Which sentence is the best example of a lively and active voice?

1.) we were invited by our neighbors to attend the cookout.

2.) hey machine mixes the concrete with water.

3.) her parents had already been informed.

4.) the ballots were counted by a member of committee.

the answer is actually 2 because it doesn't use a past tense verb

2) Hey machine mixes the concrete with water.

 The verb in this sentence (2) is in the active voice. Hey machines (subject) are doing the action of mixing. There are two different ways to use the verbs: The active voice to express clearly who did the action or the passive voice to make less open who did it. The verbs in the other sentences are passive verbs: 'were invited', 'had been informed' and 'were counted'.

so is this a rhetorical question?
