UGC NET Questions (Paper – 1)

Statements A, B, C and E present a coherent picture of how industry relates to environment and sustainable development. Industrialisation can support growth and jobs, but pollution risks arise without safeguards, making cleaner technologies and resource efficiency important. Public disclosure of performance can create reputational incentives to improve compliance. Statements D and F are incorrect because regulations can drive innovation and environmental management systems explicitly support sustainable development goals. Therefore, the combination that includes A, B, C and E only is correct.

Option A:
Option A is correct because it selects all and only the statements that are conceptually sound: A and B describe growth and pollution risks, C stresses cleaner processes and E highlights disclosure as a driver of better performance. It appropriately excludes D, which overstates negative effects of regulation, and F, which ignores SDG linkages. This option aligns with contemporary views on industrial sustainability.

Option B:
Option B is incorrect as it omits statement E, thereby ignoring the role of transparency and public reporting in improving environmental behaviour. While A, B and C are true, leaving out E means the answer set is incomplete. In addition, it does nothing to correct the false notions in D and F.

Option C:
Option C is incorrect because it includes B, C and E but also F, which wrongly claims that environmental management systems are unrelated to SDGs. It also omits statement A, which correctly notes the economic aspect of industrialisation. The presence of F makes this combination logically flawed.

Option D:
Option D is incorrect since it brings together A, C and E with F. Although A, C and E are correct, including F introduces a clearly false statement about the irrelevance of environmental management systems to sustainable development. It also excludes B, which properly recognises pollution risks from poorly regulated industry.

Statements A, B, D and E correctly portray lifelong learning. A is true because universities often run continuing education units. B is true as such centres organise workshops and refresher courses. D is true since recognition of prior learning connects existing skills with further study. E is true because outreach and lifelong learning frequently intersect in community-oriented programmes. C and F are false because lifelong learning is important at all ages and can complement formal degree systems.

Option A:
Option A is incorrect because it omits E and therefore ignores the strong link between community outreach and lifelong learning activities.

Option B:
Option B is correct as it includes A, B, D and E, the four true statements about continuing education, short courses, RPL and outreach, while excluding C and F, which wrongly restrict or oppose lifelong learning.

Option C:
Option C is incorrect because it adds F, which claims incompatibility with formal degrees, and omits A, thus failing to show the institutional anchoring of lifelong learning.

Option D:
Option D is incorrect because it includes C, which limits lifelong learning to retired persons, and omits B, so it does not refer to the range of programmes offered.

A stable interest in learners and positive attitude to the profession are core indicators of teaching aptitude—dispositions that support success in teaching.

Option A:
Mechanical aptitude relates to machines/tools, not interest and attitudes toward teaching learners.

Option B:
Teaching aptitude includes interest, attitude and suitability for teaching roles—matching the stem.

Option C:
Athletic aptitude concerns sports ability, not professional inclination toward teaching.

Option D:
Musical aptitude concerns musical skills/interests, not general teaching suitability.

In basic models of communication,the sender must convert internal thoughts into an external message. This conversion of ideas into language,gestures or images is known as encoding. Without encoding,the message cannot travel through any channel to the receiver. Thus the process described in the stem is correctly termed encoding.

Option A:
Decoding is the opposite operation carried out by the receiver,who interprets the message coming from the sender. It does not refer to the sender choosing words or symbols. Therefore it does not match the description of translating ideas into symbols.

Option B:
Encoding is the stage where the sender decides how best to express their idea so that the receiver can understand. It involves selecting suitable words,tone and non verbal cues. Because the stem emphasises this act of translation,encoding is the most appropriate term.

Option C:
Feedback is the receiver’s response returning to the sender after the initial message has been received and interpreted. It is not the original translation of ideas into message form. Hence feedback cannot be the correct answer here.

Option D:
Filtration refers to selective transmission or suppression of information,often because of organisational or personal factors. It does not describe the basic act of putting ideas into symbols at the point of message creation.

Content validity refers to how well the items in a test or questionnaire sample the full range of the content domain or syllabus that is of interest. Expert judgment is typically used to check whether important topics, cognitive levels and skills are proportionately represented. High content validity indicates that decisions based on test scores are grounded in comprehensive coverage rather than in a narrow subset of material. Since the stem emphasises adequate representation of the entire content domain, content validity is the correct term.

Option A:
Predictive validity concerns the extent to which test scores can forecast future performance on a relevant criterion, such as success in a later course. While important, it does not address whether the items themselves cover the domain sufficiently. Hence, predictive validity does not match the description in the question.

Option B:
Concurrent validity evaluates the degree to which test scores correlate with other measures of the same construct taken at the same time, indicating how well the test aligns with existing indicators. It focuses on agreement with current criteria rather than on syllabus coverage, so it is not the correct completion.

Option C:
Construct validity deals with the theoretical meaning of the test scores and how they relate to broader concepts and other variables, not specifically with the breadth of content coverage. Therefore, construct validity is not appropriate for the stem, which stresses representation of the content domain.

Option D:
Content validity is often ensured by preparing a table of specifications that maps items to objectives and content areas. This process ensures that no critical topic area is neglected, which is exactly what the question is about.

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.
