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.
The visual aid which would best engage the audience's emotions is the following one:
B. A short clip from an episode of a classic television show.
Since we are talking about a <em>classic</em> television show, people are likely to be familiar with it and it must have been, at some point, part of their lives as a source of entertainment and also as something they related to somehow. Due to the fact they have already watched it and probably know the characters well, it has certainly triggered their emotions throughout their lives, in different stages of it. Watching a short clip of the classic TV show can surely engage the audience's emotions, whether by making them laugh or by reminding them of some personal event, perhaps leading them into a feeling of nostalgia.
