157. Public-sector (government-owned) companies are often unprofitable and a drain on the taxpayer.
Such enterprises should be sold to the private sector, where competition will force them either to be efficient and profitable or else to close.
Which of the following, if true, identifies a flaw in the policy proposed above?
A. The revenue gained from the sale of public-sector companies is likely to be negligible compared to the cost of maintaining them.
B. By buying a public-sector company and then closing the company and selling its assets, a buyer can often make a profit.
C. The services provided by many public-sector companies must be made available to citizens, even when a price that covers costs cannot be charged.
D. Some unprofitable private-sector companies have become profitable after being taken over by the government to prevent their closing.
E. The costs of environmental protection, contributions to social programs, and job-safety measures are the same in the public and private sectors.
这题答案是C
但是我认为C 并没有weak这个policy
就像一个人说把public company卖给private company可以更efficient
但是C说public company的业务是inefficient，这怎么来weak？

除非你题目跟我说让业务变efficient的方式就是关闭不盈利的业务，然后C说不盈利也不能关闭，那我就可以认为C weaken了这个policy，但是原文好像并没有这样说
