Q17: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.
Which of the following, if true, most strongly supports the hypothesis?
A: Bone flutes were probably the only musical instrument made by Neanderthals.
B: 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.
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 playing 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 a complete diatonic scale.
答案是E.
想请问一下为什么C不正确。
Which of the following most logically completes the argument below?
laceName w:st="on">DavisonlaceName> laceType w:st="on">RiverlaceType> farmers are currently deciding between planting winter wheat this fall or spring wheat next spring. Winter wheat and spring wheat are usually about equally profitable. Because of new government restrictions on the use of laceName w:st="on">DavisonlaceName> laceType w:st="on">RiverlaceType> water for irrigation, per acre yields for winter wheat, though not for spring wheat, would be much lower than average. Therefore, planting spring wheat will be more profitable than planting winter wheat, since‗‗‗‗‗‗.
A：the smaller-than-average size of a winter wheat harvest this year would not be compensated for by higher winter wheat prices
B：new crops of spring wheat must be planted earlier than the time at which standing crops of winter wheat are ready to be harvested
C：the spring wheat that farmers in the laceName w:st="on">DavisonlaceName> River region plant is well adapted to the soil of the region
D：spring wheat has uses that are different from those of winter wheat
E：planting spring wheat is more profitable than planting certain other crops, such as rye
虽然用排除法选择了A，但还是太明白A的意思。
谢谢各位的帮忙。 |
