In a six-month trial of a new therapy for this type of ul

2、cer, 80 percent of ulcers treated achieved significant healing and 61 percent were completely healed. Since the trial treated only ulcers of this type that were worse than average, the new therapy clearly promotes healing more effectively than the most widely used therapy. The answer to which of the

3、 following would be most useful in evaluating the argument given? (A) What differences are there, if any, in the ways that the two therapies are administered? (B) Is there any significant difference between the costs associated with the two therapies? (C) What percentage of people with ulcers of thi

4、s type who were treated with the most widely used therapy for six months experienced significant healing? (D) How quickly do ulcers of this type, if left untreated, become significantly worse?

6、lt of the interest taken by researchers in the work of both groups during the study. Which of the following, if true, would cast most doubt upon the authors interpretation of the study results given above? (A) The 50 workers moved to the brightly colored room performed precisely the same manufacturi

7、ng task as the workers who remained in the drab workroom. (B) The drab workroom was designed to provide adequate space for at most 65 workers. (C) The 50 workers who moved to the brightly colored workroom were matched as closely as possible in age and level of training to the 50 workers who remained

8、 in the drab workroom. (D) Nearly all the workers in both groups had volunteered to move to the brightly colored workroom. (E) Many of the workers who moved to the brightly colored workroom reported that they liked the drab workroom as well as or better than they liked the brightly colored workroom.

9、 3.Every human being who has ever lived had two parents. Therefore, more people were alive three thousand years ago than are alive now. The reasoning in the argument is flawed because it (A) overlooks the number of people in each generation during the last three thousand years who left no descendant

10、s. (B) disregards possible effects of disasters such as famines and plagues on human history. (C) overestimates the mathematical effect of repeated doublings on population size.

13、$100 less (D) $300 less (E) $1,500 less 5.Essayist: The existence of a moral order in the universei.e., an order in which bad is always eventually punished and good rewardeddepends upon human souls being immortal. In some cultures this moral order is regarded as the result of a karma that controls h

14、ow one is reincarnated, in others it results from the actions of a supreme being who metes out justice to people after their death. But however a moral order is represented, if human souls are immortal, then it follows that the bad will be punished. Which one of the following most accurately describ

15、es a flaw in the essayists reasoning? (A) From the assertion that something is necessary to a moral order the argument concludes that that thing is sufficient for an element of the moral order to be realized. (B) The argument takes mere beliefs to be established facts. (C) From the claim that the im

16、mortality of human souls implies that there is a moral order in the universe, the argument concludes that there being a moral order in the universe implies that human souls are immortal. (D) The argument treats two fundamentally different conceptions of a moral order as essentially the same. (E) The

17、 arguments conclusion is presupposed in the definition it gives of a moral order. 6.

23、 the expense of maintaining a heroin addiction and the fear of arrest. If heroin were legalized and made available cheaply, as some people advocate, neither of these reasons would apply. The considerations above can best serve as part of an argument that (A) legalizing the sale of heroin would cause

24、 the price of this drug to go down. (B) making it easier for heroin addicts to obtain treatment for their addiction would encourage many heroin addicts to attempt to overcome their addiction.

34、s have traditionally held the view that Antarctica was first sighted around 1820, but some sixteenth-century European maps show a body that resembles the polar landmass, even though explorers of the period never saw it. Some scholars, therefore, argue that the continent must have been discovered and

35、 mapped by the ancients, whose maps are known to have served as models for the European cartographers. Which of the following, if true, is most damaging to the inference drawn by the scholars? (A) The question of who first sighted Antarctica in modern times is still much debated, and no one has been

48、 the last ten years have been found to contain indoor air pollution at levels that are, on average, much higher than the levels found in older houses. The reason air-pollution levels are higher in the newer houses is that many such houses are built near the sites of old waste dumps or where automobi

49、le emissions are heavy. Which of the following, if true, calls into question the explanation above? (A) Many new houses are built with air-filtration systems that remove from the house pollutants that are generated indoors. (B) The easing of standards for smokestack emissions has led to an increase

50、in air-pollution levels in homes. (C) New houses built in secluded rural areas are relatively free of air pollutants. (D) Warm-weather conditions tend to slow down the movement of air, thus keeping pollution trapped near its source. (E) Pressboard, an inexpensive new plywood substitute now often use

51、d in the construction of houses, emits the pollutant formaldehyde into the house. 21.Our words are meaningless and cannot be distinguished from their opposites, as can be proved by an example. People think that they know the difference between the meanings of bald and having hair. Suppose an average

52、 person twentyone years of age has N hairs on his or her head. We say that that person is not bald but has hair. But surely one hair less would make no difference, and a person with N-1 hairs on his or her head would be said to have hair. Suppose we kept on, with one hair less each time. The result

53、would be the same. But what would be the difference between someone who had one hair and someone who had none? We call them both bald. Nowhere can we make a distinction between bald and having hair. Which of the following statements best counters the argument above? (A) The word bald can be translat

54、ed into other languages. (B) A word can have more than one meaning. (C) A word such as cat can be applied to several animals that differ in some respects. (D) Words can lack precision without being meaningless. (E) People cannot think clearly without using words. 22.Fares on the city-run public buse

55、s in Greenville are subsidized by city tax revenues, but among the beneficiaries of the low fares are many people who commute from outside the city to jobs in Greenville. Some city councilors argue that city taxes should be used primarily to benefit the people who pay them, and therefore that bus fa

56、res should be raised enough to cover the cost of the service. Each of the following, if true, would weaken the argument advanced by the city councillors EXCEPT: (A) Many businesses whose presence in the city is beneficial to the citys taxpayers would relocate outside the city if public-transit fares

57、 were more expensive. (B) By providing commuters with economic incentives to drive to work, higher transit fares would worsen air pollution in Greenville and increase the cost of maintaining the citys streets. (C) Increasing transit fares would disadvantage those residents of the city whose low inco

58、mes make them exempt from city taxes, and all city councillors agree that these residents should be able to take advantage of city-run services. (D) Voters in the city, many of whom benefit from the low transit fares, are strongly opposed to increasing local taxes. (E) People who work in Greenville

59、and earn wages above the nationally mandated minimum all pay the city wage tax of 5 percent. 23.The major goal of physical education programs in schools is to help all children become physically fit. But only a small proportion of children ever participate in team sports. Moreover, team sports usual

60、ly do less to encourage fitness in participants than do physical education programs that focus directly on aerobic exercise. The considerations above, if true, could be used most effectively to argue against (A) the use of in-school physical education programs to encourage lifelong fitness habits in
