86. The results of the company’s cost-cutting measures
are evident in its profi ts, which increased 5 percent
during the fi rst 3 months of this year after it fell over
the last two years.
(A) which increased 5 percent during the fi rst
3 months of this year after it fell
(B) which had increased 5 percent during the fi rst
3 months of this year after it had fallen
(C) which have increased 5 percent during the fi rst
3 months of this year after falling
(D) with a 5 percent increase during the fi rst
3 months of this year after falling
(E) with a 5 percent increase during the fi rst
3 months of this year after having fallen

答案是C. 不明白“have increased 5 percent during ”和“after falling”这两个时态的选用。 谢谢！

search好像也不是个容易的事情，我刚好也遇见这个问题，分享下：GMAT的语法严谨，这里主要是考察多个动作发生的先后或者逻辑关系。考点是，increase和fall之间的先后，明显fall先发生，increase后发生，因此a没有体现出来。当然从做题的角度讲，有个“it”帮助筛选答案，which引导的从句中主语应该是承接前面profits（复数），所以有it的都不合适

 自己解释之后都觉得又有点心虚了，在google上搜了下，发现某个人的答案我比较欣赏：1）全句的时态应该是现在时（和主句一致）2）如果用with的话，不能表示增加的5%的profit都是由cost cut导致的，有可能只是5%的一部分。原文如下........profits, with a five percent increase ....' : This can be interpreted as profits with a five percent increase (in sales or in population or might be anything). D/E does not associate ' a five percent increase' with 'its profits' clearly.

按照OG的解释：
“The sentence therefore needs to clarify the sequence by presenting the first-identified indicator in a clause with a verb tense that indicates a later time period than the verb tense in the clause presenting the second-identified indicator. ”
也就是说：“上升5 percent”的现在完成时have increased  晚于 “持续走低”的现在进行时falling。
也就是说OG的意思是：现在完成时 晚于 现在进行时
这个逻辑我怎么都想不明白。。。。
高手救命啊～～～～～

同问！这个题同时是GWD24的第8题，论坛上有很多关于这道题的讨论，但是我看了几乎所有的帖子，都没有能解释这个问题的。。。。
