UGC NET Questions (Paper – 1)

Interpersonal communication is the exchange of information,ideas and emotions between two or a few persons in direct contact. In face to face interaction,people can use verbal as well as non verbal cues to co create meaning. The stem clearly refers to two persons sharing ideas and feelings,which matches the standard definition of interpersonal communication.

Option A:
Interpersonal communication involves mutual sharing and response between individuals in close psychological and often physical proximity. Because the situation describes two people interacting face to face,this option accurately captures the level and type of communication involved.

Option B:
Intrapersonal communication occurs within a single individual,such as self talk or internal reflection,so it cannot describe interaction between two persons.

Option C:
Mass communication refers to one to many messages transmitted through media like TV or radio to large,heterogeneous audiences,not a dyadic conversation.

Option D:
Group communication involves several people interacting together rather than just two in a dyad,so it does not precisely fit the stem.

NEP 2020 highlights the importance of strong academic and administrative leadership in schools. It recommends structured programmes to prepare principals in instructional leadership, human resource management and community engagement. Ongoing support ensures they remain effective change agents.

Option A:
This option captures NEP’s call for professionalising school leadership roles.

Option B:
Relying purely on trial and error can lead to inconsistent performance and is not adequate.

Option C:
Political selection undermines merit-based leadership and is criticised.

Option D:
Principals are expected to guide teaching and learning, not just do paperwork.

Statements A, B and D are correct and together summarise the relationship between carrying capacity, environmental limits and sustainable development. Carrying capacity describes the maximum sustainable load on an environment, and exceeding it can cause depletion and degradation. Sustainable development tries to align human activities with these ecological limits. Statement C is incorrect because technological innovations can increase or sometimes decrease effective carrying capacity by changing resource use efficiency and environmental impact. Hence, the correct combination is A, B and D only.

Option A:
Option A is incorrect because it lists only A and B, leaving out D. Although A and B accurately define carrying capacity and consequences of overshooting it, D is also correct in linking sustainability goals to staying within ecological limits. Excluding D makes the set incomplete.

Option B:
Option B is incorrect because it combines B, C and D and treats C as correct. C is wrong because technology can alter carrying capacity, for example through improved agricultural productivity or more efficient energy use. Including a false statement makes this combination unacceptable.

Option C:
Option C is incorrect because it asserts that all four statements A, B, C and D are correct. While A, B and D are correct, C contradicts the dynamic understanding of carrying capacity influenced by technological and social changes. The presence of an incorrect statement invalidates the entire set.

Option D:
Option D is correct because it identifies the three statements that align with ecological and sustainability concepts and excludes the one that is clearly false. It recognises both the definitional and policy dimensions of carrying capacity and reflects the essence of the development–environment relationship in the unit.

A confidence interval provides a range of plausible values for a population parameter based on sample data and a chosen confidence level, such as 95 percent. It accounts for sampling variability and offers more information than a single point estimate. Interpreting the interval helps researchers understand the precision of their estimates and the uncertainty surrounding them. Therefore, the interval described in the stem is correctly called a confidence interval.

Option A:
Confidence intervals are built using the sampling distribution of the statistic and reflect both sample size and variability. A narrower interval indicates more precise estimation, whereas a wider one signals greater uncertainty. These properties align directly with the description of an interval likely to contain the true parameter.

Option B:
A p-value indicates the probability of obtaining results as extreme as those observed, assuming the null hypothesis is true, and is used for hypothesis testing rather than interval estimation. It is not itself an interval around a statistic. Hence, p-value is not the correct completion.

Option C:
Effect size quantifies the magnitude of a relationship or difference but does not by itself convey the sampling uncertainty around the estimate. It can be accompanied by a confidence interval, but it is conceptually distinct. Therefore, effect size is not appropriate here.

Option D:
A test statistic is a single calculated value, such as a t or F value, used to decide whether to reject the null hypothesis, not an interval within which a parameter is likely to lie. Thus, test statistic is not the term being defined in the stem.

Such statements specify observable abilities learners should demonstrate after instruction—these are learning outcomes guiding teaching and assessment.

Option A:
Time tables schedule classes; they do not describe expected learner performance.

Option B:
Outcomes specify what students will be able to do (observable achievement), matching the stem.

Option C:
Budgets concern finance, not learning achievements.

Option D:
Holidays are calendar breaks, unrelated to learning performance statements.

NEP 2020 considers libraries central to promoting reading culture and inquiry. It suggests modernising them, ensuring access to good books and digital resources, and integrating library time into timetables. Libraries serve all grades and support project-based learning.

Option A:
This option matches the policy’s strong emphasis on libraries as learning hubs.

Option B:
Treating them as optional ignores their role in literacy and critical thinking.

Option C:
Using them as storage wastes valuable space and opportunity.

Option D:
Reserving them only for meetings undermines student access.

The tragedy of the commons refers to situations where no one owns a resource and each user has an incentive to take as much as possible. When everyone behaves this way, total extraction exceeds sustainable limits and the resource is degraded or destroyed. The problem lies in unregulated open access, not in sharing itself. Hence, the option describing overuse by self-interested individuals leading to degradation is correct.

Option A:
Option A is incorrect because nature alone cannot guarantee conservation when human extraction is unregulated. Without rules, open-access resources are vulnerable to overuse.

Option B:
Option B is correct as it captures the core mechanism: individual self-interest in open-access situations can produce collectively harmful outcomes. It summarises Hardin’s argument about grazing on common pastures.

Option C:
Option C is incorrect since communities with shared rules can often manage resources sustainably. Many studies show successful common property regimes that avoid tragedy through collective action.

Option D:
Option D is incorrect because private ownership does not always lead to depletion. Owners may have strong incentives to manage resources prudently over time.

When universities undertake outreach programmes to address local needs in education, health and environment, they are exercising their social responsibility. These actions show concern for societal well-being and development beyond campus boundaries, so “social” is the correct term.

Option A:
Option A is correct because social responsibility emphasises the obligation of institutions to use their knowledge and resources for the public good, which is exactly what such community-oriented activities represent.

Option B:
Option B is incorrect since “purely commercial” responsibility would focus on profit-making transactions rather than service and community welfare.

Option C:
Option C is wrong because “military” responsibility relates to defence activities, which are not what literacy drives or health camps are about.

Option D:
Option D is incorrect as “electoral” responsibility would involve managing or influencing elections, not running educational or health campaigns for nearby communities.

To represent integers from 0 to 1023, we need 1024 distinct codes. A binary pattern of n bits can represent 2^n distinct values. The smallest power of two greater than or equal to 1024 is 2^10. Therefore, 10 bits are required to cover the entire range from 0 to 1023.

Option A:
Option A uses 8 bits, which give 2^8 = 256 patterns. These patterns represent only the range 0 to 255. Since 1023 is much larger than 255, 8 bits are insufficient for this range.

Option B:
Option B uses 9 bits, which give 2^9 = 512 patterns. This allows representation only from 0 to 511. Because 1023 is greater than 511, 9 bits still do not cover the full required range.

Option C:
Option C uses 10 bits, which give 2^10 = 1024 patterns. These patterns can represent all integers from 0 to 1023 without any gap. Hence 10 bits are exactly sufficient and not excessive.

Option D:
Option D uses 11 bits, which give 2^11 = 2048 patterns. This covers a much larger range than necessary for 0 to 1023. It is technically sufficient but not the minimum, so it is not the best answer.

Statements A, B and C are correct, whereas D is incorrect. A is true because face-to-face interaction includes verbal content, voice tone and body language, and allows rapid feedback. B is true since written notices typically provide only text and do not convey vocal or facial cues, making them lean. C is true as rich channels help clarify complex or ambiguous issues by permitting questions and elaboration. D is false because emotional issues are often better handled through richer channels that allow empathy and nuance, not lean channels alone.

Option A:
Option A is incorrect because it lists A and B only and omits C, which highlights the particular usefulness of rich channels for complex messages. Without C, the description of richness is partial. Therefore A and B only cannot be the correct answer.

Option B:
Option B is incorrect because it groups B and C only and leaves out A, ignoring the classic example of face-to-face communication as a rich channel. Since A is also correct, B and C only is incomplete.

Option C:
Option C is correct because it brings together A, B and C, presenting a coherent view of rich versus lean channels and their appropriate use. It excludes D, which overstates the value of lean channels for emotional content. As it includes all and only the correct statements, this option is the right one.

Option D:
Option D is incorrect because it treats all four statements as correct, including D. D conflicts with communication practice by claiming that lean channels are always superior for emotional matters. Mixing this false claim with accurate statements makes the option invalid.

The National Disaster Management Authority is the apex body for disaster management in India. Under the Disaster Management Act, the Prime Minister serves as its chairperson, signalling high-level political commitment to disaster risk reduction. This arrangement facilitates coordination among ministries and between the central and state governments. Therefore, identifying the Prime Minister as the head of NDMA is correct.

Option A:
Option A is correct because it matches the statutory design that places disaster management under the direct leadership of the head of government. This ensures that major disaster responses and policies receive attention at the highest executive level.

Option B:
Option B is incorrect since the Finance Minister, while crucial for allocating funds, does not chair the NDMA. Financial decisions support disaster programmes but do not confer leadership of the authority.

Option C:
Option C is incorrect; the Chief Justice of India leads the judiciary and does not head executive agencies. Courts may review disaster-related actions, but they are institutionally separate from NDMA.

Option D:
Option D is incorrect because the Chief Election Commissioner oversees electoral processes. Election management and disaster management are distinct domains with separate legal frameworks and authorities.

Statements A, C and D correctly describe teaching support systems and how they contribute to learning. A is true because libraries, laboratories and ICT tools provide structured resources that support instruction. C is true since these systems are most effective when thoughtfully planned into teaching–learning activities. D is true as resources like labs and simulations create concrete, experiential learning opportunities. B is wrong because support systems are designed for use by both teachers and learners, and E is wrong because mere availability does not guarantee appropriate or effective use. Hence the wrong statements are B and E only, making B and E only the correct combination.

Option A:
Option A singles out B as the only wrong statement and ignores E, which is also wrong. Hence B only cannot be accepted.

Option B:
Option B identifies only E as wrong and overlooks B. Hence E only cannot be accepted.

Option C:
Option C includes A (true) among wrong statements, so A, B and E only is invalid.

Option D:
Option D correctly groups B and E as wrong and leaves A, C and D as correct. Thus B and E only is the correct answer.

Option E includes D (true) among wrong statements, so B, D and E only cannot be chosen.

Statements A, C and D correctly explain the nature and advantages of OER, while statement B is false. OER are freely accessible resources with permissions for reuse and adaptation, they are often shared under licences like Creative Commons and they help reduce costs and expand access. They are not confined to printed textbooks and may include digital media of various kinds. Therefore, the combination containing A, C and D only is the correct answer.

Option A:
Option A is correct because it selects exactly the three true statements and excludes the incorrect restriction in B. It recognises the licensing flexibility and access benefits of OER beyond print formats. This option is fully consistent with ICT-enabled open education practices.

Option B:
Option B is incorrect because it chooses A and C only and omits D. Although A and C are true, D also accurately captures cost and access advantages of OER. Excluding D makes the set of statements incomplete.

Option C:
Option C is incorrect because it groups C and D only and leaves out A. While C and D are correct, statement A provides the core definition of OER regarding free availability and permissions. Without A, the explanation of OER is incomplete.

Option D:
Option D is incorrect because it treats all four statements as correct and thus accepts B. Statement B wrongly limits OER to printed textbooks when they actually include many digital formats, so this combination cannot be accepted.

Statements A, B and D accurately reflect the scope and evolution of cyber law under the IT Act, while C is clearly false. The Act grants legal status to e-records and digital signatures, covers several cyber offences and is periodically updated. Organisational security policies remain essential even with cyber law in place, so legal provisions do not replace internal information security practices. Thus, the correct combination consists of A, B and D only.

Option A:
Option A is incomplete because it includes only A and B and omits D. While recognition of e-records and coverage of cyber offences are true, excluding the possibility of amendments ignores the dynamic nature of cyber law. Therefore, this option fails to list all the correct statements.

Option B:
Option B is incomplete because it lists B and D only and leaves out A. Without acknowledging that the IT Act gives legal recognition to electronic records, the legal foundation of cyber law is not fully captured. Hence, this combination does not represent the complete set of true statements.

Option C:
Option C is correct because it gathers the three true statements and explicitly excludes C, which wrongly suggests that cyber law can replace organisational security measures. It presents a balanced view where law and institutional policies complement each other in managing cyber risks.

Option D:
Option D is incorrect because it assumes that all four statements are correct and thereby accepts C. Since C dismisses the continuing need for security policies, this combination conflicts with the layered approach to information security.

Statements A, B, C and D correctly distinguish internal and external validity and the roles of random assignment and random sampling. Internal validity is about attributing effects to the treatment rather than confounds, while external validity is about generalising beyond the study context. Random assignment strengthens internal validity by equalising extraneous variables across groups, and random sampling supports external validity by making the sample more representative. Statement E is false because a study can have strong internal validity yet limited generalisability, so high internal validity does not guarantee high external validity.

Option A:
Option A is incomplete because it omits D, which correctly highlights the relation between random sampling and external validity. Without D, the link between sampling and generalisability is not fully represented.

Option B:
Option B leaves out statement A, overlooking the fundamental definition of internal validity as ruling out alternative explanations. Even though B and D address external validity and sampling, omitting A weakens the conceptual pair.

Option C:
Option C is correct because it includes all four accurate statements about internal and external validity and their methodological supports. It deliberately excludes E, which wrongly assumes that internal and external validity always go together. Thus this combination precisely reflects textbook distinctions.

Option D:
Option D is incorrect because it includes E, which overstates the relationship between internal and external validity, and it omits B, which defines external validity itself. This mixture of omission and error makes the option unacceptable.

Option E is also wrong because it incorporates E, the false automatic link between internal and external validity. A correct option must not contain this overgeneralisation.
