Question

is this sentence in active voice or passive voice? in 1949, the u.s. food and drug administration approved the first drug for the treatment of cancer: the chemical compound hn-2. active voice passive voice

Explanation:

Active voice has a subject performing the action (subject + verb + object). Here, "the U.S. Food and Drug Administration" (subject) performs "approved" (verb) on "the first drug" (object). Passive voice uses "be + past participle" and reverses subject-object roles, which is not present here.

Answer:

active voice
