Question

Change the following sentence into passive voice.
Somebody will clean the office tomorrow.

• A. The office would be cleaned by somebody.
• B. The office will be cleaned tomorrow.
• C. Somebody will be cleaning the office tomorrow.
• D. None of the above.

Answer 1

Answer: (B)

The office will be cleaned tomorrow.

The sentence is in the active voice when the subject does the action. In passive voice, the subject receives the action.
In the given sentence, 'somebody' is the subject who does the action 'will clean'. When the subject pronouns used are indefinite, like somebody, nobody, anybody, they, etc., then in the passive voice form the subject is omitted.
Thus, when the given sentence is changed to passive, the subject 'somebody' is omitted and the answer is: The office will be cleaned tomorrow.
Hence option B is correct and A is incorrect.
Option C is incorrect because the voice has not changed to passive. Instead, the tense has changed from future simple to future continuous.
Option D is incorrect because the answer lies in B.
