UGC NET Questions (Paper – 1)

Statements A, B and D are correct, whereas C is incorrect. A is true because technical issues such as poor sound and lag interfere with the transmission of messages. B is true since excessive on-screen stimuli can overload learners’ processing capacity, functioning as psychological noise. D is true as using a clear layout, limited text and simple visuals helps minimise competing signals. C is false because noise includes any interference, not just physical sound, and covers distractions, overload and technical disruptions.

Option A:
Option A lists A and B only and omits D, overlooking the role of thoughtful slide and interface design in reducing noise. Because D is also a correct statement, A and B only underrepresents strategies for dealing with online noise. Hence this option cannot be accepted.

Option B:
Option B combines A and D but leaves out B, ignoring the cognitive dimension of noise produced by overloaded screens. Excluding B means the option does not fully explain how noise can arise in online contexts. Therefore A and D only is not the correct answer.

Option C:
Option C correctly groups A, B and D and excludes C, which wrongly restricts noise to literal sound. It recognises technical, cognitive and design aspects of noise in online education. For this reason, A, B and D only is the right choice.

Option D:
Option D includes B, C and D, but C contradicts the broader conception of noise used in communication theory. Including C with accurate statements makes the combination internally inconsistent. Consequently, B, C and D only cannot be chosen.

Statements A, B, C, E and F summarise sound practices for participating in educational video conferences, while D is unnecessarily restrictive. Muting, making connectivity stable, protecting meeting links, using headsets and checking video setup all support clear and secure communication. Chat features are often encouraged for questions, especially in large webinars where voice interruptions can be disruptive. Therefore D is not correct, and the set of true statements is A, B, C, E and F.

Option A:
Option A is incorrect because it omits F, which highlights the importance of camera framing and lighting. While A, B, C and E are true, ignoring visual presentation overlooks a key aspect of professional online presence. Hence this combination does not include all correct statements.

Option B:
Option B is incorrect because it excludes C, thereby failing to acknowledge risks of posting meeting links publicly. Without C, the combination does not address security threats such as unwanted intrusions into educational sessions. As a result, it is incomplete.

Option C:
Option C is correct because it includes A, B, C, E and F, all of which promote effective and secure participation. It explicitly excludes D, which wrongly discourages the constructive use of chat for questions. This makes Option C the only set that aligns with recommended etiquette for educational video conferencing.

Option D:
Option D is incorrect because it leaves out A, which recommends muting microphones when not speaking. Although B, C, E and F are true, omitting A neglects a basic practice for maintaining audio clarity in group calls. Therefore this option cannot be the correct answer.
