1. Quantity A：x2 + y

Quantity B：x2 – y

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

虽然已知x2是正的，但无法判定y的正负，根据y的正负结果也会变化，因此是不确定。

2. Quantity A：The least positive integer that is divisible by both 14 and 21

Quantity B：The least positive integer that is divisible by both 14 and 28

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：C

通过计算可知，能同时被14和21整除的最小整数是1，而能被14和28整除的最小整数也是1，所以显然A和B一样大。

3.

Quantity A：x

Quantity B：y

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

只从PQ=RT而不清楚QR的长度，是无法判断x和y的度数大小的。

4. Mrs. Jones sold two houses for $80,000 each. One house was sold at a 20 percent loss and the other at a 20 percent gain.

Quantity A：The gain minus the loss

Quantity B：0

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

通过计算可知：gain=80000-80000/1.2;loss=80000/0.8-80000，显然损失的比赚的多，所以用gain-loss也就小于0。

5.

Quantity A：x+y

Quantity B：w+z

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：C

四边形内角和为360°，那么360°-(x+y)和360°-(w+z)是一样多的。
