Q32:
Is x an odd integer?
(1) x + 3 is an even integer.
(2) x/3 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.
答案是d,但是,我认为(1)中如果x是负3则x+3=0,是非奇非偶。
我选答案e |
