UGC NET Questions (Paper – 1)

Statements A, C and D are correct, while B and E are false. The post hoc fallacy wrongly infers causation merely from temporal order, ignoring other possible explanations. Because correlation and temporal succession alone are not enough, careful design and control of experiments are needed to eliminate competing causes. UGC NET questions sometimes present arguments that rely on this faulty reasoning and ask candidates to detect the mistake. Post hoc inference is therefore not a valid deductive form, making E incorrect, and the correct set is A, C, D only.

Option A:
Option A is incomplete as it omits D, leaving out the explicit connection to UGC NET question formats. A and C only thus does not satisfy the full requirements of the stem.

Option B:
Option B is wrong since it leaves out A, failing to state explicitly what the post hoc fallacy is, and C and D alone do not identify the fallacy pattern. C and D only therefore cannot be correct.

Option C:
Option C is correct because it captures the definition of the fallacy, the need for better evidence, and its appearance in exam items while excluding B and E, which overstate the power of correlation and treat post hoc as valid deduction.

Option D:
Option D is incorrect as it includes B, thereby wrongly claiming that correlation and temporal succession are always sufficient for causation, and so A, B, C, D only mixes truth with clear error.

Social justice in higher education involves ensuring fair opportunities for historically disadvantaged groups to access and succeed in academic programmes. Reservation policies, scholarships and fee waivers are tools to correct systemic inequalities and barriers. The stem mentions reservation and financial support for marginalised groups, which are classic measures to advance social justice. Therefore, Option B accurately completes the sentence.

Option A:
Social justice frameworks recognise that formal equality may not be enough when groups start from unequal positions. They call for affirmative measures to create more substantive equality of opportunity, which is exactly what the policies described in the question seek to do.

Option B:
Market efficiency focuses on resource allocation based on supply, demand and price signals without necessarily addressing historical exclusion. It may even worsen inequalities if left unchecked, so this option does not match the ethical goal in the stem.

Option C:
Military security concerns defence and protection of national borders and is unrelated to admission and support policies in higher education. Hence, this option is not appropriate here.

Option D:
Automation refers to the use of technology to perform tasks with minimal human intervention. While it can change labour market demands, it is not directly related to reservation or equity measures in higher education.

Population density expresses how many people occupy a given area of land. It is calculated as population divided by land area and is typically reported as persons per square kilometre or square mile. The stem clearly describes this ratio,so density is the correct term. It is a fundamental indicator in demography and planning.

Option A:
Density helps planners compare crowded and sparsely populated regions and understand pressure on land and services,which matches the idea in the stem.

Option B:
Growth refers to change in population size over time,not people per unit area.

Option C:
Mobility is movement of people (migration/commuting),not the spatial ratio described.

Option D:
Structure refers to composition (age/sex etc.),not the per-area measure.

Pull factors are conditions that attract people to a new place. In rural–urban migration, higher wages, better services and perceived opportunities in cities draw migrants. These forces operate alongside push factors that drive people away from origin areas. Therefore, the availability of better jobs and higher wages in cities exemplifies a pull factor.

Option A:
Option A is incorrect because crop failure and drought are classic push factors. They push people out due to hardship rather than attracting them into a new place. They describe conditions at the place of origin.

Option B:
Option B is incorrect because political conflict and violence are push factors that drive people away from their villages due to insecurity. They represent adverse conditions at the origin, not attractions at the destination.

Option C:
Option C is correct since employment opportunities and higher income act as magnets. Migrants choose cities hoping to improve their living conditions through better jobs and wages, which is the essence of a pull factor.

Option D:
Option D is incorrect because land degradation and declining fertility push farmers away from rural areas. These are again problems at the place of origin rather than pull factors in cities.

Social forestry programmes focus on involving local communities in tree planting and management outside traditional forest areas. The objectives include supplying fuelwood,fodder and small timber while improving the environment. The stem mentions planting on community lands and roadsides for local needs,which is a hallmark of social forestry. Therefore social forestry is the correct answer.

Option A:
Social forestry emphasises both livelihood support and ecological benefits such as soil conservation and micro climate improvement. Because the question stresses meeting local needs as well as tree planting,this option aligns closely with the described approach.

Option B:
Industrial forestry is oriented toward large scale timber production,often in monoculture plantations,primarily for industrial use. It is not specifically designed to meet small local subsistence needs,so it does not match the stem.

Option C:
Clear cut forestry refers to a harvesting method in which all or most trees in an area are felled at once. It describes a logging practice rather than a community oriented planting programme.

Option D:
Commercial forestry is driven mainly by profit from wood or other products and may not prioritise local subsistence needs or community participation. Hence it is not the best fit for the concept in the question.

In the carbon cycle, photosynthesis is the key biological process that takes up carbon dioxide from the atmosphere. Green plants, algae and some bacteria use CO2 and water in the presence of sunlight to produce carbohydrates and release oxygen. The carbon is stored temporarily in plant biomass and, through food chains, in other organisms. Thus, photosynthesis acts as a major carbon sink, making Option C the correct answer.

Option A:
Option A is incorrect because combustion of fossil fuels adds carbon dioxide to the atmosphere. It is a carbon source, not a sink, and contributes to climate change.

Option B:
Option B is incorrect since deforestation removes trees that would otherwise absorb CO2. It reduces the capacity of terrestrial ecosystems to act as carbon sinks and often releases stored carbon when biomass is burned or decomposes.

Option C:
Option C is correct as it points to the primary natural mechanism for withdrawing CO2 from the atmosphere. Protecting and enhancing photosynthetic ecosystems is a key strategy for climate mitigation.

Option D:
Option D is incorrect because volcanic eruptions release gases, including CO2, to the atmosphere. They are natural sources of carbon, not processes that remove it.

A scanner is designed to capture images or printed text and translate them into digital data that a computer can store and process. It uses optical sensors to read the physical document and convert it into a bitmap or similar format. This process is central to digitising paper records and images. Hence, the device described in the stem is a scanner.

Option A:
Option A is correct because standard ICT classifications list scanners as input devices that bring external visual information into the computer system. They play an important role in document management and optical character recognition tasks.

Option B:
Option B, printer, is an output device that produces hard copies of digital documents rather than capturing physical documents into the computer. Its direction of information flow is opposite to what is described.

Option C:
Option C, speaker, outputs audio signals from the computer to the user and therefore cannot be used to input printed text or images.

Option D:
Option D, plotter, produces large-scale drawings or graphics on paper and is considered a specialised output device, not an input device.

Statement C is wrong because research questions do not have to be yes/no questions; they may be descriptive, comparative or explanatory in form. Statements A, B, D and E are correct: questions should be clear, hypotheses testable, vagueness leads to design problems and exploratory work may proceed with questions but no formal hypotheses. Therefore, C alone is the incorrect statement here.

Option A:
Option A is wrong because it combines C with D, even though D accurately highlights that vague questions make it difficult to choose appropriate designs and methods. By classifying D as wrong, this option misrepresents a genuine methodological risk.

Option B:
Option B is incorrect because it labels A, which rightly demands clarity and focus, as wrong along with C. This undermines a basic principle of good research question formulation.

Option C:
Option C is correct because it isolates C as the only statement inconsistent with accepted research practice. It acknowledges the diversity of question forms that can guide inquiry.

Option D:
Option D is incorrect because it pairs C with E, wrongly implying that using questions without hypotheses in exploratory work is a mistake. E is actually a true description of how exploratory studies often proceed.

Ethnography involves prolonged engagement with a cultural or social group, often through participant observation and in-depth interviews. The researcher seeks to understand shared meanings, rituals and patterns of interaction from an insider’s perspective. Thick description of the culture is a hallmark of ethnographic work. Therefore, the immersion-based strategy described in the stem is known as ethnography.

Option A:
Grounded theory aims to generate theory from data through constant comparison and theoretical sampling. While it may involve fieldwork, its primary goal is theory construction rather than rich cultural description. Hence, it is not the correct term here.

Option B:
Option B, ethnography, focuses on culture, social practices and collective meanings. The researcher often lives or spends extensive time in the setting to capture natural behaviour. Because the stem emphasises immersion and shared patterns of behaviour, this option is correct.

Option C:
Narrative inquiry concentrates on people’s stories and how they make sense of experiences through narrative form. It does not require long-term immersion in a culture, so it does not match the description.

Option D:
A case study examines a bounded system such as an organisation or programme in depth. While it may overlap with ethnography, it is not defined primarily by cultural immersion and study of shared patterns, so it is not the best completion.

Each term after the first is obtained by doubling the previous term and subtracting 1. We have 3×2−1 = 5, 5×2−1 = 9, 9×2−1 = 17 and 17×2−1 = 33, confirming the rule. Applying it again gives 33×2−1 = 66−1 = 65. Hence, 65 is the correct next term.

Option A:
Option A is 63, which would require subtracting 3 from 33×2, not 1. The series consistently subtracts 1, so altering that constant is unjustified. Therefore, 63 is incorrect.

Option B:
Option B is 64, implying that we simply double 33 and subtract 2. Such a modification has no support from the earlier steps. Thus, 64 cannot match the pattern.

Option C:
Option C equals 65 and follows the rule 33×2−1 exactly. The extended sequence 3, 5, 9, 17, 33, 65 is perfectly consistent with the defined operation. This makes 65 the valid continuation.

Option D:
Option D is 67, which would result from 33×2+1 and introduces addition instead of subtraction. Since all previous transitions subtracted 1, this change breaks the rule. Therefore, 67 is not appropriate.

Statement D is the only wrong statement because instructional design principles discourage overloading slides with text. Slides should support, not replace, verbal explanation and should be concise. Statements A, B and C correctly describe the benefits and cautions of multimedia use, including combining media types, avoiding overuse of effects and maintaining consistent design. Therefore, the option that chooses only D as wrong is correct.

Option A:
Option A is incorrect because it groups A and D as wrong statements. Statement A is correct in describing how multimedia can integrate different forms of content to enhance understanding. Including this true statement in the wrong set makes the option conceptually unsound.

Option B:
Option B is correct because it isolates D as the sole wrong statement. It acknowledges that text-heavy slides are not recommended and that slides should complement the presenter. By accepting A, B and C as accurate, this option matches good practice in multimedia presentations.

Option C:
Option C is incorrect because it lists A, B and D as wrong statements. Both A and B are valid descriptions of multimedia use and potential distractions. Since only D is actually wrong, this combination misclassifies true statements.

Option D:
Option D is incorrect because it groups B, C and D as wrong statements. Statements B and C are correct in warning against excessive effects and in promoting consistent design. Including them with the false statement D prevents this option from being the right answer.

Noise is defined as any unwanted interference that distorts or obscures the message as it travels through the channel. Loud corridor chatter,traffic or construction sounds can cover parts of the teacher's voice,making the lecture hard to follow. The stem clearly refers to such disturbances,so noise is the correct completion.

Option A:
Feedback is purposeful information about understanding and usually helps improve communication,so it is quite different from unwanted disturbance.

Option B:
Channel is the medium that carries the message,such as air or a sound system,and is not itself the disturbance. A channel may be affected by noise,but the two concepts are distinct.

Option C:
Message denotes the content being taught,not the interfering sounds that disrupt it,so it cannot fill the blank.

Option D:
In communication theory,noise can be physical,psychological or semantic,but in this case it is physical noise affecting hearing. Recognising noise helps communicators take steps like closing windows or using microphones to reduce its impact. This explanation fits Option D exactly.

Intrapersonal communication occurs entirely within a single individual,where that person is both sender and receiver. Silent planning before speaking is a classic example of such inner dialogue. No external audience is directly involved,so the process remains intrapersonal.

Option A:
Intrapersonal communication includes self evaluation,daydreaming and internal rehearsal of messages. These activities shape how one later communicates with others. The stem focuses on exactly this kind of inner planning,making this option appropriate.

Option B:
Interpersonal communication requires at least two distinct people sending and receiving messages,which is not the case when communication happens only inside the mind.

Option C:
Group communication refers to interaction among several individuals,usually to accomplish a task,so it cannot describe solitary thinking.

Option D:
Mass communication involves institutional sources sending messages through media to large,dispersed audiences and is unrelated to private self talk.

Statements A, B and D correctly describe the role of MIS in governance. A is true because MIS tools integrate data to inform decisions about programmes and resources. B is correct since enrolment, performance and financial data allow management to monitor trends and effectiveness. D is also true as reports from MIS help leaders assess progress on strategic plans and quality benchmarks. Statement C is false because data privacy and security are critical when handling personal and institutional information on digital platforms. Thus, A, B and D only are correct.

Option A:
Option A is incorrect because it lists only A and B and omits D, which highlights how MIS outputs are used to follow strategic and quality-related goals. Without D, the link between data and strategic leadership is weakened.

Option B:
Option B is incorrect because it selects B and D only and leaves out A, which sets out the overarching idea of evidence-based decision-making supported by MIS. Excluding A makes the picture less coherent.

Option C:
Option C is correct because it combines all the true statements about MIS roles while rejecting C, which wrongly dismisses privacy and security concerns. It reflects both the utility and the responsibilities associated with digital data systems.

Option D:
Option D is incorrect because it treats every statement as correct, thereby accepting C, which contradicts basic principles of responsible data management.

Statements A, B, C, D and F are correct as they show health impacts, sensitive-zone regulation, sources of noise and technical or planning measures for control. Statement E is false because chronic noise exposure is associated with cardiovascular effects such as hypertension. Therefore, the combination that includes A, B, C, D and F and excludes E is correct.

Option A:
Option A is incorrect because it omits F and so ignores practical approaches to noise control such as silencers, design and enforcement, even though those are essential for mitigation.

Option B:
Option B is incorrect since it leaves out D, underplaying the importance of traffic, construction and industry as major noise sources in urban environments.

Option C:
Option C is incorrect as it omits A, thereby failing to acknowledge the direct hearing damage that can result from high noise exposure, which is a primary concern in noise pollution.

Option D:
Option D is correct because it assembles all true statements about impacts, sources, regulatory tools and control measures, while rejecting the claim that cardiovascular effects are absent.
