标题: GWD3-Q31 [打印本页] 作者: rainbowmanutd 时间: 2011-7-14 13:04 标题: GWD3-Q31 Although most smoking-related illnesses are caused by inhaling the tar in tobacco smoke, it is addiction to nicotine that prevents most smokers from quitting. In an effort to decrease the incidence of smoking-related illnesses, lawmakers in Sandonia plan to reduce the average quantity of nicotine per cigarette by half over the next five years. Unfortunately, smokers who are already addicted to nicotine tend to react to such reductions by smoking correspondingly more cigarettes.
The information above most strongly supports which of the following predictions about the effects of implementing the Sandonian government’s plan?
The average quantity of tar inhaled by Sandonian smokers who are currently addicted to nicotine will probably not decrease during the next five years.
Sandonian smokers who are not already addicted to nicotine will probably also begin to smoke more cigarettes during the next five years than they had previously.
The annual number of Sandonian smokers developing smoking-related illnesses will probably decrease during the next five years.
The proportion of Sandonians attempting to quit smoking who succeed in that attempt will probably decrease during the next five years.
The number of Sandonians who quit smoking during the next five years will probably exceed the number who quit during the last five years.
Conclusion: question premises:1) addiction to nichotine prevents ppl from quitting 2) govt reduces nichotine by half over the next 5 years in order to decrease desease 3) BUT, ppl already addicted to nichotine tend to smoke more
哪一个answer是可以被遇见的。 A) 肯定没问题啦。。。。 B) 不关non-addicted 什么事儿 C) premises里没说管不管用。。 D) premises里面没说关于戒烟成功啊。。。。 E) 无关作者: ranger62 时间: 2011-9-29 11:20
首先D肯定是错的，因为比例实际上是提高了。因为nicotine降低，那么不上瘾的人会增加，所以成功戒烟的比例肯定会上升。
