看看这个吧

感觉是这样

文中N时代bone中的Hole可满足演奏D的要求，这个D是used in much of Western music ，结论D was developed and used thousands of years before it was adopted by Western musicians.

答案E说明了Bone确实能够满足演奏D的要求。

属于资料准确的支持。

而B中的比较时间对象为 Neanderthal campsite，与文中结论没有关系.

不知对否，请指教

E is right. 

If the bone is long enough to make all notes but there is only four notes, it's proven that the flute was made before the seven-note musical scale was developed.
