Some observers have attributed the dramatic growth in temporary employment that occurred in the United States during the 1980s to increased participation in the workforce by certain groups, such as first-time or reentering workers, who supposedly prefer such arrangements. However, statistical analyses reveal that demographic changes in the workforce did not correlate with variations in the total number of temporary workers. Instead, these analyses suggest that factors affecting employers account for the rise in temporary employment. One factor is product demand: temporary employment is favored by employers who are adapting to fluctuating demand for products while at the same time seeking to reduce overall labor costs. Another factor is labor’s reduced bargaining strength, which allows employers more control over the terms of employment. Given the analyses, which reveal that growth in temporary employment now far exceeds the level explainable by recent workforce entry rates of groups said to prefer temporary jobs, firms should be discouraged from creating excessive numbers of temporary positions. Government policymakers should consider mandating benefit coverage for temporary employees, promoting pay equity between temporary and permanent workers, assisting labor unions in organizing temporary workers, and encouraging firms to assign temporary jobs primarily to employees who explicitly indicate that preference.

题目：

The passage suggests which of the following about the workers who took temporary jobs during the 1980s?

选项:

A、Their jobs frequently led to permanent positions within firms.They constituted a less demographically diverse group than has been suggested.
B、They were occasionally involved in actions organized by labor unions.
C、Their pay declined during the decade in comparison with the pay of permanent employees.
D、They did not necessarily prefer temporary employment to permanent employment.

答案:

E

文章：

An experiment was done in which human subjects recognize a pattern within a matrix of abstract designs and then select another design that completes that pattern. The results of the experiment were surprising. The lowest expenditure of energy in neurons in the brain was found in those subjects who performed most successfully in the experiments.

题目：

Which of the following hypotheses best accounts for the findings of the experiment?

选项:

A、The neurons of the brain react less when a subject is trying to recognize patterns than when the subject is doing other kinds of reasoning.Those who performed best in the experiment experienced more satisfaction when working with abstract patterns than did those who performed less well.
B、People who are better at abstract pattern recognition have more energy-efficient neural connections.
C、The energy expenditure of the subjects' brains increases when a design that completes the initially recognized pattern is determined.
D、The task of completing a given design is more capably performed by athletes, whose energy expenditure is lower when they are at rest.

C

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：

Kayla: Many people are reluctant to shop in our neighborhood because street parking is scarce. The city plans to address this by adding parking meters with time limits that ensure that parking spaces are generally available. But this plan will surely backfire—shoppers dislike paying at parking meters, so most will probably drive to other neighborhoods to shop at malls with free parking.

Which of the following, if true, would be the most logically effective rebuttal a proponent of the city’s plan could make to Kayla’s objection?

选项:

A、Most shoppers dislike hunting for scarce street parking spaces much more than they dislike paying for metered parking spaces.
B、The city could post signs with street parking time limits to ensure that parking spaces become available without forcing shoppers to pay at meters.
C、Currently, most shoppers in the neighborhood drive only occasionally to shop at malls in other neighborhoods.
D、The neighborhood already contains a parking lot where shoppers must pay to park.
E、The nearby malls with free parking have no parking time limits to help ensure that parking spaces in their lots become available.

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.

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?
