After several years of rapid growth, the healthy care company became one of the largest health care provider in the metropolitan area, while it then proved unable to handle to thr increase in business, falling months behind in its payment to doctors and hospitals.

A while it then proved unable to handle the increase in business, falling months behind in its payment to

B while it then proved unable to handle the increase in business and fell months behind in its payment to

C but then it proved unable to handle the increase in business, falling months behind in its paying

D but then proving unable to handle the increase in business, falling months behind in its paying

E but then provED unable to handle the increase in business, falling months behind in its paying

答案选E 我觉得应该选B 实在想不通,请NN们帮帮忙呀

falling months behind in its paying 是做什么结构？跟前面一句的关系是？

请NN解释一下，谢谢！

有点明白了，修饰前面的business，对么？

还有一个问题

one of the largest health care provider：这里面的provider不需要是复数形式么？

你还选b

b明显是错的

falling months behind in its paying不是修饰Business的，它应该是一个伴随状语，逻辑主语是前面的it (just for your reference)

我也觉得provider需要是复数形式，不明白为什么这里是单数
