UGC NET Questions (Paper – 1)

Carbon credits are units created when a project or activity demonstrably reduces or removes greenhouse gas emissions compared to a baseline. Each credit corresponds to a specific quantity, often one tonne of CO₂ equivalent, and can be traded and used for compliance in emissions trading schemes.

Option A:
Option A is incorrect because credits reward emission reductions, not fossil fuel production; fossil fuel subsidies undermine mitigation goals.

Option B:
Option B is correct as it emphasises both the tradable nature and the quantified emission reduction or removal that a credit represents.

Option C:
Option C is incorrect since a tax on renewable energy would discourage clean energy and is unrelated to the concept of credits.

Option D:
Option D is incorrect because credits exist within capped or regulated systems and do not give unlimited permission to pollute; entities must hold enough credits to match their emissions.

Statement (A) correctly describes teaching as a purposeful activity that brings desirable changes in learner behaviour, so it is not a wrong statement. Statement (B) is wrong because teaching is broader than training and cannot be reduced only to drill-based skill formation. Statement (C) is correct as teaching involves both creative, intuitive elements and systematic, scientific planning. Statement (D) is wrong since modern teaching emphasises learners' needs, interests and active participation rather than mere information transmission, so the wrong statements are B and D only.

Option A:
Option A assumes that only statement B is wrong and treats D as acceptable. However statement D reduces teaching to one-way transmission of information without considering learner needs, which contradicts learner-centred pedagogy. By ignoring the error in D, this option fails to include all wrong statements and is therefore incorrect.

Option B:
Option B correctly groups together statements B and D, both of which misrepresent the nature and objectives of teaching. B equates teaching with narrow drill-based training, while D ignores the centrality of learner needs and interaction. Because it includes both wrong statements and excludes the correct statements A and C, this combination accurately identifies the wrong statements.

Option C:
Option C treats A, B and D as wrong, but statement A is actually a sound definition of teaching as a purposeful activity producing desirable change in learners. Including A among the wrong statements shows confusion about the intended outcomes of teaching. As it wrongly labels a correct statement as wrong, this combination cannot be accepted.

Option D:
Option D declares that all four statements A, B, C and D are wrong. In reality A and C clearly express widely accepted views of teaching as purposive and as both an art and a science. By wrongly grouping these valid statements with the incorrect ones, the option overgeneralises and becomes an incorrect choice.

A sampling frame is a practical list or representation of all units in the population that can potentially be selected for the sample, such as a roster of students or a registry of schools. It operationalises the population for sampling purposes. The quality of the sampling frame strongly affects the representativeness of the sample. Because the stem describes a complete list of sampling units from which the sample is drawn, sampling frame is the correct term.

Option A:
Population denotes the entire set of individuals or units to which the researcher wishes to generalise findings, but it may exist conceptually without a concrete list. A sampling frame is a specific listing used to select sample elements. Therefore, population does not precisely match the stem’s description.

Option B:
A sample is the subset of units actually selected from the sampling frame for study, not the list from which they are chosen. The stem focuses on the list itself, so sample is not the right completion.

Option C:
Sampling frames are crucial for probability sampling, as they determine whether every population element has a known chance of selection. Incomplete or biased frames can lead to coverage error. This role corresponds exactly to the description in the question, confirming sampling frame as the appropriate answer.

Option D:
Cluster refers to naturally occurring groupings within the population, such as schools or villages, which may be sampled in cluster sampling designs. It is not the same as the comprehensive list of units used in selection. Hence, cluster is not the correct term here.

Statement E is the only wrong statement in this list. A is correct because induction proofs typically start by verifying the statement for the first natural number in the domain. B is correct since the induction step assumes P(k) and proves P(k+1). C correctly states that if the base and step are valid, the result holds for all relevant n. D is true because induction is a method for proving infinitely many cases using a finite argument. E is false because without proving the base case, there is no guarantee that the chain of implications starts, so the induction proof is incomplete.

Option A:
Option A is incorrect since it claims A alone is wrong, but A accurately describes the base step of induction. Declaring it wrong contradicts standard textbook presentations.

Option B:
Option B is wrong because it treats both A and E as wrong. While E is indeed incorrect, A is a true description of the base case and so cannot be grouped with E as wrong.

Option C:
Option C is correct because it singles out E, which wrongly dismisses the need for a base case, as the only incorrect statement. The other statements together present a coherent picture of mathematical induction.

Option D:
Option D is incorrect because it adds A and C to E in the set of wrong statements. C is a true summary of the outcome of induction, and A correctly describes the base step, so this option misclassifies several true statements as wrong.

Wiki-based environments provide simple editing interfaces so that multiple users can add, modify and link content pages. The revision history ensures transparency and allows rollback of problematic edits. This collaborative model supports collective knowledge construction and continuous updating of information. Thus sites such as Wikipedia exemplify wiki-based collaborative environments.

Option A:
Option A, static publishing, implies content managed only by a few administrators and rarely updated, which contrasts with the dynamic, user-edited nature of wikis.

Option B:
Option B, one way broadcasting, suggests information flowing from a single source to many receivers without their participation in content creation. Wikis are intentionally designed to be many-to-many rather than one-to-many.

Option C:
Option C, closed proprietary, would restrict editing rights and code access, whereas many wikis encourage broad participation and often rely on open technologies.

Option D:
Option D is correct because wikis are defined precisely as web systems enabling collaborative editing of linked pages, and the description in the stem fits this definition.

Statements A and B express the core idea of sustainable development, which is to balance economic growth with environmental protection and social equity while meeting present needs without compromising the ability of future generations. Statement C is incorrect because sustainable development does not reject technological innovation; instead, it promotes cleaner and more efficient technologies. Statement D is incorrect because sustainable development discourages over-exploitation of resources and promotes their prudent use. Therefore, the only correct combination of statements is A and B.

Option A:
Option A is correct because it includes statements A and B, both of which accurately define sustainable development as a balance among economic, environmental and social dimensions and emphasise intergenerational equity. Neither of these statements contains any exaggeration or contradiction with accepted definitions used in policy documents and UGC NET syllabus. Since statements C and D are false, excluding them makes this combination fully correct.

Option B:
Option B is incorrect because it adds statement C to the otherwise correct pair A and B. Statement C wrongly suggests that sustainable development rejects technological innovation, whereas in reality sustainable development encourages innovations such as renewable energy, cleaner production and eco-friendly technologies. Including an incorrect statement makes the whole combination wrong.

Option C:
Option C is incorrect because it combines B, C and D. Although statement B is correct, statements C and D are both incorrect. Statement C misrepresents the role of technology, and statement D promotes over-exploitation of resources, which is against the principle of sustainability. Due to the presence of these false statements, the combination cannot be correct.

Option D:
Option D is incorrect because it includes all four statements A, B, C and D. While A and B are true, C and D contradict the very idea of sustainable development by rejecting technological solutions and encouraging overuse of resources. A correct combination must exclude false statements, so selecting all four statements leads to an incorrect answer.

Statements A, B and D correctly capture key ideas about teaching aids. A is true because aids help concretise abstract ideas and support understanding. B is true as the selection of aids should follow from objectives and learner characteristics rather than habit. D is true since improvised, low-cost local materials can be highly effective when used thoughtfully. C is false because using unrelated aids can distract learners, and E is false because aids can support learning in all subjects, including languages and social sciences. Therefore A, B and D only is the correct combination.

Option A:
Option A groups together A, B and D, all of which represent sound principles for choosing and using teaching aids. It excludes C and E, which either promote irrelevant use or restrict aids to a few subjects. Hence A, B and D only is the right answer.

Option B:
Option B lists A and B but omits D, ignoring the importance of low-cost and local materials that are often most accessible to teachers. The absence of D makes the description incomplete.

Option C:
Option C combines A, C and D and treats C as correct, even though using aids that do not relate to the content can confuse or bore learners. Because it includes a false statement, this option is invalid.

Option D:
Option D groups B, D and E, but E incorrectly suggests that only certain subjects benefit from teaching aids. Including E undermines the option’s correctness.

Option E adds C to an otherwise correct set of A, B and D and thereby adopts the misleading idea that aids should be used even when irrelevant. This mixture of correct and incorrect statements makes A, B, C and D only unacceptable.

In hexadecimal, the digit F represents decimal value 15. The binary representation of 15 uses four bits all set to 1, because 15 = 8 + 4 + 2 + 1. Therefore, the correct 4-bit binary equivalent of F is 1111₂.

Option A:
Option A, 1101₂, equals 8 + 4 + 0 + 1 = 13, which is less than 15. It does not fully represent the hex digit F.

Option B:
Option B, 1110₂, equals 8 + 4 + 2 + 0 = 14. It is still smaller than 15 and misses the 1's place value.

Option C:
Option C, 1100₂, sums to 8 + 4 = 12 and is even further from 15. It lacks both the 2's and 1's contributions.

Option D:
Option D is correct because 1111₂ sums all four available place values 8, 4, 2 and 1, giving 15. This exactly matches the value of F in hexadecimal.

Statement B is the only wrong statement in this group. A is correct because data sufficiency focuses on whether information is enough, not on computing the final number. C is true since some questions are solvable with one statement but not with the other alone. D is also correct because in some cases, even combining statements fails to give a unique answer. E is correct since we generally presume the given data are consistent unless told otherwise. B is false because two insufficient statements may remain insufficient when combined.

Option A:
Option A is incorrect as it treats both A and B as wrong, even though A accurately states the objective in data sufficiency problems. Misclassifying A makes the option invalid.

Option B:
Option B is correct because it isolates B as the sole incorrect statement, capturing the fact that insufficiency of each statement alone does not guarantee sufficiency when combined.

Option C:
Option C is wrong because it wrongly marks C as wrong as well, even though C describes a common situation where one statement alone can be sufficient.

Option D:
Option D is incorrect since it ignores B altogether and claims only C and D are wrong, even though D and C correctly describe typical sufficiency patterns and B is the problematic rule.

The All India Council for Technical Education is the apex statutory body for technical education in India. It is charged with planning, coordinating and regulating standards in technical and management institutions, including engineering colleges and polytechnics. It grants approvals for starting new programmes, increasing intake and establishing new institutes. Because the question focuses on the body for proper planning and coordinated development of technical education, AICTE is the correct answer.

Option A:
The University Grants Commission oversees universities in general and focuses on broader higher education, not specifically on technical programmes. While it coordinates university education, it does not directly regulate engineering and management institutions the way AICTE does. Thus, Option A is not the best fit here.

Option B:
The All India Council for Technical Education develops norms, accreditation guidelines and approval processes tailored to the needs of technical disciplines. Its specialised focus on engineering, pharmacy, architecture and management closely matches the description in the stem. This confirms its correctness as the answer.

Option C:
The National Medical Commission regulates medical education and the medical profession, dealing with MBBS and related health courses. It has a very different sectoral focus from technical and management education. Therefore, Option C does not match the role described.

Option D:
The National Assessment and Accreditation Council is an accreditation body that evaluates all types of higher education institutions for quality. It does not act as the main regulator for technical education planning and approvals, so Option D is not appropriate.

UGC, AICTE and NCTE are statutory bodies empowered by Acts of Parliament to regulate segments of higher education. They issue regulations, grant approvals and ensure institutions meet minimum standards. Their core function is to control and guide quality and expansion. Thus, they are best described as regulatory agencies.

Option A:
Regulatory agencies have authority to frame rules, recognise institutions and take action when norms are violated. UGC, AICTE and NCTE perform precisely these roles in their respective domains. This is why “regulatory” is the correct term.

Option B:
Examination agencies mainly conduct tests and evaluate candidates, roles more typical of bodies like the National Testing Agency. While regulators may influence examinations indirectly, they are not primarily examination agencies, so this option is wrong.

Option C:
Placement agencies help students secure jobs and internships and do not possess statutory powers over institutions. Therefore, this option does not fit the description.

Option D:
Media agencies create and distribute content to the public and have no regulatory authority in higher education governance. Hence, this option is not appropriate.

Spiral of silence theory suggests that people monitor the climate of opinion and are less likely to express views they perceive as unpopular for fear of social isolation. Over time,majority opinions appear even stronger as minority voices remain silent. The stem describes exactly this reluctance to express minority opinions. Therefore,it refers to the spiral of silence theory.

Option A:
Two step flow focuses on opinion leaders transmitting media messages,not on fear of isolation.

Option B:
Agenda setting addresses issue salience,rather than willingness to speak.

Option C:
Gatekeeping concerns selection of information by media professionals,not individuals' self censorship.

Option D:
Spiral of silence explains why certain perspectives may disappear from public discussion even if many privately hold them,making option D correct.

Upamana is the pramana by which one comes to know something by recognising its similarity to a described, already known object. For example, after hearing that a gavaya is like a wild cow, one later identifies the gavaya by comparing it with cows one has seen. This process centrally involves grasping resemblance rather than direct perception or inference from a sign. Hence the comparative knowledge mentioned in the stem is called upamana.

Option A:
Option A, sabda, is testimony received from a reliable speaker or scripture. Although a description initiates the process of upamana, the decisive cognition of the new object occurs through comparison, not mere acceptance of words.

Option B:
Option B, smriti, is memory, which recalls past experiences but does not by itself introduce a new, previously unknown object through comparison. It is therefore not the pramana described.

Option C:
Option C, pratyaksha, is direct perception produced by sense-object contact. In the example of recognising a gavaya, the senses do perceive the animal, but the crucial knowledge that “this is that described animal” arises through comparison, which is upamana.

Option D:
Option D is correct because upamana highlights similarity as the operative factor in this new cognition. Indian logicians treat it as a distinct and important source of knowledge about unfamiliar entities.

An Institutional Development Plan is envisaged as a comprehensive school level plan that sets out academic, infrastructural and administrative priorities based on data and contributions from teachers, leaders and the community.

Option A:
Option A is incorrect because limiting the plan to canteen menus trivialises its role and ignores its academic and developmental focus.

Option B:
Option B is correct as it describes a broad, data informed improvement plan developed with participation from school staff and local stakeholders.

Option C:
Option C is wrong since NEP promotes transparency and collaboration; the IDP is not meant to be a secret document prepared only for inspectors.

Option D:
Option D is incorrect because the IDP covers far more than cultural events; annual day functions, if mentioned at all, are only a small part of overall school planning.

Each octal digit is converted to a 3-bit binary group. For octal 27₈, the digit 2 becomes 010₂ and the digit 7 becomes 111₂. Combining these groups gives 010111₂. This pattern represents the correct binary equivalent of 27₈.

Option A:
Option A, 001111₂, corresponds to octal 17₈ and not 27₈. Its first group 001₂ represents 1 rather than 2.

Option B:
Option B, 011111₂, would map to octal 37₈, since 011₂ equals 3 and 111₂ equals 7. This is different from the given octal number.

Option C:
Option C, 011011₂, converts back to octal 33₈, as both groups 011₂ equal 3. It clearly does not match 27₈.

Option D:
Option D is correct because 2 maps to 010₂ and 7 maps to 111₂. Concatenating those groups produces the binary representation 010111₂ for 27₈.
