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

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

这道题选C，我想问一下，after后面的句子，over the last two years能用falling么？我觉得应该是完成时，所以选了E，请教一下，为什么是falling 呢？

我是说应该用完成时啊？

 over the last two years不是一个完成时的标志么？

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 时态不对，应该用现在完成式。
B. which had increased five percent during the first three months of this year after it had fallen 时态不对，不应该用现在完成式
C. which
                have increased five percent during the first three months of this year after falling 用which修饰明确，时态正确
D. with a five percent increase during the first three months of this year after falling 修饰the results 不正确
E. with a five percent increase during the first three months of this year after having fallen  修饰the results 不正确

但看了大家的解释，还是对为什么不能使用after having fallen不是很清楚，请nn再解释下两者区别好么？

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.

同一句子中，相同代词it指代同一个东西，第一个指代company，第二个指代profit，不对。而且profits是复数，不能用it指代                                                                                                                                                                        

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

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