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?(D)

 

1. Bone flutes were probably the only musical instrument made by Neanderthals.

2. 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.

3. 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.

4. Flutes are the simplest wind instrument that can be constructed to allow playing a diatonic scale.

5. 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.

E好像说的离提,为甚没答案选它呢??

spacing :间距, 只有E中的长度和间距有关.

这个CR讲的是发现了一个骨笛上4个洞的间距可以恰好是可以用来PLAY MUSICAL SCALE的，于是推论这种MUSICAL SCALE早在那时就已经被发展并使用了。

有人选B，但B是无关。B讲，没有比N人用的那个骨笛更早的可以PLAY MUSICAL SCALE的乐器。但是有没有这样一种更早的乐器跟结论“N人比文艺复兴时期西方音乐家的早几千年使用MUSICAL SCALE”无关。如果不好想的话，我们可以把B取非，因为无关选项，即便取非也会同样无关，我们来看是不是这样。取非的结果也就是说有这样一种比N人的骨笛更早的可以PLAY MUSICAL SCALE的乐器，但是即便有这样一种乐器，也无法影响到结论，结论比较的是N人与文艺复兴时期的音乐家，即使有更早的乐器，N人比西方音乐家早几千年使用MUSICAL SCALE的结论也不会受到丝毫影响。

这里要注意隐含的要素，文章一开始只是说发现了这样一种东西恰好可以PLAY MUSICAL SCALE的，然后就根据这个可能是巧合的发现推了结论。那么文章可能的逻辑漏洞就是这个“巧合”确实就是一个巧合。如果要加强，就要证明这个不是巧合，也就是证明“因”可行或有意义，E恰好是证明了这一点。
