Most of Western music since the Renaissance has been based on a seven-note scale known as the diatonic scale, but when did the scale originate? A fragment of a bone flute excavated at a Neanderthal campsite has four holes, which are spaced in exactly the right way for playing the third through sixth notes of a diatonic scale. The entire flute must surely have had more holes, and the flute was made from a bone that was long enough for these additional holes to have allowed a complete diatonic scale to be played. Therefore, the Neanderthals who made the flute probably used a diatonic musical scale.
In the argument given, the two portions in boldface play which of the following roles?
The first is presented as evidence that is confirmed by data presented elsewhere in the argument given; the second states a hypothesis that this evidence is used to undermine.
The first is an opinion, for which no supporting evidence is presented in the argument given, that is used to support the main conclusion of the argument; the second is that main conclusion.
The first describes a discovery as undermining the position against which the argument is directed; the second states the main conclusion of the argument.
The first is a preliminary conclusion drawn on the basis of evidence presented elsewhere in the argument given; the second is the main conclusion that this preliminary conclusion supports.
The first provides evidence to support the main conclusion of the argument; the second states a subsidiary conclusion that is drawn in order to support the main conclusion stated earlier in the argument.
The entire flute must surely have had more holes, and the flute was made from a bone that was long enough for these additional holes to have allowed a complete diatonic scale to be played.
当时选了D是因为觉得后半句是前半句也就是第一处黑体部分的evidence，但实际上并不是，从and这个连接词可以看出来，前后两部分都只是猜测，不存在谁支持谁，而且这种猜测怎么都算不上evidence的
D：表示第一个是有证据支持的，但文中并没有。
以上两点对于结论只能起辅助作用，无法推翻诸如一切只不过是巧合的质疑，无法证明这有4个洞的骨头就是有7个洞的scale，所以第一个只是opinion，no supporting evidence is presented for it
第一句是一个观点，在句子中并没有给出支持性的证据，被用作支持主要结论，
可以发现，第一个黑体句前后是猜测，所以不足以充当证据
用排除法：
A hypothesis，第二部分是假设，排除
E a subsidiary conclusion，排除。
剩下BCD：
C 第一部分是discovery，第一部分是个推测，不是事实，排除
D 第一部分是preliminary conclusion，第一部分是个推测，不是结论，排除。

题干没有出现转折的意思。先说文艺复兴后用的是七个音阶。第一段粗体字说：一残缺笛子有4个洞，大概排列顺序与7音阶比较搭搭。接着说应该有第二段粗体说：笛子很可能用的就是7个音阶（有7个洞）。
由于题干无转折，全是支持，所以选项中第二句话出现反对的都错，排除BDE，比较AC的第一句话，C的第一句也是反对的，意思是：第一句缩小了一个整段都反对的立场。无中生有。选A

entire flute有更多的洞这件事是没有evidence支持的，我们只是知道flute够长，洞会更多只是猜测。登录 或 注册 后可以参加讨论
