UGC NET Questions (Paper – 1)

The area of a square is proportional to the square of its side, so if A₁:A₂ = 9:16, then (s₁²):(s₂²) = 9:16. Taking square roots of both sides gives s₁:s₂ = √9:√16 = 3:4. Thus, the side lengths must be in the ratio 3:4, which directly follows from the relationship between area and side for similar squares. No other option maintains this exact square–square root consistency.

Option A:
Option A is correct because it correctly applies the square root to the area ratio 9:16, converting it into a side ratio. Since area scales as the square of the side, this reverse operation is essential. The resulting ratio 3:4 is the only one consistent with both the given area ratio and the geometry of squares.

Option B:
Option B, 4:3, simply reverses the correct order and would imply that the square with area 9 units has the larger side, which contradicts the fact that 16 is greater than 9. If the second square has greater area, its side must be longer, not shorter, so 4:3 cannot be the correct side ratio.

Option C:
Option C, 9:16, repeats the area ratio rather than converting it to a side ratio and so ignores the square relationship. This would only be appropriate if areas themselves were being compared, not side lengths. Because the question explicitly asks for the ratio of sides, 9:16 is not valid here.

Option D:
Option D, 81:256, is the square of the given area ratio and would correspond to comparing higher powers of side lengths, not the sides themselves. It exaggerates the difference between the two squares and has no direct geometric justification in this context.

NEP 2020 explicitly states that rigid separation of streams should end. Students will be allowed to pick courses from different domains, such as physics with music or economics with computer science. This flexibility supports individual talents and multidisciplinary learning.

Option A:
This option captures the move away from rigid tracking and towards flexible curriculum design.

Option B:
Rigid streams are identified as a problem that the policy seeks to reform.

Option C:
Studying only one subject for four years would give a narrow education.

Option D:
Denying students any choice contradicts NEP’s focus on learner agency.

An open university is designed to widen access to higher education by offering flexible entry conditions, open and distance learning modes and minimal requirements for physical attendance. It typically caters to working adults, rural learners and others who cannot join regular campus-based programmes. The stem highlights flexible learning and the absence of rigid age or attendance rules, which are defining features of an open university. Hence, “open” is the correct completion of the phrase.

Option A:
A central university is established by an Act of Parliament and funded by the Union government, but it usually follows conventional admission and attendance norms. It does not necessarily guarantee flexible entry or distance-learning focus, so this option does not fully match the description in the stem.

Option B:
A state university is created by a state legislature and mainly caters to students within that state, generally through affiliated colleges or campuses. While some state universities may offer distance programmes, they are not specifically defined as open universities with open admissions. Therefore, this option is not the best answer here.

Option C:
An open university explicitly focuses on distance and flexible education, often using study centres, online platforms and print materials to reach learners. Its design aligns perfectly with the features described in the question, making this the appropriate option.

Option D:
A deemed to be university is an institution recognised for its excellence and granted university status by the central government on UGC’s recommendation. It is usually specialised and may follow selective admission and regular attendance requirements. Therefore, it does not inherently embody the open and flexible characteristics mentioned in the stem.

Statements A, B, C and E reflect the diagnostic and supportive nature of formative assessment, whereas D and F contradict its definition. Formative assessment is typically embedded during instruction to inform next steps, not reserved for end-of-course high-stakes decisions. ICT tools can gather diverse evidence such as quiz results and forum participation. Thus, the combination that includes A, B, C and E, but excludes D and F, is correct.

Option A:
Option A is correct because it unites real-time feedback, diagnostic use of data and evidence from online participation while rejecting the misuses described in D and F. It portrays formative assessment as ongoing and improvement-oriented.

Option B:
Option B is incorrect because it includes F, which wrongly states that formative assessment occurs only at the end of a course. Including F confuses formative with summative assessment, so this option cannot be accepted.

Option C:
Option C is incorrect because it incorporates F and omits B. While A, C and E are true, adding F introduces a false timing constraint that conflicts with standard definitions.

Option D:
Option D is incorrect because it accepts D, which advocates using formative scores for high-stakes decisions. Such use is generally associated with summative assessment and undermines the formative intent.

Many plastic carry bags are made of polymers that do not break down easily in natural environments. They can persist for decades,posing hazards to wildlife and clogging drainage systems. The stem points to this persistent pollution problem,so non biodegradable waste is the correct classification. Option B is therefore appropriate.

Option A:
Recyclable paper decomposes relatively quickly and can be reprocessed; it does not match persistent plastic litter.

Option B:
Non biodegradable wastes resist decomposition and accumulate in landfills and ecosystems; plastic carry bags are a classic example.

Option C:
Organic waste is biodegradable material like food scraps; plastics are not organic waste in this sense.

Option D:
Easily decomposable materials break down quickly; plastics show the opposite behavior.

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.

Copyright law grants authors certain exclusive rights such as reproduction, distribution and adaptation of their works for a specified period. In ICT contexts, respecting copyright is essential when using digital texts, images, software and multimedia. Violating these rights can lead to legal penalties and ethical breaches. Therefore, the protection described is copyright.

Option A:
Option A is correct because copyright is the standard legal concept that safeguards creators’ rights over original works, including digital content.

Option B:
Option B, copyleft, refers to a type of licence that requires derivative works to remain free and is not the general legal protection itself.

Option C:
Option C, freeware, indicates software that is free to use but still often under copyright.

Option D:
Option D, shareware, denotes software distributed on a trial basis, again usually still under copyright, not the protective regime itself.

Statements A, B, D, E and F are correct, whereas C is false. Universal instantiation and existential generalisation describe safe moves from general to particular and from particular to existential claims. Misusing these rules by upgrading “some” to “all” is a recognised error, and exam questions often test which conclusion correctly follows using quantifiers. The relationship between “Not all S are P” and “Some S are not P” illustrates how negation interplays with universal and existential force. Statement C is wrong because moving from “Some S are P” to “All S are P” overstates the information given. Hence A, B, D, E and F only is the correct combination.

Option A:
Option A is correct since it brings together the valid descriptions of the rules, the warning about misuse and the way quantifiers appear in UGC NET questions. It leaves out C, which treats a classic fallacy as if it were a valid rule. This combination therefore matches introductory predicate-logic guidance used in exams.

Option B:
Option B is incorrect because it includes C, thereby treating the invalid step from “some” to “all” as legitimate existential generalisation. That move has no logical justification and overgeneralises from limited information. Including C makes the whole option unsound.

Option C:
Option C is wrong as it omits A and adds C and F to B, D and E. Without A, the role of universal instantiation is not stated, and including C again endorses an invalid inference. Thus the set does not correctly represent the true statements.

Option D:
Option D is incomplete since it omits F, ignoring the important pattern relating “Not all” to an existential negative. While A, B, D and E are true, leaving out this quantifier-negation equivalence means the option does not capture all correct information.

Cultural transmission refers to the process by which media and other institutions pass on norms,values and traditions from one generation to the next. Children learn many behaviours and expectations from TV programmes. The stem clearly refers to this learning of social norms,so cultural transmission is the correct answer.

Option A:
Cultural transmission (media socialisation) is about passing norms,values and traditions to audiences,especially younger generations.

Option B:
Gatekeeping is the selection and filtering of information before publication,not value teaching.

Option C:
Surveillance is about informing people of events,not necessarily socialising them.

Option D:
Economic function concerns advertising and market activity,not the teaching of traditions.

NEP 2020 reaffirms the long-standing national goal of public investment in education at about 6% of GDP, arguing that this level is needed to realise the policy’s ambitious reforms.

Option A:
Around 3% of GDP is close to current spending levels and is considered insufficient for the required expansion and quality improvement.

Option B:
About 4% of GDP would be an increase but still falls short of the 6% target mentioned in the policy.

Option C:
This option correctly states the recommended 6% of GDP investment level highlighted repeatedly in NEP 2020.

Option D:
Ten percent of GDP is not the specified target in NEP 2020 and would be far above the recommended level.

Mass communication reaches large,heterogeneous audiences separated by time and space through media such as television,radio and newspapers. A national educational programme telecast to millions fits this description exactly. The flow is typically one-to-many and feedback is limited or delayed. Therefore,the correct term is mass communication.

Option A:
In mass communication,the message is designed for a broad audience rather than a specific individual or small group. The TV example in the stem fits this pattern,so mass is the appropriate choice.

Option B:
Interpersonal communication would involve direct contact between a small number of individuals rather than a nationwide broadcast.

Option C:
Intrapersonal communication concerns communication within an individual’s mind,not a programme sent to many people.

Option D:
Horizontal communication usually refers to message flow between peers within an organisation,not to broadcast media.

Watershed management treats a drainage basin as a single ecological and hydrological unit. It aims to conserve soil and water, improve vegetative cover and enhance livelihoods through coordinated actions in that area. The approach considers upstream and downstream linkages so that interventions are environmentally sound and socially beneficial. Therefore, an integrated view of land and water resources within a watershed, as expressed in option C, correctly defines watershed management.

Option A:
Option A is incorrect because focusing only on groundwater overlooks the interactions between rainfall, surface runoff, soil erosion and vegetation. Sustainable management requires attention to both surface and subsurface components of the hydrological cycle.

Option B:
Option B is incorrect since watershed programmes usually emphasise smaller structures like contour bunds, check dams and farm ponds rather than only large dams. The goal is to manage land and water at local scales, not just to build big projects on major rivers.

Option C:
Option C is correct as it integrates conservation and development goals. It recognises that soil conservation, water harvesting and vegetation restoration together can support agriculture, reduce drought vulnerability and improve rural incomes.

Option D:
Option D is incorrect because marine fisheries belong to coastal and ocean ecosystems, which are outside the usual scope of inland watershed projects. Different management frameworks are used for marine resources.

Coverage in questioning refers to how widely questions are distributed across students in the class. When a teacher consciously addresses students in different rows and corners,more learners become cognitively and behaviourally involved. The stem describes fairness in distribution,which directly relates to coverage. Therefore,coverage of questioning is improved.

Option A:
Coverage ensures that no small group of students monopolises interaction,creating a more inclusive classroom climate,so this option matches the aim described.

Option B:
Difficulty refers to the level of complexity of questions,not to who is asked. It is not the main focus in the stem.

Option C:
Secrecy has little relevance to classroom questioning,which is usually public and transparent.

Option D:
Formality describes tone or manner,not the distribution of questions.

Statement D is the only wrong statement because higher urban temperatures clearly affect public health through heat stress and increase energy demand for cooling. Statements A, B and C correctly describe what the urban heat island is and outline mitigation and adaptation measures such as greening and heat action plans. Heat-related morbidity and mortality have been documented for vulnerable city populations. Therefore, identifying D alone as wrong is the correct choice.

Option A:
Option A is correct because it isolates D as the single incorrect statement while treating A, B and C as valid. It recognises that urban heat has serious health and energy implications and that planning must address these. This option matches the requirement to select the wrong statement or statements.

Option B:
Option B is incorrect as it treats both A and D as wrong. Statement A correctly defines the urban heat island phenomenon and is widely used in urban climate studies. Including A among wrong statements shows a misunderstanding of the basic concept.

Option C:
Option C is incorrect because it groups B and D as wrong. While D is wrong, B is correct since green infrastructure is a recognised strategy for cooling cities. Misclassifying B undermines accepted adaptation measures.

Option D:
Option D is incorrect as it treats C and D as wrong together. C accurately identifies heat action plans, early warning and cooling centres as important adaptation measures. Including C among wrong statements makes this option unacceptable.

The word NET has three distinct letters: N, E and T. The number of permutations of n distinct objects taken all at a time is n!, so here it is 3!. Calculating 3! gives 3 × 2 × 1 = 6. Therefore, there are 6 possible distinct arrangements of the letters in NET.

Option A:
Option A uses the factorial formula for permutations correctly, recognizing that there are no repeated letters. By computing 3! as 6, it counts all possible orderings such as NET, NTE, ENT, ETN, TEN and TNE.

Option B:
Option B, 3, would be the number of letters, not the number of arrangements. It undercounts the permutations by ignoring the different orders in which letters can appear.

Option C:
Option C, 9, may come from incorrectly squaring the number of letters (3²), which does not match the combinatorial rule for arrangements of distinct objects.

Option D:
Option D, 12, overestimates the possible arrangements and could arise from misapplying permutation formulas that involve repetition or additional positions.
