[求助]陈向东归纳63

63.The fire that destroyed the Municipal Building started before dawn this morning, and the last fire fighters did not leave until late this afternoon. No one could have been anywhere in the vicinity of a fire like that one and fail to notice it. Thomas must have seen it, whatever he now says to the contrary. He admits that, as usual, he went from his apartment to the library this morning, and there is no way for him to get from his apartment to the library without going past the Municipal Building.

                             The main conclusion of the argument is that

(A) Thomas was in the vicinity of the fire this morning

(B) Thomas claimed not to have seen the fire

(C) Thomas saw the fire this morning

(D) Thomas went directly from his apartment to the library this morning（C）

(E) Thomas went by the Municipal Building this morning

陈在解释AB时这样写道：因为黎明前是一个很笼统的时间概念，单从此很难判断出T是在火灾发生前还是在火灾发生后经过市政大楼的，所以AB不一定是正确的选项。

大家有没有觉得这样的解释太过牵强，难道正常人会before dawn this morning去library？这么早去，人家门还没开呢，天还没亮呢！我并不是说T一定会在火灾后过去，只是认为B也可以作为答案，因为文中说Thomas must have seen it, whatever he now says to the contrary.那么可以推出B，而且B和C在关于是否看到火灾的事情上意思是差不多的。大家帮忙看看我的理解是否有偏差？
