UGC NET Questions (Paper – 1)

The poverty–environment nexus highlights a vicious cycle where poor households rely heavily on nearby land, forests and water for survival. Lacking alternatives, they may overexploit these resources, for example through excessive fuelwood collection or cultivation on steep slopes. Degradation of the resource base then reduces productivity, pushing them into even deeper poverty. This interconnected spiral is a central concern of people-centred environmental policy.

Option A:
Option A is incorrect because scarcity and lack of alternatives often force the poor into unsustainable practices despite low overall consumption.

Option B:
Option B is correct; it clearly expresses how poverty and environmental degradation can reinforce each other, creating a difficult trap to escape.

Option C:
Option C is incorrect as many studies show strong links between environmental quality and livelihood security, especially for resource-dependent communities.

Option D:
Option D is incorrect because the poor are often the most vulnerable to environmental decline, lacking savings and insurance to cushion shocks.

All four statements are correct and describe different aspects of air pollution and its management. PM2.5 and similar pollutants are harmful because they reach deep lung regions and may enter circulation. Vulnerable groups like children and the elderly face higher risks, and epidemiological studies link pollution to respiratory and cardiovascular problems. Air quality management combines regulatory, technological and behavioural measures. Therefore, the combination A, B, C and D is the correct answer.

Option A:
Option A is incorrect because it lists only A and B and omits C and D. While it acknowledges pollutant characteristics and vulnerable groups, it ignores the documented disease links and the multi-pronged strategy for control, so it is incomplete.

Option B:
Option B is incorrect as it includes A, B and C but leaves out D. Without mentioning management strategies such as emission standards and cleaner fuels, the option does not fully represent how societies respond to air pollution.

Option C:
Option C is incorrect since it includes B, C and D but excludes A. Statement A about PM2.5’s ability to penetrate deep into the lungs is fundamental to understanding health effects, so leaving it out makes the set partial.

Option D:
Option D is correct because it recognises that all four statements accurately reflect the science of air pollution and public health as well as key elements of control strategies. It is the only option that includes every true statement.

Kitchen food scraps consist mainly of organic matter that microorganisms can decompose into simpler compounds. This means they are biodegradable and can be converted into compost under appropriate conditions. The stem refers specifically to vegetable peels and leftover food,which fit the category of biodegradable solid waste. Hence Option A is correct.

Option A:
Biodegradable waste decomposes naturally and is suitable for composting/biogas,which fits kitchen scraps.

Option B:
Inert waste does not decompose significantly (e.g.,construction debris),so it does not match food waste.

Option C:
Hazardous waste contains toxic/flammable/corrosive substances requiring special handling; typical kitchen scraps are not hazardous.

Option D:
Radioactive waste comes from nuclear activities and is unrelated to household food waste.

Statements A, C, D and F are correct because they emphasise interconnections among sectors, water dependence of energy production, the value of integrated planning and the cross-sector effects of demand and efficiency measures. Statement B is wrong since irrigation pumps and water conveyance can significantly increase energy use, and E is wrong because SDGs explicitly require integrated approaches across water, energy and food. Thus, the correct combination is A, C, D and F only.

Option A:
Option A is incorrect as it omits F, overlooking how demand management or efficiency in one sector can relieve pressure in the others. Without F, the answer underplays practical levers for improving nexus outcomes.

Option B:
Option B is incorrect because it includes B and excludes F. Accepting B ignores well-known links between irrigation expansion and energy demand, while dropping F removes an important strategy for reducing pressures.

Option C:
Option C is correct as it encompasses all the true statements about linkages, dependencies, planning and efficiency while rejecting B and E, which deny key aspects of the nexus and its relevance to SDGs.

Option D:
Option D is incorrect since it includes B and E, placing two clearly false statements alongside some true ones. It also omits A, ignoring the basic premise of interconnection central to the nexus concept.

Agenda 21 is a comprehensive programme of action covering social,economic and environmental dimensions of sustainable development. It was agreed by governments at the 1992 United Nations Conference on Environment and Development in Rio. The stem mentions a global plan into the twenty first century adopted at the Earth Summit,which clearly identifies Agenda 21. Thus Option D is correct.

Option A:
“Agenda 10” is not a recognised UN global plan adopted at the 1992 Rio Earth Summit,so it does not fit the stem.

Option B:
“Agenda 15” is not the title of the Rio 1992 sustainable development plan of action,so it is incorrect here.

Option C:
“Agenda 17” is not the Rio 1992 plan of action; it does not match the historical document referred to in the question.

Option D:
Agenda 21 is explicitly named for the 21st century and was adopted at the 1992 Earth Summit as a global sustainable development action plan,matching the stem.

Statements A, B and D are correct as they summarise the main stages of treatment and the possibility of safe reuse. Primary and secondary treatments remove solids and organic load, and with sufficient treatment, wastewater can be used for irrigation under guidelines. Statement C is incorrect because untreated discharges degrade water quality, harm aquatic life and pose health risks. Thus, the combination A, B and D only is correct.

Option A:
Option A is correct because it includes all three true statements and excludes C, which underestimates the impacts of untreated discharge. It reflects the technical and reuse aspects expected in environmental management questions.

Option B:
Option B is incomplete as it lists only A and B and leaves out D. While it covers process stages, it does not acknowledge the important practice of safe reuse, which is increasingly promoted.

Option C:
Option C is incorrect since it accepts C along with B and D. Including C implies that untreated wastewater has no serious impacts, which contradicts well-established water pollution studies.

Option D:
Option D is incorrect because it combines A with C and D. Although A and D are true, accepting C as correct makes the option conceptually wrong.

Statements A, B and D accurately describe constructive student participation in governance. Students can be part of councils and committees, systematic feedback is a recognised input to programme review, and such participation nurtures democratic values and shared responsibility. Statement C is false because appointment of Vice-Chancellors follows statutory procedures and is not decided by direct student elections. Statements E and F are false because faculty and staff remain essential governance participants and student voices are in fact relevant for campus life decisions.

Option A:
Option A is incorrect because it omits statement D and therefore fails to highlight the important effect of student participation in building a democratic and participatory institutional culture.

Option B:
Option B is incorrect because it includes C, which wrongly states that students alone elect the Vice-Chancellor, misrepresenting the statutory procedures for such appointments.

Option C:
Option C is incorrect because it treats C as correct and omits D, thereby giving an inaccurate and incomplete picture of governance structures and their purposes.

Option D:
Option D is correct since it combines A, B and D, the three true statements, while excluding C, E and F, which either exaggerate student powers or dismiss the value of student voices and shared governance.

Statements A, B, D and E are correct since they reflect definitions of mitigation/adaptation, identify key mitigation strategies and emphasise integrated policies for sustainable development. Statement C is incorrect because sea walls and cyclone shelters are adaptation measures. Statement F is incorrect as climate change is linked with changes in extreme weather patterns. Thus, the combination A, B, D and E only is correct.

Option A:
Option A is incomplete because it omits E, thereby ignoring the importance of integrating mitigation and adaptation for sustainable development.

Option B:
Option B is incorrect since it includes F, which wrongly claims there is no link between climate change and extreme events.

Option C:
Option C is correct as it brings together conceptual and strategic aspects and excludes misclassified examples and denial of extreme-event linkages.

Option D:
Option D is incorrect because it includes F and omits A, denying an established link while losing the basic definition of mitigation.

PM-PRANAM is designed to address the environmental and fiscal costs of excessive fertiliser use. States that successfully reduce consumption relative to a baseline can receive a portion of the resulting subsidy savings as grants. These funds can support balanced nutrient management, including organic and bio-fertilisers and capacity building for farmers. The scheme therefore links environmental outcomes with cooperative fiscal incentives.

Option A:
This option is incorrect because the scheme seeks to moderate fertiliser use, not increase it indiscriminately. Raising subsidies without conditions would worsen nutrient imbalances.

Option B:
This option correctly explains how the scheme rewards states for cutting chemical fertiliser use and reinvesting savings in sustainable alternatives.

Option C:
The scheme does not ban organic manures; it promotes them as part of balanced nutrient strategies. Therefore this option contradicts policy intent.

Option D:
PM-PRANAM is unrelated to crop-residue burning; in fact, sustainable agriculture initiatives generally discourage such burning due to air-pollution impacts.

Crossing the 50% non-fossil capacity mark well before 2030 means that one of India’s key NDC targets has effectively been met early. This reflects rapid growth of solar, wind, hydro and nuclear installations alongside continuing demand growth. It strengthens India’s position in climate negotiations by showing that a large developing country can expand modern energy access while moving its power mix towards cleaner sources.

Option A:
This option is incorrect because continued growth of renewables is still needed to meet rising demand and to reduce dependence on fossil fuels in generation.

Option B:
This option correctly interprets the milestone as an early achievement of a Paris-related goal and as evidence of an accelerated energy transition.

Option C:
Coal still provides a substantial share of electricity generation even if its share in installed capacity is falling, so this statement is factually wrong.

Option D:
There is no legal ban on fossil fuels in all sectors; the transition is gradual and sector-specific.

Statements A, B and D are correct as they reflect established public health knowledge about contaminated water, vulnerability of children and benefits of integrated WASH programmes. Statement C is incorrect because handwashing with soap at critical times is one of the most effective measures to prevent diarrhoeal and related diseases. Therefore, the combination A, B and D only is the correct answer.

Option A:
Option A is incorrect because it excludes D, which correctly emphasises the value of integrated WASH interventions. Without D, the answer does not show how combined strategies reduce disease burden.

Option B:
Option B is incorrect since it includes C, which wrongly downplays the effectiveness of handwashing. Including this false statement makes the combination unacceptable.

Option C:
Option C is incorrect as it groups B, C and D and accepts C as true. While B and D are correct, C is not, so the option mixes true and false statements.

Option D:
Option D is correct because it recognises that unsafe water and sanitation particularly harm children and that integrated WASH programmes can substantially lower disease. It also correctly rejects statement C.

Environmental racism refers to patterns in which racial or ethnic minority communities are systematically targeted for undesirable land uses like hazardous waste sites,or receive fewer environmental benefits. It highlights how racism can be embedded in environmental decision making. The stem explicitly mentions marginalised communities disproportionately exposed to hazards,which captures this concept. Therefore Option C is correct.

Option A:
Environmental efficiency focuses on reducing pollution per unit output and does not address unequal exposure burdens.

Option B:
Ecological modernisation focuses on aligning growth and environmental protection via innovation and reform; it does not inherently explain disproportionate hazard siting.

Option C:
Environmental racism directly names the disproportionate exposure of marginalised groups to hazards due to systemic inequities,matching the stem.

Option D:
Demographic bonus relates to age structure and labour force,not environmental hazard burdens.

The 3R principle is a hierarchy that guides waste management towards sustainability. The most preferred option is to reduce waste generation at source, followed by reusing products to extend their life, and finally recycling materials so they can be processed into new products. This order minimises resource use and environmental impact. Hence, the correct sequence is Reduce, Reuse, Recycle, as given in option C.

Option A:
Option A is incorrect because it starts with reuse and places reduction later. While reuse is beneficial, preventing waste generation in the first place through reduction is considered even more desirable.

Option B:
Option B is incorrect since it begins with recycling, which, although useful, still requires energy and processing. Waste reduction and reuse are higher priorities as they avoid or delay waste creation.

Option C:
Option C is correct because it follows the established waste management hierarchy: first reduce consumption and waste, then reuse products, and finally recycle materials. This sequence aligns with environmental guidelines and UGC NET content.

Option D:
Option D is incorrect as it reverses the preferred order and again starts with recycling. Such a sequence does not reflect the principle of preventing and minimising waste before managing it.

Statements B, C and D are correct as they stress local participation, multi-level perspectives and the need for clear roles and coordination. Local actors bring contextual knowledge, multi-level governance recognises the nested nature of environmental issues and clear institutional arrangements prevent overlap and conflict. Statements A and E are incorrect because decentralisation without capacity and accountability can fail, and public access to environmental information is a key ingredient of transparency and good governance. Thus, the combination B, C and D only is the correct answer.

Option A:
Option A is incorrect since it omits D, which rightly emphasises the importance of defined roles and coordination mechanisms among institutions for effective governance. Without D, the combination does not fully reflect the institutional dimension.

Option B:
Option B is correct because it groups together the three elements widely recognised in governance literature and excludes the simplistic and dismissive statements A and E. It acknowledges that decentralisation must be supported by capacity and information to work well.

Option C:
Option C is incorrect because it includes A along with B, C and D. Statement A assumes decentralisation is always beneficial regardless of context, which contradicts evidence that weak local capacity or capture can lead to poor outcomes.

Option D:
Option D is incorrect as it adds statement E, which denies the relevance of access to information for governance quality. Transparency and information access are central to accountability, so including E undermines the combination.

Option E is incorrect because it contains A, C and D, and A is false for the reasons noted. Even though C and D are correct, the inclusion of A means this set cannot be taken as representing only correct statements.

Option F is incorrect since it groups A, D and E, of which only D is correct. Both A and E misrepresent conditions needed for effective environmental governance, so the combination is largely inaccurate.

Ecological succession describes the gradual change in species composition and community structure over time after disturbances. Human actions such as clearing forests, burning grasslands or building infrastructure can interrupt or restart this process by removing existing vegetation and altering soil conditions. Frequent or intense disturbances may prevent ecosystems from reaching later successional stages, or they may send succession along a different trajectory altogether.

Option A:
Option A is incorrect because it suggests humans alter succession by never disturbing ecosystems, which is unrealistic and does not describe the main way people influence successional dynamics.

Option B:
Option B is incorrect because humans cannot and do not completely stop all natural disturbances such as fires, storms and grazing everywhere.

Option C:
Option C is correct because repeated disturbances like deforestation, overgrazing and construction repeatedly push ecosystems back to earlier successional stages or redirect them into novel states.

Option D:
Option D is incorrect because ecological theory recognises multiple potential stable states and ongoing dynamics; it is unrealistic to expect all ecosystems to quickly reach and remain in a single climax state, especially under strong human influence.
