PREP-2-146！！！

The gyrfalcon, an Arctic bird of prey, has survived a close brush with extinction; its numbers are now five times greater than when the use of DDT was sharply restricted in the early 1970's.  

(A) extinction; its numbers are now five times greater than

(B) extinction; its numbers are now five times more than

(C) extinction, their numbers now fivefold what they were

(D) extinction, now with fivefold the numbers they had

(E) extinction, now with numbers five times greater than

 解释说DE中 now with...部分错误修饰主语gyrfalcon.

本来应该修饰什么呢？还有now with部分，在DE是做什么成分，独立主格吗？

本来应该修饰什么呢？还有now with部分，在DE是做什么成分，独立主格吗？

应该都不是做独立主格成分，D连形式都不是。 DE都是随伴随修饰主句

我比较不明白的是numbers是做什么意思？ 数量吗，那应该是number才对啊

The number of ...is greater than....
