There are two main things to keep in mind when trying to
determine whether a sentence is written in the passive voice or if it is
written in the active voice. First, passive
voice is when the subject has the action done to it, and active voice is when
the subject does the action. Second,
passive voice will always have linking/helping verbs. That said, answers, “A,” “C,” and “D” have
the action being done to the subject, and all three have linking/helping verbs
in the form of “are” and “be.” “B” is
the only answer where the subject (in this case, “people”) is doing the action
of “think” and has not linking/helping verbs.
