1. 当初我做这个的时候也选C 但是想想,drug’s maker charges 的是price么？明显不合逻辑阿，但这里要一个名词，charge的宾语，我还是觉得D最合适

2 翻译一下是   经过几年的快速增长， healthy care company 成为了几家最大的health care providers in the metropolitan area，但是 随后证明了它没有能力处理增长的业务，把给doctors and hospitals的payment 给拖了几个月了。

ABC应该都是 it was proved   后面问题也多多   D不能是proving 应为主语是company    falling是分词表结果

恩，谢谢一层牛牛的翻译！！！豁然开朗啊！
