UGC NET Questions (Paper – 1)

P-hacking refers to manipulating data analysis or selectively reporting results to obtain statistically significant p-values, often without a strong theoretical rationale. Researchers may try multiple models, subsets or transformations and only present analyses that produce significant findings. This practice inflates Type I error rates and undermines the credibility of research. Because the stem describes repeatedly analysing the same data until significance is found, p-hacking is the correct term.

Option A:
Stratification is a sampling technique that divides a population into homogeneous subgroups for more precise representation and is unrelated to manipulating analyses for significance. It is a legitimate methodological procedure rather than a questionable practice. Hence, stratification does not fit the stem.

Option B:
Triangulation involves using multiple methods, data sources or investigators to improve the credibility of findings and is generally considered a strength, not an unethical practice. It seeks converging evidence rather than repeated fishing for significance. Therefore, triangulation is not appropriate here.

Option C:
Pruning may refer to trimming decision trees or simplifying models in statistical or machine learning contexts, and is not commonly used to describe unethical searching for significant results. It also does not capture the selective reporting dimension implied in the stem. Thus, pruning is not the correct completion.

Option D:
P-hacking undermines the integrity of scientific literature because published significant findings may simply reflect exploratory searching rather than real effects. It highlights the need for transparent preregistration and replication. These concerns align with the scenario described in the question, confirming p-hacking as the accurate term.

Green buildings are designed to reduce resource use and environmental footprints throughout their life cycles. They incorporate strategies such as effective insulation, natural lighting, water-saving fixtures and sustainable materials. The goal is to provide comfortable, healthy indoor environments while using less energy, water and raw materials. Therefore, the feature emphasising efficient use of energy, water and materials with minimal environmental impact correctly reflects green building principles.

Option A:
Option A is correct because it summarises the integrated approach of sustainable building design. Such buildings often include renewable energy systems and rainwater harvesting, further lowering their ecological footprint.

Option B:
Option B is incorrect since exclusive reliance on air-conditioning and artificial lighting generally increases energy consumption. Green design encourages natural ventilation and daylighting wherever possible.

Option C:
Option C is incorrect because uninsulated concrete and glass buildings can lead to high heat gain or loss, making them energy inefficient. Green architecture promotes appropriate shading and insulation to maintain comfort with lower energy input.

Option D:
Option D is incorrect as ignoring local climate results in buildings poorly adapted to their environment. Climate-responsive design is a hallmark of sustainable architecture, reducing reliance on mechanical heating and cooling.

Decimal 255 is the largest number representable with eight bits set to 1, that is 11111111₂. Grouping the bits in fours gives 1111 and 1111, which correspond to F and F in hexadecimal. Thus, the hex representation of 255 is FF₁₆.

Option A:
Option A, EF₁₆, corresponds to 14×16 + 15 = 239, which is less than 255. It has a different high-order digit than FF.

Option B:
Option B, FE₁₆, represents 15×16 + 14 = 254, one less than 255. It is frequently seen in contexts like signed ranges, but it is not equal to 255.

Option C:
Option C is correct because FF₁₆ equals 15×16 + 15 = 255. It reflects a full set of ones in binary and is widely used as a maximum byte value.

Option D:
Option D, EE₁₆, equals 14×16 + 14 = 238, which is significantly smaller than 255. Its binary form does not have all bits set.

Teacher immediacy refers to verbal and non verbal behaviours that reduce psychological distance between teacher and students. Smiling,using names and moving closer all signal warmth and willingness to interact. These behaviours tend to increase student engagement and perceived approachability. Therefore,they are classic examples of teacher immediacy behaviours.

Option A:
This option is correct because immediacy behaviours encourage students to participate and feel connected to the teacher. Research shows that such behaviours are associated with higher motivation and satisfaction. The actions listed in the stem clearly demonstrate this closeness.

Option B:
Authoritarian behaviour emphasises strict control and distance,rather than friendly contact and approachability. Smiles and using names are inconsistent with a purely authoritarian style.

Option C:
Avoidance would involve withdrawing from students or reducing contact,which is the opposite of moving closer and engaging them.

Option D:
Mechanical behaviour would describe routine actions without emotional involvement,whereas immediacy behaviours convey personal warmth.

Sadhya is the intended probandum or target property that the argument seeks to demonstrate about the paksha. In the example, the aim is to show that the hill possesses fire, so "fiery" is the sadhya. All the inferential machinery of hetu, vyapti and example is mobilised to support this claim. Hence the property referred to in the stem is sadhya.

Option A:
Option A is correct because sadhya literally means "that which is to be established" and is used in Nyaya precisely for the attribute whose presence is concluded through inference. It marks the goal of the reasoning.

Option B:
Option B, paksha, is the subject "hill" in which the sadhya is to be proved and cannot itself be the property being predicated.

Option C:
Option C, hetu, denotes the reason "smoke" that supports the conclusion and thus has a different logical role from the probandum.

Option D:
Option D, drstanta, is the illustrative example employed to clarify the hetu–sadhya relation, usually a familiar case such as a kitchen where both smoke and fire co-occur.

Construct validity addresses whether test scores behave as expected based on theory about the underlying trait, such as intelligence or anxiety. Evidence for construct validity comes from patterns of correlations with other measures, factor analyses and studies of group differences. When findings fit theoretical predictions, confidence grows that the test indeed reflects the intended construct. Thus, the kind of validity in the stem is construct validity.

Option A:
Face validity concerns how appropriate a test appears on the surface and is judged informally; it does not provide deep evidence about theoretical interpretation of scores.

Option B:
Criterion validity examines the relationship between test scores and an external criterion measure, which is one aspect of construct validation but not the entire concept.

Option C:
Concurrent validity is a subtype of criterion validity focusing on correlations with criterion measures collected at the same time, not on the broader network of theoretical relationships.

Option D:
Construct validity integrates many pieces of evidence showing that scores relate to other variables in ways consistent with the theory of the construct. This focus on theoretical trait interpretation matches the stem, making this option correct.

A massive open online course is defined by its openness, large enrolment potential and online delivery. Learners can typically join from anywhere with internet access, often without strict entry requirements. Platforms such as SWAYAM, Coursera and edX popularise this model. Therefore the description in the stem clearly points to a MOOC.

Option A:
Option A, flipped classroom, refers to an instructional strategy where content delivery is moved outside class time and active learning occurs during contact hours. It may use online resources but is not inherently massive or open.

Option B:
Option B, modular open study plan, is not a standard technical term in ICT for education and does not capture the specific features of large-scale open online courses. It is a distractor phrase.

Option C:
Option C, blended learning cycle, suggests a mix of online and face-to-face components but does not indicate open access or very large enrolments. It is conceptually different from MOOCs.

Option D:
Option D is correct because "massive" refers to the large number of participants, "open" to flexible access and licensing, and "online course" to internet-based delivery, all of which are highlighted in the question.

Statements A and B correctly describe the multiplication and addition rules of counting, and D is true because many questions can be answered directly by reasoning about choices without naming permutations or combinations explicitly. Statement C is false since the multiplication rule in its simplest form assumes independence or appropriately defined conditional paths, and it cannot be applied blindly when choices are dependent. Statement E is false because counting principles are explicitly part of NET Unit 5. Thus, the combination A, B and D only is correct.

Option A:
Option A is correct as it includes the key rules and the note that problems can sometimes be solved without formal notation, while excluding C and E, which misrepresent the applicability of the multiplication rule and the syllabus.

Option B:
Option B is incomplete because it omits D, thereby failing to acknowledge that intuitive counting can sometimes bypass formal permutation or combination formulas in exam settings. Without D, the practical approach is not highlighted.

Option C:
Option C is wrong because it includes C, which incorrectly asserts that the multiplication rule applies regardless of dependence, and omits A, leaving out the fundamental statement of the rule itself.

Option D:
Option D is incorrect since it accepts C and thus endorses an overgeneralisation of the multiplication rule, even though A and D are true. The presence of C makes the overall combination logically unsound.

NEP 2020 emphasises that higher education should gradually expand offerings in Indian languages. Bilingual programmes are suggested to ease transition while maintaining international links. This can widen access for first-generation learners and strengthen local scholarship.

Option A:
Restricting to English medium alone is contrary to NEP’s multilingual vision.

Option B:
This option summarises the positive promotion of Indian languages in HEIs in the policy.

Option C:
Using only foreign languages would marginalise Indian languages even further.

Option D:
Prohibiting programmes in Indian languages directly contradicts the policy recommendations.

Statement C is wrong because statistical significance does not automatically imply practical importance; a small effect can be statistically significant in a large sample yet practically trivial. Statements A, B, D and E correctly describe the roles and potential misuses of statistics, including summarising data, the risk of misleading presentations, the need to report methods and the importance of understanding assumptions. Therefore, C alone is the incorrect statement in the list.

Option A:
Option A is correct because it isolates C as the sole misleading statement and acknowledges that the remaining statements align with good statistical practice. It emphasises the distinction between statistical and practical significance, which is crucial for sound interpretation.

Option B:
Option B is incorrect because it also labels A as wrong, even though A correctly explains that statistics help reveal patterns and relationships in data. Treating A as wrong underestimates the central purpose of statistical analysis.

Option C:
Option C is also wrong because it groups D with C, despite D rightly stressing transparency in reporting methods. Misclassifying D as wrong contradicts the principle of reproducible research.

Option D:
Option D is incorrect because it adds B and E to the set of wrong statements. Both B and E accurately warn about misleading presentations and the need to understand test assumptions, so including them with C misrepresents statistical best practices.

The positions of these letters are Z(26), W(23), T(20), Q(17) and N(14). The difference between consecutive terms is −3 each time (26→23, 23→20, 20→17, 17→14). Continuing the same rule, the next position is 14 − 3 = 11, which is the letter K. Therefore K is the unique letter that preserves the constant backward step of 3.

Option A:
Option A, L, is at position 12, which is only 2 steps behind N at 14. This contradicts the strict pattern of subtracting 3 from the position each time. Because L does not maintain the consistent decrement, it cannot be part of the series.

Option B:
Option B, M, corresponds to position 13, giving a difference of 1 from N. There is no indication that the size of the backward step is reducing as the series progresses. Since the pattern clearly shows a constant −3, M fails to fit the rule.

Option C:
Option C, J, is at position 10, which is 4 positions behind N. This would increase the backward jump to −4, altering the original rule of the sequence. As there is no evidence of changing step sizes, J does not correctly continue the series.

Option D:
Option D is correct because K is at position 11, exactly 3 positions before N. This maintains the uniform backward movement that characterises the sequence. Keeping the decrement constant is essential for logical consistency, so K is the only valid next term.

Inductive reasoning begins with particular examples or observations and uses them to infer a broader rule or generalisation. In mathematical aptitude, students often use inductive reasoning to guess a formula or pattern from a few terms of a sequence. The conclusions of induction are probable rather than certain because they rely on limited evidence. This fits the description of moving from specific cases to a general statement.

Option A:
Deductive reasoning starts from a general rule and applies it to specific cases, which is the opposite direction of what the question describes. For example, using a known formula to solve a numerical problem is deductive, not inductive. Therefore, although important in mathematics, it does not match the process of generalising from repeated observations. Hence, this option is not correct here.

Option B:
Inductive reasoning is correct because it explicitly captures the method of drawing a general rule from specific data or examples. When we look at several terms of a number pattern and propose a general formula, we are using induction. Many discoveries in mathematics and science begin with inductive reasoning before being rigorously proven deductively. Thus, this option perfectly matches the description given in the stem.

Option C:
Analogical reasoning compares one situation with another based on similarity and then transfers knowledge from the known case to the new one. It does not necessarily require repeated observations of many particular cases. Instead, it depends on perceived resemblance, which is different from forming a general rule from multiple examples. Hence, it is not the best answer to this question.

Option D:
Statistical reasoning involves using data, averages, and measures of dispersion to make inferences, often supported by probability. While it may also use samples, it is more focused on quantitative data analysis and formal methods. The question, however, asks about a general cognitive process of moving from specific to general, which is more precisely described by inductive reasoning than by statistical reasoning.

Hypertext Transfer Protocol (HTTP) is specifically designed for transmitting hypertext documents between web clients and servers. It defines how requests and responses are formatted and exchanged over TCP connections. When users browse websites, most of the communication occurs through HTTP or its secure version HTTPS. Thus, the protocol mentioned in the stem refers to HTTP.

Option A:
Option A, file transfer protocol, is used mainly for transferring files between hosts and is known as FTP, not for standard web page delivery.

Option B:
Option B, simple mail transfer protocol, abbreviated SMTP, is used for sending emails and does not handle browser-to-web-server hypertext transfers.

Option C:
Option C is correct because HTTP is explicitly spelled out as Hypertext Transfer Protocol in networking references and is the cornerstone of the World Wide Web.

Option D:
Option D, post office protocol, or POP, is used by email clients to retrieve messages from mail servers and is unrelated to web page transmission.

Unit planning involves designing a comprehensive plan for a block of content that extends across several class periods. It includes specifying objectives, selecting and sequencing content, choosing learning activities and planning assessment strategies. This broader view helps maintain coherence and continuity beyond a single lesson. Because the stem refers to a detailed outline for an entire topic over several lessons, it is describing unit planning.

Option A:
Unit planning ensures that each individual lesson contributes to clearly defined outcomes for the whole unit. Teachers can distribute activities, projects and assessments in a balanced way across time. Since the question emphasises preparation for an entire topic and not just one period, this option accurately names the process.

Option B:
Random teaching implies proceeding without systematic planning, choosing activities or content spontaneously without regard to long-term goals. Such an approach risks gaps and unnecessary repetition in the syllabus. It clearly contradicts the idea of a detailed outline mentioned in the stem.

Option C:
Spur-of-the-moment teaching refers to improvisation based on immediate ideas or circumstances, which may sometimes be useful but does not constitute structured planning. It lacks the comprehensive overview of objectives and evaluation for a whole topic. Therefore, it cannot be the correct description here.

Option D:
Ad hoc testing means giving occasional, perhaps poorly planned tests without integrating them into a larger assessment framework. It addresses only evaluation and not the full planning of objectives, content and activities for a unit. Thus, it does not match the broader planning described in the question.

Statements A, C and D correctly describe learner-centred strategies. A is true because such approaches emphasise students’ active involvement instead of passive reception. C is true since group work, projects and problem-solving tasks create opportunities for collaboration, inquiry and self-direction. D is true as learner-centred teaching demands attention to varied abilities, interests and learning styles. B is false because absolute teacher control and suppression of student choice contradict learner-centred principles, and E is false because, with careful planning, aspects of learner-centred teaching can be implemented even in large classes. Hence A, C and D only is the correct combination.

Option A:
Option A contains A, C and D and correctly excludes B and E. Therefore A, C and D only is the correct answer.

Option B:
Option B lists A and C but excludes D, which is also true. Thus A and C only is incomplete.

Option C:
Option C includes C and D but omits A, so it is incomplete.

Option D:
Option D includes B (false), so A, B, C and D only is not valid.

Option E includes E (false), so A, C, D and E only cannot be correct.
