请各位帮忙解答英语几道填空题吧

A.preparation...passionate
B.artfulness...disengaged
C.dabbling...superficial
D.caprise...considered
E.indecision...lightheared
答案选的C,不过后面半句话已经说了这个人的作品很impressive,为什么第二个空还选superficial啊,这不是矛盾了么?

2.MacCrory's conversation was_____:she could never tell a story,chiefly because she always forgot it, and she was never guity of a witticism, unless by accident.
A.scintillating
B.unambiguous
C.perspicuous
D.stultifying

答案选的A,不过我想知道这句话怎么理解,never tell a story而且又always forgot,这不是说明这个人表达能力不好么,怎么后面又跟一句witticism?
麻烦解释一下.我不懂这句话的意思啊.
