UGC NET Questions (Paper – 1)

Using the simple interest formula I = PRT/100, we substitute I = 600, R = 10 and T = 3 to get 600 = P × 10 × 3 / 100. This simplifies to 600 = 0.3P, so P = 600 ÷ 0.3 = 2000. Therefore, the principal amount on which interest is calculated is ₹2000.

Option A:
If the principal were ₹1500, then the interest at 10% per annum for 3 years would be 1500 × 10 × 3 / 100 = ₹450, which is less than the given interest of ₹600. Hence, this value does not satisfy the data in the problem.

Option B:
If the principal were ₹1800, simple interest at the given rate and time would be 1800 × 10 × 3 / 100 = ₹540. This again does not match the stated interest of ₹600, so this option is not correct.

Option C:
A principal of ₹2000 is correct because it produces the exact interest mentioned: 2000 × 10 × 3 / 100 = ₹600. This agreement confirms that ₹2000 is the initial amount invested or borrowed. In aptitude questions, carefully rearranging formulas like this is a common requirement.

Option D:
If the principal were ₹2200, the interest would be 2200 × 10 × 3 / 100 = ₹660, which exceeds the given value. This shows that ₹2200 cannot be the starting amount for this problem. Therefore, this option must be rejected.

Statements A, B and C are correct, whereas D is incorrect. A is true because intrapersonal communication includes self-reflection, internal dialogue and self-questioning used by learners and teachers. B is true since interpersonal communication commonly appears in counselling or mentoring sessions involving two people. C is true as group communication covers small group interactions aimed at a shared assignment or project. D is false because mass communication usually addresses large, dispersed audiences through media, not small face-to-face classroom groups.

Option A:
Option A lists A and B only and omits C, ignoring the important level of group communication relevant to educational teamwork. Although A and B are correct, leaving out C means the answer does not cover all the correct statements given. Therefore A and B only is incomplete and cannot be accepted.

Option B:
Option B includes B and C but leaves out A, failing to mention intrapersonal communication which is fundamental for self-reflection and self-regulation in learning. Since A is also a correct statement, restricting the set to B and C only underrepresents the full range of levels mentioned. Consequently this option is not correct.

Option C:
Option C correctly groups A, B and C and excludes D, which misdefines mass communication as a small face-to-face situation. By including all the true statements about intrapersonal, interpersonal and group communication and rejecting the false one, this option accurately reflects the levels of communication in education. Hence A, B and C only is the correct answer.

Option D:
Option D treats A, B, C and D as all correct, but D contradicts standard understanding of mass communication as a large-scale mediated process. Including D with the correct statements makes the combination internally inconsistent. For this reason, this option cannot be chosen.

Statements A and B correctly define validity and reliability. Statement D is true because objectivity reduces examiner subjectivity, and E is true because practicability concerns time, cost and feasibility. Statement C is false since a test can be valid and reliable yet still contain biased items, and F is false because validity and practicability are also important. Therefore, the correct set is A, B, D and E only, making option A the right answer.

Option A:
Option A includes A, B, D and E, which together describe essential attributes of effective classroom tests. Excluding C and F makes this set accurate. Hence A, B, D and E only is correct.

Option B:
Option B adds C, but C is false because fairness is not automatic even with validity and reliability. Therefore A, B, C and D only is not correct.

Option C:
Option C includes F (false) and omits reliability (B). Hence A, D, E and F only is not valid.

Option D:
Option D includes F (false) and omits validity (A). Therefore B, D, E and F only cannot be correct.

Option E includes C (false), so A, B, C, D and E only is invalid.

Option F includes C and F (both false) and omits A and B, so C, D, E and F only cannot be accepted.

Statements A, B, C and D describe central aspects of evaluation and policy research, and F adds an important methodological note. A is true because evaluation research systematically judges programme effectiveness, while B correctly notes that formative evaluation is conducted during implementation to improve it. C is accurate in defining summative evaluation as focusing on end results, and D properly characterises policy research as evidence-oriented. F is also true since both domains often combine qualitative and quantitative methods, whereas E is false because evaluation is not restricted to randomised trials or purely quantitative approaches.

Option A:
Option A omits statement F, thereby neglecting the fact that mixed-methods designs are common and useful in both evaluation and policy research. While A, B, C and D are correct, the absence of F leaves out an important contemporary practice. Hence, this option is incomplete.

Option B:
Option B includes B, C, D and F but leaves out A, ignoring the fundamental role of evaluation research in assessing programme effectiveness. Without A, the combination does not fully capture what evaluation research entails. Therefore it cannot be considered correct.

Option C:
Option C is correct because it lists A, B, C, D and F, providing a comprehensive and accurate picture of what these research types do and how they are conducted. It excludes E, which unjustifiably narrows evaluation research to one design and excludes qualitative data. This combination therefore contains all and only the true statements.

Option D:
Option D wrongly includes statement E and omits B, misrepresenting both the scope of evaluation methods and the concept of formative evaluation. Since it mixes a false statement with correct ones and overlooks a true statement, this option is not acceptable.

A curriculum that offers a major along with minors and diverse electives across disciplines embodies the philosophy of liberal education, which values breadth, flexibility and intellectual exploration. It aims at holistic development and critical thinking rather than narrow specialisation, so “liberal” is the correct descriptor.

Option A:
Option A is correct because liberal education explicitly encourages students to engage with multiple fields, integrate knowledge and design flexible study pathways, exactly as described in the stem.

Option B:
Option B is incorrect since “remedial” education focuses on removing basic learning deficits and is not defined by a broad elective-based curriculum.

Option C:
Option C is wrong because “vocational” education emphasises specific job skills and a focused, occupation-centred syllabus, not wide disciplinary choice across humanities, sciences and social sciences.

Option D:
Option D is incorrect as “purely rote” learning is based on memorisation and repetition, which is the opposite of the critical, reflective and multi-disciplinary engagement promoted by liberal education.

If A and B share profits in the ratio 7:9, the total number of parts is 7 + 9 = 16. Each part is worth ₹1,60,000 ÷ 16 = ₹10,000. A’s share is 7 × ₹10,000 = ₹70,000 and B’s share is 9 × ₹10,000 = ₹90,000. The difference between their shares is ₹90,000 − ₹70,000 = ₹20,000.

Option A:
Option A is correct because it directly reflects the difference between 7 parts and 9 parts when each part is ₹10,000. The arithmetic shows that the financial gap between A and B is exactly two parts, which equals ₹20,000. This fits both the total profit and the specified sharing ratio.

Option B:
Option B, ₹22,000, would not correspond to an integer number of ratio parts, given that each part is ₹10,000. It would imply a difference of 2.2 parts, which contradicts the whole-number nature of the ratio 7:9 and the discrete sharing of profit.

Option C:
Option C, ₹24,000, would amount to a difference of 2.4 parts, which again is inconsistent with the ratio 7:9. Using this figure would mean the implied total profit cannot be exactly ₹1,60,000 when aligned with the ratio.

Option D:
Option D, ₹25,000, suggests an even more irregular difference and would break the connection between the ratio parts and the fixed total profit. When we reverse-calculate, no whole-number ratio 7:9 with a total of 16 parts yields a difference of ₹25,000, so this option is impossible under the given conditions.

Statements A, B and D are correct and together explain the distinction between mitigation and adaptation. Mitigation is about reducing emissions, adaptation is about adjusting systems to cope with impacts and climate-resilient crops are a clear example of adaptation. Statement C is conceptually incorrect in this context because afforestation and tree planting as carbon sinks are typically classified as mitigation actions, although they may have some adaptive co-benefits. Hence, the combination that includes A, B and D only is the correct answer.

Option A:
Option A is incorrect because it includes A and B but omits D, which is also a correct example of adaptation. While A and B provide definitions, leaving out D means the option does not fully represent the set of correct statements requested. A complete answer must recognise a concrete adaptation example as well.

Option B:
Option B is incorrect because it groups B and D only, leaving out A. Although B and D are correct, A is also correct in defining mitigation, and the question asks for all correct statements. Excluding a valid definition of mitigation makes this combination incomplete.

Option C:
Option C is correct because it brings together the accurate definition of mitigation, the accurate definition of adaptation and a valid example of adaptation in the form of climate-resilient crops. It appropriately excludes C, which mislabels a typical mitigation measure as adaptation. By balancing conceptual clarity with relevant examples, this option best fits the question.

Option D:
Option D is incorrect because it treats all four statements A, B, C and D as correct. Since C misclassifies tree planting solely as adaptation, accepting it alongside the other statements blurs the important conceptual distinction between mitigation and adaptation. The presence of this incorrect statement invalidates the combination.

Kevalavyatireki inference obtains vyapti from observations that wherever the sadhya is absent, the hetu is also absent, without finding any positive instance of their co-presence. The relation is thus supported solely by negative concomitance. Nyaya treats this as a distinctive pattern of inferential support. Therefore the type of inference mentioned in the stem is kevalavyatireki.

Option A:
Option A, kevalanvayi, depends exclusively on positive instances and does not appeal to joint absences, making it structurally different from what is described.

Option B:
Option B, anvayavyatireki, integrates both affirmative and negative cases and is more inclusive than the purely negative evidence scenario here.

Option C:
Option C, purvavat, classifies inference by its cause-to-effect temporal direction rather than by the pattern of positive or negative instances used to establish vyapti.

Option D:
Option D is correct because kevalavyatireki literally means "only by negative concomitance" and is defined in Nyaya precisely in terms of reliance on shared absences for establishing the universal relation.

Statements A, B, C, D and E correctly describe core equivalence laws of propositional logic, while F is false. Double negation, De Morgan’s laws, the implication law and distributivity are all standard tools for simplifying or transforming statements. In reasoning questions, these equivalences can be applied implicitly even if symbolic notation is not shown. F is wrong because such simplifications are central to many exam solutions. Thus A, B, C, D and E only is the correct combination.

Option A:
Option A is incomplete since it omits E, leaving out the distributive law, which is also a recognised equivalence. While A, B, C and D are all true, the absence of E means one important law is missing. Therefore this option does not capture the full set of correct statements.

Option B:
Option B is wrong because it includes F, which asserts that these equivalences are never used in UGC NET reasoning. In practice, many items rely on them, even if test-takers apply them informally. Including F therefore makes the overall combination incorrect.

Option C:
Option C is incorrect since it omits A and retains only B, C, D and E. Without A, the crucial principle of double negation is missing, which is a basic equivalence often taught alongside the others. This omission prevents the option from representing all true statements.

Option D:
Option D is correct as it brings together all five valid equivalences and excludes the single false statement. It accurately reflects how formal logic simplifies complex expressions and how those ideas underlie exam questions. Hence it is the right answer.

Debriefing is an ethical step taken after participants have completed their involvement in a study, especially when deception or incomplete disclosure was used. During debriefing, researchers explain the true purpose of the research, clarify any misleading information and answer participants’ questions. This helps restore trust and ensures that participants leave without misconceptions or distress. Because the stem refers to providing a full explanation of the true purpose after participation, debriefing is the correct term.

Option A:
Anonymity concerns whether researchers can link responses to individual identities and is not about post-study explanations. While both relate to ethics, anonymity does not describe the process mentioned in the question.

Option B:
Confidentiality focuses on protecting participants’ personal information from being disclosed to others, not on giving explanations after the study. Therefore, confidentiality is not the appropriate completion here.

Option C:
Briefing typically refers to giving initial instructions or information before a study or task, which is the opposite temporal sequence to what the stem describes. Since the question is about explanations given after participation, briefing is not correct.

Option D:
Debriefing allows participants to understand why certain procedures were used, including any necessary deception, and offers them an opportunity to withdraw their data if they feel uncomfortable. This process upholds respect for persons and aligns exactly with the description in the stem.

Curriculum decolonisation involves challenging colonial-era biases in knowledge systems and incorporating perspectives, texts and methodologies from indigenous and marginalised communities. The stem describes re-examining Eurocentric syllabi and including indigenous knowledge, which is at the heart of decolonisation debates. Therefore, “decolonisation” correctly fills the blank, making Option B the appropriate answer.

Option A:
Depoliticisation would mean removing political content or analysis, whereas decolonisation debates are explicitly critical and political in nature. Therefore, Option A is incorrect.

Option B:
Option B is correct because the described rebalancing of knowledge systems and inclusion of indigenous perspectives is precisely what “curriculum decolonisation” refers to.

Option C:
Militarisation refers to increased influence of military values/structures and is unrelated to syllabus content debates about colonial legacies. Hence, Option C is incorrect.

Option D:
Mechanisation concerns technology and machines and does not address whose knowledge is valued or how colonial power shaped curricula. The stem is about epistemic justice and representation, not automation. Therefore, Option D is incorrect.

Cloud storage providers allocate space on networked servers and present it to users as if it were a drive accessible from many devices. Data stored there can be synchronised, shared and backed up automatically. This model reduces dependence on specific physical devices and supports collaboration. Therefore the services mentioned are instances of cloud storage.

Option A:
Option A, optical media, includes CDs and DVDs that are physical discs and require local drives; they are not internet-based services.

Option B:
Option B, removable storage, refers to USB drives or external disks that are attached directly to computers and do not inherently offer remote, multi-device access.

Option C:
Option C is correct because cloud storage explicitly denotes online file-hosting services where infrastructure is managed by third-party providers and users connect over the internet. The examples given in the stem are among the most widely used cloud storage platforms.

Option D:
Option D, local area storage, is not a standard term in cloud computing and suggests on-premises storage within a network rather than externally hosted services.

Drstanta is the illustrative example employed to make the vyapti between hetu and sadhya clear to the listener. By pointing to a well-known case where the same relation holds, such as smoke and fire in a kitchen, the speaker strengthens confidence in the general rule. This example plays a pedagogical role in the five-membered inference. Therefore the familiar instance described in the stem is called drstanta.

Option A:
Option A, vyapti, is the universal concomitance itself, not the particular instance chosen to display it. The drstanta is used to convey vyapti but is conceptually distinct from it.

Option B:
Option B, sadhya, is the probandum to be established in the paksha, such as "fiery", and is not an example case at all.

Option C:
Option C is correct because drstanta literally means "seen instance" and is explicitly defined in Nyaya as the member of inference that supplies a concrete illustration of the general rule.

Option D:
Option D, hetvabhasa, denotes a fallacious reason and has no role in providing supportive examples; rather, it signals a defect in reasoning.

Urban heat islands occur when built-up surfaces absorb and re-radiate more heat than vegetated rural landscapes. Concrete, asphalt and buildings store heat, while reduced vegetation lowers cooling from evapotranspiration. Waste heat from vehicles, air-conditioners and industry further raises temperatures. As a result, cities are often several degrees warmer than nearby rural areas, especially at night, which matches the description in option B.

Option A:
Option A is incorrect since it reverses the observed pattern; rural areas are generally cooler, not warmer, at night. Their vegetation and open spaces allow more rapid cooling.

Option B:
Option B is correct because it identifies both the temperature difference and the main causes. It links warmer cities to material properties and anthropogenic heat, which is how climatologists define urban heat islands.

Option C:
Option C is incorrect because tall buildings can also trap heat and reduce wind flow. Shade helps in the daytime, but overall urban form still tends to raise average temperatures.

Option D:
Option D is incorrect as rainfall patterns are influenced by many factors. Population density alone does not explain the heat island effect, which is specifically about temperature.

Mass communication involves institutional sources sending messages through technological channels to large,heterogeneous and dispersed audiences. A news channel broadcasting election results fits all these features. The audience includes many unknown viewers across the country. Hence mass communication is the correct term.

Option A:
Interpersonal communication involves few participants and usually face to face contact,which is absent here.

Option B:
Mass communication is one-to-many,mediated through TV/technology,and reaches a large dispersed audience,so election-result broadcasting fits it.

Option C:
Group communication refers to small coordinated discussions,rather than national broadcasts.

Option D:
Organisational communication concerns internal interactions within an institution,not public media messages.
