(25075-!-item-!-188;#058&001412) 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 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 introduces evidence to support the main conclusion of the argument; the second is the main conclusion stated in the argument. B. The first introduces evidence to support the main conclusion of the argument; the second presents a position to which the argument is opposed. C. The first describes a discovery as undermining the position against which the argument as a whole is directed; the second states the main conclusion of the argument. D. The first introduces the phenomenon that the argument as a whole seeks to explain; the second presents a position to which the argument is opposed. E. The first introduces the phenomenon that the argument as a whole seeks to explain; the second gives a reason to rule out one possible explanation. 74.

When, as often happens, a collar slips off, it is put back on. Putting a collar on a rhinoceros involves immobilizing the animal by shooting it with a tranquilizer dart. Female rhinoceroses that have been frequently recollared have significantly lower fertility rates than uncollared females. Probably, therefore, some substance in the tranquilizer inhibits fertility. In evaluating the argument, it would be most useful to determine which of the following? A. Whether there are more collared female rhinoceroses than uncollared female rhinoceroses in the park B. How the tranquilizer that is used for immobilizing rhinoceroses differs, if at all, from tranquilizers used in working with other large mammals C. How often park rangers need to use tranquilizer darts to immobilize rhinoceroses for reasons other than attaching radio collars D. Whether male rhinoceroses in the wildlife park lose their collars any more often than the D....
