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.

没看懂这段原文表达啥意思?

一种麦子的最早人中栽培的痕迹在欧洲和亚洲都有发现。最早的这种小麦的鼻祖只亚洲的一个地区发现。因为这种人中栽培的小麦也在这个亚洲地区发现。结论：这种小麦最早是在亚洲这个地区栽培的。

b可能是个混淆选项。b的意思说，现代的试验证明野生的小麦同其他传统种类的作物一样，容易被人工种植。  其实无关

d，取非。这个亚洲地区在种植业开展前过去曾经发生了重大的天气变化。天气肯定是个重大的决定因素，取非后就使结论不那么sound了。因为由于天气剧变，那些野生的小麦就绝种了，后来人们就把异地培养的小麦带到这里来种。这里就不是人类最先培养小麦的地方了
