问题 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 B6 supplements or eat a diet that contains more B6 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?

选项 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、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.

答案D

解析 本题让我们评价“老年人要想获得所需的B6的量,一定要摄入B6以做补充或吃比他们年轻时代吃的含B6更多的食物。(D)选项可以作为一个很好的评价。因为我们回答了“yes”,那么老年人可能不需额外补充B6;如果回答“no”,则老年人需吃B6以做补充或吃比年轻时吃的含B6更多的食物,因此上述推理正确,所以(D)正确。
