请教两个GWD的数学题！麻烦大家帮忙看看是答案错了么？
1.If k is a positive integer, is k the square of an integer?
(1)k is divisible by 4.
(2) k is divisible by exactly 4 different prime numbers.
答案：E
但是我觉得第二个条件就直接可以知道问题是错的啊，你想k被四个完全不同的质数除尽，那他肯定不是任何数的平方啊。。。
2. What is the median number of employees assigned per project for the projects at Company Z?
(1)25 percent of the projects at Company Z have 4 or more employees assigned to each project.
(2) 35 percent of the projects at Company Z have 2 or fewer employees assigned to each project.
答案：C
但是我觉得就算条件1+条件2知道中数出现在条件2的范围里，但是条件2是个范围啊，还是没有办法知道确定的值的嘛。。。
求高手指点下！！ |
