UGC NET Questions (Paper – 1)

A, B, D and E are correct; C is false. Cārvāka privileges perception, is sceptical about inference beyond direct experience, and is critical of Vedic ritual authority. It is covered in UGC NET Indian logic/epistemology.

Option A:
Option A is correct because it includes all true statements and excludes C, which wrongly attributes Vedic acceptance to Cārvāka.

Option B:
Option B is incomplete because it omits E (syllabus relevance), which is true.

Option C:
Option C is incomplete because it omits A (materialist identification), which is true.

Option D:
Option D is incorrect because it includes C (false).

Non-sampling errors are all sources of survey inaccuracy that do not stem from the act of sampling but from the way data are collected, recorded or processed. They include interviewer bias, faulty questionnaire design, respondent misunderstanding and coding or tabulation mistakes. Such errors can be large and may not decrease simply by increasing sample size. Therefore, errors arising from inaccurate responses or defective tools are correctly termed non-sampling errors.

Option A:
Non-sampling errors encompass diverse problems such as ambiguous questions that confuse respondents, poorly trained interviewers and data entry errors. These issues affect the quality of information gathered from each selected unit and can seriously distort findings. Since the stem emphasises inaccurate responses and processing mistakes, this option is appropriate.

Option B:
Random error refers to unpredictable fluctuations that occur by chance and may be part of both sampling and measurement processes; it is not restricted to the specific systematic problems listed.

Option C:
Proportional error is not a standard category in survey methodology and does not describe the cluster of issues like tool defects and processing mistakes.

Option D:
Experimental error is associated with variability in experimental outcomes and does not specifically refer to survey response or instrument problems, so it is not correct here.

A Type I error occurs when the null hypothesis is actually true but the sample data lead the researcher to reject it, suggesting an effect that does not exist in the population. It is also called an alpha error or false positive. The chosen significance level, such as 0.05, represents the maximum probability of committing this kind of error under repeated sampling. Therefore, incorrectly rejecting a true null hypothesis is known as a Type I error.

Option A:
Option A clearly labels this error as Type I, which is central to decisions about the significance level and interpretation of p-values. Researchers aim to keep the probability of such false alarms low, consistent with the description in the stem.

Option B:
A Type II error, by contrast, occurs when a false null hypothesis is not rejected, leading to a failure to detect a real effect; this is a false negative situation, not the false positive described. Hence, Type II is not the correct answer.

Option C:
Sampling error refers more broadly to the natural differences between sample statistics and population parameters due to using a subset of the population. While related to hypothesis testing, it is not the specific decision error of rejecting a true null.

Option D:
Measurement error involves inaccuracies in data due to instrument flaws or respondent factors and is different from the inferential decision errors in hypothesis testing, so it is not appropriate here.

Statements A, C and E correctly summarise the main purposes of research. Research certainly attempts to describe, explain and understand phenomena, and it often seeks to predict or control events when conditions permit. It also contributes to both knowledge creation and practical problem solving in society. By contrast, B is false because research may challenge existing beliefs, and D is false because educational research is not confined to laboratories.

Option A:
Option A is correct because it includes A, C and E, which are all true, and excludes B and D, which wrongly restrict or misrepresent the purposes of research. The combination recognises that research can be descriptive, predictive and problem oriented. It also acknowledges that educational research can occur in natural and institutional settings, not only in laboratories.

Option B:
Option B is incorrect because it adds B, which wrongly claims that confirmation of what is already known is the only purpose of research. Including B implies that research is never exploratory or critical, which contradicts the open-ended nature of inquiry. Even though A, C and E are true, the presence of B makes the overall combination false.

Option C:
Option C is wrong because it includes both B and D, which are false statements, and omits A and C, which are true. It thereby misrepresents research as mainly confirming prior beliefs and limiting educational research to laboratories. This fails to capture the broader descriptive, explanatory and applied purposes of research.

Option D:
Option D is incorrect because it brings in D, a false statement that confines educational research to lab experiments. While A and C are true, mixing them with D distorts the understanding of where educational research can be conducted. The omission of E also means that the role of research in social problem solving is ignored.

Mobile learning refers to educational activities that are supported or enhanced through portable digital devices such as smartphones and tablets. It allows learners to access content anytime and anywhere, extending learning beyond the classroom. ICT has made mobile learning a major trend in contemporary education. Hence, the appropriate term is mobile learning.

Option A:
Option A is correct because m learning is a well known abbreviation for mobile learning, directly tied to the use of portable devices.

Option B:
Option B, distance, learning involves separation of teacher and learner in space and sometimes time, but it may or may not use mobile devices specifically.

Option C:
Option C, remedial, learning focuses on addressing learning difficulties and is not defined by the use of mobile technologies.

Option D:
Option D, reflective, learning emphasises critical thinking and self examination, which again is not inherently connected to handheld devices.

Statements D and F are wrong because ozone depletion does affect terrestrial plants, phytoplankton and food webs, and the ozone layer has not yet fully recovered, requiring ongoing compliance with treaties. A, B, C and E are correct: the ozone layer filters UV-B, excess exposure increases health risks, the Montreal Protocol guides phase-out of harmful substances and protective behaviours reduce risk. Therefore, the correct answer is the combination that identifies D and F as the wrong statements.

Option A:
Option A is correct since it pinpoints both D and F as misrepresenting scientific and policy realities, while accepting A, B, C and E, which align with current understanding of ozone protection and UV impacts. It reflects both ecological and human health dimensions.

Option B:
Option B is incorrect because it singles out only D and ignores F, even though claiming treaties are no longer needed is clearly inconsistent with ongoing monitoring and gradual recovery timelines.

Option C:
Option C is incorrect as it marks only F as wrong and overlooks D, which denies the ecological consequences of ozone depletion. By failing to include D, it neglects an important environmental dimension of the issue.

Option D:
Option D is incorrect because it adds C to the list of wrong statements, even though C correctly notes that the Montreal Protocol has been central in guiding the replacement of ozone-depleting substances. Including C among wrong statements contradicts widely accepted historical facts.

In high context cultures,much of the meaning is conveyed through shared background,implicit cues and non verbal signals rather than explicit verbal detail. Traditional Indian families generally share close relationships,common values and repeated interaction,so family members can often understand intentions without elaborate explanation. This makes their communication relatively high context.

Option A:
Low context communication requires speakers to spell out meaning directly in words because shared background is limited,which does not fully characterise traditional family settings.

Option B:
High context communication relies heavily on situational knowledge and relational history,which fits long standing family interactions. The stem alludes to this reliance on implicit understanding,so high context is the appropriate answer.

Option C:
Zero context is not a standard category in Hall's theory and would incorrectly imply that context plays no role.

Option D:
Technical context would refer to specialised professional or scientific settings rather than family life.

For 458₉: 4×9² + 5×9¹ + 8×9⁰ = 4×81 + 5×9 + 8 = 324 + 45 + 8 = 377. Therefore, the decimal equivalent is 377.

Option A:
Option A correctly applies base-9 positional weights and sums to 377.

Option B:
Option B (365) is too small and reflects an error in weighting or addition.

Option C:
Option C (389) is too large and would require extra value not present in the digits.

Option D:
Option D (401) is far above the correct sum and cannot arise from 4,5,8 with powers 81,9,1.

Time management refers to how effectively a teacher allocates and uses the available instructional period to achieve lesson objectives. Completing planned activities within the set time indicates that the teacher has paced the lesson appropriately. The stem therefore points to effective time management.

Option A:
Managing space involves arranging seating and classroom layout,which is important but different from completing tasks within a time limit.

Option B:
Time management helps prevent rushing at the end of the period or leaving objectives incomplete,so option B is the most accurate description of the behaviour mentioned.

Option C:
Financial management concerns handling budgets and resources at institutional levels,not controlling the length of classroom activities.

Option D:
Personnel management refers to supervising staff or human resources,rather than managing instructional time with students.

Randomisation is the process of assigning participants to experimental and control groups using random mechanisms, such as random number tables or computer-generated sequences. This practice helps ensure that groups are equivalent on both known and unknown variables at the start of the experiment. By reducing systematic differences between groups, randomisation strengthens internal validity and makes it more likely that observed effects are due to the treatment. Hence, the procedure described in the stem is correctly called randomisation.

Option A:
Stratification involves dividing a population into homogeneous subgroups and can be used before sampling or randomisation, but it does not by itself eliminate selection bias in group assignment. It is more related to sampling than to within-experiment group allocation, so it is not the best answer.

Option B:
Matching pairs participants on certain characteristics such as age or ability before assigning them to groups, which can improve equivalence on those specific variables, but it is not purely random. It cannot control for all unmeasured variables, so it differs from the chance-based process emphasised in the stem.

Option C:
Option C, randomisation, uses chance to distribute both measured and unmeasured characteristics across groups, reducing the risk that pre-existing differences, rather than the treatment, explain outcomes. This aligns exactly with the purpose stated in the question.

Option D:
Standardisation refers to keeping procedures, instructions and conditions uniform across participants to reduce procedural variation. While important for internal validity, it does not address selection bias in the same way randomisation does.

Statements A, B and C correctly describe the role of community colleges and vocational education within higher education. A is true because community colleges are designed to respond to local skill needs through short-term and flexible programmes. B is correct in highlighting practical training and employability as central goals of vocational education. C is also true since recent reforms encourage multiple entry and exit options to integrate vocational pathways. D is false because policy documents recognise community college and vocational programmes within the larger higher education framework. Therefore the correct combination is A, B and C only.

Option A:
Option A is incorrect because it recognises A and B but excludes C, which is an important policy feature linking vocational education with flexible curricular structures. By omitting C, this option fails to represent the complete set of correct statements.

Option B:
Option B is incorrect because it includes B and C but leaves out A, which accurately explains the local skill-based orientation of community colleges. Without A, the description of these institutions is incomplete.

Option C:
Option C is correct because it combines all three true statements and excludes D, the statement that wrongly denies policy recognition. It thus presents a coherent understanding of how vocational and community college programmes fit into higher education.

Option D:
Option D is incorrect because it includes A and C but omits B, which clearly captures the central objective of vocational education in enhancing employability. Leaving B out makes this combination only partially true.

Statements A, C and D give standard facts about quantifiers. A correctly identifies “for all n” as a universal quantifier. C is true because the negation of a universal statement is an existential statement with the predicate negated. D is also correct since negating an existential claim yields a universal statement with negated predicate. B is false because no natural number squared equals 2, and E is false because not all natural numbers are even. Therefore A, C and D only are correct.

Option A:
Option A is correct as it lists all the true statements: it recognises the universal quantification in A and the standard negation rules in C and D, while properly excluding B and E, which misstate facts about ℕ.

Option B:
Option B is incomplete since it omits D, ignoring the second important pattern for negating an existential statement. It therefore does not capture the full set of correct statements here.

Option C:
Option C is wrong as it drops A and includes only C and D, failing to mention the basic identification of a universal quantifier in statement A.

Option D:
Option D is incorrect because it adds E, which incorrectly claims that every natural number is even, so the combination contains a false universal statement.

NEP 2020 strongly recommends that young children learn in their home language, mother tongue or local language at least till Grade 5, as this supports better comprehension, confidence and concept formation.

Option A:
This option directly reflects NEP 2020, which emphasises using the child’s home, mother tongue or local language as the medium of instruction in the early years.

Option B:
NEP 2020 does not prescribe English as the only medium; it may be taught as a subject but is not imposed as the sole language of instruction in early grades.

Option C:
Choosing any foreign language as the main medium in early grades would be pedagogically unsound and is not suggested in the policy.

Option D:
Sanskrit is encouraged as an optional language, but NEP 2020 does not ask that it be the compulsory medium of instruction for all students.

Extrinsic motivation arises from external rewards or pressures,such as grades,praise or prizes. Learners engage in tasks to obtain these outcomes rather than for inherent interest. The stem lists grades and certificates as motivators,so the type of motivation is clearly extrinsic.

Option A:
Intrinsic motivation stems from curiosity and enjoyment of the task itself,which is not emphasised when external rewards dominate.

Option B:
Extrinsic motivators can be useful if used carefully,but over-reliance may reduce intrinsic interest,which is why distinguishing them is important. Option B correctly captures the source of motivation described.

Option C:
Normative influences involve conforming to social norms and expectations rather than responding to explicit rewards.

Option D:
Compulsory motivation is not a standard term and would suggest acting only because one is forced,which is not the focus on prizes in the stem.

For this series, the first letters are B(2), F(6), J(10) and N(14), each increasing by 4. The second letters are D(4), H(8), L(12) and P(16), also increasing by 4. The next first letter is 14 + 4 = 18, which is R, and the next second letter is 16 + 4 = 20, which is T. Thus RT is the pair that continues the uniform +4 progression in both positions.

Option A:
Option A is correct because both letters follow the established pattern of adding four positions. It places R after N and T after P, matching the arithmetic sequence. This preserves the symmetry between the first and second letters in the series.

Option B:
Option B, QS, has Q as the first letter, which is only 2 steps ahead of N, contradicting the +4 rule. Its second letter S is also only 2 steps beyond P. Since both gaps are too small, QS fails to maintain the consistent structure.

Option C:
Option C, RU, gives the correct first letter R but moves the second letter to U, which is 5 steps ahead of P. This breaks the equal step requirement for both letters. Because it inflates the second-letter increment, RU cannot be accepted.

Option D:
Option D, ST, advances the first letter to S, which is 5 positions ahead of N. This oversteps the observed increment and loses the alignment with the second letter’s movement. As a result, ST does not match the series rule.
