标题: [求助]LSAT逻辑题，想不明白~

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 stataments in the passage are true, which one of the following CANNOT be true?

A. The proportion of good comedians who had unhappy childhoods is greater than the proportion of the best comedians who did.

B. Some good comedias 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.

下午我已经发晕了，牛人帮忙提点一下，我就是想不明白为什么答案是A

看第一句，All of the best comedians have had unhappy childhoods.说明The proportion of best comedians who had unhappy childhoods是100%

good comedians的比例比best comedians还要高，比100%还要高？显然是错了，so cannot be true.
