参考答案

正确答案：D
解析：本题属“推理判断题”。作者在本段指出“But those number are not as encouraging as they appearfor lower-income families，because schools are changing their formulas for distributing aid．…they’rethrowing more aid at smarter kids—whether they need it or noL”即学校正在改变的资助发放方案不利于那些低收入家庭，学校把更多的资助给了成绩较好的学生，不管他们是否需要这种资助。也就是说“那些很需要帮助的家庭反而得不到帮助”，故选D。
