OG(11th)--SC 第8题

8.        Rising inventories,
            when unaccompanied correspondingly
            by increases in sales, can lead to production cutbacks that would hamper economic growth.

(A)         when unaccompanied correspondingly by increases in sales, can lead

(B)         when not accompanied by corresponding

increases in sales, possibly leads

(C)        when they were unaccompanied by

corresponding sales increases, can lead

(D)        if not accompanied by correspondingly increased

sales, possibly leads

(E)         if not accompanied by corresponding increases in sales, can lead

第8题中正确选项E中是不是部分省略了谓语(be动词);另外主语怎么是inventories,而不是Rising inventories?

我的问题在前面的讨论帖中没有,自己顶一下.呵呵
