UGC NET Questions (Paper – 1)

The differences between successive terms are 4, 6, 8 and 10. These differences form an arithmetic pattern increasing by 2 each time. The next difference should therefore be 12. Adding 12 to the last term 33 gives 33 + 12 = 45, which extends the series consistently.

Option A:
Option A gives 43, corresponding to a difference of 10 from 33, which simply repeats the last difference rather than increasing it. This breaks the second-level arithmetic progression. Hence, 43 does not follow the intended pattern.

Option B:
Option B yields 45, which is 12 more than 33 and maintains the difference sequence 4, 6, 8, 10, 12. This preserves the clear, systematic growth at the level of differences. Therefore, 45 is the correct next term in the series.

Option C:
Option C suggests 47, which would produce a difference of 14 and jump beyond the expected increment. This destroys the steady increase by 2 units in the differences. Thus, 47 is not a valid continuation.

Option D:
Option D offers 49, giving a difference of 16 from 33 and deviating even further from the planned pattern. Including 49 would make the sequence erratic. Therefore, 49 cannot be regarded as correct.

Flipped classrooms invert the traditional pattern of lecture in class and homework at home. ICT makes it feasible to provide recorded lectures, interactive modules and readings online for self-paced study before class. Classroom meetings can then focus on application, clarification and collaborative tasks. This shift supports active learning and higher-order thinking.

Option A:
Option A correctly illustrates how ICT extends learning beyond classroom walls and frees up in-person time for richer engagement. It aligns with common implementations in universities and schools.

Option B:
Option B describes the traditional teacher-centred lecture approach, which the flipped model explicitly seeks to modify.

Option C:
Option C contradicts the idea of ICT-supported pedagogies; banning technology removes the means for flipping content delivery.

Option D:
Option D limits learning to library spaces and ignores the role of pre-class digital engagement and in-class interaction central to flipping.

Kinesics is the study of body movements such as gestures,posture and facial expressions that convey meaning. The stem mentions exactly these elements used alongside speech. Therefore kinesics is the correct term for this cluster of non verbal cues.

Option A:
Kinesics includes both conscious and unconscious movements that modify or replace verbal messages,making this option accurate.

Option B:
Proxemics relates to use of physical space and distance between communicators,not to body movements themselves.

Option C:
Oculesics focuses specifically on eye behaviour such as gaze and eye contact.

Option D:
Chronemics examines the use of time and pauses,which is different from movements.

Generalisability concerns the extent to which the findings of a particular study can be validly extended beyond the specific sample, setting and time in which the data were collected. High generalisability implies that similar results would likely be obtained in other contexts with comparable conditions. It is closely linked to external validity, which evaluates how well study results apply in real-world situations. Therefore, a statement about how far results may be applied elsewhere refers to the generalisability of the findings.

Option A:
Reliability addresses the consistency of measurement within the study and does not by itself indicate whether results can be extended to other populations or settings. A measure can be reliable in one context but may not generalise to different groups. Hence, reliability is not the correct completion.

Option B:
Generalisability is influenced by factors such as sampling method, sample size, and ecological validity of the research setting. Researchers often discuss limitations on generalisability to avoid overstating the applicability of their results. These concerns match the description in the stem.

Option C:
Standardisation involves using uniform procedures and conditions when administering instruments or conducting experiments, which supports reliability and fairness but is not the same as extending findings to other contexts. Therefore, standardisation is not the best answer.

Option D:
Objectivity refers to freedom from researcher bias in collecting and interpreting data, ensuring that findings are based on evidence rather than personal preferences. While it contributes to the credibility of results, it does not directly describe their scope of application, so objectivity is not appropriate here.

Statements A, B and C correctly outline important aspects of email netiquette and safety, whereas statement D is clearly incorrect. A meaningful subject line, avoidance of sharing sensitive data and respectful language are all best practices in email communication. In contrast, attachments from unknown senders can carry malware or phishing attempts and are not automatically safe. Thus, the combination containing A, B and C only is the correct set of statements.

Option A:
Option A is incorrect because it includes only A and B and omits C. While A and B are true, C is also correct in emphasising the role of respectful and concise language in email netiquette. Leaving out C means the option does not include all correct statements.

Option B:
Option B is incorrect because it groups A, C and D together as correct. Statement D is wrong, since unknown attachments may contain security threats despite email protections. Including D alongside A and C makes this combination partially false.

Option C:
Option C is correct because it brings together A, B and C, which are all valid guidelines for safe and polite email use. It excludes the dangerous advice in statement D about trusting all attachments. This balance between clarity, caution and courtesy matches recommended email practices.

Option D:
Option D is incorrect because it treats B, C and D as correct, thus accepting D. Although B and C are true, statement D misleads users into ignoring basic security precautions. A correct option must reject that claim.

Statements A, B, C and E are correct, describing planning, social, ecological and analytical dimensions of urban resilience. Integrating risk into planning, using social protection, restoring ecosystems and conducting multi-hazard assessments all strengthen cities’ ability to cope with climate impacts. D is wrong because institutions and communities are central to resilience, and F is wrong as community participation improves relevance and ownership of plans. Therefore, A, B, C and E only is the correct combination.

Option A:
Option A is incorrect because it omits E, thereby ignoring the importance of multi-hazard assessments in understanding combined risks. Without E, the analytical basis of resilience planning is not fully captured.

Option B:
Option B is incorrect as it includes only B, C and E and leaves out A, which is fundamental in stating that planning and infrastructure must integrate climate risk. Excluding A weakens the description of what makes a city climate-resilient.

Option C:
Option C is incorrect since it accepts F and omits B. Accepting F denies the value of community participation, while dropping B neglects the role of social protection for vulnerable groups.

Option D:
Option D is correct because it combines all the true statements and excludes D and F, which narrow resilience to physical assets and dismiss participation. It reflects the multi-dimensional approach to urban climate resilience emphasised in this unit.

The series follows an alternating pattern of multiplying by 2 and then subtracting 2. Starting from 5, we get 5 × 2 = 10, then 10 − 2 = 8, then 8 × 2 = 16 and then 16 − 2 = 14. Continuing this pattern, the next step after 14 should be to multiply by 2, giving 14 × 2 = 28. This preserves the established alternation of operations.

Option A:
Option A, 18, could arise from adding 4 to 14, but there is no consistent rule of adding 4 in the earlier part of the series. It introduces a new pattern not supported by previous terms.

Option B:
Option B, 20, might seem plausible as adding 6 to 14, yet such an operation is not part of the alternating multiply by 2 and subtract 2 rule evident in the earlier sequence.

Option C:
Option C, 24, equals 16 + 8 or similar combinations but does not correspond to the prescribed alternation of operations applied directly to the preceding term.

Option D:
Option D directly applies the observed pattern, maintaining the multiply by 2 step after a subtract step. It ensures that the structure of alternating operations continues without disruption, making 28 the correct next term.

Statement C is the only wrong statement because symmetric-key encryption requires the same secret key at both ends, not different keys. A rightly states that encryption transforms plaintext into ciphertext using an algorithm and key, B is correct about protecting confidentiality in transit, and D reflects the use of encryption in secure web protocols such as those used for online payments. Therefore the combination that selects only C as wrong is the correct answer.

Option A:
Option A is incorrect because it treats both B and C as wrong. B accurately describes the role of encryption in protecting confidentiality during transmission, so grouping it with the false statement C misidentifies a true property as wrong. This option therefore overstates the set of wrong statements.

Option B:
Option B is correct as it isolates C, which mischaracterises symmetric-key encryption as using different keys. By recognising that A, B and D are standard descriptions of encryption and that only C is false, this option precisely matches the requirement to select the wrong statement(s).

Option C:
Option C is incorrect because it considers A and C together as wrong. A is a fundamental definition of encryption, so including it among wrong statements contradicts basic ICT knowledge. Mixing one false statement with one true statement makes this combination invalid.

Option D:
Option D is incorrect because it treats C and D as wrong even though D correctly notes that secure web protocols rely on encryption. Since only C is wrong, adding D expands the set of wrong statements beyond what the question requires.

Statements A, B, C and D correctly describe the four standard categorical forms, while E is false. A-propositions are indeed “All S are P”, E-propositions “No S are P”, I-propositions “Some S are P” and O-propositions “Some S are not P”. I-propositions are particular, not universal, so they do not express universal affirmation. Therefore the set of all and only true statements is A, B, C, D only.

Option A:
Option A is correct because it includes exactly those four statements that match the standard AEIO scheme and excludes E, which wrongly labels an I-proposition as universal. This option fully represents textbook terminology used in UGC NET preparation.

Option B:
Option B is incorrect since it omits D, leaving out the correct form of the O-proposition, and so A, B, C only does not list all true statements. It is therefore incomplete with respect to the question stem.

Option C:
Option C is wrong because it drops C, the correct form of the I-proposition, and thus A, B, D only fails to include all valid categorical types. It also still excludes nothing false beyond E, so it does not capture the full set of accurate statements.

Option D:
Option D is incorrect as it includes E along with B, C and D, thereby treating the false statement about I-propositions as if it were true. B, C, D, E only therefore mixes correct and incorrect information and cannot be accepted.

The pledge announced around COP28 calls for tripling global renewable energy capacity by 2030 compared to 2022 levels. It also aims to double the global average annual rate of energy-efficiency improvements. These twin goals are meant to accelerate decarbonisation of the power and end-use sectors while still supporting economic growth. They complement the broader Global Stocktake signals on transitioning away from fossil fuels.

Option A:
This option is correct because it states both parts of the pledge: a threefold increase in renewables and a doubling of efficiency gains. Together, they summarise the core quantitative ambition.

Option B:
This option is incorrect as it proposes reducing renewables and increasing fossil fuel subsidies, which runs counter to the spirit of the pledge.

Option C:
Tripling coal plants and weakening efficiency would increase emissions, not reduce them, so it contradicts the COP28 narrative.

Option D:
Focusing only on nuclear and ignoring renewables and efficiency does not match the text of the pledge. Nuclear may play a role, but it is not the sole focus.

Formative evaluation is used during the teaching learning process to gather information about students’ progress and the effectiveness of instruction. Its primary purpose is to provide feedback that can be used to modify teaching strategies and learning activities in real time. It is not usually used for certification or final grading. Therefore,the type of evaluation described in the stem is formative evaluation.

Option A:
Placement evaluation is done at the beginning of a course to decide the appropriate level or group for learners,and not primarily to improve ongoing instruction.

Option B:
Formative evaluation helps teachers identify misconceptions early and allows students to see where they need to improve before final assessments. Because the stem emphasises using evaluation to improve ongoing activities,formative is the correct choice.

Option C:
Summative evaluation occurs at the end of a unit or course and is mainly used for grading,categorisation or certification,rather than for continuous improvement during instruction.

Option D:
Diagnostic evaluation focuses on identifying specific learning difficulties and their causes,usually with more detailed tools; although it can inform improvement,its main purpose is specialised diagnosis,not continuous classroom feedback alone.

The 8-bit pattern 11111111₂ can be grouped into two nibbles: 1111₂ and 1111₂. Each nibble corresponds to the hex digit F (decimal 15). Combining them gives FF₁₆. Therefore, 11111111₂ maps to FF₁₆.

Option A:
Option A correctly uses nibble-to-hex mapping: 1111₂ = F, so 11111111₂ = FF₁₆.

Option B:
Option B, FE₁₆, would correspond to 11111110₂ and thus to decimal 254, one less than the maximum.

Option C:
Option C, F0₁₆, corresponds to 11110000₂, which is decimal 240 and not the full 8-bit maximum.

Option D:
Option D, 0F₁₆, corresponds to 00001111₂, a value much smaller than 11111111₂.

In this question statements A, B, D and E reflect core features of research design, while statement C is incorrect. Statement A is true because a research design indeed acts as a blueprint guiding data collection, measurement and analysis. Statement B is correct since a well-planned design seeks to minimise bias and enhance the reliability of data, and statement D properly characterises descriptive designs as portraying characteristics of populations or phenomena. Statement E is also true as causal-comparative research explores cause–effect relationships without direct manipulation of independent variables, whereas statement C is false because even exploratory studies require at least a tentative design or plan.

Option A:
Option A includes A, B and E but leaves out D. Although A, B and E are correct, D is also a true statement about descriptive research designs. By omitting D, this combination does not include all the correct statements and so cannot be accepted as the right answer.

Option B:
Option B selects B, D and E but omits A. While B, D and E are accurate, excluding A means the crucial general idea of research design as a blueprint for the entire study is missing. A complete set of correct statements must include A as well, so this option is incomplete.

Option C:
Option C correctly groups A, B, D and E, all of which present a coherent understanding of research design and related types of studies. It omits statement C, which wrongly suggests that exploratory studies do not need any design. Since this option contains all and only the true statements, it is the correct answer.

Option D:
Option D adds statement C to the otherwise correct combination of A, D and E. Because C is false, claiming that exploratory studies never require a design, its inclusion makes the entire combination incorrect. A valid option cannot mix misleading statements with true ones, so this choice is not acceptable.

HTTP defines the rules for communication between web browsers and web servers for requesting and delivering hypertext documents. The acronym officially expands to Hypertext Transfer Protocol, indicating its role in transferring hypertext resources. It is fundamental to web based ICT applications. Hence, the correct expansion is Hypertext Transfer Protocol.

Option A:
Option A is correct because standard networking references and exam syllabi identify HTTP as Hypertext Transfer Protocol. This phrase clearly mentions both hypertext and transfer, which are central to web interactions.

Option B:
Option B, Hyperlink Transmission Process, uses similar words but is not the recognised name and does not match official documentation.

Option C:
Option C, High Traffic Transport Protocol, suggests handling heavy traffic but has no standing as an internet standard acronym.

Option D:
Option D, Host Terminal Transfer Protocol, also sounds technical but is not the accepted expansion of HTTP in web technology.

Decomposing 156 yields 156 = 128 + 16 + 8 + 4, corresponding to bits in positions 7, 4, 3, and 2. Writing 1s in these positions and 0s elsewhere gives 10011100₂. Therefore, 10011100₂ is the binary form of 156.

Option A:
Option A accurately reflects the sum of powers of 2 equal to 156, using the positions for 2⁷, 2⁴, 2³, and 2². The resulting pattern converts back to 128 + 16 + 8 + 4, which is 156.

Option B:
Option B, 10011010₂, equals 128 + 16 + 8 + 2 = 154, which is slightly less than 156 and thus not correct.

Option C:
Option C, 10010110₂, represents 128 + 16 + 4 + 2 = 150, which is further from 156.

Option D:
Option D, 10011110₂, equals 128 + 16 + 8 + 4 + 2 = 158, overshooting the required value.
