请教一道题目---标题要变长---------

The higher the level of certain vitamins 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 significantly worse, on average, than that of nonsmokers.  Clearly, therefore, one way for smokers to improve their lung function is for them to increase their intake of foods that are rich in these helpful vitamins and minerals.


Which of the following is an assumption on which this argument depends?


(A) Smokers are less likely than nonsmokers to have diets that are rich in vitamins and minerals.
(B) The lung function of smokers whose diets are rich in those vitamins and minerals is generally better than that of nonsmokers with comparable diets.
(C) People whose diets are deficient in those vitamins and minerals do not typically have other health problems in addition to diminished lung function.
(D) Stopping smoking will not typically improve lung function more than any diet changes can.
(E) Smoking does not introduce into the body chemicals that prevent the helpful vitamins and minerals from entering the bloodstream.


选项E 看不懂什么意思啊，INTRODUCE INTO 的到底是什么东西啊，是吸烟产生的物质，还是维他命啊？

introduce into 应该是倒装句
introduce X into Y 到装成 introduce into YX
就像bring to 达到装一样

D也是纠结了我半天，最后觉得这个是目标和方案的问题，

目标是  增强抽烟者的肺功能
方案是  增加含有维他命事物的摄入
要加强方案能达到目标

D 的话涉及到一个新的方案 戒烟 ，应该是无关吧
就算是两个方案对比的话，说戒烟不比改善饮食更好，那也就是说两者差不多？有点削弱的意思吧

E 就是直接说抽烟不影响维他命的摄入，即是  方案是有效的

3楼的倒装正解，LZ参考一下。（倒装是因为chemical后面的修饰语太长，因此如果放在to前面，就很突兀）

introduce into 应该是倒装句
introduce X into Y 到装成 introduce into YX
就像bring to 达到装一样
bring X toY 倒装成 bring to YX
smoking does not introduce chemicals(that...) into the body
是正常顺序的句子
想问个问题 噶
在纠结D 如果不抽烟能解决问题 根本就不需要这种diet了啊

E的意思是说：吸烟不会带进身体一些化学物质（这些物质可能是烟本身有的，也有可能是吸烟后在身体内产生化学反应得到的，反正就是因为吸烟进入身体的），这些化学物质会阻止维他命和矿物质的吸收。
