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（全音节的） scale（音符）—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.（对比）

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.

请问为什么选E呢？

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.

Lacus

题目说，挖出来的骨笛有拿来演奏d.s.的条件，而只有e提过挖出来的骨笛可以用来演奏d.s.
所以这里一定是e。

B为什么不对呢？只有确保没有比这种笛子更早的乐器，才能确定它是后来乐器的源头啊？

sdcar2010

You added a new assumption to the passage: the flute is the origin of the diatonic scale.

However, the passage does not require such an assumption.

Further, "not found" does not equal "never."  Something in hiding might be found later.
