UGC NET Questions (Paper – 1)

The Choice Based Credit System is designed to provide flexibility in curriculum through electives, skill courses and the ability to move across disciplines. It allows students to accumulate credits over time and supports a learner-centred approach. The stem describes a system that supports choice, interdisciplinary courses and credit accumulation across semesters, which fits the Choice Based Credit System exactly. Thus, Option B is the correct answer.

Option A:
The Annual Examination Scheme refers to conduct of examinations once a year without emphasising course choice or credit accumulation. It is an older pattern that does not by itself guarantee flexibility or interdisciplinarity, so this option is incorrect.

Option B:
The Choice Based Credit System explicitly incorporates the idea of credits linked to learning outcomes and workload, which can be combined in multiple ways to form a programme. It supports flexible pathways and interdisciplinary exposure, aligning well with the question.

Option C:
A Fixed Credit Regime implies a more rigid structure with limited or no flexibility for learners to choose courses or adjust pacing. This is contrary to the concept being described in the stem, so it is incorrect.

Option D:
The Term-End Promotion Scheme is not a recognised framework in higher education for structuring curricula and credits. It does not address choice or credit-based flexibility, so this option does not answer the stem appropriately.

The differences in the series are 3, 5, 7 and 9, which form an increasing sequence of odd numbers. To continue this pattern, the next difference should be 11. Adding 11 to the last term 26 gives 26 + 11 = 37. This maintains the smooth growth of the differences and fits well with the structure of the given series. Therefore, 37 is the only option that preserves the observed pattern.

Option A:
Option A provides 37, which is obtained by adding the next odd difference 11 to 26. The difference sequence 3, 5, 7, 9, 11 remains perfectly consistent and shows a clear second level arithmetic pattern. This makes 37 the logically correct continuation of the number series.

Option B:
Option B gives 35, which corresponds to adding 9 to 26 and simply repeating the last difference instead of increasing it. This breaks the rule that differences themselves should grow by 2 each time. Hence, 35 does not correctly follow the pattern governing the series.

Option C:
Option C gives 38, which would require a difference of 12 from 26, overshooting the next expected odd difference of 11. This disrupts the systematic progression of differences and introduces an unjustified jump. Therefore, 38 is not a valid extension of the series.

Option D:
Option D suggests 40, which would create a difference of 14 from 26 and move even further away from the orderly sequence of odd differences. Such a large change is inconsistent with the established pattern of gradually increasing differences. Thus, 40 cannot be accepted as the next term.

Statements A, B and D are correct descriptions of web browsers, whereas statement C is misleading. Browsers are application software for accessing web content, bookmarks save favourite URLs and extensions add extra features such as ad blocking or note-taking. Private or incognito mode mainly limits local storage of history and cookies on the device, but does not prevent all tracking by websites or network providers. Hence the correct combination is A, B and D only.

Option A:
Option A is incorrect because it lists only A and B as correct, omitting D. Although accessing web resources and bookmarking are important functions, extensions and add-ons are also widely used to extend browser capabilities. Leaving out D makes the description incomplete.

Option B:
Option B is incorrect because it treats all four statements as correct and therefore accepts C. Since C overstates the protection offered by private mode, including it results in a factually inaccurate combination.

Option C:
Option C is incorrect because it includes only B and D and omits A. A defines what a web browser is, so excluding it weakens the conceptual understanding of the tool. Additionally, this option does not address the inaccuracy in statement C.

Option D:
Option D is correct because it acknowledges basic browser functions and the role of extensions while rejecting the exaggerated privacy claim in C. It presents a realistic view of what private browsing can and cannot do.

Information overload occurs when the volume of available material exceeds a person’s capacity to process it meaningfully. The solution is not to consume more indiscriminately, but to become selective and strategic. Information literacy combines skills in formulating precise questions, choosing appropriate databases, using filters and evaluating authorship, evidence and bias. Learners who master these skills can turn abundance into an asset rather than a burden.

Option A:
Treating all sources as equally valid undermines academic quality and can lead to the use of misinformation. Scholars are expected to differentiate between peer-reviewed research, opinion pieces and unverified claims.

Option B:
This option correctly emphasises a proactive, skills-based approach to managing digital information. By learning how to search and evaluate systematically, students can focus on the most relevant and trustworthy resources, saving time and improving the quality of their work.

Option C:
Completely avoiding digital resources would cut learners off from up-to-date research and many primary documents. It is neither realistic nor desirable in contemporary higher education.

Option D:
Copy-paste behaviour without reading constitutes poor scholarship and often leads to plagiarism. It does not contribute to understanding and ignores the need for synthesis and critical thinking.

Statements A, B and C accurately describe key affordances of digital note-taking tools, while D is false. Many applications sync across devices, accept stylus-based handwriting and support tags and search to manage large volumes of notes. Collaboration and sharing features are increasingly common, so it is incorrect to say that such tools necessarily block collaboration. Therefore, the only fully correct set of statements is A, B and C.

Option A:
Option A is correct because it brings together the main learning-related strengths of digital note-taking without including the restrictive and incorrect claim in D. It highlights portability, input flexibility and retrieval efficiency, which are all valuable for students.

Option B:
Option B is incomplete because it includes only A and B and omits C. Without mentioning tags and search, the description underestimates how these tools support efficient retrieval and organisation of information.

Option C:
Option C is incomplete because it lists only B and C and leaves out A. Statement A about cross-device storage and organisation is fundamental to the appeal of such tools in ubiquitous learning contexts.

Option D:
Option D is incorrect because it treats all four statements as correct and thereby accepts D. Since many note-taking tools explicitly offer sharing and collaborative editing, claiming that collaboration is impossible is wrong.

200 = 128 + 64 + 8, so bits for 2⁷, 2⁶, and 2³ are 1, giving 11001000₂.

Option A:
Option A matches 128 + 64 + 8 = 200.

Option B:
Option B equals 196 (128 + 64 + 4).

Option C:
Option C equals 212 (128 + 64 + 16 + 4).

Option D:
Option D equals 168 (128 + 32 + 8).

Virtual labs use computer-based simulations and remote access technologies to allow students to perform experiments online. They are particularly useful when physical access to laboratories is limited or when experiments are expensive or hazardous. The stem describes online platforms that simulate experiments, which are correctly called virtual labs, making Option C the appropriate answer.

Option A:
Virtual labs can supplement hands-on work by allowing repeated practice and exploration of scenarios that are difficult to replicate physically. They illustrate the increasing role of ICT in the higher education system, especially in science and engineering disciplines. These features align closely with the scenario outlined in the question.

Option B:
Real-time physical labs refer to experiments conducted in an actual laboratory space with equipment, which is different from online simulations. Option A thus does not match the description of experiments done virtually.

Option C:
Open book refers to a type of examination where students can consult materials, not to laboratories or experimental platforms. Option B is therefore unrelated to the stem.

Option D:
Manual-only labs would suggest exclusively physical, hands-on work without digital tools, which is precisely the opposite of virtual labs. Hence, Option D is not correct.

In mathematical induction, there are two main parts: the base case and the inductive step. The inductive step assumes that the statement holds for n = k (the induction hypothesis) and then proves that it must also hold for n = k + 1. This step is called the inductive step because it extends the truth from one case to the next. Hence, the description in the question refers to the inductive step.

Option A:
The basis or base step is where we verify that the statement holds for the initial value, usually n = 1 or n = 0. It does not involve the assumption "if true for k then true for k + 1." Therefore, basis does not match the part described in the question.

Option B:
Verification is a general term that could refer to checking any part of the proof. It is not the standard technical name for the specific step that connects n = k to n = k + 1. Hence, it is too vague and not suitable as an answer.

Option C:
The inductive step is correct because it formalises the logical link needed to propagate the truth of the statement from one natural number to the next. Once both the base case and inductive step are established, the statement is proved for all natural numbers in the domain. Recognising this terminology is important for understanding proofs in discrete mathematics and reasoning.

Option D:
Concluding step might describe the final remarks of a proof, but it is not a standard name for the process of moving from k to k + 1. The main logical engine in induction is the inductive step, not a generic conclusion. Thus, this option is not accurate.

The terms follow the rule aₙ = n⁴ + 5n with n starting from 1. Substituting n = 1, 2, 3, 4 and 5 gives 6, 26, 96, 276 and 650, exactly the given sequence. Applying the same expression for n = 6 produces 1326. Therefore 1326 is the unique value that continues this polynomial pattern without any change in the rule.

Option A:
Option A gives 1326, which is precisely the value obtained from aₙ = n⁴ + 5n when n = 6. It preserves the same functional relationship between n and aₙ that generates all earlier terms. Hence this option correctly represents the next term of the series.

Option B:
Option B proposes 1314, which is close but does not equal the value from n⁴ + 5n at n = 6. To obtain 1314 we would need to subtract 12 from the polynomial result only at this step. Since no such irregular adjustment appears in the previous terms, 1314 cannot be the correct continuation.

Option C:
Option C suggests 1338 as the next term. This number is 12 greater than the value predicted by the rule for n = 6. Introducing such an extra increment only at the sixth term would break the consistent algebraic pattern, so 1338 is not acceptable.

Option D:
Option D gives 1350, which deviates even further from the calculated value 1326. No single formula of the form n⁴ + 5n can generate the first five terms and then jump to 1350 next. Because it would require altering the rule at the last term, this option is incorrect.

Synchronous communication occurs when participants interact at the same time,allowing immediate feedback. Video conferencing classes enable teachers and students to see and talk to each other simultaneously,even from different locations. This fits the definition of synchronous communication.

Option A:
Asynchronous communication,like email,does not require participants to be online at the same time.

Option B:
Synchronous interaction supports two way questioning and clarification in real time,making this option correct.

Option C:
One way communication would not allow immediate responses.

Option D:
Intrapersonal communication happens within one person and is not mediated by online platforms.

Statements A, B and C are correct, while D is incorrect. A is true because the cognitive component emphasises how learners think about and make sense of information. B is true since affective aspects such as interest, anxiety and attitude shape how messages are received. C is true because psychomotor elements relate to physical performance of tasks based on communicated instructions. D is false because effective teaching should integrate cognitive, affective and psychomotor dimensions rather than focusing on cognition alone.

Option A:
Option A presents A and B only and omits C, thereby ignoring the role of psychomotor action in classroom tasks such as experiments or demonstrations. As C is also a correct statement, A and B only does not represent the full set of correct components. Hence this option is incomplete.

Option B:
Option B combines B and C but leaves out A, failing to acknowledge the central role of understanding and processing information in classroom communication. While B and C are correct, excluding A makes the description of components partial. Therefore B and C only cannot be the correct answer.

Option C:
Option C includes A, B and C, accurately summarising cognitive, affective and psychomotor components and rejecting the narrow view in D. By bringing together all the true statements and excluding the false one, A, B and C only is the correct option.

Option D:
Option D treats all four statements as correct, but D wrongly claims that effective communication can ignore affective and psychomotor aspects. Since D contradicts holistic views of learning, including it invalidates the combination. Thus this option is not acceptable.

The Domain Name System is a distributed database that maps domain names to IP addresses. When users type a domain name, DNS servers resolve it to the corresponding numerical address so that communication can occur. This makes the internet more user friendly by hiding complex numbers behind simple names. Thus, the service described is the Domain Name System.

Option A:
Option A is correct because Domain Name System is the officially recognised expansion of DNS and matches the function of name resolution.

Option B:
Option B, Dynamic Network Service, is not the standard term and does not appear in networking standards as the meaning of DNS.

Option C:
Option C, Digital Number Server, is an invented phrase and does not accurately describe the established internet naming infrastructure.

Option D:
Option D, Domain Navigation Service, may sound related but is not the accepted name for the protocol and system performing this task.

Statements A, B and D are correct, while C is the only wrong statement. A is correct because ethical feedback must be honest but also respectful in language and tone. B is correct as publicly shaming or negative comparisons can damage students’ dignity and should be avoided. D is correct because sarcastic remarks that belittle students undermine trust and should not be used in feedback. C is wrong since confidential aspects of performance should not be discussed openly in public spaces; doing so violates privacy.

Option A:
Option A is incorrect because it groups A and C as wrong statements. A is in fact a correct ethical guideline emphasising honesty combined with respect. Although C is wrong, the inclusion of A makes this option an inaccurate representation of the wrong statements.

Option B:
Option B is incorrect because it lists B and C as wrong, even though B correctly highlights the harm caused by public negative comparisons. By treating B as wrong, the option misrepresents accepted ethical standards in assessment communication. Therefore B and C only cannot be chosen.

Option C:
Option C is incorrect because it pairs C and D as wrong statements. While C is wrong, D is correct in warning against sarcastic remarks that ridicule students’ efforts. Including D among wrong statements makes this combination logically inconsistent.

Option D:
Option D is correct because it singles out C only as the wrong statement. C wrongly suggests that confidential aspects of student performance may be openly discussed, which violates privacy and ethical norms. By keeping A, B and D outside the wrong set as correct principles, this option aligns with ethical communication practices.

A viruddha hetu is one whose accepted vyāpti actually leads to a conclusion contrary to what the reasoner wants to prove. Instead of supporting the intended sādhya, the middle term supports its negation. This makes the inference self defeating, because if the hetu is accepted, the conclusion must be the opposite of the stated thesis. Such a reason is deeply defective, as it undermines the very claim it is meant to justify.

Option A:
Option A characterises an asiddha hetu, where the middle term is not established in the pakṣa; this is a different kind of fallacy.

Option B:
Option B mentions over narrowness but does not capture the central feature of viruddha, namely reversing the intended conclusion.

Option C:
Option C correctly identifies that a viruddha hetu proves the contrary of the thesis on the basis of its own vyāpti, making the argument logically self destructive.

Option D:
Option D focuses only on the source of evidence; dependence on scripture is not, by itself, what defines viruddha in technical classifications of hetvābhāsa.

Statements A, B, C and E provide a correct understanding of triangulation and mixed-methods research, whereas statement D is wrong. Statement A is true because triangulation involves using multiple methods, sources, investigators or theories to study the same phenomenon. Statement B is correct as triangulation is often used to enhance credibility and validity by cross-checking findings, and statement C accurately defines mixed-methods research as combining qualitative and quantitative approaches. Statement E is also true because mixed-methods designs may implement qualitative and quantitative phases either sequentially or concurrently, while statement D is false since triangulation is not restricted to quantitative experiments and is widely used in qualitative and mixed-methods studies as well.

Option A:
Option A groups A, B and C, all of which are correct, but leaves out E. By omitting E, it does not fully reflect how mixed-methods studies can organise qualitative and quantitative phases over time. Since E is also a true statement, this combination is incomplete and cannot be the correct answer.

Option B:
Option B includes B, C and E but omits A. Although B, C and E are true, leaving out A ignores the general definitional statement that triangulation uses multiple methods, sources or investigators. Because the complete set of correct statements must contain A as well, this option is inadequate.

Option C:
Option C correctly lists A, B, C and E and excludes D, which is false. It captures the meaning and purpose of triangulation, the nature of mixed-methods research and the possible sequencing of qualitative and quantitative components. Since it contains all and only the true statements, this option is the best answer.

Option D:
Option D combines A, C, D and E and thereby includes D, which incorrectly restricts triangulation to quantitative experimental designs. Triangulation is widely used outside experimental settings, particularly in qualitative and mixed-methods studies. The inclusion of a false statement invalidates this combination.
