题目：

One way to judge the performance of a company is to compare it with other companies. This technique, commonly called "benchmarking," permits the manager of a company to discover better industrial practices and can provide a justification for the adoption of good practices.

Any of the following, if true, is a valid reason for benchmarking the performance of a company against companies with which it is not in competition rather than against competitors EXCEPT:

选项:

A、Comparisons with competitors are most likely to focus on practices that the manager making the comparisons already employs.
B、Getting 'inside' information about the unique practices of competitors is particularly difficult.
C、Since companies that compete with each other are likely to have comparable levels of efficiency, only benchmarking against noncompetitors is likely to reveal practices that would aid in beating competitors.
D、Managers are generally more receptive to new ideas that they find outside their own industry.
E、Much of the success of good companies is due to their adoption of practices that take advantage of the special circumstances of their products or markets.

答案:

E

题目：

Driving the steep road to the mountaintop Inca ruins of Machu Picchu is potentially dangerous and hiking there is difficult.  Now the Peruvian government is installing a cable car that will make access much easier, and hence result in a large increase in tourism.  However, since the presence of large numbers of tourists tends to accelerate the deterioration of a site, installation of the cable car is certain to result in harm to the ruins.
 
Which of the following, if true, most seriously calls into question the argument?

选项:

A、The daily number of tourists that are expected to take the cable car to Machu Piccu is smaller than the original resident population of Incas.
B、The construction of the cable car terminal at Machu Picchu will require the use of potentially damaging heavy machinery at the site.
C、Machu Picchu is already one of the most popular tourist sites in Peru.
D、Natural weathering will continue to be a more significant cause of the deterioration of Machu Picchu than tourist traffic.
E、The cable car will replace the tour buses whose large wheels and corrosive exhaust at present do significant damage to the site.

E

题目：

In the two years following the unification of Germany in 1989, the number of cars owned by residents of East Germany and the total distance traveled by cars in East Germany both increased by about 40 percent.  In those two years, however, the number of East German residents killed each year as car occupants in traffic accidents increased by about 300 percent.
 
Which of the following, if true, most helps to explain the disproportionate increase in traffic fatalities?

选项:

A、The average number of passengers per car was higher in the years before unification than it was in the two years after.
B、After unification, many people who had been living in East Germany relocated to West Germany.
C、After unification, a smaller proportion of the cars being purchased by East German residents were used vehicles.
D、Drivers who had driven little or not at all before 1989 accounted for much of the increase in the total distance traveled by cars.
E、Over the same two-year period in East Germany, other road users, such as motorcyclists, bicyclists, and pedestrians, experienced only small increases in traffic fatalities.

D

题目：

Paint on a new airliner is usually applied in two stages: first, a coat of primer, and then a top coat. A new process requires no primer, but instead uses two layers of the same newly developed coating, with each layer of the new coating having the same thickness and weight as a traditional top coat. Using the new process instead of the old process increases the price of a new aircraft considerably.
Which of the following, if true, most strongly indicates that it is in an airline's long-term economic interest to purchase new airliners painted using the new process rather than the old process?

选项:

A、Although most new airliners are still painted using the old process, aircraft manufacturers now offer a purchaser of any new airliner the option of having it painted using the new process instead. 
B、A layer of primer on an airliner weighs more than a layer of the new coating would by an amount large enough to make a difference to that airliner's load-bearing capacity.
C、A single layer of the new coating provides the aluminum skin of the airliner with less protection against corrosion than does a layer of primer of the usual thickness. 
D、Unlike the old process, the new process was originally invented for use on spacecraft, which are subject to extremes of temperature to which airliners are never exposed. 
E、Because the new coating has a viscosity similar to that of a traditional top coat, aircraft manufacturers can apply it using the same equipment as is used for a traditional top coat.

B

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?

A photography dealer ordered 60 Model X cameras to be sold for $250 each, which represents a 20 percent markup over the dealer's initial cost for each camera.
