[考題] 請教一題文法

[ikok11 ()]

_______ the most intelligent student in class, Michael was asked to teach his
other fellow students who had lower learning achievement than he did.

1.To be 2.Had been 3.To have been  4.Being


答案是 4

可是 為何不能選 2  後面是 was asked to 是過去式

前面的子句 描述更早 所以用過去完成式 had been

是不是因為 had been 沒有主詞 分詞構句的關係 變成 being 了

懇請高手解答

謝謝
