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?
After price increases were prohibited, drug manufacturers concentrated on producing new medications to replace existing products.
The population of Voronia rose steadily throughout the period.
Improvements in manufacturing processes enabled drug manufacturers to maintain high profit levels on drugs despite the price freeze.
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.
After price increases were prohibited, some foreign manufacturers of expensive drugs ceased marketing them in Voronia.
这道题目选择的时候也是心慌慌,理论上新药推出定价提高虽然是常识,但是通常不敢选啊。。。
关键还是看其他四个都不好
B是总人数上升和per capita没有必然关系。
C可以使无关也可以是加强政府的成功率,和降低成功率没关系
D也是一个问题
E外国高端药不做这块市场了那应该平均定价下降,而非上升。
