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E 不太懂为啥腿骨头和题目有啥关系。。

发现东西的只是一段fragment 并不是完整的笛子  它的上面只有 三个音孔
然而凭借这个就说它是第一个能弹奏全音阶的乐器（七声音阶：1 2 3 4 5 6 7）  显然是缺乏证据的。
因此 E选项 那时候远古人用的熊骨头 长度刚刚好能做这么个能弹奏全音阶乐器。 是不是就色破特了 这段fragment 就是第一只能够playa complete diatonic scale呢？
