问题 n is an integer, and k is not an integer.
0＜k＜n＜k+2
Quantity A: n
Quantity B: k+1
选项 A、Quantity A is greater.
B、Quantity B is greater.
C、The two quantities are equal.
D、The relationship cannot be determined from the information given.
答案 D
解析 本题可使用列举法答题。k=0.9，k+2=2.9→n=1或n=2，k+1=1.9→n＞k+1或n＜k+1，故答案为D。k是整数，n是非整数，所以n≠k+1。
