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. Profits 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.

D. Profits 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

A for sure.

和吸烟有关的健康问题稳定上升-->立法缩减香烟的用量
政府垄断香烟销售-->香烟利润占10%的政府收入-->Gandania不能承担法案的提议

关键点在于afford，如果要weaken这个结论，即说明政府可以afford这个法案的，那么减少的这部分收入从哪里来弥补？

那就寻找其他方面削减的开支或者增加的收入。

A选项正确在于，既然health fund是government-funded，减少了烟的使用-->减少health related problems -->减少的health care的支出
