推理判断题。根据第一段第一句“It began as a game... figured out they could use personal computers to break into telephone company computers and make free, long-distance telephone calls. These young computer talents soon gained the name ‘hackers’”它（也就是黑客）起初是一个游戏：学习计算机的高中生和大学生发现他们可以使用个人电脑闯入电话公司的电脑并拨打免费的长途电话。这些年轻的计算机人才很快就被称为“黑客”。这说明这些高中和大学生是第一批黑客，他们拨打了免费的电话，故选D。
