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?
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.
Modern experiments show that wild emmer wheat can easily be domesticated so as to yield nearly as well as traditionally domestic strains.
At the time when emmer wheat was first cultivated, it was the most nutritious of all the varieties of grain that were then cultivated.
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.
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.
因果,
∵种植的EW与野生的同时出现在某一strip
∴在这strip的某地,EW是头一回被人工种植
加强,排除干扰因素(CQ1)或排除一因多果、因果没有联系(CQ2)
A、另一种从野生变为人工种植的W cover了一片更广阔的area,甚至在削弱;没有他因
B、EW被家养了之后产量和传统的家养粮食一样好,NM野生
C、EW最有营养,NM野生
D、EW野生的地方的气候变化,自农业发展以来不大;排除干扰因素”气候“对种植、野生EW同时出现的影响,加强,CORRECT
E、EW很难与另外一种W区分,甚至在削弱
