Q10:
A set of numbers has the property that for any number t in the set, t + 2 is in the set. If –1 is in the set, which of the following must also be in the set?
I. -3
II. 1
III. 5
A. I only
B. II only
C. I and II only
D. II and III only
E. I, II, and III
第10题的答案是D的说，但是我觉得可以选E呢。因为t+2=-1的话，那-3就可以存在了呀~作者: xiongbaobao 时间: 2010-6-25 17:11
个人理解是，只能正着推，不能倒回来推。
T是条件,T+2是个结果。
个人理解，仅供参考
