Traces of cultivated emmer wheat have been found among the earliest agricultural remains of many archaeological sites in Europe and
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
(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
【答案】D
我的分析：
A是无关类比
B实验信息，无关类比
C营养与题干无关
D生产区域气候变化与题干无关
E辨识emmer wheat 难易度与判断 first domesticated 无关
答案选择D，是不是因为排除了一个可以影响emmer wheat 培育的因素——气候在emmer wheat 从野种到被人培育期间并没有改变，于是使得emmer wheat 是首先在这片区域被驯化成为可能，而不是现在欧洲再在亚洲。
但我总感觉D让人不是很舒服，纵然气候没有明显变化也不能支持结论啊……
望NN们指教
肯定相同因素的加强
