Answer: E
Passive Voice, Parallel Structure

Both (A) and (C) can be eliminated because they contain passive constructions that make the sentence unnecessarily awkward and that disrupt the structure of the sentence: the subject of the previous clause is people, and the underlined clause should ideally begin with they  (i.e., people) to keep the structure parallel. (B) and (D) can be eliminated because the pronoun this must be followed by a noun – left on its own, this word is ambiguous and virtually always signals an incorrect answer. In addition, the gerund being in (D) also signals an incorrect answer. That leaves (E), which maintains parallel structure and provides a clear, active construction.
