请各位XDJM帮我看看下面()部分中的内容的结构(阅读og 45),and cultural features 和谁平行? reflects 的主语是谁?我实在是看不明白了,谢谢
Though these maps incorporate some information gleaned directly from
Native Americans, rarely has Native American cartography contributed to this official record,which has been compiled, surveyed, and authenticated by non-Native American tribes and their migrations and (cultural features, as well as territoriality and contemporary trust lands, reflects the origins of the data, the mixed purposes for which the maps have been prepared, and changes both in United States government policy and in non-Native Americans’ attitudes toward an understanding of Native Americans.)
