Q21:

Medicare, the United States government’s health insurance program for the elderly and disabled, covers the full cost of home health care, but not with other nonhospital services where 20 percent of the costs must be paid by beneficiaries.

1. but not with other nonhospital services where 20 percent of the costs must be paid by beneficiaries
2. but not of other nonhospital services, making beneficiaries pay 20 percent of the costs
3. but not of other nonhospital services, for which beneficiaries must pay 20 percent of the costs
4. which is unlike other nonhospital services in that 20 percent of the costs must be paid by beneficiaries
5. which is unlike other nonhospital services that make beneficiaries pay 20 percent of the costs

答案选C

B错在哪里?

thx

体会一下意思的不同：
B如下
Medicare,covers the full cost of home health care,but not of other nonhospital services, making beneficiaries pay 20 percent of the costs
逻辑意思是：Medicare涵盖所有home health care费用但不包括非医疗费用，这种安排使得病人要付20%的费用。home health care不用付呀？所以这20%不就是非医疗费用嘛。
如果你认为makingz只修饰other nonhospital services，做定语，会有歧义。他有可能修饰前面整个句子做结果状语。

C如下
Medicare,covers the full cost of home health care,but not of other nonhospital services, for which beneficiaries must pay 20 percent of the costs
逻辑意思是：Medicare涵盖所有home health care费用，但不包括非医疗费用，病人要为非医疗费用付20%的费用

同意楼上的，做题目已经做得昏昏城成了，结果状语明显没有for+原因来的确切

我怎么觉得B选项中的making逻辑主语是句子主语Medicare呢？

我是这样把B选项排除的。

逻辑错误， 不能服务让人。。。。。

我想问的是这个句子结构。。。  but 后面应该是个分句， 可是谓语动词在哪里
