Voice — Active to Passive conversion MCQ — 15 Practice Questions with Answers

Explanation

The present continuous passive is formed with 'is/am/are + being + past participle'. The cue is 'is preparing' and the time marker 'now', so the passive must be 'is being prepared'. Option B uses 'was being prepared', the past continuous passive, which clashes with the given present-time sentence; hence it is the only incorrect option.

Explanation

A simple past passive interrogative is formed as 'was/were + subject + past participle'. The active sentence 'Did the manager approve the proposal?' becomes 'Was the proposal approved by the manager?'. Only option A is grammatically incorrect because it keeps the base verb 'approve' instead of the past participle 'approved'.

Explanation

The simple present passive is formed with 'is/am/are + past participle'. The active object is 'the applications', a plural noun, so it becomes the passive subject and takes 'are'. Therefore, 'checks' changes to 'are checked', making only 'The applications are checked carefully by the clerk' correct.

Explanation

The present perfect passive is formed as 'has/have been + past participle'. The cue is the active verb phrase 'has dispatched', which must become 'has/have been dispatched'. Since the passive subject 'the letters' is plural, the auxiliary must be 'have'. Therefore, only 'The letters have been dispatched by the clerk' preserves the tense and meaning correctly.

Explanation

The passive form of the future simple tense is 'will be + past participle'. The cue 'will announce' shows future simple, and the active object 'the result' must become the passive subject. Therefore, only 'The result will be announced by the committee tomorrow' preserves the meaning and uses the correct future passive form.
