Passive voice MCQ — 6 Practice Questions with Answers

Explanation

The sentence is in the simple past tense: "My sister baked a cake." In passive voice, the object "a cake" becomes the subject, and the verb changes to "was baked" because the subject is singular and the tense remains simple past. "Had been baked" shifts the sentence to past perfect, which changes the tense. "Is being baked" is present continuous passive, and "was being baked" is past continuous passive. Only "A cake was baked by my sister" preserves the meaning and tense.

Explanation

The active clause inside the sentence is “somebody was recording our conversation”. Its passive form is “our conversation was being recorded”, because the tense is past continuous. The main clause “I didn’t realise that” must remain, since the original sentence is about the speaker’s lack of awareness. “Our conversation was being recorded and it wasn’t realised” weakens the subject of realisation. “Somebody was recording our conversation was not realised” is ungrammatical. “Our conversation was being recorded by somebody” omits the main idea that the speaker did not realise it.

Explanation

The sentence is in the active voice with 'Everyone' as a general subject and 'the facts of the case' as the object. In passive voice, the object becomes the subject: 'The facts of the case are very well known.' 'The case is known' changes the focus from facts to the case itself. 'Everyone is known to the facts' is ungrammatical because people are not 'known to' facts in this structure. 'Everyone knows the facts' remains active voice, so it does not meet the instruction.

Explanation

The sentence has a gerund structure after “like”: the active phrase is “people telling me what to do”. In the passive, “telling me” becomes “being told”, while “what to do” remains the object of the instruction. “I don’t like being told what to do by people” preserves both the meaning and the grammatical pattern. “What not to do” changes the meaning. “People are being telling” is ungrammatical, and “what to do by the people” does not form a correct passive construction.

Explanation

The sentence needs a passive construction because the meter reader receives the action: the landlady takes him to be a burglar. The correct passive form is 'was mistaken', followed by 'for' to mean 'was wrongly identified as'. 'Mistook' is active past tense and would need the landlady as the subject. 'Was mistook' is ungrammatical because the past participle is 'mistaken', not 'mistook'. 'Has mistaken' is active present perfect and also leaves the sentence without a proper passive structure.
