选项

B、reconcile opposing viewpoints.
C、refute a common misconception.

答案
A
解析
全文主旨题。本题问,本文的主要写作目的是什么?本文第1段指出:"1492年美洲土著民族的人口(最新估计上升到一亿或接近于那时世界人口的六分之一)与 19世纪末仅剩的几百万纯血统的印第安人之间的差距甚大,对此历史学家越来越多地归因于欧洲(Old World)传入的疾病。毫无疑问,慢性病是人口锐减的重要原因,而传染病很可能是最大的杀手,尤其是处女地流行病"。然后作者就此在以下各段中进行论证。可见,作者写本文是为了对第1段中提出的假设提供论据。注意:本文语言和题目都有较大难度。这样的文章和试题要反复推敲起码3—5遍,直到把文章的每一细节和题目的每一选项全部搞懂为止。
