Which of following equations individually sufficient provide(s) whether U>W?
A:U=|W|
B:W=|U|
C:U>0
D:W>0
E:UW>0
答案是B
我想知道题目是什么意思,哪个是条件,哪个是推导出来的结果?为什么选B呢?我觉得一个都不对。
还有一道题目,如下:
If the product of 5 consecutive integers is not zero,which of following statements individually sufficient provide(s) whether the product of these 5 integers is negative?
A:The greatest number is less than 5
B:At least one of them is less than 0
C:None of them is positive
