UGC NET Questions (Paper – 1)

Statements A, B, D and F together explain the logic of a national credit framework. A is true because integrating different pathways is a key goal. B is true as credits are meant to be portable across institutions and levels. D is true since recognition of prior learning allows existing competencies to be credited. F is true because multiple entry and exit are facilitated by credit accumulation. C is false because credit systems are designed to encourage mobility and lifelong learning, and E is false because credit frameworks can also cover part-time and online modes.

Option A:
Option A is incorrect because it omits F and therefore overlooks the multiple entry and exit possibilities enabled by credit accumulation.

Option B:
Option B is incorrect because it includes E, which wrongly excludes part-time and online learning from credit systems, contradicting flexible learning policies.

Option C:
Option C is correct as it selects A, B, D and F, the four statements that describe integration, portability, RPL and flexible pathways, while excluding C and E, which invert the purpose or narrow the scope of credit frameworks.

Option D:
Option D is incorrect because it includes C, which states that credit systems discourage mobility, contrary to their actual intent.

In the first hour, from 8:00 to 9:00 a.m., the first bus travels 40 km. After 9:00 a.m., the second bus starts and the relative speed between the two buses is 60 − 40 = 20 km/h. To close a gap of 40 km at a relative speed of 20 km/h, the second bus needs 40 ÷ 20 = 2 hours. Adding 2 hours to 9:00 a.m. gives 11:00 a.m. as the overtaking time.

Option A:
Option A, 10:00 a.m., would correspond to only one hour of catch-up time, which would close a distance of 20 km at a relative speed of 20 km/h, leaving 20 km still between the buses.

Option B:
Option B, 10:30 a.m., gives 1.5 hours of catch-up and would close 30 km of the gap, not the full 40 km, so the faster bus would still be behind.

Option C:
Option C, 11:00 a.m., correctly accounts for the full 2 hours needed at a relative speed of 20 km/h to cover the initial 40 km head start, exactly matching the required condition for overtaking.

Option D:
Option D, 11:30 a.m., overshoots the required catch-up time; by then, the second bus would have been ahead of the first bus for half an hour already.

An ISP operates the communication infrastructure that links end users to the global Internet. It allocates IP addresses, offers bandwidth plans and routes data packets between customer devices and external networks. Without an ISP or equivalent service, most individuals and campuses could not access web resources, email or other online applications. Hence, the central function is provision of Internet connectivity.

Option A:
Curriculum design and examination planning are academic policy tasks handled by bodies such as universities and regulatory agencies, not by ISPs. While educational institutions may consult ISPs for network needs, core academic functions remain separate.

Option B:
Manufacturing hardware is the domain of electronics companies. An ISP might purchase equipment from them but does not primarily produce devices like CPUs and monitors.

Option C:
Grading examination scripts requires academic judgement, which ISPs are not responsible for. Their role is in network provision, not educational assessment.

Option D:
This option correctly identifies that ISPs act as gateways between users and the wider networked world. They may also offer services like email or cloud storage, but these are built on the foundational service of providing access.

The differences between consecutive terms are 1, 2, 3, 4 and 5. These differences increase by 1 at each step, forming a simple arithmetic sequence. To continue this pattern, the next difference should be 6. Adding 6 to the last term 18 yields 18 + 6 = 24. This ensures that the growth at the level of differences remains smooth and systematic.

Option A:
Option A gives 22, which corresponds to a difference of 4 from 18 and repeats an earlier increment instead of moving to 6. This disrupts the steadily increasing sequence of differences. Therefore, 22 is not consistent with the pattern.

Option B:
Option B offers 23, giving a difference of 5, which again has already appeared in the series and fails to advance the difference pattern to 6. Thus, 23 cannot be accepted as correct.

Option C:
Option C yields 24, which is 6 more than 18 and extends the differences to 1, 2, 3, 4, 5, 6 in order. This maintains a clear and logical structure at the second level. Hence, 24 is the correct next term.

Option D:
Option D suggests 25, creating a difference of 7 from 18 and jumping beyond the expected increment. This makes the difference progression irregular. Therefore, 25 is not a valid continuation.

The Intergovernmental Panel on Climate Change is a scientific body established by UNEP and WMO to provide comprehensive assessments of climate change. It synthesises peer reviewed research on the physical science basis,impacts and response strategies. Its reports inform international negotiations and national policies. Thus the description in the question clearly points to the IPCC.

Option A:
UNEP,the United Nations Environment Programme,coordinates environmental activities within the UN system and assists developing countries. While it supports IPCC work,it is not itself the scientific assessment panel described in the stem. Therefore it is not the correct answer.

Option B:
UNDP,the United Nations Development Programme,focuses on development issues such as poverty reduction,governance and resilience. It uses climate information but does not produce global scientific assessments of climate change. Hence it does not match the concept in the question.

Option C:
UNFCCC,the United Nations Framework Convention on Climate Change,is the international treaty that provides the political framework for climate negotiations. It relies on IPCC assessments for scientific guidance but is not the assessment body itself. Therefore it is not the right option here.

Option D:
The Intergovernmental Panel on Climate Change regularly publishes assessment reports,special reports and methodology guidelines. By evaluating existing scientific literature,it offers authoritative syntheses rather than conducting original research. This role matches exactly what the question describes.

The rise in adaptation expenditure as a share of GDP shows that sectors like agriculture, water, infrastructure and social protection are being redesigned with climate risks in mind. It means that resilience building is now treated as part of normal development planning rather than an add-on. The Survey also notes that much of this spending comes from domestic public resources, underlining India’s argument that it is already investing heavily in adaptation while international finance remains inadequate. (India Budget)

Option A:
This option is incorrect because a higher share of GDP devoted to adaptation indicates greater, not lesser, importance given to resilience.

Option B:
This option correctly interprets the data as evidence of mainstreaming and highlights the burden placed on domestic finances in a climate-vulnerable developing country.

Option C:
Net-zero emissions relate to the balance between total emissions and removals; they cannot be inferred simply from adaptation spending figures.

Option D:
Modern adaptation includes proactive investments such as resilient infrastructure and early-warning systems, not only post-disaster relief; therefore this option narrows the concept incorrectly.

Statements A, B and C correctly define star, bus and ring topologies as described in networking theory. They specify how nodes connect to hubs, backbones and loops. Statement D is false because some topologies, especially star, can have single points of failure at central devices. Therefore the correct combination is A, B and C only.

Option A:
Option A is incorrect because it lists only A and B as correct and leaves out C. While A and B are true, C is also correct in describing a ring structure. Excluding C produces an incomplete summary of topologies.

Option B:
Option B is incorrect because it suggests A, C and D are correct, thereby accepting D. Statement D contradicts the idea of a central hub or shared cable that can cause widespread disruption if it fails.

Option C:
Option C is incorrect because it groups B and C only and omits A. Since star topology is one of the most common designs, an explanation that leaves it out is inadequate.

Option D:
Option D is correct because it brings together A, B and C as true and excludes D, which overlooks the possibility of single points of failure. This matches standard discussions of network design.

IPv4 stands for Internet Protocol version 4 and uses a 32 bit addressing scheme. These bits are often represented as four decimal octets separated by dots, such as 192.168.0.1. The 32 bit structure limits the total number of unique addresses that can be assigned. Therefore, the blank in the stem should be filled with 32 bits.

Option A:
Option A is correct because standard networking texts describe IPv4 addresses as 32 bit numbers, which is the basis for the dotted decimal notation commonly seen. This length explains the eventual exhaustion of IPv4 address space.

Option B:
Option B, 64, corresponds to some internal addressing schemes but not to the globally defined size of IPv4 addresses.

Option C:
Option C, 128, is associated with IPv6, the newer version of the protocol that expands the address space, not IPv4.

Option D:
Option D, 16, would allow far too few addresses to support modern networking and has never been the standard size for IP addressing.

The first-level differences are 13, 21, 29 and 37. These differences form an arithmetic progression with common difference 8. To keep this structure, the next difference should be 45. Adding 45 to the last term 107 gives 152, so 152 continues both the original sequence and the pattern among the differences.

Option A:
Option A gives 148, which corresponds to a difference of 41 from 107. This would produce differences 13, 21, 29, 37, 41, making the last increment among gaps equal to 4 instead of 8. Thus 148 does not respect the observed second-level behaviour.

Option B:
Option B gives 150, implying a difference of 43 from 107. The final step among differences would be 6, which still fails to match the constant increment of 8. Hence 150 does not align with the pattern.

Option C:
Option C gives 152, which implies a difference of 45 from 107. The sequence of differences becomes 13, 21, 29, 37, 45 and the increments remain 8 throughout. This perfect consistency at the second level makes 152 the correct next term.

Option D:
Option D gives 154, yielding a difference of 47 from 107. That would make the last increment among differences equal to 10, breaking the simple arithmetic progression. Therefore 154 is not a valid continuation.

Statements A, B, C and E correctly distinguish cluster and stratified sampling. Cluster sampling first selects natural groups, which is economical when populations are spread out, while stratified sampling divides the population into homogeneous strata and can preserve the population structure through proportionate allocation. Statement D is false because stratified sampling usually selects units randomly within each stratum, not by convenience. Hence, the combination including A, B, C and E and excluding D is correct.

Option A:
Option A is correct as it recognises the economic advantage of cluster sampling and the representativeness aim of stratified sampling, while rejecting the idea that selection within strata is merely convenient.

Option B:
Option B is incomplete because it omits E, failing to mention how proportionate stratified sampling mirrors the population composition. Without E, the representational strength of the method is underplayed.

Option C:
Option C is wrong because it includes D, the incorrect claim that stratified sampling relies on convenience within strata, and omits A, the key point about sampling natural clusters. This mix of omission and error mischaracterises both techniques.

Option D:
Option D is incorrect as it again accepts D and excludes B and C, thereby ignoring correct statements about homogeneous strata and the economy of cluster sampling. This leads to a distorted understanding of these probability sampling methods.

The University Grants Commission was established by a specific Act of Parliament with the explicit mandate to coordinate, determine and maintain standards of university education in India. It issues regulations on minimum standards, provides grants and oversees the functioning of universities. No other body has such a broad and system-wide jurisdiction over universities. Therefore, the only option that fits the description in the stem is the University Grants Commission.

Option A:
The University Grants Commission is the apex body for the university system as a whole, responsible for both funding support and regulatory norms. It interacts with central and state universities and lays down guidelines that institutions must follow to ensure quality. Because this aligns exactly with the statutory coordination and standard-setting role described, Option A is the correct choice.

Option B:
The All India Council for Technical Education deals mainly with technical and management education and approves specific programmes and institutions in those domains. Its mandate does not extend to coordinating the entire university education system across disciplines. Hence, Option B cannot complete the stem accurately.

Option C:
The National Council for Teacher Education focuses only on teacher education programmes such as B.Ed. and M.Ed. and regulates that single sector. Since the stem speaks about university education in general, NCTE’s narrow sectoral remit makes Option C unsuitable.

Option D:
The National Board of Accreditation accredits individual technical programmes rather than overseeing all universities. It evaluates programme quality but does not coordinate or maintain system-wide standards for university education, so Option D does not match the stem.

Statements A, B, C and E describe standard practices in data analysis, whereas D is false. Quantitative analysis relies on descriptive and inferential statistics, qualitative analysis uses coding and categorisation and mixed-methods studies often analyse each strand separately before integrating findings. In qualitative research, analysis and data collection can overlap, with emerging codes shaping further data collection. Statement D is wrong because quantitative analysis requires data; planning may occur earlier, but analysis itself cannot begin before data exist.

Option A:
Option A includes A, B and C but omits E, missing the important point that qualitative analysis is often iterative, beginning during data collection. Without E, the option does not fully represent the dynamic nature of qualitative analysis.

Option B:
Option B leaves out B, and thus fails to mention coding and categorisation as core qualitative techniques, even though it includes two other correct elements. This omission makes the description incomplete.

Option C:
Option C ignores A, thereby not stating that quantitative analysis normally uses descriptive and inferential statistics, which is fundamental in research methodology. As a result, it cannot be considered correct.

Option D:
Option D is correct because it combines all four true statements and excludes D, which misrepresents the timing of quantitative data analysis. It captures both the distinct and integrated aspects of quantitative and qualitative analysis.

Option E includes D, the false claim that quantitative analysis can start before data collection, and so the option becomes invalid even though it also contains true statements.

Blended learning strategically integrates traditional classroom sessions with online components such as forums, digital resources and assessments. This combination aims to exploit the strengths of both modalities, offering flexibility and richer interactions. When designed well, blended courses can enhance learner engagement and outcomes. Therefore, the approach described is blended learning.

Option A:
Option A is correct because the term blended learning is widely used in educational technology literature to denote precisely this mix of online and face-to-face experiences.

Option B:
Option B, isolated, would suggest separation rather than integration and does not convey the intentional combination of modes.

Option C:
Option C, rote, focuses on memorisation-based learning methods and is not tied to mode of delivery.

Option D:
Option D, unilateral, implies one-sided communication, which conflicts with the interactive nature of blended environments.

Chronic exposure to loud noise can damage the delicate structures of the inner ear, leading to partial or permanent hearing loss. It can also trigger physiological stress responses, elevate blood pressure and interfere with normal sleep patterns and cognitive performance. These combined effects make noise pollution a serious public health issue, particularly in urban and occupational settings.

Option A:
Option A is incorrect because long-term noise exposure tends to reduce concentration and disturb sleep rather than improve them.

Option B:
Option B is correct because it lists well-documented health impacts of noise, including hearing impairment, stress and sleep disturbances.

Option C:
Option C is incorrect because high noise levels often hinder clear communication and may lead to social irritation or conflict instead of enhancing interaction.

Option D:
Option D is incorrect since noise exposure does not confer immunity from cardiovascular diseases; in fact, it is associated with increased cardiovascular risk through stress mechanisms.

Statements D and F are wrong because they present highly biased and misleading views of responsibility for environmental problems. Saying the poor are the only cause of degradation ignores the much larger footprints of affluent groups and structural drivers. Claiming urban elites’ consumption has negligible environmental consequence hides the impact of high resource and energy use. Statements A, B, C and E correctly describe resource dependence, feedback from degradation, the role of social policies and structural conditions. Thus, the wrong statements together are D and F only.

Option A:
Option A is incorrect because it marks only D as wrong and ignores F, even though F also clearly misrepresents who drives environmental impact. By failing to include F, it underestimates the role of elite consumption and therefore does not fully answer the question.

Option B:
Option B is correct since it identifies exactly the two statements that wrongly attribute blame solely to the poor or minimise elite footprints. It implicitly validates A, B, C and E, which provide a more balanced understanding of poverty–environment linkages. This option meets the requirement to select the wrong statements.

Option C:
Option C is incorrect as it treats F alone as wrong and leaves out D. While F is indeed false, D is equally problematic in placing all responsibility on the poor. Selecting only F therefore gives an incomplete diagnosis of the errors.

Option D:
Option D is incorrect because it groups a correct statement C with the wrong statements D and F. C accurately notes that health, education and jobs can influence demographic patterns, so including it among wrong statements is unjustified and confuses the conceptual picture.
