Which of these sentences uses active voice?

Question

At noon, some cookies were going to be baked by the baker.

My friend invited his whole class to Saturday's soccer championship.

The winning homerun was hit by the worst player on the baseball team.

The children were taken to the circus by their doting grandfather.

Answer 1

The sentence that uses active voice is:

"My friend invited his whole class to Saturday's soccer championship."

In this sentence, the subject (my friend) performs the action (invited) directly. The other sentences use passive voice, where the subject receives the action rather than performing it.
