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 diatonic 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. |
选E?这个腿骨够长。。。 Background information: This year, each film submitted to the Barbizon Film Festival was submitted in one of ten categories. For each category, there was a panel that decided which submitted films to accept. Fact 1: Within each category, the rate of acceptance for domestic films was the same as that for foreign films. Fact 2: The overall rate of acceptance of domestic films was significantly higher than that of foreign films. In light of the background information, which of the following, if true, can account for fact 1 and fact 2 both being true of the submissions to this year's Barbizon Film Festival?
|
| A | In each category, the selection panel was composed of filmmakers, and some selection panels included no foreign filmmakers. |
|
| B | Significantly more domestic films than foreign films were submitted to the festival. |
|
| C | In each of the past three years, the overall acceptance rate was higher for foreign than for domestic films, an outcome that had upset some domestic filmmakers. |
|
| D | The number of films to be selected in each category was predetermined, but in no category was it required that the acceptance rate of foreign films should equal that of domestic films. |
|
| E | Most foreign films, unlike most domestic films, were submitted in categories with high prestige, but with correspondingly low rates of acceptance. |
也不懂。。 最后一个: In the nation of Partoria, large trucks currently account for 6 percent of miles driven on Partoria's roads but are involved in 12 percent of all highway fatalities. The very largest trucks—those with three trailers—had less than a third of the accident rate of single-and double-trailer trucks. Clearly, therefore, one way for Partoria to reduce highway deaths would be to require shippers to increase their use of triple-trailer trucks. Which of the following, if true, most seriously weakens the argument?
|
| A
| Partorian trucking companies have so far used triple-trailer trucks on lightly traveled sections of major highways only. |
|
| B
| No matter what changes Partoria makes in the regulation of trucking, it will have to keep some smaller roads off-limits to all large trucks. |
|
| C
| Very few fatal collisions involving trucks in Partoria are collisions between two trucks. |
|
| D
| In Partoria, the safety record of the trucking industry as a whole has improved slightly over the past ten years. |
|
| E
| In Partoria, the maximum legal payload of a triple-trailer truck is less than three times the maximum legal payload of the largest of the single-trailer trucks. | 下周考试了 请大家帮忙解答 万分感谢~ |
