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?

Some teachers give as homework assignments work of a kind that research suggests is most effective educationally when done in class. 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. Some homework assignments are related to free-time activities that children engage in, such as reading or hobbies. 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. Some free-time activities teach children skills or information that they later find useful in their schoolwork.

题干翻译
一些社论主张限制12岁以下儿童的家庭作业。他们指出，自由时间活动在儿童发展中很重要，大量家庭作业会严重限制自由时间，阻碍发展。但12岁以下儿童实际平均家庭作业时间每晚仅略多于30分钟，留有大量自由时间。因此，实际上社论的理由不能证明他们所主张的限制是合理的。 逻辑链

削弱题 推理过程
教育理论家根据12岁以下儿童平均家庭作业时间不多，得出无需限制家庭作业的结论。要削弱此结论，需找到能表明即使平均时间不多，但仍有理由限制家庭作业的选项。 选项分析
A选项：一些老师布置的家庭作业类型在课堂上完成教育效果最佳。但这与是否需要限制家庭作业总量无关，不能削弱，排除。 B选项：对于12岁以下儿童，早期定期做作业虽无已证实的学术价值，但很多教育者认为能培养自律和时间管理能力。这是在说做作业的好处，是对不需要限制的加强，而非削弱，排除。 C选项：一些家庭作业与儿童的自由时间活动相关，如阅读或爱好。这与是否需要限制家庭作业量没有直接联系，无法削弱，排除。 D选项：相当比例的12岁以下学童，尤其是低年级的，每晚布置的家庭作业不到10分钟。这意味着存在部分儿童家庭作业时间极少，那么平均30分钟可能掩盖了另一部分儿童家庭作业时间过长的情况，也就说明可能还是有必要限制家庭作业，有力地削弱了结论，当选。 E选项：一些自由时间活动能教给儿童在学业中有用的技能或信息。这与是否要限制家庭作业无关，不能削弱，排除。
