答案是BAB

the effect she had on others was not lost on her audience 具体表达的什么意思？
be lost on 我查的是不起作用 不受影响 也就是说他对别人的影响对观众不是不起作用 是这样么 还是我的理解有错误

读完一遍，应该有种感觉，第一空应该填一个负向词（由于后面的unable），第二空应该填一个正向词。
我是从第三空入手的，前面讲那个comedian怎么样了都没有让他的观众迷惑，这些观众马上纷纷离去，希望他们的行为能产生一个什么，很明显，这里应该填一个正向词，因此符合的只有b。
那么能让观众纷纷离去肯定是comedian不好的事情，所以第一空填B，既然oblivious了，肯定comedian很难察觉discern。第一空的coarse也是负向词，但是第二空没有与之配对的词所以不能选。
整篇大意就是说comedian经常遗忘所以以至于不能察觉到他对于观众的影响这件事（主语从句）并没有让观众迷惑（其实lost on也可以推出第一空的oblivious哈），这些观众纷纷离去，希望他们的行为能传递意义明确的信息。
