The flute found could only play from the 3rd to the 6th note of the 7-note scale. It is possible that this flute could ONLY play this 4 notes instead of the required 7th.
Answer E claims that the flute, at least based on its original length, could play the full notes. In other words, E makes sure the bone from which the flute is made is possible to support the 7 holes required for the 7-note diatonic scale.
