(1)It is possible to assign each of 3n students to one of m classrooms so that each classroom has the same number of students assigned to it.

(2)It is possible to assign each of 13n students to one of m classrooms so that each classroom has the same number of students assigned to it.

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.

我觉得是说n个学生平均分配到m个教室即n是否可以被m整除
1.3n/m是整数举例 n=40 m=6
n=42 m=6 都成立 1不充分
2.13n/m是整数 m小于13 那么这个式子成立的唯一可能是n/m是整数

我觉得选B吧
