OG12 SC 6中的指代问题

请教牛牛们：OG12-SC6的答案讲解中，说C和D中的them指代不清，指代的是tourists,那么为什么E中的them不会也让人误认为是指tourists？多谢！

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

尝试着解答一下，我们说的代词指代一般是优先指代主句的主语，Topway的them指代不清楚因为within chambers 和within tourists从用法上都可以，并且这个tourists都在CD中担任成分C中主语，D中动作发出者


而在E中这个tourists 是moisture修饰语里面的，所以后面的them肯定不会指代tourists的

那请问， D，中 moisture that was exhaled by tourists ， that was exhaled by tourists 定语从句，不也是 修饰 moisture的么？

主语位置的代词指代具有倾向性。
看og的分析，也可以得出一样的结论。选项当中的provisions不是主语，而they却在主语位置。因此应指代和语法上指代的不一致，导致ambiguous。
