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.

evidence是出土的Neanderthal人的笛子碎片中有四个孔是第三音阶到第6音阶，这四个音阶是全音阶（也就是7个音阶）所必须的，全音阶是后来西方人广为使用的。结论是音乐家猜测全音阶在西方人使用前就有了。

所以可以推出来音乐家的猜测是认为出土的碎片是全音阶的，碎片只有4个音阶，可能保存不当或者什么原因其他3个孔没了，总之可以认为出土的笛子可以有7个孔。所以E就是说这个意思的，说熊的骨头足够的长可以做出来7个孔。
