223. (30372-!-item-!-188;#058&005388) (GWD-23-Q23)

After several years of rapid growth, the health care company became one of the largest health care providers in the metropolitan area, while it then proved unable to handle the 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 paying
E. but then proved unable to handle the increase in business, falling months behind in paying

NN们，答案是E，我有两个confusing的地方：
1. While
笔记上说，While在表示转折对比时，有两件events同时发生的含义。
但是，也有正确选项是 while at the same time 的

Q20: PP75.
A recent poll indicates that many people in the United States hold a combination of conservative and liberal political views; i.e., they denounce big government, saying government is doing too much and has become too powerful, while at the same time supporting many specific government programs for health car, education, and environment.

A. they denounce big government, saying government is doing too much and has become too powerful, while at the same time supporting
B. they denounce big government—they say that government is doing too much and has become too powerful—but supporting at the same time
C. they denounce big government, they say that government is doing too much and it has become too powerful, while they support at the same time
D. while they denounce big government, saying that government is doing too much and has become too powerful, at the same time supporting
E. while they are denouncing big government—they say that government is doing too much and it has become too powerful—supporting at the same time

而且，也有while 表示对比但是并不要求是同时发生的情况
所以对于while的用法就很困惑了，希望大家能帮助我

2. V-ing modifier (confusing )
正确选项的结构是：
A became.., but then [ (it) proved unable to do.. , falling behind in..]
v-ing modifier是修饰整个句子，还是修饰前面的but引导的clause?
会不会有产生歧义，既可能修饰前面的clause又可能修饰整句话？

谢谢NN们啦~~~（我是第一次发贴子呢！）
