?122. 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.[c1]

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

(A) Bone flutes were probably the only musical instrument[c2] made by Neanderthals.

(B) [c3]No musical instrument that is known to have used a diatonic 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.[c4]

(D)[c5] Flutes are the simplest wind instrument that can be constructed to allow playing a diatonic scale.

(E)[c6] 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.E

[c1]因果型结论



[c2]与时间无关



[c3]无关



[c4]无关



[c5]无关



[c6]填补GAP

不是很理解为什么选E,哪位大牛帮助详细分析一下?

The flute found could only play from the 3rd to the 6th note of the 7-note scale.  It is possible that this flute could ONLY play this 4 notes instead of the required 7th.  

Answer E claims that the flute, at least based on its original length, could play the full notes. In other words, E makes sure the bone from which the flute is made is possible to support the 7 holes required for the 7-note diatonic scale.

D   Flutes are the simplest wind instrument that can be constructed to allow playing a diatonic scale
D选项说flute是最简单的乐器

D项解释是 this does not strengthen the hypothesis ,for even if the option were false---even if a simpler instrument could be constructed that employed the diatonic scale---the existence of a flute emplying the diatonic scale would provide no less support for the hypothesis. 这个解释是什么意思啊??看不明白??
reasoning 里面有一句if the option were false , would the hypothesis be less likely to be true.  

但是我还是不明白D选项以及解释在说什么,啥意思阿???

Option D has no impact on the hypothesis. The explanation says that even if D is wrong, meaning another instrument is the simplest instrument that could play the diatonic scale, the existence of a flute which can play the diatonic scale still supports the hypothesis. Therefore, D itself is not a supporter since if D is wrong, the conclusion still holds.
