B.       due to moisture thattourists had exhaled, thereby raising its humidity to such levels that saltfrom the stone would crystallize
C.     because tourists wereexhaling moisture, which had raised the humidity within them to levels suchthat salt from the stone would crystallize
D.     because of moisture thatwas exhaled by tourists raising the humidity within them to levels so high asto make the salt from the stone crystallize

A项中to such level so that 在OG中没有指出这是错误的，难道这样用时正确的？
我怎么觉得是wordy啊。
请指教，谢谢

OG 是不是有时并不是把所有错误都指出来啊？
就像A中which也是很明显的错误，可是它就没有指出？
小小疑惑中，盼解答~！

我还有一个问题。。。
C选项中OG说them指代tourists，所以不对 D选项中them也是指代tourists
而在E选项中them就是指代Chambers，为什么？之间有什么玄机吗？非常不明白E.       because moisture exhaled by tourists had raised the humidity within them to such levels that salt from the stone was crystallizing

哎！必须感叹一句，之前做了好几遍OG，都是看选项有点不对就排除了，这样做题时能做对，可是等我今天开始打算研究一下OG的解释时，才发现里面问题真不少。。OG必须要好好研究啊，平时做这题1分钟左右，这下子研究OG解释加费解就用了半个多小时了，其实OG还真是很有料，太忽视了！！

C： 对于them而言，tourists相当于主句主语。这没什么好说的。肯定优先

D:  because of是介词。整个后半段与主句主语联系不密切。that引导从句修饰moisture。与整个句子的主语chambers距离就更远了。them所在句子中，tourists是中心词（游客呼出湿气 增加了湿度）。them与游客的关系更加紧密。

E：because引导原因状语从句，修饰主句谓语。与主句关系紧密。（内室关闭 是因为 湿气增加了 湿度within them）另一方面，tourists所在短语充当修饰语修饰moisture，优先级很低。them指代全句主语chambers。
