Do integers P and T have the same number of different prime factors?
(1) p=5T/7     (2) PT =105
The answer is A ,but I think is D.Since PT=105=2*5*7,so P and T don't have the same number of different prime factors,so it can answer the question.

这是哪里的题?按道理ETS的题目所给的条件不会相悖,即根据1和2的条件得到的取值范围(或具体数值)是相同的.按你题目中的条件是得不到整数解的,和题目所给条件不符.所以题目有问题.
