以下是引用persistent在2006-8-12 15:47:00的发言: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. 我觉得应该是c啊,知道J-S和J-V之间的距离,无论J,S,V怎么在数轴上排顺序,S-V距离都应该能算出啊,为什么答案是E呢? GMAT要唯一 |
