请教CR PREP 1-34

34.

     For several years, per capita expenditure on prescription drugs in Voronia rose by fifteen percent or more annually.  In order to curb these dramatic increases, the ministry of health prohibited drug manufacturers from raising any of their products' prices.  Even though use of prescription drugs did not expand after this price freeze, per capita expenditure for prescription drugs continued to increase by a substantial percentage each year.

Which of the following, if true, most helps to explain why the ministry's action did not achieve its goal?

(A) After price increases were prohibited, drug manufacturers concentrated on producing new medications to replace existing products.

(B) The population of Voronia rose steadily throughout the period.

(C) Improvements in manufacturing processes enabled drug manufacturers to maintain high profit levels on drugs despite the price freeze.

(D) In addition to imposing a price freeze, the government encouraged doctors to prescribe generic versions of common drugs instead of the more expensive brand-name versions.

(E) After price increases were prohibited, some foreign manufacturers of expensive drugs ceased marketing them in Voronia.

答案是A,我选B

选项A说在禁止价格上涨后，厂商专心生产新的medication来取代旧的药

但是新的药价格应该也不能上涨吧?

不懂选项A如何解释这个结果

欢迎讨论这一题

觉得A是相对正确的。the ministry of health prohibited drug manufacturers from raising any of their products' prices 通过限制提价。 新品取代旧产品，不在限制范围之内。

B选项，原文没有提及用药人数占总体比例, 总量增加不能解释。

赞同楼上观点。

人口多了，不一定会买药。

A 更好。

这就跟现在市场上买药一样：ABC价格高，治感冒，国家要使控制ABC.

厂家改名CBA, 继续价格高，治感冒。

清楚了，谢谢: )
