The error is in the first part of the sentence. In the first part preposition ‘with’ should be replaced by ‘in’. Note that we can use two prepositions with the word ‘acquiesce’ means to ‘accept something reluctantly but without protest’, which are ‘in’ and ‘to’. When used with ‘in’, it shows a passive agreement with something. And when used with ‘to’, it means ‘to submit voluntarily to a thing, situation or condition’. Note that using it ‘with’ is not advisable.

Hence, option A is correct.

The error is in the second part of the sentence. In the second part of the sentence, instead of preposition ‘with’ preposition ‘from’ should be used. ‘Part with’ means ‘to give up something or let go of something’ whereas ‘part from’ means ‘to separate from someone’. One more variant is:

Parted away means to separated or moved away, which is again a misfit here.

As, the sentence implies the second meaning.

Hence, option B is correct.

The error is in the third part of the sentence.

‘Since’ should be used in place of ‘for’.

The preposition ‘for’ is used to mention an amount of time or space, which does not need to be exact. On the other hand, the preposition ‘since’ is used to refer to an exact point of time, which can be any past event or a specific time in the past, beginning sometime in the past and continuing until the present time.

Therefore, option C is the correct answer choice for this question.

The error is in the third part of the sentence.

The word ‘beside’ is a preposition, which means ‘next to’ or ‘at the side of’. The preposition ‘beside’ physically places two nouns side by side. Example: - Anirban sat beside Naina at the restaurant.

The word ‘besides’ can be used either as a preposition, meaning “in addition” or an adverb meaning “moreover.” Here in the given context it means “in addition to.”

Therefore, option C is the correct answer choice for this question.

The error is in the first part of the sentence. Amenable always takes the preposition ‘to’ after it. If a person or thing is amenable to something, they are ready, willing, or responsive. Therefore, 'amenable to' is the correct usage here. It means to be willing to.

‘For’ is incorrectly used in the third part of the sentence. If it was ‘defining’, then ‘for’ would have been correct. However, with ‘define’, the preposition that should be used is ‘to’.

The error is in the second part of the sentence. It is because the verb ‘discuss’ is a transitive verb. It should be followed by a direct object, and not a preposition. Therefore, ‘about’ must be removed to form a grammatically correct sentence. So, the correct answer is option B.

The error lies in the third part of the sentence. The preposition ‘on’ is contextually incorrect and needs to be replaced by the preposition ‘from’, indicating the source of something, which, in the case of the book, is the ‘second shelf’.

The error lies in the second part of the sentence. The preposition ‘with’, denoting ‘in regard to’, is contextually inappropriate. It needs to be replaced by the preposition ‘by’, which follows a passive verb, in this case ‘captivated’, to indicate the thing that does or causes something. In the case of the sentence, the thing that is causing the reaction in the audience is the ‘presentation’.
