14. Some of the world's most beautiful cats are Persian cats. However, it must be acknowledged that all Persian cats are pompous, and pompous cats are invariably irritating.
If the statements above are true, each of the following must also be true on the basis of them EXCEPT:
(A) Some of the world's most beautiful cats are irritating
(B) Some irritating cats are among the world's most beautiful cats
(C) Any cat that is not irritating is not a Persian cat
(D) Some pompous cats are among the world's most beautiful cats
(E) Some irritating and beautiful cats are not Persian cats
why E not C?这种题目有无妙法可解？作者: zyh79 时间: 2002-10-28 11:46
题目的意思是：所有的Persian==>pompous,而且所有的pompous==>irritating
所以：Some irritating are not Persian 错！
妙解不知道，有这样的一句话
弄清推理关系，把握some,all。
