In late 1997, the chambers inside the pyramid of the Pharaoh Menkaure at Giza were closed to visitors for cleaning and repair due to moisture exhaled by tourists, which raised its humidity to such levels so that salt from the stone was crystallizing and fungus was growing on the walls.
(A) due to moisture exhaled by tourists, which raised its humidity to such levels so that salt from the stone was crystallizing
(B) due to moisture that tourists had exhaled, thereby raising its humidity to such levels that salt from the stone would crystallize
(C) because tourists were exhaling moisture, which had raised the humidity within them to levels such that salt from the stone would crystallize
(D) because of moisture that was exhaled by tourists raising the humidity within them to levels so high as to make the salt from the stone crystallize
(E) because moisture exhaled by tourists had raised the humidity within them to such levels that salt from the stone was crystallizing
题目分析：A用such levels so that，用了such就没必要再用so了，干掉这个选项。B说，thereby raising，停顿一下再让我去琢磨raise这个词汇的发起者，不太好。C前面用were exhaling这种进行时，后面用had raised这个过去完成时，就证明后面的这个事情先发生，而呼出的moisture是后发生的，语意前后反了，逻辑矛盾，干掉。D和E一个用raising一个用过去完成时had raised，我们根据意思可判断出是humidity先升高，之后导致了划线外的were closed to vistor的，应该用过去完成时，选E
