题目：

An overwhelming proportion of the most productive employees at SaleCo's regional offices work not eight hours a day, five days a week, as do other SaleCo employees, but rather ten hours a day, four days a week, with Friday off.  Noting this phenomenon, SaleCo's president plans to increase overall productivity by keeping the offices closed on Fridays and having all employees work the same schedule—ten hours a day, four days a week.
 
Which of the following, if true, provides the most reason to doubt that the president's plan, if implemented, will achieve its stated purpose?
 

选项:

A、Every employee of SaleCo who has been there for at least a year is entitled to three weeks of vacation each year and must be paid his or her regular salary for that time off.
B、None of the employees who work four days a week had volunteered to work that schedule, but all were assigned to it by their supervisors.
C、Working ten hours a day has allowed the most productive employees to work two hours alone each day in their respective offices relatively undisturbed by fellow employees.
D、Employees at SaleCo are compensated not on the basis of how many hours a week they work but on the basis of how productive they are during the hours they are at work.
E、Some of SaleCo's employees have indicated to company officials that they would quit if not allowed to work the same hours as the company's most productive employees.

    Behavior science courses should be gaining prominence in business school curricula. Recent theoretical work convincingly shows why behavioral factors such as organizational culture and employee relations are among the few remaining sources of sustainable competitive advantage in modern organizations. Furthermore, empirical evidence demonstrates clear linkages between human resource (HR) practices based in the behavioral sciences and various aspects of a firm's financial success. Additionally, some of the world's most successful organizations have made unique HR practices a core element of their overall business strategies.

    Yet the behavior sciences are struggling for credibility in many business schools. Surveys show that business students often regard behavioral studies as peripheral to the mainstream business curriculum. This perception can be explained by the fact that business students, hoping to increase their attractiveness to prospective employers, are highly sensitive to business norms and practices, and current business practices have generally been moving away from an emphasis on understanding human behavior and toward more mechanistic organizational models. Furthermore, the status of HR professionals within organizations tends to be lower than that of other executives. Students' perceptions would matter less if business schools were not increasingly dependent on external funding—form legislatures, businesses, and private foundations-for survival. Concerned with their institutions' ability to attract funding, administrators are increasingly targeting low-enrollment courses and degree programs for elimination.

题目：

The author of the passage suggests which of the following about HR professionals in business organizations?

选项:

A、They are generally skeptical about the value of mechanistic organizational models.
B、Their work increasingly relies on an understanding of human behavior.
C、Their work generally has little effect on the financial performance of those organizations.
D、Their status relative to other business executives affects the attitude of business school students toward the behavioral sciences.
E、Their practices are unaffected by the relative prominence of the behavioral sciences within business schools.

D

文章：

    Many economists believe that a high rate of business savings in the United States is a necessary precursor to investment, because business savings, as opposed to personal savings, comprise almost three-quarters of the national savings rate, and the national savings rate heavily influences the overall rate of business investment. These economists further postulate that real interest rates-the difference between the rates charged by lenders and the inflation rates-will be low when national savings exceed business investment (creating a savings surplus),and high when national savings fall below the level of business investment(creating a savings deficit ).

    However, during the 1960's real interest rates were often higher when the national savings surplus was large. Counter intuitive behavior also occurred when real interest rates skyrocketed from 2 percent in 1980 to 7 percent in 1982,even though national savings and investments were roughly equal throughout the period. Clearly, real interest rates respond to influences other than the savings/investment nexus. Indeed, real interest rates may themselves influence swings in the savings and investment rates. As real interest rates shot up after 1979, foreign investors poured capital into the United States, the price of domestic goods increased prohibitively abroad, and the price of foreign-made goods became lower in the United States. As a result, domestic economic activity and the ability of businesses to save and invest were restrained.

题目：

The author of the passage would be most likely to agree with which of the following statements regarding the economists mentioned in the highlighted text?

选项:

A、Their beliefs are contradicted by certain economic phenomena that occurred in the United States during the 1960's and the 1980's.
B、Their theory fails to predict under what circumstances the prices of foreign and domestic goods are likely to increase.
C、They incorrectly identify the factors other than savings and investment rates that affect real interest rates.
D、Their belief is valid only for the United States economy and not necessarily for other national economies.
E、They overestimate the impact of the real interest rate on the national savings and investment rates.

A

题目：

Goronian lawmaker:  Goronia's Cheese Importation Board, the agency responsible for inspecting all wholesale shipments of cheese entering Goronia from abroad and rejecting shipments that fail to meet specified standards, rejects about one percent of the cheese that it inspects.  Since the health consequences and associated costs of not rejecting that one percent would be negligible, whereas the cost of maintaining the agency is not, the agency's cost clearly outweighs the benefits it provides.
 
Knowing the answer to which of the following would be most useful in evaluating the lawmaker's argument?

选项:

A、Are any of the types of cheeses that are imported into Goronia also produced in Goronia?
B、Has the Cheese Importation Board, over the last several years, reduced its operating costs by eliminating inefficiencies within the agency itself?
C、Does the possibility of having merchandise rejected by the Cheese Importation Board deter many cheese exporters from shipping substandard cheese to Goronia?
D、Are there any exporters of cheese to Goronia whose merchandise is never rejected by the Cheese Importation Board?
E、How is the cheese rejected by the Cheese Importation Board disposed of?

文章：

Line         In 1955 Maurice Duverger published The Political
  Role of Women, the first behavioralist, multinational
  comparison of women’s electoral participation ever to
  use election data and survey data together.
(5) His study analyzed women’s patterns of voting,
  political candidacy, and political activism in four
  European countries during the first half of the
  twentieth century. Duverger’s research findings
  were that women voted somewhat less frequently
(10) than men (the difference narrowing the longer
  women had the vote) and were slightly more
  conservative.
       Duverger’s work set an early standard for the
  sensitive analysis of women’s electoral activities.
(15) Moreover, to Duverger’s credit, he placed his
  findings in the context of many of the historical
  processes that had shaped these activities.
  However, since these contexts have changed over
  time, Duverger’s approach has proved more durable
(20) than his actual findings. In addition, Duverger’s
  discussion of his findings was hampered by his failure
  to consider certain specific factors important to
  women’s electoral participation at the time he
  collected his data: the influence of political regimes,
(25) the effects of economic factors, and the
  ramifications of political and social relations between
  women and men. Given this failure, Duverger’s
  study foreshadowed the enduring limitations of the
  behavioralist approach to the multinational study of
(30) women’s political participation.


题目：

The author implies that Duverger’s actual findings are

选项:

A、limited because they focus on only four countries
B、inaccurate in their description of the four countries in the early 1950s
C、out-of-date in that they are inapplicable in the four countries today
D、flawed because they are based on unsound data
E、biased by Duverger’s political beliefs

文章：

Line         Jacob Burckhardt’s view that Renaissance
  European women “stood on a footing of perfect
  equality” with Renaissance men has been repeatedly
  cited by feminist scholars as a prelude to their
(5) presentation of rich historical evidence of women’s
  inequality. In striking contrast to Burckhardt, Joan
  Kelly in her famous 1977 essay, “Did Women Have
  a Renaissance?” argued that the Renaissance was
  a period of economic and social decline for women
(10) relative both to Renaissance men and to medieval
  women. Recently, however, a significant trend
  among feminist scholars has entailed a rejection
  of both Kelly’s dark vision of the Renaissance and
  Burckhardt’s rosy one. Many recent works by these
(15) scholars stress the ways in which differences
  among Renaissance women—especially in terms
  of social status and religion—work to complicate
  the kinds of generalizations both Burckhardt and
  Kelly made on the basis of their observations about
(20) upper-class Italian women.
       The trend is also evident, however, in works
  focusing on those middle- and upper-class
  European women whose ability to write gives them
  disproportionate representation in the historical
(25) record. Such women were, simply by virtue of
  their literacy, members of a tiny minority of the
  population, so it is risky to take their descriptions of
  their experiences as typical of “female experience”
  in any general sense. Tina Krontiris, for example, in
(30) her fascinating study of six Renaissance women
  writers, does tend at times to conflate “women” and
  “women writers,” assuming that women’s gender,
  irrespective of other social differences, including
  literacy, allows us to view women as a homogeneous
(35) social group and make that group an object of
  analysis. Nonetheless, Krontiris makes a significant
  contribution to the field and is representative of
  those authors who offer what might be called a
  cautiously optimistic assessment of Renaissance
(40) women’s achievements, although she also stresses
  the social obstacles Renaissance women faced
  when they sought to raise their “oppositional
  voices.” Krontiris is concerned to show women
  intentionally negotiating some power for themselves
(45) (at least in the realm of public discourse) against
  potentially constraining ideologies, but in her sober
  and thoughtful concluding remarks, she suggests
  that such verbal opposition to cultural stereotypes
  was highly circumscribed; women seldom attacked
(50) the basic assumptions in the ideologies that
  oppressed them.


题目：

The author of the passage discusses Krontiris primarily to provide an example of a writer who

选项:

A、is highly critical of the writings of certain Renaissance women
B、supports Kelly’s view of women’s status during the Renaissance
C、has misinterpreted the works of certain Renaissance women
D、has rejected the views of both Burckhardt and Kelly
E、has studied Renaissance women in a wide variety of social and religious contexts

D

题目：

With seventeen casinos, Moneyland operates the most casinos in a certain state. Although intent on expanding, it was outmaneuvered by Apex Casinos in negotiations to acquire the Eldorado chain. To complete its acquisition of Eldorado, Apex must sell five casinos to comply with a state law forbidding any owner to operate more than one casino per county. Since Apex will still be left operating twenty casinos in the state, it will then have the most casinos in the state.

Which of the following, if true, most seriously undermines the prediction?

选项:

A、Apex, Eldorado, and Moneyland are the only organizations licensed to operate casinos in the state.
B、The majority of Eldorado’s casinos in the state will need extensive renovations if they are to continue to operate profitably.
C、Some of the state’s counties do not permit casinos.
D、Moneyland already operates casinos in the majority of the state’s counties.
E、Apex will use funds it obtains from the sale of the five casinos to help fund its acquisition of the Eldorado chain.

A

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.
 
Which of the following, if discovered in experiments using artificially moved prey insects, would support one of the two hypotheses and undermine the other?
