GWD1-17

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?

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.

答案是E，为什么B不对？

啊,突然明白了一点,但是不肯定,不过我觉得也有道理,就是文中指"．．．ＨＯＬＥＳ　ＯＮ　Ａ　ＦＲＡＧＭＥＮＴ"，断片上有３－６个音阶，所以如果找到完整的骨头，就有可能是有全部的音节了．所以Ｅ选相提供了一个可能性～　

加强和假设不同，如果假设就一定是必要条件，而加强只要有增加结论的可能性也就可以了．

希望牛牛们指正我的想法．谢谢！
