1.这道题目我都没看懂～～ 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 seven-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. 这道题目我都没看懂～～ 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 seven-note musical scale used in much of Western music since the Renaissance.

Which of the following, if true, most strongly supports the hypothesis?
- Bone flutes were probably the only musical instrument made by Neanderthals.
- No musical instrument that is known to have used a diatomic scale is of an earlier date than the flute found at the Neanderthal campsite.
- 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.
- Flutes are the simplest wind instrument that can be constructed to allow playing a diatonic scale.
- The cave-bear leg bone used to make the Neanderthal flute would have been long enough to make a flute capable of playing a complete diatonic scale.
2.为什么D是错的俄？ Garnet and RenCo each provide health care for their employees. Garnet pays for both testing of its employees’ cholesterol levels and treatment of high cholesterol.

A. early treatment of high cholesterol dose not entirely eliminate the possibility of a stroke later in life B. the mass media regularly feature stories encouraging people to maintain diets that are low in cholesterol C. RenCo has significantly more employees than Garnet has D.
