问题 When integer n is divided by 9, the remainder is 2.

Column A                   Column B
The remainder when            2
n is divided by 3
选项 A、if the quantity in Column A is greater
B、if the quantity in Column B is greater
C、if the two quantity are equal
D、if the relationship cannot be determined from the information given
答案C
解析 整数n被9除时，余数(remainder)为2。n被3除的余数2。
解：本题的正确答案为(C)。根据题意整数，n可以表示为：n=9m+2，其中m是整数，显然9m可以被3整除，所以n被3除时余数仍为2。
