Read the passage

The law in many parts of the world increasingly restricts the discharge of agricultural slurry into watercourses. The simplest and often the most economically sound practice returns the material to the land as semisolid manure or as sprayed slurry. This dilutes its concentration in the environment to what might have occurred in a more primitive and sustainable type of agriculture and converts pollutant into fertilizer. Soil microorganisms decompose the organic components of sewage and slurry and most of the mineral nutrients become available to be absorbed again by the vegetation.
The excess input of nutrients, both nitrogen and phosphorus — based, from agricultural runoff (and human sewage) has caused many ‘healthy’ oligotrophic lakes (low nutrient concentrations, low plant productivity with abundant water weeds, and clear water) to change to eutrophic condition where high nutrient inputs lead to high phytoplankton productivity (sometimes dominated by bloom-forming toxic species). This makes the water turbid, eliminates large plants and, in the worst situations, leads to anoxia and fish kills; so called cultural eutrophication. Thus, important ecosystem services are lost, including the provisioning service of wild-caught fish and the cultural services associated with recreation.
The process of cultural eutrophication of lakes has been understood for some time. But only recently did scientists notice huge ‘dead zones’ in the oceans near river outlets, particularly those draining large catchment areas such as the Mississippi in North America and the Yangtze in China. The nutrient-enriched water flows through streams, rivers and lakes, and eventually to the estuary and ocean where the ecological impact may be huge, killing virtually all invertebrates and fish in areas up to 70,000 km² in extent. More than 150 sea areas worldwide are now regularly starved of oxygen as a result of decomposition of algal blooms, fuelled particularly by nitrogen from agricultural runoff of fertilizers and sewage from large cities. Oceanic dead zones are typically associated with industrialized nations and usually lie off countries that subsidize their agriculture, encouraging farmers to increase productivity and use more fertilizer.

The passage refers to the conversion of “pollutant to fertilizer”. What is pollutant and what is fertilizer in this context ?

Answer (b) & explanation

(b) is correct. Step 1: slurry dumped into watercourses is a pollutant. When returned to land, soil microorganisms decompose it, and 'most of the mineral nutrients become available to be absorbed again by the vegetation'. So decomposed slurry in the soil acts as fertilizer. Step 2: (a) is wrong: microorganisms are the agents that break down the slurry, not the fertilizer itself. Step 3: (c) is wrong: a watercourse cannot be a fertilizer, and spraying slurry on land is the remedy, not the pollution. Since (b) is right, (d) fails.

Tip: in 'what is X and what is Y' questions, check both halves of each option. One wrong half rejects the whole option.

Read the passage

Malnutrition most commonly occurs between the ages of six months and two years. This happens despite the child’s food requirements being less than that of an older child. Malnutrition is often attributed to poverty, but it has been found that even in households where adults eat adequate quantities of food, more than 50 per cent of children-under-five do not consume enough food. The child’s dependence on someone else to feed him/her is primarily responsible for the malnutrition. Very often the mother is working and the responsibility of feeding the young child is left to an older sibling. It is therefore crucial to increase awareness regarding the child’s food needs and how to satisfy them.

According to the author, poverty is not the main cause of malnutrition, but the fact that

  • 1. taking care of younger ones is not a priority for working mothers.
  • 2. awareness of nutritional needs is not propagated by the Public Health authorities.

Select the correct answer using the code given below :

Answer (b) & explanation

Only statement 2 is the key (b). Step 1: the passage says even well-fed families have hungry children, so the real cause is that people do not know a child's food needs. It calls for 'increasing awareness', which suggests awareness is not being spread: the key reads this as statement 2. Step 2: note that the passage never names Public Health authorities, so statement 2 is a loose fit; it is DOUBTFUL, and (d) is arguable. Step 3: statement 1 is wrong: working mothers lack time, so older siblings feed the child; nothing says the child is not a priority for them. So (a) and (c) fail.

Tip: when an option adds a new actor (here, health authorities), check carefully. UPSC sometimes accepts it if the core idea matches.

The excess input of nutrients, both nitrogen and phosphorus — based, from agricultural runoff (and human sewage) has caused many ‘healthy’ oligotrophic lakes (low nutrient concentrations, low plant productivity with abundant water weeds, and clear water) to change to eutrophic condition where high nutrient inputs lead to high phytoplankton productivity (sometimes dominated by bloom-forming toxic species). This makes the water turbid, eliminates large plants and, in the worst situations, leads to anoxia and fish kills; so called cultural eutrophication. Thus, important ecosystem services are lost, including the provisioning service of wild-caught fish and the cultural services associated with recreation.
The process of cultural eutrophication of lakes has been understood for some time. But only recently did scientists notice huge ‘dead zones’ in the oceans near river outlets, particularly those draining large catchment areas such as the Mississippi in North America and the Yangtze in China.

Oceanic dead zones are typically associated with industrialized nations and usually lie off countries that subsidize their agriculture, encouraging farmers to increase productivity and use more fertilizer.

According to the passage, what are the effects of indiscriminate use of fertilizers ?

  • 1. Addition of pollutants to the soil and water.
  • 2. Destruction of decomposer microorganisms in soil.
  • 3. Nutrient enrichment of water bodies.
  • 4. Creation of algal blooms.

Select the correct answer from the codes given below :

Answer (b) & explanation

1, 3 and 4 are correct (b). Step 1: fertilizer runoff adds excess nitrogen and phosphorus to soil and water, which pollutes them (1). Step 2: this nutrient enrichment turns clear lakes eutrophic (3), and the passage says dead zones are caused by 'algal blooms, fuelled particularly by nitrogen from agricultural runoff of fertilizers' (4). Step 3: point 2, destruction of soil decomposers, is never mentioned; the passage actually shows soil microbes working. So (a), (c) and (d) fail.

Tip: list the chain the passage describes: fertilizer → runoff → nutrient-rich water → algal blooms → no oxygen → dead fish. Any effect outside this chain is likely a trap.

Read the passage

A number of empirical studies find that farmers are risk-averse, though only moderately in many cases. There is also evidence to show that farmers’ risk aversion results in cropping patterns and input use designed to reduce risk rather than to maximize income. Farmers adopt a number of strategies to manage and cope with agricultural risks. These include practices like crop and field diversification, non-farm employment, storage of stocks and strategic migration of family members. There are also institutions ranging from share tenancy to kinship, extended family and informal credit agencies. One major obstacle to risk sharing by farmers is that the same type of risks can affect a large number of farmers in the region. Empirical studies show that the traditional methods are not adequate. Hence there is a need for policy interventions, especially measures that cut across geographical regions.
Policies may aim at tackling agricultural risks directly or indirectly. Examples of risk-specific policies are crop insurance, price stabilization and the development of varieties resistant to pests and diseases. Policies which affect risk indirectly are irrigation, subsidized credit and access to information. No single risk-specific policy is sufficient to reduce risk and is without side-effects, whereas policies not specific to risk influence the general situation and affect risks only indirectly. Crop insurance, as a policy measure to tackle agricultural risk directly, deserves careful consideration in the Indian context and in many other developing countries — because the majority of farmers depend on rain-fed agriculture and in many areas yield variability is the predominant cause of their income instability.

The need for policy intervention to mitigate risks in agriculture is because

Answer (c) & explanation

(c) is correct. Step 1: the passage lists farmers' own strategies (diversifying crops, non-farm jobs, storing stocks, migration) and institutions like share tenancy and kinship. Then it says: 'the traditional methods are not adequate. Hence there is a need for policy interventions.' So (c) gives the stated reason. Step 2: (a) is wrong: farmers are only 'moderately' risk-averse, not 'extremely'. (b) is wrong: farmers do know many ways to handle risk. Step 3: (d) is true, but it is the reason crop insurance in particular deserves attention, not the reason for policy intervention in general. So (a), (b) and (d) fail.

Tip: words like 'hence' and 'therefore' link a cause to its result; the sentence before them is the answer.

What is/are the characteristics of a water body with cultural eutrophication ?

  • 1. Loss of ecosystem services
  • 2. Loss of flora and fauna
  • 3. Loss of mineral nutrients

Select the correct answer using the code given below :

Answer (b) & explanation

1 and 2 are correct (b). Step 1: the passage says 'important ecosystem services are lost', such as wild-caught fish and recreation (1). Step 2: it says eutrophication 'eliminates large plants' and leads to anoxia and 'fish kills', so flora and fauna are lost (2). Step 3: point 3 is wrong: eutrophication comes from an excess of nutrients, not a loss of them. So (a), (c) and (d) fail.

Tip: 'eutrophic' means 'well-fed' or nutrient-rich. Any option saying nutrients are lost contradicts the very meaning of the word. Remember: too many nutrients → algae bloom → oxygen falls → plants and fish die.

Which of the following observations emerges from the above passage ?

Answer (b) & explanation

(b) is correct. Step 1: the passage says plainly: 'No single risk-specific policy is sufficient to reduce risk and is without side-effects.' That is (b). Step 2: (a) says one can find a single policy that reduces risk with no side-effect, which is the opposite of the passage. Step 3: (c) is wrong: indirect policies only 'affect risks indirectly'; they do not eliminate risk. (d) is wrong: the passage never says government action can remove risk completely. So (a), (c) and (d) fail.

Tip: options with 'eliminate' and 'completely' are almost always wrong in passages that talk about reducing or managing a problem. Choose the option that repeats the passage's careful wording.

What is the central theme of this passage ?

Answer (c) & explanation

(c) is correct. Step 1: the passage begins with laws on agricultural slurry, then explains how nutrient runoff causes eutrophication of lakes and huge 'dead zones' in the oceans. The common thread is that improper disposal of farm waste damages aquatic ecosystems: (c). Step 2: (a) is wrong: legislation is only mentioned in the first sentence; it is not the theme. Step 3: (b) and (d) are too sweeping: the passage does not blame all of modern agriculture, nor say chemical fertilizers are undesirable in themselves; it even recommends turning slurry into fertilizer. So (a), (b) and (d) fail.

Read the passage

Financial markets in India have acquired greater depth and liquidity over the years. Steady reforms since 1991 have led to growing linkages and integration of the Indian economy and its financial system with the global economy. Weak global economic prospects and continuing uncertainties in the international financial markets therefore, have had their impact on the emerging market economies. Sovereign risk concerns, particularly in the Euro area, affected financial markets for the greater part of the year, with the contagion of Greece’s sovereign debt problem spreading to India and other economies by way of higher-than-normal levels of volatility.
The funding constraints in international financial markets could impact both the availability and cost of foreign funding for banks and corporates. Since the Indian financial system is bank dominated, banks’ ability to withstand stress is critical to overall financial stability. Indian banks, however, remain robust, notwithstanding a decline in capital to risk-weighted assets ratio and a rise in non-performing asset levels in the recent past. Capital adequacy levels remain above the regulatory requirements. The financial market infrastructure continues to function without any major disruption. With further globalization, consolidation, deregulation, and diversification of the financial system, the banking business may become more complex and riskier. Issues like risk and liquidity management and enhancing skill therefore assume greater significance.

According to the passage, the financial markets in the emerging market economies including India had the adverse impact in recent years due to

  • 1. weak global economic prospects.
  • 2. uncertainties in the international financial markets.
  • 3. sovereign risk concerns in the Euro area.
  • 4. bad monsoons and the resultant crop loss.

Select the correct answer using the code given below :

Answer (b) & explanation

1, 2 and 3 are correct (b). Step 1: the passage names 'weak global economic prospects' (1) and 'continuing uncertainties in the international financial markets' (2) as affecting emerging markets. Step 2: it adds that 'sovereign risk concerns, particularly in the Euro area' hit markets, with Greece's debt problem spreading to India (3). Step 3: point 4, bad monsoons and crop loss, is never mentioned. So (a), (c) and (d) fail; (a) and (c) leave out true points, and (d) includes 4.

Tip: in 'select the correct points' questions, tick each point only if you can find it in the passage. A point that sounds reasonable for India (monsoon) but is absent from the text is a trap.

Read the passage

Ecological research over the last quarter of the century has established the deleterious effects of habitat fragmentation due to mining, highways and such other intrusions on forests. When a large block of forests gets fragmented into smaller bits, the edges of all these bits come into contact with human activities resulting in the degradation of the entire forests. Continuity of forested landscapes and corridors gets disrupted affecting several extinction-prone species of wildlife. Habitat fragmentation is therefore considered as the most serious threat to biodiversity conservation. Ad hoc grants of forest lands to mining companies coupled with rampant illegal mining is aggravating this threat.

What is the central focus of this passage ?

Answer (d) & explanation

'Disruption of habitat' is correct (d). Step 1: the passage is about habitat fragmentation: mining and highways break forests into bits, edges are degraded, corridors are cut, and this is 'the most serious threat to biodiversity conservation'. Every sentence returns to the disruption of habitat. Step 2: (a) illegal mining is only one cause, mentioned in the last sentence. (b) extinction of wildlife is one effect. Step 3: (c) conservation of nature is too broad: the passage is about one specific threat, not conservation in general. So (a), (b) and (c) fail.

Tip: the central focus is usually the idea linking the cause and the effect. Options naming only a cause or only an effect are too narrow.

Read the passage

Today’s developing economies use much less energy per capita than developed countries such as the United States did at similar incomes, showing the potential for lower-carbon growth. Adaptation and mitigation need to be integrated into a climate-smart development strategy that increases resilience, reduces the threat of further global warming, and improves development outcomes. Adaptation and mitigation measures can advance development, and prosperity can raise incomes and foster better institutions. A healthier population living in better-built houses and with access to bank loans and social security is better equipped to deal with a changing climate and its consequences. Advancing robust, resilient development policies that promote adaptation is needed today because changes in the climate, already begun, will increase even in the short term.
The spread of economic prosperity has always been intertwined with adaptation to changing ecological conditions. But as growth has altered the environment and as environmental change has accelerated, sustaining growth and adaptability demands greater capacity to understand our environment, generate new adaptive technologies and practices, and diffuse them widely. As economic historians have explained, much of humankind’s creative potential has been directed at adapting to the changing world. But adaptation cannot cope with all the impacts related to climate change, especially as larger changes unfold in the long term.
Countries cannot grow out of harm’s way fast enough to match the changing climate. And some growth strategies, whether driven by the government or the market, can also add to vulnerability — particularly if they overexploit natural resources. Under the Soviet development plan, irrigated cotton cultivation expanded in water-stressed Central Asia and led to the near disappearance of the Aral Sea, threatening the livelihoods of fishermen, herders and farmers. And clearing mangroves — the natural coastal buffers against storm surges — to make way for intensive farming or housing development, increases the physical vulnerability of coastal settlements, whether in Guinea or in Louisiana.

Which of the following conditions is/are necessary for the sustainable economic growth ?

  • 1. Spreading of economic prosperity more.
  • 2. Popularising/spreading of adaptive technologies widely.
  • 3. Investing on research in adaptation and mitigation technologies.

Select the correct answer using the codes given below :

Answer (b) & explanation

Points 2 and 3 are correct (b). Step 1: the passage says sustaining growth 'demands greater capacity to understand our environment, generate new adaptive technologies and practices, and diffuse them widely'. Spreading adaptive technologies (2) and research to create them (3) both follow. Step 2: point 1, spreading prosperity more, is how the paragraph begins its story ('the spread of economic prosperity has always been intertwined with adaptation'). It is described as a fact of history, not named as a condition for sustainable growth. Step 3: so (a), (c) and (d) fail.

Tip: in 'necessary condition' questions, look for words like 'demands', 'requires' or 'needs' in the passage and match the options to what follows them.

Read the passage

Most champions of democracy have been rather reticent in suggesting that democracy would itself promote development and enhancement of social welfare — they have tended to see them as good but distinctly separate and largely independent goals. The detractors of democracy, on the other hand, seemed to have been quite willing to express their diagnosis of what they see as serious tensions between democracy and development. The theorists of the practical split — “Make up your mind : do you want democracy, or instead, do you want development ?” — often came, at least to start with, from East Asian countries, and their voice grew in influence as several of these countries were immensely successful — through the 1970s and 1980s and even later — in promoting economic growth without pursuing democracy.
To deal with these issues we have to pay particular attention to both the content of what can be called development and to the interpretation of democracy (in particular to the respective roles of voting and of public reasoning). The assessment of development cannot be divorced from the lives that people can lead and the real freedom that they enjoy. Development can scarcely be seen merely in terms of enhancement of inanimate objects of convenience, such as a rise in the GNP (or in personal incomes), or industrialization — important as they may be as means to the real ends. Their value must depend on what they do to the lives and freedom of the people involved, which must be central to the idea of development.
If development is understood in a broader way, with a focus on human lives, then it becomes immediately clear that the relation between development and democracy has to be seen partly in terms of their constitutive connection, rather than only through their external links. Even though the question has often been asked whether political freedom is “conducive to development”, we must not miss the crucial recognition that political liberties and democratic rights are among the “constituent components” of development. Their relevance for development does not have to be established indirectly through their contribution to the growth of GNP.

What does a “constitutive” connection between democracy and development imply ?

Answer (c) & explanation

(c) is correct. Step 1: the passage says political liberties and democratic rights are 'among the constituent components of development'. 'Constitutive' means they are part of what development is, not just a cause of it. Step 2: (a) is wrong: the author says the link should be seen 'partly in terms of their constitutive connection, rather than only through their external links'. Step 3: (b) is wrong because of 'only': the passage does not say rights alone lead to economic growth; it says their value need not be shown through GNP at all. Since (c) is right, (d) fails.

Tip: 'constitutive' = 'part of the make-up'. Think of bricks in a wall, not a tool used to build it.

A local man, staying on the top floor of an old wooden house, was awakened at midnight by a fire. Losing his way in a smoke-filled passage, he missed the stairway and went into another room. He picked up a bundle to protect his face from the fire and immediately fell through the floor below where he managed to escape through a clear doorway. The “bundle” proved to be the baby of the Mayor’s wife. The “hero” was congratulated by all.

The man was called a hero because he

Answer (d) & explanation

(d) is correct. Step 1: the 'bundle' he grabbed to protect his face turned out to be the Mayor's baby, and both escaped. So he saved a life, and people called him a hero. Step 2: (a) is wrong: he did not choose to risk his life for others; he grabbed the bundle for his own protection. (b) is wrong: escaping alone would not make him a hero. Step 3: (c) is wrong: he did not fight the fire at all. So (a), (b) and (c) fail.

Tip: the quotation marks round 'hero' and 'bundle' show irony: he saved the baby by accident. Still, the question asks why he was called a hero, and the answer is that a life was saved.

Which of the following inferences can be made from the passage ?

  • 1. Rainfed crops should not be cultivated in irrigated areas.
  • 2. Farming under water-deficient areas should not be a part of development strategy.

Select the correct answer using the codes given below :

Answer (d) & explanation

Neither inference is correct (d). Step 1: statement 1 talks about rainfed crops in irrigated areas. The passage never mentions rainfed crops, so this cannot be inferred. Step 2: statement 2 says farming in water-short areas should not be part of development. The Aral Sea example blames overexploiting water for irrigated cotton, not farming in dry areas as such. Careful farming in such areas is not ruled out. Step 3: so (a), (b) and (c) fail.

Tip: an example in a passage warns against a specific mistake. Do not stretch it into a total ban; 'should not be part of development at all' is far stronger than what the passage says.

Read the passage

The need for Competition Law becomes more evident when foreign direct investment (FDI) is liberalised. The impact of FDI is not always pro-competitive. Very often FDI takes the form of a foreign corporation acquiring a domestic enterprise or establishing a joint venture with one. By making such an acquisition the foreign investor may substantially lessen competition and gain a dominant position in the relevant market, thus charging higher prices. Another scenario is where the affiliates of two separate multinational companies (MNCs) have been established in competition with one another in a particular developing economy, following the liberalisation of FDI. Subsequently, the parent companies overseas merge. With the affiliates no longer remaining independent, competition in the host country may be virtually eliminated and the prices of the products may be artificially inflated. Most of these adverse consequences of mergers and acquisitions by MNCs can be avoided if an effective competition law is in place. Also, an economy that has implemented an effective competition law is in a better position to attract FDI than one that has not. This is not just because most MNCs are expected to be accustomed to the operation of such a law in their home countries and know how to deal with such concerns but also that MNCs expect competition authorities to ensure a level playing field between domestic and foreign firms.

With reference to the passage, consider the following statements :

  • 1. It is desirable that the impact of Foreign Direct Investment should be pro-competitive.
  • 2. The entry of foreign investors invariably leads to the inflated prices in domestic markets.

Which of the statements given above is/are correct ?

Answer (a) & explanation

Only statement 1 is correct (a). Step 1: the passage begins by saying the impact of FDI 'is not always pro-competitive' and shows how it can harm competition. This implies it is desirable for FDI to be pro-competitive: 1 is right. Step 2: statement 2 says foreign entry invariably inflates prices. The passage says a dominant investor 'may' charge higher prices and prices 'may be artificially inflated' in certain cases like mergers. 'May' is not 'always', so 2 is wrong. Step 3: hence (b), (c) and (d) fail.

Tip: 'invariably', 'always' and 'never' need equally strong words in the passage. If the passage says 'may' or 'can', the strong option fails.

Today’s developing economies use much less energy per capita than developed countries such as the United States did at similar incomes, showing the potential for lower-carbon growth. Adaptation and mitigation need to be integrated into a climate-smart development strategy that increases resilience, reduces the threat of further global warming, and improves development outcomes. Adaptation and mitigation measures can advance development, and prosperity can raise incomes and foster better institutions. A healthier population living in better-built houses and with access to bank loans and social security is better equipped to deal with a changing climate and its consequences. Advancing robust, resilient development policies that promote adaptation is needed today because changes in the climate, already begun, will increase even in the short term.
The spread of economic prosperity has always been intertwined with adaptation to changing ecological conditions. But as growth has altered the environment and as environmental change has accelerated, sustaining growth and adaptability demands greater capacity to understand our environment, generate new adaptive technologies and practices, and diffuse them widely. As economic historians have explained, much of humankind’s creative potential has been directed at adapting to the changing world. But adaptation cannot cope with all the impacts related to climate change, especially as larger changes unfold in the long term.
Countries cannot grow out of harm’s way fast enough to match the changing climate. And some growth strategies, whether driven by the government or the market, can also add to vulnerability — particularly if they overexploit natural resources. Under the Soviet development plan, irrigated cotton cultivation expanded in water-stressed Central Asia and led to the near disappearance of the Aral Sea, threatening the livelihoods of fishermen, herders and farmers. And clearing mangroves — the natural coastal buffers against storm surges — to make way for intensive farming or housing development, increases the physical vulnerability of coastal settlements, whether in Guinea or in Louisiana.

Consider the following assumptions :

  • 1. Sustainable economic growth demands the use of creative potential of man.
  • 2. Intensive agriculture can lead to ecological backlash.
  • 3. Spread of the economic prosperity can adversely affect the ecology and environment.

With reference to the passage, which of the above assumptions is/are valid ?

Answer (d) & explanation

All three assumptions are valid (d). Step 1: the passage says 'much of humankind's creative potential has been directed at adapting', and sustaining growth needs new adaptive technologies. So growth depends on human creativity: 1 is valid. Step 2: irrigated cotton led to the 'near disappearance of the Aral Sea', and mangroves were cleared for intensive farming. Intensive agriculture can backfire on ecology: 2 is valid. Step 3: it also says 'growth has altered the environment' and some growth strategies 'add to vulnerability'. So spreading prosperity can harm ecology: 3 is valid. Hence (a), (b) and (c) fail.

Tip: an assumption is valid if the passage takes it for granted or shows it through an example.

The need for Competition Law becomes more evident when foreign direct investment (FDI) is liberalised. The impact of FDI is not always pro-competitive. Very often FDI takes the form of a foreign corporation acquiring a domestic enterprise or establishing a joint venture with one. By making such an acquisition the foreign investor may substantially lessen competition and gain a dominant position in the relevant market, thus charging higher prices. Another scenario is where the affiliates of two separate multinational companies (MNCs) have been established in competition with one another in a particular developing economy, following the liberalisation of FDI. Subsequently, the parent companies overseas merge. With the affiliates no longer remaining independent, competition in the host country may be virtually eliminated and the prices of the products may be artificially inflated. Most of these adverse consequences of mergers and acquisitions by MNCs can be avoided if an effective competition law is in place. Also, an economy that has implemented an effective competition law is in a better position to attract FDI than one that has not. This is not just because most MNCs are expected to be accustomed to the operation of such a law in their home countries and know how to deal with such concerns but also that MNCs expect competition authorities to ensure a level playing field between domestic and foreign firms.

According to the passage, how does a foreign investor dominate the relevant domestic market ?

  • 1. Multinational companies get accustomed to domestic laws.
  • 2. Foreign companies establish joint ventures with domestic companies.
  • 3. Affiliates in a particular market/sector lose their independence as their parent companies overseas merge.
  • 4. Foreign companies lower the cost of their products as compared to that of products of domestic companies.

Which of the statements given above are correct ?

Answer (b) & explanation

2 and 3 are correct (b). Step 1: the passage says a foreign investor may gain a dominant position by acquiring a domestic firm or setting up a joint venture with one (2). Step 2: it also says when parent MNCs overseas merge, their local affiliates stop competing and competition 'may be virtually eliminated' (3). Step 3: statement 1 is wrong: MNCs are used to competition law in their home countries, and that is a reason they invest, not how they dominate. Statement 4 is wrong: dominance leads to higher prices, not lower costs. So (a), (c) and (d) fail.

Tip: answer the exact question ('how does it dominate') and ignore true facts that answer a different one.

Which one of the following statements constitutes central theme of this passage ?

Answer (b) & explanation

'Integrate adaptation and mitigation with development' is correct (b). Step 1: the passage's key sentence is: 'Adaptation and mitigation need to be integrated into a climate-smart development strategy.' Everything else supports this point. Step 2: (a) is true (healthier, better-housed people cope better), but it is a supporting detail, not the main theme. (d) is also only an example (Aral Sea, mangroves). Step 3: (c) is wrong: the passage never says growth should not be pursued; it wants better, climate-smart growth. So (a), (c) and (d) fail.

Tip: the central theme is usually a broad 'need to' or 'should' sentence. Examples and supporting facts are true but too narrow to be the theme.

What is the inference from this passage ?

Answer (c) & explanation

(c) is correct. Step 1: the passage says most harms of MNC mergers 'can be avoided if an effective competition law is in place', and that MNCs expect competition authorities to 'ensure a level playing field between domestic and foreign firms'. Step 2: (a) is wrong because of 'always': the passage only describes situations where foreign firms may dominate. Step 3: (b) is wrong: the passage does not oppose mergers as such; it wants them checked by competition law. (d) is wrong: whether FDI is essential for growth is never discussed. So (a), (b) and (d) fail.

Tip: the best inference usually echoes the passage's conclusion (here, the value of competition law). Options with 'always' or new topics are traps.

Read the passage

Invasions of exotic species into new geographic areas sometimes occur naturally and without human agency. However, human actions have increased this trickle to a flood. Human-caused introductions may occur either accidentally as a consequence of human transport, or intentionally but illegally to serve some private purpose or legitimately to procure some hoped-for public benefit by bringing a pest under control, producing new agricultural products or providing novel recreational opportunities. Many introduced species are assimilated into communities without much obvious effect. However, some have been responsible for dramatic changes to native species and natural communities. For example, the accidental introduction of the brown tree snake Boiga irregularis into Guam, an island in the Pacific, has through nest predation reduced 10 endemic forest bird species to the point of extinction.
One of the major reasons for the world’s great biodiversity is the occurrence of centers of endemism so that similar habitats in different parts of the world are occupied by different groups of species that happen to have evolved there. If every species naturally had access to everywhere on the globe, we might expect a relatively small number of successful species to become dominant in each biome. The extent to which this homogenization can happen naturally is restricted by the limited powers of dispersal of most species in the face of the physical barriers that exist to dispersal. By virtue of the transport opportunities offered by humans, these barriers have been breached by an ever-increasing number of exotic species. The effects of introductions have been to convert a hugely diverse range of local community compositions into something much more homogeneous.
It would be wrong, however, to conclude that introducing species to a region will inevitably cause a decline in species richness there. For example, there are numerous species of plants, invertebrates and vertebrates found in continental Europe but absent from the British Isles (many because they have so far failed to recolonize after the last glaciations). Their introduction would be likely to augment British biodiversity. The significant detrimental effect noted above arises where aggressive species provide a novel challenge to endemic biotas ill-equipped to deal with them.

With reference to the passage, which of the following statements is correct ?

Answer (d) & explanation

None of the statements is correct (d). Step 1: (a) says introductions always reduce biodiversity. The passage says this is 'wrong' and that bringing continental species to Britain would 'augment British biodiversity'. Step 2: (b) says introduced species have always greatly changed native systems. The passage says 'many introduced species are assimilated without much obvious effect'. Step 3: (c) says man is the only cause of homogenization. The passage says invasions also 'occur naturally', even if humans turned the trickle into a flood. So (a), (b) and (c) all fail.

Tip: words like 'always' and 'only' in options are warning signs. One counter-example in the passage is enough to reject them.

Read the passage

The poor especially in market economies, need the strength that collectivities offer for creating more economic, social and political space for themselves, for enhancing their socio-economic well-being and voice, and as a protection against free market individualism. It has been argued that a group approach to farming, especially in the form of bottom up agricultural production collectivities, offers substantial scope for poverty alleviation and empowering the poor as well as enhancing agricultural productivity. To realise this potential, however, the groups would need to be voluntary in nature, small in size, participative in decision making and equitable in work sharing and benefit distribution. There are many notable examples of such collectivities to be found in varied contexts, such as in the transition economies. All of them bear witness to the possibility of successful cooperation under given conditions. And although the gender impact of the family cooperatives in the transition economies are uncertain, the Indian examples of women-only groups farming offer considerable potential for benefiting women.

Agricultural collectivities such as group based farming can provide the rural poor

  • 1. empowerment.
  • 2. increased agricultural productivity.
  • 3. safeguard against exploitative markets.
  • 4. surplus production of agricultural commodities.

Select the correct answer using the codes given below :

Answer (b) & explanation

1, 2 and 3 are correct (b). Step 1: the passage says group farming offers scope for 'empowering the poor' (1) and 'enhancing agricultural productivity' (2). Step 2: it says collectivities give the poor 'a protection against free market individualism'. That is a safeguard against harsh, exploitative markets (3). Step 3: point 4, surplus production, is never claimed. Higher productivity does not mean a surplus beyond needs. So (a), (c) and (d), which include 4 or leave out 1, fail.

Tip: separate what the passage says from what might follow from it. 'More productive' is stated; 'surplus' is your own extra step, and UPSC usually rejects such steps.
