Question

is this sentence in active voice or passive voice?
some foods—such as beans, nuts, and whole grains—are digested more slowly than others.
active voice
passive voice

Explanation:

In the sentence "Some foods—such as beans, nuts, and whole grains—are digested more slowly than others", the subject ("Some foods") is the one that is being acted upon (digested), and the verb "are digested" follows the passive voice structure (form of "be" + past participle). In active voice, the subject performs the action, but here the subject is receiving the action of digestion.

Answer:

passive voice
