A．add prescription-drugs to the Medicare program
B．allow the Medicare program to provide refunding subsidies to selected medicines to be purchased by Medicare members

答案
参考答案：B
解析：[分析] 细节题型。 答案出自第二段第一行的Congress added prescription-drug coverage to Medicare。 A选项中说的是prescription-drug，而不是prescription-drug coverage；C选项中说的是付钱给“医疗保险制度”，应该是医疗保险制度提供钱给购药的人； D选项的意思是医疗保险制度提供的保险对象是药物，它提供的保险对象应该是购药的人，所以，A、C，D三项均不正确。
