The results of the company's cost-cutting measures are evident in its profits,which increased five percent during the first three months of this year after it fell over the last two years.

A. which increased five percent during the first three months of this year after it fell

B. which had increased five percent during the first three months of this year after it had fallen

C. which have increased five percent during the first three months of this year after falling over the last two years

D. with a five percent increase during the first three months of this year after falling

E. with a five percent increase during the first three months of this year after having fallen
答案是C，但是但是从时态上看fall应该是过去完成时才对啊，因为FAll发生在increased之前啊，求解释

我觉得啊过去完成时表示一个动作发生在另外一个动作之前。C选项increase的动作用现在完成时是表示过去的动作已经完成并强调结果的影响。而fall这个动作没有一个过去动作的参照，所以不能用过去完成时。

那个increased 难道不是过去的参照么？？？

那不是increased
而是have increased，是现在完成时哦

have increased是指今年前三个月的利润增长已经发生和对现在results of measures are evident的影响,而falling是指利润在过去的两年中一直在下跌

c中 after 用作介词，后面跟动名词形式。不存在时态问题。
after 用作连词后面跟从句才存在时态问题。
