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 crystallizingand 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



为什么OG上说C的代词them有指代tourists的嫌疑但是E的代词them却指代清晰 指代chambers呢？
有NN帮忙分析下吗？？

因为C的within them是放在定从里面的，那么这个代词就可能指代定从修饰的那个名词，且them和tourists在书上也一致，容易产生歧义。
E中with them是放在定语之外，则其肯定与定语里的tourists无关，而主语moisture在数上和them不一致，则不可能是moisture。

正确答案是选E吗？

我认为C中开头是一个普通的句子，them有可能指代主语tourists,E中开头exhaled by tourists 只是做定语的成分，而且moisture不可能用them表示，所以就不存在指代不清的问题了，个人见解，说错了不要笑话我哈
