Educational Theorist: Recent editorials have called for limits on the amount of homework assigned to schoolchildren younger than 12. They point out that free-time activities play an important role in childhood development and that homework in large quantities can severely restrict children's free time, hindering their development. But the actual average homework time for children under 12 little more than 30 minutes per night-leaves plenty of free time. In reality, therefore, the editorials' rationale cannot justify the restriction they advocate.
Which of the following, if true, would most seriously call into question the educational theorist's conclusion?

A. Some teachers give as homework assignments work of a kind that research suggests is most effective educationally when done in class.

B. For children younger than 12, regularly doing homework in the first years of school has no proven academic value, but many educators believe that it fosters self-discipline and time management.

C. Some homework assignments are related to free-time activities that children engage in, such as reading or hobbies.

D. A substantial proportion of schoolchildren under 12, particularly those in their first few years of school, have less than 10 minutes of homework assigned per night.

E. Some free-time activities teach children skills or information that they later find useful in their schoolwork.

选项D，大多数12岁以下，作业时间小于10分钟，不应该是支持educational theorist 的结论吗（不应该限制）？？？

大多数小孩时间小于10min，所有小孩平均30min，说明有一部分小孩时间明显大于30min。只能这样理解，除了D之 ...

哇 谢谢！想了二十分钟也没想明白  这真的是在考逻辑...

这种题出现在考试能做正确还是比较困难的。
conclusion的evidence主要是homework 30min，所以看所有选项里和时间有关的只有C,D。 但是C其实是加强结论的。
这道题关键是要识别substantial，LS说的对，平均如果30min，大量的10min，肯定有exterme case是远大于30min。
