Line         In an effort to explain why business acquisitions
  often fail, scholars have begun to focus on the role
  of top executives of acquired companies. Acquired
  companies that retain their top executives tend to
(5) have more successful outcomes than those that do
  not. Furthermore, existing research suggests that
  retaining the highest-level top executives, such as the
  CEO (chief executive officer) and COO (chief operating
  officer), is related more positively to postacquisition
(10) success than retaining lower-ranked top executives.
  However, this explanation, while insightful, suffers from
  two limitations. First, the focus on positional rank does
  not recognize the variation in length of service that
  may exist in top executive posts across companies,
(15) nor does it address which particular top executives
  (with respect to length of service) should be retained
  to achieve a successful acquisition outcome. Second,
  the relationship between retained top executives and
  acquisition outcomes offered by existing research
(20) is subject to opposing theoretical explanations
  related to length of service. The resource-based view
  (RBV) suggests that keeping acquired company top
  executives with longer organizational tenure would lead
  to more successful outcomes, as those executives
(25) have idiosyncratic and nontransferable knowledge
  of the acquired company that would be valuable for
  the effective implementation of the acquisition. The
  opposing position, offered by the upper echelons
  perspective (UEP), suggests that retaining top
(30) executives having short organizational tenure would
  lead to more successful outcomes, as they would have
  the adaptability to manage most effectively during the
  uncertainty of the acquisition process.
       Responding to these limitations, Bergh conducted
(35) a study of executive retention and acquisition
  outcome that focused on the organizational tenure of
  retained company top executives in 104 acquisitions,
  followed over 5 years. Bergh considered the
  acquisition successful if the acquired company was
(40) retained and unsuccessful if it was divested. Bergh’s
  findings support the RBV position. Apparently, the
  benefits of long organizational tenure lead to more
  successful outcomes than the benefits of short
  organizational tenure. While longer tenured top
(45) executives may have trouble adapting to change, it
  appears that their perspectives and knowledge bases
  offer unique value after the acquisition. Although
  from the UEP position it seems sensible to retain
  less tenured executives and allow more tenured
(50) ones to leave, such a strategy appears to lower the
  probability of acquisition success.


题目：

According to the passage, prior to Bergh’s study, research on the role of top executives of acquired companies in business acquisition success was limited in which of the following ways?

选项:

A、It did not address how the organizational tenure of top executives affects postacquisition success.
B、It did not address why some companies have longer-tenured CEOs than others.
C、It did not consider strategies for retaining long-tenured top executives of acquired companies.
D、It failed to differentiate between the contribution of highest-level top executives to postacquisition success and that of lower-ranked top executives.
E、It underestimated the potential contribution that lower-level top executives can make to postacquisition success.

A

文章：

Last year all refuse collected by Shelbyville city services was incinerated. This incineration generated a large quantity of residual ash. In order to reduce the amount of residual ash Shelbyville generates this year to half of last year’s total, the city has revamped its collection program. This year city services will separate for recycling enough refuse to reduce the number of truckloads of refuse to be incinerated to half of last year’s number.

题目：

Which of the following is required for the revamped collection program to achieve its aim?

选项:

A、This year, no materials that city services could separate for recycling will be incinerated. Separating recyclable materials from materials to be incinerated will cost Shelbyville less than half what it cost last year to dispose of the residual ash. 
B、Refuse collected by city services will contain a larger proportion of recyclable materials this year than it did last year. 
C、The refuse incinerated this year will generate no more residual ash per truckload incinerated than did the refuse incinerated last year. 
D、The total quantity of refuse collected by Shelbyville city services this year will be no greater than that collected last year.

D

题目：

The claims above, if true, most strongly support which of the following conclusions?

选项:

A、The balance of opinion is likely to favor Patria in the event of a blockade. As long as international opinion is unanimously against Patria, a trade embargo is likely to succeed
B、A naval blockade of Patria's ports would ensure that no goods enter or leave Patria. 
C、Any trade embargo against Patria would be likely to fail at some time.

题目：

The kinds of hand and wrist injuries that result from extended use of a computer while maintaining an incorrect posture are common among schoolchildren in Harnville. Computers are important to the school curriculum there, so instead of reducing the amount their students use computers, teachers plan to bring about a sharp reduction in the number of these injuries by carefully monitoring their students' posture when using computers in the classroom.

Which of the following would it be most useful to know in order to assess the likelihood that the teachers' plan will be successful?

选项:

A、Whether extended use of a computer while maintaining incorrect posture can cause injuries other than hand and wrist injuries
B、Whether hand and wrist injuries not caused by computer use are common among schoolchildren in Harnville
C、What proportion of schoolchildren in Harnville with hand and wrist injuries use computers extensively outside the classroom
D、Whether changes in the curriculum could reduce the schools' dependence on computers
E、What proportion of schoolchildren in Harnville already use correct posture while using a computer

题目：

The heavy traffic in Masana is a growing drain on the city's economy—the clogging of the streets of the central business district alone cost the economy more than $1.2 billion over the past year. In order to address this problem, officials plan to introduce congestion pricing, by which drivers would pay to enter the city's most heavily trafficked areas during the busiest times of the day.

Which of the following, if true, would most strongly indicate that the plan will be a success?

选项:

A、Approximately one-fifth of the vehicles in the central business district are in transit from one side of the city to the other.
B、Planners expect that, without congestion pricing, traffic in Masana is likely to grow by 6 percent in the next five years.
C、In other urban areas, congestion pricing has strongly encouraged carpooling (sharing of rides by private commuters).
D、Several studies have shown that a reduction in traffic of 15 percent in Masana could result in 5,500 or more new jobs.
E、Over 30 percent of the vehicles in the city's center are occupied by more than one person.

文章：

    Extensive research has shown that the effects of short-term price promotions on sales are themselves short-term. Companies' hopes that promotions might have a positive aftereffect have not been borne out for reasons that researchers have been able to identify. A price promotion entices only a brand's long-term or "loyal" customers; people seldom buy an unfamiliar brand merely because the price is reduced. They simply avoid paying more than they have to when one of their customary brands is temporarily available at a reduced price. A price promotion does not increase the number of long-term customers of a brand, as it attracts virtually no new customers in the first place. Nor do price promotions have lingering aftereffects for a brand, even negative ones such as damage to a brand's reputation or erosion of customer loyalty, as is often feared.

    So why do companies spend so much on price promotions? Clearly price promotions are generally run at a loss, otherwise there would be more of them. And the bigger the increase in sales at promotion prices, the bigger the loss. While short-term price promotions can have legitimate uses, such as reducing excess inventory, it is the recognizable increase in sales that is their main attraction to management, which is therefore reluctant to abandon this strategy despite its effect on the bottom line.

题目：

It can be inferred from the passage that if a company ceased to run short-term price promotions for a particular product, an effect of this change would be to

选项:

A、reduce excess inventory of the product
B、lose some of the product's long-term customers
C、reduce the product's overall sales
D、inhibit growth in the number of the product's customers
E、threaten the product's profitability

C

文章：

Conventional wisdom has it that large deficits in the United States budget cause interest rates to rise.  Two main arguments are given for this claim.  According to the first, as the deficit increases, the government will borrow more to make up for the ensuing shortage of funds.  Consequently, it is argued, if both the total supply of credit (money available for borrowing) and the amount of credit sought by nongovernment borrowers remain relatively stable, as is often supposed, then the price of credit (the interest rate) will increase.  That this is so is suggested by the basic economic principle that if supplies of a commodity (here, credit) remain fixed and demand for that commodity increases, its price will also increase.  The second argument supposes that the government will tend to finance its deficits by increasing the money supply with insufficient regard for whether there is enough room for economic growth to enable such an increase to occur without causing inflation.  It is then argued that financiers will expect the deficit to cause inflation and will raise interest rates, anticipating that because of inflation the money they lend will be worth less when paid back.
 
Unfortunately for the first argument, it is unreasonable to assume that nongovernment borrowing and the supply of credit will remain relatively stable.  Nongovernment borrowing sometimes decreases.  When it does, increased government borrowing will not necessarily push up the total demand for credit.  Alternatively, when credit availability increases, for example through greater foreign lending to the United States, then interest rates need not rise, even if both private and government borrowing increase.
 
The second argument is also problematic.  Financing the deficit by increasing the money supply should cause inflation only when there is not enough room for economic growth.  Currently, there is no reason to expect deficits to cause inflation.  However, since many financiers believe that deficits ordinarily create inflation, then admittedly they will be inclined to raise interest rates to offset mistakenly anticipated inflation.  This effect, however, is due to ignorance, not to the deficit itself, and could be lessened by educating financiers on this issue.

题目：

The author uses the term "admittedly" (see highlighted text) in order to indicate that

选项:

A、the second argument has some truth to it, though not for the reasons usually supposed
B、the author has not been successful in attempting to point out inadequacies in the two arguments
C、the thesis that large deficits directly cause interest rates to rise has strong support after all
D、financiers should admit that they were wrong in thinking that large deficits will cause higher inflation rates
E、financiers generally do not think that the author's criticisms of the second argument are worthy of consideration

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?
