Q39:
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.
为什么是选C呢 如果是不变的 不是说明还是占据了很大的比重么？
我认为C答案应该是错的，正确答案应该是A，比较好理解：
控制烟草后虽然政府收入减少，但用于烟草带来的上的支出也减少，总体来看政府不一定 can't afford the proposed laws
在网上搜了一下其他论坛上的讨论也基本支持这一看法
