[求助][原创]1个Prinston 语法题，很是迷惑

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

A. the same

B. begun almost two decades ago, for ratifying the Equal Rights Amendment

C.begun for ratifying the Equal Rights Amendment almost two decades ago

D. at ratifying the Equal Rights Amendment, begun almost two decades ago

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

OA是A, 但是A中那个begun不对呀！偶选的E.

begun是过去分词做定语修饰an attempt(an attempt后面接的是介词短语可以跳过，而且begun逻辑上不会修饰Amendment)挺合理啊..

E里面应该用过去时跟ago搭配,另外attempt to do sth.是固定搭配，中间不能插别的东西.
