122. The spacing of the four holes on a fragment of a bone fl ute 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 fl utes were probably the only musical instrument made by Neanderthals.
(B) No musical instrument that is known to have used a diatonic scale is of an earlier date than the fl ute found
at the Neanderthal campsite.
(C) The fl ute was made from a cave-bear bone and the campsite at which the fl ute 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 fl ute would have been long enough to make a fl ute
capable of playing a complete diatonic scale.作者: vakaka 时间: 2012-10-10 06:43
"required to play the third through sixth notes of the diatonic
Premise : flut fragment can play part of diatonic scale
Conclusion: diatonic musical scale was developed and used thousands of years
Gap: exist....
So there must be a supportive assumption to make sense this conclusion.
the flut original lenth are long enough to play full DM....

文章中说音乐家假设全音阶在被正式使用前已经有几千年的历史
而N城发现的骨笛只能吹出4个音，但全音阶有7个音，因此文章缺的gap是只有在那时有发现能吹出7个音的乐器，才能证明音乐家的假设
A 说骨笛是唯一被发现的乐器，也就没有其他能吹7个音的乐器，weaken
B 说在骨笛之前没有任何乐器，就没有能吹出7个音乐器的可能性，weaken
E 说发现的熊腿骨足够长吹出7个音，也就证明了当时就有类似的乐器存在，所以加强作者: huanzitou 时间: 2012-10-11 20:24
