文章:

    Many managers are influenced by dangerous myths about pay that lead to counterproductive decisions about how their companies compensate employees. One such myth is that labor rates, the rate per hour paid to workers, are identical with labor costs, the money spent on labor in relation to the productivity of the labor force. This myth leads to the assumption that a company can simply lower its labor costs by cutting wages. But labor costs and labor rates are not in fact the same: one company could pay its workers considerably more than another and yet have lower labor costs if that company's productivity were higher due to the talent of its workforce, the efficiency of its work processes, or other factors. The confusion of costs with rates persists partly because labor rates are a convenient target for managers who want to make an impact on their company's budgets. Because labor rates are highly visible, managers can easily compare their company's rates with those of competitors. Furthermore, labor rates often appear to be a company's most malleable financial variable: cutting wages appears an easier way to control costs than such options as reconfiguring work processes or altering product design.

    The myth that labor rates and labor costs are equivalent is supported by business journalists, who frequently confound the two. For example, prominent business journals often remark on the "high" cost of German labor, citing as evidence the average amount paid to German workers. The myth is also perpetuated by the compensation consulting industry, which has its own incentives to keep such myths alive. First, although some of these consulting firms have recently broadened their practices beyond the area of compensation, their mainstay continues to be advising companies on changing their compensation practices. Suggesting that a company's performance can be improved in some other way than by altering its pay system may be empirically correct but contrary to the consultants' interests. Furthermore, changes to the compensation system may appear to be simpler to implement than changes to other aspects of an organization, so managers are more likely to find such advice from consultants palatable. Finally, to the extant that changes in compensation create new problems, the consultants will continue to have work solving the problems that result from their advice.

题目:

It can be inferred from the passage that the author would be most likely to agree with which of the following statements about compensation?

选项:

A、A company's labor costs are not affected by the efficiency of its work processes.
B、High labor rates are not necessarily inconsistent with the goals of companies that want to reduce costs
C、It is more difficult for managers to compare their companies' labor rates with those of competitors than to compare labor costs.
D、A company whose labor rates are high is unlikely to have lower labor costs than other companies.
E、Managers often use information about competitors' labor costs to calculate those companies' labor rates.

题目:

The milk of many mammals contains cannabinoids, substances that are known to stimulate certain receptors in the brain. To investigate the function of cannabinoids, researchers injected newborn mice with a chemical that is known to block cannabinoides from reaching their receptors in the brain. The injected mice showed far less interest in feeding than normal newborn mice do. Therefore, cannabinoids probably function to stimulate the appetite.
 
Which of the following is an assumption on which the argument depends?

选项:

A、Newborn mice do not normally ingest any substance other than their mothers' milk.
B、Cannabinoids are the only substances in mammals' milk that stimulate the appetite.
C、The mothers of newborn mice do not normally make any effort to encourage their babies to feed.
D、The milk of mammals would be less nutritious if it did not contain cannabinoids.
E、The chemical that blocks cannabinoids from stimulating their brain receptors does not independently inhibit the appetite.

E

题目:

Ecologist:  The Scottish Highlands were once the site of extensive forests, but these forests have mostly disappeared and been replaced by peat bogs.  The common view is that the Highlands' deforestation was caused by human activity, especially agriculture. However, agriculture began in the Highlands less than 2,000 years ago.  Peat bogs, which consist of compressed decayed vegetable matter, build up by only about one foot per 1,000 years and, throughout the Highlands, remains of trees in peat bogs are almost all at depths great than four feet.  Since climate changes that occurred between 7,000 and 4,000 years ago favored the development of peat bogs rather than the survival of forests, the deforestation was more likely the result of natural processes than of human activity.
 
In the ecologist's argument the two portions in boldface play which of the following roles?

选项:

A、The first is evidence that has been used in support of a position that the ecologist rejects; the second is a finding that the ecologist uses to counter that evidence.
B、The first is evidence that, in light of the evidence provided in the second, serves as grounds for the ecologist's rejection of a certain position.
C、The first is a position that the ecologist rejects; the second is evidence that has been used in support of that position.
D、The first is a position that the ecologist rejects; the second provides evidence in support of that rejection.
E、The first is a position for which the ecologist argues; the second provides evidence to support that position.

题目:

Scientists typically do their most creative work before the age of forty.  It is commonly thought that this happens because aging by itself brings about a loss of creative capacity.  However, studies show that a disproportionately large number of the scientists who produce highly creative work beyond the age of forty entered their field at an older age than is usual.  Since by the age of forty the large majority of scientists have been working in their field for at least fifteen years, the studies' finding strongly suggests that the real reason why scientists over forty rarely produce highly creative work is not that they have simply aged but rather that they generally have spent too long in a given field.
 
In the argument given, the two portions in boldface play which of the following roles?

选项:

A、The first is the position that the argument as a whole opposes; the second is an objection that has been raised against a position defended in the argument.
B、The first is a claim that has been advanced in support of a position that the argument opposes; the second is a finding that has been used in support of that position.
C、The first is an explanation that the argument challenges; the second is a finding that has been used in support of that explanation.
D、The first is an explanation that the argument challenges; the second is a finding on which that challenge is based.
E、The first is an explanation that the argument defends; the second is a finding that has been used to challenge that explanation.

题目:

Often patients with ankle fractures that are stable, and thus do not require surgery, are given follow-up x-rays because their orthopedists are concerned about possibly having misjudged the stability of the frac- ture. When a number of follow-up x-rays were reviewed, however, all
the fractures that had initially been judged stable were found to have healed correctly. Therefore, it is a waste of money to order follow-up
x-rays of ankle fracture initially judged stable.
 
Which of the following, if true, most strengthens the argument?

选项:

A、Doctors who are general practitioners rather than orthopedists are less likely than orthopedists to judge the stability of an ankle frac-ture correctly.
B、Many ankle injuries for which an initial x-ray is ordered are revealed by the x-ray not to involve any fracture of the ankle.
C、X-rays of patients of many different orthopedists working in several hospitals were reviewed.
D、The healing of ankle fractures that have been surgically repaired is always checked by means of a follow-up x-ray.
E、Orthopedists routinely order follow-up x-rays for fractures of bone other than ankle bones.

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.
