OG12-6 关于OG解释"them"指代的问题

chaseconsult

6.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 bv
tourists, which raised its humidity to such levels so
that salt from the stone was crystallizing and fungus
was growing on the walls.

[size=undefined]

(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

关于C和D的选项，为何OG解释里说 them 错误的指导tourists 而E选项的them却正确的指代了 chamber  我怎么看起来全部一样呢 NN帮忙解释一下吧~~

对because of moisture that was exhaled by tourists和

because moisture exhaled by tourists有什么区别呢？一个是

because of sth，另一个是because sth ,看起来都是修饰吧，若说

动作的发出，两个都有“exhaled by”有任何差别么？？？？不能体

会，求解，或者求例句

天叉包子

这种解释 在意涵上似乎更容易了解 谢谢

我的问题发了几个小时没人会，看来咱俩是兄弟。
为了不能掩面看你这么悲催，我尝试回答一下。
也就是我做SC的经验。
其实楼主非要较真them 在这里指代不同的话，可以这样理解。
举例：假如ABC是一个层级限制的clause。A包括B，B包括C。若C内有

一个指示代词，恰好，能够指代B或者A的任何一个，那么逻辑上应该

指代——B。因为C是关于B，B关于A。但是C和A并不紧密关联（当然

在正常逻辑下，必有反例，不作为唯一正确与否标志）
回到本题：chamber现状+原因，这两层构成stem。
C：them在which从句中修饰moisture，而moisture是由于tourist发

出的，故优先指代tourist。
D：them是在raising发出的伴随状语中，动作由tourist发出，同样

优先指代tourist。
E：them 在because-clause的主干中，而tourist修饰moisture，但

是them存在范围大于tourist，修饰明显是上一个分句。即使有歧义

也只可能指代chambers or visitors。但是them 在主干中是优先指

代主语的，这是GMAC的逻辑。故E指代正确。
不知so啰嗦，LZ有无了然？
