little_fox

2.there are two sets, x and y. x is composed of multiples of 2, and y is composed of multiples of 4, is it possible for interger m be of x while not of y ? (1) m is even. (2)m/2 is odd
B

问是否可能，（1）也可能阿，

(1)并没有给一个肯定的答案，这是ETS所不想要的，所以(1)不考虑。

请教

But the question is the possibility but necessary.
To (1), it is possible to m be of x while not of y.

Please check. Thax!

那么我说m是一个integer，也可能了。这不是充分条件，这道题本身问的有些问题，所以考虑ETS的思路，最好还是选B

Make sense.

Thank you!
