※ 引述《tecoteco (teco)》之銘言：
: 21.
: 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?

原題的因果關係：cultivated emmer 最早被發現在strip --->
                emmer最先在strip被domesticated

: (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.

      another wild wheat: 擴大議題範圍，轉移焦點

: (B) Modern experiments show that wild emmer wheat can easily be domesticated so
:     as to yield nearly as well as traditionally domestic strains.

      emmer wheat vs traditionally domestic strains：無關比較

: (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.

      most nutritious: 與原題因果關係無關

: (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.

      正解；有利因素，可佐證原題因果關係正確


: (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.

      genetic testing: 與原題因果關係無關

: 正確答案是 D
: 可是我實在看不懂
: 有請好心人士幫忙解答
: 謝謝!!

  這題用排除法可能比較好做

推 tecoteco:還是不懂  strip氣候穩定跟emmer最先在strip
→ tecoteco:被domesticated有什麼關係?
→ wayshawn:http://ppt.cc/48Kw；CD上的討論，很多人也有類似的問題
→ wayshawn:可以看看5, 6樓的說法，你接不接受吧
→ wayshawn:AT的support題，很多跟原題因果沒有那麼相關，但是是提出
→ wayshawn:有利的條件藉以支持；像是樣本具代表性，本質相同狀況，
→ wayshawn:或是排除其他可能影響原題因果的他因
→ wayshawn:講起來很玄了，我也不太會解釋，有時候正確選項跟無關選
→ wayshawn:項也就一線之隔；看有沒有其他的強者可以補充吧..謝謝
→ wayshawn:偷一下兔大的解釋：自從有了農業的發展以來這些區域的氣
→ wayshawn:候環境沒有發生變化, 因此至少在環境條件上說明古emmer
→ wayshawn:可以在這裡被利用。注意加強不一定是充分條件。
推 tecoteco:好像有點感覺了  這題只能選"相對比較好的答案"  感謝!!
