这题应该怎么把握？？？

Emily Dickinson’s letters to Susan Huntington Dickinson were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumbering her letters to anyone else.

A.      Dickinson were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumbering

B.      Dickinson were written over a period that begins a few years before Susan’s marriage to Emily’s brother and ended shortly before Emily’s death in 1886, outnumber

C.      Dickinson, written over a period beginning a few years before Susan’s marriage to Emily’s brother and that ends shortly before Emily’s death in 1886 and outnumbering

D.      Dickinson, which were written over a period beginning a few years before Susan’s marriage to Emily’s brother, ending shortly before Emily’s death in 1886, and outnumbering

E.       Dickinson, which were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumber

B. begins时态错，且与ended不平行

C.beginning与ends不平行， 整个句子也没有谓语

D.造成beginning...,ending...,and outnumbering并列的歧义，整个句子没有谓语

剩下的A、E  关键是要把握句子的重心  到底谓语是were还是outnumber

A的一个明显错误是outnumbering的修饰对象不明，容易造成歧义

而E的结构完整无歧义，同时整个句子的重心理解起来也比A更合理
