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. Given that a<0, the quantity 1-a would be greater than 1, because subtracting a negative number has the effect of adding a positive number. The quantity a-1 is such that a number is being subtracted from a negative number, increasing the magnitude in the negative direction, thus the quantity is less than -1. Therefore, Quantity A is greater than Quantity B.
