UGC NET Questions (Paper – 1)

Statements A, B and C set out accepted principles of questionnaire construction: alignment with objectives, avoidance of double-barrelled wording and a clear, logical layout. Statement D is false because leading questions bias responses and threaten validity, and E is false since questionnaires often combine closed and open-ended items. Thus, the combination including A, B and C, and excluding D and E, is correct.

Option A:
Option A is incomplete because it does not include C, leaving out the importance of layout and sequencing for respondent comprehension and data quality. A and B alone do not cover all major design concerns.

Option B:
Option B is incorrect because it omits A, failing to stress that each item should relate directly to the study’s objectives, which is fundamental for content validity.

Option C:
Option C is wrong because it incorporates E, which incorrectly demands that all items be open-ended, and omits B, which correctly warns against double-barrelled questions. This mix of omission and error makes the option invalid.

Option D:
Option D is correct as it gathers the three statements that reflect good practice while rejecting D and E, which promote bias and an unnecessarily restrictive view of question format.

Each octal digit converts to a 3-bit binary pattern. For 73₈, the digit 7 maps to 111₂ and the digit 3 maps to 011₂. Combining these gives 111011₂. This pattern is the binary equivalent of the octal number 73.

Option A:
Option A is correct because 7→111₂ and 3→011₂, so 73₈ becomes 111011₂. This maintains the positional values exactly across bases.

Option B:
Option B, 111101₂, would represent octal 75₈, since 101₂ corresponds to 5. It therefore does not match the given octal number.

Option C:
Option C, 110111₂, maps back to octal 67₈, with groups 110₂ and 111₂ representing 6 and 7. This differs from 73₈.

Option D:
Option D, 101111₂, would correspond to octal 57₈. The grouping of bits does not align with 73₈.

Each group is a block of three consecutive letters written in reverse order: ZYX (26–24), WVU (23–21), TSR (20–18) and QPO (17–15). The starting letters move backward by 3 positions: Z, W, T, Q. The next starting letter is N (14), and the reversed block from 14–12 is NML. Thus NML continues both the block size and the backward progression.

Option A:
Option A, ONM, uses the same letters but in a different arrangement. It begins with O (15), not N (14), breaking the backward step of 3 from Q. Therefore ONM does not satisfy the starting-letter rule.

Option B:
Option B, MNO, lists the letters in forward order rather than reverse. The pattern clearly uses descending triples. As it reverses the direction within each block, MNO cannot be the correct continuation.

Option C:
Option C is correct because it starts at N, which is exactly 3 positions before Q, and presents the triple in descending order N, M, L. This mirrors the structure of the previous groups and adheres to the same step size in the starting letters.

Option D:
Option D, KJI, begins too far back and uses a starting letter K that is 7 positions before Q. This does not match the consistent spacing seen between earlier groups. Hence KJI is not compatible with the pattern.

The positions of the letters are A(1), C(3), F(6), J(10) and O(15). The successive differences are +2, +3, +4 and +5, forming an increasing sequence of natural numbers. The next difference should be +6, so the next position is 15 + 6 = 21, which corresponds to U. Therefore U is the only letter that continues the pattern of steadily increasing gaps.

Option A:
Option A, T, lies at position 20, giving a difference of 5 from O. This simply repeats the last increment instead of increasing it to 6. Since the series clearly shows the gaps growing by 1 each time, T does not meet the rule.

Option B:
Option B, U, is correct because its position 21 equals 15 + 6, matching the expected next difference. It maintains the idea that each step forward in the series uses a gap one larger than before. This adherence to the underlying numerical pattern makes U the valid continuation.

Option C:
Option C, V, at position 22, would correspond to a +7 jump from O. That goes beyond the required next difference of +6 and distorts the incremental pattern. As a result, V cannot be accepted as the next term in the series.

Option D:
Option D, W, at position 23, deviates even more from the predicted increment by adding 8. This breaks the smooth progression of 2, 3, 4, 5, 6 in the differences. Hence W is not consistent with the logic of the sequence.

NEP 2020 encourages the creation and use of high-quality OER to widen access, reduce costs and allow teachers to adapt materials to local contexts, provided quality and licensing norms are respected.

Option A:
Option A is incorrect because banning OER would limit access to affordable, adaptable learning resources and goes against the policy’s equity and openness goals.

Option B:
Option B is correct since it matches NEP’s positive stance on encouraging freely shareable, high-quality educational resources across subjects and levels.

Option C:
Option C is wrong because NEP promotes the use of OER throughout the education system, not only in private universities.

Option D:
Option D is incorrect as OER are meant for a wide range of curricular areas, not just for a narrow use such as sports coaching videos.

Statements A, B, C and E correctly describe the Nyaya distinction between pramāṇa as means of knowledge and prameya as the objects known, and give perception and inference as standard examples. D is false since the same object can be known via multiple pramāṇas. Hence the true statements are A, B, C and E only.

Option A:
Option A is correct because it includes both the conceptual distinctions and the exam-oriented statement, while excluding D, which restricts prameya in a way Nyaya does not accept.

Option B:
Option B is incomplete as it leaves out E, failing to mention common exam classification tasks.

Option C:
Option C is incorrect because it omits A, leaving out the definition of pramāṇa as a means of valid knowledge.

Option D:
Option D is wrong since it includes D (false) and omits B (true).

NEP 2020 calls for strengthening NIOS and state open schools so that children and youth who missed regular schooling can still complete their education. Open schooling offers flexible entry, pacing and modes, making it a key strategy for universalising school education.

Option A:
Abolishing open schooling would remove an important second-chance mechanism and go directly against NEP’s recommendation to expand and improve it.

Option B:
This option is correct because it directly states the inclusion-oriented purpose of open schooling: flexible pathways for those who dropped out or never enrolled.

Option C:
Reserving open schooling only for foreign nationals ignores its primary purpose of serving Indian learners who are out of school.

Option D:
Replacing all regular schools with open schooling is not suggested; NEP sees open schooling as complementary to, not a substitute for, regular schools.

Statements A, B and D are correct descriptions of learner participation techniques. A is true because brainstorming postpones judgement to enable free flow of ideas. B is true as think–pair–share structures participation from individual reflection to peer talk and whole-class sharing. D is true since role play allows students to experience different viewpoints through enactment. C is false because participation strategies benefit learners across ability levels, and E is false because equitable participation requires involving many students, not just a vocal minority; therefore A, B and D only is the correct combination.

Option A:
Option A combines A, B and D, accurately presenting brainstorming, think–pair–share and role play as participatory methods. It properly excludes C and E, which restrict participation to a few students or a narrow ability group, so this option is correct.

Option B:
Option B lists A and B but omits D, ignoring the role of role play in encouraging empathy and perspective-taking. Without D, the description of participation techniques is incomplete.

Option C:
Option C brings in B and D but leaves out A, underestimating the contribution of brainstorming as a widely used participation strategy. This omission means B and D only cannot be the full set of correct statements.

Option D:
Option D includes A, C and D but adds C, which wrongly limits the usefulness of participation techniques. Accepting C makes this combination logically unsound.

Option E extends A, B and D with C, again accepting the incorrect claim that such techniques are only for high-ability students. Because it mixes true and false statements, A, B, C and D only is not a valid answer.

Statements A, B, D and E correctly describe how bandwidth and QoS relate to e-learning services, while C and F are false. Bandwidth is a data rate, QoS can prioritise real-time traffic and low bandwidth leads to buffering. Monitoring usage allows institutions to make informed upgrade decisions. Networks rarely treat all traffic equally under congestion, and oversupply of bandwidth does not remove the need for management, so C and F must be excluded.

Option A:
Option A is correct because it integrates definitions, technical mechanisms, service quality effects and planning practices into one coherent set. It recognises that both capacity and management matter for reliable e-learning.

Option B:
Option B is incorrect because it omits E, and therefore does not mention monitoring and planning. While A, B and D are true, they do not cover the long-term capacity management aspect.

Option C:
Option C is incorrect because it excludes A, which provides the foundational concept of bandwidth. B, D and E are true, but without A, the explanation of what is being managed in QoS and capacity planning is incomplete.

Option D:
Option D is incorrect because it omits B, thereby ignoring QoS mechanisms as a way to protect time-sensitive traffic. A, D and E are correct, yet the absence of B weakens understanding of how networks can handle mixed applications.

The sequence is governed by aₙ = 2n⁴ + n² − 2 for n starting from 1. Substituting n = 1, 2, 3, 4 and 5 gives 2·1⁴+1²−2 = 1, 2·2⁴+2²−2 = 34, 2·3⁴+3²−2 = 169, 2·4⁴+4²−2 = 526 and 2·5⁴+5²−2 = 1273, confirming the rule. For n = 6 we have 2·6⁴+6²−2 = 2·1296+36−2 = 2592+36−2 = 2626. Thus 2626 is the unique value that continues this quartic-based pattern.

Option A:
Option A, 2594, is 32 less than the value mandated by the formula and does not satisfy 2n⁴+n²−2 for n = 6. It would require an unexplained reduction in the final term relative to the established rule. Therefore this option is not compatible with the structure of the sequence.

Option B:
Option B, 2610, is closer but still not equal to 2626 and again fails to arise from substituting n = 6 into the expression. Choosing 2610 would modify the pattern only at the last point, which is mathematically unsound. Hence option B is not correct.

Option C:
Option C, 2626, exactly matches the computed value from aₙ = 2n⁴+n²−2 when n = 6. It preserves the balance between the quartic and quadratic components that generated the earlier terms. Because it follows naturally from the same algebraic rule, 2626 is the correct next term in the series.

Option D:
Option D, 2642, overshoots the formula’s output by 16 and does not respect the rule 2n⁴+n²−2. Selecting 2642 would break the precise connection between term position and term value. Therefore option D cannot be accepted as a valid continuation.

An ad hominem fallacy attacks the person making the argument instead of addressing the argument’s content. In the statement, the speaker dismisses the climate change argument based solely on the speaker’s professional background, rather than examining evidence or logic. This makes the personal attribute irrelevant to the truth of the claim and shifts attention away from the actual reasoning.

Option A:
Option A, straw man, involves misrepresenting someone’s argument and attacking the distorted version, which is not happening here.

Option B:
Option B correctly identifies the focus on the person rather than the argument as the key flaw. The criticism targets who is speaking, not what is being said.

Option C:
Option C, appeal to pity, tries to win support by arousing sympathy rather than offering reasons, which is absent here.

Option D:
Option D, appeal to ignorance, argues that a proposition is true simply because it has not been proven false, which is a different kind of mistake.

NEP 2020 supports integrating scholarship schemes on the National Scholarship Portal to simplify applications, improve transparency and ensure that socio economically disadvantaged groups can more easily access financial aid.

Option A:
Offline only processing at district offices makes scholarship access slower and less transparent, which the policy wants to improve.

Option B:
This option reflects the digital unified portal approach that NEP recommends for scholarship administration.

Option C:
Restricting scholarships to urban private school students would violate the equity and inclusion goals of the policy.

Option D:
Removing scholarships altogether would harm disadvantaged learners and is contrary to NEP emphasis on financial support.

Statements A and B correctly describe major components of library automation: ILMS platforms streamline back-end operations, and OPAC interfaces support user searching. Statements C and D are false because barcode and RFID are standard in automated circulation, and ILMS can produce detailed statistical reports. Therefore the combination A and B only is correct.

Option A:
Option A is incorrect because it includes only A as correct and omits B. While ILMS functions are accurately described, OPACs are also crucial for user-facing search, so excluding B gives an incomplete picture of automation.

Option B:
Option B is correct because it recognises both ILMS and OPAC as central pillars of automated libraries. It appropriately excludes C and D, which contradict commonplace practices involving RFID, barcodes and reporting tools.

Option C:
Option C is incorrect because it suggests B and C are correct, thereby accepting C. Statement C wrongly claims that barcode and RFID cannot be used, which conflicts with their widespread adoption in libraries.

Option D:
Option D is incorrect because it groups A, B and C as correct, again accepting C. Since C misstates actual circulation technology, the combination cannot be considered accurate.

Statements A, B, C and E correctly describe basic statistical ideas, while D is false. The mean is influenced by extreme values, the median resists them better, standard deviation measures dispersion and in a normal distribution the three central tendency measures coincide. Effect size indeed reflects how large a difference or association is, complementing significance tests. However, a small p-value does not necessarily imply a large effect; with a big sample even tiny effects can be statistically significant.

Option A:
Option A omits E, ignoring the important interpretive role of effect size in judging the practical importance of findings. Without E, the explanation remains focused only on descriptive statistics and neglects the link to substantive significance.

Option B:
Option B leaves out B, so it fails to mention standard deviation, a key descriptor of variability, even though it comments on mean, median and effect size. This omission makes the option incomplete.

Option C:
Option C excludes A, thereby not recognising the difference in sensitivity to outliers between mean and median, which is a core interpretive issue. As a result, it cannot be accepted.

Option D:
Option D is correct because it combines all true statements about measures of central tendency, variability and effect size, while rejecting D, which mistakenly equates small p-values with large effects. It encourages a nuanced interpretation of statistical results.

Option E contains D, the false claim that a small p-value guarantees a large effect size, and so any combination including it becomes incorrect, even if other parts are true.

In educational theory, teaching is often represented as a relationship among teacher, student and content/subject matter. These three poles interact dynamically in every formal teaching situation. Therefore, the tri-polar process is best captured by teacher, student, content.

Option A:
Teacher,student,content correctly identifies the three essential elements in formal classroom teaching: the teacher mediates, the learner learns, and the content is the organised knowledge.

Option B:
Teacher,syllabus,exams overemphasises documents and assessment and omits the learner–content–teacher interaction as the core triad.

Option C:
Curriculum,library,principal are supportive institutional elements, not the essential poles defining the teaching process.

Option D:
Student,parents,community reflects wider social agents but misses the formal teacher–content relationship central to teaching.
