Traces of cultivated emmer wheathave been found among the earliest agricultural remains of many archaeologicalsites in Europe and Asia. The only placewhere the wild form of emmer wheat has been found growing is a relativelynarrow strip of southwest Asia. Sincethe oldest remains of cultivated emmer wheat yet found are from village sitesin the same narrow strip, it is clear that emmer wheat was first domesticatedsomewhere in that strip.
Which of the following, if true,most strengthens the argument?
(A) The present-day distribution ofanother wild wheat, einkorn, which was also domesticated early in thedevelopment of agriculture, covers a much larger area of southwest Asia.
(B) Modern experiments show thatwild emmer wheat can easily be domesticated so as to yield nearly as well astraditionally domestic strains.
(C) At the time when emmer wheatwas first cultivated, it was the most nutritious of all the varieties of grainthat were then cultivated.
(D) In the region containing thestrip where wild emmer wheat has been found, climatic conditions have changedvery little since before the development of agriculture.
(E) It is very difficult, withoutgenetic testing, to differentiate the wild form of emmer wheat from a closelyrelated wild wheat that also grows in southwest Asia.
原文说在同一个strip发现了最早wild 的emmer，然后最早发现的人工培育的也在那，那么中间的gap就是野的转成人工的么
关于D，天气在农工业开始之前几乎没变过只能说明wild一直比较好的生存直到农业开始发展
并不能说明domestic最早在那个strip啊。。。
