参考答案
正确答案：B
解析："... concrete operational thinkers cannot imagine the steps necessary to complete an algebraic equation, which is too abstract for thinking at this stage." Choice A is not correct because algebra requires formal, not concrete, operational thinking. Choice C is not correct because a child of 10 has reasoning abilities, if they are applied to concrete examples. Choice D is not correct because it is the abstract nature of the steps, not the number of steps, that makes algebra too difficult for a 10-year old.
