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 examination of the find shows that
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?
A. The first states the hypothesis that the argument seeks to support; the second presents evidence to support a conclusion that, in turn, supports the argument’s main conclusion.
B. The first states the hypothesis that the argument seeks to support; the second introduces evidence that has been used to argue against the argument’s main conclusion.
C. The first is a judgment that is used to support the main conclusion of the argument; the second introduces evidence to support that conclusion.
D. The first is a judgment that is used to support the main conclusion of the argument; the second presents evidence restricting the scope of that judgment.
E. The first is a conclusion drawn on the basis of evidence stated elsewhere in the argument; the second is the argument’s main conclusion.
