UGC NET Questions (Paper – 1)

Statements A, C, D and E describe key features of three-set Venn diagrams. A is correct because three sets generate 2³ = 8 possible membership combinations. C is true as the triple intersection appears where all three circles overlap. D correctly states that the union collects elements belonging to at least one of the sets. E is also correct in survey contexts where the region outside all circles stands for those having none of the properties. B is false since “A only” must exclude elements that also belong to B or C, so the correct combination is A, C, D and E only.

Option A:
Option A is correct because it gathers all the true statements and excludes B, which misdefines the “A only” region by including members of B and C. It captures the structure and interpretation of three-set Venn diagrams used in survey and counting questions.

Option B:
Option B is incomplete as it omits E, ignoring the important role of the outside region for respondents with none of the attributes. Without E, the account of all regions relevant to survey interpretation is not comprehensive.

Option C:
Option C is incorrect because it includes B along with A, C and D, thereby accepting the wrong description of “A only”. Even one incorrect statement within the combination makes the whole option invalid.

Option D:
Option D is wrong as it features B and therefore carries forward the same misunderstanding of exclusive regions, while also omitting A, which states the basic partitioning into eight regions. This mix of omission and error makes the option unsuitable.

Statements A, B and C correctly explain common ICT abbreviations, while statement D is incorrect. URL, HTML and IP address are standard terms related to web addressing, markup and logical identification of devices. ISP actually stands for Internet Service Provider, not Internet Service Password. Therefore, the set of correct statements consists of A, B and C only.

Option A:
Option A is correct because it includes precisely the three true statements and excludes D. It aligns with widely accepted definitions of URL, HTML and IP address. By not accepting the wrong expansion of ISP in statement D, this option remains factually accurate.

Option B:
Option B is incorrect because it lists only A and B as correct, leaving out C. Statement C is also true, since IP addresses uniquely identify devices at the logical level. Any correct answer must include all three true statements.

Option C:
Option C is incorrect because it groups B, C and D as correct. While B and C are accurate, D is wrong, as ISP does not stand for Internet Service Password. Including a false statement invalidates this combination.

Option D:
Option D is incorrect because it accepts all four statements as correct, thus endorsing the incorrect explanation of ISP in D. A valid answer must exclude that misdefinition.

Each term after the first is obtained by doubling the previous term and subtracting 2. We see 3 × 2 − 2 = 4, 4 × 2 − 2 = 6, 6 × 2 − 2 = 10, 10 × 2 − 2 = 18 and 18 × 2 − 2 = 34. Applying the same rule to 34 yields 34 × 2 − 2 = 68 − 2 = 66. This keeps the recursive structure intact.

Option A:
Option A gives 62, which would correspond to subtracting 6 after doubling 34 and introduces a new constant that does not appear in earlier steps. Thus, 62 is not consistent with the recursive rule.

Option B:
Option B offers 64, equal to 34 × 2 − 4, which again changes the subtractive constant and conflicts with the uniform "minus 2" operation. Therefore, 64 cannot be accepted as correct.

Option C:
Option C yields 66, exactly equal to 34 × 2 − 2, and fits the observed pattern at every stage. The series 3, 4, 6, 10, 18, 34, 66 remains governed by a single clear transformation. Hence, 66 is the correct next term.

Option D:
Option D suggests 68, which is simply 34 × 2 and omits the subtraction of 2 found throughout the series. This breaks the rule that defines the sequence. Therefore, 68 is not appropriate.

A common convention in CBCS-based regulations is that one credit for practical or laboratory work corresponds to about two hours of lab engagement per week. This recognises that practical classes often require more time for set-up and hands-on work than lecture hours. The stem refers specifically to credit equivalence for practical work, and “two” hours is the widely used norm in many universities. Hence, Option C is the best answer.

Option A:
Half an hour per week would be far too little to justify one full credit of practical learning and does not reflect actual practice. Therefore, Option A is not reasonable in the context of higher education norms.

Option B:
One and a half hours might be used in some alternative schemes, but the commonly cited CBCS norm for practicals is two hours per credit. Thus, Option B is less accurate than Option C.

Option C:
Option C is correct because (in many CBCS implementations) 1 practical credit is conventionally mapped to around 2 laboratory contact hours per week.

Option D:
Allocating five hours of laboratory work to a single credit would distort the balance between practical and theory courses in students’ overall workload and is rarely used in CBCS norms. Therefore, Option D is incorrect.

Statements A, C and D correctly indicate how ICT supports higher education. Statement A is true because ICT tools allow blending classroom instruction with online components. Statement C is correct since Learning Management Systems help deliver content, monitor learner progress and enable communication between teachers and students. Statement D is also true as ICT facilitates flexible and lifelong learning through online courses and open educational resources, while statement B is false because digital divides and resource constraints prevent automatic equal access.

Option A:
Option A is incorrect because it includes only A and C and omits D. Flexible and lifelong learning opportunities are a major advantage of ICT in higher education, and excluding D leaves out this important dimension.

Option B:
Option B is correct because it combines A, C and D, presenting a rounded view of ICT’s role in blended learning, course management and lifelong learning. By excluding B, it recognises that structural inequalities limit equal access despite ICT’s potential. This makes it the only fully accurate option.

Option C:
Option C is incorrect because it includes statement B along with C and D. While C and D are true, B wrongly asserts automatic equality of access through ICT, ignoring disparities in connectivity and devices. Hence this combination cannot be accepted.

Option D:
Option D is incorrect because it selects A, B and D and drops C. Leaving out the central role of Learning Management Systems weakens the description, and including B imports the incorrect assumption of automatic equal access.

Sustainable consumption aims to reduce the environmental impact of goods and services over their life cycle. Choosing durable products and repairing them extends their useful life and lowers the demand for new production. This reduces resource extraction, energy use and waste generation associated with manufacturing and disposal. Therefore, the practice of using and repairing long-lasting items is a clear example of sustainable consumption.

Option A:
Option A is correct because it embodies the principles of reduce and reuse. Households that maintain and repair products generate less waste, save money and lower their ecological footprint, aligning daily choices with sustainability goals.

Option B:
Option B is incorrect since leaving lights and fans on wastes electricity and increases emissions from power generation. It contradicts the idea of conserving energy at home.

Option C:
Option C is incorrect because throwing away edible food increases solid waste and squanders the resources used to produce and transport that food. Sustainable consumption would encourage better planning, storage or sharing to avoid food waste.

Option D:
Option D is incorrect as buying heavily packaged products for appearance leads to unnecessary material use and waste. Sustainable consumers typically prefer minimal or recyclable packaging.

Statement C is the only wrong statement because even with digital payment systems, robust cybersecurity measures remain essential. UPI does support instant mobile-based transfers, digital wallets store card details or balances and PoS terminals accept card and mobile payments, so A, B and D are correct. Cyberattacks, fraud and phishing continue to be threats, so it is misleading to say that cybersecurity is no longer needed. Hence the option that selects only C as wrong is correct.

Option A:
Option A is incorrect because it treats both A and C as wrong statements. Statement A is accurate and describes a core feature of UPI as used in India. Grouping a true statement with a false one makes this combination invalid.

Option B:
Option B is correct because it isolates C as the single wrong statement and implicitly accepts A, B and D as correct. It reflects the reality that digital payment systems still require encryption, authentication and user awareness for safe use.

Option C:
Option C is incorrect because it considers both C and D as wrong. While C is false, D correctly recognises that PoS terminals support card and mobile-based payments. Including a true statement in the wrong set makes the option unacceptable.

Option D:
Option D is incorrect because it takes B and C as wrong statements. B is true since digital wallets commonly store card details or balances for easy transactions. Combining this true statement with the false claim in C produces a logically inconsistent option.

Accreditation is the process through which an external quality assurance agency evaluates an institution or programme against predefined criteria and standards. When the institution meets these standards, it receives an accreditation status or grade. The stem describes exactly this type of external evaluation and formal certification, which is correctly called accreditation. Thus, Option B is the appropriate answer.

Option A:
Affiliation is a relationship between a university and its colleges, where the university governs examinations and awards degrees. While important administratively, it is not the same as a quality certification process, so Option A is not correct.

Option B:
“Accreditation” is the recognised term for external evaluation and formal recognition of quality standards, so it matches the stem exactly.

Option C:
Adjudication usually refers to legal decision-making by a court or tribunal rather than to educational quality assurance processes. Therefore, Option C does not match the context of the question.

Option D:
A birth certificate confirms an individual’s existence and identity, not the quality of an educational institution. It is issued by civil administration authorities rather than by academic quality bodies. Consequently, “certification of birth” is conceptually misplaced and does not describe the process in the stem.

Statement A matches the definition of percentage as a ratio per hundred. C is correct because a 25% profit implies selling price equals cost price plus 25% of cost, giving 125% of cost. D is true since equal ratios constitute a proportion. E is also correct; if a:b = 2:3, reversing gives b:a = 3:2. B is false, because a 20% increase followed by a 20% decrease results in a net 4% decrease. Thus A, C, D and E only form the correct set.

Option A:
Option A is incomplete; while A and C are true, omitting D and E ignores important proportional and inverse ratio relationships frequently examined in NET aptitude questions.

Option B:
Option B is wrong as it includes B, which misstates the effect of successive percentage changes, and so mixes a false statement with correct ones.

Option C:
Option C is correct because it collects the accurate definitions and interpretations of percentage, profit, proportion and inverse ratio, while excluding B, which leads to a typical exam trap.

Option D:
Option D is incorrect because it includes B, allowing a false claim about successive percentage operations into the option, even though C, D and E are correct.

Statements A, C and D are correct, while B and E are incorrect. A is true as cultural background shapes meanings attached to words and behaviours. C is true because inclusive examples help learners relate content to their own contexts. D is true since recognising language diversity and adjusting communication is central to intercultural competence. B is false because assuming identical norms ignores diversity, and E is false because higher education also hosts culturally diverse populations. Therefore, A, C and D only is the correct combination.

Option A:
Option A lists A and C only, both accurate, but omits D, which rightly emphasises language diversity as part of intercultural competence. Without D, the answer does not capture all correct statements, so A and C only is incomplete.

Option B:
Option B brings together A, C and D, capturing interpretive differences, inclusive examples and language sensitivity, and excludes B and E, which minimise or ignore diversity. Since it contains all and only the true statements, A, C and D only is the correct option.

Option C:
Option C includes C and D but leaves out A, failing to state the core idea that messages are interpreted differently across cultures. As this is fundamental to intercultural communication, C and D only cannot be the best answer.

Option D:
Option D adds E to A, C and D, but E incorrectly claims that intercultural concerns are irrelevant in higher education. Including E creates a mixture of true and false statements, so A, C, D and E only is invalid.

The NCQG negotiated at COP29 seeks to move beyond the earlier USD 100 billion target by setting a higher, time-bound ambition. It aims to scale climate finance to roughly USD 300 billion a year for developing countries by 2035, reflecting rising needs for mitigation and adaptation. Developed countries are expected to lead, consistent with the principle of common but differentiated responsibilities. The goal is also meant to be revisited over time as science and needs evolve. (Drishti IAS)

Option A:
This option correctly conveys both the approximate magnitude (tripling) and the timeframe (by around 2035) of the NCQG, as well as its focus on developing countries and leadership role for developed nations. It aligns with reported summaries of COP29 outcomes on finance and thus is the best current-affairs-based answer.

Option B:
Completely ending public climate finance was not an option under serious discussion. Public finance remains crucial for adaptation and for leveraging private investment, especially in vulnerable countries. This statement contradicts the equity-oriented spirit of the NCQG negotiations.

Option C:
Restricting climate finance only to mitigation projects in developed countries runs against the idea that finance should flow to developing countries and cover both mitigation and adaptation. It therefore misstates the direction and scope of the agreed goal.

Option D:
Freezing finance permanently at USD 100 billion would ignore the growth in needs documented by various assessments and contradict calls for higher support. COP29’s objective was to go beyond, not lock in, the earlier 100-billion pledge.

Statements A, C and D correctly describe data storage units in the binary system used in many ICT contexts. Kilobyte is commonly approximated as 1024 bytes when referring to memory, and a gigabyte is conventionally treated as 1024 megabytes in the same binary sense. A bit is indeed the smallest unit of data in a computer. Statement B is wrong because one megabyte is smaller, not larger, than one gigabyte, so the correct set of true statements is A, C and D only.

Option A:
Option A is incorrect because it includes only statements A and C while omitting D. Statement D is also true, as one gigabyte is usually taken as 1024 megabytes when using binary-based measurement. Excluding a true statement leads to an incomplete identification of correct statements.

Option B:
Option B is correct because it groups exactly the true statements A, C and D. Together they explain the hierarchical relationship between bit, byte, kilobyte, megabyte and gigabyte in ICT. No false statement is included in this combination, which matches the requirement to select all correct statements.

Option C:
Option C is incorrect because it includes B, C and D as correct. While C and D are true, statement B is false since an MB is smaller than a GB. Incorporating a false statement into the combination means this option cannot be accepted.

Option D:
Option D is incorrect because it assumes that all four statements are correct. Statement B incorrectly reverses the size relationship between megabyte and gigabyte. Since a single false statement is enough to disqualify the combination, this option is not correct.

Mode 2 knowledge refers to research conducted in the context of application, involving multiple disciplines and various social actors. It emphasises problem solving and practical relevance beyond traditional academic boundaries. The stem lists these characteristics, so the correct number is “2.”

Option A:
Mode 0 is not a recognised category in discussions of knowledge production and has no established meaning. Therefore, this option cannot complete the term.

Option B:
Mode 1 denotes traditional disciplinary, curiosity-driven research carried out mainly within universities. It does not highlight the transdisciplinary and socially distributed nature mentioned in the question, making this option unsuitable.

Option C:
Mode 2 captures the shift towards context-driven, application-oriented and collaborative knowledge production outlined in the stem, confirming that this option is correct.

Option D:
Mode 4 is not part of the classic Mode 1–Mode 2 typology and does not refer to the described pattern of research. Hence, this option is incorrect.

NEP 2020 envisages IITI as an institute to build capacity in translation and interpretation across Indian and foreign languages and to support materials and expertise for multilingual education.

Option A:
Option A is incorrect because engineering skills are addressed by technical institutions, not by IITI.

Option B:
Option B is correct as it directly states the translation and interpretation functions linked to language policy that NEP assigns to IITI.

Option C:
Option C is wrong since sports coaching is unrelated to IITI’s language and translation mandate.

Option D:
Option D is incorrect because a film acting school does not correspond to the academic and linguistic role described for IITI in the policy.

Resource limits refer to the finite nature of land,water,energy and other ecological assets that support human life. The stem talks about a limit to the number of people Earth can support based on these resources. This is essentially an illustration of resource limits and planetary constraints. Therefore “limits” fits the blank correctly.

Option A:
Abundance suggests resources are more than sufficient,which contradicts the idea that Earth can support only a limited number of people.

Option B:
Limits emphasise that indefinite growth is not possible on a finite planet and directly matches the meaning in the stem.

Option C:
Entropy is a thermodynamics concept and is not the straightforward term used here for population–resource constraints.

Option D:
Privatisation is about ownership/management,not biophysical constraints on how many people can be supported.
