Q24: Is │x│=│y│? (1) x
-
y = 6 (2) x
+
y = 0 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. 答案是B我觉得是D 由（1）得出x＝6＋y，显然x与y的绝对值不相等，结论非常确定。 数据题考的是从条件是否得出唯一确定的答案，而不管答案是否定还是肯定。就像这题，否定了等式也是一个肯定的答案啊！ 请帮我看看，也许我正糊涂忘了（1）有其他的可能性了。谢谢！！！ |
