Which number in set P have a value greater than that of every other member of set P,if all the members of set P are negative integers?
(1)Each member of set P is the product of -1 and a prime number.
(2)At least one member of P is even.
我选E，因为我觉得可能是-1，或-2

A
因为1不是质数。

哦，我就要确认这个，呵呵：）

我坚持这个想法。

星月多多

什么想法？：）
答案选C，
因为1只说了Each member of set P is the product of -1 and a prime number，并不是说和所有的质数，所以应该还要加上2条件，才能确定

我改口了，就是你现在的答案。
