The spy’s repeated bungling was, above all else, ______ those who wished to thwart her efforts, since it was so unpredictable as to obscure any pattern that might otherwise lead to her capture.  
(A) an obstacle to
(B) a signal to
(C) a hindrance to
(D) an indication for
(E) a snare for
(F) a boon to
答案AC, 我选的是BD。我认为spy她办砸了很多事情，那么对于那些破坏她的人来说一定不是negative的词。所以很困惑，最后一句话到底什么意思。忧伤。。。
