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.
Answer: c
完全不懂怎么做，感觉应该是我理解题意。。中位数怎么可以从中求出呢？

一首简单的越歌

可以画出一条线段，线段的0%至35%部分代表人数小于等于2，线段的75%到100%代表人数大于等于4，那么夹在35%和75%这部分的人数就只可能是3了，而中位数就是位于50%的位置，即3个人。所以必须利用1和2两个条件才能求解。
