题目分析：
略。

选项分析：

A选项：应将介词with改成of，这是因为，在逻辑上平行的两者是home health care和 other nonhospital services，因此两者应该保证平行，都由介词of引导出来。

B选项：现在分词短语making beneficiaries pay 20 percent of the costs做other non-hospital services的定语。这导致，other non-hospital services主动发出make beneficiaries pay 20 percent of the costs这个动作。在逻辑上，其它的非医院服务不能“使得”受益者付钱，只能让受益者在这些服务中付钱。

C选项：Correct. 本选项在语法和逻辑上均是正确的。

D选项：which is unlike other non hospital services是一个非限制性定语从句，其先行词为home health care。这个定语从句没有问题，问题出现在定语从句身后由连词in that引导的原因状语从句中。在逻辑上，“受益者需要再花20%的成本”和“家庭医疗同非医院服务不相同”这两句话之间没有因果关系。

E选项：other non-hospital services不能主动发出make beneficiaries pay 20 percent of the costs这个动作错误同选项(B)。
