During the nineteenth century Emily Eden and Fanny Parks journeyed throughout India, sketching and keeping journals forming the basis of news reports about the princely states where they had visited.

(A) forming the basis of news reports about the princely states where they had

(B) that were forming the basis of news reports about the princely states

(C) to form the basis of news reports about the princely states which they have

(D) which had formed the basis of news reports about the princely states where they had

(E) that formed the basis of news reports about the princely states they

请教AE的差异；A had visited表示visit发生在form the basis之前不行吗？

A 的错误主要有两处:1 forming错.现在分词表示持续进行的动作

2.where错,应该使用that.

C 如果不看have的时态问题，请问用which是不是也有问题？

现在对which的用法还很不够理解...

觉得还是E好

个人感觉顺口多了
