Line         Historians remain divided over the role of
  banks in facilitating economic growth in the
  United States in the late eighteenth and early
  nineteenth centuries. Some scholars contend
(5) that banks played a minor role in the nation’s
  growing economy. Financial institutions, they
  argue, appeared only after the economy had
  begun to develop, and once organized, followed
  conservative lending practices, providing aid to
(10) established commercial enterprises but
  shunning those, such as manufacturing and
  transportation projects, that were more
  uncertain and capital-intensive (i.e., requiring
  greater expenditures in the form of capital than in
(15) labor).
       A growing number of historians argue, in
  contrast, that banks were crucial in transforming
  the early national economy. When state
  legislatures began granting more bank charters
(20) in the 1790s and early 1800s, the supply of
  credit rose accordingly. Unlike the earliest banks,
  which had primarily provided short-term loans to
  well-connected merchants, the banks of the early
  nineteenth century issued credit widely. As Paul
(25) Gilje asserts, the expansion and democratization
  of credit in the early nineteenth century became
  the driving force of the American economy, as
  banks began furnishing large amounts of capital
  to transportation and industrial enterprises. The
(30) exception, such historians argue, was in the
  South; here, the overwhelmingly agrarian nature
  of the economy generated outright opposition
  to banks, which were seen as monopolistic
  institutions controlled by an elite group of
(35) planters.

文章:

    In her account of unmarried women's experiences in colonial Philadelphia, Wulf argues that educated young women, particularly Quakers, engaged in resistance to patriarchal marriage by exchanging poetry critical of marriage, copying verse into their commonplace books. Wulf suggests that this critique circulated beyond the daughters of the Quaker elite and middle class, whose commonplace books she mines, proposing that Quaker schools brought it to many poor female students of diverse backgrounds.

    Here Wulf probably overstates Quaker schools' impact. At least three years' study would be necessary to achieve the literacy competence necessary to grapple with the material she analyzes. In 1765, the year Wulf uses to demonstrate the diversity of Philadelphia's Quaker schools, 128 students enrolled in these schools. Refining Wulf's numbers by the information she provides on religious affiliation, gender, and length of study, it appears that only about 17 poor non-Quaker girls were educated in Philadelphia's Quaker schools for three years or longer. While Wulf is correct that a critique of patriarchal marriage circulated broadly, Quaker schools probably cannot be credited with instilling these ideas in the lower classes. Popular literary satires on marriage had already landed on fertile ground in a multiethnic population that embodied a wide range of marital beliefs and practices. These ethnic and class-based traditions themselves challenged the legitimacy of patriarchal marriage.

题目:

Which of the following, if true, would most seriously undermine the author's basis for saying that Wulf overstates Quaker schools' impact (the highlighted text) ?

选项:

A、The information that Wulf herself provided on religious affiliation and gender of students is in fact accurate.
B、Most poor, non-Quaker students enrolled in Quaker schools had completed one or two years' formal or informal schooling before enrolling.
C、Not all of the young women whose commonplace books contained copies of poetry critical of marriage were Quakers.
D、The poetry featured in young women's commonplace books frequently included allusions that were unlikely to be accessible to someone with only three years' study in school.
E、In 1765 an unusually large proportion of the Quaker schools' student body consisted of poor girls from non-Quaker backgrounds.

    Findings from several studies on corporate mergers and acquisitions during the 1970's and 1980's raise questions about why firms initiate and consummate such transactions. One study showed, for example, that acquiring firms were on average unable to maintain acquired firms' pre-merger levels of profitability. A second study concluded that post-acquisition gains to most acquiring firms were not adequate to cover the premiums paid to obtain acquired firms. A third demonstrated that, following the announcement of a prospective merger, the stock of the prospective acquiring firm tends to increase in value much less than does that of the firm for which it bids. Yet mergers and acquisitions remain common, and bidders continue to assert that their objectives are economic ones. Acquisitions may well have the desirable effect of channeling a nation's resources efficiently from less to more efficient sectors of its economy, but the individual acquisitions executives arranging these deals must see them as advancing either their own or their companies' private economic interests. It seems that factors having little to do with corporate economic interests explain acquisitions. These factors may include the incentive compensation of executives, lack of monitoring by boards of directors, and managerial error in estimating the value of firms targeted for acquisition. Alternatively, the acquisition acts of bidders may derive from modeling: a manager does what other managers do.

题目:

The author of the passage implies that which of the following is a possible partial explanation for acquisition behavior during the 1970's and 1980's?

选项:

A、Managers wished to imitate other managers primarily because they saw how financially beneficial other firms' acquisitions were.
B、Managers miscalculated the value of firms that were to be acquired.
C、Lack of consensus within boards of directors resulted in their imposing conflicting goals on managers.
D、Total compensation packages for managers increased during that period.
E、The value of bidding firms' stock increased significantly when prospective mergers were announced.

文章:

    Many scholars have theorized that economic development, particularly industrialization and urbanization, contributes to the growth of participatory democracy; according to this theory, it would seem logical that women would both demand and gain suffrage in ever greater numbers whenever economic development expanded their economic opportunities. However, the economic development theory is inadequate to explain certain historical facts about the implementation of women's suffrage. For example, why was women's suffrage, instituted nationally in the United States in 1920, not instituted nationally in Switzerland until the 1970's? Industrialization was well advanced in both countries by 1920: over 33 percent of American workers were employed in various industries, as compared to 44 percent of Swiss workers. Granted, Switzerland and the United States diverged in the degree to which the expansion of industry coincided with the degree of urbanization: only 29 percent of the Swiss population lived in cities of 10,000 or more inhabitants by 1920. However, urbanization cannot fully explain women's suffrage. Within the United States prior to 1920, for example, only less urbanized states had granted women suffrage. Similarly, less urbanized countries such as Cambodia and Ghana had voting rights for women long before Switzerland did. It is true that Switzerland's urbanized cantons (political subdivisions) generally enacted women's suffrage legislation earlier than did rural cantons. However, these cantons often shared other characteristics—similar linguistic backgrounds and strong leftist parties—that may help to explain this phenomenon.

题目:

The passage states which of the following about Switzerland's urbanized cantons?

选项:

A、These cantons shared characteristics other than urbanization that may have contributed to their implementation of women's suffrage.
B、These cantons tended to be more politically divided than were rural cantons.
C、These cantons shared with certain rural cantons characteristics such as similar linguistic backgrounds and strong leftist parties.
D、The populations of these cantons shared similar views because urbanization furthered the diffusion of ideas among them.
E、These cantons were comparable to the most highly urbanized states in the United States in their stance toward the implementation of women's suffrage.

文章:

The Black Death, a severe epidemic that ravaged fourteenth-century Europe, has intrigued scholars ever since Francis Gasquet's 1893 study contending that this epidemic greatly intensified the political and religious upheaval that ended the Middle Ages.  Thirty-six years later, historian George Coulton agreed but, paradoxically, attributed a silver lining to the Black Death:  prosperity engendered by diminished competition for food, shelter, and work led survivors of the epidemic into the Renaissance and subsequent rise of modern Europe.
 
In the 1930s, however, Evgeny Kosminsky and other Marxist historians claimed the epidemic was merely an ancillary factor contributing to a general agrarian crisis stemming primarily from the inevitable decay of European feudalism.  In arguing that this decline of feudalism was economically determined, the Marxist asserted that the Black Death was a relatively insignificant factor.  This became the prevailing view until after the Second World War, when studies of specific regions and towns revealed astonishing mortality rates ascribed to the epidemic, thus restoring the central role of the Black Death in history.
 
This central role of the Black Death (traditionally attributed to bubonic plague brought from Asia) has been recently challenged from another direction.  Building on bacteriologist John Shrewsbury's speculations about mislabeled epidemics, zoologist Graham Twigg employs urban case studies suggesting that the rat population in Europe was both too sparse and insufficiently migratory to have spread plague.  Moreover, Twigg disputes the traditional trade-ship explanation for plague transmissions by extrapolating from data on the number of dead rats aboard Nile sailing vessels in 1912.  The Black Death, which he conjectures was anthrax instead of bubonic plague, therefore caused far less havoc and fewer deaths than historians typically claim.
 
Although correctly citing the exacting conditions needed to start or spread bubonic plague, Twigg ignores virtually a century of scholarship contradictory to his findings and employs faulty logic in his single-minded approach to the Black Death.  His speculative generalizations about the numbers of rats in medieval Europe are based on isolated studies unrepresentative of medieval conditions, while his unconvincing trade-ship argument overlooks land-based caravans, the overland migration of infected rodents, and the many other animals that carry plague.

题目:

Which of the following statements is most compatible with Kosminsky's approach to history, as it is presented in the passage?

选项:

A、The Middle Ages were ended primarily by the religious and political upheaval in fourteenth-century Europe.
B、The economic consequences of the Black Death included increased competition for food, shelter, and work.
C、European history cannot be studied in isolation from that of the rest of the world.
D、The number of deaths in fourteenth-century Europe has been greatly exaggerated by other historians.
E、The significance of the Black Death is best explained within the context of evolving economic systems.

Line        Conodonts, the spiky phosphatic remains (bones
 and teeth composed of calcium phosphate) of
 tiny marine animals that probably appeared about
 520 million years ago, were once among the most
(5)controversial of fossils. Both the nature of the
 organism to which the remains belonged and the
 function of the remains were unknown. However,
 since the 1981 discovery of fossils preserving not
 just the phosphatic elements but also other remains
(10)of the tiny soft-bodied animals (also called conodonts)
 that bore them, scientists' reconstructions of the
 animals' anatomy have had important implications
 for hypotheses concerning the development of the
 vertebrate skeleton.
(15)     The vertebrate skeleton had traditionally been
 regarded as a defensive development, champions of
 this view postulating that it was only with the much
 later evolution of jaws that vertebrates became
 predators. The first vertebrates, which were soft-
(20)bodied, would have been easy prey for numerous
 invertebrate carnivores, especially if these early
 vertebrates were sedentary suspension feeders.
 Thus, traditionalists argued, these animals developed
 coverings of bony scales or plates, and teeth were
(25)secondary features, adapted from the protective
 bony scales. Indeed, external skeletons of this
 type are common among the well-known fossils of
 ostracoderms, jawless vertebrates that existed from
 approximately 500 to 400 million years ago.
(30)However, other paleontologists argued that many of
 the definitive characteristics of vertebrates, such as
 paired eyes and muscular and skeletal adaptations
 for active life, would not have evolved unless the
(35)first vertebrates were predatory. Teeth were more
 primitive than external armor according to this view,
 and the earliest vertebrates were predators.
      The stiffening notochord along the back of the
 body, V-shaped muscle blocks along the sides,
(40)and posterior tail fins help to identify conodonts as
 among the most primitive of vertebrates. The lack of
 any mineralized structures apart from the elements
 in the mouth indicates that conodonts were more
 primitive than the armored jawless fishes such as the
(45)ostracoderms. It now appears that the hard parts that
 first evolved in the mouth of an animal improved its
 efficiency as a predator, and that aggression rather
 than protection was the driving force behind the origin
 of the vertebrate skeleton.

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.
