这道题做的时候没有一定头绪，还请NN帮忙给看看，思路是什么该怎么取舍？正确答案是C。

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?

A.    The average quantity of tar inhaled by Sandonian smokers who are currently addicted to nicotine will probably not decrease during the next five years.

B.    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.

C.    The annual number of Sandonian smokers developing smoking-related illnesses will probably decrease during the next five years.

D.    The proportion of Sandonians attempting to quit smoking who succeed in that attempt will probably decrease during the next five years.

E.     The number of Sandonians who quit smoking during the next five years will probably exceed the number who quit during the last five years.

那你做这题的思路是什么啊

这题是归纳题，文中说了政府要减少香烟中尼古丁的数量，但是smokers会对尼古丁上瘾，因此本来抽一根烟就可以解瘾的人可能现在要抽两根烟才能抽到同样数量的尼古丁，但是tar的含量不变，所以抽得烟多了，吸入的tar自然就增多了，所以A说吸入的tar的含量不会降低，正好被推理出来了。

个人意见，欢迎指正
