ＧＷＤ上的题目

GWD1-Q17:

The spacing of the four holes on a fragment of a bone flute excavated at a Neanderthal campsite is just what is required to play the third through sixth notes of the diatonic scale—the seven-note musical scale used in much of Western music since the Renaissance.  Musicologists therefore hypothesize that the diatonic musical scale was developed and used thousands of years before it was adopted by Western musicians.

Which of the following, if true, most strongly supports the hypothesis?

A. Bone flutes were probably the only musical instrument made by Neanderthals.

B. No musical instrument that is known to have used a diatomic scale is of an earlier date than the flute found at the Neanderthal campsite.

C. The flute was made from a cave-bear bone and the campsite at which the flute fragment was excavated was in a cave that also contained skeletal remains of cave bears.

D. Flutes are the simplest wind instrument that can be constructed to allow playing a diatonic scale.

E. The cave-bear leg bone used to make the Neanderthal flute would have been long enough to make a flute capable of playing a complete diatonic scale.

求问为什么选E呢？文中没有提到cave-bear leg啊？

原文逻辑：骨头笛子残片能演奏diatonic scale中的第3到第6个，所以diatonic scale早在数千年前就在使用了。

E：有种动物（cave-bear）的骨头能长到可以演奏整个的diatonic scale

E补充了一个逻辑，即这个笛子除了能演奏diatonic scale的第3到第6个，还能演奏第1、第2和第7个。即为古人能够演奏完整的diatonic scale提供了依据，当然是强化了结论。

文中没提到cave-bear leg又怎样。。。。。。为啥一定要提到cave-bear leg。。。。

恩，这个明白了。但是不知道为什么B不对，如果没有找到比在N campsite更早的有diatonic scale的长笛，那么不是可以支持这个发现比西方音乐家使用长笛早吗？

就算B不成立，也就是就算存在更早用diatomic scale的乐器，全文的结论仍然成立，即早在数千年钱人们就在用diatomic scale了。

所以不能选B

你把B的意思看反了吧。。
