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.
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.

答案是E
这道题答案错了哦，需要考虑负数。所以答案是e不是a。请修正一下。

sum为负，average越小，个数越小 (1)应该insufficient
S：-100
T：-50；-50
sum相同，均值S小，含有的元素S少，这不是（1）的反例吗？
这题没人觉得有问题吗？没有说数列是正还是负啊
