The higher the level of certainvitamins and minerals in the bloodstream, the better a person's lung function,as measured by the amount of air the person can expel in one second.  The lung function of smokers is significantlyworse, on average, than that of nonsmokers. Clearly, therefore, one way for smokers to improve their lung functionis for them to increase their intake of foods that are rich in these helpfulvitamins and minerals.

Which of the following is anassumption on which this argument depends?

(A) Smokers are less likely thannonsmokers to have diets that are rich in vitamins and minerals.

(B) The lung function of smokerswhose diets are rich in those vitamins and minerals is generally better thanthat of nonsmokers with comparable diets.

(C) People whose diets aredeficient in those vitamins and minerals do not typically have other healthproblems in addition to diminished lung function.

(D) Stopping smoking will nottypically improve lung function more than any diet changes can.

(E) Smoking does not introduce intothe body chemicals that prevent the helpful vitamins and minerals from enteringthe bloodstream.

OA：E

我的解题思路：AB 为肯定句，先不看

CDE取非，C：other health problems 无关比较，不选

               D：停止吸烟确实会提高肺功能， 比任何食疗方法都好。属于提出新的措施来削弱，选！

               E：因为选了D就不看了。。。

请大家帮我看一下D，我是不是钻死胡同了。。。多谢啦！

Reading comprehension.

The conclusion is:
One way for smokers to improve their lung functionis is to ask them to increase their intake of foods that are rich in these helpful vitamins and minerals.

D) is wrong because it introduces some new info: diet change. Eating vitamins and minerals does not equal diet change. You can just eat pills!

E), on the other hand, if negated, would make the conclusion fall apart.

Finally, you made a rookie mistake of over-confidence. Read all five choices before deciding which one is the among the possible answers, then make the final decision on which is the best.
