120. In Europe, schoolchildren devote time during each school day to calisthenics. North American schools rarely offer a daily calisthenics program. Tests prove that North America children are weaker, slower, and shorter-winded than European children. We must conclude that North American children can be made physically fit only if they participate in school calisthenics on a daily basis.

Which one of the following is assumed in the passage?

B.        All children can be made equally physically fit by daily calisthenics.

C.        Superior physical fitness produces superior health.

D.       School calisthenics are an in indispensable factor in European children’s

E.        North American children can learn to eat a more nutritious diet as well as to exercise daily.

A选项：所有孩子通过C身体都能变好。表述了同质性。（因为C不一定适合美国孩子)

为什么选D啊？
