Re-write the following sentences according to the instructions given after each. Make other changes that may be necessary, but do not change the meaning of each sentence.
The school captain was elected by the students of classes XI and XII. (Begin: The students ...........)
Topic: Passive to active voice
Answer
The students of classes XI and XII elected the school captain.
The instruction makes the agent the subject, so this is PASSIVE into ACTIVE.
Passive: The school captain WAS ELECTED BY the students... Active: The students... ELECTED the school captain.
THE RULE: keep the tense. "Was elected" is simple past, so the active verb is "elected" — not "have elected" or "had elected".
The word BY disappears in the active voice, because the agent has become the subject and no longer needs to be marked.
Note that the qualifying phrase "of classes XI and XII" travels with "the students" — it belongs to them, not to the sentence.
