标题: [讨论] TAOTAO 4-32: 0是不是偶数?

Q32:

Is the integer n even?

(1)
n – 5 is an odd integer.

(2)
n/5 is an even 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.

这题答案是D, 我选了B. 在判断(1)的时候, n=0也满足条件, 但0究竟算不算是偶数呢?
