which sentence is active voice

Question

A hike is done every weekend by Gigi.

Every weekend, a hike is done by Gigi.

Gigi hikes every weekend.

By Gigi, a hike is done every weekend.

Answer 1

"Gigi hikes every weekend" is active voice, but this is not the best example question for active versus passive voice. The "hike" is not the subject, it does not perform an action on Gigi. The verb phrase "is done" shows that it is passive voice. A verb such as "do" or "does" would show active voice.
