From the last paragraph we know that ______.
A．forgetfulness is a response to learning
B．the memory storage system is an exactly balanced input-output system
C．memory is a compensation for forgetting
D．the capacity of a memory storage system is limited because forgetting occurs请帮忙给出正确答案和分析，谢谢！
参考答案
正确答案：A
解析：推理判断题。最后一段第二、三两句指出，学习与忘却之间不断地进行调节，忘却率与学习的多少也有关联，由此可以推断出，忘却是对学习的一种反应。B选项说法过于绝对，记忆是个输入输出平衡系统只是当代的一种模型。C和D的内容都在文中找不出推理的依据。
