UGC NET Questions (Paper – 1)

The Montreal Protocol on Substances that Deplete the Ozone Layer was agreed in 1987 and has successfully reduced the production of chlorofluorocarbons and related chemicals. It is widely regarded as one of the most effective environmental treaties. The stem mentions phasing out ozone depleting substances,which is the core objective of the Montreal Protocol. Therefore Option A is the correct answer.

Option A:
Montreal was chosen as the name because the original agreement was adopted in that city. The Protocol’s controls have been strengthened through subsequent amendments,supporting recovery of the ozone layer.

Option B:
The Kyoto Protocol is a climate agreement focusing on greenhouse gas emissions and does not primarily address ozone depleting substances,so it is not the treaty referred to in the stem.

Option C:
“Geneva Protocol” is not the main global agreement for phasing out ozone depleting substances. The well known treaty for this purpose is the Montreal Protocol.

Option D:
The Nagoya Protocol relates to biodiversity access and benefit sharing under the Convention on Biological Diversity,not to ozone depleting substances.

Logistic growth describes a population pattern where growth is initially rapid but slows as resources become limiting. The curve eventually levels off at the carrying capacity,forming an S shaped pattern. This model reflects the influence of environmental resistance on population expansion. Thus the description in the question corresponds to logistic growth.

Option A:
Linear growth implies a constant increase by the same absolute amount over equal time intervals. It does not show slowing down as the population approaches a limit. Therefore it does not match the S shaped pattern described in the stem.

Option B:
Logistic growth incorporates both the initial exponential phase and the later plateau at carrying capacity. Environmental constraints such as food shortages or space limitation cause the slowdown. This behaviour makes logistic the correct term for the question.

Option C:
Exponential growth describes a J shaped curve where the population increases by a constant proportion without resource limits. It does not stabilise at a carrying capacity within the model. Hence it is inconsistent with the description given.

Option D:
Cyclical growth refers to populations that fluctuate regularly over time due to seasonal factors or predator prey dynamics. While it involves variation,it is not characterised by a single plateau at carrying capacity. Therefore it is not the best answer here.

The MPI is based on the idea that poverty is multidimensional, capturing deprivations in health, education and living standards rather than relying only on income-based measures.

Option A:
Incorrect, because income alone cannot capture deprivations in nutrition, schooling or basic amenities that the MPI explicitly includes.

Option B:
Correct, since it states that poverty must be assessed across several key dimensions of human life, which is exactly how the MPI is constructed.

Option C:
Incorrect, as unemployment refers only to labour market status and misses many poor people who work but remain deprived.

Option D:
Incorrect, because focusing only on land ownership ignores urban poverty and other non-land-based forms of deprivation.

The Government of India notified a ban on a set of 19 identified single-use plastic items from 1 July 2022. These items were chosen because they typically have low utility but a high tendency to become litter, such as earbuds with plastic sticks, certain cutlery and decorative thermocol. The approach aims to eliminate the most problematic plastics while allowing time to improve design and regulation of other products. This selective ban is part of a broader strategy under the Plastic Waste Management Rules.

Option A:
This option correctly reflects the targeted nature of the 2022 ban, which focuses on low-utility, high-litter items. It aligns with official notifications and the list of prohibited products. The focus is on reducing visible litter and environmental harm without disrupting essential uses.

Option B:
This option is incorrect because the ban does not cover all forms of plastic; medical and some other essential uses are excluded. A complete ban would be impractical and was not notified.

Option C:
Plastic carry bags were subject to separate rules that increased minimum thickness requirements rather than banning all such bags above 120 microns. Therefore, this option confuses regulation with prohibition.

Option D:
The ban applies domestically and is not restricted to export-oriented units. In fact, export packaging may follow different rules, whereas the notified items are prohibited within the country’s regular markets and use contexts.

Point source pollution originates from a single identifiable source such as a pipe,outfall or chimney. The stem describes effluent entering a river from a specific pipe,which fits this definition exactly. Therefore it is correctly classified as point source pollution.

Option A:
Non point source pollution arises from many dispersed sources like agricultural runoff or urban stormwater. It is difficult to trace to a single discharge point. Since the question mentions one pipe,non point is not accurate.

Option B:
Point sources are typically easier to monitor and regulate because their location and discharge characteristics can be precisely identified. Industrial pipes and sewage outlets are classic examples. This explanation matches the scenario described in the stem.

Option C:
Diffuse pollution is another term used for non point pollution,emphasising its widespread and scattered nature. It does not apply when a single clearly defined outlet is involved. Hence it is not the correct answer here.

Option D:
Natural sources such as soil erosion or volcanic activity can introduce materials into water bodies,but the stem specifically mentions industrial effluent. Therefore natural is not an appropriate classification.

Sustainable human development combines the human development emphasis on expanding capabilities with the sustainability concern for protecting environmental resources. It aims to improve well being for current generations without undermining opportunities for those yet to come. This approach recognises that long term human progress depends on ecological integrity. Hence the description in the question matches sustainable human development.

Option A:
Structural adjustment refers to policy packages involving liberalisation,privatisation and deregulation,typically promoted to stabilise economies. These programmes often focus on macroeconomic objectives rather than long term human and environmental well being. Therefore they do not fit the concept in the stem.

Option B:
Sustainable human development explicitly links the capability approach with intergenerational justice. It encourages development paths that are socially inclusive and ecologically sound. Because the question stresses both present and future options,this term is the correct answer.

Option C:
Economic liberalisation denotes reducing government intervention in markets and opening economies to global competition. While it can influence growth,it is not inherently centred on sustaining human capabilities over time. Thus it is not the best term here.

Option D:
Export led growth strategies prioritise expanding exports as the main engine of economic expansion. They may or may not be environmentally or socially sustainable. Consequently,they do not capture the comprehensive balance highlighted in the question.

Statements A, B, C and E are correct because they reflect the potential strengths and requirements of decentralised governance. Bringing decisions closer to communities, using local knowledge, building capacity and coordinating across levels can all improve environmental management. D is wrong since participation of marginalised groups does not happen automatically, and F is wrong because accountability mechanisms strongly influence local outcomes. Hence, A, B, C and E only is the correct combination.

Option A:
Option A is incorrect as it omits E, failing to recognise the importance of coordination when environmental issues cross local boundaries, such as river basins or airsheds. Without E, the multi-level governance dimension is missing.

Option B:
Option B is incorrect because it includes D, which wrongly assumes that decentralisation by itself guarantees inclusive participation. In practice, specific measures are needed to involve marginalised groups, so accepting D misrepresents reality.

Option C:
Option C is incorrect since it brings together B, C, E and F and treats F as if accountability were irrelevant. In fact, accountability is vital for ensuring that local authorities act in the public interest, so this option mixes correct and incorrect elements.

Option D:
Option D is correct because it selects all the true statements and excludes D and F, which overstate automatic inclusion and downplay accountability. It provides a balanced picture of what makes decentralised environmental governance effective.

The IPAT identity expresses environmental Impact (I) as the product of Population (P), Affluence (A) and Technology (T). It suggests that impact grows with more people,higher consumption per person and technologies with higher environmental intensity. Therefore the correct mathematical form is P × A × T.

Option A:
A sum such as P + A + T would not capture the multiplicative interactions emphasised in the IPAT framework, where increases in any factor can scale total impact. Hence it does not match the established relationship.

Option B:
The product P × A × T highlights how even modest growth in each factor can combine to produce large changes in environmental impact. This multiplicative understanding aligns precisely with the way the identity is presented in the literature and described in the question.

Option C:
A subtraction expression like P – A – T would be conceptually meaningless in this context, as it could imply negative impacts for certain values and ignores the reinforcing nature of the drivers.

Option D:
A division form P ÷ A ÷ T similarly fails to represent growth in impact with increasing consumption and technological intensity. It is not how the identity is formulated,so it is not appropriate for the blank.

Statements A, B and D are correct as they summarise the core elements of the sustainable livelihoods framework: focus on assets and vulnerability, recognition of multiple strategies and emphasis on participation. Statement C is incorrect because environmental sustainability is explicitly considered in many applications of the framework. Therefore, the combination including A, B and D, and excluding C, is the correct answer.

Option A:
Option A is incorrect since it omits D, which underlines the participatory nature of the approach. Without D, the description lacks an essential principle related to ownership and empowerment.

Option B:
Option B is incorrect because it includes C along with A and B. C wrongly suggests that environmental concerns are ignored, which contradicts the integrative perspective of sustainable livelihoods.

Option C:
Option C is incorrect as it groups B, C and D and thereby accepts C as true while excluding A. This skips the central notion of assets and vulnerability and introduces an incorrect claim about environmental neglect.

Option D:
Option D is correct because it combines all the true statements and discards C, the false one. It reflects how the sustainable livelihoods approach brings together environmental, economic and social considerations through participatory analysis.

The UNFCCC sets the broad goal for international efforts to address climate change. Its objective is to stabilise greenhouse gas concentrations in the atmosphere at a level that avoids dangerous anthropogenic interference with the climate system. This implies achieving a balance where emissions and removals are compatible with environmental and socio-economic resilience. Therefore, the statement about stabilisation at a non-dangerous level correctly reflects the convention’s primary aim.

Option A:
Option A is incorrect because the convention does not demand complete elimination of fossil fuels within a short time frame. Instead, it calls for gradual, cooperative efforts to limit and reduce emissions.

Option B:
Option B is correct as it summarises the key wording of the convention’s objective. It highlights both the need to control atmospheric concentrations and the idea of preventing dangerous, rather than all, human influences on climate.

Option C:
Option C is incorrect since immediate equal per capita emissions are not mandated. While equity is an important principle, operational commitments vary by country and evolve over time.

Option D:
Option D is incorrect because the UNFCCC does not explicitly ban trade in oil and coal. It focuses on emission control, adaptation and financial support mechanisms rather than on direct trade prohibitions.

Statements A, B, C and E are correct because female education influences fertility, education builds environmental awareness, integrated curricula illuminate population–resource linkages and lifelong learning helps people adjust to changing environmental and economic conditions. D is wrong, since education clearly shapes demographic behaviour and environmental choices, and F is wrong because literacy and numeracy underpin informed participation. Thus, the correct combination includes A, B, C and E and excludes D and F.

Option A:
Option A is incorrect because it omits E, thereby ignoring how learning beyond formal schooling contributes to adaptation in a changing environment and labour market. Without E, the picture of education’s role remains incomplete.

Option B:
Option B is incorrect as it accepts D, which denies education’s influence on demographic and environmental outcomes. Including D runs counter to a large body of demographic and environmental education research.

Option C:
Option C is correct since it gathers the four statements that reflect accepted linkages between education, population and environment while rejecting the two that minimise or misrepresent education’s role. It captures both formal and lifelong learning dimensions.

Option D:
Option D is incorrect because it accepts F and omits A. F wrongly claims that basic skills are irrelevant for decision-making, while excluding A ignores one of the most robust findings about female education and fertility.

Statements A, B and D are correct because they describe the nature of e-waste, risks of informal recycling and goals of proper e-waste management. E-waste is a hazardous waste stream due to heavy metals and persistent organic pollutants in discarded electronics. Informal recycling with open burning or acid leaching exposes workers and the environment to toxics. EPR and related policies aim to promote organised collection, safe recycling and sound disposal. Statement C is incorrect because EPR places responsibility primarily on producers, often shared with other actors, not only on consumers.

Option A:
Option A is incorrect because it omits statement D, which is also true. While A and B correctly describe what e-waste is and why informal recycling is risky, leaving out D ignores the role of policy frameworks in promoting safe collection and recycling. Therefore, this option lists only part of the full set of correct statements.

Option B:
Option B is correct because it includes exactly those statements that accurately represent e-waste management: the hazardous nature of e-waste, the dangers of informal recycling and the importance of organised systems and policies. It also excludes statement C, which wrongly assigns responsibility only to consumers. Hence this option reflects the complete and accurate combination.

Option C:
Option C is incorrect because it treats B and C as the only correct statements. Although B is true, C misinterprets EPR by ignoring producer responsibility and the shared but differentiated roles of other stakeholders. The exclusion of A and D further weakens this option.

Option D:
Option D is incorrect as it includes all four statements and thereby accepts C as correct. Since C incorrectly defines EPR, any combination that retains it cannot represent the correct set of statements. This option also fails to distinguish between accurate and inaccurate descriptions of responsibility.

Statements A, B, C, D and F are correct on taxes, subsidies, permits, policy mixes and valuation. Statement E is wrong because economic instruments are intended to reduce pollution when designed well. Therefore A, B, C, D and F only is correct.

Option A:
Option A is incomplete because it omits F.

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

Option C:
Option C is incorrect because it includes E (false).

Option D:
Option D is incorrect because it includes E (false) and omits C.

The IPAT identity summarises environmental impact as I = P × A × T,where P is population,A is affluence or consumption per person and T is the environmental impact per unit of consumption determined by technology. The stem asks for the T term in this product,which is technology. Therefore Option D correctly completes the identity. It highlights that cleaner technologies can reduce impact even when population and affluence grow.

Option A:
Trade influences how impacts are distributed between countries but is not one of the three core factors in the IPAT formulation. While trade patterns matter,they appear indirectly through affluence and technology,so trade is not the right answer.

Option B:
Territory refers to land area or jurisdiction and does not capture the environmental intensity of production and consumption processes. IPAT focuses on population,affluence and technology as primary drivers,not territory.

Option C:
Transport is an important sector contributing to environmental impact,but in IPAT it would be included within the broader technology term or activity patterns. It is too narrow to represent the general T factor requested in the question.

Option D:
Technology in IPAT encapsulates the resource and pollution intensity of economic activities. Cleaner technologies lower T and thus overall impact for given P and A values. This role matches precisely the description implied by the stem.

Statements A, B and D correctly summarise NEP 2020 teacher education reforms. The policy highlights a four-year integrated BEd rooted in strong disciplinary and professional preparation and expects teacher education to be located in multidisciplinary higher education institutions. It does not favour permanent isolation of teacher education from universities, and it emphasises appropriate regulation and quality assurance. Therefore C, E and F are incorrect because they either insist on stand-alone isolation or deny the need for regulatory oversight and common quality frameworks.

Option A:
Option A is incorrect because it includes only A and B and leaves out D, thereby neglecting the policy’s emphasis that teacher preparation must combine disciplinary depth with professional and pedagogical training.

Option B:
Option B is incorrect because it selects B and D and omits A, so it ignores the specific structural reform of introducing a four-year integrated BEd as a central route for teacher preparation.

Option C:
Option C is correct because it groups A, B and D, the three true statements about integrated programmes, multidisciplinary location and strong disciplinary foundations, while excluding C, E and F, which misrepresent NEP 2020’s stance on isolation and regulation.

Option D:
Option D is incorrect because it includes C, which favours permanent stand-alone teacher education institutions, contrary to NEP’s integration approach, and omits B, which describes that integration.
