In Europe, schoolchildren devote time during each school day to calisthenics. North American schools rarely offer a daily calisthenics program. Tests prove that North American 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?

A. All children can be made physically fit by daily calisthenics.

superior physical fitness.
