21. (28551-!-item-!-188;#058&003690) ？
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.
为什么选D，关天气什么事啊？
还是没明白~~谁再来给我说说~~大谢~~
说下我的想法，其实我也是做错以后重新反省，所以如果还是没有理解正确，还请大家批评指正……
C在最古老的农业遗址里发现过。W只长在某一块地上。因为有C的最老的遗迹也在这一块地上，所以C是在这块地上开始被驯化的（即W变成C就在这个地上）。
抽象一点考虑( 破折号表示有关联，不表示因果推导）：
第一句话C——遗址，
第二句话W——地
第三句话遗址——地
第1、3两句：C——遗址——地，
结论是W——C——地。
我就去找同时出现W& C
A：W的同类怎样。横向错误类比
B：W，C，别的种类。
C：C，别的种类。
D：地，W——C——天气
E：W，别的种类。
不管天气是怎么回事， 它让W和C建立了联系，且非负相关。
谈点个人理解：
原文结论是，Southwest Asia的某个narrow strip是唯一发现还有生长着emmer wheat的地方，又因为最老的remains of cultivated emmer wheat也是同样在位于那个strip的村庄发现的，所以emmer wheat最早是在那个strip的某处被种植的。
下面来看下面哪个选项最能加强这个结论：
(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. 无关，结论是关于emmr wheat的
(B) Modern experiments show that wild emmer wheat can easily be domesticated so as to yield nearly as well as traditionally domestic strains. 说emmer wheat可以随便种种，和原文矛盾
(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. 无关
(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. support结论，因为在发现种植有wild emmer wheat的地方，气候从农业刚开始发展到现在变化都不大，即最早种植emmer wheat到现在都没变化
(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. 无关
