不会啊,就是因为有了eventually和over the last few years,题目才对的.
题干中有个假设 N年以后毕业的人数=N年以后进入job market的人数
假设哈佛的课程是1年可以毕业的,入取了 100人,那么一年以后, 就有100个人进入 人才市场, 即100个人/每年,那么连续4年, 总共400个人进入job marker. 但是美国经济衰退,人才市场一下子不需要那么多的人,但是入取了400个人,所以就控制供应量,拉长课程时间,变为4年, 前面3年,人才市场的供应量为0,0,0.到了第四年,400人,但是平均一下, 也是100人/每年,并没有在over the last few years增加人数.
