UGC NET Questions (Paper – 1)

Statements A, B, D and E are correct, whereas C and F are false. Simple statements have no smaller statement parts, and compound statements are built from them with connectives. Negation does flip truth values in classical logic, and each atomic statement gets its own column in a truth table. C is wrong because connectives also determine how component truth values combine, and F is wrong because UGC NET questions frequently use compound statements.

Option A:
Option A is incorrect because it leaves out statement E, which accurately describes how truth tables are constructed. While A, B and D are true, omitting E means the answer does not include all correct statements. The description of truth-table practice is therefore incomplete in this option.

Option B:
Option B is correct since it brings together A, B, D and E, the four statements that match standard propositional logic. It excludes C, which ignores the role of connectives, and F, which falsely denies the presence of compound statements in exam questions. This combination therefore reflects both theory and examination practice.

Option C:
Option C is wrong because it includes C along with otherwise correct statements. C claims that connectives do not matter for truth values, which contradicts the whole idea of truth-functional operators. Adding a false statement makes the entire combination unacceptable.

Option D:
Option D is incorrect because it omits A, the basic definition of a simple statement, and it starts from B. Although B, D and E are true, without A the picture of the distinction between simple and compound statements is incomplete. Thus this option fails to represent the full set of correct statements.

Achieving objectives reflects effectiveness; optimal use of time/resources reflects efficiency. The stem includes both, so it indicates high effectiveness and efficiency.

Option A:
Effectiveness and efficiency together mean goals are met and resources/time are used optimally, exactly as described.

Option B:
Authoritarianism is about control/obedience, not outcomes + resource optimisation.

Option C:
Conformity is adherence to norms, not necessarily improved outcomes or resource use.

Option D:
Rigidity is inflexibility and can reduce effectiveness/efficiency when learners need adaptation.

A research problem is the clearly defined issue or difficulty that the researcher intends to investigate through systematic inquiry. It pinpoints what exactly is unsatisfactory or unknown in the existing knowledge or practice. This statement guides the formulation of objectives, hypotheses and methods. Therefore, the clear and precise statement that identifies the central issue of the study is correctly called the research problem.

Option A:
A research objective states what the researcher plans to accomplish in concrete or measurable terms, but it is derived from the prior identification of the research problem. Objectives break down the problem into specific tasks rather than defining the core issue itself. Hence, research objective does not represent the fundamental statement of the central issue.

Option B:
The research problem represents the starting point of any scientific investigation by converting a felt difficulty or gap into a form that can be studied empirically. It provides focus and direction, helping to avoid a diffuse or aimless inquiry. Because it is this statement that identifies the central issue of investigation, research problem appropriately completes the stem.

Option C:
A research hypothesis is a tentative, testable prediction about the relationship between variables that emerges from the research problem and theory. It does not itself describe the broader contextual issue that motivates the study. Thus, research hypothesis is not the best term for the clear statement of the central issue.

Option D:
A research design is the overall plan specifying how data will be collected and analysed, but it presupposes that the problem has already been stated. It focuses on procedure rather than on articulating the core problem. Therefore, research design is not the correct completion for the stem.

The message is the core content that the sender wants the receiver to understand. It consists of concepts,explanations,examples and instructions structured into meaningful units. When a teacher speaks or writes for students,the ideas and information being conveyed constitute the message. Thus message is the correct term for what is transmitted.

Option A:
In communication theory,the message is distinct from both the person who sends it and the medium that carries it. It is the "what" of communication that learners must decode. The description in the stem aligns perfectly with this definition,making this option appropriate.

Option B:
Channel refers to the physical or technological medium such as air,whiteboard or internet that carries the message from teacher to student. It is not the content itself,so this option does not fit the blank.

Option C:
Noise is any unwanted interference that distorts the message while it is being transmitted,such as outside sounds or technical glitches. It is the opposite of the intended ideas and cannot be equated with them.

Option D:
Context denotes the environment,relationships and prior experiences that surround the communication event. While context influences interpretation,it is not the same as the ideas and information transmitted.

Westley and MacLean's model highlights that communication becomes interactive when receivers send feedback to the original source. This feedback allows adjustment and continuous exchange. The stem refers to feedback converting communication into a more dynamic process,which is best described as interactive.

Option A:
One way communication lacks feedback and therefore remains linear.

Option B:
Interactive communication recognises that receivers actively respond,making this option correct.

Option C:
Mechanical refers to technical aspects rather than relational exchange.

Option D:
Ritualistic emphasises symbolic ceremonies,not feedback loops.

The decimal system uses ten symbols, namely 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. Because a positional system's base equals the number of distinct digit symbols, the base of decimal is 10. Therefore, the number of distinct digit symbols in decimal is 10.

Option A:
Option A, 9, would omit one symbol and cannot represent all decimal digits. Since we clearly use ten distinct symbols, this count is too small.

Option B:
Option B is correct because counting from 0 to 9 gives ten unique digits used in everyday arithmetic. This property defines decimal as a base-10 system.

Option C:
Option C, 8, would correspond to an octal system, not to decimal. Octal digits range from 0 to 7 only.

Option D:
Option D, 16, describes the hexadecimal system, which uses digits 0–9 and letters A–F, not the decimal system.

The pattern here is given by aₙ = 3n⁴ − n² + 4 with n starting from 1. Substituting n = 1, 2, 3, 4 and 5 yields 6, 48, 238, 756 and 1854, which are exactly the numbers in the series. Applying the same expression for n = 6 gives 3856. Hence 3856 is the only value that keeps this quartic-based pattern consistent.

Option A:
Option A, 3824, is 32 less than the value obtained from aₙ = 3n⁴ − n² + 4 when n = 6. To accept 3824 we would need to subtract 32 only at the last term, which is not indicated by the earlier entries. As a result, this option does not preserve the polynomial rule and is incorrect.

Option B:
Option B, 3840, is still smaller than the required value and does not equal the output of the formula at n = 6. It represents a partial correction toward the right term but still breaks the functional relationship. Therefore option B cannot correctly continue the series.

Option C:
Option C, 3856, matches exactly the value predicted by 3n⁴ − n² + 4 for n = 6. It respects the same combination of a fourth-power term and a negative square adjustment that shapes the growth of the sequence. Because the same rule explains all the given terms and leads naturally to 3856, this option is correct.

Option D:
Option D, 3872, is 16 greater than the polynomial value and cannot be generated by the rule for the sixth position. Introducing this extra amount would break the algebraic pattern that the series follows. Thus option D is not a valid continuation.

Statements A, B, C and D correctly relate “if”, “only if” and necessary conditions to their symbolic forms, and F is also true, while E is false. The biconditional is true exactly when p and q share the same truth value, not when they differ. Treating “only if” carefully is crucial for distinguishing what is necessary from what is sufficient. Hence the correct set of statements is A, B, C, D and F only.

Option A:
Option A is incomplete because it omits D and F, leaving out both the explicit link to necessary conditions and the exam relevance of misreading “only if”. Although A, B, C and E mention some relationships, they include E, which wrongly states the truth pattern of the biconditional. This makes the option incorrect.

Option B:
Option B is wrong because it includes E, which claims that “p if and only if q” is true when p and q differ in truth value. That is the truth condition for exclusive disjunction, not for the biconditional. Including E makes the combination logically inconsistent.

Option C:
Option C is correct as it gathers A, B, C and D, which correctly express equivalences and necessary condition symbolism, and F, which notes the importance of reading these connectives properly in exams. It excludes E, avoiding the confusion between biconditional and exclusive or. This matches standard logical teaching.

Option D:
Option D is incorrect since it omits A and replaces it with B, C, D, E and F. Without A, the equivalence of “p only if q” with “If p then q” is not stated, and including E still misrepresents the truth conditions of the biconditional. Therefore it cannot be the right answer.

Statements A, B and D are correct: indigenous knowledge contains sustainable practices, combining it with science can improve management and rights plus prior informed consent are key ethical principles. Statement C is incorrect because indigenous knowledge continues to be relevant for contemporary environmental problems like climate adaptation and biodiversity conservation. Therefore, the combination A, B and D only is correct.

Option A:
Option A is incomplete because it omits D, which rightly stresses the need for respecting rights and consent when using indigenous knowledge. Without D, ethical aspects are not fully represented.

Option B:
Option B is incorrect as it includes C, implying that indigenous knowledge is obsolete, which contradicts numerous examples of its contemporary value.

Option C:
Option C is incorrect since it groups B, C and D and treats C as correct. Although B and D are valid, the inclusion of C makes the combination unacceptable.

Option D:
Option D is correct because it includes all three true statements while excluding the disparaging and incorrect statement C. It reflects both the practical and ethical dimensions of using indigenous knowledge in environmental management.

NEP 2020 frequently refers to SEDGs as groups that face barriers due to social and economic conditions. These include SCs, STs, OBCs, minority communities, girls, differently-abled persons and others. Special schemes and funds are proposed to support them. The acronym explicitly stands for Socio-Economically Disadvantaged Groups.

Option A:
Option A mis-expands the acronym and does not relate to equity concerns.

Option B:
This option matches the text of NEP and clarifies the focus on disadvantaged learners.

Option C:
Option C invents a meaning that refers only to graduates, which is not the usage in the policy.

Option D:
Option D is unrelated to the equity framework described in NEP.

Statements A, C and D correctly capture the teacher’s socialising role. A is true because teachers introduce learners to shared norms and values through curriculum and interaction. C is true as teachers can model and promote respect for diversity, helping learners live in pluralistic societies. D is true since when teachers engage with the community, they help connect school experiences with wider social realities. B is false because effective value education requires dialogue, reflection and critical engagement, not mere reading of text, and E is false because learners observe teachers’ conduct closely and learn values from their behaviour; therefore A, C and D only is correct.

Option A:
Option A includes A, C and D, which together show transmission of values, promotion of cohesion and school–community connection. It excludes B and E, which minimise discussion and role modelling, and thus accurately represents the teacher’s socialising function. Hence this is the correct option.

Option B:
Option B lists A and C but omits D, ignoring the importance of community-related activities in strengthening the social role of the school. Without D, the description of the teacher as socialising agent is incomplete.

Option C:
Option C contains C and D only and leaves out A, which states the fundamental role of teachers in transmitting social values and norms. Because A is a core part of socialisation, this option cannot be considered complete or correct.

Option D:
Option D groups A, B, C and D but includes B, which restricts value education to reading text and ignores discussion and critical thinking. Including a false statement makes the combination logically inconsistent.

Option E combines A, C, D and E but accepts E, which wrongly claims that the teacher’s conduct is unimportant in value education. Since role modelling is central to value transmission, A, C, D and E only cannot be accepted as correct.

The IPCC AR6 Synthesis clearly states that the remaining carbon budget for 1.5°C is very small and shrinking quickly. It emphasises that rapid, deep and sustained emission cuts in the 2020s are essential to keep this temperature goal within reach. Early action reduces the chances of overshoot, lowers long-term costs and avoids locking in high-carbon infrastructure. Therefore, the option that highlights urgent and strong mitigation in this decade captures the heart of the report’s message.

Option A:
This option is correct because it directly reflects the wording used by the IPCC about rapid, deep and sustained cuts. It recognises that mitigation must happen now, not at some distant future date. It also links the scale and speed of emission reductions to the 1.5°C limit, which is central to the report.

Option B:
This option is incorrect because delaying major emission reductions until after 2050 would make 1.5°C practically unattainable. The report warns that postponement increases costs and risks of irreversible impacts. Therefore, it contradicts the urgency stressed in AR6.

Option C:
This option overemphasises lifestyle changes and ignores the need for structural shifts in energy, transport and land use. The report stresses that both demand-side and supply-side transformations are needed. Hence, it is incomplete and not the best answer.

Option D:
This option wrongly suggests that mitigation no longer matters. AR6 repeatedly states that every fraction of a degree of avoided warming reduces impacts and risks. So, claiming mitigation has no effect is directly opposed to the scientific findings.

Statements A, B, D and E accurately describe expectations regarding public disclosure. A is true because basic information on programmes, admissions and fees must be accessible. B is true as sharing decisions or summaries of statutory bodies promotes transparency. D is true since regulators and accreditation agencies often prescribe disclosure requirements. E is true because clear and student-friendly information helps applicants make informed choices. C is false because institutions are not discouraged from disclosure; rather, they are expected to be open, and F is false as outdated or inaccurate websites can damage credibility.

Option A:
Option A is incorrect because it omits E and thus fails to mention the importance of presenting information in a way that students can easily understand and use.

Option B:
Option B is incorrect because it includes only B, D and E and omits A, leaving out the fundamental requirement to provide basic programme and fee information online.

Option C:
Option C is incorrect because it ignores D and includes only A, B and E, not explicitly acknowledging that disclosure is often mandated by regulatory and accreditation norms.

Option D:
Option D is correct because it brings together A, B, D and E, the true statements that emphasise accessible information, transparency, regulatory norms and student-centred presentation, while excluding C and F, which wrongly discourage disclosure and dismiss the importance of website accuracy.

NEP 2020 uses the term SEDGs for groups facing social and economic barriers, such as SCs, STs, OBCs, minorities, girls, children in rural or remote areas and transgender persons. Economically privileged learners in elite urban schools are comparatively advantaged and hence least likely to be considered SEDGs.

Option A:
Scheduled Castes and Scheduled Tribes are explicitly recognised as socio-economically disadvantaged groups needing targeted support and therefore clearly fall within SEDGs.

Option B:
Children from rural and remote regions often face difficulties of access, infrastructure and quality, so they are typically included in SEDGs, not excluded.

Option C:
Economically well-off students in elite urban schools enjoy better resources and opportunities, so they are least likely to be categorised as SEDGs in NEP 2020.

Option D:
Transgender persons are specifically mentioned as needing special measures for inclusion and safety and therefore are part of the SEDG focus, not outside it.

Paralanguage includes vocal features such as pitch,volume and speed that accompany spoken words. Changing pitch and slowing speech draw attention to a key message without altering the words themselves. This is a classic use of paralanguage for emphasis.

Option A:
Semantics deals with meanings of words,not the way they are voiced.

Option B:
Proxemics involves physical distance between people,not voice quality.

Option C:
Therefore paralanguage accurately names the vocal behaviour described.

Option D:
Haptics concerns communication through touch,which is not referred to in the stem.
