UGC NET Questions (Paper – 1)

Statements A, B, D and E are correct as they reflect key equity principles, attention to historical responsibility, debates on loss and damage, and links between climate action and labour rights. Statement C is false because climate justice explicitly highlights inequalities within countries, including impacts on poor and marginalised communities. Statement F is also false since justice concerns extend to adaptation, resilience and recovery from climate impacts. Hence, the combination that includes A, B, D and E and excludes C and F is correct.

Option A:
Option A is incorrect as it omits E, thereby ignoring the just transition agenda, which is an important part of contemporary climate justice discussions about workers and livelihoods.

Option B:
Option B is incorrect because it includes F, which wrongly narrows climate justice to mitigation only, and it still excludes E. Including F mixes a false statement with true ones.

Option C:
Option C is correct since it captures principles, debates and emerging concepts like loss and damage and just transition, while rejecting statements that minimise intra-country inequalities or adaptation concerns.

Option D:
Option D is incorrect because it leaves out A, so it fails to mention the core principle of common but differentiated responsibilities and capabilities, which is fundamental for understanding equity in climate regimes.

Statements A, B and C are correct because they express recognised ecological functions of wetlands and the role of the Ramsar Convention. Wetlands support rich biodiversity including migratory birds, help filter pollutants and moderate floods and are the focus of an international treaty on their conservation and wise use. Statement D is incorrect as wetlands are crucial for maintaining regional biodiversity. Therefore, the correct combination is A, B and C only.

Option A:
Option A is correct since it includes all the true statements and excludes D, which denies the biodiversity role of wetlands. It presents a comprehensive view of wetland functions and governance. Hence, it satisfies the requirement of the question.

Option B:
Option B is incorrect as it claims that all four statements are correct. Accepting D would wrongly downplay the importance of wetlands for biodiversity. Including a false statement invalidates the option.

Option C:
Option C is incomplete because it includes only A and B and omits C. While A and B are valid, C is also true and specifically mentions the international legal framework for wetlands. The omission makes this option insufficient.

Option D:
Option D is incorrect because it accepts D along with B and C and leaves out A. Statement D is false, and excluding A misses the direct link between wetlands and wildlife habitat, so the option cannot be chosen.

Statements A, B and D correctly summarise IQAC’s functions. It coordinates internal quality processes, prepares reports like the AQAR and organises capacity-building activities on quality themes for faculty and staff. Statements C, E and F are incorrect because IQAC continues to function after accreditation, should collaborate widely across the institution and its documentation is vital for planning and review.

Option A:
Option A is incorrect because it includes only A and B and omits D, thereby underplaying the role of IQAC in organising workshops and sensitisation programmes.

Option B:
Option B is incorrect because it includes only B and D and omits A, so it does not state explicitly that IQAC coordinates overall internal quality assurance.

Option C:
Option C is correct because it combines A, B and D and excludes C, E and F.

Option D:
Option D is incorrect because it includes C (false), which wrongly claims IQAC becomes redundant after accreditation.

Statement D is the only wrong statement because pollution often moves across media, for example air pollutants depositing onto land or water and leachates from solid waste affecting groundwater. Statements A, B, C, E and F are correct in describing typical pollution pathways and the rationale for integrated management. Water quality, soil health and air quality are interconnected through ecological and physical processes. Therefore, identifying D alone as wrong is the correct response.

Option A:
Option A is incorrect because it treats both A and D as wrong, even though A correctly notes the impacts of industrial effluents on water quality and aquatic ecosystems. Including A among wrong statements contradicts basic environmental science.

Option B:
Option B is incorrect since it groups D and E as wrong together. E is correct in explaining how open dumping contaminates soil and invites vectors, so pairing it with D mislabels a valid statement.

Option C:
Option C is incorrect because it labels B and D as wrong. B accurately describes contamination from overuse of fertilisers and pesticides, which is a well-known source of soil and groundwater pollution.

Option D:
Option D is correct as it singles out D, which wrongly denies cross-media linkages, and implicitly recognises all other statements as true. It aligns with the integrated approach promoted in pollution management.

Biomagnification occurs when persistent pollutants that are not easily broken down accumulate as they move up food chains. Small organisms take up low concentrations from water, but predators eat many contaminated prey. At each trophic level, the pollutant concentration in tissues becomes higher. The highest levels are often found in top predators, such as fish-eating birds, which is exactly what the correct statement describes.

Option A:
Option A is incorrect because water usually contains relatively low concentrations of DDT compared to living organisms. It is in organisms, not in the water itself, that concentrations tend to build up.

Option B:
Option B is incorrect since saying concentrations decrease at higher trophic levels reverses the observed pattern. That would imply biodilution, not biomagnification.

Option C:
Option C is correct because it shows increasing concentration from plankton to fish and then birds. This pattern explains why eggshell thinning was observed in birds exposed to DDT through aquatic food chains.

Option D:
Option D is incorrect because DDT is known for its persistence and slow breakdown. Its ability to enter and stay in organisms is the reason biomagnification occurs.

Statements A, B, C and E are correct because they describe how unplanned urbanisation produces informal settlements, how hazardous locations increase risk, how upgrading reduces environmental health problems and how participation improves interventions. Statement D is wrong because urban planning is central to addressing service inequalities. Statement F is also wrong, since slum-related environmental problems can affect entire urban systems through pollution and disease. Therefore, the option that retains A, B, C and E while excluding D and F is correct.

Option A:
Option A is incorrect because it omits E, thereby missing the important point that inclusive planning involves participation of slum residents in designing interventions.

Option B:
Option B is incorrect as it includes D, thereby treating a false claim about planning as correct. It also omits E, which recognises the importance of involving slum residents in decision-making.

Option C:
Option C is incorrect since it keeps D and excludes A. Losing A removes recognition of how rapid urbanisation generates informal settlements, while retaining D wrongly minimises the role of planning.

Option D:
Option D is correct as it keeps all true statements and excludes both D and F, which underestimate planning responsibilities and city-wide impacts. It aligns with inclusive and environmentally sensitive urban development.

Human development interprets development as enlarging people’s capabilities and freedoms in areas such as health, education and participation, going beyond income or output alone.

Option A:
Incorrect; equating development solely with GDP ignores non-income dimensions like health, education and empowerment.

Option B:
Incorrect; stock market performance and foreign investment are narrow economic indicators, not the full range of capabilities.

Option C:
Correct; it contrasts people’s capabilities and freedoms with the income/output focus of economic growth, matching the UNDP human development approach.

Option D:
Incorrect; human development explicitly includes education and health alongside income, so excluding them contradicts the concept.

Statement B is the only wrong statement because the urban heat island effect actually results in higher temperatures in city centres compared to rural surroundings. Statements A, C and D are correct as they reflect well-documented environmental issues and solutions related to urbanisation. Rapid unplanned urbanisation does produce slums and poor sanitation, transport emissions worsen air quality and proper planning can mitigate such impacts. Therefore, the combination that identifies B only as wrong is the correct answer.

Option A:
Option A is incorrect because it treats statement A as wrong, whereas A accurately describes the consequences of unplanned urban growth such as slums, congestion and poor sanitation. These are widely recognised in urban studies and environmental planning. Since A is a correct statement, calling it wrong makes this option invalid.

Option B:
Option B is correct because it singles out statement B, which misrepresents the urban heat island effect by stating that city centres become cooler than rural areas. In reality, built-up surfaces and reduced vegetation make cities warmer, so B is clearly incorrect. As A, C and D are all correct, identifying only B as wrong satisfies the requirement of the question.

Option C:
Option C is incorrect because it claims both A and B are wrong. While B is indeed wrong, A is correct since unplanned urbanisation is strongly associated with slums and inadequate infrastructure. By including a correct statement in the set of wrong statements, this option fails the logical condition of the question.

Option D:
Option D is incorrect because it asserts that both B and C are wrong. C is correct because vehicle and transport-related emissions are major sources of urban air pollution and greenhouse gases. Grouping a correct statement with B in the wrong set makes this combination unacceptable.

Biomass fuels such as firewood,crop residues and dung cakes are commonly burned in traditional chulhas without proper ventilation. This combustion releases smoke and fine particulate matter,leading to serious respiratory and eye problems. The stem specifically refers to traditional chulhas in rural households,which clearly points to biomass fuels. Therefore Option D is correct.

Option A:
LPG burns much more cleanly than biomass and is promoted as a cleaner fuel alternative under various government schemes. While incomplete combustion can still produce some pollutants,it is not the main source of indoor smoke described in the question.

Option B:
Electricity used for cooking through induction or electric stoves does not involve combustion inside the home and therefore produces negligible indoor air pollution. It cannot be the primary cause of smoky indoor environments in rural areas.

Option C:
Solar energy can be used for lighting or cooking through solar cookers,but again does not produce indoor smoke when used properly. It is usually seen as an environmentally friendly option,rather than a pollutant source.

Option D:
Biomass fuels,when burned inefficiently,produce high levels of particulate matter,carbon monoxide and other harmful gases. This makes them a key focus of health and environment programmes in rural settings,matching the stem.

Article 6 of the Paris Agreement provides for two broad mechanisms: bilateral or plurilateral cooperative approaches under 6.2, and a UN-supervised crediting mechanism under 6.4. At COP29, parties worked to finalise rulebooks that clarify accounting, authorisation and reporting, so that carbon trading can support higher ambition and avoid double counting. Agreement on these rules is seen as crucial for building confidence in international carbon markets. It also links trading to sustainable development safeguards. (Drishti IAS)

Option A:
This option is incorrect because there was no decision to abolish all carbon markets; instead, negotiations focused on how to shape them under Article 6. Carbon markets remain a recognised tool, though their design is contested. Saying they were “completely abolished” misrepresents the outcome.

Option B:
Limiting participation to companies and excluding countries would contradict the concept of “cooperative approaches” between parties to the Paris Agreement. In practice, Article 6.2 is about country-to-country transfers backed by robust national accounting. This option therefore mis-states the architecture.

Option C:
Restricting carbon markets only to forestry projects was not the decision; while land-use and forestry are important, Article 6 mechanisms can, in principle, cover multiple sectors. This over-narrow description does not match the breadth of discussions.

Option D:
This option accurately reflects the dual structure of Article 6 and the focus of COP29 decisions on operationalising both 6.2 and 6.4 mechanisms. It captures why the outcome matters for future carbon trading and for linking markets to the Paris goals, making it the correct answer.

Statements A, B and D are correct as they reflect the text and spirit of SDG 11, which emphasises inclusive, safe, resilient, sustainable settlements, improved services and participatory governance. Statement C is incorrect because environmental quality, including air, green spaces and waste, is central to sustainable cities. Statement E is also wrong as SDG 11 applies to cities and human settlements of all sizes. Thus, the combination A, B and D only is correct.

Option A:
Option A is incomplete because it omits D, which highlights participatory planning as a key strategy for implementing SDG 11. Without D, the governance aspect of sustainable cities is not addressed.

Option B:
Option B is incorrect since it includes C along with A and B, thereby accepting the false claim that sustainable cities initiatives ignore environmental concerns. In reality, environmental quality is one of their core pillars.

Option C:
Option C is incorrect as it groups B, D and E and treats E as correct. While B and D are true, E wrongly limits SDG 11 to megacities and excludes smaller towns, which goes against the universal applicability of the SDGs.

Option D:
Option D is correct because it selects the three true statements and excludes C and E, both of which misrepresent the sustainable cities agenda. It captures social, service-related and governance dimensions of SDG 11.

Statement C is the only wrong statement because noise control is not limited to personal protective devices; it also includes engineering controls, planning measures and legal regulations. Statements A, B and D are correct: A highlights health effects, B recognises noise as environmental pollution and D lists valid control strategies. Therefore, the combination that identifies C only as wrong is the correct answer.

Option A:
Option A is correct since it accurately singles out C as the wrong statement and leaves A, B and D recognised as true. It reflects the comprehensive approach to noise management that extends beyond individual protection. Thus it matches the requirement of selecting the wrong statement(s).

Option B:
Option B is incorrect because it treats both A and C as wrong. Statement A correctly describes adverse health impacts of chronic noise exposure, such as hearing loss and stress-related problems. Including a correct statement in the wrong set makes this option invalid.

Option C:
Option C is incorrect as it groups C and D together as wrong statements. While C is indeed wrong, D is correct in giving examples of zoning, silencers and time restrictions that are widely used in noise regulation. This mixture of one true and one false statement cannot be accepted.

Option D:
Option D is incorrect because it sees B and C as wrong. B is a correct statement since noise is widely recognised as environmental pollution affecting well-being. Treating B as wrong undermines standard environmental health knowledge.

The Basel Convention was adopted to control the movement of hazardous wastes across national boundaries and to ensure their environmentally sound management. It arose partly in response to cases of hazardous waste from developed countries being dumped in developing nations. The stem emphasises transboundary movement and disposal,which clearly points to hazardous wastes. Hence Option D is correct.

Option A:
Noise is a form of pollution but is not transported and traded internationally in the way physical wastes are. The Basel Convention does not primarily address noise issues,so Option A is not suitable.

Option B:
Radiation is regulated by other international instruments and agencies concerned with nuclear safety and radioactive materials. While some radioactive wastes are hazardous,the Basel Convention focuses broadly on hazardous wastes as a category rather than just radiation.

Option C:
Electronic messages are intangible and involve information flows rather than physical materials. They are outside the scope of the Basel Convention,which deals with tangible hazardous waste shipments.

Option D:
Wastes under the Basel Convention include industrial residues,obsolete chemicals and other dangerous materials that can harm people and the environment. This accords with the definition implied in the question stem.

Common but differentiated responsibilities (CBDR) acknowledges that all states share responsibility for global environmental protection,but not equally. Developed countries,with higher historical emissions and greater capacities,are expected to take the lead. This reflects an equity oriented approach among nations. The stem asks what concern the principle mainly reflects,which is fairness or equity. Hence Option B is correct.

Option A:
Technology monopoly would mean control of technology by a few actors and is not the normative basis of CBDR. The principle calls for shared but differentiated obligations,not monopolies.

Option B:
Equity in climate policy means recognising differences in historical emissions and capabilities while allocating mitigation and adaptation burdens. CBDR is a concrete expression of this idea,matching the description in the question.

Option C:
Homogeneity assumes countries are similar,which CBDR explicitly rejects. It is based on recognising differences,so Option C contradicts the principle.

Option D:
Isolation is not encouraged by climate agreements,which require cooperation. It has no connection to CBDR,so Option D is inappropriate.

The Brundtland Report gave a concise and influential definition of sustainable development that has been widely adopted in global discourse. It emphasises meeting present needs, especially of the poor, while recognising ecological limits and the rights of future generations. This definition integrates economic, social and environmental dimensions into a single guiding principle. Therefore, the statement in option A directly reflects the core idea of sustainable development as intergenerationally just development.

Option A:
Option A correctly balances current human needs with long-term environmental capacity. It accepts that development is necessary but insists that it must respect ecological limits and future rights. This comprehensive view is exactly what makes the Brundtland definition central in debates on people, development and environment.

Option B:
Option B is incorrect because it explicitly ignores future costs and ecological constraints. Such growth-first thinking can lead to resource depletion, pollution and social exclusion, which contradict sustainable development.

Option C:
Option C is incorrect since focusing only on environmental protection without considering human needs would make development socially unacceptable. Sustainable development seeks harmony between environmental conservation and human welfare, not a one-sided approach.

Option D:
Option D is incorrect because limiting development to industrial expansion neglects social justice and environmental sustainability. Industrial growth may be part of development but cannot represent sustainable development by itself.
