OE for reference:Overview: We are told that, because it is set in the future, the great dramatic novel
The Time Machine is classified as science fiction. The argument concludes, though, that this classification is inappropriate. It supports this conclusion with the statement that, like other great dramatic novels,
The Time Machine has a feature that science fiction generally does not—its compelling characters. The conclusion of this argument follows logically if an assumption is added to the argument; your task is to identify that assumption.
The Correct Answer:
E The argument states that
The Time Machine is a great dramatic novel, while (E) indicates that dramatic novels cannot be both great and science fiction. From these claims, it follows logically that
The Time Machine is not science fiction. Therefore, as the argument's conclusion indicates, it is not appropriate to classify it as such.
The Incorrect Answer Choices:A Since the argument does state that
The Time Machine contains compelling characters, (A) allows us to infer that it is a great dramatic novel. But the argument already says that
The Time Machine is a great dramatic novel. Moreover, the statement that
The Time Machine is a great dramatic novel is compatible with the possibility that it is
also science fiction. So the argument's conclusion does not follow logically when (A) is assumed.
B Even if all novels can be clearly classified into distinct genres, it could be that
The Time Machine can be clearly classified as
both science fiction
and a dramatic novel. And even if (B) is interpreted as the stricter claim that all novels can be classified into
one distinct genre, that genre could be science fiction. So assuming (B) does not suffice to establish the argument's conclusion.
C (C) makes a claim about science fiction works: they cannot be great unless their characters are compelling. Since the argument indicates both that
The Time Machine has compelling characters and that it is a great dramatic novel, (C) is compatible with the possibility that
The Time Machine is science fiction. So (C) does not help establish the argument's conclusion.
D The argument tells us that
The Time Machine has compelling characters, so (D) might be taken to suggest that this novel is of high quality. But this does not help us address the question of whether it is appropriate to classify
The Time Machine as science fiction, so the argument's conclusion does not follow logically when (D) is assumed.
