Medicare, the United Statesgovernment’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.

A.but not with other nonhospital services where 20 percent of the costs must be paid by beneficiaries
B.but not of other nonhospital services, making beneficiaries pay 20 percent of the costs
C.but not of other nonhospital services, for which beneficiaries must pay 20 percent of the costs
D.which is unlike other nonhospital services in that 20 percent of the costs must be paid by beneficiaries
E.which is unlike other nonhospital services that make beneficiaries pay 20 percent of the costs

GWD给的答案是C。我选的是B，因此对于but not of这个结构很明白。
不明白的是后面为什么是for which。
我个人的理解是：Medicare只包括所有的home health care，而不包括非医院服务，整件事情使得受益者还是要承担20%的费用。
我这样的理解有误么？求指教~

for which应该是对前面的解释，表示because的意思
but...., Because beneficiaries must pay 20 percent of the costs

谢谢LZ的解释。
但是for which在这里肯定不是你说的表示because。
“but not of other nonhospital services, for which beneficiaries must pay 20 percent of the costs”。
而是定语从句：pay for是固定搭配，你的解释中pay后面需要的for没有了。beneficiaries must pay for other nonhospital services 20% of the costs.
我的疑问是为什么不能理解为是前面一系列的事情导致受益者要付这些钱呢？
求指教~

很奇怪，如果pay for是一个spilt的话，其他选项都没出出现pay for

我觉的不能making作伴随结果，不是导致吧
