问一道真题(取自GMAT30回)

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-founded.

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 Gandania government.

E)No government official in Gandania has ever previously proposed laws aimed at curtailing tobacco use.

正确答案: A

实在想不出来为什么A是攸关选项又是正解耶…

求助!!!

因为医疗机构是goverment-founded，所以虽然政府在烟草上赚钱，但医疗方面支出增加了

In Gandania, where the government has a monopoly on tobacco sales.也就是说，收入是政府的，并且占其利润的10%。如果 a series of laws aimed at curtailing tobacco use in Gandania，那么随着销售的下降，政府的烟草销售收入下降。但是，烟草销售下降，抽烟的人少了，the incidence of smoking-related health problems has decrease,而如果如A)All health care in Gandania is government-founded，那么医疗支出也会减少。

所以，削弱结论Therefore, Gandania cannot afford to institute the proposed laws.

Soga…谢谢楼上,讲解的很清楚

只是,这个答案似乎需要一点点想像力

文中没有提到任何关于＂医疗机构须负担医疗费用＂呀,

只说因为越来越多抽烟导致的健康问题,故此law的目的是想减少增加的健康问题,(或许只是基于关心人民身体健康)…那么即使是由政府创办也是基于政府关心人民啊…??

很笨的问

欧觉得，要是问题改成assumption，是不是A就好理解了？
