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.
答案是E 请问为什么啊？ 这题意思不太理解 ，请高手详细讲解！谢谢

这种选项叫搭桥。你读题目的时候有没有觉得，证据和结论之间有条沟？证据是4个音，结论是7个音，如果那帮古人做的乐器就只是4个音的呢？那么后代的7个音的就和他们没关系了吧，所以你得把这条沟填上，叫搭桥，丫们其实有条件做完整的（7个音的）乐器：有工具（洞穴熊腿骨？orz）

能解释一下B怎么排除？ 因为B意为：N Campsite的flute是使用7阶音最早的, 不就支持了结论：7阶音在西方音乐家之前就使用了。
