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.
为什么A对。题目不是说the ministry of health prohibited drug manufacturers from raising any of their products' prices。 都已经禁止提高制造商任何产品的价格，那么再生产出的新药不是也包括在制造商生产任何的产品中吗？
政府限制的是在原来的价格基础上提价。制造商开发新药的话直接就定一个很高的价格，发行价就很高，根本不用提价。这并不会被政府的规定所限制。
