急问:四月SC机经中的一题

1.For many revisionist historians, Christopher Columbus has come to personify devastation and enslavement in the name of progress that has decimated native peoples of the Western Hemisphere.（nlhsz提供）

A. devastation and enslavement in the name of progress that has decimated native peoples of the Western Hemisphere
B. devastation and enslavement in the name of progress by which native peoples of the Western Hemisphere decimated
C. devastating and enslaving in the name of progress those native peoples of the Western Hemisphere which in the name of progress are decimated.
D. devastating and enslaving those native peoples of the western Hemisphere which in the name of progress are decimated.
E. the devastation and enslavement in the name of progress that have decimated the native peoples of the Western Hemisphere.

我觉得that 从句应该修饰 the devastation and enslavement, 因为是devastation 和 enslavement 屠杀了西半球的土著人，所以用have decimated。另外前后都加了定冠词，更有所指，所以我想选E

devastation and enslavement 和decimate有没有同意重复之嫌呢？

另外，我也想知道以前讨论的链接在哪里，可以帮忙找一下么，谢了谢了
