The results of the company's cost-cutting measures are evident in its profits, which increased 5 percent during the first 3 months of this year after it fell over the last two years. (A) which increased 5 percent during the first 3 months of this year after it fell
(B) which had increased 5 percent during the first 3 months of this year after it had fallen
(C) which have increased 5 percent during the first 3 months of this year after falling
(D) with a 5 percent increase during the first 3 months of this year after falling
(E) with a 5 percent increase during the first 3 months of this year after having fallen
想请教下E，after 后面是不是只能跟falling(即动词的现在分词形式)而不能跟助动词having fallen?
A的解释是The verb tenses do not distinguish between the times at which these indicators occurred; the singular it does not agree with the plural profits.是指哪两个动词的先后顺序啊？
还有DE为什么不能用with?

据说after/before having done一般都awkward，因为after/before是有明确的先后关系的，加having done意义何在呢？

A是想说Increase和fall的先后顺序，可是Ron大神说了，这里after 后面用过去时是ok的，OG解释有少数几处错误，此乃其一。A主要错在单复数上
关于with引导的独立主格，我刚查了下，感觉又明白了一点。
看看这个例句：Mobile phones have broken many social taboos, with people answering calls in the middle of a conversation or chatting away on the toilet.
所以with sth/sb doing，这里面的宾语和宾补是有逻辑关系的，比如例句里的people answer call。
回到这题，我之前只是觉得with引导的句子怪怪的，现在终于知道怪在哪儿了。如果是D选项，意思是，with .. increase ... after falling，with后面的宾语是Increase，increase和后面的补充说明不存在逻辑关系，怎么能说increase 又去fall 呢？
