今天做GWD5－M－Q32时，突然发现一个细节问题，到底负数有没有奇偶之分呢？请教了，引发这个问题的题目附录于下：

Q32:

Is x an odd integer?

(1) x + 3 is an even integer.

(2) 3/X is an odd integer.

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. EACH statement ALONE is sufficient.

E. Statements (1) and (2) TOGETHER are NOT sufficient.
