EXAMINE THE FOLLOWING SENTENCE AND CHOOSE THE APPROPRIATE DESCRIPTION.

1.Both clauses are in active voice
2.Both clauses are in passive voice
3.The first clause is active,the second
clause is passive
4.The first clause is passive,the second
clause is active.

Would the answer be (B)both clauses are in passive voice?

Remember this rule:
A form of "to be" + past participle = passive voice

has been + repaired = passive
will be + returned = passive

Both clauses are passive. The subject of the clause (machine/it) is acted upon, but does not act perform the action.
