18. Tobacco Sales
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

文章说因为政府10%的收入来自烟草,如果政府出台政策限制人们烟草使用,烟草销售减少,那么政府的财政就会有问题.所以政府cannot afford to  institute such laws.

但是烟草造成了越来越多的健康问题(the incidence of smoking-related health problems has risen steadily for the last twenty years).如果这些医疗都是政府赞助的(选项A),那么如果烟草使用的人减少了,虽然政府收入可能减少,但是大家的smoking-related health problems也会减少,政府在医疗上的花销就会减少,那么财政不一定就会有问题啊.所以weaken the argument
