22The Green Revolution in India primarily raised output through which combination of inputs?
introduction to agriculture
Medium
A.Import of foodgrains and price subsidies
B.Land redistribution and cooperative farming
C.Traditional seeds with organic manure only
D.High-yielding variety seeds, irrigation, and chemical fertilizers
Correct Answer: High-yielding variety seeds, irrigation, and chemical fertilizers
Explanation:
The Green Revolution relied on HYV seeds combined with assured irrigation and chemical fertilizers, which sharply raised wheat and rice yields.

23Even though agriculture's share in India's GDP has fallen below , its share in employment remains around . This gap indicates that:
introduction to agriculture
Medium
A.The service sector has shrunk
B.Agriculture is fully mechanized
C.Agricultural labour productivity is high
D.There is disguised unemployment in agriculture
Correct Answer: There is disguised unemployment in agriculture
Explanation:
A high employment share with a low output share means many workers add little to output, a classic sign of disguised unemployment in agriculture.
Incorrect! Try again.
24The Minimum Support Price (MSP) is best described as a policy tool that:
introduction to agriculture
Medium
A.Guarantees farmers a floor price for notified crops
B.Sets export quotas for foodgrains
C.Fixes the interest rate on farm loans
D.Caps the maximum price consumers pay
Correct Answer: Guarantees farmers a floor price for notified crops
Explanation:
MSP is a price floor at which the government commits to purchase crops, protecting farmers from sharp price falls.

25If monsoon rainfall in a year is below normal, which short-run effect on the farm sector is most likely?
introduction to agriculture
Medium
A.Rise in kharif output and lower food prices
B.Increase in agricultural exports
C.Fall in kharif output and upward pressure on food prices
D.No effect because of full irrigation coverage
Correct Answer: Fall in kharif output and upward pressure on food prices
Explanation:
A large share of Indian agriculture is rain-fed, so a deficient monsoon lowers kharif production and tends to push food prices up.
Incorrect! Try again.
26India's growth path is often described as unusual because compared to typical developing economies it:
industrial sector and service sector
Medium
A.Grew services faster than manufacturing
B.Skipped agriculture and moved to industry
C.Never developed a service sector
D.Relied only on public sector output
Correct Answer: Grew services faster than manufacturing
Explanation:
Unlike the classic path of agriculture to manufacturing to services, India saw services leapfrog ahead of a strong manufacturing base.

industrial sector and service sector
Medium
A.High domestic tariffs on software
B.Restrictions on foreign clients
C.Abundant skilled English-speaking labour and cost advantage
D.Heavy reliance on natural resource exports
Correct Answer: Abundant skilled English-speaking labour and cost advantage
Explanation:
A large pool of skilled, English-speaking, cost-competitive workers gave India a comparative advantage in IT and BPO services.
Incorrect! Try again.
31A key concern about India's services-led growth is that it may create jobless growth because:
industrial sector and service sector
Medium
A.Manufacturing employs no one
B.High-skill services absorb relatively few of the low-skilled workforce
C.Services always shrink over time
D.Services need no workers at all
Correct Answer: High-skill services absorb relatively few of the low-skilled workforce
Explanation:
Modern high-value services demand skilled labour, so they cannot absorb the large low-skilled workforce leaving agriculture, causing jobless growth.
Incorrect! Try again.
32The poverty line in India is most commonly defined on the basis of:
Correct Answer: A minimum consumption expenditure meeting calorie needs
Explanation:
The poverty line is set at the consumption expenditure required to obtain a minimum calorie intake, differing for rural and urban areas.
Incorrect! Try again.
33A Gini coefficient rising from to in a country indicates that:
poverty and inequality
Medium
A.Income inequality has increased
B.Income is now perfectly equal
C.Poverty has been eliminated
D.Income inequality has decreased
Correct Answer: Income inequality has increased
Explanation:
The Gini coefficient ranges from (perfect equality) to (perfect inequality), so a higher value means greater inequality.
Incorrect! Try again.
34The Lorenz curve for a country lies further away from the line of equality than another country's curve. This means the first country has:
poverty and inequality
Medium
A.Equal per capita income
B.No poverty
C.Higher inequality
D.Lower inequality
Correct Answer: Higher inequality
Explanation:
The farther the Lorenz curve bows away from the line of perfect equality, the greater the degree of income inequality.
Incorrect! Try again.
35The Head Count Ratio (HCR) of poverty is calculated as:
poverty and inequality
Medium
A.Average income of the poor divided by the poverty line
B.The proportion of population below the poverty line
C.The number of employed persons
D.Total national income divided by population
Correct Answer: The proportion of population below the poverty line
Explanation:
HCR measures the share of the population whose consumption falls below the poverty line; it counts the poor but ignores depth of poverty.
Incorrect! Try again.
36Suppose the poverty line is ₹1,000 per month and three poor persons earn ₹900, ₹700, and ₹500. The Head Count Ratio ignores which important fact captured by the poverty gap?
poverty and inequality
Medium
A.How far below the line each poor person is
B.The total national population
C.Number of people who are poor
D.The average national income
Correct Answer: How far below the line each poor person is
Explanation:
HCR only counts how many are poor, not how deprived they are; the poverty gap measures the shortfall of incomes below the line.
Incorrect! Try again.
37The MGNREGA scheme reduces poverty mainly by:
poverty and inequality
Medium
A.Providing free foodgrains to all citizens
B.Waiving all agricultural taxes
C.Offering interest-free housing loans
D.Guaranteeing wage employment for rural households
Correct Answer: Guaranteeing wage employment for rural households
Explanation:
MGNREGA guarantees up to 100 days of wage employment per rural household, raising incomes and providing a safety net.
Incorrect! Try again.
38The energy-economy-environment (3E) framework highlights the trade-off that faster economic growth often leads to:
emerging energy-economy-environment regulatory framework
Medium
A.No change in emissions
B.Lower energy demand and less pollution
C.Higher energy demand and greater environmental stress
D.Automatic reduction in fossil fuel use
Correct Answer: Higher energy demand and greater environmental stress
Explanation:
Growth raises energy consumption, and if that energy is fossil-based it increases emissions, creating the core 3E trade-off.
Incorrect! Try again.
39A carbon tax works to reduce emissions primarily by:
emerging energy-economy-environment regulatory framework
Medium
A.Banning all industrial activity
B.Raising the private cost of polluting fuels
C.Subsidizing coal consumption
D.Fixing the total quantity of emissions directly
Correct Answer: Raising the private cost of polluting fuels
Explanation:
A carbon tax internalizes the external cost of pollution by making carbon-intensive fuels more expensive, encouraging cleaner alternatives.
Incorrect! Try again.
40Under a cap-and-trade (emissions trading) system, firms that pollute less than their allowance can:
emerging energy-economy-environment regulatory framework
Medium
A.Sell their surplus permits to other firms
B.Be forced to shut down
C.Ignore the emission limit
D.Pay double the carbon tax
Correct Answer: Sell their surplus permits to other firms
Explanation:
Cap-and-trade sets a total emissions cap and allows firms to trade permits, so cleaner firms profit by selling unused allowances.
Incorrect! Try again.
41Despite agriculture's declining share in India's GDP (around –), its share in total employment has remained disproportionately high (around –). This persistent gap is the clearest indicator of which structural problem?
introduction to agriculture
Hard
A.Rising capital intensity across the farm sector
B.Successful structural transformation of the workforce
C.A shrinking net sown area due to urbanisation
D.Low labour productivity and disguised unemployment in agriculture
Correct Answer: Low labour productivity and disguised unemployment in agriculture
Explanation:
When a sector's output share falls far below its employment share, average output per worker is low. It signals disguised unemployment and low labour productivity, meaning workers are trapped in agriculture without proportional value addition.
Incorrect! Try again.
42A state increases Minimum Support Price (MSP) sharply for wheat and rice while leaving pulses and oilseeds untouched. Over several seasons, the most likely distortion is:
Selective MSP support raises the relative return on cereals, incentivising farmers to shift acreage toward wheat and rice. This distorts the cropping pattern and deepens import dependence for pulses and oilseeds.
Incorrect! Try again.
43The Green Revolution raised output but is often criticised for widening regional inequality. Which mechanism best explains this outcome?
introduction to agriculture
Hard
A.HYV technology favoured assured-irrigation regions, concentrating gains in a few states
B.It shifted all gains to rain-fed eastern states first
C.It reduced yields uniformly in every state including Punjab and Haryana
D.It eliminated the need for chemical fertilisers entirely
Correct Answer: HYV technology favoured assured-irrigation regions, concentrating gains in a few states
Explanation:
High-yielding variety seeds needed assured irrigation and fertiliser inputs, so returns concentrated in irrigated belts like Punjab, Haryana and western UP, while rain-fed regions lagged, widening inter-regional disparity.
Incorrect! Try again.
44If the terms of trade move against agriculture (relative prices of farm goods fall versus manufactured inputs), the immediate real-income effect on net-seller farmers is:
introduction to agriculture
Hard
A.A rise in disguised employment on their farms
B.An increase in real income due to cheaper output
C.A decline in their real income as input costs rise relative to output prices
D.No effect since they are price-takers only for inputs
Correct Answer: A decline in their real income as input costs rise relative to output prices
Explanation:
Adverse terms of trade mean farmers receive less for output relative to what they pay for inputs. Net sellers face squeezed margins and falling real income, a recurring concern in Indian farm policy debates.
Incorrect! Try again.
45India is frequently described as having undergone 'premature deindustrialisation'. The core meaning of this term is:
industrial sector and service sector
Hard
A.Manufacturing's share peaked at a lower level and earlier than in advanced economies before declining
B.The service sector never expanded beyond of GDP
C.Industry grew faster than services throughout the reform period
D.Manufacturing employment overtook agricultural employment by 2010
Correct Answer: Manufacturing's share peaked at a lower level and earlier than in advanced economies before declining
Explanation:
Premature deindustrialisation means manufacturing's share of output/employment starts falling at a lower income level and earlier stage than the historical path of today's rich countries, limiting the sector's job-creating potential.
Incorrect! Try again.
46A key criticism of India's growth model is that it 'skipped' the labour-intensive manufacturing stage and leaped to services. The most damaging consequence of this leap is:
industrial sector and service sector
Hard
A.Weak absorption of low-skilled labour exiting agriculture into productive jobs
B.A collapse in the service sector's GDP contribution
C.An oversupply of unskilled workers in high-end IT services
D.A permanent current account surplus from services exports
Correct Answer: Weak absorption of low-skilled labour exiting agriculture into productive jobs
Explanation:
High-skill services (IT, finance) cannot absorb the large pool of low-skilled workers leaving agriculture. Skipping labour-intensive manufacturing leaves this workforce without a productive destination, worsening jobless growth.
Incorrect! Try again.
47Consider two sectors: Sector X has high output growth but flat employment growth; Sector Y has moderate output growth with rising employment. For structural transformation that reduces disguised unemployment, policy should prioritise expanding:
industrial sector and service sector
Hard
A.Neither, since sectoral shares are fixed by comparative advantage
B.Sector Y, because it improves labour absorption from surplus sectors
C.Sector X, because employment growth is irrelevant to transformation
D.Sector X, because higher output always maximises welfare
Correct Answer: Sector Y, because it improves labour absorption from surplus sectors
Explanation:
Structural transformation requires moving surplus labour out of low-productivity agriculture into productive jobs. Sector Y, with rising employment elasticity, absorbs this labour, whereas jobless-growth Sector X does not.
Incorrect! Try again.
48The employment elasticity of output for Indian manufacturing has often been low or falling. If output grows at and employment grows at , the employment elasticity is:
industrial sector and service sector
Hard
A.
B.
C.
D.
Correct Answer:
Explanation:
Employment elasticity . A value well below 1 signals weak job creation per unit of output growth.
Incorrect! Try again.
49A government offers a Production Linked Incentive (PLI) scheme tied to incremental output. A firm qualifies only if it raises production above a baseline. The main economic rationale is to:
industrial sector and service sector
Hard
A.Reward marginal expansion and scale, correcting for competitiveness gaps rather than subsidising existing capacity
B.Replace all import tariffs with direct cash transfers to consumers
C.Guarantee profits regardless of a firm's output performance
D.Discourage capital investment in favour of labour-only firms
Correct Answer: Reward marginal expansion and scale, correcting for competitiveness gaps rather than subsidising existing capacity
Explanation:
PLI incentives are linked to incremental production, so they reward firms that expand output and achieve scale. This targets competitiveness at the margin instead of subsidising pre-existing capacity.
Incorrect! Try again.
50The Gini coefficient for two economies is identical at , yet one has far higher absolute poverty. Which factor best explains how equal inequality can coexist with different poverty levels?
poverty and inequality
Hard
A.Differences in mean income shift the whole distribution relative to the poverty line
B.Poverty and the Gini coefficient always move together
C.The Gini coefficient directly measures the headcount ratio
D.A Gini of fixes the number of poor people
Correct Answer: Differences in mean income shift the whole distribution relative to the poverty line
Explanation:
The Gini measures relative dispersion, not absolute levels. A lower-mean-income economy with the same Gini has more people falling below a fixed poverty line, so equal inequality can coexist with different poverty.
Incorrect! Try again.
51The Head Count Ratio (HCR) is criticised for a specific insensitivity. What is it?
poverty and inequality
Hard
A.It ignores the depth of poverty, treating a person just below the line the same as one far below it
B.It automatically incorporates income inequality among the poor
C.It overstates the intensity of poverty among the ultra-poor
D.It measures only the calorie intake of poor households
Correct Answer: It ignores the depth of poverty, treating a person just below the line the same as one far below it
Explanation:
HCR counts only how many are below the line, not how far below. It is insensitive to poverty gap (depth) and distribution among the poor, which is why the Poverty Gap and FGT indices were developed.
Incorrect! Try again.
52A transfer of income from a poor person just below the poverty line to a much poorer person leaves the Head Count Ratio unchanged but reduces a superior poverty measure. This illustrates which principle?
poverty and inequality
Hard
A.The transfer (Dalton) principle, satisfied by the Poverty Gap/FGT but not by HCR
B.The Engel principle of consumption shares
C.The Lorenz consistency principle applied to GDP
D.The purchasing power parity principle
Correct Answer: The transfer (Dalton) principle, satisfied by the Poverty Gap/FGT but not by HCR
Explanation:
A regressive-to-progressive transfer among the poor should register as reduced poverty. HCR fails this transfer principle; distribution-sensitive measures like the FGT () index satisfy it.
Incorrect! Try again.
53Using the Lorenz curve, if Country A's curve lies entirely inside (closer to the line of equality than) Country B's, we can conclude:
poverty and inequality
Hard
A.Country A necessarily has higher per-capita income
B.Country A has unambiguously lower income inequality than Country B
C.Country B has a lower Gini coefficient
D.The two countries have identical income distributions
Correct Answer: Country A has unambiguously lower income inequality than Country B
Explanation:
If one Lorenz curve lies wholly inside another (Lorenz dominance), it corresponds to lower inequality by every standard measure, including a smaller Gini. It says nothing about absolute income levels.
Incorrect! Try again.
54Economic growth can reduce absolute poverty even while inequality rises. The decomposition of poverty change into two effects identifies these as:
poverty and inequality
Hard
A.A growth (mean-income) effect and a redistribution (inequality) effect
B.A supply shock and a demand shock effect
C.A fiscal effect and a monetary effect
D.A nominal effect and a seasonal effect
Correct Answer: A growth (mean-income) effect and a redistribution (inequality) effect
Explanation:
Poverty change is decomposed into a growth effect (rising mean income lowers poverty) and a redistribution effect (changing inequality). Growth can dominate a worsening redistribution effect, cutting poverty despite rising inequality.
Incorrect! Try again.
55India's climate commitments include reducing 'emissions intensity of GDP'. A country can meet an emissions-intensity target while its absolute emissions still rise. This happens when:
emerging energy-economy-environment regulatory framework
Hard
A.GDP and emissions both remain perfectly constant
B.Emissions intensity is fixed independent of GDP
C.Total emissions fall faster than GDP contracts
D.GDP grows faster than total emissions, lowering emissions per unit of output
Correct Answer: GDP grows faster than total emissions, lowering emissions per unit of output
Explanation:
Emissions intensity . If GDP rises faster than emissions, the ratio falls even as absolute emissions grow. Intensity targets allow continued emission growth alongside economic expansion.
Incorrect! Try again.
56In a Pigouvian framework, the socially optimal level of a polluting activity is where:
emerging energy-economy-environment regulatory framework
Hard
A.Total pollution is driven to zero at any price
B.Marginal social benefit equals marginal social cost, tax set equal to marginal external cost at that point
C.Marginal private benefit is maximised regardless of external cost
D.Marginal private cost equals average revenue only
Correct Answer: Marginal social benefit equals marginal social cost, tax set equal to marginal external cost at that point
Explanation:
A Pigouvian tax internalises the externality by charging the marginal external cost at the optimum, aligning private incentives with the social optimum where marginal social benefit equals marginal social cost, not at zero pollution.
Incorrect! Try again.
57A cap-and-trade (emissions trading) system is generally considered more cost-effective than a uniform command-and-control emission limit because:
emerging energy-economy-environment regulatory framework
Hard
A.It equalises marginal abatement costs across firms via trading, achieving the target at least total cost
B.It guarantees identical abatement cost for all firms by law
C.It forces every firm to cut emissions by the same fixed percentage
D.It removes any overall cap on total emissions
Correct Answer: It equalises marginal abatement costs across firms via trading, achieving the target at least total cost
Explanation:
Trading lets low-cost abaters cut more and sell permits to high-cost firms. In equilibrium marginal abatement costs equalise, so the fixed emissions cap is met at minimum aggregate cost, unlike uniform mandates.
Incorrect! Try again.
58The 'energy trilemma' facing Indian policymakers involves balancing three sometimes-conflicting objectives. These are:
emerging energy-economy-environment regulatory framework
Hard
A.Inflation, unemployment, and growth
B.Taxation, spending, and the fiscal deficit
C.Exports, imports, and the exchange rate
D.Energy security, affordability (equity), and environmental sustainability
Correct Answer: Energy security, affordability (equity), and environmental sustainability
Explanation:
The energy trilemma requires trading off reliable/secure supply, affordable access for consumers, and low environmental impact. Improving one dimension, such as rapid decarbonisation, can strain affordability or security.
Incorrect! Try again.
59Removing fossil-fuel subsidies is often recommended on efficiency grounds but resisted politically. The primary efficiency argument for removal is that subsidies:
emerging energy-economy-environment regulatory framework
Hard
A.Raise the marginal social cost above the market price paid by users
B.Encourage over-consumption by pricing energy below its marginal social cost, worsening the externality
C.Perfectly internalise the negative externality of emissions
D.Reduce total energy demand below the efficient level
Correct Answer: Encourage over-consumption by pricing energy below its marginal social cost, worsening the externality
Explanation:
Subsidies lower the price users pay below marginal social cost, inflating consumption beyond the efficient level and amplifying pollution externalities. Removing them moves prices toward true social cost, improving allocative efficiency.
Incorrect! Try again.
60The Environmental Kuznets Curve (EKC) hypothesis predicts a specific relationship between per-capita income and pollution. That relationship is:
emerging energy-economy-environment regulatory framework
Hard
A.A U-shape: pollution falls then rises with income
B.A flat line independent of income
C.A straight upward line: pollution always rises with income
D.An inverted-U: pollution rises with income, then falls after a turning-point income level
Correct Answer: An inverted-U: pollution rises with income, then falls after a turning-point income level
Explanation:
The EKC posits an inverted-U: at low incomes pollution grows with output, but past a turning point, cleaner technology, structural shifts to services, and demand for environmental quality reduce pollution as income rises further.
