Question

is this sentence in active voice or passive voice? dairy products were consumed by north africans as early as seven thousand years ago. active voice passive voice

Explanation:

To determine the voice, we analyze the sentence structure. In "Dairy products were consumed by North Africans...", the subject (dairy products) is the receiver of the action (consumed), and the agent (North Africans) is introduced by "by", which is characteristic of passive voice. Active voice has the subject performing the action, which is not the case here.

Answer:

passive voice
