一道超郁闷的阅读主旨题 文章不长 求哪位高手指点一下 谢了

lllmmm

Maps made by non-Native Americans to depict Native American land tenure, resources, and population distributions appeared almost as early as Europeans' first encounters with Native Americans and took many forms:  missionaries' field sketches, explorers' drawings, and surveyors' maps, as well as maps rendered in connection with treaties involving land transfers. Most existing maps of Native American lands are reconstructions that are based largely on archaeology, oral reports, and evidence gathered from observers' accounts in letters, diaries, and official reports; accordingly, the accuracy of these maps is especially dependent on the mapmakers' own interpretive abilities.

Many existing maps also reflect the 150-year role of the Bureau of Indian Affairs (BIA) in administering tribal lands. 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 Americans.  Thus our current cartographic record relating to 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.

Which of the following best describes the content of the passage?   D

(A) A chronology of the development of different methods for mapping Native American lands
(B) A discussion of how the mapmaking techniques of Native Americans differed from those of Europeans
(C) An argument concerning the present-day uses to which historical maps of Native American lands are put
(D) An argument concerning the nature of information contained in maps of Native American lands
(E) A proposal for improving the accuracy of maps of Native American lands

答案是D   我选的C    我觉得C很对啊  唉。。。

额 C的意思应该是一个关于美国土地的历史上的地图的现在用处的argument 可是文章中没有说现在的用处是什么丫
D是说一个关于包含在美国土地地图中的信息的本质

第二段很多都是在提示说的信息丫 尤其是  Thus our current cartographic record relating to 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.

这句话就是再说隐藏在这些信息的本质丫
