雪落无声

All actors are exuberant people and all exuberant people are extroverts.but nevertheless it is true that some shy people are actors.

if the statements above are true ,each of the following must also be true EXCEPT;
a.some shy people are extroverts
b.some shy extroverts are not actors
c.some exuberant people who are actors are shy
d.all people who are not extroverts are not actors
e.some extroverts are shy

看到这类有ALL，SOME，WITHOUT，ONLY 词的题目就搞得一团糨糊了，理不出个头绪来。

这种类型的题目建议你画一下韦氏图 各个关系一目了然 一定不会错

另外 如果实在搞不懂 GMAT对这种逻辑关系不作要求 考试不会考到 尽管放心 这是LSAT的要求
