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)

5.Government-subsidized insurance available to homeowners makes it feasible for anyone to build a house on a section of coastline regularly struck by hurricanes. Each major storm causes billions of dollars worth of damage in such coastal areas, after which owners who have insurance are able to collect an amount of money sufficient to recoup a high percentage of their losses.

The passage provides the most support for an argument against a government bill proposing (A) that power companies be required to bury power lines in areas of the coastline regularly struck by hurricanes. (B) an increase in funding of weather service programs that provide a hurricane watch and warning system for coastal areas. (C) renewal of federal funding for emergency life-support programs in hurricane-stricken areas. (D) establishment of an agency committed to managing coastal lands in ecologically responsible ways. (E) establishment of a contingency fund protecting owners of uninsured houses in the coastal areas from catastrophic losses due to the hurricane damage.

6.If n is an integer between 2 and 100 and if n is also the square of an integer, what is the value of n?

(1)n is the cube of an integer. (2)n is even. (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.

7.Most of Earth's surface is ocean. The ocean floor is inaccessible for extensive research without equipment of greater technological sophistication than is currently available. It must therefore be true that scientists know less about the ocean floor environment than about almost any other environment on Earth.

Which of the following, if true, provides the most support for the conclusion? (A) Many mountain ranges lie entirely beneath the ocean surface, yet new underwater surveying equipment has produced three-dimensional charts of them that are as accurate as those available for mountain ranges on land. (B) Strong water currents circulate on the ocean floor, but the general pattern of their movement is not so well understood as is the pattern of air currents that circulate over land. (C) In contrast to most land environments, temperature conditions at the ocean floor are generally stable and uniform, since sunlight does not penetrate far below the ocean surface. (D) Very few people have seen detailed maps of extended regions of the ocean floor, even though such maps are available in almost all large libraries. (E) Animals living on the ocean floor must be able to withstand water pressure that is far greater than the atmospheric pressure with which land animals live.

11.Grammarians have for years condemned as ungrammatical the English phrase "between you and I," insisting that the correct phrasing is "between you and me," with the objective case after a preposition. Such condemnations, however, are obviously unfounded, because Shakespeare himself, in The Merchant of Venice, wrote, "All debts are cleared between you and I."

Which of the following, if true, most seriously weakens the argument above? (A) In his plays, Shakespeare intentionally had some of his characters use phrases he considered ungrammatical. (B) The phrase "between you and I" appears infrequently in Shakespeare's writings. (C) The more modern an English word or phrase, the less likely that modem grammarians will consider it acceptable for formal usage. (D) Many modern speakers of English sometimes say "between you and I" and sometimes say "between you and me." (E) Most native speakers of English who choose to say "between you and I" do so because they know that Shakespeare used that phrase.

12.When cut, the synthetic material fiberglass, like asbestos, releases microscopic fibers into the air. It is known that people who inhale asbestos fibers suffer impairment of lung function. A study of 300 factory workers who regularly cut fiberglass showed that their lung capacity is, on average, only 90 percent of that of a comparable group of people who do not cut fiberglass.

The statements above, if tree, most strongly support which of the following hypotheses? (A) People who work with fiberglass are likely also to work with asbestos. (B) Fiberglass fibers impair lung function in people who inhale them. (C) Fiberglass releases as many fibers into the air when cut as does asbestos. (D) Coarse fibers do not impair lung function in people who inhale them. (E) If uncut, fiberglass poses no health risk to people who work with it.

13.Although it is assumed that peacocks' magnificent tails function essentially to attract peahens, no one knows why it should be magnificent tails that give a competitive advantage in securing mates. One explanation is that peahens are more likely to mate with peacocks with magnificent tails than with peacocks that lack magnificent tails.

Which of the following is an error of reasoning exemplified by the explanation? (A) Attributing to animals qualities that are characteristically human. (B) Extending a conclusion that is true of only one species of a genus to all species of the genus. (C) Offering as an explanation a hypothesis that in principle can be neither verified nor proved false. (D) Offering the phenomenon that is to be explained as the explanation of that phenomenon. (E) Assuming without warrant that peacocks with magnificent tails are likely to have other features strongly attractive to peahens.

14.A rectangle is defined to be "silver" if and only if the ratio of its length to its width is2 to 1. If rectangle S is silver, is rectangle R silver?

(1)R has the same area as S. (2)The ratio of one side of R to one side of S is 2 to 1. (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.

15.

In the figure above, QRS is a straight line and 1ine TR bisects ∠PRS. Is it true that lines TR and PQ are parallel? (1)PQ=PR (2)QR=PR (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.

16.Hastings' contracture is a disorder of the connective tissue in one or both hands, most commonly causing loss of mobility. A survey of thousands of medical-insurance claims found that over 30 percent of people who had one hand operated on for Hastings' contracture underwent surgery a second time for this disorder within three years. Clearly, therefore, a single surgical treatment of Hastings' contracture is often ineffective at providing long-term correction of the disorder.

Which of the following, if true, most seriously weakens the argument? (A) The medical-insurance claims did not specify whether the surgery was on the patient's right or left hand. (B) The surgical techniques used to treat Hastings' contracture are identical to those used successfully to treat certain work-related injuries to the hand. (C) A separate survey found that 90 percent of patients operated on for Hastings' contracture report increased hand mobility within one month after the surgery. (D) All of the patients in the survey were required by their insurance companies to seek a second opinion from a qualified surgeon before undergoing the operation. (E) Many people who have Hastings' contracture choose to tolerate its effects rather than undergo the risks of surgery.

17.Despite the approach of winter, oil prices to industrial customers are exceptionally low this year and likely to remain so. Therefore, unless the winter is especially severe, the price of natural gas to industrial customers is also likely to remain low.

Which of the following, if true, provides the most support for the conclusion above? (A) Long-term weather forecasts predict a mild winter. (B) The industrial users who consume most natural gas can quickly and cheaply switch to using oil instead. (C) The largest sources of supply for both oil and natural gas are in subtropical regions unlikely to be affected by winter weather. (D) The fuel requirements of industrial users of natural gas are not seriously affected by the weather. (E) Oil distribution is more likely to be affected by severe winter weather than is the distribution of natural gas.

19.Hardin argued that grazing land held in common (that is, open to any user) would always be used less carefully than private grazing land. Each rancher would be tempted to overuse common land because the benefits would accrue to the individual, while the costs of reduced land quality that results from overuse would be spread among all users. But a study comparing 217 million acres of common grazing land with 433 million acres of private grazing land showed that the common land was in better condition.

Which of the following, if true and known by the ranchers, would best help explain the results of the study? (A) With private grazing land, both the costs and the benefits of overuse fall to the individual user. (B) The cost in reduced land quality that is attributable to any individual user is less easily measured with common land than it is with private land. (C) An individual who overuses common grazing land might be able to achieve higher returns than other users can, with the result that he or she would obtain a competitive advantage. (D) If one user of common land overuses it even slightly, the other users are likely to do so even more, with the consequence that the costs to each user outweigh the benefits. (E) There are more acres of grazing land held privately than there are held in common.

20.What is the remainder when the positive integer x is divided by 2?

(1)x is an odd integer. (2)x is a multiple of 3. (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.

21.Corporate officers and directors commonly buy and sell, for their own portfolios, stock in their own corporations. Generally, when the ratio of such inside sales to inside purchases falls below 2 to 1 for a given stock, a rise in stock prices is imminent. In recent days, while the price of MEGA Corporation stock has been falling, the corporation's officers and directors have bought up to nine times as much of it as they have sold.

The facts above best support which of the following predictions? (A) The imbalance between inside purchases and inside sales of MEGA stock will grow even further. (B) Inside purchases of MEGA stock are about to cease abruptly. (C) The price of MEGA stock will soon begin to go up. (D) The price of MEGA stock will continue to drop, but less rapidly. (E) The majority of MEGA stock will soon be owned by MEGA's own officers and directors.

22.Mayor: Four years ago when we reorganized the city police department in order to save money, critics claimed that the reorganization would make the police less responsive to citizens and would thus lead to more crime. The police have compiled theft statistics from the years following the reorganization that show that the critics were wrong. There was an overall decrease in reports of thefts of all kinds, including small thefts.

Which of the following, if true, most seriously challenges the mayor's argument? (A) When city police are perceived as unresponsive, victims of theft are less likely to report thefts to the police. (B) The mayor's critics generally agree that police statistics concerning crime reports provide the most reliable available data on crime rates. (C) In other cities where police departments have been similarly reorganized, the numbers of reported thefts have generally risen following reorganization. (D) The mayor's reorganization of the police department failed to save as much money as it was intended to save. (E) During the four years immediately preceding the reorganization, reports of all types of theft had been rising steadily in comparison to reports of other crimes.

23.Ethicist: A society is just when and only when first, each person has an equal right to basic liberties and second, inequalities in the distribution of income and wealth are not tolerated unless these inequalities are to everyone's advantage and are attached to jobs open to everyone.

Which one of the following judgments most closely conforms to the principle described above? (A) Society S guarantees everyone equal right to basic liberties, while allowing inequalities in the distribution of income and wealth that are to the advantage of everyone. Further, the jobs to which these inequalities are attached are open to most people. Thus, society S is just. (B) Society S gives everyone an equal right to basic liberties, but at the expense of creating inequalities in the distribution of income and wealth. Thus, society S is not just. (C) Society S allows inequalities in the distribution of income and wealth, although everyone benefits and these inequalities are attached to jobs that are open to everyone. Thus, society S is just. (D) Society S distributes income and wealth to everyone equally, but at the expense of creating inequalities in the right to basic liberties. Thus, society S is not just. (E) Society S gives everyone an equal right to basic liberties, and although there is an inequality in the distribution of income and wealth, the jobs to which these inequalities are attached are open to all. Thus, society S is just.

24.Book Review: When I read a novel set in a city I know well, I must see that the writer knows the city at least as well as I do if I am to take that writer seriously. If the writer is faking, I know immediately and do not trust that writer.

When a novelist demonstrates the required knowledge, I trust the storyteller, so. I trust the tale. This trust increases my enjoyment of a good novel. Peter Lee's second novel is set in San Francisco. In this novel, as in his first, Lee passes my test with flying colors. Which one of the following can be properly inferred from the passage? (A) The book reviewer enjoys virtually any novel written by a novelist whom she trusts. (B) If the book reviewer trusts the novelist as a storyteller, the novel in question must be set in a city the book reviewer knows well. (C) Peter Lee's first novel was set in San Francisco. (D) The book reviewer does not trust any novel set in a city that she does not know well. (E) The book reviewer does not believe that she knows San Francisco better than Peter Lee does.

25.

In the diagram above, points A, B, C, D, and E represent the five teams in a certain league in which each team must play each of the other teams exactly once. The segments connecting pairs of points indicate that the two corresponding teams have already played their game. The arrows on the segments point to the teams that lost; the lack of an arrow on a segment indicates that the game ended in a tie. After all games have been played, which of the following could NOT be the percent of games played that ended in a tie? (A) 10% (B) 20% (C) 30% (D) 40% (E) 50%

26.When soil is plowed in the spring, pigweed seeds that have been buried in the soil all winter are churned up to the surface and redeposited just under the surface. The brief exposure of the seeds to sunlight stimulates receptors, which have become highly sensitive to sunlight during the months the seeds were buried in the soil, and the stimulated receptors trigger germination. Without the prolonged darkness, followed by exposure to sunlight, the seeds do not germinate.

The statements above, if true, most strongly support which one of the following statements about a field that will be plowed in the spring and in which pigweed seeds have been buried in the soil all winter? (A) Fewer pigweed plants will grow in the field if it is plowed only at night than if it is plowed during the day. (B) Fewer pigweed plants will grow in the field if it is not plowed at all than if it is plowed only at night. (C) Fewer pigweed plants will grow in the field if it is plowed just before sunrise than if it is plowed just after sunset. (D) The pigweed seeds that are churned up to the surface of the soil during the plowing will not germinate unless they are redeposited under the surface of the soil. (E) All of the pigweed seeds that are already on the surface of the soil before the field is plowed will germinate.

If a customer makes exactly one selection from each of the five categories shown in the table above, what is the greatest possible number of different ice cream sundaes that a customer can create?

(A) 9,600 (B) 4,800 (C) 2,400 (D) 800 (E) 400

28.On Saturday Melvin suggested that Jerome take the following week off from work and accompany him on a trip to the mountains. Jerome refused, claiming that he could not afford the cost of the trip added to the wages he would forfeit by taking off without notice. It is clear, however, that cost cannot be the real reason, for Jerome's unwillingness to go with Melvin to the mountains, since he makes the same excuse every time. Melvin asks him to take an unscheduled vacation regardless of where Melvin propose to go.

The reasoning is most vulnerable to which one of the following criticisms? (A) It attempts to forestall "an attack on Melvin's behavior by focusing attention on the behavior of Jerome. (B) It fails to establish that Melvin could no more afford to take an unscheduled vacation trip to the mountains than could Jerome. (C) It overlooks the possibility that Jerome, unlike Melvin, prefers vacations that have been planned far in advance. (D) It assumes that if Jerome's professed reason is not his only reason, then it cannot be a real reason for Jerome at all. (E) It does not examine the possibility that Jerome's behavior is adequately explained by the reason he gives for it.

29.Defendants who can afford expensive private defense lawyers have a lower conviction rate than those who rely on court-appointed public defenders. This explains why criminals who commit lucrative crimes like embezzlement or insider trading are more successful at avoiding conviction than are street criminals.

The explanation offered above would be more persuasive if which one of the following were true? (A) Many street crimes, such as drug dealing, are extremely lucrative and those committing them can afford expensive private lawyers. (B) Most prosecutors are not competent to handle cases involving highly technical financial evidence and have more success in prosecuting cases of robbery or simple assault. (C) The number of criminals convicted of street crimes is far greater than the number of criminals convicted of embezzlement or insider trading. (D) The percentage of defendants who actually committed the crimes of which they are accused is no greater for publicly defended than for privately defended defendants. (E) Juries, out of sympathy for the victims of crimes, are much more likely to convict defendants accused of violent crimes than they are to convict defendants accused of "victimless" crimes or crimes against property.

30.Although compact cars make up only 38 percent of the vehicles in traffic, 48 percent of the cars that are followed too closely ("tailgated") are compact. On the other hand, fewer than 27 percent of the cars tailgated are middle-sized, even though middle-sized cars make up 31 percent of the vehicles in traffic.

Which of the following, if true, most contributes to an explanation for the phenomenon described above? (A) The shape of compact cars makes it easy for a tailgater to see far enough ahead around such cars to minimize the chances of a rear-end collision. (B) Middle-sized cars, owned by families with children and pets, are likely to have bumper stickers that are so interesting to read that tailgaters stay behind such cars longer. (C) Compact cars sometimes have superior engines that allow them to pass middle-sized cars on the highway easily. (D) The percentage of cars on the highway that are middlesized has been steadily decreasing over the last decade. (E) Compact cars are often driven by fast drivers.

31.There is strong evidence that the cause of migraines (severe recurrent headaches) is not psychological but instead is purely physiological. Yet several studies have found that people being professionally treated for migraines rate higher on a standard psychological scale of anxiety than do people not being professionally treated for migraines.

Which one of the following, if true, most helps to resolve the apparent discrepancy in the information above? (A) People who have migraine headaches tend to have relatives who alto have migraine headaches. (B) People who have migraine headaches often suffer these headaches when under emotional stress. (C) People who rate higher on the standard psychological scale of anxiety are more likely to seek professional treatment than are people who rate lower on the scale. (D) Of the many studies done on the cause of migraine headaches, most of those that suggest that psychological factors such as anxiety cause migraines have been widely publicized. (E) Most people who have migraines and who seek professional treatment remain in treatment until they stop having migraines, whether their doctors consider the cause to be physiological or psychological.

32.The only purpose for which a particular type of tape is needed is to hold certain surgical wounds closed for ten days— the maximum time such wounds need tape. Newtape is a new brand of this type of tape. Newtape's salespeople claim that Newtape will improve healing because Newtape adheres twice as long as the currently used tape does.

Which of the following statements, if true, would most seriously call into question the claim made by Newtape's salespeople? (A) Most surgical wounds take about ten days to heal. (B) Most surgical tape is purchased by hospitals and clinics rather than by individual surgeons. (C) The currently used tape's adhesiveness is more than sufficient to hold wounds closed for ten days. (D) Neither Newtape nor the currently used tape adheres well to skin that has not been cleaned. (E) Newtape's adhesion to skin that has been coated with a special chemical preparation is only half as good as the currently used tape's adhesion to such coated skin.

33.More than a year ago, the city announced that police would crack down on illegally parked cars and that resources would be diverted from writing speeding tickets to ticketing illegally parked cars. But no crackdown has taken place. The police chief claims that resources have had to be diverted from writing speeding tickets to combating the city's staggering drug problem. Yet the police are still writing as many speeding tickets as ever. Therefore, the excuse about resources being tied up in fighting drug-related crime simply is not true.

The conclusion in the passage depends on the assumption that (A) every member of the police force is qualified to work on combating the city's drug problem. (B) drug-related crime is not as serious a problem for the city as the police chief claims it is. (C) writing speeding tickets should be as important a priority for the city as combating drug-related crime. (D) the police could be cracking down on illegally parked cars and combating the drug problem without having to reduce writing speeding tickets. (E) the police cannot continue writing as many speeding tickets as ever while diverting resources to combating drugrelated crime.

34.The nuclear polyhedrosis virus helps control gypsy moth populations by killing the moth's larvae. The virus is always present in the larvae, but only every sixth or seventh year does the virus seriously decimate the number of larvae, thereby drastically setting back the gypsy moth population. Scientists believe that the virus, ordinarily latent, is triggered only when the larvae experience biological stress.

If the scientists mentioned above are correct, it can be inferred that the decimation of gypsy moth larvae populations by the nuclear polyhedrosis virus would be most likely to be triggered by which of the following conditions? (A) A shift from drought conditions to normal precipitation in areas infested by gypsy moths. (B) The escalating stress of defoliation sustained by trees at tacked by gypsy moths for the second consecutive year. (C) Predation on larvae of all kinds by parasitic wasps and flies. (D) Starvation of the gypsy moth larvae as a result of overpopulation. (E) Spraying of areas infested by gypsy moths with laboratory-raised nuclear polyhedrosis virus.

36.Proposals for extending the United States school year to bring it more in line with its European and Japanese counterparts are often met with the objection that curtailing the schools' three-month summer vacation would violate an established United States tradition dating from the nineteenth century. However, this object misses its mark. True, in the nineteenth century the majority of schools closed for three months every summer, but only because they were in rural areas where successful harvests depended on children's labor. If any policy could be justified by those appeals to tradition, it would be the policy of determining the length of the school year according to the needs of the economy.

The argument counters the objection by (A) providing evidence to show that the objection relies on a misunderstanding about the amount of time each year United States schools traditionally have been closed. (B) calling into question the relevance of information about historical practices to current disputes about proposed social change. (C) arguing for an alternative understanding of the nature of the United States tradition regarding the length of the school year. (D) showing that those who oppose extending the school year have no genuine concern for tradition. (E) demonstrating that tradition justifies bringing the United States school year in line with that of the rest of the industrialized world.

37.X-ray examination of a recently discovered painting — judged by some authorities to be a self-portrait by Vincent van Gogh — revealed an underimage of a woman's face. Either van Gogh or another painter covered the first painting with the portrait now seen on the surface of the canvas. Because the face of the woman in the underimage also appears on canvases van Gogh is known to have painted, the surface painting must be an authentic self-portrait by van Gogh.

The conclusion above is properly drawn if which of the following is assumed? (A) If a canvas already bears a painted image produced by an artist, a second artist who uses the canvas to produce a new painting tends to be influenced by the style of the first artist. (B) Many painted canvases that can be reliably attributed to van Gogh contain underimages of subjects that appear on at least one other canvas that van Gogh is known to have painted. (C) Any painted canvas incorrectly attributed to van Gogh would not contain an underimage of a subject that appears in authentic paintings by that artist. (D) A painted canvas cannot be reliably attributed to an artist unless the authenticity of any underimage that painting might contain can be reliably attributed to the artist. (E) A painted canvas cannot be reliably attributed to a particular artist unless a reliable X-ray examination of the painting is performed.

39.Two suits of battle armor worn by King Henry VIII were discovered, one from the beginning of his reign in 1510 and the other from 1540. Although both suits of armor were made for Henry VIII, the 1540 suit of armor was 40 pounds heavier than the 1510 suit of armor.

Which of the following, if true, contributes LEAST to an explanation of the discrepancy described above? (A) Henry, although slim at the beginning of his reign, developed a bulky figure because of massive weight gain. (B) During his reign Henry increased his arsenal of weapons because, despite his popularity in 1510, by 1540 the English populace was becoming disenchanted with his rule. (C) Although the style of armor was plain and severe in the beginning of Henry's reign, he started the fashion of decorating armor with heavy and elaborate metal pieces because of his love for ornamentation. (D) Henry ascended the throne while still an adolescent and grew three inches during his first five years as king. (E) Because of the improved design of battle weaponry during the 1530's, armor was given a multilayered design so that the sharper and stronger weapons could not pierce it.

41.In the aftermath of a worldwide stock-market crash, Country T claimed that the severity of the stock-market crash it experienced resulted from the accelerated process of denationalization many of its industries underwent shortly before the crash.

Which of the following, if it could be carried out, would be most useful in an evaluation of Country T's assessment of the causes of the severity of its stock-market crash? (A) Calculating the average loss experienced by individual traders in Country T during the crash. (B) Using economic theory to predict the most likely date of the next crash in Country T. (C) Comparing the total number of shares sold during the worst days of the crash in Country T to the total number of shares sold in Country T just prior to the crash. (D) Comparing the severity of the crash in Country T to the severity of the crash in countries otherwise economically similar to Country T that have not experienced recent denationalization. (E) Comparing the long-term effects of the crash on the purchasing power of the currency of Country T to the immediate, more severe short-term effects of the crash on the purchasing power of the currency of Country T.

42.During the last hunting season, twice as many people were hit by cars while walking on public sidewalks as were hurt in hunting accidents in the woods. Therefore, during the last hunting season, people were safer in the woods than they were while walking on public sidewalks.

In evaluating the argument above, it would be most important to know (A) the likelihood that during the next hunting season fewer people will be hurt in hunting accidents in the woods than were hurt during the last hunting season. (B) the ratio during last hunting season of people who walked on public sidewalks to people who were in the woods. (C) how many of the people hurt in hunting accidents during the last hunting season had been hurt in similar accidents in the past. (D) how many of the accidents could have been avoided if the drivers of the cars or the hunters who fired the guns had been more careful. (E) how many people, on average, are hurt in hunting accidents in the woods when it is not hunting season.

43.Car telephones have become increasingly popular because they permit people to make or receive business calls while driving. As an additional benefit, motorists can quickly call for help in the event of an accident or breakdown. Nevertheless, car telephones should be prohibited because their use causes hazardous driving.

It can be concluded from the statements above that the author is committed to the troth of which of the following statements? (A) The increasing popularity of car telephones is due primarily to the fact that they permit motorists to call for help in the event of an accident. (B) The reason that the use of car telephones causes hazardous driving is that while dialing calls drivers cannot keep both hands on the wheel. (C) The advantages afforded by car telephones do not outweigh the risks of hazardous driving created by them. (D) In order to dial or receive telephone calls, drivers must momentarily take their eyes off the road, and this practice is hazardous. (E) The ability to use car telephones to call for help is a more important advantage than the ability to use these phones to engage in business calls.

44.Town T has 20,000 residents, 60 percent of whom are female. What percent of the residents were born in Town T?

(1)The number of female residents who were born in Town T is twice the number of male residents who were not born in Town T. (2)The number of female residents who were not born in Town T is twice the number of male residents who were born in Town T. (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.

45.149 people were aboard Flight 222 when it arrived at Los Angeles from New York City with Chicago as the only intermediate stop. How many people first boarded the flight in Chicago?

(1)170 people were aboard the flight when it left New York City. (2)23 people from the flight deplaned in Chicago and did not reboard. (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.

47.Psychologists today recognize childhood as a separate stage of life which can only be understood in its own terms, and they wonder why the Western world took so long to see the folly of regarding children simply as small, inadequately socialized adults. Most psychologists, however, persist in regarding people 70 to 90 years old as though they were 35 years old who just happen to have white hair and extra leisure time. But old age is as fundamentally different from young adulthood and middle age as childhood is—a fact attested to by the organization of modern social and economic life. Surely it is time, therefore, to acknowledge that serious research into the unique psychology of advanced age has become indispensable.

Which one of the following principles, if established, would provide the strongest backing for the argument? (A) Whenever current psychological practice conflicts with traditional attitudes toward people, those traditional attitudes should be changed to bring them in line with current psychological practice.

48.Many state legislatures are considering proposals to the effect that certain policies should be determined not by the legislature itself but by public referenda in which every voter can take part.

49.In malaria-infested areas, many children tend to suffer several bouts of malaria before becoming immune to the disease.

Which of the following, if true, most seriously undermines the explanatory hypothesis? (A) Immediately after a child has suffered a bout of malaria, the child's caregivers tend to go to great lengths in taking precautions to prevent another infection, but this level of attention is not sustained. (B) Malaria is spread from person to person by mosquitoes, and mosquitoes have become increasingly resistant to the pesticides used to control them. (C) A certain gene, if inherited by children from only one ot their parents, can render those children largely immune to infection with malaria. (D) Antimalaria vaccines, of which several are in development, are all designed to work by stimulating the body's immune system. (E) There are several distinct strains of malaria, and the body's immune response to any one of them does not protect it against the others.
