标题: OG12-105 [打印本页] 作者: 半夏之北 时间: 2010-8-25 11:21 标题: OG12-105 105.The average normal infant born in the United States weighs between 12 and 14 pounds at the age of three months. Therefore, if a three-month-old child weighs only 10 pounds, its weight gain has been below the United States average.
Which of the following indicates a flaw in the reasoning above?
(A)Weight is only one measure of normal infant development.
(B)Some three-month-old children weigh as much as 17 pounds.
(C)It is possible for a normal child to weigh 10 pounds at birth.
(D)The phrase "below average" does not necessarily mean insufficient.
(E)Average weight gain is not the same as average weight. 答案是E,明白E对,但是不明白A为什么错 O(∩_∩)O谢谢~~~~作者: judydongxueni 时间: 2010-8-25 12:35
