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.

再问一题GWD-TN-24-3，不明白为什么要选B。。。
In Rubaria, excellent health care is available to virtually the entire population, whereas very few people in Terland receive adequate medical care. Yet, although the death rate for most diseases is higher in Terland than in Rubaria, the percentage of the male population that dies from prostate cancer is significantly higher in Rubaria than in Terland.
Which of the following, if true, most helps to explain the disparity between the prostate cancer death rate in Rubaria and Terland?

A.    Effective treatment of prostate cancer in its early stages generally requires medical techniques available in Rubaria but not in Terland.
B.    Most men who have prostate cancer are older than the average life expectancy for male inhabitants of Terland.
C.    Being in poor general health does not increase one’s risk of developing prostate cancer.
D.    It is possible to decrease one’s risk of getting prostate cancer by eating certain kinds of foods, and such foods are more readily available in Rubaria than in Terland.
E.    Among men in Rubaria, the death rate from prostate cancer is significantly higher for those who do not take full advantage of Rubaria’s health care system than for those who do.

第二题说R比T的医疗条件好  但是死于prostate cancer 的 男性，R比T高

B说了患者的患病年龄比T的人均预期寿命还长，就是T大多数人还没活到得病的年龄就死啦~所以T死于cancer的人呢就少咯
