UGC NET Questions (Paper – 1)

Solar pumps allow farmers to access irrigation without relying solely on diesel or often-unreliable grid connections. This can lower operating costs, reduce local pollution and improve the predictability of water supply. When combined with appropriate groundwater management, such systems enhance both livelihoods and environmental outcomes. The record installation therefore illustrates how renewable technologies can simultaneously support rural development and climate goals.

Option A:
This option is incorrect because solar pumps are specifically designed to reduce diesel dependence. Replacing diesel sets with solar is a key objective of schemes like PM-KUSUM.

Option B:
This option correctly identifies the main developmental and environmental advantages of large-scale solar pump deployment. It recognises the potential for higher and more stable farm incomes alongside lower fossil fuel use and emissions.

Option C:
Transmission losses relate to grid-supplied power; decentralised solar pumps actually reduce the need for long rural feeders, potentially easing grid burdens. Therefore, this option misreads the impact of decentralised renewable systems.

Option D:
Groundwater conservation depends on overall water governance, cropping patterns and regulation. Solar pumps can be integrated into sustainable groundwater management; they do not automatically make conservation impossible, though safeguards are needed.

Statements A, C, D and F correctly represent contemporary views of teaching as purposeful, creative, interactive and reflective. A is true because teaching intentionally targets changes in knowledge, skills and attitudes. C is true as teaching requires both intuitive artistry and scientific planning. D is true since teaching always involves interaction among teacher, learners and content, and F is true because teachers must reflect and adjust to improve. B is false because learner needs and interests are central to good teaching, and E is false because modern pedagogy considers learners as active participants; therefore A, C, D and F only is the correct combination.

Option A:
Option A selects A, C and D, all of which are true, but it omits F, which correctly states the need for continuous reflection. Because one true statement is missing, this combination does not represent the full set of correct statements.

Option B:
Option B includes A, C, D and F, bringing together all the true statements about planning, art–science balance, social interaction and reflection. It excludes B and E, which wrongly portray teaching as mere information telling and learners as passive. Hence A, C, D and F only is the correct option.

Option C:
Option C adds B to C, D and F, but B incorrectly claims that teaching ignores learner needs and interests. Including this false statement makes the combination inconsistent with learner-centred teaching, so B, C, D and F only is not correct.

Option D:
Option D treats all six statements A, B, C, D, E and F as correct, but B and E conflict with contemporary views that emphasise learner needs and active participation. Because it fails to distinguish correct from incorrect statements, this option is wrong.

Statements A, B and E present the developmental role of evaluation. A is true because results indicate where additional explanation or support is required. B is true as ongoing assessment data can guide teachers in adjusting methods while a course is in progress. E is true since sharing criteria clarifies expectations and supports fairness and self-assessment. C is false because student feedback is a valuable source of information for teacher growth, and D is false because continuous and formative assessments also provide insights for improvement. Thus A, B and E only is the correct combination.

Option A:
Option A includes A and B but omits E, missing the important point that transparency in criteria is part of using evaluation constructively. The absence of E makes the set incomplete.

Option B:
Option B lists B and E but leaves out A, which emphasises using evaluation to locate areas of student difficulty. Without A, the picture of how evaluation informs support is partial.

Option C:
Option C groups A, B and C and treats C as correct, even though dismissing student feedback contradicts reflective teaching practice. Including a false statement makes this combination invalid.

Option D:
Option D combines A, B and E, all of which show how evaluation can feed back into teaching and learning. It excludes the two false statements C and D that deny the value of feedback and formative assessments. Therefore A, B and E only is the correct option.

Option E adds C and D to A and E, but both C and D undervalue important sources and forms of evaluation. Their inclusion makes A, C, D and E only an incorrect answer.

Statements A, B, D and E correctly describe quality regulation in distance education. A is true because regulatory approval is required for HEIs to offer degrees by distance mode. B is true as regulators insist on comparable learning outcomes across modes. D is true since quality ODL systems rely on ICT-based learner support. E is true because unapproved programmes risk non-recognition. C is false because counselling and support are essential in ODL, and F is false because credible assessment remains necessary even in distance mode.

Option A:
Option A is correct as it includes all four accurate statements on approval, parity, ICT support and recognition, and excludes C and F, which incorrectly remove learner support and assessment requirements.

Option B:
Option B is incorrect because it adds C, accepting the false claim that distance learners do not need support services.

Option C:
Option C is incorrect because it includes F, which dismisses the need for credible assessment, and omits A, so it fails to mention the basic requirement of regulatory approval.

Option D:
Option D is incorrect because it contains both C and F, thereby eliminating learner support and assessment, and thus contradicts quality assurance principles.

NEP 2020 recommends creating a Gender Inclusion Fund to focus on the education of girls and transgender persons. The fund is meant to support state-level interventions, infrastructure, scholarships and safety measures. It targets those most likely to be left behind. The fund is a key equity instrument.

Option A:
Funding only boys’ hostels would contradict the gender inclusion objective and is not mentioned.

Option B:
This option correctly captures the idea that the fund is aimed at removing barriers faced by girls and transgender learners.

Option C:
Advertising for private schools is not an appropriate use of public inclusion funds.

Option D:
Paying corporate salaries is unrelated to educational inclusion.

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.
