UGC NET Questions (Paper – 1)

Eco taxes and subsidy reforms work by altering financial incentives so that environmentally harmful activities become more expensive and cleaner alternatives more attractive. These tools are classic examples of economic instruments. The stem explicitly refers to changing prices through taxes and subsidies,so “economic” instruments is the correct description. Option B is therefore right.

Option A:
Command and control instruments rely on regulations that set standards or limits and enforce compliance through penalties. They do not primarily operate by changing prices,so Option A is not suitable here.

Option B:
Economic instruments internalise environmental costs into market decisions by adjusting taxes,subsidies or tradable permits. This aligns exactly with the function described in the question.

Option C:
Informational instruments focus on providing data,labels or awareness to influence behaviour. While useful,they do not directly change price structures in the way eco taxes and subsidy removal do.

Option D:
Voluntary instruments involve self regulation or agreements without legal compulsion. They may accompany economic measures but are not defined by price changes,so Option D does not fit.

Statements A, B, D and E capture the main purposes of a review of related literature, while statement C is incorrect. Statement A is true because reviewing earlier studies helps to locate gaps in existing knowledge. Statement B is correct since understanding existing work helps the researcher refine the research problem and formulate or adjust hypotheses, and statement D is accurate because knowledge of prior studies prevents unnecessary duplication. Statement E is also true, as review of literature provides theoretical and conceptual frameworks for the study, whereas statement C is false because review is typically conducted before data collection, not only after it.

Option A:
Option A brings together A, B and D but omits E. Although A, B and D are true, excluding E means the important role of literature review in building theoretical and conceptual frameworks is not reflected. Since all four of A, B, D and E are correct, leaving one out makes this option incomplete and therefore incorrect.

Option B:
Option B correctly combines A, B, D and E, which together summarise the key functions of a literature review. It recognises that review helps to identify gaps, refine problems and hypotheses, avoid duplication and build conceptual frameworks. It also implicitly excludes statement C, which wrongly postpones literature review to only after data collection. Because it includes all and only the true statements, this option is the correct answer.

Option C:
Option C groups B, D and E but leaves out A. While B, D and E are true, A is also correct because identifying research gaps is a central reason for conducting a literature review. Omitting A leads to an incomplete specification of the review’s functions, so this option cannot be accepted.

Option D:
Option D includes A, D and E but also incorporates C, which is false. By suggesting that literature review is conducted only after data collection, statement C misrepresents standard research practice. Since this option mixes a false statement with true ones, it does not provide a valid set of correct statements.

Assumptions are implicit or explicit statements that the researcher accepts as true for the purposes of the study without directly verifying them within that study. Examples include assuming that instruments are understood correctly by respondents or that the sampling frame adequately represents the population. These assumptions underpin the design and interpretation of results. Because the stem refers to statements taken as true without direct testing that support the design, it is defining assumptions.

Option A:
Hypotheses are formal, testable statements about relationships between variables and are subjected to empirical verification during the study. They are not accepted as true in advance but are evaluated using data. Therefore, hypotheses do not match the idea of statements accepted without direct testing.

Option B:
Assumptions function as background conditions that need to be plausible for the design and conclusions to be valid. Researchers often state them explicitly so that readers can judge whether they are reasonable. This role aligns precisely with the stem’s description, confirming assumptions as the correct completion.

Option C:
Delimitations are boundaries that define the scope of the study, such as excluding certain populations or contexts. They are conscious choices rather than untested statements about reality. Hence, delimitations is not appropriate here.

Option D:
Recommendations are suggestions for action or further research offered at the end of a study based on its findings. They come after results are obtained and do not serve as pre-existing conditions on which the design rests. Consequently, recommendations cannot complete the stem correctly.

NEP 2020 defines the foundational stage as spanning ages 3–8. It includes three years of pre-school or Anganwadi-based ECCE plus Grades 1 and 2. This grouping reflects research on early brain development and the need for continuous play-based and activity-based learning. It is the base of the 5+3+3+4 structure.

Option A:
This option correctly connects the foundational stage to both ECCE and early primary grades, forming a coherent developmental block.

Option B:
Grade 12 alone is part of the secondary stage, not foundational.

Option C:
Ages 15–18 correspond to the senior secondary part of the secondary stage.

Option D:
Grades 6–8 form part of the middle stage, not foundational.

NEP 2020 stresses that teachers must be able to teach in the language children understand best, especially in the early years. Teacher education should therefore develop skills for rich, interactive teaching in mother tongue/local languages and also build competence in additional languages like English.

Option A:
Option A is incorrect because an English-only focus would undermine NEP’s strong recommendation for mother tongue-based education in early grades.

Option B:
Option B is correct as it reflects NEP’s integrated language vision: effective use of local languages plus capacity to teach additional languages.

Option C:
Option C is incorrect since ignoring language issues would leave teachers unprepared for multilingual classrooms and contradict NEP’s language policy.

Option D:
Option D is incorrect because training teachers merely to translate textbooks word-for-word does not meet the pedagogical goals of meaningful bilingual or multilingual teaching.

Statements A, B, C and E are correct because they reflect concerns about pollution havens, environmental clauses in trade rules, difficulties in tracing embedded impacts and the role of eco-labels in shaping markets. Statement D is false since there is no universal agreement that openness always improves environmental quality; outcomes depend on policies and structures. Statement F is false because environmental measures can sometimes be manipulated as disguised protectionism. Therefore, the combination A, B, C and E only is correct.

Option A:
Option A is incorrect as it omits E and so fails to consider the role of eco-labelling and certification in influencing consumer choices and firm behaviour.

Option B:
Option B is incorrect because it includes F, which incorrectly claims that environment-related trade measures can never be misused, despite evidence of such concerns in trade debates.

Option C:
Option C is correct since it combines structural, regulatory and market-based aspects of trade–environment linkages while rejecting overly optimistic or naive claims about openness and trade measures.

Option D:
Option D is incorrect as it includes D, which overstates consensus on the environmental benefits of trade openness, and excludes A, which describes a major environmental concern related to relocation of polluting industries.

Metacognition literally means “thinking about thinking” and includes awareness of one’s own cognitive processes. It involves knowing what strategies to use, when to use them and how well they are working during learning. Learners with strong metacognitive skills can plan, monitor and evaluate their understanding and performance. Therefore, the self-awareness and regulation of thinking described in the stem is called metacognition.

Option A:
Cognition refers broadly to mental processes such as perception, memory and reasoning. It describes thinking itself rather than awareness and control over that thinking. As such, it does not precisely capture the reflective, regulatory aspect highlighted in the question.

Option B:
Conditioning is a behaviourist concept describing how responses become associated with stimuli through reinforcement or punishment. It does not speak to learners’ conscious awareness or management of their cognitive strategies. Hence, it is not the appropriate term here.

Option C:
Metacognition encompasses both knowledge about one’s cognitive strengths and weaknesses and the self-regulatory actions taken during tasks. For example, a student may notice confusion and decide to reread or seek help. This kind of monitoring and adjustment is exactly what the stem points to, making this option correct.

Option D:
Reinforcement involves consequences that increase or decrease the likelihood of a behaviour reoccurring. It does not focus on a learner’s internal reflection on how they are thinking. Therefore, it cannot be equated with the concept of metacognition described in the stem.

Cloud computing provides scalable computing resources over networks without requiring users to manage physical servers. In education, this often appears as web based learning systems and storage services that can be reached from any connected device. The scenario described shows both applications and data residing on remote infrastructure. This is a clear example of academic cloud use.

Option A:
This option correctly reflects the on demand, network based access characteristic of cloud computing. It implies central management, easier collaboration and reduced local maintenance, which are key motivations for universities to adopt cloud services.

Option B:
Storing all data on a personal pen drive is a local and fragile solution. It lacks redundancy, collaboration features and remote accessibility that cloud services offer.

Option C:
Typewriters and filing cabinets represent purely manual processes and do not use shared virtual resources. They are the opposite of cloud based systems.

Option D:
Writing only on chalkboards creates no digital trail and cannot be accessed remotely. It does not exhibit any properties of cloud computing.

Statements A, B and D are correct, while C and E are incorrect. A is true because verbal communication covers both spoken and written use of language. B is true since clarity and conciseness directly affect how well a message is understood. D is true because prosodic features like tone and stress alter meaning. C is false as written forms are also verbal, and E is false because verbal and non-verbal cues often operate together. Therefore, the correct combination is A, B and D only.

Option A:
Option A presents A and B, which are both true, but it leaves out D, which is also a correct statement about how tone and emphasis shape meaning. Since one valid statement is missing, A and B only does not fully capture all the correct statements in the set and cannot be the best answer.

Option B:
Option B includes A, B and D, each of which correctly explains an aspect of verbal communication. It also excludes C and E, which wrongly restrict verbal communication to oral mode and deny its overlap with non-verbal cues. Because it gathers all and only the true statements, A, B and D only is the correct option.

Option C:
Option C combines B, D and E, but E is incorrect because verbal and non-verbal channels interact in real communication. Including E among supposedly correct statements makes this combination invalid, even though B and D are accurate. Hence, B, D and E only cannot be accepted.

Option D:
Option D groups A, D and E, but again E misrepresents the relationship between verbal and non-verbal communication. While A and D are accurate, adding E turns the set into a mix of true and false statements, so A, D and E only is not a correct answer.

Statements A, B and C correctly summarise three important digital initiatives, while statement D is incorrect. These platforms extend ICT-based resources to learners at different levels and often include teacher training modules as well. The claim that such initiatives always exclude teacher training does not match actual practice. Hence, the combination A, B and C only is the correct set of statements.

Option A:
Option A is correct because it includes all three true statements about SWAYAM, NPTEL and e-PG Pathshala, and excludes the false one. It recognises the scope of these initiatives in expanding ICT-enabled higher education. By rejecting D, it remains consistent with national policy directions.

Option B:
Option B is incorrect because it lists only A and B and omits C. Statement C is also true in describing e-PG Pathshala’s focus on postgraduate content. Any correct answer should include all three valid descriptions.

Option C:
Option C is incorrect because it groups B, C and D as correct, thus accepting D. Statement D wrongly suggests that teacher training is always excluded, which is contrary to many ICT-based faculty development efforts. Including D invalidates the combination.

Option D:
Option D is incorrect because it assumes all four statements are correct. Since D is incorrect, this set cannot be accepted as the correct answer.

Interactive teaching emphasises two-way communication and active participation by students. Teachers ask questions,encourage discussion and respond to learners’ ideas,creating a dialogue rather than a monologue. The stem specifically refers to frequent questioning and invitation of student ideas,which are hallmarks of interactive teaching.

Option A:
Interactive classrooms give students opportunities to clarify misunderstandings and construct knowledge collaboratively. Because the stem focuses on shared ideas and teacher questions,interactive is the correct term.

Option B:
Authoritarian teaching centralises control and allows limited student input,which contradicts the invitation to share ideas described.

Option C:
Didactic or monologic teaching is largely lecture-based,with the teacher doing most of the talking and few opportunities for student responses.

Option D:
Monologic emphasises one-way talk and is not consistent with frequent questioning and student contributions.

Negation in propositional logic is often represented by the symbol ¬ placed before a proposition. It expresses the logical opposite of the statement’s truth value: if the original proposition is true, its negation is false, and vice versa. This operator is fundamental in constructing complex statements and in defining other connectives using truth tables.

Option A:
Option A, ¬, is the standard modern symbol for “not,” used widely in logic texts and formal reasoning. It unambiguously marks the negation of whatever proposition follows it.

Option B:
Option B, ∧, denotes conjunction and is used for “and,” not for negation.

Option C:
Option C, ∨, is the symbol for disjunction, corresponding to “or,” and has a different truth function.

Option D:
Option D, ↔, stands for biconditional, “if and only if,” which expresses equivalence rather than negation.

Statements A, B, D and E describe sound practices in digital content curation, emphasising purposeful selection, organisation and contextualisation. Teachers must align resources with learning outcomes and student characteristics, and tags help manage collections. Statement C is false because copyright and licensing restrictions still apply to online materials. Statement F is also false since evaluating the credibility and authority of sources is central to responsible curation, so the correct set keeps only A, B, D and E.

Option A:
Option A is correct because it encapsulates the pedagogical and organisational aspects of curation without ignoring ethical and quality considerations. It properly omits the assumptions that everything online is free to use and that credibility checks are unnecessary. This reflects how teachers are expected to handle digital materials in formal education.

Option B:
Option B is incorrect because it includes C, implying that search-engine discovery automatically implies unrestricted reuse. This ignores copyright law and open licensing conditions, and therefore the presence of C makes the combination invalid.

Option C:
Option C is incorrect because it includes F, which downplays the need for evaluating sources. Even though A, D and E are true, accepting F contradicts basic information literacy principles. This mixture of correct and incorrect statements cannot be accepted.

Option D:
Option D is incorrect because it also includes F and omits A. Without A, the very definition of curation is not stated, and adding F suggests teachers need not worry about source reliability. Thus this option fails both conceptually and ethically.

Collaborative writing involves multiple contributors working together to produce a shared text, often negotiating content and revising each other's contributions. Online tools like shared documents and wikis make this process more visible and synchronous. Such practices align with constructivist views of knowledge construction. Hence, the joint editing described in the stem is collaborative writing.

Option A:
Option A, competitive, would emphasise individuals working against each other, which is the opposite of shared authorship.

Option B:
Option B is correct because the defining characteristic of collaborative writing is joint ownership and editing of the same document, which is enabled by the online tools mentioned.

Option C:
Option C, solitary, describes writing done by a single individual without input from others and does not fit the described activity.

Option D:
Option D, secretive, suggests hidden or confidential work rather than open co-editing among peers.

World Environment Day is a global platform for encouraging awareness and action for the protection of the environment. It is led by the United Nations Environment Programme and celebrated annually on 5th June. The day is used to highlight a specific environmental theme each year and mobilise governments, organisations and citizens. Thus, the correct date of observance is 5th June, making Option B the right answer.

Option A:
Option A is incorrect because 5th January has no special global status as World Environment Day. Confusing these dates can lead to mistakes in questions related to environmental events.

Option B:
Option B is correct as it identifies 5th June as the internationally recognised date for World Environment Day. This date has been associated with environmental campaigns and activities across the world since its establishment.

Option C:
Option C is incorrect; 15th August is celebrated as Independence Day in India, not as World Environment Day. It marks a political event rather than an environmental observance.

Option D:
Option D is incorrect; 10th December is observed as Human Rights Day by the United Nations. While important, it is not linked to the World Environment Day campaign.
