Line         Two works published in 1984 demonstrate
  contrasting approaches to writing the history of
  United States women. Buel and Buel’s biography
  of Mary Fish (1736–1818) makes little effort to
(5) place her story in the context of recent
  historiography on women. Lebsock, meanwhile,
  attempts not only to write the history of women in
  one southern community, but also to redirect two
  decades of historiographical debate as to
(10) whether women gained or lost status in the
  nineteenth century as compared with the
  eighteenth century. Although both books offer the
  reader the opportunity to assess this controversy
  regarding women’s status, only Lebsock’s deals with
(15) it directly. She examines several different aspects
  of women’s status, helping to refine and resolve the
  issues. She concludes that while
  women gained autonomy in some areas,
  especially in the private sphere, they lost it in
(20) many aspects of the economic sphere. More
  importantly, she shows that the debate itself
  depends on frame of reference: in many respects,
  women lost power in relation to men, for example,
  as certain jobs (delivering babies, supervising
(25) schools) were taken over by men. Yet women also
  gained power in comparison with their previous
  status, owning a higher proportion of real estate,
  for example. In contrast, Buel and Buel’s
  biography provides ample raw material for
(30) questioning the myth, fostered by some
  historians, of a colonial golden age in the
  eighteenth century but does not give the reader
  much guidance in analyzing the controversy over
  women’s status.


题目：

With which of the following characterizations of Lebsock’s contribution to the controversy concerning women’s status in the nineteenth-century United States would the author of the passage be most likely to agree?

选项:

A、Lebsock has studied women from a formerly neglected region and time period.
B、Lebsock has demonstrated the importance of frame of reference in answering questions about women’s status.
C、Lebsock has addressed the controversy by using women’s current status as a frame of reference.
D、Lebsock has analyzed statistics about occupations and property that were previously ignored.
E、Lebsock has applied recent historiographical methods to the biography of a nineteenth-century woman.

文章：

The modern multinational corporation is described as having originated when the owner-managers of nineteenth-century British firms carrying on international trade were replaced by teams of salaried managers organized into hierarchies.  Increases in the volume of transactions in such firms are commonly believed to have necessitated this structural change.  Nineteenth-century inventions like the steamship and the telegraph, by facilitating coordination of managerial activities, are described as key factors. Sixteenth- and seventeenth-century chartered trading companies, despite the international scope of their activities, are usually considered irrelevant to this discussion:  the volume of their transactions is assumed to have been too low and the communications and transport of their day too primitive to make comparisons with modern multinationals interesting.
 
In reality, however, early trading companies successfully purchased and outfitted ships, built and operated offices and warehouses, manufactured trade goods for use abroad, maintained trading posts and production facilities overseas, procured goods for import, and sold those goods both at home and in other countries.  The large volume of transactions associated with these activities seems to have necessitated hierarchical management structures well before the advent of modern communications and transportation.  For example, in the Hudson's Bay Company, each far-flung trading outpost was managed by a salaried agent, who carried out the trade with the Native Americans, managed day-to-day operations, and oversaw the post's workers and servants.  One chief agent, answerable to the Court of Directors in London through the correspondence committee, was appointed with control over all of the agents on the bay.
 
The early trading companies did differ strikingly from modern multinationals in many respects.  They depended heavily on the national governments of their home countries and thus characteristically acted abroad to promote national interests.  Their top managers were typically owners with a substantial minority share, whereas senior managers' holdings in modern multinationals are usually insignificant.  They operated in a preindustrial world, grafting a system of capitalist international trade onto a premodern system of artisan and peasant production.  Despite these differences, however, early trading companies organized effectively in remarkably modern ways and merit further study as analogues of more modern structures.

题目：

According to the passage, early chartered trading companies are usually described as

选项:

A、irrelevant to a discussion of the origins of the modern multinational corporation
B、interesting but ultimately too unusual to be good subjects for economic study
C、analogues of nineteenth-century British trading firms
D、rudimentary and very early forms of the modern multinational corporation
E、important national institutions because they existed to further the political aims of the governments of their home countries

A

题目：

Candle Corporation’s television stations are likely to have more income from advertisers than previously. This is because advertisers prefer to reach people in the 18- to 49-year-old age group and the number of people in that group watching Candle television is increasing. Furthermore, among Candle viewers, the percentage of viewers 18 to 49 years old is increasing.

Which of the following, if true, would most strengthen the argument that Candle Corporation will receive more income from advertisers?

选项:

A、Advertisers carefully monitor the demographic characteristics of television audiences and purchase advertising time to reach the audiences they prefer to reach.
B、Among people over 49 years old, fewer viewers of Candle stations buy products advertised on television than do viewers of other stations.
C、There will be increasingly more advertisements on television that are directed at viewers who are over 49 years old.
D、Candle stations plan to show reruns of television shows during hours when other stations run shows for the first time.
E、People 18 to 49 years old generally have less disposable income to spend than do people over 49 years old.

A

题目：

In a study conducted in Canada, servers in various restaurants wrote "Thank you" on randomly selected bills before presenting the bills to their customers. Tips on these bills were an average of three percentage points higher than bps on bills without the message. Therefore, if servers in Canada regularly wrote "Thank you" on restaurant bills, their average income from tips would be significantly higher than it otherwise would have been.
Which of the following is an assumption on which the argument relies?

选项:

A、The "Thank you" messages would have the same impact on regular patrons of a restaurant as they would on occasional patrons of the same restaurant. 
B、Regularly seeing "Thank you" written on their bills would not lead restaurant patrons to revert to their earlier tipping habits. 
C、The written "Thank you" reminds restaurant patrons that tips constitute a significant part of the income of many food servers. 
D、The rate at which people tip food servers in Canada does not vary with how expensive a restaurant is. 
E、Virtually al patrons of the Canadian restaurants in the study who were given a bill with "Thank you" written on it left a larger tip than they otherwise would have.

题目：

Since 1990 the percentage of bacterial sinus infections in Aqadestan that are resistant to the antibiotic perxicillin has increased substantially. Bacteria can quickly develop resistance to an antibiotic when it is prescribed indiscriminately or when patients fail to take it as prescribed. Since perxicillin has not been indiscriminately prescribed, health officials hypothesize that the increase in perxicillin-resistant sinus infections is largely due to patients' failure to take this medication as prescribed.

Which of the following, if true of Aqadestan, provides most support for the health officials' hypothesis?

题目：

Correctly measuring the productivity of service workers is complex. Consider, for example, postal workers: they are often said to be more productive if more letters are delivered per postal worker. But is this really true? What if more letters are lost or delayed per worker at the same times that more are delivered?
The objection implied above to the productivity measure described is based on doubts about the truth of which of the following statements?

选项:

A、Postal workers are representative of service workers in general. 
B、The delivery of letters is the primary activity of the postal service. 
C、Productivity should be ascribed to categories of workers, not to individuals.
D、The quality of services rendered can appropriately be ignored in computing productivity. 
E、The number of letters delivered is relevant to measuring the productivity of postal workers.

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.
