做PREP遇到的逻辑题~求思路~

陌下清风

For several years, per capital expenditure on prescription drugs in Voronia rose by fifteen
percent or more annully. 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 ture, most helps to explain why the ministry's action did not achieve
its goal?
1.After price increases were prohibited, drug manufactuers concentrated on producing new
medications to replace existing products.
2.The popution of Voronia rose steadily throughout the period.
3.Improvements in manufacturing processes enabled drug manufacturers to maintain high
profit levers on drugs despite the price freeze.
4.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.
5. After price increases were prohibited , some foreign manufacturers of expensive drugs
ceased marketing them in Voronia.


答案我记不太清了，好像是选A吧，但是我没搞清制造商生产别的药与价格上升有什么关系....还望点拨~~
像第三个，第五个这种选项为什么不对呢...谢谢大家了~~

这个可以把v国看成我国，有最高限价的药都不容易买到，因为药房利润低。厂家转而生产相似成分的新的产品，然后涨价。比如前几天闹腾的维c银翘片就是因为太便宜了，所以被利益集团打压，让大家去买贵的利润高的药

楼上说的很明白，既旧药被限制价格导致药厂去生产贵的新药
