OG 一道题有疑问 求大神解答

12. 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

疑问：是否可以将rising inventories 看成主语，后接leads ， 也就是B选项 ？  OG解答说主语是inventories，但我觉得主语是rising inventories更合适

elenlothlorien

另外 C选项的解释该如何理解呢？
OG： past tense "were" indicates a completed event, but "can lead" indicates a possibility that continues.
我觉得事态不一致是可以的，过去的事情导致了一种可能性，这没错啊

看modifor里的动词，只能是inventory做accompany的主语，所以主谓一致杀掉BD，C里面they指代有问题，剩下AE，E的用法比A好，所以说选E

请问，为什么只能是inventory做accompany的主语？ 如果去掉中间逗号里面的修饰成分的话：rising inventories can lead to production cutback.  很明显主语是rising inventories ?
