UGC NET Questions (Paper – 1)

Statements A, B, C and E are correct because they reflect concerns about pollution havens, environmental clauses in trade rules, difficulties in tracing embedded impacts and the role of eco-labels in shaping markets. Statement D is false since there is no universal agreement that openness always improves environmental quality; outcomes depend on policies and structures. Statement F is false because environmental measures can sometimes be manipulated as disguised protectionism. Therefore, the combination A, B, C and E only is correct.

Option A:
Option A is incorrect as it omits E and so fails to consider the role of eco-labelling and certification in influencing consumer choices and firm behaviour.

Option B:
Option B is incorrect because it includes F, which incorrectly claims that environment-related trade measures can never be misused, despite evidence of such concerns in trade debates.

Option C:
Option C is correct since it combines structural, regulatory and market-based aspects of trade–environment linkages while rejecting overly optimistic or naive claims about openness and trade measures.

Option D:
Option D is incorrect as it includes D, which overstates consensus on the environmental benefits of trade openness, and excludes A, which describes a major environmental concern related to relocation of polluting industries.

World Environment Day is a global platform for encouraging awareness and action for the protection of the environment. It is led by the United Nations Environment Programme and celebrated annually on 5th June. The day is used to highlight a specific environmental theme each year and mobilise governments, organisations and citizens. Thus, the correct date of observance is 5th June, making Option B the right answer.

Option A:
Option A is incorrect because 5th January has no special global status as World Environment Day. Confusing these dates can lead to mistakes in questions related to environmental events.

Option B:
Option B is correct as it identifies 5th June as the internationally recognised date for World Environment Day. This date has been associated with environmental campaigns and activities across the world since its establishment.

Option C:
Option C is incorrect; 15th August is celebrated as Independence Day in India, not as World Environment Day. It marks a political event rather than an environmental observance.

Option D:
Option D is incorrect; 10th December is observed as Human Rights Day by the United Nations. While important, it is not linked to the World Environment Day campaign.

Statements A, B and D are correct because resilient cities need infrastructure planning, consideration of vulnerable groups and effective early warning and preparedness mechanisms. Statement C is incorrect since contemporary resilience thinking explicitly includes social inclusion, governance and equity aspects. Thus, the combination A, B and D only, excluding C, is correct.

Option A:
Option A is incorrect because it includes only A and B and leaves out D, even though D correctly identifies preparedness measures as part of resilience. Without D, the set of statements does not fully represent urban climate resilience strategies.

Option B:
Option B is incorrect since it adds C to A and B, treating C as true. C wrongly suggests that resilience neglects social inclusion, contradicting widely accepted frameworks such as resilient and inclusive cities.

Option C:
Option C is incorrect because, although it includes B and D, it also accepts C which is wrong. The presence of C makes the combination logically inconsistent with the concept of resilience.

Option D:
Option D is correct as it groups the three statements that jointly describe infrastructure, vulnerability and preparedness aspects of climate-resilient cities while excluding the misleading statement C.

A wildlife sanctuary is declared mainly for the protection of animal species and their habitats. Certain human activities may be permitted as long as they do not seriously disturb wildlife. This aligns with the stem’s description of protection from hunting while allowing limited human use. Therefore wildlife sanctuary is the correct term.

Option A:
Biosphere reserves are larger areas that integrate conservation,development and logistic support functions with core,buffer and transition zones. They involve broader objectives than simply protecting animals from hunting. Thus they are not the best match for the narrow description in the question.

Option B:
Wildlife sanctuaries provide safe areas where killing or capturing of animals is regulated or prohibited. Human activities like grazing or fuelwood collection may be allowed with restrictions. This structure corresponds closely to the conditions named in the stem.

Option C:
National parks typically impose stricter controls on human activities,with an emphasis on conserving whole ecosystems and landscapes. Extractive use of resources is usually prohibited. The stem suggests some limited human use,which suits sanctuaries more than national parks.

Option D:
Reserve forests are areas notified for forest conservation under forest laws and may focus primarily on timber and resource management. Wildlife protection is often secondary,so this term does not capture the protection from hunting highlighted in the question.

Mission estimates suggest that by 2030 the green hydrogen ecosystem could attract investments exceeding ₹8 lakh crore and create over six lakh jobs. By substituting green hydrogen for imported fossil-based feedstocks and fuels, it can lower the import bill and enhance energy security. It is also expected to avoid roughly 50 MMT of CO₂ emissions per year, thereby supporting India’s mitigation goals while enabling new green industries. (Press Information Bureau)

Option A:
This option is incorrect because official projections emphasise very substantial investments and emission reductions, not “minimal” impacts.

Option B:
This option correctly captures the multiple economic and environmental benefits that the mission is expected to deliver, connecting climate action with jobs and energy security.

Option C:
Although exports are an opportunity, the mission also targets domestic decarbonisation in sectors like fertilisers, refineries and steel; it is not export-only.

Option D:
Green hydrogen depends on renewable power; it does not replace renewables but builds on their expansion, so this statement is conceptually wrong.

Statement D is wrong because carrying capacity is highly relevant to debates on population and sustainable development, highlighting ecological limits. Statements A, B and C are correct: they define carrying capacity, show its dependence on consumption and technology and explain consequences of overshoot. Thus, the combination that identifies D alone as wrong is correct.

Option A:
Option A is incorrect because it marks A as a wrong statement, but A is a correct definition of carrying capacity (maximum population without long-term degradation). Misclassifying a true definition makes this option invalid.

Option B:
Option B is incorrect because it groups A with D as wrong, even though A is correct. Including a correct statement among the wrong ones makes the combination unacceptable.

Option C:
Option C is incorrect since it marks both C and D as wrong. C is actually correct in noting that exceeding carrying capacity leads to depletion and stress, so this option incorrectly labels a true statement as wrong.

Option D:
Option D is correct because it singles out D as the only incorrect statement and implicitly acknowledges A, B and C as true. It aligns with the conceptual link between carrying capacity, population and sustainability.

Statements A, B, C, D and F are correct: early stages typically show high birth and death rates; death rates decline before birth rates in the transition phase causing rapid growth; resource pressure rises with rapid growth; final stage tends to low birth/death with stabilisation; and education/reproductive health policies influence progression. Statement E is false because demographic transition is central to population–environment analysis. Therefore, the correct combination is A, B, C, D and F only.

Option A:
Option A is correct because it includes all true statements (A, B, C, D, F) and excludes only E, which wrongly denies relevance of demographic transition to population–environment relationships.

Option B:
Option B is incorrect because it omits F, missing the policy drivers (education and reproductive health) that influence movement through stages.

Option C:
Option C is incorrect because it omits A; A is a standard feature of the early stage in demographic transition models.

Option D:
Option D is incorrect because it omits B, which explains the typical sequencing of mortality and fertility decline in the transition phase.

Statements A, B, D and E are correct because consortia support resource/faculty sharing, enable joint/dual degrees, help smaller institutions access shared facilities and allow sharing of best practices for quality enhancement. Statements C and F are incorrect because consortia do not automatically remove autonomy and public universities are not legally barred from forming consortia within regulatory norms.

Option A:
Option A is incorrect because it omits B and E, so it ignores joint degrees and best-practice sharing.

Option B:
Option B is incorrect because it includes C (false), which claims autonomy must be surrendered.

Option C:
Option C is correct because it includes all and only the true statements A, B, D and E while excluding C and F.

Option D:
Option D is incorrect because it omits E, so it misses the quality-enhancement role of sharing best practices.

In the demographic transition model, the phase where death rates fall rapidly due to improvements in health and sanitation while birth rates remain high is associated with a population explosion. The gap between birth and death rates is greatest, causing very rapid population growth. This leads to increased demand for land, water, energy and other resources, placing heavy pressure on the environment. Therefore, the stage described in option A correctly corresponds to rapid population growth and heightened resource stress.

Option A:
Option A accurately describes the second stage of demographic transition, often called the “early expanding” stage. In this stage, mortality declines but fertility is still high, producing a surge in population. The resulting population pressure can contribute to deforestation, overuse of water and encroachment on marginal lands.

Option B:
Option B is incorrect because when both birth and death rates are high, the population growth rate is relatively low. Although living conditions may be poor, the environmental pressure from population growth is not as intense as in the population explosion stage.

Option C:
Option C is incorrect since a low birth and low death rate stage is usually associated with stabilised population. In this stage, countries often have better technology and institutions to manage environmental impacts more effectively.

Option D:
Option D refers to a potential stage of population decline, where environmental pressure from population growth is not the key issue. While consumption patterns may still cause degradation, the stage does not match the description of rapid population growth.

Statements A, B, E and F are correct because they reflect the core ideas and institutional features of the SDG framework. Sustainable development is commonly framed as a balance of economic, social and environmental pillars, while the SDGs explicitly cover poverty, health, education and environmental goals. The agenda highlights multi-stakeholder partnerships and regular review processes at national and global levels. Statements C and D are incorrect because inter-generational equity is central to sustainable development and the SDGs are universal, applying to all countries.

Option A:
Option A is correct because it selects exactly those statements that align with the official formulation of the SDGs and sustainable development. It includes the three-pillar balance, the breadth of SDG goals, the role of partnerships and the monitoring architecture. At the same time, it excludes C and D, which misrepresent equity and universality in the SDG agenda.

Option B:
Option B is incorrect because it adds C, a statement that claims sustainable development must ignore inter-generational equity. This contradicts the widely cited definition that explicitly stresses meeting present needs without compromising future generations. Including C means this combination cannot represent the correct set of statements.

Option C:
Option C is incorrect as it includes D, which wrongly asserts that SDGs apply only to developing countries, and it omits E and F. By excluding the partnership and review elements, it ignores key implementation pillars while also accepting a false statement about SDG coverage.

Option D:
Option D is incorrect because it contains D as well as B, E and F. While B, E and F are true, accepting D would mean treating SDGs as non-universal, which is inconsistent with the global nature of the 2030 Agenda. Therefore, this option mixes correct and incorrect statements.

Extended Producer Responsibility (EPR) requires manufacturers to take back or ensure proper collection and recycling of their products after use. Electronics are a common target because they contain hazardous as well as valuable materials. The stem mentions post consumer products requiring end of life management,which matches electronic waste. Therefore Option B is the correct answer.

Option A:
Fresh vegetables are perishable goods whose waste is usually biodegradable and handled through normal organic waste systems. They are not the primary focus of EPR frameworks,so Option A is not suitable.

Option B:
Electronic waste includes discarded computers,phones and appliances whose safe disposal and recycling need organised systems. EPR shifts some responsibility for these systems to producers,matching the concept in the question.

Option C:
Groundwater resources require regulation but are not “products” returned to producers. EPR is product oriented,so Option C does not fit.

Option D:
Open spaces are environmental amenities,not items manufactured and sold by producers. They are not managed through EPR policies,so Option D is incorrect.

Agroforestry systems integrate woody perennials with agricultural crops and sometimes livestock in spatial or temporal arrangements. This approach enhances biodiversity,improves soil fertility and provides multiple products for farmers. The stem defines exactly this combination of trees with crops or animals,making agroforestry the correct term.

Option A:
Monocropping means growing a single crop species on the same land year after year,often reducing biodiversity and resilience. It is the opposite of the diversified systems described in the question,so it is not appropriate here.

Option B:
Agroforestry can include practices like alley cropping,home gardens and silvopasture. These systems embody the integrated land use concept highlighted in the stem and show why Option B is the best match.

Option C:
Strip mining is a surface mining technique used to extract minerals and is unrelated to agricultural combinations of trees and crops. It generally leads to land degradation rather than ecological enhancement.

Option D:
Hydroponics is a method of growing plants without soil using nutrient solutions. Although innovative,it does not inherently involve trees or livestock on the same unit in the way agroforestry does.
