UGC NET Questions (Paper – 1)

The campaign aims to make durable cloth bags easily accessible and affordable so that people do not rely on disposable plastic bags. By installing vending machines at public places, it reduces convenience barriers and normalises carrying reusable bags. This supports state and national efforts to curb single-use plastics and fosters a culture of reuse and waste prevention.

Option A:
This option correctly reflects the core objective of the initiative, which is to change everyday consumer behaviour away from plastic carry bags.

Option B:
This option is incorrect; the programme is explicitly against unnecessary plastic purchases.

Option C:
The campaign does not oppose waste segregation; reducing single-use plastics complements better waste management.

Option D:
While tourists may also use the bags, the initiative is primarily about habitual local shopping behaviour, not souvenirs.

Yogaja pratyaksha is a special kind of perception said to arise from yogic concentration and discipline, allowing direct awareness of subtle realities that ordinary senses cannot reach. It is considered alaukika because it does not depend on usual sense-object contact. Traditional texts describe yogaja perception as immediate and self-evident to the yogi. Therefore the supernormal awareness mentioned in the stem is called yogaja pratyaksha.

Option A:
Option A, laukika, refers to everyday empirical perception through external senses and cannot account for the extraordinary, meditative origin of yogic awareness.

Option B:
Option B, samanyalaksana, is focused on perceiving universals through their instances, not on supernormal access to hidden or distant objects.

Option C:
Option C is correct because yogaja directly points to yogic origin, distinguishing these cognitions from both ordinary perception and reasoning. It preserves the claimed immediacy of such insights while acknowledging their exceptional status.

Option D:
Option D, anumana, is mediate inferential knowledge and lacks the immediacy and non-discursive character attributed to yogic perception.

In digital systems, all information is represented using bits that can take values 0 or 1. Eight such bits are grouped to form a byte, which becomes the standard unit for measuring memory and storage. This convention allows consistent encoding of characters and small data items across devices, so describing a byte as a group of 8 bits is correct.

Option A:
This option correctly states that eight bits together form one byte, matching standard computer architecture. It highlights that the byte is a fundamental unit for measuring memory and storage capacity.

Option B:
This option reverses the relationship by claiming that a bit is made of 8 bytes, which is conceptually wrong. A bit is the smallest unit, whereas a byte is formed from bits. It also incorrectly suggests that bits directly store characters, ignoring that encodings typically use bytes.

Option C:
This option wrongly claims that a bit and a byte always represent the same quantity of data. A byte clearly represents more information than a single bit because it has eight binary positions.

Option D:
This option associates bytes only with analog communication, which is incorrect because bytes are central to digital computing and networking. Analog systems do not use bytes in the same structured way as digital systems.

NEP 2020 identifies the four-year integrated B.Ed. as the standard preparation route for school teachers. It combines content studies with professional courses and practicum. The programme is to be offered in multidisciplinary universities and colleges. This model replaces fragmented and shorter programmes over time.

Option A:
A one-year programme is considered too short for comprehensive teacher preparation in the NEP framework.

Option B:
Two-year B.Ed. programmes will exist only as a transitional arrangement and not as the long-term main route.

Option C:
Three-year models are not emphasised in the policy; the key emphasis is on a robust four-year integrated course.

Option D:
Four years provide enough time to integrate disciplinary knowledge, pedagogy and practicum, which is why NEP recommends this duration.

Pūrvavat anumāna reasons from a presently observed cause to a future effect, based on previous experience of that sequence. Seeing dark, rising clouds and inferring that rain will soon occur is the stock illustration: clouds are known to precede rainfall. The temporal direction is from what comes earlier (cause) to what comes later (effect).

Option A:
Option A, inferring fire from smoke already on a hill, is typically treated as śeṣavat or anvayavyatireki, since smoke is regarded as the effect of an already present fire, not as a cause of future fire.

Option B:
Option B, inferring past rain from a swollen river, moves from a present effect to a past cause and is a standard example of śeṣavat anumāna.

Option C:
Option C correctly shows a present cause (dark clouds) used to infer a future effect (rain), which is the defining pattern of pūrvavat.

Option D:
Option D, inferring air from the movement of leaves, is an example of sāmānyatodṛṣṭa anumāna, where a generally observed association (moving leaves with air) is used to infer an unseen entity, not specifically a cause–future-effect sequence.

The ecological footprint aggregates how much biologically productive area is needed to provide the resources a population consumes and to assimilate its wastes, especially CO₂. It is usually expressed in global hectares and compared with available biocapacity. When the footprint exceeds biocapacity, it indicates ecological overshoot. Thus, the concept focuses on human demand for nature’s services translated into area terms.

Option A:
Option A is incorrect since a country’s physical area does not by itself show how intensively resources are used or how much is imported from elsewhere.

Option B:
Option B is correct because it explicitly links consumption and waste to the amount of productive land and water needed, which is the core idea behind the footprint indicator.

Option C:
Option C is incorrect because total population size does not automatically indicate environmental pressure; lifestyles and technologies matter.

Option D:
Option D is incorrect since species richness describes biodiversity, not human demand on ecosystems.

Asynchronous communication does not require participants to be online simultaneously. Discussion forums allow learners to read and write posts when convenient, supporting reflection and flexible access. Teachers can respond later, and threads remain available for revision. Therefore, this example clearly represents asynchronous interaction supported by ICT.

Option A:
This option correctly shows time independence as the defining feature of asynchronous modes. It illustrates how ICT extends classroom dialogue beyond fixed schedules and allows participation from diverse locations and time zones.

Option B:
Live lectures require everyone to connect at the same time, which is characteristic of synchronous communication. Audio and video flow in real time, so this example is not asynchronous.

Option C:
Scheduled webinars with real-time chat are also synchronous, as the event happens at a specific time and participants interact instantly.

Option D:
Online viva voce examinations involve immediate questioning and answering, which is again synchronous.

Statements A, B, C and E highlight key strengths and safeguards of using databases for educational administration. RDBMSs store structured records, normalisation reduces redundancy, role-based access protects confidentiality and backups with logs enable recovery. Statement D is wrong because spreadsheets are not inherently superior and can become unmanageable at scale. Statement F is also false since validation rules are specifically designed to reduce common entry errors, so the correct set excludes D and F while keeping A, B, C and E.

Option A:
Option A is incorrect because it omits E, thereby failing to recognise the importance of backup and recovery mechanisms in protecting institutional data. Even though A, B and C are true, they do not cover resilience against failures, so the combination is incomplete.

Option B:
Option B is incorrect because it includes D, which asserts that spreadsheets are always superior to database systems. Large-scale educational data management usually benefits from database features such as concurrency control and queries, so including D introduces a clear misconception.

Option C:
Option C is correct because it captures the main design and maintenance principles relevant to educational databases. It acknowledges structure, consistency, access control and recovery while rejecting simplistic claims about spreadsheets and the irrelevance of validation. This makes it the best answer.

Option D:
Option D is incorrect because it includes F while omitting A. Accepting F suggests that validation is unnecessary, which contradicts good database design practice. Leaving out A also removes the basic point about what RDBMSs store, so this option cannot be accepted.

Statements A, B and D correctly indicate the value of NSS and NCC. A is true because NSS involves students in community-oriented work and social campaigns. B is true as NCC builds discipline, leadership and civic responsibility through drill, camps and training. D is true since certificates, credits and awards for participation can motivate more students to join. Statement C is false; these activities significantly contribute to holistic development by fostering social sensitivity and leadership traits. Therefore, A, B and D only are correct.

Option A:
Option A is incorrect because it includes A and B but omits D, overlooking the motivational role of institutional recognition in expanding participation.

Option B:
Option B is incorrect because it includes A and D but leaves out B, thus not explicitly acknowledging NCC’s contribution to discipline and leadership, which is a core part of its mandate.

Option C:
Option C is incorrect because it selects B and D only and omits A, failing to mention the community service and social development aspects that NSS emphasises.

Option D:
Option D is correct because it combines A, B and D, capturing community service, leadership development and recognition, while excluding C, which wrongly denies the developmental benefits of these programmes.

The Intergovernmental Negotiating Committee was created to turn the UNEA resolution on plastic pollution into a concrete treaty text. It brings together representatives of UN member states to discuss options, draft provisions and resolve disagreements. Through successive INC sessions in different cities, negotiators work on issues such as production limits, chemicals, waste management and financial mechanisms. Thus, the INC is the central negotiating body rather than an implementing agency or tribunal. (UNEP - UN Environment Programme)

Option A:
This option is incorrect because recycling programmes are largely managed at national or local levels; the INC does not administer them. Its mandate is to negotiate treaty text, not to run operational projects within countries.

Option B:
The INC does not function as a funding agency that dispenses money directly to waste management projects. Finance will be an important part of the treaty, but such mechanisms are to be designed within the negotiations rather than administered by the INC itself.

Option C:
This option correctly describes the INC’s purpose as a negotiating forum charged with drafting the new plastics treaty. It reflects the intergovernmental nature of the process and the focus on legal text and obligations. Without such a body, the UNEA resolution could not be translated into a concrete, binding instrument.

Option D:
The INC is not a court or enforcement body that directly punishes companies. Any compliance or enforcement provisions would be part of the treaty architecture and would typically involve states, not direct corporate adjudication by the committee.

Statements A, B, D, E and F cover essential aspects of research data management, while C contradicts good practice. Plans outline processes for collection, storage and sharing, consistent naming improves organisation and access controls protect sensitive data. Metadata and retention rules support reuse and compliance. Avoiding backups purely to save storage is unsafe, so C must be excluded, leaving A, B, D, E and F as the correct set.

Option A:
Option A is correct because it gathers all the statements that align with recognised research data management principles. It addresses planning, organisation, security, documentation and retention obligations. By rejecting C, it also signals that backups are indispensable despite storage costs.

Option B:
Option B is incorrect because it omits F, thereby ignoring legal and ethical considerations in retention periods. Although A, B, D and E are true, leaving out F makes the picture of data management incomplete.

Option C:
Option C is incorrect because it excludes A, which defines what a research data management plan does. B, D, E and F are true, but without A, the role of a formal plan is not acknowledged.

Option D:
Option D is incorrect because it omits B, removing the idea of consistent naming conventions. A, D, E and F are correct, yet overlooking organisation practices makes the answer incomplete.

The BCC feature allows the sender to include additional recipients without revealing their email addresses to others in the message. This helps maintain privacy, especially when emailing large groups or external stakeholders. It is useful in academic contexts where confidentiality or discretion is required. Hence, the key purpose of BCC is to send hidden copies, as stated in this option.

Option A:
This option correctly explains that BCC hides recipient addresses from other addressees. The recipients in the BCC field still receive the message, but their identities remain invisible in the email header. This supports responsible mailing practices and reduces the risk of exposing private contact information. Therefore, it is the accurate description of BCC usage.

Option B:
File attachments, including documents and multimedia, can be added regardless of whether BCC is used. The presence of attachments is controlled by separate functions in the email client. Hence, this option confuses two different features.

Option C:
Automatic translation is an advanced feature provided by some email clients or external tools. It is not tied to the BCC field, which is purely about recipient visibility. Therefore, linking BCC to translation shows a misunderstanding of email components.

Option D:
Marking an email as spam is typically done by the receiver’s email system or manually by the user. The BCC field has nothing to do with labelling messages as spam or preventing delivery to others. Thus, this option is incorrect.

Statements A, B, C and D are correct, whereas E is incorrect. A is true because downward communication typically carries directives and policy information. B is true since upward channels allow employees to send feedback and complaints. C is true as horizontal communication links units at the same level. D is true because diagonal communication cuts across both departmental and hierarchical boundaries. E is false because effective organisations rely on multi-directional communication, not just downward flow. Thus, A, B, C and D only is the correct combination.

Option A:
Option A lists A and B only and overlooks C and D, ignoring the roles of horizontal and diagonal communication in coordination across the organisation. As the question explicitly refers to different directions, A and B only is incomplete.

Option B:
Option B adds C to A and B, but still omits D, failing to mention diagonal flows that connect different levels and departments. Consequently, A, B and C only does not represent the full set of correct statements.

Option C:
Option C assembles A, B, C and D, correctly summarising downward, upward, horizontal and diagonal communication, and excludes E, which wrongly privileges only downward communication. Because it includes all and only true statements, this option is correct.

Option D:
Option D groups B, C and E, but E is incorrect as it denies the necessity of multi-directional communication for effectiveness. Including E in a “correct” set makes B, C and E only invalid.

The leftmost bit in a binary number carries the largest positional weight because it corresponds to the highest power of 2 in the representation. This makes it the most significant bit (MSB). Its value greatly influences the magnitude of the entire number. Therefore, it is correctly referred to as the most significant bit.

Option A:
Option A labels it "low order," which is usually associated with bits near the right side that carry smaller weights. Using low-order terminology for the leftmost bit contradicts standard conventions in digital design.

Option B:
Option B suggests a parity bit, which is a special bit added to detect errors. A parity bit may be placed at either end of a word and is not inherently the leftmost data bit. Thus, parity does not define the leftmost bit of any binary number.

Option C:
Option C is correct because the leftmost bit has the greatest influence on the numeric value and is therefore called the most significant. In signed representations, this bit may also indicate the sign of the number, reinforcing its significance.

Option D:
Option D uses the term "overflow" bit, which typically refers to a flag indicating arithmetic overflow in a status register. It is not a positional name for any particular bit within a numeric representation.

Contraposition is an operation that takes a conditional or certain categorical propositions and transforms them by swapping subject and predicate while also negating each. For example, “If p, then q” becomes “If not q, then not p”, and these are logically equivalent. This method is often used in proofs because the contrapositive of a true conditional must also be true. Thus the inference described in the stem is contraposition.

Option A:
Option A, conversion, simply interchanges subject and predicate without negating them, as when “No S are P” is converted to “No P are S”. It does not include the additional step of negation that characterises contraposition.

Option B:
Option B, obversion, changes the quality of a proposition and replaces the predicate with its complement but does not interchange subject and predicate. It is a different immediate inference.

Option C:
Option C is correct because contraposition uniquely combines reversal of order with negation of both terms, yielding a statement equivalent to the original under classical logic for suitable forms. This fits the description given in the question.

Option D:
Option D, equipollence, is sometimes used to describe equivalence obtained by combining operations like obversion and conversion, but it is not the standard name for the specific transformation outlined in the stem.
