UGC NET Questions (Paper – 1)

This option is correct because when two ratios are equal, we say they are in proportion. The notation a:b = c:d indicates that a/b equals c/d. Such an equality is called a proportion in standard arithmetic terminology. Therefore, the situation described in the question defines a proportion.

Option A:
Variation describes how one quantity changes when another changes, such as direct or inverse variation. It does not specifically refer to the equality of two ratios. Hence, variation is not the term used for a:b = c:d.

Option B:
A proportion is an equation that states two ratios are equal. In the example a:b = c:d, the four terms are said to be in proportion. This matches exactly the relationship described by the question, so proportion is the correct name.

Option C:
Commission is a fee or percentage earned on sales or transactions. It belongs to commercial arithmetic rather than ratio equality. Since the question is about two ratios being equal, commission is irrelevant.

Option D:
Percentage is a way to express a number per hundred, such as 30%. Although percentages are related to ratios, the specific term used when two ratios are equal is proportion, not percentage. Therefore, this option is not correct.

An Institutional Development Plan is a strategic document that lays out the university’s long-term goals and priorities. It includes milestones, timelines and estimates of resources required. Funding schemes such as RUSA often demand such a plan to align grants with clear objectives. Hence, the missing word is “Development.”

Option A:
Dining plans relate to food services or hostel mess arrangements and do not encompass academic and infrastructural strategy. Therefore, this option is not appropriate.

Option B:
Development emphasises growth and improvement in teaching, research and infrastructure. This aligns perfectly with the idea of a strategic institutional plan described in the stem.

Option C:
Parking plans concern vehicle management and campus traffic and are operational, not strategic at the institutional level. Thus, this option is not suitable.

Option D:
Festival plans are short-term event plans and cannot substitute for a comprehensive multi-year development strategy, so this option is incorrect.

Venn diagrams use overlapping regions, typically circles, to show how different classes or sets relate to one another. By shading or marking areas of these diagrams according to the premises, one can visually check whether a proposed conclusion is forced. This method is standard in examining the validity of categorical syllogisms. Therefore the diagrams described in the stem are called Venn diagrams.

Option A:
Option A, flow charts, represent sequential steps, decisions and processes, often in computer science or management contexts. They are not designed to depict class inclusion and exclusion in the way needed for syllogistic reasoning.

Option B:
Option B, decision trees, model branching choices and outcomes, particularly in decision analysis and probability. While they can involve logical structure, they do not primarily illustrate class relationships among terms.

Option C:
Option C is correct because Venn diagrams were specifically developed to handle set-theoretic relationships, which align neatly with categorical propositions. Their overlapping circles allow us to see intersections, unions and complements, making them ideal for testing syllogisms.

Option D:
Option D, matrices, can organise numerical or logical information, but they are not the conventional visual tool for representing class inclusion patterns in introductory logic.

The UNFCCC sets the broad goal for international efforts to address climate change. Its objective is to stabilise greenhouse gas concentrations in the atmosphere at a level that avoids dangerous anthropogenic interference with the climate system. This implies achieving a balance where emissions and removals are compatible with environmental and socio-economic resilience. Therefore, the statement about stabilisation at a non-dangerous level correctly reflects the convention’s primary aim.

Option A:
Option A is incorrect because the convention does not demand complete elimination of fossil fuels within a short time frame. Instead, it calls for gradual, cooperative efforts to limit and reduce emissions.

Option B:
Option B is correct as it summarises the key wording of the convention’s objective. It highlights both the need to control atmospheric concentrations and the idea of preventing dangerous, rather than all, human influences on climate.

Option C:
Option C is incorrect since immediate equal per capita emissions are not mandated. While equity is an important principle, operational commitments vary by country and evolve over time.

Option D:
Option D is incorrect because the UNFCCC does not explicitly ban trade in oil and coal. It focuses on emission control, adaptation and financial support mechanisms rather than on direct trade prohibitions.

Statements A, B, C and E together describe the standard components of a research proposal. A proposal normally states the problem and background, sets out objectives or hypotheses, explains sampling and procedures in the methodology and includes a targeted review of literature to justify the work. Statement D is false because ethical issues are especially important when human participants are involved and should be explicitly addressed. Thus, the only correct combination is the one that includes A, B, C and E and excludes D.

Option A:
Option A is incomplete because it omits statement E, which recognises the important role of literature review in situating the proposed study. Without E, the proposal appears disconnected from previous work, so this combination does not cover all the correct elements.

Option B:
Option B includes B, C and E but leaves out A, thereby failing to mention the need for a clear problem statement and background. Since a well-defined problem is a core feature of any proposal, the omission of A prevents this option from being correct.

Option C:
Option C contains A, C and E but omits B, ignoring the statement that objectives, questions or hypotheses should be outlined. Without B, the proposal lacks clearly articulated aims, so the combination is incomplete.

Option D:
Option D is correct because it assembles all true statements and leaves out D, which wrongly implies that ethical considerations can be ignored in proposals involving human participants. It aligns with standard expectations from funding agencies and ethics committees.

A worm is a stand alone piece of malware that reproduces itself and actively seeks new systems to infect, often exploiting vulnerabilities in network services. Unlike viruses, worms do not need to attach to existing files to spread. Their rapid propagation can consume bandwidth and cause network slowdowns or outages. Hence, the malware described in the stem is a worm.

Option A:
Option A, Trojan horse, appears to be legitimate software but contains hidden malicious functions; it does not typically self replicate across networks.

Option B:
Option B, spyware, secretly monitors user activity but does not necessarily propagate automatically to other machines.

Option C:
Option C, adware, focuses on displaying unwanted advertisements and may not include autonomous spreading mechanisms.

Option D:
Option D is correct because worms are defined by their ability to self replicate over networks without attaching to host files, matching the description in the question.

Statements A, B, C and E are correct because female education influences fertility, education builds environmental awareness, integrated curricula illuminate population–resource linkages and lifelong learning helps people adjust to changing environmental and economic conditions. D is wrong, since education clearly shapes demographic behaviour and environmental choices, and F is wrong because literacy and numeracy underpin informed participation. Thus, the correct combination includes A, B, C and E and excludes D and F.

Option A:
Option A is incorrect because it omits E, thereby ignoring how learning beyond formal schooling contributes to adaptation in a changing environment and labour market. Without E, the picture of education’s role remains incomplete.

Option B:
Option B is incorrect as it accepts D, which denies education’s influence on demographic and environmental outcomes. Including D runs counter to a large body of demographic and environmental education research.

Option C:
Option C is correct since it gathers the four statements that reflect accepted linkages between education, population and environment while rejecting the two that minimise or misrepresent education’s role. It captures both formal and lifelong learning dimensions.

Option D:
Option D is incorrect because it accepts F and omits A. F wrongly claims that basic skills are irrelevant for decision-making, while excluding A ignores one of the most robust findings about female education and fertility.

Statements A, B and D are correct because they describe the nature of e-waste, risks of informal recycling and goals of proper e-waste management. E-waste is a hazardous waste stream due to heavy metals and persistent organic pollutants in discarded electronics. Informal recycling with open burning or acid leaching exposes workers and the environment to toxics. EPR and related policies aim to promote organised collection, safe recycling and sound disposal. Statement C is incorrect because EPR places responsibility primarily on producers, often shared with other actors, not only on consumers.

Option A:
Option A is incorrect because it omits statement D, which is also true. While A and B correctly describe what e-waste is and why informal recycling is risky, leaving out D ignores the role of policy frameworks in promoting safe collection and recycling. Therefore, this option lists only part of the full set of correct statements.

Option B:
Option B is correct because it includes exactly those statements that accurately represent e-waste management: the hazardous nature of e-waste, the dangers of informal recycling and the importance of organised systems and policies. It also excludes statement C, which wrongly assigns responsibility only to consumers. Hence this option reflects the complete and accurate combination.

Option C:
Option C is incorrect because it treats B and C as the only correct statements. Although B is true, C misinterprets EPR by ignoring producer responsibility and the shared but differentiated roles of other stakeholders. The exclusion of A and D further weakens this option.

Option D:
Option D is incorrect as it includes all four statements and thereby accepts C as correct. Since C incorrectly defines EPR, any combination that retains it cannot represent the correct set of statements. This option also fails to distinguish between accurate and inaccurate descriptions of responsibility.

Statements A, B, C, D and F are correct on taxes, subsidies, permits, policy mixes and valuation. Statement E is wrong because economic instruments are intended to reduce pollution when designed well. Therefore A, B, C, D and F only is correct.

Option A:
Option A is incomplete because it omits F.

Option B:
Option B is correct because it includes A, B, C, D and F and excludes E.

Option C:
Option C is incorrect because it includes E (false).

Option D:
Option D is incorrect because it includes E (false) and omits C.

Chart creation in a spreadsheet involves selecting data and generating graphical representations such as bar charts or pie charts. This helps users visualise trends and comparisons more easily than raw numbers. ICT literacy includes understanding how to create and interpret such charts. Therefore, the appropriate term is chart creation.

Option A:
Option A is correct because creation describes the process of generating new charts from data, which is the focus of the stem.

Option B:
Option B, sorting, rearranges data according to certain criteria but does not produce graphs.

Option C:
Option C, filtering, temporarily hides certain rows to focus on subsets of data, again without generating visuals.

Option D:
Option D, validation, ensures that data entry follows rules and is not concerned with graphing.

In the typical governance structure of Indian universities, the Academic Council is recognised as the principal academic body. It approves syllabi, examination schemes and other academic regulations, so the missing word in the stem must be “Academic.”

Option A:
Option A is correct because “Academic Council” is the standard statutory name used in university Acts and ordinances for the body that takes decisions on teaching and examination matters.

Option B:
Option B is incorrect since a Finance Council or committee focuses on budgeting and resource allocation rather than academic policy.

Option C:
Option C is wrong because a Sports Council deals with games and physical education activities, not with syllabi or exam regulations for all programmes.

Option D:
Option D is incorrect as a Works Council or works committee would look after construction or maintenance issues and is unrelated to the academic functions mentioned in the stem.

The positions of the letters are Z(26), X(24), U(21) and Q(17). The decreases between them are −2, −3 and −4, which form an increasing sequence of negative steps in magnitude. The next step should be −5, giving 17 − 5 = 12, which is the letter L. Hence L uniquely satisfies the pattern of successively larger backward jumps.

Option A:
Option A, O, lies at position 15, which would give a decrease of only 2 from Q. This contradicts the trend of increasing the size of the backward step. Since the differences must grow by 1 each time, O cannot fit the rule.

Option B:
Option B, N, is at position 14, implying a decrease of 3 from 17. This repeats a previous step size instead of extending it to −5. Therefore N does not reflect the evolving pattern of differences.

Option C:
Option C, K, corresponds to position 11, giving a drop of 6 from Q. This overextends the next decrement beyond what the sequence suggests. Because the model clearly shows steps of −2, −3, −4, then −5, moving to −6 breaks the logic.

Option D:
Option D is correct because L, at position 12, produces the required decrease of 5 from 17. It aligns with the systematic growth of the backward interval. By respecting the exact structure of the differences, L is the only consistent next term.

Statements A, B, C and D identify key error sources in surveys, and F points to one mitigation strategy. A is true because coverage error arises when parts of the population are missing from the frame, and B correctly defines non-response error. C is accurate in linking measurement error to poor wording or misunderstanding, while D recognises that different modes of administration can affect responses. F is also true since repeated contacts and follow-ups can reduce non-response, whereas E is false because social desirability bias can distort answers and undermine validity.

Option A:
Option A omits statement F, thereby failing to recognise a practical method for reducing non-response error. Although A, B, C and D are correct, the lack of F makes the option less complete in terms of both diagnosis and remedy.

Option B:
Option B leaves out statement A, ignoring the important concept of coverage error, which can prevent some population members from being sampled at all. Without A, the picture of survey validity threats is incomplete, so this option is not acceptable.

Option C:
Option C excludes statement B, neglecting the impact of non-response error on survey conclusions. Even though it includes A, C, D and F, missing B means the combination does not cover all the major threats listed.

Option D:
Option D is correct because it includes A, B, C, D and F, summarising coverage, non-response, measurement and mode effects as well as follow-up strategies. It excludes E, which wrongly claims that social desirability bias has no effect on validity. Therefore, this combination contains all and only the true statements.

Statements A, B and D correctly explain the role of library and learning resources. Statement A is true because libraries are central to academic work by providing diverse scholarly materials. Statement B is correct as digital resources and remote access facilities allow users to consult materials from outside the campus. Statement D is also true since collection development and user orientation are key elements of good library management. Statement C is false because students are primary users of academic libraries along with faculty and researchers. Therefore, A, B and D together form the correct combination.

Option A:
Option A is incorrect because it includes only A and B and omits D, overlooking the importance of proactive management and user services in maintaining the effectiveness of libraries.

Option B:
Option B is incorrect because it pairs A with D but leaves out B, thereby failing to mention the transformative role of digital access in modern library services.

Option C:
Option C is incorrect because it combines B and D and excludes A, not explicitly acknowledging that the basic purpose of a university library is to support teaching and research through resource provision.

Option D:
Option D is correct because it groups all three true statements and excludes C, which wrongly restricts services to faculty and ignores students as key beneficiaries.

A ratio scale possesses all the properties of an interval scale—equal units and meaningful differences—but also includes a true zero point that indicates the absence of the measured attribute. This allows researchers to say that one score is twice or half another in a meaningful way, as in weight or height. Because of these features, ratio scales support the full range of mathematical operations. Thus, the scale described in the stem is correctly called the ratio scale.

Option A:
Ordinal scales allow ranking of cases but do not guarantee equal intervals between ranks, nor do they have a true zero. Numbers indicate order only, not the magnitude of differences, so ordinal scale does not match the properties described in the question.

Option B:
Nominal scales provide categorical labels without quantitative meaning or order and have no concept of interval or zero magnitude. They cannot support ratio statements like “twice as much.” Hence, nominal scale is not appropriate here.

Option C:
Interval scales do have equal units, enabling meaningful comparison of differences, but they lack a true zero point, as seen in Celsius temperature. This absence prevents meaningful ratio interpretations, so interval scale falls short of the description given in the stem.

Option D:
Ratio scales, by including a natural zero, make statements like “this object weighs twice as much as that one” legitimate, which is exactly the property highlighted in the question. This confirms ratio as the correct answer.
