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
题目分析：主语是inventories，谓语用单数肯定不合适，我们先把B和D干掉。
C中那个they were很多余，前面都说rising inventories了，再加一个they多余，干掉C。
A和E进行比较，一个用when一个用if，在意思上差别还是比较明显的，
A强调inventories当在某个时间段能导致一个什么结果，
E强调的是inventories在什么条件下能导致什么结果，显然E读起来更舒服。选E。
