Which sentence uses the passive voice for the main verb?

Question

If we use our cell phones during class, the teacher confiscates them.
When they can, students slide down the banister in the science wing.
When we can pick our reading, mythology is most often chosen in my class.
If they choose to participate, students perform their poems at the poetry slam.

Answer 1

The sentence that uses the passive voice for the main verb is:

"When we can pick our reading, mythology is most often chosen in my class."

In this sentence, "mythology is most often chosen" is in the passive voice, as the subject (mythology) is receiving the action of being chosen rather than performing it.
