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.

答案是a，how come? why not b??

当然是A啦。

原文的方法说想减少每根烟中的尼古丁的含量来减少与吸烟相关的疾病。又指出已经有烟瘾的人通过多吸几根烟来维持原来原来的尼古丁摄取量。所以，A符号原文的意思，即这个方案对于已上瘾的人没有什么影响。

B用排除法就可以让它出局。文中没有提及未上瘾人的情况。

呵呵，解释精辟

B的意思很离谱的，没法从原文里看出来的嘛

题目里说到的才是答案中会出现的，切忌无由推理

why C is incorrect?

catree

C,这个选项确是错了. 仔细来看问题:

The information above most strongly supports which of the following predictions about the effects of implementing the Sandonian government’s plan?

文中信息支持下面哪个关与S' 计划执行效果的假设.

所以在选项中要找到与原文意思相符的. 原文强调吸烟的人会抽更多的烟, 如果减少尼的含量.

C 中讲的是与抽烟有关的病在5年内会下降, 文中说的是人会抽更多的烟, 所以C 削弱了原文的意思.

我的感受是在读题中,避免加入自己的主观评价. 认为理所应当的行为,正好被出题者抓住了小辩子.

没人问，我来问。为什么D不对呢？

because the article mentions that the addictive people will consume more cigarretes, but does not mentions whether people attemption to give up have more difficulties.

此题看似假设实际类似于conclusion型：The information above most strongly supports which of the following predictions；这种题要求must be true,因此见到无关内容就排除。

B是无法必然推出的，不需要这个PREDICTION也能完成LOR
A 去NOT成削弱——假设题常考方式(注意去掉的not应该是主句中的not)
