Elk now live almost solely in the Rocky Mountains, which would make it seem that elk are mountain dwellers, while they once ranged over virtually all of the continental United States except for a small strip in the extreme Southwest.

1. Elk now live almost solely in the Rocky Mountains, which would make it seem that elk are mountain dwellers, while（which不能指代前面整句话的内容）
2. The fact that elk now live almost solely in the Rocky Mountains would make it seem that they are mountain dwellers, but （正确，用fact指代后面定语从句的内容）
3. It would seem that elk would be mountain dwellers because of their living now solely almost in the Rocky Mountains, but still
4. Now living almost solely in the Rocky Mountains, it would seem that elk were mountain dwellers, although
5. It seems that elk would be mountain dwellers from the fact that they now live solely almost in the Rocky Mountains, since

30-41的答案是选B么? B选项的they are 不会有指代
   Rocky Mountains的歧义么??

我个人选了A..回头看看题越做越晕..都不知道哪个对哪个错了..

如果说A 的which修饰RM还是主句会产生歧义,那么B的they也有指代不明的问题啊...无端加了个the fact这样不wordy么?

还有还有...我突然不明白it又指代了什么了...啊啊越看越糊涂了啊..彻底晕了...请NN们指教啊~~~

感激涕零...

再涕...

GWD30-Q41只能选B

A:which指代Rocky Mountains不对；it指代不清

C:because of their doing 错

D:Now living almost solely in the Rocky Mountains的逻辑主语应该为elk

E:since错，从句子意思来看应该是转折含义

B的The fact would make it seem that 的it 虽然有点不好 但基本不会有歧义

B中的it指代哪个东西？

it做逻辑主语指代后面的内容
