Active-Passive voice Questions and Answers

Answer: C

The correct passive is By whom were you asked to draft this letter ?

In the active question Who asked you...? the subject is who and the verb is in the simple past. In the passive, who becomes by whom, the object you becomes the subject, and the verb becomes were asked, with question word order (auxiliary before subject).

Option A changes the tense to present, B uses who after a preposition and the present perfect, and D keeps statement word order (you were) in a question.

Answer: A

Correct answer: After being driven to the museum, Professor Kumar was dropped at his hotel.

Both clauses go passive together. The participial phrase after driving becomes after being driven, and it must attach to the new subject - Professor Kumar - which is exactly why the option keeping she as subject leaves a dangling modifier. Dropped him then becomes was dropped.

Answer: B

Correct answer: I remember being taken to the museum by my sister.

The verb remember takes a gerund, so the passive must also be a gerund: being taken. I remember I was taken replaces the gerund with a clause, and myself being taken adds a reflexive the construction does not need.

Answer: D

Correct answer: By whom is this mess being created?

Three things must hold at once: the tense stays present continuous, so the passive is is being created; the interrogative subject who becomes the agent by whom; and because it is a question the auxiliary comes before the subject. Only the keyed option does all three.

Answer: B

Correct answer: I am greeted cheerfully by them every morning.

The present simple greet becomes am greeted - a habit, so not the continuous. Was greeted shifts to the past, and am being greeted turns a daily habit into something happening now.

Answer: C

Correct answer: Tea is grown in Darjeeling.

Grows is present simple, so the passive is is grown. The agent Darjeeling is a place, so it appears with in rather than by. Tea grows in Darjeeling is active again, and let the tea be grown turns a statement into a command.

Answer: B

Correct answer: A perfect dam has been built by them across the river.

The present perfect have built becomes has been built, agreeing with the new singular subject a perfect dam. The past-tense and modal options change when the building happened or whether it happened at all.

Answer: B

Correct answer: Are others imitated by you?

The present simple question do you imitate becomes are others imitated. The auxiliary do disappears into the passive are, and the question order is kept because the sentence is still a question.

Answer: C

Correct answer: Your shoes need to be cleaned properly.

Need here is followed by a passive infinitive: what needs doing is the cleaning, and the shoes are what gets cleaned. The options making you or your shoes the thing needed reverse which part of the sentence is passive.

Answer: B

Correct answer: People say he is very rich.

Turning a passive into the active requires an agent, and where none is given English supplies an indefinite one - people. He is said to be then unpacks into the clause he is very rich. The options with it lose the person the sentence is about.
