来贴一下今下午看了半天的逻辑题。。 122. 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. 首先这道，是讲一个什么骨头上的四个洞正好能够能够满足一个神马乐器上的四个洞的要求，然后就要找支持这个乐器在被音乐家使用的很早以前就得到了发展。。。。
还有这道 28. Company Alpha buys free-travel coupons from people who are awarded the coupons by Bravo Airlines for flying frequently on Bravo airplanes. The coupons are sold to people who pay less for the coupons than they would pay by purchasing tickets from Bravo. This marketing of coupons results in lost revenue for Bravo. To discourage the buying and selling of free-travel coupons, it would be best for Bravo Airlines to restrict the (A) number of coupons that a person can be awarded in a particular year (B) use of the coupons to those who were awarded the coupons and members of their immediate families (C) days that the coupons can be used to Monday through Friday (Dl amount of time that the coupons can be used after they are issued (El number of routes on which travelers can use the Coupons 囧，看到A后立马选了A，其实限制coupons的总数根本没用，要限制那些有优惠的coupons总数才能防止这个公司这种业务的进行。。。。思维真的好菜。。。
32. A recent spate of launching and operating mishaps with television satellites led to a corresponding surge in claims against companies underwriting satellite insurance. As a result, insurance premiums shot up, making satellites more expensive to launch and operate. This, in turn, had added to the pressure to squeeze more performance out of currently operating satellites. Which of the following, if true, taken together with the information above, best supports the conclusion that the cost of television satellites will continue to increase? (A) Since the risk to insurers of satellites is spread over relatively few units, insurance premiums are necessarily very high. (8) When satellites reach orbit and then fail, the causes of failure are generally impossible to pinpoint with confidence. (C) The greater the performance demands placed on satellites, the more frequently those satellites break down. (D) Most satellites are produced in such small numbers that no economies of scale can be realized. (El Since many satellites are built by unwieldy international consortia, inefficiencies are inevitable.
45. Often patients with ankle fractures that are stable, and thus do not require surgery, are given follow-up x-rays because their orthopedists are concerned about possibly having misjudged the stability of the fracture. When a number of follow-up x-rays were reviewed, however, all the fractures that had initially been judged stable were found to have healed correctly. Therefore, it is a waste of money to order follow-up x-rays of ankle fractures initially judged stable. Which of the following, if true, most strengthens the argument? (A) Doctors who are general practitioners rather than orthopedists are less likely than orthopedists to judge the stability of an ankle fracture correctly. (8) Many ankle injuries for which an initial x-ray is ordered are revealed by the x-ray not to involve any fracture of the ankle. (C) X-rays of patients of many different orthopedists working in several hospitals were reviewed. (D) The healing of ankle fractures that have been surgically repaired is always checked by means of a follow-up x-ray. (E) Orthopedists routinely order follow-up x-rays for fractures of bones other than ankle bones.
