文中有定義the diatonic scale(全音阶)就是7音阶 —the seven-note musical scale used in much of Western music since the Renaissance ,而hypothesize是说the diatonic musical scale was developed and used thousands of years before it was adopted,就是说全音阶在以前就被developed并且used过了。因此在Neanderthal campsite发现的leg bone要有7孔为前提就能证明以上的假说。>>
选项E 支持结论。>>

另说一下,以前我选B,是认为,4孔也能发展为全音阶。>>
“the diatonic musical scale was developed and used thousands of years before it was adopted”这个假设并未断言一定是从7孔才能到全音阶。当然也有可能是Neanderthal campsite发现的4孔leg bone经过几千年的进化成为了现在的7音阶的complete diatonic scale。>>
后来仔细琢磨了对于the diatonic scale的定义,如果发现的leg bone 仅仅是4孔,不管它是不是最早,根本就不能算the diatonic scale,也不能支持假说的developed and used thousands of years before。
选B的同学看看有没有这个误解的? |
