Read the paragraph.
(1) after our trip, the skyscraper visit was unanimously voted as our favorite.
(2) the museum was supposed to be the highlight of the trip.
(3) but those works of art were completed a long time ago.
(4) at the skyscraper, we watched them in action building their masterpiece.
which sentence in the paragraph is in the active voice?

4). At the skyscraper, we watched them in action building their masterpiece.

Explanation:

As per the question, option 4 displays the sentence that is written in active voice as the subject/doer is accomplishing the action expressed by the verb in the sentence which is contrary to the sentence written in passive voice which involves a subject that receives the action or being acted upon(by the verb). Options 1, 2, and 3 emphasizes the object('the skyscraper visit', 'the museum', and 'those works of art') instead of the subject which implies that they are the recipient of the action. Thus, only option 4 contains the subject 'we' that is performing the action 'watched' rather then receiving it. Therefore, option 4 is the correct answer.

that is true because that is something they fulfill for their work.
