问题 Each of Questions 1 to 7 presents two quantities. Quantity A and Quantity B. Compare the two quantities. You may use additional information centered above the quantities if such information is given. Choose one of the following answer choices:
A if Quantity A is greater;
B if Quantity B is greater;
C if the two quantities are equal;
D if you cannot determine the relationship based on the given information.

选项 A、 
B、 
C、 
D、 
答案A
解析 The correct answer is A. To solve this problem, determine how the quantity x-y compares to 0, given that x is a negative integer and y is a positive integer. Because x is a negative integer, subtracting a positive integer from it would yield another negative integer with a greater value; therefore, the quantity x-y<0, and Quantity A(0)is greater than Quantity B(x-y).
