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.
OA是D，费解，这个气候有什么关系？ 因为 The only place where the wild form of emmer wheat has been found growing is a relatively narrow strip of southwest Asia. 讲的是现在的事，the oldest remains of cultivated emmer wheat yet found are from village sites in the same narrow strip 那些遗址是几千年前的居住地。结论是 it is clear that emmer wheat was first domesticated somewhere in that strip，因为野麦与遗址在同一地区。但是如果几千年前气候不同，那就很难说那时的野麦，生长在那些遗址附近。 这个题目问的是 野麦是由家麦（就是农民伯伯种的麦。。。不会说那个词。。。“耕田”“耕麦”？？::z8 。。。）来的？ 还是正相反？？
另外 D) In the region containing the strip where wild emmer wheat has been found, climatic conditions have changed very little[color=red] since before[/color] the development of agriculture.
since before 是什么意思？？ 是不是多印了一个“before" ???::p3

为什么你会这样说？题干说的是什么？
since before 不是一个单位。since (before the development of agriculture)。你看，意思与 since the development of agriculture 是否一样？ ::16 thank u!::83 明白了 感谢大家
