The fact that elk now live almost solely in the Rocky Mountains would make it seem that they are mountain dwellers, but

Now living almost solely in the Rocky Mountains, it would seem that elk were mountain dwellers, although

E is the key i think

homowing

E应该不行，因为句子前后又明显的转折意思，说Elk now live in the Rocky Mountains这个事实让人家认为elk are mountain dwellers，但是它们曾经在all of the continental United States出现，说明它们不一定是mountain dwellers。所以E用since表原因不行。有人能告诉我B怎么不行啊？

GMAT里面which应该是不可以指代整个句子的，10th的OG有明确的说过。

homowing
