The chorus in a play, like a narrator in a novel, introduces a point of view not tied to any of the characters, and both chorus and narrator allow the author to comment on the characters' actions and to introduce information about the context in which these actions take place. However, since the information introduced by the chorus in a play is sometimes not consistent with the rest of the information in the play, the chorus in a play is not equivalent to the narrator in a novel.
Which one of the following is an assumption on which the argument depends?The argument says the chorus and narrator are similar in several ways, but then concludes that they are not equivalent because the chorus can introduce information inconsistent with the rest of the play.
The key missing link is that narrators in novels do not do this. Otherwise, the stated difference would not separate the chorus from the
novel narrator.
(A) The narrator in a novel is never deceptive.
This is too broad and not precise enough. The issue is not deception in general; the issue is whether the narrator’s information can be inconsistent with the rest of the novel.
(B) The voice of a narrator is sometimes necessary in plays that employ a chorus.
This is irrelevant. The argument compares choruses in plays with narrators in novels.
(C) Information necessary for the audience to understand events in a play is sometimes introduced by the chorus.
This may be true, but it does not support the claimed difference between chorus and narrator.
(D) Information introduced by a narrator in a novel can never be inconsistent with the rest of the information in the novel.
This is correct. If narrators in novels could also introduce inconsistent information, then the chorus’s inconsistency would not show that the chorus is not equivalent to the narrator.
(E) Authors sometimes use choruses in plays to mislead audiences about events in the plays.
This is not required. The argument needs inconsistency to distinguish chorus from narrator, not intentional misleading.
Answer: (D)
