UGC NET Questions (Paper – 1)

Statements A, B, C, D and E accurately describe sampling techniques, whereas F is false. Statement A is true because probability sampling ensures each element has a known non-zero chance of selection. Statement B correctly defines stratified random sampling, and statement C is right in classifying purposive sampling as non-probability. Statement D is correct since snowball sampling is used to access hidden populations, and E is true as probability methods reduce researcher selection bias, while F is false because convenience sampling does not guarantee representativeness.

Option A:
Option A includes all the correct statements and excludes the incorrect one. By presenting A, B, C, D and E together, it reflects standard textbook definitions of sampling techniques and their implications. Since it leaves out F, which wrongly promises guaranteed representativeness, this option is the correct answer.

Option B:
Option B omits statement E, thereby ignoring the important point that probability sampling minimises researcher bias. Although A, B, C and D are true, excluding E makes the combination incomplete. A correct option must list all relevant true statements for the concept.

Option C:
Option C brings F into the combination along with the correct statements. Because F falsely claims that convenience sampling ensures full representativeness, including it contaminates the set of statements. Any option that mixes false and true statements cannot be accepted as correct.

Option D:
Option D also contains F and even omits A, which is central to the definition of probability sampling. Leaving out a key true statement and adding a false one makes this combination doubly problematic. Consequently this option is invalid.

Statements A, B, C and E describe realistic uses of ICT for enhancing student support, whereas D and F are overly rigid. While online channels can reduce pressure on in-person desks, completely eliminating physical support may not suit all contexts. Feedback mechanisms are also valuable for improving services, so banning them makes little sense. Therefore, the combination A, B, C and E only is correct.

Option A:
Option A is incomplete because it leaves out E, which highlights the role of integrated knowledge bases in delivering consistent answers. Without E, the systemic improvement aspect of ICT-based support is underplayed.

Option B:
Option B is incomplete because it omits A, so it fails to mention basic portal functions such as access to grades and attendance, which are central to many student systems.

Option C:
Option C is incomplete because it excludes A and includes only B, C and E. Although those statements are true, not mentioning portal access to academic and financial records leaves the description of support somewhat narrow.

Option D:
Option D is correct because it groups together portals, chatbots, reminders and knowledge bases as complementary components. By excluding D’s extreme claim about abandoning physical desks and F’s rejection of feedback, it aligns with flexible, student-centred support models.

A necessary condition must be present whenever the outcome occurs. If having a valid admit card is necessary for entry, then anyone who is inside the hall must have such a card. In conditional form this becomes “If a person enters the hall, then the person has a valid admit card.” The statement does not claim that possessing a card alone is enough for entry, only that entry cannot happen without it.

Option A:
Option A treats possessing the card as sufficient for entry, which goes beyond necessity and may ignore other requirements like identity proof.

Option B:
Option B captures the idea that entry implies the presence of the necessary condition, aligning with the logical form “Outcome → Condition.”

Option C:
Option C reverses the direction in a way that ties receiving the card to entering, which is not what the original statement asserts.

Option D:
Option D explicitly mislabels the condition as sufficient but not necessary, contradicting the claim that it is necessary.

NRF is designed as a funding and facilitation body to strengthen research in universities and colleges. It will support projects in sciences, social sciences, arts and humanities. The goal is to build a robust research culture throughout the higher education system, not just in elite institutions.

Option A:
Regulating school exams is not part of NRF’s mandate; that lies with assessment bodies and boards.

Option B:
This option reflects NEP’s intent to make research more inclusive and adequately funded across the system.

Option C:
Sports tournaments, while important, are not the focus of a research foundation.

Option D:
Accreditation is managed through NAC and related bodies, not NRF.

Research is understood as an organized process guided by clearly defined objectives and questions. It relies on systematic procedures for collecting, analyzing and interpreting data to address a problem or gap in knowledge. Objectivity and careful control of bias are emphasized to make the findings credible.

Option A:
Option A is correct because it includes the key features: planning, objectivity, systematic method and knowledge orientation. It covers both discovery of new knowledge and validation of existing knowledge through evidence.

Option B:
Option B presents research as casual and opinion based, which contradicts the disciplined nature of scientific inquiry.

Option C:
Option C reduces research to a single guess, ignoring the need for sustained investigation, data collection and analysis.

Option D:
Option D focuses only on data collection and neglects interpretation and reasoning, without which raw data cannot contribute meaningfully to knowledge.

Option B – learning The terms visual, auditory and kinesthetic are commonly used to describe different ways in which learners prefer to receive and process information. Designing lessons that include diagrams, spoken explanations and hands-on activities caters to these varied learning styles. This multi-sensory approach helps more students engage with the material in ways that feel natural to them. Therefore, accommodating such preferences primarily addresses learners’ learning styles.

Option A:
Option A, socio-economic, refers to learners’ economic and social background, such as family income and parental education. While these factors influence learning opportunities, they are not the same as the preferences for visual, auditory or kinesthetic modes of learning mentioned in the stem. Hence, socio-economic styles are not a recognized concept here.

Option B:
Option B explicitly points to learning styles, which are patterns in how individuals tend to perceive and process information. When teachers include a variety of activities like demonstrations, discussions and experiments, they are trying to match these styles. This option therefore aligns directly with the description in the question.

Option C:
Option C, leadership, relates to how individuals influence and guide others in group settings. Leadership styles describe whether a person is democratic, authoritarian or laissez-faire, which is quite different from how a learner prefers to absorb information. Thus, leadership styles do not fit the context of visual, auditory and kinesthetic preferences.

Option D:
Option D, disciplinary, might refer to approaches to maintaining order and discipline in the classroom. It has little to do with the sensory channels through which students learn best. For that reason, disciplinary styles cannot correctly complete the statement in the question.

Interpersonal communication typically occurs between two individuals who are mutually aware of each other and can exchange feedback in real time. Academic counselling sessions involve direct eye contact, personalized dialogue and immediate responses tailored to the student’s needs.

Option A:
Option A is an example of public or group communication where one person addresses many listeners with limited individual feedback and little personal relationship.

Option B:
Option B is correct because it is a dyadic, face-to-face interaction in which teacher and student exchange messages personally and adjust to each other’s responses.

Option C:
Option C, a notice on the website, is a mediated one-to-many written message with no immediate feedback from individual students, so it is not interpersonal.

Option D:
Option D is a mass-media style broadcast to many colleges; feedback is indirect and delayed, so it is closer to mass communication than interpersonal communication.

The NGT is a specialised judicial body established to handle environmental disputes quickly and with technical expertise. It adjudicates civil cases involving substantial questions relating to the environment, including enforcement of legal rights, compensation and restoration. Its core role is to decide such cases, not to legislate or directly manage resources.

Option A:
Option A is incorrect because making laws is the function of Parliament and state legislatures; the NGT applies existing environmental laws rather than enacting new ones.

Option B:
Option B is correct since the NGT’s mandate is to hear and dispose of environmental cases concerning pollution, forests, biodiversity and other natural resources.

Option C:
Option C is incorrect as day-to-day management of parks and sanctuaries is handled by forest and wildlife departments, not by the NGT.

Option D:
Option D is incorrect because tax collection is carried out by revenue authorities; the NGT may impose penalties or compensation, but it is not a tax-collecting agency.

Applied research is undertaken to address concrete problems in real-life settings, such as improving a particular teaching strategy, developing a new counselling technique or refining an organisational practice. Its outcomes are intended to be directly useful for decision-makers and practitioners. While it may rely on theories and findings from basic research, the central motivation is to produce actionable solutions. Therefore, research that aims primarily at solving an immediate practical problem is correctly termed applied research.

Option A:
Basic research aims to extend theoretical knowledge without necessarily focusing on an immediate practical issue, even though its results may later influence practice. It asks “why” questions at a fundamental level more than “how to fix this problem now.” Because the stem emphasises practical solutions in a specific context, basic research does not fit as the best answer.

Option B:
Applied research directly targets specific problems and is often commissioned by organisations or agencies that need guidance for action. For example, a college might sponsor a study to identify reasons for student dropout and recommend interventions. Such problem-focused orientation aligns exactly with the stem, so applied research is the appropriate completion.

Option C:
Fundamental research is another term commonly used for basic research that pursues knowledge for its own sake rather than to solve immediate practical issues. In this question, however, the emphasis lies on finding solutions for a particular problem, so fundamental research is not the correct choice.

Option D:
Historical research investigates past events, documents and trends to interpret how and why they occurred. Although historical insights can inform present decisions, the method is not specifically about solving a current practical problem in a defined context. Hence, historical research does not match the scenario described.

This option is correct because a leap year adds one extra day to February, making it 29 days instead of 28. As a result, the total number of days in the year becomes 366. This adjustment keeps the calendar year synchronised with the astronomical year. Therefore, a leap year has 366 days.

Option A:
366 days equal 365 regular days plus 1 extra day. This extra day compensates for the fact that the Earth's orbit around the Sun is slightly more than 365 days. Thus, this option accurately describes the length of a leap year.

Option B:
365 days correspond to a common, non-leap year. Although this is the usual number of days in a year, it does not apply when February has 29 days. Hence, this option is not correct for a leap year.

Option C:
364 days would give a year composed of exactly 52 weeks, but standard calendars do not use this length. It neither matches common nor leap years. Therefore, this option is wrong.

Option D:
360 days is sometimes used in financial calculations as a simplification, but it is not the actual number of days in either a common or leap year. Thus, it does not answer the question correctly.

Communication is commonly analysed in terms of certain basic elements. There is a sender who initiates the message, the message itself, a channel or medium, a receiver and feedback indicating how the message was understood. In classroom communication, the teacher and students alternately act as sender and receiver. The presence of feedback allows for clarification and adjustment.

Option A:
This option correctly states the standard components of communication models. It is applicable to both general and classroom contexts and helps teachers design clearer messages and interpret student responses more effectively.

Option B:
This option lists some physical items used in teaching but does not capture the abstract components of the communication process. Chalk, duster and podium are aids or facilities rather than essential elements of communication.

Option C:
This option mentions administrative tools and facilities that support academic management. They are not part of the communication model as such and therefore do not answer the question.

Option D:
This option refers to infrastructure, which provides the physical environment for communication. While important, they are not the conceptual elements of the communication process itself.

A nibble is defined as a group of four bits. It represents half of a standard 8-bit byte and is often used when working with single hexadecimal digits, since each hex digit maps to exactly four binary bits. Thus, a nibble consists of 4 bits.

Option A:
Option A, 8 bits, defines a byte rather than a nibble. A nibble is intentionally half the size of a byte.

Option B:
Option B, 2 bits, would be called a dibit or pair, not a nibble. It does not capture the structure commonly used with hexadecimal digits.

Option C:
Option C is correct because the term nibble arose specifically to describe a 4-bit quantity. This grouping is natural given the close link between 4 bits and one hex digit.

Option D:
Option D, 16 bits, describes a word or half-word in some architectures but is far larger than a nibble.

Statements A and B correctly describe core dimensions of institutional autonomy. Academic autonomy focuses on curricular design, pedagogy and assessment choices within broad regulatory norms, while administrative autonomy covers internal management and staffing decisions. Statement C is wrong because financial autonomy does not remove accountability; institutions using public funds are still subject to audits and regulations. Statement D is also wrong because even autonomous institutions remain subject to external quality assurance and accreditation processes. As a result, the correct combination is A and B only.

Option A:
Option A is incorrect because it recognises only A as correct and excludes B. Administrative autonomy is also a recognised dimension of institutional autonomy in governance, so leaving it out makes this combination incomplete.

Option B:
Option B is incorrect because it treats only B as correct and ignores A, which accurately reflects the nature of academic autonomy. Institutions generally require both academic and administrative autonomy for effective self-governance, so this option is too narrow.

Option C:
Option C is incorrect because it includes C, which mischaracterises financial autonomy as absence of accountability. Even when institutions have more flexibility in generating and using resources, they remain accountable for transparency and compliance with public norms, so combining A with C is inconsistent.

Option D:
Option D is correct because it combines statements A and B, both of which capture essential and accurate aspects of institutional autonomy. At the same time, it excludes C and D, which wrongly suggest that autonomy eliminates financial accountability and external quality checks.

Inductive arguments aim to make their conclusions probable rather than certain. An inductive argument is considered strong when the truth of its premises would make the conclusion very unlikely to be false. This probabilistic standard fits the principle stated in the stem. Hence the description mainly applies to inductive arguments.

Option A:
Option A, symbolic, simply refers to a way of representing arguments using symbols and can apply to many forms. It does not specify a particular probabilistic standard of strength. Therefore symbolic is not the correct answer.

Option B:
Option B, deductive, is evaluated by validity, where it is impossible for true premises to yield a false conclusion. Deduction does not usually talk of degrees of probability or strength. Thus deductive arguments are assessed differently from what the stem describes.

Option C:
Option C, fallacious, denotes arguments containing errors in reasoning. A fallacious argument is weak or invalid by definition and does not satisfy the stated condition. Hence fallacious cannot be correct here.

Option D:
Option D correctly identifies inductive arguments as those judged by how unlikely it is for the premises to be true while the conclusion is false. Strong induction therefore fits the standard mentioned in the question.

Contraries are propositions that cannot both be true at the same time but can both be false. On the square of opposition, the universal affirmative 'All S are P' and the universal negative 'No S are P' have this relation. There are circumstances where neither statement holds, making both false. Thus the relationship described in the stem is that of contraries.

Option A:
Option A, contradictories, are pairs of propositions that cannot both be true and cannot both be false; exactly one must be true. This relation holds between A and O or E and I, not between A and E. Therefore contradictories is not correct here.

Option B:
Option B, subcontraries, are propositions that cannot both be false but can both be true, a relation found between I and O propositions. Universal statements do not stand in this relation, so subcontraries cannot be the right answer.

Option C:
Option C, subalterns, refers to pairs where the truth of a universal implies the truth of its corresponding particular, such as A implying I. This is a different relation from the one asked about in the question.

Option D:
Option D is correct because contraries specifically describe the relation between universal affirmative and universal negative propositions on the square of opposition, matching the description in the stem.
