问一个很重要的问题——对DS题目的理解
先说一下我的理解:DS要求是看选项中有没有能给出题目确定的结果的答案,那么就有一个问题:如果本身这个题是一个多解题,通过选项可以确定出这些解,而且可以肯定只有这几个解,算不算正确呢?比如GWD1 16
Q16:
If J, S, and V are points on the number line, what is the distance between S and V?
(1) The distance between J and S is 20.
(2) The distance between J and V is 25.
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.
这道题的确是有两个解,而且是肯定的两个解,但是为什么选E呢?DS的要求到底是什么呢?
