feifei 120题

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?

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

(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 superior
physical fitness

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

原来D选项是不全的，现在补全。另外，答案到底应该是什么呢？下载的详解说是D，但我总觉得怪怪的。

我选的是A

题目的意思： 1，欧洲小孩做操，北美小孩不做操。2，北美小孩比欧洲小孩弱、慢、矮。——结论：做操能使北美小孩更fit

这隐含的假设不是很明显，就是做操对所有小孩都有效么？

完全不理解D有什么相关性。D说做操时欧洲小孩更健康不可缺少的因素。但这又不代表对北美小孩就适用呀。

feifei逻辑题的答案和题都有不完整，甚至错误的地方。大家注意辨别。

注意结论中的only 如果没有only的话 A可以是正确答案

D我也觉得不好 把eu去掉才比较严谨
