2个OG上面的题目，疑惑了在2个点上。 求指点 ，谢谢！！！


1. In a review of 2,000 studies of human behavior that date back to the 1940s, two Swiss psychologists, declaring that since most of the studies had failed to control for such variables as social class and family size, none could be taken seriously.



(A) psychologists, declaring that since most of the studies had failed to control for such variables as social class and family size,



(B) psychologists, declaring that most of the studies failed in not controlling for such variables like social class and family size, and



(C) psychologists declared that since most of the studies, having failed to control for such variables as social class and family size,



(D) psychologists declared that since most of the studies fail in controlling for such variables like social class and family size,



(E) psychologists declared that since most of the studies had failed to control for variables such as social class and family size,

答案能看出来是E，但是C中一个小疑问。
问题：
OG解释C的时候说， The correct form for the sentence's main verb declared'is used here,but having failied is a participial form and as such cannot be themain verb in the clause.
是什么意思？

8. 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



答案也是E



答案也是E

答案也是E

疑问，CD2个选手OG上面说 them有指代 tourist的嫌疑。 但是E就没有这个嫌疑。
搜了网上的帖子，有说，这里E中修饰语中的代词（them）不能修饰另一个修饰语的名词，优先指代句子主语。所以不歧义。
但是D和E 的位置一样啊，都是修饰语中代词吧？？？？!!!为什么E就是没问题？？

解答一：having failied 是做句子的成分 比如插入语 状语 等等不能用作句子中的动词成分

解答二：仔细分析D答案 发现 D的句子中 没有谓语了~~raisng 不能作谓语

不知道有没有说对~~
