equivalent to the enrollment of
the equivalent of those enrolled in
equal to those who are enrolled in
as many as the enrollment of
as many as are enrolled in
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
一点个人看法，句意想说的，重点不在于<得到在职培训的800万人刚好等于(equal)大学入学的人数>，而是想要说 <得到在职培训的人 和 上大学的人 一样多>，
强调的是这个多，数量级的相近。
所以 as many as 要优于所有用 equal 的表达。
在这道题目中 as many as ， 是把people和 后面的 people who are enrolled in 做比较， 但是为什么可以省略这么多成分
感觉b更合适，求高人指点
