单项选择题

As people age, the number of calories they need each day decreases while their daily requirement of vitamin B6 increases. Clearly, unless older people take 136 supplements or eat a diet that contains more 136 than did the diet they ate when they were young adults, there is little likelihood that they will get B6 in needed amounts.
Which of the following would be most helpful to know to evaluate the argument

A．Whether the relative decrease in the daily requirement of calories is greater than the relative increase in the daily requirement of vitamin B6.

B．Whether the form of vitamin B6 found in dietary supplements is more readily absorbed and utilized by the body than is the from of this vitamin that is found in food.

C．Whether the consequences of not getting vitamin B6 in required daily amounts are more serious for older people than for young adults.

D．Whether the diets of most people, when they are young adults, include vitamin B6 in amounts far in excess of their daily needs.

E．(E) Whether the diets of older people are more likely than those of young adults to include one or more meals a day that are devoid of foods containing vitamin B6.
