Answer: Sentences 2, 4 and 5 are written in passive voice.
Explanation:
We use passive voice when we want to put an emphasis on the action and the object, rather than subject. In other words, subject is either insignificant in that particular case, or we do not know who/what the subject is. The object from the active sentence becomes the subject in the passive sentence.
For example, active sentence is: <em>One of my favorite authors wrote </em><em><u>that book</u></em>, while passive sentence is: <em><u>That book</u></em><em> was written by one of my favorite authors</em>.
We form passive from the auxiliary verb (often verb <em>to be</em>) and past participle.
