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.
C: emmer wheat was domesticated in that strip.
P: wild and remains of cultivated are both found in that strip.
因果-QUOTE RON “have been found growing”这个是在讲野生的现在也在生长；选项要能放在P和C之间而加强的，做题问自己“为什么被一起发现，就能证明是在那家养的呢”？思路有两个，一个是有了这个选项，可以更加正向增强【因果联系】；另一个是基于这个前提下，没有其他因素【干扰因素】。D说明两者没有存在其他干扰因素。
