求助magoosh上的一道题

zysxgz0515UID：3617727

The two writers were of equal talent-indeed Mikhall may have been the more gifted-yet it was his (   ) that led him to switch careers, whereas Dimitri was able to rely on his skills of self-promotion to thrive in a competitive marketplace.
A.naivete
B.persistence
C.diffidence
D.complacency
E. pride
F.timidity
magoosh给的解析选CF，我觉得也对。但不明白为什么不选DE，解析说D意思对，但没有同义选项，难道pride没有自满的意思吗？求大家帮我解答一下，谢谢~~

问题不在于自大骄傲的意思，注意后面的self promotion，一个人自我推销能力强，对比后知道前面的人一定羞怯，所以要选的是诸如胆小的意思。这种6选2，很显然难一点就会有多组同义词，取用哪组，要看上下文。Magoosh的解释牵强，complacency与pride应该认为是同义，不过是干扰项。

magoosh的出题思路很明确，答案都在句子原文找，这题就是要找self-promotion to thrive in a competitive marketplace的反义词，在竞争激烈的市场环境里，必须主动大胆自我推销，反义就是羞涩胆小，只有CF合适
