题目：

The Maxilux car company’s design for its new luxury model, the Max 100, included a special design for the tires that was intended to complement the model’s image. The winning bid for supplying these tires was submitted by Rubco. Analysts concluded that the bid would only just cover Rubco’s costs on the tires, but Rubco executives claim that winning the bid will actually make a profit for the company.

Which of the following, if true, most strongly justifies the claim made by Rubco’s executives?

选项:

A、In any Maxilux model, the spare tire is exactly the same make and model as the tires that are mounted on the wheels.
B、Rubco holds exclusive contracts to supply Maxilux with the tires for a number of other models made by Maxilux.
C、The production facilities for the Max 100 and those for the tires to be supplied by Rubco are located very near each other.
D、When people who have purchased a carefully designed luxury automobile need to replace a worn part of it, they almost invariably replace it with a part of exactly the same make and type.
E、When Maxilux awarded the tire contract to Rubco, the only criterion on which Rubco’s bid was clearly ahead of its competitors’ bids was price.

题目：

Although there is no record of poet Edmund Spenser’s parentage, we do know that as a youth Spenser attended the Merchant Tailors’ School in London for a period between 1560 and 1570. Records from this time indicate that the Merchant Tailors’ Guild then had only three members named Spenser: Robert Spenser, listed as a gentleman; Nicholas Spenser, elected the Guild’s Warden in 1568; and John Spenser, listed as a “journeyman cloth-maker.” Of these, the last was likely the least affluent of the three—and most likely Edmund’s father, since school accounting records list Edmund as a scholar who attended the school at a reduced fee.

Which of the following is an assumption on which the argument depends?

选项:

A、Anybody in sixteenth century London who made clothing professionally would have had to be a member of the Merchant Tailors’ Guild.
B、The fact that Edmund Spenser attended the Merchant Tailors’ School did not necessarily mean that he planned to become a tailor.
C、No member of the Guild could become Guild warden in sixteenth century London unless he was a gentleman.
D、Most of those whose fathers were members of the Merchant Tailors’ Guild were students at the Merchant Tailors’ School.
E、The Merchant Tailors’ School did not reduce its fees for the children of the more affluent Guild members.

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.

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.

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.

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. Of the cameras ordered, 6 were never sold and were returned to the manufacturer for a refund of 50 percent of the dealer's initial cost. What was the dealer's approximate profit or loss as a percent of the dealer's initial cost for the 60 cameras?
