The sentence that uses passive voice is the following one: We were given new toothbrushes by the hygienist.

Explanation:

In most English sentences with an action verb, the subject carries out the action denoted by the verb. Since the subject acts upon the verb in such sentences, the sentences are said to be in the active voice. You can change the word order of the active sentences for the subject to be no longer active, but being acted upon the verb. In such a case, the sentences are said to be passive, just as the sentence above. You can construct a passive voice sentence by moving the active sentence's direct object into the subject slot, then placing the active sentence's subject into a by-phrase, and finally adding a form of auxiliary verb be to the main verb and changing the main verb's form.
