122、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 secen-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 ture, most strongly supports the hypothesis?
(A) Bone flutes were probably the only musical instrument made by Neanderthals.
(B) No musical instrument that is know to have used a diatonic scale is of an earlier date than the flute found at the Neanderthal campsite.
(C) 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.
(D) Flutes are the simplest wind instrument that can be constructed to allow palying a diatonic scale.
(E) The cave-bear leg bone used to make the Neanderthal flute would have been long enough to make a flute capable of playing ac complete diatonic scale.
答案选E,该怎样理解呢?E的意思是说那个骨头足够长来制作长笛来演奏全音阶,那就是说当时的笛子没有全音阶,就表示他用了长时间来发展和使用?是这样理解吗?

原文发现的fragment of a bone flute只能演奏third through sixth notes of the diatonic scale，就是说不能演奏全音阶。假说认为the diatonic musical scale在几千年前已经使用了。逻辑链上面还缺少一个条件：这个bone flute是否能演奏全音阶。
E)给出了bone flute能演奏全音阶的可行性，补齐逻辑链，加强。
