参考答案
正确答案：D
解析：答案依据第三段第三、四句：As time goes on, however, we shall have to use our brains more and more, and eventually we shall need larger ones. This is likely to bring about a physical change to the head, in particular the forehead, which will grow larger，“随着时间的推移，我们用脑越来越多，最终我们将会需要更大的脑容量。这很可能会给头部带来变化，尤其是前额，它会变得更大。”所以D为正确选项。
