(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

麻烦看下BC 阿 只看begins ended能直接判断错了吗。答案说 The verbs describing the letter-writing period (begins and ended) are not parallel.

BC当然看到这两个是错的，开始和结束都发生在over a period这个时间范围里面，那么时态都要相同才行

只有当作者明确要表达两个发生在不同时间段的动作时，时态才需要改变
