Read the passage (Passage—6) — this item is based on it

The States are like pearls and the Centre is the thread which turns them into a necklace; if the thread snaps, the pearls are scattered.

Which one of the following views corroborates the above statement?

Answer & explanation

Answer: (b) A strong Centre is a binding force for national integrity.

The Centre is the thread that holds the States together as a necklace; if it snaps, they scatter. So a strong Centre is the binding force that keeps the nation integrated.

  • ✗ (a) The analogy says nothing about the States' strength; it stresses the Centre as the thread that binds.
  • ✓ (b) The thread (Centre) turns the pearls (States) into a necklace (the nation); without it they scatter — a strong Centre binds the nation.
  • ✗ (c) The statement does not present the Centre as an obstacle to the States.
  • ✗ (d) State autonomy is not the point of the analogy.

Remember · In analogy items, map each image to its meaning (thread = Centre, pearls = States) and choose the view that follows from that mapping.

Read the passage (Passage—7) — this item is based on it

Really I think that the poorest he that is in England has a life to live, as the greatest he, and therefore truly, I think it is clear that every man that is to live under a government ought first by his own consent to put himself under the government, and I do think that the poorest man in England is not at all bound in a strict sense to that government that he has not had a voice to put himself under.

The above statement argues for

Answer & explanation

Answer: (b) rule according to the consent of the governed

The speaker says every man, even the poorest, must first consent to a government before being bound by it, and is not bound by a government in which he had no voice. This argues for rule according to the consent of the governed.

  • ✗ (a) The rich and the poor are mentioned only to say that both have a life to live; sharing out wealth is not proposed.
  • ✓ (b) Every man 'ought first by his own consent to put himself under the government' — government must rest on the consent of the governed.
  • ✗ (c) The speaker wants the poorest to have a voice, not to rule over others.
  • ✗ (d) Taking property from the rich is not suggested anywhere.

Remember · Stay with the claim the speaker actually makes ('consent', 'voice'); options that go further, like rule of the poor, distort it.

Read the passage (Passage—1) — this item is based on it

Accountability, or the lack of it, in governance generally, and civil services, in particular, is a major factor underlying the deficiencies in governance and public administration. Designing an effective framework for accountability has been a key element of the reform agenda. A fundamental issue is whether civil services should be accountable to the political executive of the day or to society at large. In other words, how should internal and external accountability be reconciled? Internal accountability is sought to be achieved by internal performance monitoring, official supervision by bodies like the Central Vigilance Commission and Comptroller and Auditor General, and judicial review of executive decisions. Articles 311 and 312 of the Indian Constitution provide job security and safeguards to the civil services, especially the All India Services. The framers of the Constitution had envisaged that provision of these safeguards would result in a civil service that is not totally subservient to the political executive but will have the strength to function in larger public interest. The need to balance internal and external accountability is thus built into the Constitution. The issue is where to draw the line. Over the years, the emphasis seems to have tilted in favour of greater internal accountability of the civil services to the political leaders of the day who in turn are expected to be externally accountable to the society at large through the election process. This system for seeking accountability to society has not worked out, and has led to several adverse consequences for governance.

Some special measures can be considered for improving accountability in civil services. Provisions of articles 311 and 312 should be reviewed and laws and regulations framed to ensure external accountability of civil services. The proposed Civil Services Bill seeks to address some of these requirements. The respective roles of professional civil services and the political executive should be defined so that professional managerial functions and management of civil services are depoliticized. For this purpose, effective statutory civil service boards should be created at the centre and in the states. Decentralization and devolution of authority to bring government and decision making closer to the people also helps to enhance accountability.

According to the passage, which of the following factor/factors led to the adverse consequences for governance/public administration?

  1. 1.Inability of civil services to strike a balance between internal and external accountabilities
  2. 2.Lack of sufficient professional training to the officers of All India Services
  3. 3.Lack of proper service benefits in civil services
  4. 4.Lack of Constitutional provisions to define the respective roles of professional civil services vis-a-vis political executive in this context

Select the correct answer using the code given below:

Answer & explanation

Answer: (c) 1 and 4 only

The passage blames the tilt towards internal accountability to political leaders, a balance that was never properly struck, for the adverse consequences, and it asks that the respective roles of civil services and the political executive be defined. Training and service benefits are never mentioned.

  • ✓ 1. The emphasis 'tilted in favour of greater internal accountability', and this system 'has not worked out, and has led to several adverse consequences' — the balance was not struck.
  • ✗ 2. Professional training of officers is not discussed anywhere in the passage.
  • ✗ 3. Service benefits are not discussed; the job security under Articles 311 and 312 is never called inadequate.
  • ✓ 4. 'The issue is where to draw the line': the passage wants Articles 311 and 312 reviewed and the 'respective roles' of civil services and the political executive 'defined' — they are not defined now.

Remember · Accept only causes the passage ties to the problem; a remedy it proposes ('roles should be defined') points to a gap behind the problem.

With reference to the passage, the following assumptions have been made:

  1. 1.Political executive is an obstacle to the accountability of the civil services to the society
  2. 2.In the present framework of Indian polity, the political executive is no longer accountable to the society

Which of these assumptions is/are valid?

Answer & explanation

Answer: (a) 1 only

Civil servants have come to answer mainly to political leaders, and this route to accountability to society has failed; so the political executive stands between the civil services and society. But the passage never says politicians are no longer accountable — they are still meant to answer to society through elections.

  • ✓ 1. Accountability runs to 'the political leaders of the day'; this system 'has not worked out', and the passage wants civil service management 'depoliticized' — the political executive is treated as the obstacle.
  • ✗ 2. Too sweeping: political leaders are still 'expected to be externally accountable ... through the election process'; what failed is using that route for the civil services.

Remember · An assumption must be needed by the argument; reject statements that stretch a partial failure into 'no longer' or 'never'.

Which one of the following is the essential message implied by this passage?

Answer & explanation

Answer: (d) There is a need and scope for reforms to improve the accountability of civil services

The first paragraph sets out the accountability problem and the second lists 'special measures' — reviewing Articles 311 and 312, a Civil Services Bill, statutory boards and decentralization. The essential message is that reforms to improve civil service accountability are both needed and possible.

  • ✗ (a) Too sweeping: the passage says the balance tilted towards internal accountability, not that civil services answer to no one.
  • ✗ (b) The education or quality of political leaders is never discussed.
  • ✗ (c) The framers did foresee the issue: 'The need to balance internal and external accountability is thus built into the Constitution'.
  • ✓ (d) The second paragraph is a list of measures 'for improving accountability in civil services'.

Remember · The 'essential message' usually sits where the passage moves from problem to solution; pick the option that covers both.

Decentralization and devolution of authority to bring government and decision making closer to the people also helps to enhance accountability.

According to the passage, which one of the following is not a means of enhancing internal accountability of civil services?

Answer & explanation

Answer: (d) Seeking accountability through enhanced participation by people in decision making process

UPSC's official answer: (d) · the answer UPSC accepted, and the one that counts in the exam

Also defensible: (a)

  • The passage lists the internal means itself: internal accountability 'is sought to be achieved by internal performance monitoring, official supervision by bodies like the Central Vigilance Commission and Comptroller and Auditor General, and judicial review of executive decisions'. That covers (b) and (c); job security is not on the list.
  • Articles 311 and 312 are presented as safeguards so that the civil service 'is not totally subservient to the political executive', and the passage wants them 'reviewed' so that laws can 'ensure external accountability'. A shield against the political executive does not enhance accountability to it, so (a) is also not a means of internal accountability.
  • Option (d) sits squarely on the other side: decentralisation brings 'decision making closer to the people' and enhances accountability to society, which the passage calls external. That is why UPSC's key gives (d); strictly, (a) and (d) both fail the stem's test.

UPSC's key is (d), the one option the passage files under external accountability; (a) is also absent from the passage's own list of internal means. In the exam, when a passage sets up an internal/external contrast, mark the option the passage places on the other side.

This box is Minimalist IAS's analysis, with its sources; it does not change UPSC's answer.

The passage names the means of internal accountability — internal performance monitoring, supervision by bodies such as the CVC and CAG, and judicial review of executive decisions — and sets them against external accountability to society. Bringing decision making closer to the people enhances accountability to society, so (d) is the one option on the external side.

  • ✗ (a) Articles 311 and 312 give the service job security and safeguards within the constitutional framework of the executive; the passage uses them to show how internal and external accountability are balanced, not as a route by which the people hold the service to account.
  • ✗ (b) Named directly: 'official supervision by bodies like the Central Vigilance Commission'.
  • ✗ (c) Named directly: 'judicial review of executive decisions'.
  • ✓ (d) Decentralization that brings decision making 'closer to the people' builds accountability to society — the external kind that the passage contrasts with internal accountability.

Remember · In 'which is NOT' items, sort each option into the passage's own categories; the option that belongs to the other category is the answer.

Read the passage (Passage—2) — this item is based on it

In general, religious traditions stress our duty to god, or to some universal ethical principle. Our duties to one another derive from these. The religious concept of rights is primarily derived from our relationship to this divinity or principle and the implication it has on our other relationships. This correspondence between rights and duties is critical to any further understanding of justice. But, for justice to be practiced; virtue, rights and duties cannot remain formal abstractions. They must be grounded in a community (common unity) bound together by a sense of common union (communion). Even as a personal virtue, this solidarity is essential to the practice and understanding of justice.

With reference to the passage, the following assumptions have been made:

  1. 1.Human relationships are derived from their religious traditions
  2. 2.Human beings can be duty bound only if they believe in god
  3. 3.Religious traditions are essential to practice and understand justice

Which of these assumption(s) is/are valid?

Answer & explanation

Answer: (a) 1 only

The passage says our duties to one another derive from religious traditions' stress on duty to god or a universal principle, so assumption 1 holds. It allows 'some universal ethical principle' in place of god, and it calls community solidarity — not religion — essential to justice, so 2 and 3 fail.

  • ✓ 1. 'Our duties to one another derive from these', and the concept of rights shapes 'our other relationships' — relationships flow from religious traditions.
  • ✗ 2. 'Only if they believe in god' is too extreme; the duty may be to 'some universal ethical principle'.
  • ✗ 3. What is 'essential to the practice and understanding of justice' is solidarity in a community, not religious tradition.

Remember · Watch the qualifiers — 'only', 'essential', 'always'. An assumption carrying one must be backed by the passage's own words.

Even as a personal virtue, this solidarity is essential to the practice and understanding of justice.

Which one of the following is the crux of this passage?

Answer & explanation

Answer: (c) Balance between rights and duties is crucial to the delivery of justice in a society

The passage moves from religious duties and rights to its main point: the correspondence between rights and duties is critical to understanding justice, and justice must be practised in a community. So the crux is that balancing rights and duties is central to justice in a society.

  • ✗ (a) A supporting detail from the opening lines, not the point the passage builds to.
  • ✗ (b) The passage never calls the relationship to the divine a 'great virtue'.
  • ✓ (c) 'This correspondence between rights and duties is critical to any further understanding of justice', and justice must be grounded in a community.
  • ✗ (d) Another opening detail; the passage uses it only to reach the rights–duties link and justice.

Remember · The crux is the point the details lead to; an option that restates one early sentence is usually a supporting detail.

Read the passage (Passage—1) — this item is based on it

Biomass as fuel for power, heat, and transport has the highest mitigation potential of all renewable sources. It comes from agriculture and forest residues as well as from energy crops. The biggest challenge in using biomass residues is a long-term reliable supply delivered to the power plant at reasonable costs; the key problems are logistical constraints and the costs of fuel collection. Energy crops, if not managed properly, compete with food production and may have undesirable impacts on food prices. Biomass production is also sensitive to the physical impacts of a changing climate.

Projections of the future role of biomass are probably overestimated, given the limits to the sustainable biomass supply, unless breakthrough technologies substantially increase productivity. Climate-energy models project that biomass use could increase nearly four-fold to around 150 – 200 exajoules, almost a quarter of world primary energy in 2050. However the maximum sustainable technical potential of biomass resources (both residues and energy crops) without disruption of food and forest resources ranges from 80 – 170 exajoules a year by 2050, and only part of this is realistically and economically feasible. In addition, some climate models rely on biomass-based carbon capture and storage, an unproven technology, to achieve negative emissions and to buy some time during the first half of the century.

Some liquid biofuels such as corn-based ethanol, mainly for transport, may aggravate rather than ameliorate carbon emissions on a life-cycle basis. Second generation biofuels, based on ligno-cellulosic feedstocks – such as straw, bagasse, grass and wood – hold the promise of sustainable production that is high-yielding and emit low levels of greenhouse gases, but these are still in the R & D stage.

What is/are the present constraint/constraints in using biomass as fuel for power generation?

  1. 1.Lack of sustainable supply of biomass
  2. 2.Biomass production competes with food production
  3. 3.Bio-energy may not always be low carbon on a life-cycle basis

Select the correct answer using the code given below:

Answer & explanation

Answer: (d) 1, 2 and 3

The passage names all three: a reliable, sustainable supply of biomass is the biggest challenge; energy crops compete with food production; and some biofuels such as corn-based ethanol may worsen carbon emissions on a life-cycle basis.

  • ✓ 1. 'The biggest challenge ... is a long-term reliable supply', and projections ignore 'the limits to the sustainable biomass supply'.
  • ✓ 2. 'Energy crops, if not managed properly, compete with food production'.
  • ✓ 3. Corn-based ethanol 'may aggravate rather than ameliorate carbon emissions on a life-cycle basis'.

Remember · For 'constraints', collect every problem the passage states — supply, competing uses, side effects — before looking at the codes.

  2. 2.Using biomass for carbon capture and storage
  3. 3.Promoting the cultivation of energy crops

Select the correct answer using the code given below:

Answer & explanation

Answer: (b) 3 only

Only energy crops are said to compete with food production and to affect food prices. Residues are by-products of farms and forests, and carbon capture and storage is mentioned only as an unproven technology — neither is linked to food.

  • ✗ 1. For residues the passage worries about supply logistics and collection costs, not food.
  • ✗ 2. Carbon capture and storage is called 'an unproven technology'; no link to food is drawn.
  • ✓ 3. Energy crops 'compete with food production and may have undesirable impacts on food prices'.

Remember · Tie each statement to the exact sentence about it; a risk named for one source (energy crops) does not carry over to others.

In the context of using biomass, which of the following is/are the characteristic/characteristics of the sustainable production of biofuel?

  1. 1.Biomass as a fuel for power generation could meet all the primary energy requirements of the world by 2050
  2. 2.Biomass as a fuel for power generation does not necessarily disrupt food and forest resources
  3. 3.Biomass as a fuel for power generation could help in achieving negative emissions, given certain nascent technologies

Select the correct answer using the code given below:

Answer & explanation

Answer: (c) 2 and 3 only

The passage sets a sustainable potential of 80 – 170 exajoules a year obtainable without disrupting food and forest resources, and notes that nascent biomass-based carbon capture and storage could give negative emissions. But even the high projection is only about a quarter of world primary energy, not all of it.

  • ✗ 1. Even the high projection is 'almost a quarter of world primary energy in 2050'.
  • ✓ 2. There is a 'maximum sustainable technical potential ... without disruption of food and forest resources'.
  • ✓ 3. Some models rely on 'biomass-based carbon capture and storage, an unproven technology, to achieve negative emissions'.

Remember · Numbers in the passage are the test: 'almost a quarter' can never become 'all'.

  1. 1.Some climate-energy models suggest that the use of biomass as a fuel for power generation helps in mitigating greenhouse gas emissions
  2. 2.It is not possible to use biomass as a fuel for power generation without disrupting food and forest resources

Which of these assumptions is/are valid?

Answer & explanation

Biomass has 'the highest mitigation potential of all renewable sources', and climate-energy models project its use rising nearly four-fold — so these models treat it as cutting emissions. The passage also gives a potential available without disrupting food and forest resources, which rules out statement 2.

  • ✓ 1. 'Highest mitigation potential', a projected four-fold rise in use, and some models even rely on biomass for 'negative emissions'.
  • ✗ 2. The passage puts 80 – 170 exajoules a year within reach 'without disruption of food and forest resources'.

Remember · An assumption the passage directly contradicts is invalid, however plausible it sounds.

Read the passage (Passage—2) — this item is based on it

We are witnessing a dangerous dwindling of biodiversity in our food supply. The green revolution is a mixed blessing. Over time farmers have come to rely heavily on broadly adapted, high yield crops to the exclusion of varieties adapted to the local conditions. Monocropping vast fields with the same genetically uniform seeds helps boost yield and meet immediate hunger needs. Yet high-yield varieties are also genetically weaker crops that require expensive chemical fertilizers and toxic pesticides. In our focus on increasing the amount of food we produce today, we have accidentally put ourselves at risk for food shortages in future.

Which among the following is the most logical and critical inference that can be made from the above passage?

Answer & explanation

Answer: (d) Green revolution can pose a threat to biodiversity in food supply and food security in the long run

The passage calls the green revolution a mixed blessing: reliance on uniform high-yield crops has caused a 'dangerous dwindling of biodiversity' in our food and has put us 'at risk for food shortages in future'. So it can threaten both biodiversity and long-run food security.

  • ✗ (a) 'Only due to green revolution' is too extreme; the passage links chemicals to high-yield varieties, not as the sole cause of dependence.
  • ✗ (b) A plain factual link that leaves out the risk the passage is warning about.
  • ✗ (c) 'The only way' runs against the passage, which says this practice risks future food shortages.
  • ✓ (d) 'Dangerous dwindling of biodiversity in our food supply' and 'at risk for food shortages in future'.

Remember · A 'critical inference' carries the author's warning; drop options with 'only' and neutral facts that miss the author's concern.

Read the passage (Passage—1) — this item is based on it

By killing transparency and competition, crony capitalism is harmful to free enterprise, opportunity and economic growth. Crony capitalism, where rich and the influential are alleged to have received land and natural resources and various licences in return for payoffs to venal politicians, is now a major issue to be tackled. One of the greatest dangers to growth of developing economies like India is the middle-income trap where crony capitalism creates oligarchies that slow down the growth.

Which among the following is the most logical corollary to the above passage?

Answer & explanation

Answer: (c) Greater transparency in the functioning of the government and promoting the financial inclusion are needed at present

The passage blames crony capitalism — land, resources and licences traded for payoffs — for killing transparency and competition and for creating oligarchies that slow growth. The corollary is greater transparency in government, with financial inclusion widening opportunity beyond the favoured few.

  • ✗ (a) More welfare spending does nothing about cronyism, the problem the passage raises.
  • ✗ (b) 'Other means' of growth and licences for the poor sidestep the real issue — lost transparency and competition.
  • ✓ (c) Crony capitalism works 'by killing transparency and competition'; transparency and wider access to finance counter it.
  • ✗ (d) Manufacturing versus services is never discussed.

Remember · A corollary follows straight from the passage's diagnosis; choose the option that removes the cause the passage names.

Read the passage (Passage—2) — this item is based on it

Climate adaptation may be rendered ineffective if policies are not designed in the context of other development concerns. For instance, a comprehensive strategy that seeks to improve food security in the context of climate change may include a set of coordinated measures related to agricultural extension, crop diversification, integrated water and pest management and agricultural information services. Some of these measures may have to do with climate changes and others with economic development.

What is the most logical and rational inference that can be made from the above passage?

Answer & explanation

Answer: (d) Climate adaptation should be examined in tandem with other economic development options

The passage says adaptation may fail if policies ignore other development concerns, and its food security example mixes climate measures with economic development measures. So climate adaptation must be planned together with other development options.

  • ✗ (a) Developing countries are not singled out, and difficulty is not the point.
  • ✗ (b) The passage never compares how complex food security and adaptation are.
  • ✗ (c) 'Every developmental activity' is too sweeping; only 'some of these measures' concern climate.
  • ✓ (d) Adaptation 'may be rendered ineffective if policies are not designed in the context of other development concerns'.

Remember · The opening sentence often states the thesis and the example supports it; pick the option that restates the thesis.

Read the passage (Passage—3) — this item is based on it

Understanding of the role of biodiversity in the hydrological cycle enables better policy-making. The term biodiversity refers to the variety of plants, animals, microorganisms, and the ecosystems in which they occur. Water and biodiversity are interdependent. In reality, the hydrological cycle decides how biodiversity functions. In turn, vegetation and soil drive the movement of water. Every glass of water we drink has, at least in part, passed through fish, trees, bacteria, soil and other organisms. Passing through these ecosystems, it is cleansed and made fit for consumption. The supply of water is a critical service that the environment provides.

Which among the following is the most critical inference that can be made from the above passage?

Answer & explanation

Answer: (a) Biodiversity sustains the ability of nature to recycle water

Water and biodiversity are interdependent: vegetation and soil drive the movement of water, and water passing through fish, trees, bacteria and soil is cleansed. So biodiversity sustains nature's ability to cycle and renew water.

  • ✓ (a) 'Vegetation and soil drive the movement of water', and passing through ecosystems water 'is cleansed and made fit for consumption'.
  • ✗ (b) 'Cannot ... without' is too absolute; water passes through organisms only 'at least in part'.
  • ✗ (c) Generally true, but the passage is about water and biodiversity, not interaction among organisms.
  • ✗ (d) How life came into existence is outside the passage.

Remember · Reject absolute words ('cannot', 'never') when the passage hedges ('at least in part'); the right inference keeps the passage's own link.

In the last decade, the banking sector has been restructured with a high degree of automation and products that mainly serve middle-class and upper middle-class society. Today there is a need for a new agenda for the banking and non-banking financial services that does not exclude the common man.

Which one of the following is the message that is essentially implied in the above passage?

Answer & explanation

Answer: (d) Need to promote financial inclusion

Banking has been restructured to serve mainly the middle and upper-middle classes, and the passage calls for an agenda that 'does not exclude the common man'. Bringing excluded people into banking and finance is financial inclusion.

  • ✗ (a) More automation and products is what has already happened — for the better-off.
  • ✗ (b) The passage is about banking and non-banking financial services, not the whole public finance system.
  • ✗ (c) Merging the two kinds of institutions is not suggested.
  • ✓ (d) A new agenda 'that does not exclude the common man' is financial inclusion.

Remember · Name the idea the author describes without naming it — 'does not exclude the common man' means financial inclusion.

Read the passage (Passage—5) — this item is based on it

Safe and sustainable sanitation in slums has immeasurable benefits to women and girls in terms of their health, safety, privacy and dignity. However, women do not feature in most of the schemes and policies on urban sanitation. The fact that even now the manual scavenging exists, only goes to show that not enough has been done to promote pour-flush toilets and discontinue the use of dry latrines. A more sustained and rigorous campaign needs to be launched towards the right to sanitation on a very large scale. This should primarily focus on the abolition of manual scavenging.

With reference to the above passage, consider the following statements:

  1. 1.Urban sanitation problems can be fully solved by the abolition of manual scavenging only
  2. 2.There is a need to promote greater awareness on safe sanitation practices in urban areas

Which of the statements given above is/are correct?

Answer & explanation

Answer: (b) 2 only

The passage calls for a sustained, large-scale campaign for the right to sanitation, which points to building awareness of safe sanitation. But abolition of manual scavenging is the primary focus, not the only answer — the neglect of women in schemes and dry latrines are problems too — so statement 1 overstates it.

  • ✗ 1. 'Fully solved' and 'only' overstate it; the campaign should 'primarily' focus on abolition, alongside women's needs and pour-flush toilets.
  • ✓ 2. 'A more sustained and rigorous campaign needs to be launched towards the right to sanitation on a very large scale'.

Remember · 'Primarily' is not 'only'. A statement that turns the main focus into the sole solution fails.

Read the passage (Passage—6) — this item is based on it

To understand the nature and quantity of Government proper for man, it is necessary to attend to his character. As nature created him for social life, she fitted him for the station she intended. In all cases she made his natural wants greater than his individual powers. No one man is capable, without the aid of society, of supplying his own wants; and those wants, acting upon every individual, impel the whole of them into society.

Which among the following is the most logical and rational inference that can be made from the above passage?

Answer & explanation

Answer: (d) Diverse natural wants forced man towards social system

Nature made man's wants greater than his individual powers; no one can meet his wants without society, and those wants 'impel the whole of them into society'. So it is man's natural wants that drove him into social life.

  • ✗ (a) Diversity in human society is not discussed.
  • ✗ (b) It is the individual, not society, that cannot meet its wants alone.
  • ✗ (c) It only echoes the premise 'nature created him for social life'; it misses why man became social, which is the passage's point.
  • ✓ (d) 'Those wants, acting upon every individual, impel the whole of them into society'.

Read the passage (Passage—7) — this item is based on it

The nature of the legal imperatives in any given state corresponds to the effective demands that state encounters, and that these, in their turn, depend, in a general way, upon the manner in which economic power is distributed in the society which the state controls.

The statement refers to:

Answer & explanation

Answer: (b) the interrelationship of Politics and Economics

Why not the tempting option · UPSC's key is (b). Option (c) tempts because the law is made to depend on the distribution of economic power, but the dependence is hedged ('corresponds', 'in a general way') and the same sentence has the state controlling the society, so the statement describes a mutual relationship rather than the dominance of economics over politics. In the exam, read the whole sentence: the crux must cover both clauses, not only the one that sounds strongest.

The state's laws answer the demands it faces; those demands depend, in a general way, on how economic power is spread in a society that the state in turn controls. Each side shapes the other, so the statement is about the interrelationship of politics and economics.

  • ✗ (a) Nothing sets politics and economics against each other.
  • ✓ (b) Legal imperatives 'correspond to' demands that 'depend ... upon' the distribution of economic power in a society 'which the state controls': economics shapes the law, and the state controls the society — a two-way link.
  • ✗ (c) The dependence is only 'in a general way', the verb is 'corresponds', and the same sentence has the state controlling the society; a relationship is described, not the dominance of one side over the other.
  • ✗ (d) The statement makes law answer to economic power, not economic power to law.

Remember · When a text says X corresponds to Y 'in a general way' and keeps both sides active, choose 'relationship'; 'predominance' needs an outright claim that one side dominates.

Read the passage (Passage—8) — this item is based on it

About 15 per cent of global greenhouse gas emissions come from agricultural practices. This includes nitrous oxide from fertilizers; methane from livestock, rice production, and manure storage; and carbon dioxide (CO₂) from burning biomass, but this excludes CO₂ emissions from soil management practices, savannah burning and deforestation. Forestry, land use, and land-use change account for another 17 per cent of greenhouse gas emissions each year, three quarters of which come from tropical deforestation. The remainder is largely from draining and burning tropical peatland. About the same amount of carbon is stored in the world's peatlands as is stored in the Amazon rainforest.

Which among the following is the most logical and rational inference that can be made from the above passage?

Answer & explanation

Answer: (b) It is imperative for us to modify our land use practices in order to mitigate climate change

Agriculture gives about 15 per cent of greenhouse gas emissions, and forestry, land use and land-use change another 17 per cent, mostly from tropical deforestation and peatland. With nearly a third of emissions tied to how we use land, changing land use is essential to fighting climate change.

  • ✗ (a) 'Immediately replace ... all over the world' is extreme, and organic farming is never mentioned.
  • ✓ (b) About 15 per cent from agriculture plus another 17 per cent from 'forestry, land use, and land-use change'.
  • ✗ (c) Technology is not discussed at all.
  • ✗ (d) Tropical deforestation appears as a source of emissions; the tropics are not called the chief carbon sinks.

Read the passage (Passage—1) — this item is based on it

As we look to 2050, when we will need to feed two billion more people, the question of which diet is best has taken on new urgency. The foods we choose to eat in the coming decades will have dramatic ramifications for the planet. Simply put, a diet that revolves around meat and dairy, a way of eating that is on the rise throughout the developing world, will take a greater toll on the world's resources than one that revolves around unrefined grains, nuts, fruits and vegetables.

What is the critical message conveyed by the above passage?

Answer & explanation

Answer: (a) Our increasing demand for foods sourced from animals puts a greater burden on our natural resources

As we prepare to feed two billion more people by 2050, the passage says a diet built on meat and dairy — rising across the developing world — takes a greater toll on the world's resources than a plant-based one. The critical message is that growing demand for animal foods burdens natural resources.

  • ✓ (a) A meat and dairy diet 'will take a greater toll on the world's resources'.
  • ✗ (b) The passage weighs the toll on resources, not health.
  • ✗ (c) Habits changing 'irrespective of the health concerns' is not discussed.
  • ✗ (d) The passage does say which diet is lighter on resources; it does not claim ignorance.

Remember · The critical message usually sits in the 'simply put' sentence; reject options that switch the frame, such as health instead of resources.

Read the passage (Passage—2) — this item is based on it

All humans digest mother's milk as infants, but until cattle began being domesticated 10,000 years ago, children once weaned no longer needed to digest milk. As a result, they stopped making the enzyme lactase, which breaks down the sugar lactose into simple sugars. After humans began herding cattle, it became tremendously advantageous to digest milk, and lactose tolerance evolved independently among cattle herders in Europe, the middle East and Africa. Groups not dependant on cattle, such as the Chinese and Thai, remain lactose intolerant.

Which among the following is the most logical assumption that can be made from the above passage?

Answer & explanation

Answer: (b) A permanent change in the food habits of a community can bring about a genetic change in its members

Once herders began drinking milk as adults, lactose tolerance evolved among them, while groups not dependent on cattle stayed intolerant. The passage rests on the idea that a lasting change in a community's diet can bring about a genetic change in its members.

  • ✗ (a) Cattle domestication 10,000 years ago is stated in the passage — a given fact, not the assumption behind its argument.
  • ✓ (b) Lactose tolerance 'evolved' among herders after milk entered their diet; groups 'not dependant on cattle' remain intolerant.
  • ✗ (c) Lactase only breaks lactose into simple sugars; nothing says others cannot get simple sugars — 'only' is unsupported.
  • ✗ (d) 'Any dairy product' is too extreme; the passage speaks only of digesting milk sugar.

Remember · The best assumption links the passage's cause to its effect; options that repeat a stated fact or add 'only' or 'any' are weaker.

“The conceptual difficulties in National Income comparisons between underdeveloped and industrialised countries are particularly serious because a part of the national output in various underdeveloped countries is produced without passing through the commercial channels.”

In the above statement, the author implies that:

Answer & explanation

Answer: (b) the existence of a non-commercialized sector in different underdeveloped countries renders the national income comparisons over countries difficult

The author says national income comparisons between underdeveloped and industrialised countries are hard because part of the underdeveloped countries' output never passes through commercial channels. So the non-commercialised sector is what makes such comparisons difficult.

  • ✗ (a) 'The entire' output of industrialised countries is an overreach the statement does not make.
  • ✓ (b) Output 'produced without passing through the commercial channels' is the stated reason the difficulties are 'particularly serious'.
  • ✗ (c) A prescription ('should') the author never makes.
  • ✗ (d) The author notes where such output exists; he does not call it a sign of underdevelopment.

Read the passage (Passage—4) — this item is based on it

An increase in human-made carbon dioxide in the atmosphere could initiate a chain reaction between plants and microorganisms that would unsettle one of the largest carbon reservoirs on the planet – soil. In a study, it was found that the soil, which contains twice the amount of carbon present in all plants and Earth's atmosphere combined, could become increasingly volatile as people add more carbon dioxide to the atmosphere. This is largely because of increased plant growth. Although a greenhouse gas and a pollutant, carbon dioxide also supports plant growth. As trees and other vegetation flourish in a carbon dioxide-rich future, their roots could stimulate microbial activity in soil that may in turn accelerate the decomposition of soil carbon and its release into the atmosphere as carbon dioxide.

Which among the following is the most logical corollary to the above passage?

Answer & explanation

Answer: (d) Increasing green cover could trigger the release of carbon trapped in soil

More carbon dioxide boosts plant growth, and flourishing roots stimulate soil microbes that speed up the decomposition of soil carbon and its release as carbon dioxide. So an increase in green cover could trigger the release of carbon locked in soil.

  • ✗ (a) The passage says CO₂ 'supports plant growth'; it says nothing about it being essential for microorganisms.
  • ✗ (b) 'Solely' is too strong; human-made CO₂ is one addition, not the only source.
  • ✗ (c) Reverses the chain: plant growth stimulates the microbes, not the other way round.
  • ✓ (d) As vegetation flourishes, 'their roots could stimulate microbial activity in soil that may in turn accelerate the decomposition of soil carbon'.

Remember · Follow the chain the passage builds (CO₂ → plant growth → microbes → soil carbon released); the corollary is its end point.

Read the passage (Passage—5) — this item is based on it

Historically, the biggest challenge to world agriculture has been to achieve a balance between demand for and supply of food. At the level of individual countries, the demand-supply balance can be a critical policy issue for a closed economy, especially if it is a populous economy and its domestic agriculture is not growing sufficiently enough to ensure food supplies, on an enduring basis; it is not so much and not always, of a constraint for an open, and growing economy, which has adequate exchange surpluses to buy food abroad. For the world as a whole, supply-demand balance is always an inescapable prerequisite for warding off hunger and starvation. However, global availability of adequate supply does not necessarily mean that food would automatically move from countries of surplus to countries of deficit if the latter lack in purchasing power. The uneven distribution of hunger, starvation, under- or malnourishment, etc., at the world-level, thus owes itself to the presence of empty-pocket hungry mouths, overwhelmingly confined to the underdeveloped economies. Inasmuch as ‘a two-square meal’ is of elemental significance to basic human existence, the issue of worldwide supply of food has been gaining significance, in recent times, both because the quantum and the composition of demand has been undergoing big changes, and because, in recent years, the capabilities of individual countries to generate uninterrupted chain of food supplies have come under strain. Food production, marketing and prices, especially price-affordability by the poor in the developing world, have become global issues that need global thinking and global solutions.

According to the above passage, which of the following are the fundamental solutions for the world food security problem?

  2. 2.Improving the price affordability by the poor
  3. 3.Regulating the conditions of marketing
