LSAT 8-2-7

Scientists are sometimes said to assume that something is not the case until there is proof that it is the case. Now suppose the question arises whether a given food additive is safe. At that point, it would be neither known to be safe nor known not to be safe. By the characterization above, scientists would assume the additive not to be safe because it has not been proven safe. But they would also assume it to be safe because it has not been proven otherwise. But no scientist could assume without contradiction that a given substance is both safe and not safe: so this characterization of scientists is clearly wrong.

Which one of the following describes the technique of reasoning used above?

(A) A general statement is argued to be false by showing that it has deliberately been formulated to mislead.

(B) A statement is argued to be false by showing that taking it to be true leads to implausible consequences.

(C) A statement is shown to be false by showing that it directly contradicts a second statement that is taken to be true.

(D) A general statement is shown to be uninformative by showing that there are as many specific instances in which it is false as there are instances in which it is true.（B）

(E) A statement is shown to be uninformative by showing that it supports no independently testable inferences.

我选B,
第一要哪个确定THE STATEMENT: so this characterization of scientists(Scientists are sometimes said to assume that something is not the case until there is proof that it is the case) is clearly wrong.
A)deliberately .. mislead-- 看不出故意的成分.
B) implausible consequences. -- 成分文中的确举了一个例子来
C) a second statement -- 我只看见一个STATEMENT
D) many specific instances -- ONLY one example shows here
E) no independently testable inferences. -- 好象离题太远了吧?

楼主个贴一下标准答案吧.
