再问一题PP~觉得有可能考类似题

175. 

The sum of the integers in list S is the same as the sum of the integers in list T.  Does S contain more integers than T ?

(1)  The average (arithmetic mean) of the integers in S is less than the average of the integers in T.

(2)  The median of the integers in S is greater than the median of the integers in T.

PREP的答案是A

我选E

我的想法=>若list S 和 T 的总和都是-30的话  

                     在1)的条件下,S的数量必定要比T少

                     若list S 和 T 的总和都是30的话

                     在1)的条件下,S的数量必定要比T多

                      请问各位我的想法有错吗??
