问题 The author’s primary purpose is______。
The author is most probably leading up to______.

选项 A、a proposal to control medical costs
B、a discussion of new medical treatment
C、an analysis of the cause of inflation in the United States
D、a comparison of hospital and factories

答案A

解析 根据文章末尾两句:“about 75~80 percent of health care expenditures are determined by physicians,not patients。For this reason,economy measures directed at patients or the general public are relatively ineffective.”约有75%~80%的医疗开支是由医生决定的而非由病人决定的。因此,由病人或公共大众制定的经济政策相对而言效率不高。如果还有下文,则文章将会探讨如何针对医生制定经济政策,并提出控制医疗费用的建议。
