UGC NET Questions (Paper – 1)

Each term is a block of four consecutive letters, and the block slides one position to the right each time: ABCD (1–4), BCDE (2–5), CDEF (3–6), DEFG (4–7). The next block must start at position 5 and cover 5–8, which is EFGH. Thus EFGH uniquely continues the sliding four-letter window.

Option A:
Option A, FGHI, is a valid four-letter block but starts at F, thereby skipping the block that should start at E. The series does not skip intermediate starting positions. Therefore FGHI is too far ahead to be the next term.

Option B:
Option B, EFGJ, begins correctly at E but breaks the requirement that letters inside the block be consecutive. J does not follow G directly. As a result, EFGJ does not maintain the strictly consecutive nature of the blocks.

Option C:
Option C, DEFG, repeats the last given term. The pattern clearly moves forward by one starting letter at each step. Since no repetition rule is indicated, DEFG cannot be the next term.

Option D:
Option D is correct because it starts at E, the letter immediately after D, and continues with F, G and H in order. It preserves both the block length and the consecutiveness of letters. Consequently, EFGH is the proper continuation of the series.

Content validity concerns whether the items of a test or instrument appropriately sample the entire domain of content that the test is supposed to measure. For example, an achievement test in research aptitude should include items across major topics such as types of research, sampling, tools and ethics, in proportion to their importance. High content validity arises when subject experts judge that the blueprint and items adequately cover the specified domain. Since the stem speaks of representing the full domain of content, it is clearly referring to content validity.

Option A:
Construct validity deals with whether a test truly measures the underlying psychological construct or trait it claims to assess, such as intelligence or motivation. It involves evidence from multiple sources, including correlations with other measures and experimental studies. Although related, construct validity focuses on the abstract construct rather than coverage of the content domain, so it is not the correct answer here.

Option B:
Criterion-related validity examines how well test scores correlate with an external criterion, such as future performance or another established measure. It is concerned with predictive or concurrent relationships, not with the breadth of content represented by the test items. Therefore, criterion-related validity does not match the emphasis on domain coverage in the stem.

Option C:
Content validity is often established through expert judgment, where specialists review the test blueprint and items to ensure all important facets of the domain are represented and that no irrelevant content is included. This process directly addresses the question of whether the test covers the intended content adequately. Because the stem focuses on this aspect, content validity correctly completes the statement.

Option D:
Face validity refers to the superficial impression that a test appears to measure what it is supposed to, based on the views of laypeople or examinees. It does not require systematic analysis of domain coverage and can be misleading. Since the stem asks about adequate representation of the full domain, face validity is not the appropriate term.

An Online Public Access Catalogue (OPAC) is a digital interface to a library's bibliographic database, enabling users to search holdings by various fields. It replaces traditional card catalogues and provides quicker, more flexible access to collection information. Modern OPACs may be accessible via the web from outside the library premises. Therefore, the system described in the stem is an OPAC.

Option A:
Option A is correct because the full form "online public access catalogue" is standard in library science, and the functions listed match those offered by OPACs.

Option B:
Option B, online personal article collection, is not a recognised term and would suggest a private store rather than a library's public catalogue.

Option C:
Option C, offline print accession card, refers to older manual cataloguing systems and does not involve computer interfaces.

Option D:
Option D, open password authentication check, sounds like a security procedure rather than a tool for searching library collections.

A digital signature uses algorithms and keys to bind the identity of a signer to a digital document in a way that tampering can be detected. It is legally recognised in many jurisdictions and supports secure e governance and e commerce. Unlike a mere image of a handwritten name, a digital signature has cryptographic strength. Thus, the method described is a digital signature.

Option A:
Option A is correct because digital signature is the standard term for cryptographically generated signatures used in secure electronic transactions.

Option B:
Option B, manual, signature refers to handwritten marks on paper and does not inherently support electronic verification or integrity checks.

Option C:
Option C, scanned, signature is just a picture of a manual signature and can be copied or altered without cryptographic safeguards.

Option D:
Option D, symbolic, signature is not a formal category in information security and could refer to any representation, lacking precise meaning.

Vyapti is the universal relation of pervasion linking hetu and sadhya such that the presence of the hetu guarantees the presence of the sadhya. It is learned through observation of positive and negative instances or through reliable testimony. Without vyapti, inference would lack its justificatory basis. Accordingly, the universal connection described in the stem is termed vyapti.

Option A:
Option A, paksha dharma, refers to a property present in the paksha, such as smoke on the hill, and is not itself the universal relation between hetu and sadhya. It designates a specific instance rather than a general rule.

Option B:
Option B, drstanta, is the example used to illustrate vyapti in familiar cases; while it helps communicate the relation, it is not the relation itself.

Option C:
Option C, trairupya, names the three characteristics of a valid hetu and is a test applied to reasons, not the pervading link between reason and probandum.

Option D:
Option D is correct because vyapti captures the idea that the hetu is found only where the sadhya is found. This connection enables the transition from observed sign to unobserved fact in anumana.

This series is generated by the rule “multiply the previous term by 3 and add 2”. We have 1×3+2 = 5, 5×3+2 = 17, 17×3+2 = 53 and 53×3+2 = 161. Applying the same rule to 161 gives 161×3+2 = 483+2 = 485. Hence 485 is the only value that continues the sequence in strict accordance with the recursive pattern.

Option A:
Option A gives 479, which cannot be written as 161×3+2 and would require subtracting an additional amount. This contradicts the consistently “+2” adjustment after multiplication by 3 in the earlier steps. Therefore 479 is not consistent with the rule.

Option B:
Option B gives 481, corresponding to 161×3−2, which would change the sign of the constant adjustment and break the established behaviour. Thus 481 is not a valid continuation of the series.

Option C:
Option C gives 483, equal to 161×3, but this omits the “+2” that appears in every transition. This makes the rule incomplete for the last step, so 483 cannot be accepted as correct.

Option D:
Option D gives 485, exactly equal to 161×3+2. It maintains the same transformation applied in all earlier steps, keeping the pattern transparent and stable. Consequently, 485 is the correct next term in the series.

A cross-sectional study captures data from a sample or several groups at a single point in time, providing a snapshot of the population’s characteristics or relationships among variables. It is commonly used in surveys to estimate prevalence or compare subgroups. Because it does not track changes over time, it is relatively efficient and economical. Therefore, the type of study described in the stem is known as a cross-sectional study.

Option A:
Longitudinal studies collect data from the same participants at multiple time points to examine change and development. They do not restrict data collection to one moment, so they do not fit the stem.

Option B:
Experimental studies involve manipulation of variables and control groups to test causality and can be cross-sectional or longitudinal in timing. The stem focuses solely on the single time-point nature of the design rather than on manipulation, so experimental is not the best choice.

Option C:
Option C, cross-sectional, accurately reflects the “snapshot” nature of the data collection described in the question. It may involve many participants at once, but only at one time point, which matches the stem.

Option D:
Panel studies are a form of longitudinal design in which the same individuals are followed over time; they explicitly contradict the single time-point characteristic mentioned. Hence, panel is not appropriate here.

Listening is more than just hearing sounds; it involves attention,interpretation and mental organisation. The behaviours in the stem show that the student is actively processing the lecture. Such engaged reception is what communication theorists call effective listening.

Option A:
Hearing is a physiological process that may occur even when attention is low. It does not guarantee understanding.

Option B:
Therefore listening is the correct term for the skill described because it includes active processing and organisation of the message.

Option C:
Encoding is a sender's activity of creating messages,not a student's role when following a lecture.

Option D:
Redundancy refers to repetition of parts of a message,not to the receiver's skill.

Each group is made of three consecutive letters, but the starting letters do not progress uniformly. They move from A to C (+2), from C to F (+3) and from F to J (+4), so the gaps themselves increase by one each time. Following this rule, the next starting letter should be J + 5 = O, and the three consecutive letters from O are O, P and Q. Therefore OPQ is the correct continuation.

Option A:
Option A, MNO, begins at M, which would correspond to a gap of only +3 from J and ignores the observed +5 requirement. It would make the sequence of gaps 2, 3, 4, 3 instead of 2, 3, 4, 5. Since the pattern clearly shows increasing differences, MNO does not fit.

Option B:
Option B, NOP, starts at N, representing a gap of +4 from J and essentially repeats the previous increase. This would produce a flat sequence of gaps at the end instead of a steadily growing one. Because the rule is that each new gap increases by one, NOP cannot be the next term.

Option C:
Option C is correct because the starting letter O is exactly five positions after J, which extends the gap sequence 2, 3, 4 to 5. The letters P and Q follow in order, preserving the internal structure of each group as three consecutive letters. Hence OPQ is the only option that satisfies both the gap rule and the block structure.

Option D:
Option D, PQR, begins even further ahead at P, yielding a gap of +6 from J. This overshoots the expected step and makes the sequence of gaps jump from 4 to 6. As there is no evidence of such a sudden larger jump, PQR is not a valid continuation of the pattern.

Statements A, B, D and E are correct because SDG 11 explicitly frames cities as inclusive, safe, resilient and sustainable, includes housing and services, addresses disaster risk and resilience, and mentions cultural and natural heritage. C is wrong since sustainable cities agendas go far beyond transport, and F is wrong because indicators and monitoring are essential tools for planning and accountability. Hence, the correct combination is A, B, D and E only.

Option A:
Option A is incorrect as it omits D and E, thus overlooking resilience and heritage protection, which are explicitly referenced in SDG 11. It reduces the agenda largely to overall framing and housing without key thematic sub-goals.

Option B:
Option B is correct because it collects all the true statements about SDG 11’s aims, targets and themes, and excludes C and F, which minimise or misrepresent the scope and governance needs of sustainable cities.

Option C:
Option C is incorrect since it includes C, which wrongly confines policy to transport, even though SDG 11 clearly spans housing, services, heritage and resilience. Including C means the option cannot be fully correct.

Option D:
Option D is incorrect as it accepts F, which dismisses the importance of monitoring, while excluding A. Dropping the overall aim of SDG 11 and accepting a statement that undermines evidence-based planning makes this combination conceptually unsound.

Statements A, B and C correctly outline prudent backup and compression practices, while D contradicts basic safety principles. Backups should be redundant and ideally off-device, with cloud services offering off-site resilience. Compression is a common method to save storage space or bandwidth but does not replace the need for multiple copies. Relying on a single device creates a single point of failure, so D is not acceptable. Therefore, the correct combination is A, B and C only.

Option A:
Option A is incomplete because it includes A and B but omits C. Although backups are central, understanding compression as a complementary strategy for efficient storage and transfer is also important.

Option B:
Option B is incomplete because it lists B and C only and leaves out A. Statement A emphasises the broader rationale for backup practices and should not be excluded when discussing data protection.

Option C:
Option C is correct because it brings together all the true statements about backups and compression and excludes the unsafe recommendation in D. It reflects the need for multiple copies and thoughtful storage management in ICT use.

Option D:
Option D is incorrect because it mixes A and C with D and treats D as correct. Suggesting that a single copy on one device is a good backup strategy exposes data to high risk of loss, so this option cannot be correct.

The series can be generated by the formula (a_n = 2n^4 + 3n^2 + 1) for n starting from 1. For n = 1, 2, 3, 4 and 5 we obtain 6, 45, 190, 561 and 1326, which match the question. For n = 6 the expression gives (2×6^4 + 3×6^2 + 1 = 2592 + 108 + 1 = 2701). Hence 2701 is the correct next term.

Option A:
Option A, 2665, is 36 less than the formula’s output and does not equal (2×6^4 + 3×6^2 + 1). It would require an unjustified reduction at the final term, so 2665 is not valid.

Option B:
Option B, 2683, remains below 2701 and fails to satisfy the expression for n = 6. Choosing 2683 would disrupt the quartic-plus-square structure of the sequence. Thus 2683 is not correct.

Option C:
Option C, 2723, overshoots the computed value and again cannot be obtained from the given formula. Using 2723 would break the algebraic pattern that has held so far. Hence 2723 is not appropriate.

Option D:
Option D, 2701, exactly equals the value generated by the rule for n = 6. It maintains the same functional relationship between n and a_n for all terms, so 2701 is the correct continuation of the series.

Statements A, B, C, D and F correctly describe similarities and differences between Nyaya and Western approaches, while E is false. Western syllogisms use a three-part structure, whereas Nyaya sets out five members to make explicit the thesis, reason, example, application and conclusion. This expanded form highlights vyāpti and its relation to the pakṣa, and exam items may unpack common examples into these steps. Both traditions, however, aim to justify conclusions with reasons. E is wrong because Western logic can represent long chains of reasoning by linking several arguments. Thus A, B, C, D and F only is the correct combination.

Option A:
Option A is correct since it draws a balanced comparison, showing structural differences without exaggerating them into absolute opposition. It also ties the theory to typical UGC NET questions. By excluding E, it avoids the mistaken idea that Western logic is limited to only three-step arguments.

Option B:
Option B is incomplete because it omits F, missing the important concluding point that both traditions share the goal of valid reasoning. Without F, the comparison sounds more divisive than it actually is. Therefore A, B, C and D only is not fully adequate.

Option C:
Option C is wrong as it includes E, treating Western logic as incapable of handling longer chains, which is clearly false in both classical and modern systems. Even simple derivations can involve many steps. Including E makes the combination unreliable.

Option D:
Option D is incorrect since it leaves out C and includes E, thereby ignoring the explicit role of vyāpti while accepting a false limitation on Western arguments. This mixture does not accurately reflect comparative logic.

Statements A, B and D are correct because a theoretical framework connects the study to theory, guides the choice and definition of variables and offers a perspective for interpreting results. Statement C is false since a framework does not replace the need for a thorough literature review. Statement E is also false because frameworks are often adapted or constructed rather than copied unchanged from one study. Therefore, the combination that includes A, B and D but excludes C and E is correct.

Option A:
Option A is correct because it identifies precisely the three useful functions of a theoretical framework without adopting the mistaken ideas that it eliminates literature review or must be copied exactly. It maintains a balanced view of theory as guidance, not as a rigid template.

Option B:
Option B is incomplete because it omits D, failing to highlight that frameworks are crucial in making sense of results and relating them back to theory. Without D, the interpretive role of the framework is underplayed.

Option C:
Option C is incorrect because it includes E, which wrongly insists on unmodified borrowing, and omits A, which clarifies the link between the study and broader theory. This combination distorts the flexibility with which frameworks are used.

Option D:
Option D is wrong because it accepts C, the claim that literature review becomes unnecessary once a framework is chosen. Including C contradicts the principle that empirical work should be grounded in and compared with a broad range of prior studies.

Plagiarism detection tools use text-matching algorithms to highlight similarities between a student's work and existing documents. They generate similarity reports that help instructors judge whether proper citation has been used. Such tools support academic integrity policies by discouraging copying without attribution. Therefore the software described is best classified as plagiarism detection software.

Option A:
Option A, translation, focuses on converting text from one language to another and does not systematically compare submissions with source databases for similarity checks.

Option B:
Option B, scheduling, assists in organising timetables or tasks and has no role in analysing textual originality.

Option C:
Option C is correct because the key functionality mentioned—comparing files to large repositories to flag overlaps—is the hallmark of plagiarism detection systems like Turnitin or other university tools.

Option D:
Option D, bandwidth monitoring, tracks network usage and traffic flows and is concerned with resource management rather than academic writing practices.
