Highway 6 ran from Hazira in Gujarat through Dhule, Nagpur, Raipur and Sambalpur to Kolkata, so although it terminates at Kolkata it does not begin at Mumbai, and its western terminus is on the Gujarat coast.
• Pair 3 is wrong: National Highway 15 was the western border highway, running from Pathankot through Amritsar, Bathinda, Bikaner, Jaisalmer and Barmer to Samakhiali in Gujarat, a route designed for strategic access along the frontier rather than a link between Ahmedabad and Jodhpur. The item is genuinely difficult and offers no principled elimination route, since each pair names a plausible pair of cities and requires the candidate to have the route of a specific numbered highway in memory.
• Pair 2 is the one most often accepted wrongly, because Mumbai and Kolkata are the natural termini a candidate would expect of an east-west trunk route.

All three bear on biodiversity, so the official answer is (d).

• Statement 1 is the most direct: the International Treaty on Plant Genetic Resources for Food and Agriculture, adopted in 2001 under the Food and Agriculture Organization and often called the Seed Treaty, is concerned with the conservation and sustainable use of agricultural biodiversity, and establishes the multilateral system of access and benefit sharing over the listed crops and forages together with the recognition of Farmers' Rights.
• Statement 2 is correct: the United Nations Convention to Combat Desertification addresses land degradation in arid, semi-arid and dry sub-humid areas, and since degradation of those lands means loss of vegetation cover, soil biota and the habitat of dryland species, its objectives are inseparable from biodiversity; the Convention is one of the three Rio conventions and its synergies with the Convention on Biological Diversity are formally recognised.
• Statement 3 is correct: the World Heritage Convention of 1972 protects natural as well as cultural heritage, and the criteria for natural inscription expressly include sites containing the most important and significant natural habitats for in-situ conservation of biological diversity, under which India's Kaziranga, Keoladeo, Manas, Sundarbans, Nanda Devi and Valley of Flowers and the Western Ghats are inscribed. The trap is the assumption that only the Convention on Biological Diversity bears on biodiversity; the question asks for a bearing, which is a wide test, and each of the three meets it.

• Statements 2 and 3 are correct and statement 1 is incorrect, so the official answer is (c). Earth Hour is an initiative of the World Wide Fund for Nature, not of the United Nations Environment Programme or UNESCO. It began in Sydney in 2007 and became a global observance, held on a Saturday towards the end of March, in which individuals, businesses and civic authorities switch off non-essential lighting for one hour, landmark buildings being darkened as the visible expression of it.
• Statements 2 and 3 accurately describe the mechanism and the purpose respectively: the switching off is symbolic, the measurable saving in electricity over one hour being trivial, and the object is to build public awareness of climate change and to demonstrate the scale of public concern. The item is decided entirely on statement 1, and the elimination is clean, since rejecting it removes (a) and (d) and statements 2 and 3 are both unobjectionable. The general principle worth carrying is that a large proportion of the best-known global environmental observances are run by non-governmental bodies rather than by United Nations agencies, and candidates routinely over-attribute them to the United Nations.

• Option (a) is correct. A food chain runs from producer to primary consumer to secondary consumer, energy flowing in one direction and diminishing at each transfer. Diatoms are unicellular photosynthetic algae with silica frustules and constitute a large part of marine phytoplankton, so they are the producers and must come first. Crustaceans in this context are the zooplankton, principally copepods and krill, which graze on phytoplankton and are therefore primary consumers. Herrings are small pelagic fish that feed on zooplankton and are the secondary consumers, occupying the third trophic level.
• Options (b), (c) and (d) are all excluded by the single requirement that the producer must be at the base: (b) and (d) place crustaceans first, which would require an animal to be the producer, and (c) places herrings before crustaceans, which inverts predator and prey. The chain described is the classic short marine chain, and its shortness matters, since only about ten per cent of energy passes to the next level and marine chains with few links therefore support large fish populations.

• Option (b) is correct. The partition took effect on 16 October 1905 and was annulled by royal proclamation at the Delhi Durbar of December 1911, the announcement being made by King George V in person. The annulment was accompanied by two further changes: Bengal was reorganised on linguistic lines with Bihar and Orissa separated into a new province, and the capital was transferred from Calcutta to Delhi, a move calculated both to remove the government from the centre of nationalist agitation and to associate British rule with the imperial traditions of Delhi.
• Option (a) is incorrect: the First World War began in 1914, after the annulment.
• Option (c) is incorrect: the Civil Disobedience Movement began in 1930, nearly two decades later.
• Option (d) is incorrect and is the strongest distractor, since Bengal was in fact partitioned again in 1947 and East Bengal did become East Pakistan; the trap is to conflate the two partitions, which were separate events with different causes twenty-six years apart. The chronological anchor to hold is that the Delhi Durbar of 1911 carries three facts at once, the annulment, the reorganisation and the transfer of the capital.

• Option (b) is correct. The Lahore session of December 1929, held on the banks of the Ravi and presided over by Jawaharlal Nehru, adopted the resolution declaring Purna Swaraj, complete independence, as the goal of the Congress, in place of the dominion status that had been the working objective. The session authorised a programme of civil disobedience and directed that 26 January 1930 be observed as Independence Day, which is the reason that date was later chosen for the commencement of the Constitution.
• Option (a) is incorrect: self-government or swaraj within the empire was declared the Congress goal at the Calcutta session of 1906 under Dadabhai Naoroji.
• Option (c) is incorrect: the Non-Cooperation Movement was approved at the Calcutta special session of September 1920 and confirmed at Nagpur in December 1920.
• Option (d) is incorrect: the Congress decided to participate in the second Round Table Conference at the Karachi session of March 1931, following the Gandhi-Irwin Pact. The item is a chronology test and is settled by holding the sequence Lahore 1929, Dandi and Civil Disobedience 1930, Gandhi-Irwin and Karachi 1931.

• Statements 1 and 2 are correct and statement 3 is incorrect, so the official answer is (b).
• Statement 1 is correct: Sattriya grew out of the ankiya nat, the one-act devotional play, and combines music, dance and dramatic narration, so it is a total theatre form rather than dance alone.
• Statement 2 is correct: it was created in the fifteenth and sixteenth centuries by Srimanta Sankaradeva as a medium of the Ekasarana Nama-dharma form of Vaishnavism, and has been preserved as a living tradition in the sattras, the Vaishnava monasteries of Assam, where it was performed by celibate monks, the bhokots; it was recognised as a classical dance form by the Sangeet Natak Akademi in 2000, the eighth to be so recognised.
• Statement 3 is incorrect and is the pivot. The musical basis of Sattriya is the borgeet, the devotional songs composed by Sankaradeva and his disciple Madhavadeva in Brajavali, set to their own ragas and to the talas played on the khol and cymbals. Tulsidas, Kabir and Mirabai belong to the northern Bhakti tradition and have no connection with the Assamese Vaishnava repertoire. The governing point is that Sattriya is the creation of one identifiable regional Bhakti movement with its own literature and music, which the statement replaces with unrelated northern saint-poets.

• Option (a) is correct. The Indian national calendar, adopted with effect from 22 March 1957, which was 1 Chaitra 1879 of the Saka era, was framed on the recommendations of the Calendar Reform Committee chaired by Meghnad Saha. Chaitra 1 is tied to the vernal equinox: in an ordinary year of 365 days it falls on 22 March, the day after the equinox of 21 March, and in a leap year Chaitra is given 31 days instead of 30 and begins on 21 March, so that the correspondence with the Gregorian date is preserved thereafter. The structure of the year is that Chaitra has 30 days in an ordinary year, the next five months of Vaisakha to Bhadra have 31 days each, and the remaining six months of Asvina to Phalguna have 30 days each, which gives 365.
• Options (b), (c) and (d) are simply other dates and carry no reasoning behind them. The item is straight recall with no elimination route available, but a candidate who knows that the calendar was deliberately anchored to the vernal equinox can reconstruct the answer, since only option (a) lies at an equinox at all.

• Pairs 1 and 3 are correctly matched and pair 2 is not, so the official answer is (c).
• Pair 1 is correct: Cave 26 at Ajanta, a chaitya hall of the Vakataka phase, carries on its left wall the great reclining Mahaparinirvana image of the Buddha, some seven metres long, with celestial beings rendered in the space above the figure and the grieving disciples below, the contrast between serene detachment above and human grief below being the point of the composition.
• Pair 3 is correct: the vast open-air relief at Mamallapuram, carved on two adjoining granite boulders under the Pallavas in the seventh century, is variously read as Arjuna's penance for the Pasupata weapon or as the descent of the Ganga, the natural cleft between the boulders serving as the course of the river.
• Pair 2 is incorrect: the celebrated Varaha panel showing the boar incarnation raising Bhudevi from the waters is at Udayagiri near Vidisha in Madhya Pradesh, a Gupta period rock-cut site of about the early fifth century, and is read as an allegory of Chandragupta II's conquests. Mount Abu is famous for something else entirely, the Dilwara Jain temples with their marble ceilings and pillars, which belong to the eleventh to thirteenth centuries and are architecture rather than narrative relief. The item is decided on pair 2, and rejecting it removes (a) and (d).

• Option (a) is correct. The Ghadar Party was founded in 1913 among Punjabi emigrants on the Pacific coast of North America, with Sohan Singh Bhakna as president and Lala Har Dayal as secretary, and its headquarters was the Yugantar Ashram in San Francisco, from which it published the paper Ghadar in Urdu, Punjabi and other languages. The word means revolt or mutiny, chosen in conscious reference to 1857. On the outbreak of the First World War the party called on Indians abroad to return and raise an armed rising, which was planned for February 1915 and betrayed, leading to the Lahore Conspiracy Case.
• Option (c) is incorrect but names a real body: the Berlin Committee, later the Indian Independence Committee, was formed in 1915 by Virendranath Chattopadhyaya and others under German patronage, and worked with the Ghadar movement without being it.
• Option (d) is incorrect and likewise names something real: the émigré Communist Party of India was formed at Tashkent in 1920 by M. N. Roy and others.
• Option (b) is incorrect: Singapore is associated with the 1915 mutiny of the 5th Light Infantry and later with the Indian National Army, not with the Ghadar. The item rewards a candidate who keeps the several overseas revolutionary centres distinct.

• Option (d) is correct. Kalaripayattu is a martial art of Kerala, practised in the kalari, a pit-like training ground, and organised in a graded progression from body conditioning and footwork, through wooden weapons, to metal weapons including the flexible urumi, and finally to unarmed combat and the pressure-point techniques associated with the marma tradition. It is closely linked to Ayurveda through its system of massage and bone-setting, and it survives as a living practice rather than as a reconstructed one.
• Option (c) is the strongest distractor and is worth separating carefully, because it describes something real in almost the right place: the dance-drama traditions of northern Malabar are Theyyam and, elsewhere in Kerala, Krishnanattam and Kathakali, and Kathakali in fact draws its body training and stances from Kalaripayattu, which is why the two are easily conflated.
• Option (a) is incorrect: the Shaiva devotional tradition of the south is that of the Nayanars, whose hymns form the Tevaram.
• Option (b) is incorrect: the bronze tradition of the region is Chola bronze casting by the lost wax method. The word payattu, meaning practice or exercise, is itself the clue that the answer concerns training rather than performance or worship.

• Pairs 1 and 3 are correctly matched and pair 2 is not, so the official answer is (c).
• Pair 1 is correct: Garba is the circular folk dance of Gujarat performed around a perforated earthen lamp-pot during Navaratri, the name deriving from garbha, the womb, and the form is distinct from though performed alongside the stick dance, Dandiya Raas.
• Pair 3 is correct: Yakshagana is the night-long dance-drama of coastal Karnataka, combining elaborate headgear and painted faces with sung narration by the bhagavata and stories drawn from the epics and puranas.
• Pair 2 is incorrect: Mohiniyattam is a classical dance of Kerala, a solo form in the lasya mode performed by women in off-white and gold costume with the swaying torso movement that gives it its character, and its name refers to Mohini, the enchantress form of Vishnu. The classical dance of Odisha is Odissi, distinguished by the tribhanga stance and the chowka position. The item is decided on pair 2 alone, and the association of Mohiniyattam with Kerala is among the most securely known facts in the Indian classical dance syllabus, so rejecting it removes (b) and (d) at once.

• Pairs 1 and 3 are correctly matched and pair 2 is not, so the official answer is (c).
• Pair 1 is correct: Tabo, founded in 996 by the great translator Rinchen Zangpo under the patronage of the Guge kingdom, stands in the Spiti valley of Himachal Pradesh, is built of mud brick rather than stone and is celebrated for its wall paintings and stucco images, which is why it is often called the Ajanta of the Himalaya.
• Pair 3 is correct: the Alchi complex on the bank of the Indus in Ladakh belongs to the same eleventh to twelfth century phase and preserves the finest surviving Kashmiri-influenced painting in the western Himalaya, having escaped later renovation because the site was superseded rather than rebuilt.
• Pair 2 is incorrect on location: Nako, with its group of early temples including the Lhotsava Lhakhang dedicated to the translator, lies in the Hangrang valley of Kinnaur district in Himachal Pradesh, not in the Zanskar valley, which is in Ladakh. The item is difficult because all three sites belong to a single cultural horizon, the western Himalayan Buddhist revival associated with Rinchen Zangpo, and are separated only by valley, so a candidate must hold the geography of Spiti, Kinnaur and Ladakh separately rather than relying on the shared style or period.

Both statements are incorrect, so the official answer is (d).

• Statement 1 is incorrect: the Bijak is the principal compilation of the verses of Kabir, made by the Kabirpanth and organised into the ramainis, the sabdas and the sakhis, and the word means a seed or an inventory, in the sense of a document pointing to hidden treasure. The compositions of Dadu Dayal, the sixteenth-century saint of Rajasthan who founded the Dadupanth, are collected as the Dadu Bani or Dadu Anubhav Vani.
• Statement 2 is incorrect: Pushti Marg, the path of grace, was propounded by Vallabhacharya in the early sixteenth century on the metaphysics of Shuddhadvaita, pure non-dualism, and centres on the devotion to Krishna as Shrinathji, the Nathdwara temple being its principal seat. Madhvacharya, of the thirteenth century, propounded Dvaita, thoroughgoing dualism, and the Brahma Sampradaya of Udupi. The item is a straightforward test of whether the candidate attaches texts and doctrines to the right teachers, and both statements are constructed by the same method, attaching a real text or doctrine to the wrong figure, so a candidate who catches the method after the first statement will treat the second with suspicion.

• Option (b) is correct. The Manganiyar are a hereditary community of professional musicians in the Thar desert districts of western Rajasthan, principally Jaisalmer and Barmer, and across the border in Sindh. They are Muslim by faith but perform for Hindu and Muslim patrons alike and their repertoire draws on both traditions, the patronage system of jajmani binding particular musician families to particular patron families across generations. Their characteristic instrument is the bowed kamaycha, with the dholak and khartal, and they are often paired in discussion with the Langas, the other hereditary musician community of the region, who use the sindhi sarangi and the algoza.
• Option (a) is incorrect: the martial traditions of the north-east are Thang Ta of Manipur and the associated forms.
• Option (c) is incorrect: the Carnatic tradition is not associated with any single hereditary community of this kind.
• Option (d) is incorrect: pietra dura, the inlay of semi-precious stone in marble, is a Mughal decorative technique seen at the Taj Mahal and practised at Agra, and is a craft rather than a community's musical identity. The item rewards familiarity with the folk music map of Rajasthan.

• Statements 1 and 2 are correct and statement 3 is incorrect, so the official answer is (a). The Proclamation, read out by Lord Canning at Allahabad on 1 November 1858, gave public effect to the Government of India Act, 1858.
• Statement 2 is correct: the Act abolished the Court of Directors and the Board of Control, transferred the government of India to the Crown, and created the office of Secretary of State for India assisted by a Council of India, the Governor-General becoming also the Viceroy as the Crown's representative.
• Statement 1 is correct: the Proclamation renounced the desire for extension of territorial possessions and promised to respect the rights, dignity and honour of the Indian princes, which meant in substance the abandonment of the doctrine of lapse and the beginning of the policy of treating the princely states as subordinate allies rather than as candidates for annexation; it also promised religious non-interference, equal treatment in appointments and an amnesty for those not directly implicated in the killing of British subjects.
• Statement 3 is incorrect and is anachronistic by twenty-five years: the Company's commercial functions had already been ended by the Charter Act of 1833, which converted it into a purely administrative body, so by 1858 there was no Company trade left to regulate. Rejecting statement 3 removes (c) and (d).

• Option (c) is correct. The Ibadat Khana, the house of worship, was built at Fatehpur Sikri in 1575 and was the venue at which Akbar convened discussions on religion. Initially the debates were confined to Sunni ulama, but from 1578 they were opened to Shias, Sufis, Hindus, Jains, Zoroastrians and the Jesuit fathers from Goa, and it was the acrimony of the Sunni theologians among themselves, recorded with evident distaste by Badauni, that is generally credited with pushing Akbar towards the doctrine of sulh-i-kul, universal peace. The mahzar or so-called infallibility decree of 1579 and the Tauhid-i-Ilahi of 1582 followed from this trajectory, and the debates themselves were discontinued in 1582.
• Option (d) is the closest distractor and is wrong in two respects: the participants were scholars and divines rather than nobles, and Akbar presided rather than merely providing a room.
• Option (a) is incorrect: the congregational mosque at Fatehpur Sikri is the Jama Masjid, entered through the Buland Darwaza.
• Option (b) is incorrect: a private prayer chamber is a personal oratory and would defeat the entire purpose of a hall built for public disputation.

• Statement 3 alone is correct, so the official answer is (b). The Seed Replacement Rate is the proportion of the area under a crop sown with certified or quality seed rather than with farm-saved seed, and raising it raises yields because saved seed loses vigour and genetic purity over generations.
• Statement 1 is incorrect: the National Seeds Policy was notified in 2002, and the sector is additionally governed by the Seeds Act, 1966, the Seeds Control Order, 1983 and the Protection of Plant Varieties and Farmers' Rights Act, 2001.
• Statement 2 is incorrect and inverts the position: private participation in vegetable seed and horticultural planting material is not absent but dominant, because those crops are largely hybrid, the seed cannot be usefully saved, the value per unit of seed is high and the private breeder can therefore capture the return on investment.
• Statement 3 is correct, and the economics of it explain why the private sector cannot fill the gap. Low value, high volume crops such as wheat, paddy, coarse cereals and pulses are largely self-pollinated varietal crops, so a farmer can save seed and reuse it for several seasons, the seed multiplication ratio is low and bulk is high, which makes production, storage and transport costly relative to price. The private return is therefore poor and supply depends on public agencies, leaving a demand-supply gap. Rejecting statement 2, which is the easiest of the three, removes (a) and (c).

Both statements are incorrect, so the official answer is (d).

• Statement 1 is incorrect on the source of the power. Eco-Sensitive Zones are notified by the Central Government under section 3 of the Environment (Protection) Act, 1986, read with rule 5 of the Environment (Protection) Rules, 1986, which permit restrictions on industries, operations and processes in specified areas. The Wildlife (Protection) Act, 1972 is the statute under which national parks and sanctuaries themselves are declared, and the confusion is natural because an Eco-Sensitive Zone is notified around such a protected area; but the zone and the protected area are created under different statutes.
• Statement 2 is incorrect on the purpose and on the substance. The object is not prohibition but regulation: the zone functions as a shock absorber or transition belt around a protected area, so that the change from high protection to unregulated use is graded rather than abrupt. The notifications accordingly classify activities as prohibited, such as commercial mining, polluting industries and major hydroelectric projects, as regulated, such as felling of trees, establishment of hotels and widening of roads, and as permitted, which include ongoing agriculture and horticulture by local communities, rainwater harvesting and organic farming. Agriculture is thus one of several permitted activities, not the sole exception to a general prohibition.

• Statements 2 and 3 are correct and statement 1 is incorrect, so the official answer is (b).
• Statement 1 is incorrect: the Animal Welfare Board of India was established in 1962 under section 4 of the Prevention of Cruelty to Animals Act, 1960, which long predates the Environment (Protection) Act, 1986, and it is the statutory advisory body on animal welfare law.
• Statement 2 is correct: the National Tiger Conservation Authority was constituted in 2005 on the recommendation of the Tiger Task Force and given statutory status by the Wild Life (Protection) Amendment Act, 2006, which inserted Chapter IVB; it is chaired by the Minister in charge of Forests and Environment and it replaced the non-statutory Project Tiger directorate, the point of the change being to give the tiger conservation regime legal teeth.
• Statement 3 was correct when the paper was set: the National Ganga River Basin Authority was constituted in February 2009 under section 3(3) of the Environment (Protection) Act, 1986 as a planning, financing and monitoring authority for the Ganga basin, and was chaired by the Prime Minister. Rejecting statement 1 removes (a) and (d), after which the item turns on statement 3 between (b) and (c).

• Pairs 1 and 2 are correctly matched and pair 3 is not, so the official answer is (a).
• Pair 1 is correct: ascorbic acid is a cofactor for the hydroxylation of proline and lysine residues in procollagen, and without that hydroxylation the collagen triple helix is unstable, which is why deficiency produces the bleeding gums, poor wound healing, loose teeth and perifollicular haemorrhages of scurvy.
• Pair 2 is correct: vitamin D is required for the absorption of calcium from the gut and for normal mineralisation of the growing bone, and deficiency in children produces rickets, with bowing of the long bones and costochondral beading, the corresponding adult condition being osteomalacia.
• Pair 3 is incorrect: night blindness is the deficiency disease of vitamin A, because retinal, the aldehyde form of the vitamin, combines with opsin to form rhodopsin, the pigment of the rod cells that mediates vision in dim light, and its absence progresses through nyctalopia to xerophthalmia and keratomalacia. Vitamin E is an antioxidant tocopherol whose deficiency, uncommon in humans, presents with haemolysis and neurological signs. The item is decided on pair 3, and the vitamin A association with vision is among the most secure facts in the syllabus, so its rejection removes (b), (c) and (d) together.

All three are correct, so the official answer is (d). The properties that make engineered nanomaterials useful are the same properties that make them a concern, and all three statements follow from the very large surface area to volume ratio and the high surface reactivity that come with reducing particle size to the nanometre scale.

• Statement 1 is correct: metal and metal oxide nanoparticles, notably silver from antimicrobial textiles and titanium dioxide and zinc oxide from sunscreens and coatings, are released in use and in disposal, pass through conventional effluent treatment and partition into sludge, sediment and soil, where the elemental core does not degrade.
• Statement 2 is correct: uptake by micro-organisms, plants and invertebrates has been demonstrated, and trophic transfer up the chain has been shown experimentally, so entry into food chains is established rather than speculative.
• Statement 3 is correct and is the principal mechanism of nanotoxicity as currently understood: the abundance of surface defect sites and unsaturated coordination gives catalytic activity that generates reactive oxygen species, and the resulting oxidative stress damages lipids, proteins and DNA; photocatalytic titanium dioxide under ultraviolet light is the standard illustration. The unifying principle is that at the nanoscale the surface dominates the bulk, so behaviour cannot be predicted from the properties of the same element in ordinary particulate form.

• Option (a) is correct. The World Economic Outlook is the International Monetary Fund's flagship survey of the global economy, published twice a year in April and October with interim updates in January and July, containing the Fund's growth projections for the world and for individual member countries together with analytical chapters. It is one of a family of Fund publications that includes the Global Financial Stability Report and the Fiscal Monitor, and the three together cover the real economy, the financial system and the public finances.
• Option (b) is incorrect: the United Nations Development Programme publishes the Human Development Report, which carries the Human Development Index.
• Option (c) is incorrect: the World Economic Forum, a private foundation based in Geneva best known for the Davos meeting, publishes the Global Competitiveness Report, the Global Risks Report and the Global Gender Gap Report, and its similarity of name to the publication is exactly the trap.
• Option (d) is incorrect: the World Bank publishes the World Development Report and Global Economic Prospects, the latter being the closest competitor in subject matter and the one worth pairing with the World Economic Outlook in memory as the Bank's counterpart to the Fund's.
