UGC NET Questions (Paper – 1)

Statements A, B and C are correct as they reflect basic demographic concepts and policy responses to ageing populations. Statement D is incorrect because older persons often play key roles in community organisations, knowledge transmission and resilience-building. Thus, the combination that includes A, B and C and excludes D is the correct answer.

Option A:
Option A is incomplete because it leaves out C, which is a correct and important statement about planning age-friendly urban environments. Without C, the answer does not fully address policy implications.

Option B:
Option B is incorrect since it includes only B and C and omits A, which provides the core definition of population ageing. This omission makes the explanation conceptually weak.

Option C:
Option C is correct because it brings together definition, consequences and planning responses to ageing populations while rejecting the ageist claim in D. It aligns with the holistic treatment of ageing in development discourse.

Option D:
Option D is incorrect as it accepts D along with the other statements and claims all are correct. Including D, which falsely denies older persons’ contributions, makes the combination unacceptable.

The sequence is defined recursively by a₁ = 2 and aₙ₊₁ = 5aₙ + n for n ≥ 1. Using this rule we get a₂ = 5·2+1 = 11, a₃ = 5·11+2 = 57, a₄ = 5·57+3 = 288 and a₅ = 5·288+4 = 1444, which reproduces the given series. For n = 5 the next term is a₆ = 5·1444+5 = 7220+5 = 7225. Thus 7225 is the only value that fits the same recurrence structure for the sixth term.

Option A:
Option A, 7085, is significantly smaller than the recurrence output and does not equal 5·1444+5. It would require changing the multiplier or subtracting a large amount at the last step, neither of which is indicated by the previous terms. Hence option A is not concordant with the established pattern.

Option B:
Option B, 7155, is closer but still falls short of the correct value 7225, and it is not produced by the rule aₙ₊₁ = 5aₙ+n with n = 5. Choosing 7155 would introduce an unexplained discrepancy between the rule and the sequence. Therefore option B is incorrect.

Option C:
Option C, 7185, again does not satisfy 5·1444+5 and reflects an arbitrary reduction of 40 compared to the formula result. Since the recurrence has been obeyed exactly by all earlier terms, such a modification is unjustified. Option C is therefore incorrect.

Option D:
Option D, 7225, equals the exact value given by the recurrence for the sixth term. It continues the pattern of multiplying the previous term by 5 and adding the index, which explains all of the earlier numbers. Because it fits perfectly with the recursive rule, 7225 is the correct next term in the series.

PARAKH is envisaged as a National Assessment Centre for school education. Its full form, Performance Assessment, Review and Analysis of Knowledge for Holistic Development, directly reflects its role in improving assessment quality for holistic learning.

Option A:
This option is correct because it reproduces the official expansion of the acronym PARAKH as given in NEP 2020.

Option B:
Option B is a made-up expansion that sounds similar but does not match the official wording and shifts focus towards regulation and accreditation of “knowledge hubs”.

Option C:
Option C focuses on curriculum reform rather than assessment and does not correspond to the formal expansion of PARAKH.

Option D:
Option D relates more to higher education research and knowledge rather than school assessment, so it is not the correct full form.

In a positional system, the same digit can represent different values depending on where it appears. Its weight is determined by its position relative to the radix point. Each position corresponds to a specific power of the base. Therefore, the weight of a digit depends primarily on its position in the numeral.

Option A:
Option A, value, is the digit itself, but weight is not determined by digit alone; position controls the power of the base used.

Option B:
Option B is correct because each position has a place value (base^0, base^1, base^2, etc.), which determines the weight.

Option C:
Option C, symbol, is another way to refer to the digit; it does not determine the positional weight by itself.

Option D:
Option D, base, affects the system globally, but the specific weight of a digit in a numeral is determined directly by its position (as a power of the base).

Statements A, B, C and E are correct, whereas D and F are wrong and therefore form the correct set of wrong statements. Perception is shaped by fairness judgements, past experiences and beliefs, so students can perceive the same message differently. Teachers can engage students in reflective dialogue to make perceptions explicit and sometimes modify them. It is false to claim that perceptions never change, and equally false to say perception has no role because messages are purely objective in the classroom. Hence D and F are the wrong statements.

Option A:
Option A is incomplete because it identifies D only as wrong and ignores F, which also denies the role of perception. Perception clearly affects classroom communication, so both D and F need to be selected. Picking only D underestimates the number of incorrect statements.

Option B:
Option B is incorrect since it marks F only as wrong and overlooks D, which wrongly suggests that perceptions are fixed forever. Students’ views can evolve with new experiences, feedback and reflection. Therefore F only does not represent all wrong statements in the list.

Option C:
Option C is correct because it groups D and F, the two statements that conflict with established ideas about perception. It recognises that perceptions are both powerful and changeable and that they are deeply involved in classroom communication. This combination therefore matches the set of wrong statements requested.

Option D:
Option D is wrong because it adds C, a correct statement about differing perceptions, to the wrong set. C accurately reflects that two learners can interpret the same explanation differently. Including C among wrong statements makes C, D and F only an invalid choice.

Paralanguage refers to vocal features that accompany spoken words,such as pitch,volume and rate. These features influence how messages are interpreted,conveying emotions and emphasis. The stem mentions pitch,loudness and speed,which are classic elements of paralanguage.

Option A:
Proxemics deals with spatial distance,not sound characteristics.

Option B:
Paralanguage includes pitch,volume,rate and tone,which directly fits the stem.

Option C:
Haptics focuses on touch based signals like handshakes,not voice.

Option D:
Semantics involves meaning of words rather than how they are vocally delivered.

For n-bit 2's complement representation, the range of signed integers is from -2^(n-1) to 2^(n-1) - 1. For n = 4, this becomes -2^3 to 2^3 - 1, which is -8 to +7. Hence, the representable range in 4-bit 2's complement is -8 to +7.

Option A:
Option A, -7 to +8, reverses the endpoints and allows +8, which is not representable in 4-bit 2's complement. The positive limit is +7, not +8.

Option B:
Option B is correct because it aligns with the general formula for 2's complement ranges and matches 4-bit examples used in digital design. Values outside this range would overflow.

Option C:
Option C, -8 to +8, would contain 17 distinct integers, which cannot fit into 4 bits since 4 bits can represent only 16 distinct patterns.

Option D:
Option D, -7 to +7, is symmetric around zero and describes a sign-magnitude or ones-complement-like range, not the asymmetric 2's complement range.

An abstract is a concise overview of an entire research study, typically restricted to a small number of words. It summarises the research problem, objectives, methods, key results and major conclusions in a compact form. Readers often rely on the abstract to decide whether the full report is relevant to their interests. Thus, the brief summary described in the stem is correctly called the abstract.

Option A:
An appendix contains supplementary material such as questionnaires, detailed tables or additional analyses that support the report but are not central to the main text. It is usually placed after the references and does not serve as a concise summary of the study. Therefore, appendix is not the appropriate term for the blank.

Option B:
The abstract provides a snapshot of the research in a structured way, sometimes using subheadings like background, method, results and conclusion. It allows indexing services and databases to represent the study efficiently. These functions match exactly what the question describes.

Option C:
A bibliography or reference list gives detailed information about all sources cited or consulted in the study, arranged in a specific referencing style. It documents the scholarly context but does not summarise the study’s content. Hence, bibliography is not the correct answer.

Option D:
Endnotes supply additional comments or citations placed at the end of chapters or the document rather than at the bottom of individual pages. They offer elaboration or clarification, not a full summary of the report, so endnote does not fit the stem.

Option B – horizontal communication Communication can be classified according to its direction within an organization or group: downward, upward and horizontal. Horizontal communication occurs between individuals of roughly equal status, such as peers in a classroom. When students discuss ideas with one another in small groups, the flow of messages is primarily among classmates rather than from teacher to students. Hence, the pattern described in the stem is best characterized as horizontal communication.

Option A:
Option A, downward communication, describes messages that flow from higher authority to lower levels, such as teacher instructions to students. In the scenario given, however, the emphasis is on students talking to each other rather than receiving messages from the teacher. Therefore, downward communication does not match the situation.

Option B:
Option B, horizontal communication, occurs when members at the same level—here, the students—interact to share information, solve problems or coordinate tasks. Group discussions in class exemplify this peer-level exchange. This option therefore accurately labels the communication pattern described.

Option C:
Option C, upward communication, involves messages from lower levels to higher levels, such as student feedback or requests directed to the teacher or administration. The stem does not mention students addressing the teacher but instead focuses on peer discussion, so upward communication is inappropriate.

Option D:
Option D, one-way communication, refers to situations where messages go from sender to receiver without significant response or interaction. Group discussion, by contrast, is interactive, with students both sending and receiving messages. Hence, calling it one-way communication would be misleading.

Statements A, B, C and E together express the mainstream view on private participation. Private institutions can widen access when regulated, frameworks protect quality and student interests, policies discourage purely profit-driven motives and certain fee and transparency norms may be applied. Statements D and F are false because private HEIs are subject to accreditation and external regulation, and they may collaborate with public institutions in research and outreach.

Option A:
Option A is incorrect as it omits E and therefore does not acknowledge the specific role of fee regulation and transparency norms in regulating private institutions.

Option B:
Option B is incorrect because it introduces F, which bans collaboration between public and private institutions, contrary to common practice and policy recommendations.

Option C:
Option C is correct since it selects A, B, C and E, the four true statements on access, regulation, motivation and fee norms, while excluding D and F, which misrepresent regulatory obligations and collaboration possibilities.

Option D:
Option D is incorrect because it includes D, which wrongly exempts private institutions from regulation, and so conflicts with the basic legal framework governing higher education.

The Choice Based Credit System is designed to provide flexibility in curriculum through electives, skill courses and the ability to move across disciplines. It allows students to accumulate credits over time and supports a learner-centred approach. The stem describes a system that supports choice, interdisciplinary courses and credit accumulation across semesters, which fits the Choice Based Credit System exactly. Thus, Option B is the correct answer.

Option A:
The Annual Examination Scheme refers to conduct of examinations once a year without emphasising course choice or credit accumulation. It is an older pattern that does not by itself guarantee flexibility or interdisciplinarity, so this option is incorrect.

Option B:
The Choice Based Credit System explicitly incorporates the idea of credits linked to learning outcomes and workload, which can be combined in multiple ways to form a programme. It supports flexible pathways and interdisciplinary exposure, aligning well with the question.

Option C:
A Fixed Credit Regime implies a more rigid structure with limited or no flexibility for learners to choose courses or adjust pacing. This is contrary to the concept being described in the stem, so it is incorrect.

Option D:
The Term-End Promotion Scheme is not a recognised framework in higher education for structuring curricula and credits. It does not address choice or credit-based flexibility, so this option does not answer the stem appropriately.

The differences in the series are 3, 5, 7 and 9, which form an increasing sequence of odd numbers. To continue this pattern, the next difference should be 11. Adding 11 to the last term 26 gives 26 + 11 = 37. This maintains the smooth growth of the differences and fits well with the structure of the given series. Therefore, 37 is the only option that preserves the observed pattern.

Option A:
Option A provides 37, which is obtained by adding the next odd difference 11 to 26. The difference sequence 3, 5, 7, 9, 11 remains perfectly consistent and shows a clear second level arithmetic pattern. This makes 37 the logically correct continuation of the number series.

Option B:
Option B gives 35, which corresponds to adding 9 to 26 and simply repeating the last difference instead of increasing it. This breaks the rule that differences themselves should grow by 2 each time. Hence, 35 does not correctly follow the pattern governing the series.

Option C:
Option C gives 38, which would require a difference of 12 from 26, overshooting the next expected odd difference of 11. This disrupts the systematic progression of differences and introduces an unjustified jump. Therefore, 38 is not a valid extension of the series.

Option D:
Option D suggests 40, which would create a difference of 14 from 26 and move even further away from the orderly sequence of odd differences. Such a large change is inconsistent with the established pattern of gradually increasing differences. Thus, 40 cannot be accepted as the next term.

Statements A, B and D are correct descriptions of web browsers, whereas statement C is misleading. Browsers are application software for accessing web content, bookmarks save favourite URLs and extensions add extra features such as ad blocking or note-taking. Private or incognito mode mainly limits local storage of history and cookies on the device, but does not prevent all tracking by websites or network providers. Hence the correct combination is A, B and D only.

Option A:
Option A is incorrect because it lists only A and B as correct, omitting D. Although accessing web resources and bookmarking are important functions, extensions and add-ons are also widely used to extend browser capabilities. Leaving out D makes the description incomplete.

Option B:
Option B is incorrect because it treats all four statements as correct and therefore accepts C. Since C overstates the protection offered by private mode, including it results in a factually inaccurate combination.

Option C:
Option C is incorrect because it includes only B and D and omits A. A defines what a web browser is, so excluding it weakens the conceptual understanding of the tool. Additionally, this option does not address the inaccuracy in statement C.

Option D:
Option D is correct because it acknowledges basic browser functions and the role of extensions while rejecting the exaggerated privacy claim in C. It presents a realistic view of what private browsing can and cannot do.

Information overload occurs when the volume of available material exceeds a person’s capacity to process it meaningfully. The solution is not to consume more indiscriminately, but to become selective and strategic. Information literacy combines skills in formulating precise questions, choosing appropriate databases, using filters and evaluating authorship, evidence and bias. Learners who master these skills can turn abundance into an asset rather than a burden.

Option A:
Treating all sources as equally valid undermines academic quality and can lead to the use of misinformation. Scholars are expected to differentiate between peer-reviewed research, opinion pieces and unverified claims.

Option B:
This option correctly emphasises a proactive, skills-based approach to managing digital information. By learning how to search and evaluate systematically, students can focus on the most relevant and trustworthy resources, saving time and improving the quality of their work.

Option C:
Completely avoiding digital resources would cut learners off from up-to-date research and many primary documents. It is neither realistic nor desirable in contemporary higher education.

Option D:
Copy-paste behaviour without reading constitutes poor scholarship and often leads to plagiarism. It does not contribute to understanding and ignores the need for synthesis and critical thinking.

Statements A, B and C accurately describe key affordances of digital note-taking tools, while D is false. Many applications sync across devices, accept stylus-based handwriting and support tags and search to manage large volumes of notes. Collaboration and sharing features are increasingly common, so it is incorrect to say that such tools necessarily block collaboration. Therefore, the only fully correct set of statements is A, B and C.

Option A:
Option A is correct because it brings together the main learning-related strengths of digital note-taking without including the restrictive and incorrect claim in D. It highlights portability, input flexibility and retrieval efficiency, which are all valuable for students.

Option B:
Option B is incomplete because it includes only A and B and omits C. Without mentioning tags and search, the description underestimates how these tools support efficient retrieval and organisation of information.

Option C:
Option C is incomplete because it lists only B and C and leaves out A. Statement A about cross-device storage and organisation is fundamental to the appeal of such tools in ubiquitous learning contexts.

Option D:
Option D is incorrect because it treats all four statements as correct and thereby accepts D. Since many note-taking tools explicitly offer sharing and collaborative editing, claiming that collaboration is impossible is wrong.
