今日练习题为数学题，题目如下

Seven different numbers are selected from the integers 1 to 100, and each

number is divided by 7. What is the sum of the remainders?

(1)The range of the seven remainders is 6.

(2)The seven numbers selected are consecutive integers.

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 statement TOGETHER are sufficient, but NEITHER statement ALONE is

sufficient.

D EACH statement ALONE is sufficient.

E Statements (1) and (2) TOGETHER are NOT sufficient.

正确答案：

B

解题思路：

从7-100的数中，除7余数始终为0-6的循环

条件1：符合条件的可以先取两个余数分别为0和6的，剩下的数可以随便取，所以结果不确定，not sufficient。

条件2：任何连续的7个数除7的余数和一定等于0+1+2+3+4+5+6，所以sufficient。
