Question

which sentence uses the passive voice for the main verb?

• 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.

Explanation:

Passive voice structures follow the pattern "be + past participle" where the receiver of the action becomes the subject. Analyzing each option:

1. First sentence: Active voice (teacher = subject, confiscates = active verb).
2. Second sentence: Active voice (students = subject, slide = active verb).
3. Third sentence: Passive voice (mythology = receiver of "choose", "is chosen" follows "be + past participle" structure).
4. Fourth sentence: Active voice (students = subject, perform = active verb).

Answer:

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