UGC NET Questions (Paper – 1)

Statements A, B and D are correct, while C is the only wrong statement. A is correct because noise refers broadly to any interference that distorts a message between sender and receiver. B is correct since redundancy, such as repeating key ideas, can help messages survive the effects of noise. D is correct as using multiple examples for the same concept is a practical form of redundancy in teaching. C is wrong because in real educational settings it is rarely possible to eliminate all forms of noise completely.

Option A:
Option A is incorrect because it lists A and C as wrong statements. A is actually a standard definition of noise as interference with the message. Although C is wrong, picking both A and C makes the combination inaccurate.

Option B:
Option B is incorrect because it groups B and C as wrong statements, even though B is a correct statement about the protective role of redundancy. Classifying B as wrong undermines the recognised function of redundancy in communication, so B and C only cannot be accepted.

Option C:
Option C is incorrect because it identifies C and D as wrong. While C is wrong, D accurately points out that multiple examples can serve as redundancy to reinforce a concept. Including D as wrong makes this option logically inconsistent.

Option D:
Option D is correct because it singles out C only as the wrong statement. C unrealistically claims that complete elimination of noise is always possible in educational communication. By keeping A, B and D outside the wrong set and recognising them as correct, this option aligns with communication theory.

Noise is any unwanted interference that distorts or obscures the message as it travels through the channel. Loud construction sounds outside the classroom reduce students' ability to hear the teacher's words clearly. This is a typical case of physical noise in the environment. Therefore,"noise" is the appropriate term.

Option A:
Redundancy refers to deliberate repetition of information to improve clarity,not to disruptive sound. The construction noise does not reinforce the message; it obstructs it.

Option B:
Feedback is the receiver's response that goes back to the sender,rather than an interfering sound.

Option C:
Encoding is the sender's process of translating ideas into symbols,which is separate from environmental disturbances.

Option D:
Because the interference comes from external sounds disrupting hearing,it matches the definition of noise in communication theory.

In communication theory,noise is a technical term for anything that interferes with accurate transmission of a message. It may be physical sounds,technical faults or even faulty handwriting. Such interference distorts or masks the intended meaning. Therefore,the unwanted factors mentioned in the stem are collectively called noise.

Option A:
Channel refers to the medium that carries the message,such as airwaves,cables or paper. While noise may affect a channel,the channel itself is not the source of distortion. Hence this option does not match the stem.

Option B:
Feedback is the receiver’s response that returns to the sender and helps evaluate effectiveness. It is not an interfering element and therefore is the opposite of what the stem describes.

Option C:
Redundancy refers to repetition or extra signals built into a message to make it more robust,not to interference. Often redundancy helps overcome noise rather than causing it. So it does not fit the idea of unwanted disturbance.

Option D:
Noise explains why even carefully encoded messages may be misunderstood,because the signal gets disturbed on the way to the receiver,making option D correct.

Statements A and B are correct, whereas C and D are wrong and therefore form the correct combination of wrong statements. A is true because physical noise includes sounds such as traffic or construction that interfere with hearing a message. B is true since internal factors like prejudice and bias may distort how messages are interpreted and thus act as psychological noise. C is false because noise can arise at any point in the communication process, including at the receiver’s side. D is false because rigid rules and hierarchy may obstruct free flow of information and thus create a kind of organisational noise.

Option A:
Option A is incorrect because it treats C only as the wrong statement and overlooks D. While C is indeed wrong, D also misrepresents the possibility that organisational structure can interfere with communication. Leaving D out means this option does not capture all the wrong statements.

Option B:
Option B is incorrect because it selects D only as wrong and ignores C. Although D is a false statement, C is equally incorrect in claiming that noise never originates from the receiver. Since the question asks for all wrong statements, an option that includes only D cannot be accepted.

Option C:
Option C is correct because it groups C and D, the two statements that misrepresent the nature and sources of noise. It recognises that both the sender and receiver, as well as organisational structures, can contribute to noise in communication. By excluding A and B, which are accurate descriptions of physical and psychological noise, this option exactly matches the set of wrong statements.

Option D:
Option D is incorrect because it includes A, C and D as wrong statements. A is actually a correct statement defining physical noise as external sound interference. Including A among wrong statements makes this combination overinclusive and inconsistent with communication theory.

Noise is any unwanted interference that distorts or obscures the message while it travels through the channel. Loud traffic entering through the window makes it difficult for students to hear the teacher clearly. This external sound therefore functions as noise in the communication process.

Option A:
Feedback is the receiver's response and is purposeful,unlike random traffic sounds.

Option B:
Channel is the medium such as air or electronic signals and is not itself the interference.

Option C:
Because the example highlights environmental sound reducing clarity,noise is the correct term.

Option D:
Redundancy is used to reinforce messages,whereas noise undermines them.
