Which of the following options is the most suitable conversion of the following sentence into Passive Voice?
How does he keep all these ancient clocks in working order?
Show answer & explanation
Correct answer: B
Explanation
The Sentence 'How does he keep all these ancient clocks in working order?' is in active voice.
To convert an interrogative sentence from active to passive voice, we follow these steps:
The sentence is in the Present Simple tense (indicated by 'does'). The passive structure for this is: is/am/are + past participle (V3).
The object of the active sentence is 'all these ancient clocks.' Since this is plural, we must use the auxiliary verb 'are.'
The main verb is 'keep.' Its third form (V3) is 'kept.'
We keep the question word 'How' at the beginning, followed by the auxiliary verb, then the new subject (the old object).
Structure: How + are + [object] + V3 + [rest of sentence] + by + [subject]?
Option ‘B’ follows all these rules.
