Question

which sentence is in passive voice? on april 18, 1906, san francisco was devastated by an earthquake and its fiery aftermath. on april 18, 1906, an earthquake and its fiery aftermath devastated the city of san francisco.

Explanation:

Passive voice structures use "be + past participle" and place the receiver of the action as the subject. The first sentence has the structure "was devastated" (be + past participle), with San Francisco (the receiver of the devastation) as the subject, and uses "by" to introduce the cause of the action. The second sentence uses active voice, with the earthquake (the doer of the action) as the subject.

Answer:

On April 18, 1906, San Francisco was devastated by an earthquake and its fiery aftermath.
