UGC NET Questions (Paper – 1)

Statements A, B and C all correctly describe aspects of green campus initiatives. A is true because conserving energy and adopting renewables are central strategies for sustainability. B is correct as proper waste management and recycling reduce environmental impact. C is also true since awareness programmes shape attitudes and behaviours of students and staff. Statement D is false because higher education institutions are expected to model and promote environmental responsibility. Therefore, the combination A, B and C only is correct.

Option A:
Option A is correct because it includes all three positive and accurate descriptions of green campus practices and excludes D, which wrongly dismisses their relevance. It reflects how institutions integrate sustainability into operations and education.

Option B:
Option B is incorrect because, although A and B are correct, it omits C, which emphasises educational and awareness dimensions of sustainability. Without C, the role of student learning and behaviour change is underplayed.

Option C:
Option C is incorrect because it includes D along with B and C. Statement D contradicts contemporary expectations that campuses act as exemplars of sustainable living, so including it makes the combination wrong.

Option D:
Option D is incorrect because it treats all four statements as correct, which would endorse D’s claim that green initiatives are irrelevant. This is incompatible with policy directives and institutional practices worldwide.

Energy conservation refers to reducing energy use by avoiding waste and improving practices without necessarily changing technology. Turning off unused lights and fans directly cuts electricity consumption and is a classic conservation behaviour. The stem describes exactly this type of action,so energy conservation is the correct term. Therefore Option C fits best.

Option A:
Generation is producing electricity at power plants; it is not the household action described.

Option B:
Transmission is delivering electricity through the grid; it is not about switching off appliances at home.

Option C:
Energy conservation reduces energy use through behavioral or operational changes like switching off devices when not needed,matching the stem.

Option D:
Waste collection relates to solid waste management,not electricity saving behavior.

Statements A, B, C, D and F are correct and explain definitions of the three Rs, their role in shifting towards a circular economy and the need for awareness and infrastructure. Statement E is false because reducing, reusing and recycling generally conserve energy and lower greenhouse gas emissions compared to producing from virgin materials. Therefore, the correct combination is A, B, C, D and F only.

Option A:
Option A is correct since it captures all true statements and excludes only E, which wrongly denies energy and climate benefits of 3R actions.

Option B:
Option B is incorrect because it omits D and F, ignoring the circular economy shift and the enabling role of awareness/infrastructure.

Option C:
Option C is incorrect as it includes E, which is false.

Option D:
Option D is incorrect because it omits B (reuse), so it does not represent the full 3R framework.

Energy efficiency means using less energy to provide the same or better level of service,for example through LED bulbs or well insulated buildings. It reduces energy bills and emissions simultaneously. The stem explicitly refers to maintaining the same level of service with less energy input,which is the core definition of energy efficiency. Therefore Option A is correct.

Option A:
Improving energy efficiency can be achieved through technological upgrades,maintenance and behavioural changes. It is often considered the lowest cost option for reducing greenhouse gas emissions. These characteristics match the description given in the question.

Option B:
Energy scarcity describes a situation where energy resources are insufficient to meet demand. It is a structural condition,not a measure of how effectively energy is used,so it does not suit the stem.

Option C:
Energy mining refers to extracting energy resources such as coal or uranium from the ground. It increases supply rather than making use more efficient,so it is not relevant here.

Option D:
Energy pricing relates to the tariff structure and cost of energy for consumers. While it can influence efficiency behaviour,it is not itself the process of delivering the same service with less energy.

Statements A, C and D correctly describe key ideas about resource use and sustainable development. Statement A explains the regenerative nature of renewable resources when used within limits, C highlights the tragedy of the commons associated with overuse of shared resources and D emphasises the role of renewable energy and efficiency in sustainability. Statements B and E are incorrect because non-renewable resources are finite and their extraction and use often cause serious environmental damage. The combination that contains A, C and D only is therefore the correct answer.

Option A:
Option A is incorrect because it includes only A and C and leaves out D. While A and C are true, D is also correct in stressing policy directions for sustainable development. Excluding a correct statement makes this combination incomplete.

Option B:
Option B is incorrect because it includes A, C and E. Statement E is wrong as extraction and use of non-renewable resources typically lead to pollution, habitat destruction and greenhouse gas emissions. The inclusion of this false statement invalidates the option.

Option C:
Option C is incorrect because it adds statement B to the otherwise correct set. Statement B falsely claims that non-renewable resources are infinite and can be exploited without concern, which contradicts their finite nature and the need for conservation. Because it contains a wrong statement, this combination cannot be accepted.

Option D:
Option D is correct because it groups A, C and D, all of which are conceptually sound and aligned with the idea of sustainable resource management. It acknowledges the properties of renewable resources, the risks of overusing common property resources and the importance of shifting to clean energy and efficiency. By excluding the incorrect statements B and E, it becomes the only fully correct combination.

Green campus initiatives focus on making higher education campuses environmentally sustainable by reducing energy use, managing waste responsibly, increasing greenery and promoting eco-friendly transport. The stem lists actions such as installing solar panels, waste segregation and car-free zones, which are hallmark practices of green campus efforts. Thus, “green” correctly completes the sentence, making Option B the right answer.

Option A:
Green campuses serve as living laboratories where students can learn about sustainability through direct experience. They demonstrate institutional commitment to environmental responsibility, aligning perfectly with the examples given in the question.

Option B:
Digital initiatives focus on ICT adoption and online processes but do not specifically address energy, waste or transport in the environmental sense described here. Therefore, Option A is not suitable.

Option C:
Military initiatives would relate to defence or security preparedness and are not implied by the sustainability measures listed. Hence, Option C does not fit the stem.

Option D:
Purely ceremonial activities may involve symbolic events but do not necessarily change infrastructure or everyday practices. The question describes substantive infrastructural actions rather than ceremonies, so Option D is incorrect.
