OG 26.The average normal infant born in the United States weighs between twelve and fourteen pounds at the age of three months.Therefore,if a three-month-old child weights only ten 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 seventeen pounds.

c,it is possible for a normal child to weigh ten 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，但什么是“average weitht gain"呢？d选项又如何翻译？请教高手
