[求助]Princeton的一道题

An attempt
                    to ratify the Equal Rights Amendment, begun almost two decades ago, has unsuccessful despite efforts by many important groups, including the National Organization for women.

A to ratify the Equal Rights Amendment, begun almost two decades ago

E that has begun almost two decades ago to ratify the Equal Right Amendment

答案是A,我选的E,想问一下，这里用的begun是说attempt 是被动啰？那么attempt自己不能begin么？

请大家教一下！

谢谢

begin可以用被动啊

i began this project a couple of days ago

this project was begun by me a couple of days ago.

当然begun做被动有点狼狈。。。
