UGC NET Questions (Paper – 1)

Phenomenology is a qualitative research approach that aims to understand and describe how individuals experience a particular phenomenon from their own perspective. It focuses on the meanings, feelings and structures of consciousness associated with those experiences. Researchers often conduct in-depth interviews and then analyse the transcripts to identify common themes that constitute the “essence” of the phenomenon. Because the stem refers to describing the essence of lived experiences, it clearly points to phenomenology.

Option A:
Ethnography involves prolonged engagement in a cultural or social setting to understand norms, values and practices of a group. While it also uses qualitative data, its emphasis is on culture rather than on the essence of individuals’ experiences of a specific phenomenon. Therefore, ethnography is not the correct answer here.

Option B:
Phenomenology requires researchers to bracket or set aside their own assumptions as far as possible so that participants’ descriptions can be examined in a fresh way. The analysis aims to distil invariant structures that characterise the phenomenon across different individuals. This detailed focus on lived experience aligns precisely with the description in the stem, confirming phenomenology as the right completion.

Option C:
Grounded theory, although qualitative, seeks to generate a theory that explains processes or interactions and is less focused on describing the essence of experience. Its primary goal is explanatory theory rather than phenomenological description. Hence, grounded theory does not fit the stem.

Option D:
Case study research examines a bounded case or cases in depth, integrating various sources of data such as documents, interviews and observations. It may use phenomenological insights but is defined by its focus on the case unit rather than the essential structure of a phenomenon across individuals. Consequently, case study is not the best option here.

The starting letters W, T, Q and N occupy positions 23, 20, 17 and 14, decreasing by 3 each time. Each term after the starting letter gives the next three consecutive letters. Continuing this rule, the next starting letter is position 11, which is K, and the block from K is KLMN. Thus KLMN preserves both the minus three jump and the four letter consecutive structure.

Option A:
Option A is correct because K is exactly three positions before N, and the letters L, M and N follow consecutively. It continues the steady backward movement of the starting letters and keeps each group a simple sequence of four adjacent letters. This is fully consistent with the pattern in the given series.

Option B:
Option B, LMNO, starts at L, which is only two positions before N, and therefore changes the step size from minus three to minus two. This inconsistency in the backward jump breaks the arithmetic pattern underpinning the sequence. As a result, LMNO cannot be the correct next term.

Option C:
Option C, PQRS, goes forward from N instead of backward, reversing the direction of the starting letters. The series does not exhibit any forward jumps in its current segment, so PQRS does not align with the logic of the pattern.

Option D:
Option D, UVWX, also represents a forward jump, returning to letters that appeared earlier in the extended alphabetic ordering. It fails to continue the recorded progression of starting letters moving leftward by three positions. Hence UVWX is not a valid continuation.

Statements A, C and D correctly describe multiple ecosystem services of urban green spaces. Vegetation can reduce heat island effects, enhance air quality, provide habitats and extend greenery through roofs and walls. Statement B is incorrect because urban green spaces are recognised for supporting mental health, recreation and social interaction. Hence the combination that includes A, C and D while excluding B is the correct answer.

Option A:
Option A is incorrect because it includes only A and C and leaves out statement D. While A and C are true, D is also a correct statement about green roofs and walls contributing to urban greening and climate adaptation. Omitting a true statement makes this option incomplete.

Option B:
Option B is incorrect because it treats B as correct along with A and C. Statement B wrongly denies the psychological and recreational benefits of green spaces, which are well documented in urban planning and public health literature. Including this false statement invalidates the option.

Option C:
Option C is correct because it groups exactly the three accurate statements A, C and D and excludes the one false statement B. It reflects a rounded understanding of how urban green infrastructure contributes to cooling, air quality and biodiversity as well as innovative building-level greening.

Option D:
Option D is incorrect because it accepts B, C and D. The presence of B, which incorrectly claims no role of green spaces in mental health and recreation, makes the overall combination wrong even though C and D are true.

Statements A, B and D are correct, while C and E are false. Advaita Vedānta extends Nyaya’s four pramāṇas by adding arthāpatti and anupalabdhi, leading to a six-pramāṇa list that is a standard exam item. Not all Vedānta schools reduce these two to other pramāṇas; some take them as distinct, so C misrepresents the range of views. Nyaya keeps to four pramāṇas and does not exactly match the Advaita list, making E wrong. UGC NET indeed asks which systems accept more than four pramāṇas, justifying D. Hence A, B, D only is the correct set.

Option A:
Option A is incomplete because it omits D, ignoring the exam angle that the stem explicitly mentions. A, B only therefore does not fully answer the question.

Option B:
Option B is incorrect since it leaves out B and includes only A and D, losing the detail that arthāpatti and anupalabdhi are the two additions. A, D only thus provides an incomplete picture.

Option C:
Option C is wrong as it includes E, which falsely equates Nyaya’s pramāṇa list with Advaita’s, and leaves out A, so B, D, E only mixes true and false statements.

Option D:
Option D is correct because it groups all and only the true statements, capturing both the doctrinal expansion and the exam relevance while excluding C and E, which misstate the positions of Vedānta and Nyaya.

Statements A, B and C accurately summarise core ideas of cryptography, encryption and decryption. They show how information is transformed and restored using algorithms and keys. Statement D is dangerously false because private keys must be kept secret; sharing them openly destroys security. Thus, the correct answer is the combination A, B and C only.

Option A:
Option A is incorrect because it lists only A and B as correct, leaving out C. Statement C is also correct, since decryption reverses encryption to recover plaintext. Excluding C gives an incomplete picture of the cryptographic process.

Option B:
Option B is incorrect because it groups A, C and D as correct, thereby accepting D. Statement D contradicts the requirement to keep private keys secret and would compromise secure communication.

Option C:
Option C is correct because it recognises that protecting, encrypting and decrypting data are the three linked components specified in A, B and C. It excludes the unsafe recommendation in D.

Option D:
Option D is incorrect because it includes B, C and D only, omitting A and accepting D. This both weakens the conceptual definition and endorses insecure behaviour.

The BCC field, or blind carbon copy, hides the listed addresses from other recipients of the email. This allows the sender to keep certain recipients confidential while still sharing the message. It is often used in group communications to protect privacy. Therefore, the blank should be filled with BCC.

Option A:
Option A, CC, reveals all listed addresses to each recipient and does not provide confidentiality.

Option B:
Option B is correct because BCC is specifically designed to send hidden copies, aligning exactly with the situation described.

Option C:
Option C, Reply, is an action taken on a received message, not a header field for specifying recipients in the original mail.

Option D:
Option D, Sent, is a folder where outgoing messages are stored and has no relation to secret recipients.

Statement D is wrong because no single method can be assumed to answer all research questions adequately in every context. Different questions may require different kinds of data and perspectives. Statements A, B, C and E are correct: interviews provide depth, questionnaires can reach large samples, observation records behaviour in context and multiple methods can triangulate findings. Thus, D alone contradicts good methodological practice.

Option A:
Option A is correct because it isolates D as the only statement that misrepresents data collection practice. It accepts that diverse tools have complementary strengths and that combining them can increase credibility. This option is consistent with the idea of methodological pluralism in research.

Option B:
Option B is incorrect because it adds A to the list of wrong statements, even though A correctly describes the strength of interviews in capturing rich experiential data. Misclassifying A as wrong underestimates the value of qualitative interviewing.

Option C:
Option C is also wrong because it treats C and D as jointly wrong, despite C correctly stating that observation can capture natural behaviour. By labelling observation as incorrect, this option ignores a fundamental method in field research.

Option D:
Option D is incorrect because it groups B with D and E and thereby mislabels B and E as wrong. Both B and E are accurate descriptions of how questionnaires and multiple methods function in research, so their inclusion among “wrong” statements makes this option invalid.

SQAAF is intended to offer a holistic framework of quality indicators and processes so that schools can be assessed on learning outcomes, pedagogy, infrastructure and governance, and use the feedback for continuous improvement rather than mere ranking or punishment.

Option A:
This option reduces quality to exam marks alone, which NEP explicitly criticises as too narrow an indicator of school performance.

Option B:
This option correctly reflects SQAAF’s purpose as a comprehensive framework for assessing and improving overall school quality.

Option C:
Linking teachers’ salaries only to student marks is not the objective of SQAAF and could create perverse incentives.

Option D:
Selecting schools for closure based purely on infrastructure size ignores learning and process indicators and is not what NEP proposes for SQAAF.

Converting 2748 to base 7 requires repeated division by 7 and recording remainders. Performing this process yields digits that, read from last remainder to first, give 11004₇. We can verify by expanding 11004₇ as 1×7⁴ + 1×7³ + 0×7² + 0×7¹ + 4×7⁰, which equals 2401 + 343 + 0 + 0 + 4 = 2748. Hence 11004₇ is the correct base-7 representation, making option D correct.

Option A:
Option A has a similar-looking pattern of digits but a different combination of powers of 7. When expanded, it produces a decimal value slightly different from 2748. Therefore, it cannot represent 2748 exactly in base 7.

Option B:
Option B uses a larger digit in one of the higher positions, giving a decimal value greater than 2748 when converted. Since the expansion does not match 2748, this base-7 number is not correct.

Option C:
Option C uses a different arrangement of digits, yielding a smaller decimal value than 2748. Its place value expansion does not sum to 2748, so it is not an equivalent representation.

Option D:
Option D expands precisely to 2748 using the weights 7⁴, 7³ and 7⁰ with digits 1, 1 and 4 respectively and zeros in the remaining places. This correspondence between expansion and given decimal number ensures that 11004₇ is the only correct representation among the options.

The decimal 0.25 equals 1/4, which is 2^-2 in terms of powers of 2. In binary, 0.01₂ means 1 in the 2^-2 place and 0 in the 2^-1 place, giving 1/4. Hence 0.01₂ correctly represents 0.25 in decimal.

Option A:
Option A, 0.1₂, represents 1×2^-1 = 1/2, which is 0.5 in decimal. This is greater than 0.25 and unsuitable as its representation.

Option B:
Option B is correct because it places a 1 in the 2^-2 position, giving exactly 1/4. No other fractional positions contribute, so the value is precisely 0.25.

Option C:
Option C, 0.11₂, gives 1/2 + 1/4 = 3/4, which is 0.75 in decimal. This is a much larger value and cannot be equal to 0.25.

Option D:
Option D, 0.001₂, equals 1×2^-3 = 1/8 or 0.125. This is smaller than 0.25 and therefore not the correct representation.

Statements A, B, C and D correctly summarise standard relationships on the traditional square of opposition, whereas E is false. Contradictory propositions cannot both be true and cannot both be false, and contraries cannot both be true but may both be false. “All S are P” versus “No S are P” are contraries, while “All S are P” versus “Some S are not P” are contradictories. The pair “Some S are P” and “No S are P” are also contradictories, not contraries, making E the only wrong statement.

Option A:
Option A is incorrect because it includes D as wrong along with E, but D accurately states a classic contradictory pair. Treating both D and E as wrong would misrepresent the structure of the square of opposition.

Option B:
Option B is also wrong since it marks C as wrong along with E, even though C correctly identifies “All S are P” and “No S are P” as contraries. C and E only therefore misclassifies a true statement as false.

Option C:
Option C is correct because it isolates E, the misidentified pair of contraries, as the sole incorrect statement and leaves the accurate descriptions in A, B, C and D untouched. This matches standard logic used in UGC NET preparation.

Option D:
Option D is incorrect as it groups C and D with E, thereby wrongly casting doubt on correctly named contrary and contradictory pairs. C, D and E only thus fails to preserve reliable information about AEIO relations.

Content validity concerns whether the items in a test or questionnaire are representative of the entire domain of content they are supposed to measure, such as a course syllabus or topic area. Subject experts often review the instrument to judge whether important areas are adequately sampled. High content validity reduces the chance that important facets of the construct are omitted. Therefore, the coverage-focused validity described in the stem is correctly called content validity.

Option A:
Option A, content validity, is especially important in achievement tests where missing topics can bias scores. When an instrument aligns well with specified learning outcomes or a blueprint, it demonstrates strong content validity, matching the stem exactly.

Option B:
Construct validity addresses whether the instrument truly measures the underlying theoretical construct, based on patterns of relationships with other variables and factor structure. It goes beyond simple content coverage, so it is not the best fit for this question.

Option C:
Criterion-related validity evaluates how well test scores correlate with an external criterion, such as job performance or future grades. It deals with predictive or concurrent accuracy rather than domain coverage. Hence, it is not appropriate here.

Option D:
Face validity refers to the extent to which a test appears to measure what it claims to, based on superficial inspection by users. It does not involve systematic analysis of content coverage, so it is not the correct answer.

Among greenhouse gases emitted by human activities, carbon dioxide contributes the most to anthropogenic global warming in terms of total radiative forcing. It is released mainly from burning fossil fuels, deforestation and industrial processes. Although other gases like methane and nitrous oxide have higher warming potential per molecule, their concentrations and total forcing are lower. Hence, carbon dioxide is regarded as the primary driver of the enhanced greenhouse effect, making option D correct.

Option A:
Option A, nitrous oxide, is a potent greenhouse gas but its atmospheric concentration and total contribution to warming are smaller compared to carbon dioxide. It is significant in agriculture and industry, yet not the largest contributor overall.

Option B:
Option B, methane, has a higher global warming potential than carbon dioxide per unit mass but is present in much lower concentrations. Its total radiative forcing is less than that of carbon dioxide, so it is not the largest contributor to anthropogenic warming.

Option C:
Option C, chlorofluorocarbons, are powerful greenhouse gases and ozone-depleting substances, but due to regulation under the Montreal Protocol, their emissions have declined. Their overall contribution is less than that of carbon dioxide.

Option D:
Option D is correct because carbon dioxide is emitted in very large quantities from energy, transport and land-use change. Its long atmospheric lifetime and cumulative build-up make it the major contributor to human-induced climate change.

Statements A, B, C and E accurately represent key aspects of open access and repositories. Open access removes paywall barriers for readers, some models shift costs to authors or institutions, repositories can host versions of articles and openness can broaden readership and potential citations. Statement D is false because many open access journals are peer reviewed just like subscription journals. Thus, the combination including A, B, C and E while excluding D is correct.

Option A:
Option A is incomplete because it omits E, overlooking the impact of open access on reach and citation, which is often a major justification for choosing this route. Without E, benefits appear limited to access alone.

Option B:
Option B is wrong as it leaves out A and includes only B, C and E. While those are true, excluding A fails to state the central feature that articles are freely accessible to readers.

Option C:
Option C is correct because it gathers the full set of accurate statements about open access models, repositories and potential impact, while rejecting the idea in D that open access means no peer review.

Option D:
Option D is incorrect since it incorporates D and omits B, implying that open access is inherently non-peer-reviewed and ignoring article processing charges as a common funding mechanism.

Statements A, C and D are correct, whereas B is incorrect. A is true because most models of listening describe it as a sequence of receiving, constructing meaning and responding. C is true since what a listener already knows shapes how they interpret new information. D is true as nodding, eye contact and other non-verbal cues show attention and form part of active listening. B is false because hearing is a physiological process of sound reception, whereas listening is a psychological process involving attention and interpretation.

Option A:
Option A includes A and C only and omits D, failing to mention that non-verbal responses are integral to the listening process in interactive communication. Although A and C are correct, the option underplays the response component. Therefore A and C only is incomplete and cannot be accepted.

Option B:
Option B combines A, C and D and excludes B, which wrongly equates hearing and listening. It captures listening as a multi-stage, meaning-making and responsive activity. Because it lists all and only the correct statements, A, C and D only is the right answer.

Option C:
Option C groups C and D only and leaves out A, ignoring the core definition that listening involves receiving messages, not only interpreting and responding. While C and D are true aspects of listening, excluding A means the option does not present a full picture of the process. Hence C and D only is not valid.

Option D:
Option D treats all four statements as correct, including B, which confuses hearing with listening. This misrepresentation of basic concepts makes the combination logically inconsistent. Consequently A, B, C and D cannot be chosen.
