UGC NET Questions (Paper – 1)

Statements A, B and D are correct because climate agreements address mitigation and adaptation, most treaties require reporting and review and domestic measures are needed to give effect to international commitments. Statement C is incorrect since non-state actors such as NGOs, businesses and local bodies play important roles in implementation, monitoring and advocacy. Global environmental governance is multi-actor and multi-level. Hence, the combination A, B and D only is correct.

Option A:
Option A is incomplete as it lists only A and B and omits D. Without acknowledging the need for national laws and institutions, it does not fully explain how agreements are implemented domestically.

Option B:
Option B is incorrect because it includes only B and D and leaves out A, which is a central statement about the objectives of climate agreements. Ignoring A makes the description of agreements less comprehensive.

Option C:
Option C is correct since it includes all three true statements and excludes C, which wrongly denies any role for non-state actors. It reflects the complex nature of contemporary environmental governance.

Option D:
Option D is incorrect because it accepts C along with A and D. Although A and D are true, endorsing C would ignore the important contributions of civil society and other actors to treaty implementation.

A youth bulge refers to a situation where a large share of the population is in younger age groups. This pattern appears as a very wide base in the population pyramid. The stem explicitly describes such a broad base of children and adolescents,so youth bulge is the correct term. It has important implications for employment and social stability.

Option A:
Demographic dividend is the potential economic benefit that can arise when the working age group is large relative to dependants. While a youth bulge can precede a dividend,it is not the same phenomenon described in the question.

Option B:
An ageing population is dominated by older persons,rather than children and youth. Its age pyramid tends to have a narrower base and wider top,which is different from the broad base depicted in the stem.

Option C:
A balanced structure would imply relatively even proportions across age groups,not a heavy concentration at the bottom. Therefore it does not match the situation where children and adolescents dominate the population.

Option D:
Youth bulges can create opportunities if education and jobs are available but also pose risks if large cohorts face unemployment. This dual potential is why the concept is frequently analysed in development and security studies.

Nuclear power plants produce relatively low direct carbon emissions during normal operation. However, they generate radioactive wastes that remain hazardous for very long periods. Ensuring safe storage, transport and ultimate disposal of this waste poses technical, financial and institutional challenges. Thus, the long-term management of radioactive waste is widely recognised as a major environmental and health concern linked to nuclear power generation.

Option A:
Option A is incorrect because nuclear plants emit far less carbon dioxide than fossil fuel plants per unit of energy produced. While there are emissions in construction and fuel processing, large direct CO₂ release is not their defining environmental problem.

Option B:
Option B is incorrect since sulphur dioxide and soot are characteristic emissions from coal and oil combustion. Properly operated nuclear reactors do not release these pollutants in stack gases.

Option C:
Option C is incorrect because although nuclear plants require significant cooling water, they are usually sited and managed to avoid completely depleting groundwater resources. Water use is an issue but not the unique long-term hazard compared with radioactive waste.

Option D:
Option D is correct as it points to the persistent hazard of long-lived radionuclides. Safe containment must be maintained over time scales far exceeding normal infrastructure lifetimes, making this a central issue in debates over nuclear energy.

Environmental ethics expands the circle of moral concern beyond present human interests. It argues that future generations, other species and ecosystems have intrinsic or at least significant moral value. Development choices should therefore respect ecological integrity and intergenerational justice rather than focusing solely on short-term human gains. The statement that future generations and non-human species deserve moral consideration captures this ethical perspective, making Option B correct.

Option A:
Option A is incorrect because treating nature as valuable only for immediate human use leads to unsustainable exploitation and ignores intrinsic or long-term values. This purely instrumental view is questioned by most environmental ethicists.

Option B:
Option B is correct since it acknowledges that development decisions should weigh impacts on those who cannot speak for themselves, including future people and non-human life. This outlook underpins principles like intergenerational equity and the precautionary approach.

Option C:
Option C is incorrect as it prioritises only current economic profits. Such a narrow focus neglects the rights of future generations, planetary boundaries and non-economic values like cultural and spiritual ties to nature.

Option D:
Option D is incorrect because environmental problems inevitably raise questions about justice, rights and responsibilities. Technical solutions must be guided by ethical frameworks, not separated from them.

Statements A, B, D and E are correct and together describe the environmental risks and governance needs of tourism. Mass tourism can damage ecosystems and cultures, ecotourism seeks to reduce harm, carrying capacity helps frame limits and community involvement can improve outcomes. C is wrong because tourism can strain water resources and create pollution, and F is wrong since educating tourists supports responsible behaviour. Therefore, A, B, D and E only is the correct set.

Option A:
Option A is correct as it gathers all the true statements and excludes C and F, which underestimate tourism’s potential impacts and the role of education. It reflects principles of sustainable and community-based tourism.

Option B:
Option B is incorrect because it omits E, ignoring the importance of community participation and benefit-sharing in reducing conflict and ensuring local support. Without E, the governance dimension is incomplete.

Option C:
Option C is incorrect as it includes F and omits A. Accepting F denies the usefulness of environmental education for visitors, and dropping A ignores the well-documented negative impacts of unregulated mass tourism.

Option D:
Option D is incorrect since it includes C, which falsely claims tourism only has positive water effects, and still omits B, which is central to the concept of ecotourism. This combination mixes correct and incorrect elements.

Environmental ethics is a branch of applied ethics that focuses on how humans ought to relate morally to the environment and non-human beings. It questions whether nature has intrinsic value beyond its utility to humans. It also debates anthropocentric, biocentric and ecocentric viewpoints regarding environmental decision-making. Therefore, its central concern is the moral relationship between human beings and the natural world, which is captured in option C.

Option A:
Option A is incorrect because assessing economic value belongs more to environmental economics than environmental ethics. While ethics may question how we value nature, the central focus is not economic valuation but moral responsibility.

Option B:
Option B is incorrect as legal analysis belongs to environmental law. Ethics can influence law, but the study of statutes and regulations is not itself the main focus of environmental ethics.

Option C:
Option C is correct since it directly refers to the moral relationship between humans and nature. This includes questions about duties to animals, ecosystems and future generations, which lie at the heart of environmental ethics.

Option D:
Option D is incorrect because developing technologies for resource extraction is a technical and engineering activity. Environmental ethics may evaluate whether such technologies should be used, but it does not focus on their development.

Higher ethanol blending in petrol can cut lifecycle emissions compared to pure fossil gasoline when produced sustainably. It reduces the quantity of imported crude oil needed for transport fuels, improving energy security. At the same time, it creates additional demand for crops such as sugarcane and maize, potentially raising rural incomes if supported by responsible water and land management.

Option A:
This option is incorrect because blending ethanol substitutes a part of imported fossil fuel, thereby lowering, not increasing, crude oil dependence.

Option B:
This option correctly summarises the multiple co-benefits of E20 in climate, energy and rural development terms, while implicitly recognising sustainability conditions.

Option C:
Regular maintenance is still required for vehicles; fuel type alone does not remove the need for upkeep, so this statement is misleading.

Option D:
Public transport investments remain essential for reducing congestion and emissions; E20 is a complementary measure, not a substitute.

Environmental responsibility under CSR expects companies to go beyond legal compliance and proactively reduce their ecological footprint. This can include improving energy and resource efficiency, controlling emissions, managing waste responsibly and participating in restoration of degraded ecosystems around their operations. Such actions align business goals with community and environmental well-being, strengthening social licence to operate.

Option A:
Option A is incorrect because omitting environmental information from reports hides important impacts and does not reflect transparent or responsible corporate behaviour.

Option B:
Option B is correct since it lists concrete steps that lower environmental harm and support local ecological recovery, which are central to CSR’s environmental dimension.

Option C:
Option C is incorrect as ignoring environmental consequences for profit contradicts both CSR principles and many modern regulatory expectations.

Option D:
Option D is incorrect because shifting polluting units to lax regions amounts to "pollution havens" and does not reduce overall environmental damage; it undermines global sustainability.

Statement B is the only wrong statement because many countries require Environmental Impact Assessment for major transportation projects to examine potential impacts and mitigation options. Statements A, C and D are correct: highways can fragment habitats and cause road kills, consultation surfaces local concerns and properly designed structures can help wildlife cross roads safely. Hence, identifying B only as wrong is the correct response.

Option A:
Option A is incorrect because it considers both A and B as wrong, even though statement A correctly identifies habitat fragmentation and wildlife mortality as established impacts of highway construction. Grouping a correct statement with the wrong one is not logically consistent with the question’s demand.

Option B:
Option B is incorrect as it marks B and C as wrong. While B is false, C is correct since public consultation is a widely recognised part of participatory environmental planning and is required in many EIA processes. Treating C as wrong contradicts good governance principles.

Option C:
Option C is incorrect because it labels B and D as wrong together. Statement D is valid, as wildlife crossings like culverts and underpasses are an important mitigation measure in road ecology. Including D among wrong statements makes this option unacceptable.

Option D:
Option D is correct since it isolates B, the only incorrect statement, and implicitly recognises A, C and D as correct. It reflects current practice where EIAs, public participation and engineering design for wildlife are key elements in managing transport-related environmental impacts.

Statements A, B and D are correct because they highlight curriculum integration, experiential activities and community involvement, all of which are emphasised in environmental education policies. Statement C is incorrect since restricting learning to textbooks and exams undermines the attitudinal and behavioural goals of environmental education. Therefore, the combination A, B and D only is correct.

Option A:
Option A is incomplete as it includes only A and B and omits D. Without recognising the role of parents and communities, the answer leaves out an important avenue for reinforcing learning beyond school.

Option B:
Option B is correct because it includes all three accurate statements and excludes C, which misrepresents effective environmental education practice. It reflects the holistic, participatory and experiential approach expected at school level.

Option C:
Option C is incorrect since it accepts C along with B and D. Including C would endorse a narrow focus on textbooks and exams, contrary to the objectives of environmental education.

Option D:
Option D is incorrect because it groups A with C and D and treats C as correct. While A and D are valid, including C makes the overall combination inconsistent with accepted approaches.

Statements A, B, D and E are correct as they describe contamination pathways, the importance of safe sludge and wastewater management, the effectiveness of handwashing and the role of school facilities, especially for girls. Statement C is wrong because toilets without use, cleaning and maintenance do not remove disease risks, and F is wrong since poor solid waste management contributes to vector breeding and environmental contamination. Therefore, the correct combination includes A, B, D and E and excludes C and F.

Option A:
Option A is correct since it brings together all key links between sanitation, health and education outcomes, while leaving out statements that oversimplify solutions or deny environmental health connections. It reflects the integrated WASH perspective promoted in this unit.

Option B:
Option B is incorrect because it omits E and fails to recognise how school facilities affect attendance and dignity. Without E, the answer underplays the gendered and educational dimensions of sanitation.

Option C:
Option C is incorrect as it includes C, which wrongly claims that infrastructure alone guarantees disease elimination. Including C ignores the importance of behaviour change, operations and maintenance for sustained health gains.

Option D:
Option D is incorrect because it accepts F, which denies links between solid waste and environmental health, and excludes A. This combination both removes a fundamental contamination pathway and accepts a false statement.

A gender perspective examines how environmental issues affect women,men and other gender groups differently and seeks to address inequalities. Using gender disaggregated indicators is a direct application of this perspective. The stem mentions such data use,so “gender” perspective is the correct term. Therefore Option A is appropriate.

Option A:
Gender analysis improves the effectiveness and fairness of environment projects by ensuring that benefits and burdens are not skewed. This aligns directly with the intention described in the question.

Option B:
A purely technical perspective may focus on engineering or biophysical aspects without considering social differences. It would miss the gender dimension identified in the stem.

Option C:
A market only perspective gives priority to prices and profits and may overlook equity concerns,including gender inequalities. Thus Option C does not match the question.

Option D:
Military perspectives relate to security strategy and defence,which are not the focus when integrating gender indicators into environmental planning,so Option D is incorrect.

Environmental education seeks to build a broad base of understanding about ecological processes and human impacts. It encourages positive attitudes and values towards nature and equips learners with practical skills to analyse issues, make informed decisions and take action. By empowering people at different levels of society, it supports the transition towards more sustainable patterns of living and governance.

Option A:
Option A is incorrect because mere memorisation of treaty names without context or critical engagement does not lead to meaningful environmental responsibility or action.

Option B:
Option B is correct as it integrates awareness, knowledge, attitudes and skills aimed at real problem solving and participation, which reflects widely accepted objectives of environmental education.

Option C:
Option C is incorrect since restricting education to a narrow group of professionals contradicts the principle that everyone affects and is affected by environmental conditions.

Option D:
Option D is incorrect because environmental education encourages critical thinking about development projects and their environmental consequences, not blind acceptance.

Statements C and D are wrong because they misrepresent both environmental ethics and environmental education. Environmental ethics generally recognises intrinsic value in non-human nature, not just human interests, and therefore C is incorrect. Environmental education is meant for all learners to foster environmental responsibility, so restricting it only to science students as in D is also wrong. Statements A and B correctly describe the scope of environmental ethics and goals of environmental education, so the correct set of wrong statements is C and D only.

Option A:
Option A is incorrect because it singles out C as the only wrong statement and treats D as acceptable. While C is indeed wrong, D is also incorrect because environmental education is intended to be interdisciplinary and open to all learners, not restricted to science students. Excluding D from the wrong set makes this combination incomplete.

Option B:
Option B is correct because it identifies both C and D as misrepresentations of the concepts involved. Environmental ethics goes beyond anthropocentric interests, and environmental education is not discipline-bound. By excluding A and B, which are correct, this option satisfies the requirement of selecting all wrong statements.

Option C:
Option C is incorrect because it claims that A, C and D are wrong. Statement A accurately defines environmental ethics as exploring the moral relationship between humans and nature and is widely accepted in philosophy and environmental studies. Including a correct statement in the wrong set makes this option logically flawed.

Option D:
Option D is incorrect because it groups B, C and D as wrong statements. Statement B is correct since environmental education indeed aims at developing knowledge, attitudes and skills to address environmental issues. Treating B as wrong along with C and D contradicts the established objectives of environmental education.

A sanitary landfill is engineered to reduce the environmental problems associated with simple open dumping. It typically includes liners to prevent leachate from contaminating groundwater, systems to collect and treat leachate and gas, and daily soil cover to reduce odour, pests and wind-blown litter. Waste is compacted to optimise space and stability. Thus, the description in Option B of controlled placement with lining, compaction and cover expresses the essential features of a sanitary landfill.

Option A:
Option A is incorrect because open dumping lacks controls on leachate, gas and vectors, leading to serious health and environmental risks. Such dumps are the opposite of sanitary landfills.

Option B:
Option B is correct as it highlights the design elements that distinguish sanitary landfills from crude dumping grounds. Properly engineered landfills aim to isolate waste from the environment as it decomposes.

Option C:
Option C is incorrect as burning waste in the open emits toxic smoke and particulate matter. Open burning is discouraged in modern waste management and is not a feature of sanitary landfills.

Option D:
Option D is incorrect because discharging untreated liquid waste into rivers violates basic pollution control principles. Landfills are meant to safely contain and treat pollutants, not release them directly into water bodies.
