做了gwd31套的第一套,错了4个,郁闷,不过有一题答案好像给错了,第30题: Q30: Joanna bought only $0.15 stamps and $0.29 stamps. How many $0.15 stamps did she buy? (1) She bought $4.40 worth of stamps. (2) She bought an equal number of $0.15 stamps and $0.29 stamps. 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. 这个题我觉得应该选A啊,单独的(2)肯定是不能确定的嘛,怎么答案给了D呢,牛人指点一下应该是A吧? |
