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.
对这道题目很不理解，答案是E，哪冒出来的cave-bear?? 跪求帮忙解释下。。

Support：support题逻辑关系和解题思路都不是很难，推理的重点在结论上。不过，因为support题只要求答案有一定的支持作用就行，所以答案的给出往往千奇百怪，经常让人无法选择。答案也不太容易预测。值得一提的是assumption答案是support答案的子集。
E  熊的骨头可以做全音阶，是原文的一个assumption,支持了选项

这道题目的逻辑链是：长笛的fragment出现推出scale出现，所以scale早出现在N，比W早

A：bone flute是N的唯一乐器，但不等于diatonic musical scale，无关
B：没有比N更早的了，不能解释题目的结论在W之前
C：还有熊的骨头，不能完全肯定fragment就是长笛的；削弱
D：长笛是演绎scale最简单的构成，无关

E：熊的骨头可以做全音阶 支持

题干没有，E选项提供的信息。没有说选项的信息不能超出题干吧。关键是理解题干，才知道选项多出的信息是否support题干。
