test1-section IV-25
25. All of the best comedians have had unhappy childhoods. Yet, many people who have had happy childhoods are good comedians, and some good comedians who have had miserably unhappy childhoods are happy adults.
If the statements in the passage are true, which one of the following CANNOT be true?(A)
(A) The proportion of good comedians who had unhappy childhoods is greater than the proportion of the best comedians who did.
(B) Some good comedians have had unhappy childhoods and are unhappy adults.
(C) Most of the best comedians are happy adults.
(D) More good comedians have had unhappy childhoods than have had happy childhoods.
(E) The proportion of comedians who are happy adults is higher than the proportion who are unhappy adults.
这种题确实不少,方法我没总结出来。
不过这类题目好像要求对some-all,can-must要敏感,往往是出题点。
我选A是这样理解的:根据题干,100%的best comedians had unhappy childhoods,但是it is stated that some people who had miserably unhappy childhood ....,所以得出some good comedians have unhappy childhood. 即the proportion must < 100%
