求助GWD23 39这道题的解题思路是怎样的？

In Gandania, where the government has a monopoly on tobacco sales, the incidence of smoking-related health problems has risen steadily for the last twenty years.  The health secretary recently proposed a series of laws aimed at curtailing tobacco use in Gandania.  rofits from tobacco sales, however, account for ten percent of Gandania’s annual revenues.  Therefore, Gandania cannot afford to institute the proposed laws.
Which of the following, if true, most seriously weakens the argument?

A：All health care in Gandania is government-funded.
B:Implementing the proposed laws is not likely to cause a significant increase in the amount of tobacco Gandania exports.
C:The percentage of revenue Gandania receives from tobacco sales has remained steady in recent years.
Drofits from tobacco sales far surpass any other single source of revenue for the Gandanian government.
E:No government official in Gandania has ever previously proposed laws aimed at curtailing tobacco use.


解这道题的时候我的思路是寻找结论中focus的东西及结论的特殊性和具体性，结论中说明烟草的销售提供了政府的很大一部分收入，所以政府没能力减少烟草销售，我想这里focus的应该是与烟草收入与政府收入得关系，以及改变带来的影响，但是在选项中选择的MS没有方向符合又与结论有联系的，要不就是没作用要不就是无关选项，最后随意选了C，但答案是A，后来看解释确实C是加强，A也是唯一符合要求的选项，但是A中暗含了政府卖烟的钱用来给人治病，还不如不卖这样的意思，考试很难体会着一层的意思怎么办，而且A项抛出一个health care的概念与结论的联系不是很紧密所以下意识就排除了，考试中遇见这样的类似的选项而且是很长的第一时间不能体会出与结论之间联系的的选项怎么办，能有好的方法吗？

希望NN来帮解答下~~这道题我觉得没什么思路，就是阅读的难度，体会选项与结论的关系，A如果读懂了很好解答，没读懂就直接把他当无关给kill掉了，但是考场上如果碰见长选项我觉得我第一时间很难体会出来的。。。

Answer (A) seems to be a ball out of left field. But if you read the stimulus with a critical eye, you would remember that only three things were mentioned: tobacco, health problem, and the government. The reason why the government hesitates to curtail tobacco sales is purely money-related since the tobacco industry provides revenue to the government.  One way to pursuade the government to change its policy is to show that tobacco also causes the government money. (A) fits the bill.
