题目:

During the past year, Pro-Tect Insurance Company's total payout on car-theft claims has been larger than the company can afford to sustain.  Pro-Tect cannot reduce the number of car-theft policies it carries, so it cannot protect itself against continued large payouts that way.  Therefore, Pro-Tect has decided to offer a discount to holders of car-theft policies whose cars have antitheft devices.  Many policyholders will respond to the discount by installing such devices, since the amount of the discount will within two years typically more than cover the cost of installation.  Thus, because cars with antitheft devices are rarely stolen, Pro-Tect's plan is likely to reduce its annual payouts.
In the argument above, the two portions in boldface play which of the following roles?

选项:

A、The first and the second are both evidence offered by the argument as support for its main conclusion.
B、The first presents a problem a response to which the argument assesses; the second is the judgment reached by that assessment.
C、The first is the position the argument seeks to establish; the second is a judgment the argument uses to support that position.
D、The first is a development that the argument seeks to explain; the second is a prediction the argument makes in support of the explanation it offers.
E、The first presents a development whose likely outcome is at issue in the argument; the second is a judgment the argument uses in support of its conclusion about that outcome.

文章:

    Some historians contend that conditions in the United States during the Second World War gave rise to a dynamic wartime alliance between trade unions and the African American community, an alliance that advanced the cause of civil rights. They conclude that the postwar demise of this vital alliance constituted a lost opportunity for the civil rights movement that followed the war. Other scholars, however, have portrayed organized labor as defending all along the relatively privileged position of White workers relative to African American workers. Clearly, these two perspectives are not easily reconcilable, but the historical reality is not reducible to one or the other. Unions faced a choice between either maintaining the prewar status quo or promoting a more inclusive approach that sought for all members the right to participate in the internal affairs of unions, access to skilled and high-paying positions within the occupational hierarchy, and protection against management's arbitrary authority in the workplace. While union representatives often voiced this inclusive ideal, in practice unions far more often favored entrenched interests. The accelerating development of the civil rights movement following the Second World War exacerbated the unions' dilemma, forcing trade unionists to confront contradictions in their own practices.

题目:

Which of the following best describes the purpose of in the highlighted text in the second paragraph in the passage?

选项:

A、To summarize a situation confronted by unions during the Second World War
B、To summarize the role of unions in the workplace during the Second World War

D、To assess the effect of the growth of the civil rights movement on unions during the Second World War
E、To present a criticism of the unions' approach to representing workers during the Second World War

文章:

Colonial historian David Allen's intensive study of five communities in seventeenth-century Massachusetts is a model of meticulous scholarship on the detailed microcosmic level, and is convincing up to a point.  Allen suggests that much more coherence and direct continuity existed between English and colonial agricultural practices and administrative organization than other historians have suggested.  However, he overstates his case with the declaration that he has proved "the remarkable extent to which diversity in New England local institutions was directly imitative of regional differences in the mother country."
 
Such an assertion ignores critical differences between seventeenth-century England and New England.  First, England was overcrowded and land-hungry; New England was sparsely populated and labor-hungry.  Second, England suffered the normal European rate of mortality; New England, especially in the first generation of English colonists, was virtually free from infectious diseases.  Third, England had an all-embracing state church; in New England membership in a church was restricted to the elect.  Fourth, a high proportion of English villagers lived under paternalistic resident squires; no such class existed in New England.  By narrowing his focus to village institutions and ignoring these critical differences, which studies by Greven, Demos, and Lockridge have shown to be so important, Allen has created a somewhat distorted picture of reality.
 
Allen's work is a rather extreme example of the "country community" school of seventeenth-century English history whose intemperate excesses in removing all national issues from the history of that period have been exposed by Professor Clive Holmes.  What conclusion can be drawn, for example, from Allen's discovery that Puritan clergy who had come to the colonies from East Anglia were one-third to one-half as likely to return to England by 1660 as were Puritan ministers from western and northern England?  We are not told in what way, if at all, this discovery illuminates historical understanding.  Studies of local history have enormously expanded our horizons, but it is a mistake for their authors to conclude that village institutions are all that mattered, simply because their functions are all that the records of village institutions reveal.

题目:

The passage suggests that Professor Clive Holmes would most likely agree with which of the following statements?

选项:

A、An understanding of seventeenth-century English local institutions requires a consideration of national issues.
B、The 'country community' school of seventeenth-century English history distorts historical evidence in order to establish continuity between old and new institutions.
C、Most historians distort reality by focusing on national concerns to the exclusion of local concerns.
D、National issues are best understood from the perspective of those at the local level.
E、Local histories of seventeenth-century English villages have contributed little to the understanding of village life.

题目:

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?

选项:

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.

文章:

Jon Clark’s study of the effect of the modernization of a telephone exchange on exchange maintenance work and workers is a solid contribution to a debate that encompasses two lively issues in the history and sociology of technology: technological determinism and social constructivism.

Clark makes the point that the characteristics of a technology have a decisive influence on job skills and work organization. Put more strongly, technology can be a primary determinant of social and managerial organization. Clark believes this possibility has been obscured by the recent sociological fashion, exemplified by Braverman’s analysis, that emphasizes the way machinery reflects social choices. For Braverman, the shape of a technological system is subordinate to the manager’s desire to wrest control of the labor process from the workers. Technological change is construed as the outcome of negotiations among interested parties who seek to incorporate their own interests into the design and configuration of the machinery. This position represents the new mainstream called social constructivism.

The constructivists gain acceptance by misrepresenting technological determinism: technological determinists are supposed to believe, for example, that machinery imposes appropriate forms of order on society. The alternative to constructivism, in other words, is to view technology as existing outside society, capable of directly influencing skills and work organization.

Clark refutes the extremes of the constructivists by both theoretical and empirical arguments. Theoretically he defines "technology" in terms of relationships between social and technical variables. Attempts to reduce the meaning of technology to cold, hard metal are bound to fail, for machinery is just scrap unless it is organized functionally and supported by appropriate systems of operation and maintenance. At the empirical level Clark shows how a change at the telephone exchange from maintenance-intensive electromechanical switches to semi-electronic switching systems altered work tasks, skills, training opportunities, administration, and organization of workers. Some changes Clark attributes to the particular way management and labor unions negotiated the introduction of the technology, whereas others are seen as arising from the capabilities and nature of the technology itself. Thus Clark helps answer the question: "When is social choice decisive and when are the concrete characteristics of technology more important?"

题目:

Which of the following statements about the modernization of the telephone exchange is supported by information in the passage?

选项:

A、The new technology reduced the role of managers in labor negotiations.The modernization was implemented without the consent of the employees directly affected by it.
B、The modernization had an impact that went significantly beyond maintenance routines.
C、Some of the maintenance workers felt victimized by the new technology.
D、The modernization gave credence to the view of advocates of social constructivism.

题目:

According to the Tristate Transportation Authority, making certain improvements to the main commuter rail line would increase ridership dramatically. The authority plans to finance these improvements over the course of five years by raising automobile tolls on the two highway bridges along the route the rail line serves. Although the proposed improvements are indeed needed, the authority's plan for securing the necessary funds should be rejected because it would unfairly force drivers to absorb the entire cost of something from which they receive no benefit.
Which of the following, if true, would cast the most doubt on the effectiveness of the authority's plan to finance the proposed improvements by increasing bridge tolls?

选项:

A、Before the authority increases tolls on any of the area bridges, it is required by law to hold public hearings at which objections to the proposed increase can be raised.
B、Whenever bridge tolls are increased, the authority must pay a private contractor to adjust the automated toll-collecting machines. 
C、Between the time a proposed toll increase is announced and the time the increase is actually put into effect, many commuters buy more tokens than usual to postpone the effects of the increase. 
D、When tolls were last increased on the two bridges in question, almost 20 percent of the regular commuter traffic switched to a slightly longer alternative route that has since been improved.
E、The chairman of the authority is a member of the Tristate Automobile dub that has registered strong opposition to the proposed toll increase.

Sports Association

Statement by sports association spokes-­person:

Our sports association issues contracts to television networks for the exclusive right to broadcast our sporting events. For this right, the networks pay the association substantial fees, which help finance our leagues. We also provide free media passes to our events for journalists so that they can effectively report on sports news, including final scores. Now, how­ever, some news organizations are posting video clips, audio clips, digital photographs, and live score updates from our events on their websites. Conditions must be placed on these practices, which go beyond mere sports news reporting; they harm the value of our broad­casting contracts and violate our rights as the owners of the sports leagues. News organiza­tions that wish to post such information on their websites should therefore sign contracts with the sports association that stipulate what post­ings will be allowed and how much they will cost. As we have in the past, we will deny media passes to journalists from news organi­zations that do not comply with our require­ments.

News Organizations

Statement by news organizations spokes­person:

me news business has largely shifted (rom print media to the Internet, where readers expect text to be accompanied by audio and Images To charge news organizations for providing online sports coverage or to place unnecessary conditions on that coverage is to deny news organizations their right to cover the news. Online news sites are not asking to broadcast sporting events In their entirety, and their sports reporting does not detract from the value of the sports leagues or their events. On the contrary—free, engaging sports reporting generates interest in sports and thus benefits readers and the sports association alike. News organizations must be allowed to report freely about sports on their websites, in any time­frame, using any type of online medium they deem effective.

Art historian: Unlike many artistic traditions that sought to depict plants native to the local area in a seasonally appropriate way (for example, depicting scenes of spring with the plants in the appropriate stages of development for that season), seventeenth-century Dutch artists specializing in flower paintings almost exclusively chose to depict exotic species of flowers from outside the local area. Painting such species was worthwhile primarily because the art-buying public had developed a strong preference for images of the exotic. The great botanical centers of the time gave the artists direct access to such flowers, which the artists would freely combine in a single painting, regardless of whether the combined species occurred together in the wild, and depicted each in full bloom, regardless of whether those species bloomed at the same time in nature.

Statement: The art historian makes the point that the species of flowers these Dutch artists chose to paint were 1 largely because the species were 2 .

Select for 1 and for 2 the options that complete the statement so that it is most strongly supported by the information provided. Make only two selections, one in each column.

Tiger beetles are such fast runners that they can capture virtually any nonflying insect.  However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack.  Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.
