问题 The average (arithmetic mean) of x and y
Quantity A: s+2
Quantity B: y-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 B

解析 Quantity A-Quantity B=(x+y)/2-(y-1)=(x-y+2)/2,根据x<y-2,得x-y+2<0,差为负数,所以Quantity A<Quantity B,故答案为B。
