Argument says that smokers have to increase their intake of vitamins and minerals.
That means the current one is not sufficient
We are not concerned about what is the current diet level. We just want to prove that eating more vitamins will help smokers improve the lung function.
what if smoking blocks absorption into bloodstream. In this case, however much the person increases intake of vitamins, his lungs won't improve.
because the vitamins are never absorbed.
This destroys the argument.
Therefore, E is the correct answer choice. It says that smoking does not prevent vitamins from entering the bloodstream. So if the non-smokers increase their intake of vitamins then their lung function will improve.
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.ISNT THIS ALSO AN ASSUMPTION??? ARENT WE ASSUMING THAT THE SMOKERS DONT ALREADY HAVE DIET 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. WHAT IS WRONG WITH THIS??
(D) Stopping smoking will not typically improve lung function more than any diet changes can.WE NEGLECT THIS BECAUSE THIS OPTION IS TESTING OUR COMMON KNOWLEDGE RIGHT?
(E) Smoking does not introduce into the body chemicals that prevent the helpful vitamins and minerals from entering the bloodstream. I AM FINDING ALL CORRECT EXCEPT 1... E DIDNT SEEM THE 'BEST' CHOICE TO ME
