Question

which sentence uses passive voice?
○ we arrived early for our annual dental check-ups.
○ dr. gomez greeted us warmly and took x-rays.
○ calm music played quietly in the dentists office.
○ we were given new toothbrushes by the hygienist.

Explanation:

Passive voice structures focus on the receiver of an action, typically using "be + past participle" and often including the doer with "by". The first three sentences use active voice, where the subject performs the action. The last sentence has the subject "We" receiving the action "given", with the doer "the hygienist" introduced by "by", fitting passive voice rules.

Answer:

We were given new toothbrushes by the hygienist.
