问题
p, q, r, and s are the coordinates of the points indicated on the number line.

Column A                   Column B
p+q                        r+s

选项 A、if the quantity in Column A is greater
B、if the quantity in Column B is greater
C、if the two quantity are equal
D、if the relationship cannot be determined from the information given

答案B

解析 25.p,q,r和s是左面数轴上所指示的点的坐标。
解:本题的正确答案是(B)。美国数学中所有的数轴都画成双箭头,但不管是单箭头还是双箭头,所有的数轴都是由左至右递增的,所以本题显然有r+s>p+q。
