75.
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
求助： 个人觉得A选项中denounce与support应该是平行结构，但为何后者用ing形式呢？即便按照讨论贴中二楼的解释主语一致时可以省略的话，那也应该是while at the same time support 吧？请NN赐教，谢谢！
