Choose the correct passive voice transformation of the sentence:
We saw the new CEO enter the conference room just as the meeting was about to begin.
Show answer & explanation
Correct answer: B
Explanation
When transforming an active voice sentence with a verb of perception (like 'saw') followed by a bare infinitive ('enter') into the passive voice, the bare infinitive changes to a to-infinitive. The object of the active sentence ('the new CEO') becomes the subject of the passive sentence, and the active subject ('we') becomes the object of the preposition 'by' ('by us').
The original active sentence is:
We (Subject) saw (Verb of perception) the new CEO (Object) enter (Bare infinitive) the conference room...
The correct passive transformation is:
The new CEO (New Subject) was seen (Passive verb) to enter (To-infinitive) the conference room... by us (Prepositional phrase).
