Question

What is the best way to put the sentence in the active voice while still maintaining its meaning?

Before the main performance, the comedian was entertained by the audience.

Answer 1

Either:

Before the main performance, the audience entertained the comedian.

Or:

The audience entertained the comedian before the main performance.

Up to you which sounds better or seems closer to the original. Active voice usually just means avoiding words that make the person doing the action not the subject (i.e. The audience doing the entertaining not the subject (the comedian))

These options retain as much of the original sentence as possible, but synonyms aren't bad if you want to use them either

Answer 2

Answer: B

Explanation: The given sentence is in passive form because the receivers of the action became the subject of the sentence. To transform this to active voice, the doer of the action should be the subject of the sentence such that the sentence can be written as,

           Before the main performance, the comedian entertained the audience.
