Traces of cultivated emmer wheat have been found among the earliest agricultural remains at many archaeological sites in Europe and Asia. The only place where the wild form of emmer wheat has been found growing is a relatively narrow strip of southwest Asia. Since the oldest remains of cultivated emmer wheat yet found are from village sites in the same narrow strip, it is clear that emmer wheat was first domesticated somewhere in that strip.
Which of the following, if true, most strengthens the argument?
A. The present-day distribution of another wild wheat, einkorn, which was also domesticated early in the development of agriculture, covers a much larger area of southwest Asia.
B. Wild emmer wheat can easily be made to yield nearly as much as modern domestic strains.
C. At the time when emmer wheat was first cultivated, it was the most nutritious of all the varieties of grain that were then cultivated.
D. In the strip where wild emmer wheat has been found, climatic conditions have changed very little since before the development of agriculture.
E. It is very difficult, without genetic testing, to differentiate the wild form of emmer wheat from a closely related wild wheat that also grows in southwest Asia
楼主你好:这道逻辑题干我的理解如下:
一些农业遗迹中发现有种植小麦的痕迹, 而仅仅在南亚的一个狭小地带发现了野生小麦, 同时目前发现的最古老的种植小麦也是在那里种植的,
结论:因此种植小麦第一次培育就是在这个狭小地带被培育出来的。
说实在的我不太理解这其中的逻辑链,为什么能得出这个结论呢?
目前发现的最早的不代表就是最早的呀。如果还有更早的种植小麦残骸没被发现,而这些小麦可能在其他地方有呢。麻烦楼主分析下这个因果逻辑链呢。
还有正确答案说的气候问题,我感觉很容易被当成无关选项pass掉呢,请问下楼主是怎么思考这个题的呢,感谢!! |
