UGC NET Questions (Paper – 1)

Sustainable development is often described as having economic,social and environmental dimensions. Micro credit schemes focus on improving incomes,livelihood security and economic opportunities for the poor. The stem refers to small loans for income generating activities,which clearly target the economic dimension. Therefore Option C is the correct answer.

Option A:
Environmental improvements can be an indirect result of reduced poverty,but micro credit’s main objective is economic empowerment. So Option A does not capture the primary focus mentioned in the question.

Option B:
Cultural aspects of development relate to identity,heritage and values. While important,they are not the main emphasis of micro finance schemes described here.

Option C:
Technological changes can support micro enterprises,but the key dimension being strengthened is the economic base of households. Hence Option D is not as accurate as Option C.

Option D:
Economic strengthening through micro credit can also support social and environmental goals,but in the triad of sustainable development dimensions,this intervention is most directly economic.

Greenhouse gases are those that can absorb and emit infrared radiation, contributing to the greenhouse effect. Carbon dioxide from fossil fuels and deforestation, methane from agriculture and waste, and nitrous oxide from fertilisers are key anthropogenic drivers of current climate change. They have increased significantly in concentration since the industrial revolution.

Option A:
Option A is incorrect because nitrogen, oxygen and argon are major components of air but are not strong greenhouse gases under normal conditions.

Option B:
Option B is correct as it lists three important long-lived greenhouse gases recognised in international climate agreements.

Option C:
Option C is incorrect since neon, helium and krypton are inert gases with negligible greenhouse effect.

Option D:
Option D is incorrect because hydrogen, neon and argon are not principal contributors to observed warming.

In implementing the Kunming–Montreal Framework, parties have converged on the need to mobilise about USD 200 billion annually for biodiversity by 2030. A part of this is to come from international flows to developing countries, with commitments to scale support from roughly USD 20 billion a year by 2025 to around USD 30 billion by 2030. This level of finance is considered necessary to meet targets such as the “30×30” goal and restoration of degraded ecosystems. The figure also reflects efforts to integrate biodiversity into broader public and private financial systems. (AP News)

Option A:
This amount is too low and does not reflect the scale of ambition in the current biodiversity finance discussions. It understates what is considered necessary for implementing global targets, especially in developing countries.

Option B:
This option exaggerates the focus on high-income countries as recipients and misstates the scale of funding. In reality, a substantial share of new resources is intended for developing countries where biodiversity is richest and capacity gaps are larger.

Option C:
Linking a figure of USD 100 billion solely to climate projects confuses biodiversity finance with climate finance under the UNFCCC. Although there are overlaps, the Kunming–Montreal Framework requires dedicated biodiversity resources, not just climate-labelled funding.

Option D:
This option is correct because it matches the order of magnitude and structure of the finance package discussed in recent COP16-related negotiations. It notes both the overall annual target (around USD 200 billion) and the specific rising commitments to developing countries, which are central for equity.

Environmental ethics deals with questions about how humans ought to relate to nature. It explores whether non human entities have moral standing and what responsibilities we have to future generations. This field informs debates on conservation,development and animal rights. Hence the definition in the question matches environmental ethics.

Option A:
Business ethics examines moral issues in the world of commerce,such as fairness,honesty and corporate responsibility. While it may touch on environmental issues,it is not primarily about human nature relationships. Therefore it is not the correct answer.

Option B:
Bioethics addresses ethical questions in medicine and life sciences,including topics like clinical trials,organ transplantation and genetic engineering. Its main focus is on human health and biomedical research. Thus it differs from the broader nature centred concerns in the stem.

Option C:
Environmental ethics specifically investigates the moral dimensions of pollution,biodiversity loss and resource use. It challenges purely anthropocentric views and considers ecocentric or biocentric perspectives. This focus matches the description in the question.

Option D:
Social ethics concerns justice,rights and responsibilities within human societies. Although environmental issues have social implications,social ethics alone does not concentrate on duties toward the natural world. Therefore it is not the best term here.

Rooftop rainwater harvesting captures precipitation that would otherwise quickly run off impervious surfaces. When this water is stored or directed into recharge structures, local aquifers can be replenished and dependence on external sources can be reduced. At the same time, diverting water away from streets and drains lessens peak runoff and helps mitigate urban flooding during heavy rains. For these reasons, the statement that it helps recharge groundwater and reduce flooding correctly summarises its main environmental benefits.

Option A:
Option A is incorrect because harvesting local rainwater tends to reduce, not increase, reliance on distant reservoirs and long pipelines. By using water where it falls, cities can lower the strain on regional river systems and energy-intensive water transfers.

Option B:
Option B is incorrect as effective recharge practices are designed to stabilise or raise groundwater levels, not to lower them. Lowering usually results from over-extraction or insufficient replenishment, the opposite of what rainwater harvesting seeks to achieve.

Option C:
Option C is incorrect because properly designed rooftop systems intercept rainfall before it becomes surface runoff, then channel it into storage tanks or recharge pits. This reduces the volume of water rushing across roads and into storm drains, thereby helping to manage runoff.

Option D:
Option D is correct since it combines the conservation and flood-control roles of rainwater harvesting. Implementing such systems at scale is an important adaptation strategy in water-stressed and flood-prone urban regions.

Statement C is wrong because urbanisation does not always reduce pressure on rural and peri-urban areas; in fact, urban demand often increases extraction of resources and conversion of land outside cities. Statements A, B and D are correct: urbanisation can raise resource demand, compact forms can lower per capita use and urban consumption patterns shape wider ecological footprints. Therefore, the option that selects C alone as wrong is correct.

Option A:
Option A is incorrect because it treats both A and C as wrong, even though A is a true statement about increased resource demand with urban growth. Including a correct statement among wrong ones makes the option unacceptable.

Option B:
Option B is incorrect as it groups C and D as wrong. While C is indeed wrong, D is correct since city consumption influences regional and global ecological footprints through resource flows and waste.

Option C:
Option C is correct because it isolates C as the only incorrect statement and implicitly recognises A, B and D as accurate. It matches the requirement for selecting wrong statement(s).

Option D:
Option D is incorrect because it labels all four statements as wrong. This misrepresents three correct statements about urbanisation and its environmental implications.

Inclusive growth is concerned with who benefits from economic expansion, not just how fast the economy grows. It emphasises that new opportunities and incomes should reach disadvantaged groups, reduce poverty and narrow inequalities. Policies under this approach try to combine high growth with broad-based improvements in livelihoods and access to services. Therefore, the description that stresses widely shared benefits among all sections of society correctly expresses the core idea of inclusive growth.

Option A:
Option A is incorrect because growth confined to export-oriented industries can leave large parts of the population behind. Without linkages to employment, social protection and rural development, such growth may increase inequality instead of inclusion.

Option B:
Option B is incorrect since growth that raises only government revenue may or may not improve people’s welfare. Without equitable spending and redistribution, higher revenue alone cannot ensure inclusive outcomes.

Option C:
Option C is correct as it refers to the spread of benefits across different social and regional groups. It recognises that growth must translate into better jobs, services and opportunities for the poor and marginalised, not just higher averages.

Option D:
Option D is incorrect because unregulated exploitation of natural resources can harm the environment and the livelihoods of vulnerable communities. Such growth may be rapid but neither inclusive nor sustainable.

Minamata disease occurred when industrial effluents containing methylmercury were discharged into Minamata Bay. The mercury entered the food chain, accumulated in fish and shellfish and then poisoned local residents who consumed them. The disease caused neurological damage and deformities. Therefore mercury is the substance responsible as indicated in the stem.

Option A:
Lead exposure can cause serious health problems, especially in children, but it was not the primary contaminant in the Minamata incident. Lead poisoning is associated with different industrial and domestic sources, so this option is incorrect.

Option B:
Cadmium pollution led to another famous Japanese disease,Itai-itai disease, characterised by severe bone and kidney damage. This historical linkage distinguishes cadmium from mercury in the context of Minamata. Hence cadmium is not the right answer here.

Option C:
Mercury,particularly in organic forms like methylmercury,readily bioaccumulates and biomagnifies in aquatic food chains. The Minamata tragedy is a classic example of such contamination leading to widespread human health impacts. This option exactly matches the pollutant referred to in the question.

Option D:
Arsenic contamination has caused major groundwater health crises in places like West Bengal and Bangladesh,leading to skin lesions and cancers. However,it is unrelated to the specific historical Minamata disease.

Over a 100-year period, nitrous oxide has a much higher global warming potential per unit mass than carbon dioxide or methane, so each kilogram emitted traps far more heat.

Option A:
Incorrect; carbon dioxide is used as the reference gas with a GWP of 1 and has lower GWP per unit mass than nitrous oxide, even though its total impact is large due to volume emitted.

Option B:
Incorrect; methane has higher GWP than CO₂ but still lower than nitrous oxide on a 100-year horizon.

Option C:
Incorrect; although water vapour is an important greenhouse gas, it is not usually assigned a standard GWP in this way and is strongly controlled by temperature.

Option D:
Correct; nitrous oxide has the highest GWP among the listed gases over a 100-year time frame.

When people move from countryside villages to town and city areas,they are moving from rural to urban settlements. The stem describes young people leaving villages for jobs in cities,which fits this pattern exactly. Hence “rural to urban” migration is the correct term. It is a key driver of urbanisation.

Option A:
Seasonal migration refers to temporary movements that are reversed after a season,such as harvest or construction seasons. The question does not specify temporary or cyclical movement,so Option A is not precise.

Option B:
Rural to urban migration is often permanent or long term and changes the demographic structure of both origin and destination. This describes the flow mentioned in the stem accurately.

Option C:
Return migration occurs when migrants go back to their native place after some time in the destination area. The stem does not talk about returning,so Option C is not appropriate.

Option D:
Forced migration involves coercion due to conflict or disasters. The question mentions voluntary job-seeking migration,so Option D is incorrect.

Statements A, B and D are correct because they reflect the role of communities and ecological functions of forests. A captures the participatory nature of JFM, B points to the multiple ecological and livelihood services provided by forests and D notes how community management can help conserve biodiversity. Statement C is incorrect since deforestation does affect the hydrological cycle, influencing rainfall, runoff and water availability. Therefore, the correct answer is the combination that includes A, B and D only.

Option A:
Option A is incorrect because it includes only A and B and leaves out D. While A and B are true, D is also correct in recognising that community-based management supports biodiversity conservation. Omitting a correct statement makes this combination incomplete.

Option B:
Option B is incorrect because it joins A and D but excludes B. Statement B is a core idea about ecosystem services of forests, so leaving it out fails to represent the full set of correct statements about forest resources. As a result, this option is not satisfactory.

Option C:
Option C is correct because it identifies that A, B and D are all valid statements while C is false. It maintains the link between forests, ecological services and community-based conservation approaches. By excluding C, it preserves internal consistency with ecological science.

Option D:
Option D is incorrect because it includes B, C and D and thus accepts C as correct. Since C wrongly minimises the impact of deforestation on water cycles, the combination cannot be chosen despite including B and D.

Minamata disease was traced to industrial effluents containing methyl mercury, a highly toxic organic form of mercury. These compounds entered coastal waters, bioaccumulated in fish and shellfish and then biomagnified up the food chain to humans. People consuming contaminated seafood developed severe neurological symptoms, including loss of coordination and sensory disturbances. The disaster became a landmark case highlighting the dangers of toxic heavy metal pollution, particularly methyl mercury, in aquatic environments. Therefore, Option B is correct.

Option A:
Option A is incorrect because arsenic poisoning is associated with other incidents and diseases, such as skin lesions and cancers in areas with arsenic-contaminated groundwater. It is not the agent linked with Minamata disease.

Option B:
Option B is correct as it specifies methyl mercury compounds, which are fat-soluble and easily bioaccumulate in aquatic organisms. This particular form of mercury was central to the Minamata tragedy and its health impacts.

Option C:
Option C is incorrect because fluoride, while harmful in excess, does not produce the characteristic neurological symptoms seen in Minamata patients. Its effects are mostly on bones and teeth.

Option D:
Option D is incorrect as radioactive iodine is associated with nuclear accidents and thyroid problems, not with the specific industrial mercury pollution that caused Minamata disease.

Amrit Dharohar seeks to derive multiple benefits from wetlands while ensuring their ecological health. The scheme focuses on Ramsar sites, encouraging local communities to engage in sustainable activities such as bird-watching tourism, traditional fisheries and handicrafts. This approach recognises wetlands as natural assets that support biodiversity, water regulation and livelihoods. It fits well within the people-development-environment nexus of Unit-IX.

Option A:
This option is incorrect because converting wetlands to real estate generally destroys their ecological functions. The scheme is meant to prevent such degradation.

Option B:
This option correctly captures the idea of community-based conservation and livelihood generation around Ramsar wetlands, which is central to Amrit Dharohar.

Option C:
Draining wetlands for intensive farming would contradict the scheme’s conservation objectives and harm biodiversity and flood regulation services.

Option D:
Fertiliser subsidies are not the main focus; the scheme emphasises sustainable use and ecosystem services rather than input subsidies.

Corporate social responsibility refers to a company’s commitment to operate ethically and contribute to economic development while improving the quality of life of its workforce,their families and the community. It includes attention to environmental performance,social equity and stakeholder interests beyond legal requirements. Thus the description in the question corresponds to corporate social responsibility.

Option A:
Consumerism is both a social movement advocating fair rights for consumers and a culture of high consumption. It does not primarily denote firms voluntarily integrating environmental and social concerns in their strategies. Therefore it is not the most suitable answer.

Option B:
Globalisation describes increasing interconnectedness of economies,cultures and societies across the world. While it affects corporate behaviour,it is not itself a norm about integrating social and environmental considerations. Hence it does not match the concept in the stem.

Option C:
Market liberalisation involves reducing state restrictions on economic activities to promote free markets. It focuses on regulatory reform rather than ethical responsibilities of firms. Consequently,it is not the idea captured in the question.

Option D:
Corporate social responsibility encourages companies to go beyond profit maximisation and legal compliance. It promotes initiatives such as reducing emissions,ensuring worker safety and supporting community development. These voluntary actions fit the description in the question.

Common property resources are held and used collectively by a defined community under shared rules. Village grazing lands are typically accessed by many households and managed through community norms or institutions.

Option A:
Option A is correct as it illustrates a resource whose use and management are shared among community members, fitting the classic definition of common property.

Option B:
Option B is incorrect because a privately owned tube-well is controlled by an individual or family and others can be excluded, so it is private property.

Option C:
Option C is incorrect as a personal computer is normally owned and used by one person or household, not governed by community rules.

Option D:
Option D is incorrect since a petrol pump is a commercial, privately operated business where access is based on market transactions rather than communal rights.
