标题: prep逻辑题请教

Traces of cultivated emmer wheat have been found among the earliest agricultural remains of 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) Modern experiments show that wild emmer wheat can easily be domesticated so as to yield nearly as well as traditionally 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 region containing 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.

我选的是B 请教NN们这题的解题思路 实在理不清

野生的小麦只生长在亚洲,同时最早发现的人工种植小麦也在亚洲。
因此,最早人工种植小麦就在亚洲。

其实这中间是有个gap,就是最早发现不一定是最早的。野生小麦只生长在亚洲,说明那个时候这里气候适宜,但是如果历史上发生大的气候转变的话,也许他们被美国人拿去人工种植了(只是遗址还没有发现)。
所以保证气候的一直很适宜小麦,无疑可以加强结论。

当然了,这个题目其实其实答案扫一遍就会发现ABCE都是无关选项。只有D还能扯上一点关系。
