一、单项选择题(共50题,每题2分。每题的备选项中,只有一个最符合题意)

1.The most widely used therapy for a certain type of ulcer completely heals such ulcers in 44 percent of patients within six months. In a six-month trial of a new therapy for this type of ulcer, 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 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 this 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? (E) What percentage of patients involved in the six-month trial of the new therapy were disappointed at the rate of healing that were experiencing?

2.In a study of the effect of color on productivity, 50 of 100 factory workers were moved from their drab workroom to a brightly colored workroom. Both these workers and the 50 who remained in the drab workroom increased their productivity, probably as a result 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 author's interpretation of the study results given above? (A) The 50 workers moved to the brightly colored room performed precisely the same manufacturing 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 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.

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 descendants. (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. (D) fails to take into account that people now alive have overlapping sets of ancestors. (E) fails to consider that accurate estimation of the number of people alive three thousand years ago might be impossible.

5.Essayist: The existence of a moral order in the universe—i.e., an order in which bad is always eventually punished and good rewarded—depends upon human souls being immortal. In some cultures this moral order is regarded as the result of a karma that controls how 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 describes a flaw in the essayist's 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 immortality 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 argument's conclusion is presupposed in the definition it gives of a moral order.

6.

The figure above represents a rectangular parking lot that is 30 meters by 40 meters and an attached semicircular driveway that has an outer radius of 20 meters and an inner radius of 10 meters. If the shaded region is not included, what is the area, in square meters, of the lot and driveway? (A) 1,350π (B) 1,200+400π (C) 1,200+30π (D) 1,200+200π (E) 1,200+150π

7.High Towers, a' company that occupies several office buildings, is considering installing new energy-efficient lightbulbs in its buildings. The new bulbs require less than half the electricity consumed by the conventional bulbs currently used to produce the same amount of light. The new bulbs also last considerably longer. It follows that by replacing old bulbs as they burn out with the new kind of bulb, High Towers would significantly reduce its overall lighting costs.

Which of the following, if true, most strengthens the argument given? (A) If the new bulbs are widely adopted, as seems likely, they will be produced in large enough quantities to be offered at prices comparable to those of conventional bulbs. (B) The utility that supplies High Towers with electricity offers discounted rates to its largest customers. (C) High Towers has recently signed a contract to occupy an additional small office building. (D) High Towers has begun a campaign to encourage its employees to turn off lights whenever they leave a room. (E) The company that manufactures the new bulbs has been granted a patent on the innovative technology used in the bulbs and thus has exclusive rights to manufacture them.

8.From a newspaper editorial:

Many people who are addicted to heroin will eventually attempt to overcome their addiction, principally for two reasons: 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 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. (C) legalizing the sale of heroin would increase the number of crimes committed by heroin addicts to support their addiction. (D) making heroin available legally and cheaply would make it leas likely that heroin addicts will attempt to overcome their addiction. (E) decreasing the severity of penalties for individuals who use heroin would not increase the number of new heroin addicts.

10.The chart above shows how Jeff spent his earnings for one year. How much did Jeff spend for clothing?

(1)He spent $18 during the year on tennis balls. (2)He spent $190 during the year on recreation (A) 条件(1)充分,但条件(2)不充分. (B) 条件(2)充分,但条件(1)不充分. (C) 条件(1)和(2)单独都不充分,但条件(1)和条件(2)联合起来充分. (D) 条件(1)充分,条件(2)也充分. (E) 条件(1)和条件(2)单独都不充分,条件(1)和条件(2)联合起来也不充分.

11.RESULTS OF TWO SURVEYS OF OPINIONS REGARDING THE EFFECTS OF SCIENCE ON HUMAN SOCIETY

Responses August 1991 August 1992 Mostly beneficial 25% 81% Equally harmful 37% 9% and beneficial Mostly harmful 20% 7% No opinion 18% 3% Which of the following, if true, contributes most to explaining the shift in opinions about the effects of science on human society? (A) The surveys questioned people who regularly watch prime-time television, and an innovative weekly primetime television series called "Wonders of Science" had been steadily winning viewers since its widely seen premiere in January 1992. (B) The surveys questioned college-educated adults, and a report called "The State of the Nation's Schools." published in June 1992, noted an increase in students' interest in science courses since 1982. (C) The surveys were conducted in a suburban shopping area near a company that ceased operation in April 1992 as a result of lawsuits arising from unexpected toxic effects of the company's products. (D) Both survey forms were mailed to equally large samples of the population, after returning the 1991 survey forms, respondents were sent discount coupons for food products, and after returning the 1992 survey forms, respondents were sent a pamphlet on recycling. (E) The surveys questioned first-year college students across the country, and the people who did the questioning were all research scientists.

12.

The figure above shows a cord around two circular disks. If the radii of thetwo disks are 80 centimeters and 60 centimeters, respectively, what is the total length, in centimeters, of the cord? (A) 2107π (B) 210π+280 (C) 280π (D) 280π+80 (E) 280π+280

13.Questions 4—5 are based on the following:

Any person who drops out of high school will be unemployed unless he or she finds a low-paying job or has relatives with good business connections.

14.Geographers and historians 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 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 able to present conclusive evidence. (B) Between 3,000 and 9,000 years ago, the world was warmer than it is now, and the polar landmass was presumably smaller. (C) There are only a few sixteenth-century global maps that show a continental landmass at the South Pole. (D) Most attributions of surprising accomplishments to ancient civilizations or even extraterrestrials are eventually discredited or rejected as preposterous. (E) Ancient philosophers believed that there had to be a large landmass at the South Pole to balance the northern continents and make the world symmetrical.

15.REVENUE FOR STORE X DURING WEEK 1

During week 1, revenue from eggs provided what percent of the total revenue for store X? (A) 4% (B) 5% (C) 8% (D) 20% (E) 25%

16.Bracken, a poisonous weed, is spreading and damaging much pastureland in the Northern Hemisphere. One potentially inexpensive and self-sustaining countermeasure is to introduce natural enemies of the plant; therefore, some scientists have proposed to control bracken by a release of brackeneating moths native to the Southern Hemisphere into brackeninfested areas in the Northern Hemisphere.

If the scientists' proposal for controlling bracken is adopted, which of the following is a necessary condition for its success? (A) That bracken in the Northern Hemisphere grows in approximately the same climates and soil conditions in which it grows in the Southern Hemisphere. (B) That the released moths will feed on weeds other than bracken that are native to the Northern Hemisphere. (C) That the livestock that will return to pastures now lost to bracken will develop immunities to the diseases caused by bracken. (D) That the released moths will survive in sufficient numbers to build a population large enough to reduce bracken and retard its growth. (E) That traditional methods of control, such as burning, cutting, and chemical spraying, will not become less expensive or labor-intensive than they are now.

(1)x=7 (2)t=5 (A) 条件(1)充分,但条件(2)不充分. (B) 条件(2)充分,但条件(1)不充分. (C) 条件(1)和(2)单独都不充分,但条件(1)和条件(2)联合起来充分. (D) 条件(1)充分,条件(2)也充分. (E) 条件(1)和条件(2)单独都不充分,条件(1)和条件(2)联合起来也不充分.

19.If Mark saved an average (arithmetic mean) of $80 per week for 3 consecutive weeks, how much did he save the second week?

(1)The average amount that Mark saved per week for the first 2 weeks was $60. (2)The amount that Mark saved the first week was the amount he saved the second week and the amount he saved the third Week. (A) 条件(1)充分,但条件(2)不充分. (B) 条件(2)充分,但条件(1)不充分. (C) 条件(1)和(2)单独都不充分,但条件(1)和条件(2)联合起来充分. (D) 条件(1)充分,条件(2)也充分. (E) 条件(1)和条件(2)单独都不充分,条件(1)和条件(2)联合起来也不充分.

20.Houses built during 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 automobile 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 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 used in the construction of houses, emits the pollutant formaldehyde into the house.

22.Fares on the city-run public buses 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 fares 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 city's taxpayers would relocate outside the city if public-transit fares 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 city's streets. (C) Increasing transit fares would disadvantage those residents of the city whose low incomes 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 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 usually 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 students. (B) the participation by young children in community sports teams. (C) schools' relying heavily on aerobic exercise programs to help all children become physically fit. (D) the use of a large part of a school's physical education curriculum for team sports. (E) the use of team sports in schools as an occasional activity for talented athletes.

24.The toxin produced by certain marine snails contains various proteins, one of which, when injected into mice, made mice aged two weeks or younger fall asleep and made older mice run for hiding places.

When mice are suddenly seriously threatened, very young ones react by staying perfectly still, whereas older ones run away. The facts stated above provide the strongest support for which of the following working hypotheses? (A) The reaction of mice to sudden, serious threats is triggered by a chemical produced by the body, and this chemical is similar to the protein that was injected into the mice. (B) The protein contained in snail toxin that was injected into the mice ordinarily has the primary function of protecting snails by inducing in those snails complete immobility. (C) The protein that was injected into the mice would have made the mature mice fall asleep, too, if they had been injected with larger doses. (D) Very young mice are as likely to be exposed to sudden serious threats as are older mice. (E) Very young mice are not developed enough to deal appropriately with even the stimuli that they are most likely to encounter.

25.Today's low gasoline prices make consumers willing to indulge their preference for larger cars, which consume greater amounts of gasoline as fuel. So United States automakers are unwilling to pursue the development of new fuelefficient technologies aggressively. The particular reluctance of the United States automobile industry to do, so, however, could threaten the industry's future.

Which of the following, if true, would provide the most support for the claim above about the future of the United States automobile industry? (A) A prototype fuel-efficient vehicle, built five years ago, achieves a very high 81 miles per gallon on the highway and 63 in the city, but its materials are relatively costly. (B) Small cars sold by manufacturers in the United States are more fuel efficient now than before the sudden jump in oil prices in 1973. (C) Automakers elsewhere in the world have slowed the introduction of fuel-efficient technologies but have pressed ahead with research and development of them in preparation for a predicted rise in world oil prices. (D) There are many technological opportunities for reducing the waste of energy in cars and light trucks through weight, aerodynamic drag, and braking friction. (E) The promotion of mass transit over automobiles as an alternative mode of transportation has encountered consumer resistance that is due in part to the failure of mass transit to accommodate the wide dispersal of points of origin and destinations for trips.

In the figure above, segments RS and TU represent two positions of the same ladder leaning against the side SV of a wall. The length of TV is how much greater thanthe length of RV? (1)The 1ength of TU is 10 meters. (2)The length of RV is 5 meters. (A) 条件(1)充分,但条件(2)不充分. (B) 条件(2)充分,但条件(1)不充分. (C) 条件(1)和(2)单独都不充分,但条件(1)和条件(2)联合起来充分. (D) 条件(1)充分,条件(2)也充分. (E) 条件(1)和条件(2)单独都不充分,条件(1)和条件(2)联合起来也不充分.

27.An economist concluded that Kregg Company deliberately discriminated against people with a history of union affiliation in hiring workers for its new plant. The economist's evidence is that, of the 1,500 people hired to work at the new plant, only 100 had ever belonged to a labor union, whereas in Kregg Company's older plants, a much higher proportion of workers have a history of union affiliation.

Which of the following is an assumption on which the economist's argument depends? (A) None of the people with a history of union affiliation who were hired to work at the new plant were union organizers. (B) Applicants for jobs at the new plant were not asked by Kregg's recruiters whether they had every belonged to a labor union. (C) In the plants of some of Kregg's competitors, the workforce consists predominantly of union members. (D) The company believes that the cost of running the new plant will be lower if labor unions are not represented in the workforce. (E) The pool of potential candidates for jobs at the new plant included some people, in addition to those Kregg hired, with a history of union affiliation.

28.In the course of her researches, a historian recently found two documents mentioning the same person, Erich Schnitzler. One, dated May 3, 1739, is a record of Schnitzler's arrest for peddling without a license. The second, undated, is a statement by Schnitzler asserting that he has been peddling off and on for 20 years.

The facts above best support which of the following conclusions? (A) Schnitzler started peddling around 1719. (B) Schnitzler was arrested repeatedly for peddling. (C) The undated document was written before 1765. (D) The arrest record was written after the undated document. (E) The arrest record provides better evidence that Schnitzler peddled than does the undated document.

30.Grazing livestock on public land in the western United States is not causing widespread environmental damage in the region, since if it were, the condition of that land would not be improving. However, only 14 percent of public land in the area today is considered to have inadequate vegetation cover and, therefore, to be in poor condition, while in the 1930's, 36 percent had inadequate vegetation cover.

Which of the following, if true, most seriously weakens the argument above? (A) In the western United States, private land is typically more lush than public land, and cattle that graze on private land can be fattened more quickly. (B) Since the 1930's, recreational users of public land in the western United States have caused more environmental damage than have the cattle grazing there. (C) During the 1930's, an unusually destructive drought prevailed throughout the region where most public lands in the western United States are located. (D) Ranchers who use public land in the western United States pay only a fraction of what is paid by those who lease comparable private land for grazing. (E) The amount of land purchased by the United States government since the 1930's is relatively insignificant.

31.The large amounts of carbon dioxide now being released into the atmosphere by the burning of fossil fuels will not, in fact, result in a greenhouse effectan increase in average global temperatures. Since plants use carbon dioxide in larger quantities if the supply is increased, they are able to grow larger and multiply more vigorously, and atmospheric carbon dioxide concentrations will eventually become stable.

Which of the following, if true, would most seriously weaken the conclusion that a greenhouse effect will not result from the current release of large amounts of carbon dioxide into the atmosphere? (A) The expected rise in average global temperatures has not yet been observed. (B) Ocean waters absorb carbon dioxide at a greater rate when the atmospheric concentration of carbon dioxide is higher. (C) Since the beginning of the Industrial Revolution, increased atmospheric concentrations of carbon dioxide have resulted in improved agricultural productivity. (D) When plants decay, they produce methane, another gas that can have a marked greenhouse effect. (E) The fact that carbon dioxide levels have risen and fallen many times in the Earth's history suggests that there is some biological process that can reverse the greenhouse effect.

32.

33.Pam and Ed are in a line to purchase tickets. How many people are in the line?

(1)There are 20 people behind Pare and 30 people in front of Ed. (2)There are 5 people between Pam and Ed. (A) 条件(1)充分,但条件(2)不充分. (B) 条件(2)充分,但条件(1)不充分. (C) 条件(1)和(2)单独都不充分,但条件(1)和条件(2)联合起来充分. (D) 条件(1)充分,条件(2)也充分. (E) 条件(1)和条件(2)单独都不充分,条件(1)和条件(2)联合起来也不充分.

34.In opposing the 1970 Clean Air Act, the United States automobile industry argued that meeting the act's standards for automobile emissions was neither economically feasible nor environmentally necessary. However, the catalytic converter, invented in 1967, enable automakers to meet the 1970 standards efficiently. Currently, automakers are lobbying against the government's attempt to pass legislation that would tighten restrictions on automobile emissions. The automakers contend that these new restrictions would be overly expensive and unnecessary to efforts to curb air pollution. Clearly, the automobile industry's position should not be heeded.

Which one of the following, if true, lends the most support to the automakers' current position? (A) The more stringent the legislation restricting emissions becomes, the more difficult it becomes for automakers to provide the required technology economically. (B) Emissions-restriction technology can often be engineered so as to avoid reducing the efficiency with which an automobile uses fuel. (C) Not every new piece of legislation restricting emissions requires new automotive technology in order for automakers to comply with it. (D) The more automobiles there are on the road, the more stringent emission restrictions must be to prevent increased overall air pollution. (E) Unless forced to do so by the government, automakers rarely make changes in automotive technology that is not related to profitability.

35.What is the 1st term in sequence S?

(1)The 3 rd term in S is 2. (2)The 2 nd term in S is twice the 1 st, and the 3 rd term is three times the 2 nd. (A) 条件(1)充分,但条件(2)不充分. (B) 条件(2)充分,但条件(1)不充分. (C) 条件(1)和(2)单独都不充分,但条件(1)和条件(2)联合起来充分. (D) 条件(1)充分,条件(2)也充分. (E) 条件(1)和条件(2)单独都不充分,条件(1)和条件(2)联合起来也不充分.

36.In the United States, vacationers account for more than half of all visitors to what are technically called "pure aquariums" but for fewer than one quarter of all visitors to zoos, which usually include a "zoo aquarium" of relatively modest scope.

Which of the following, if true, most helps to account for the difference described above between visitors to zoos and visitors to pure aquariums? (A) In cities that have both a zoo and a pure aquarium, local residents are twice as likely to visit the aquarium as they are to visit the zoo. (B) Virtually all large metropolitan areas have zoos, whereas only a few large metropolitan areas have pure aquariums. (C) Over the last ten years, newly constructed pure aquariums have outnumbered newly established zoos by a factor of two to one. (D) People who visit a zoo in a given year are two times more likely to visit a pure aquarium that year than are people who do not visit a zoo. (E) The zoo aquariums of zoos that are in the same city as a pure aquarium tend to be smaller than the aquariums of zoos that have no pure aquarium nearby.

37.New employees of Ace Industries are complaining about discomfort caused by excessive noise inside Ace's factory. Experienced Ace factory employees, however, do not suffer any such discomfort. Although Ace accepts responsibility for the health of its employees, it has decided not to issue earplugs to new employees. Ace reasoned that the new employees would also become accustomed to the noise without using earplugs.

Which of the following, if true, indicates a flaw in Ace's decision not to issue earplugs to new employees? (A) Because the noise in Ace's factory is absorbed by soundproof walls, it cannot be heard by Ace executives in their offices. (B) Many of the new employees interviewed said they would not wear earplugs on the job. (C) Issuing earplugs to all new employees would be a less effective method of reducing employees' exposure to noise than altering the machinery to be less noisy would be. (D) The experienced employees' lack of discomfort is attributable to hearing loss caused by the factory noise. (E) The machines in Ace's factory have not become any noisier since the experienced workers were originally hired.

38.

In the table above, what is the least number of table entries that are needed to show the mileage between each city and each of the other five cities? (A) 15 (B) 21 (C) 25 (D) 30 (E) 36

39.The Wheat Farmers Alliance, a political action committee, attracts 70 percent of its contributors from an advertisement requesting contributions placed only in the September, October, and November issues of the Grange Report, a monthly newsletter for wheat farmers. The president of the Wheat Farmers Alliance, to increase the number of contributors, decides to advertise in each of the monthly issues of the Grange Report. She expects that, as a result of the additional Grange Report advertisements, the number of contributors will be increased to at least double the present number.

Which of the following, if tree, would most strongly support the president's expectation? (A) The September, October, and November advertisements were noticed by fewer than one-third of those readers of the Grange Report' who would be willing to contribute to the Wheat Farmers Alliance. (B) Wheat farmers traditionally repay their bank loans in late summer after the winter wheat crop has been harvested and sold. (C) The majority of the readers of the Grange Report with a great enough interest in the Wheat Farmers Alliance to contribute have already responded to the advertisements. (D) Most of those who contribute to the Wheat Farmers Alliance in the course of a year do so in response to advertisements in the Grange Report. (E) The total number of readers of the Grange Report is stable from year to year.

40.In recent years the climate has been generally cool in northern Asia. But during periods when the average daily temperature and humidity in northern Asia were slightly higher than their normal levels the yields of most crops grown there increased significantly. In the next century, the increased average daily temperature and humidity attained during those periods are expected to become the norm. Yet scientists predict that the yearly yields of most of the region's crops will decrease during the next century.

Which one of the following, if true, most helps to resolve the apparent paradox in the information above? (A) Crop yields in southern Asia are expected to remain constant even after the average daily temperature and humidity there increase from recent levels. (B) Any increases in temperature and humidity would be accompanied by higher levels of atmospheric carbon dioxide, which is vital to plant respiration. (C) The climate in northern Asia has generally been too cool and dry in recent years for populations of many crop insect pests to become established. (D) In many parts of Asia, the increased annual precipitation that would result from warmer and wetter climates would cause most edible plant species to flourish. (E) The recent climate of northern Asia prevents many crops from being farmed there during the winter.

41.It was long thought that a now-rare disease of the joints, alkaptonuria, was epidemic in Egypt 2,500 years ago. Evidence came from the high proportion of mummies from that period showing symptoms of the disease. Recently, however, chemical analyses of skeletons have led scientists to propose that the joint damage was actually caused by chemicals used by Egyptian embalmers.

Which of the following, if true, would additionally weaken the traditional view that alkaptonuria afflicted many Egyptians 2,500 years ago? (A) X-rays of the mummies showed shadows that clearly suggested joint damage, and recent inspection of the skeletons has confirmed that hypothesis. (B) Although alkaptonuria is a disease that can be inherited, it did not appear in the descendants of the Egyptian population in which the symptoms were found. (C) Egyptian embalming methods were highly secret, and scientists are still not certain of the nature of some of the chemicals that were used. (D) Possible evidence of alkaptonuria has been pointed out in pictures representing the human figure found on artifacts left by other Middle Eastern cultures of that period.

46.During the nineteenth century, Britain's urban population increased as its rural population diminished. A historian theorizes that, rather than industrialization's being the cause, this change resulted from a series of migrations to urban areas, each occasioned by a depression in the agrarian economy. To test this hypothesis, the historian will compare economic data with population census data.

The historian's hypothesis would be most strongly supported if which of the following were found to be true? (A) The periods of greatest growth in the industrial economy were associated with a relatively rapid decline in the rural population. (B) The periods of greatest weakness in the agrarian economy were associated with relatively slow growth in the population as a whole. (C) Periods when the agrarian economy was comparatively strong and the industrial economy comparatively weak were associated with a particularly rapid decline in the rural population. (D) Periods when the agrarian and industrial economies were both strong were associated with particularly rapid growth in the urban population. (E) The periods of greatest strength in the agrarian economy were associated with relatively slow growth in the urban population.

48.A certain type of dinnerware made in Ganandia contains lead. Lead can leach into acidic foods, and Ganandians tend to eat highly acidic foods. However, the extreme rarity of lead poisoning in Ganandia indicates that the dinnerware does not contain dangerous amounts of lead.

Which of the following, if true, most seriously weakens the argument above? (A) The dinnerware is produced exclusively for sale outside Ganandia. (B) Ganandian foods typically are much more acidic than foods anywhere else in the world. (C) The only source of lead poisoning in Ganandia is lead that has leached into food. (D) Most people who use the dinnerware are not aware that it contains lead. (E) Acidic foods can leach lead from dinnerware even if that dinnerware has a protective coating.

49.In the United States, injuries to passengers involved in automobile accidents are typically more severe than in Europe, where laws require a different kind of safety belt. It is clear from this that the United States needs to adopt more stringent standards for safety belt design to protect automobile passengers better.

Each of the following, if true, weakens the argument above EXCEPT: (A) Europeans are more likely to wear safety belts than are people in the United States. (B) Unlike United States drivers, European drivers receive training in how best to react in the event of an accident to minimize injuries to themselves and to their passengers. (C) Cars built for the European market tend to have more sturdy construction than do cars built for the United States market. (D) Automobile passengers in the United States have a greater statistical chance of being involved in an accident than do passengers in Europe. (E) States that have recently begun requiring the European safety belt have experienced no reduction in the average severity of injuries suffered by passengers in automobile accidents.

50.On turning 65 years old, everyone living in the town of Malton becomes eligible to receive a card that guarantees discounts on most goods and services sold in the town. Census records for 1990 show that 2,450 inhabitants of Malton turned 64 in that year. Yet, in 1991 over 3,000 people applied for and properly received discount cards. So clearly some of Malton's population growth between 1990 and 1992 must be attributable to migration into the city by people in their mid-60's.

Which of the following is an assumption on which the argument depends? (A) The town of Malton has no complete census records for 1991. (B) The overall size of the population of Malton grew by over 500 during 1990. (C) Fewer people applied for and received discount cards in 1991 than did so in 1992. (D) Among the people 65 years old or older who moved into Malton in 1991, there was no one who did not apply for a discount card. (E) In general, people who applied for and received discount cards in 1991 first became eligible to do so in that year.
