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.

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.

E

If the statements above are true, which of the following must also be true about United States residents who took trips for pleasure in 1997 ?

选项:

A、Most of those who traveled by airplane did so because the airfare to their destination was lower than the cost of other available means of transportation.
B、Most of those who traveled by airplane did so because other means of transportation to their destination were unavailable.
C、Per mile traveled, those who traveled by airplane tended to spend more on transportation to their destination than did those who used other means of transportation.

文章：

Historians have identified two dominant currents in the Russian women's movement of the late tsarist period.  "Bourgeois" feminism, so called by its more radical opponents, emphasized "individualist" feminist goals such as access to education, career opportunities, and legal equality.  "Socialist" feminists, by contrast, emphasized class, rather than gender, as the principal source of women's inequality and oppression, and socialist revolution, not legal reform, as the only road to emancipation and equality.
 
However, despite antagonism between bourgeois feminists and socialist feminists, the two movements shared certain underlying beliefs.  Both regarded paid labor as the principal means by which women might attain emancipation:  participation in the workplace and economic self-sufficiency, they believed, would make women socially useful and therefore deserving of equality with men.  Both groups also recognized the enormous difficulties women faced when they combined paid labor with motherhood.  In fact, at the First All-Russian Women's Congress in 1908, most participants advocated maternity insurance and paid maternity leave, although the intense hostility between some socialists and bourgeois feminists at the Congress made it difficult for them to recognize these areas of agreement.  Finally, socialist feminists and most bourgeois feminists concurred in subordinating women's emancipation to what they considered the more important goal of liberating the entire Russian population from political oppression, economic backwardness, and social injustice.

题目：

According to the passage, Russian socialists within the women's movement and most bourgeois feminists disagreed about which of the following?

选项:

A、Whether legal reform was central to the achievement of feminist goals
B、Whether paid employment was important for the achievement of equality
C、Whether maternity insurance was desirable for working mothers
D、Whether working mothers faced obstacles
E、Whether women's emancipation should be subordinated to the liberation of the Russian population

A

文章：

During the nineteenth century, occupational information about women that was provided by the United States census--a population count conducted each decade--became more detailed and precise in response to social changes.  Through 1840, simple enumeration by household mirrored a home-based agricultural economy and hierarchical social order:  the head of the household (presumed male or absent) was specified by name, whereas other household members were only indicated by the total number of persons counted in various categories, including occupational categories.  Like farms, most enterprises were family-run, so that the census measured economic activity as an attribute of the entire household, rather than of individuals.
 
The 1850 census, partly responding to antislavery and women's rights movements, initiated the collection of specific information about each individual in a household.  Not until 1870 was occupational information analyzed by gender:  the census superintendent reported 1.8 million women employed outside the home in "gainful and reputable occupations." In addition, he arbitrarily attributed to each family one woman "keeping house." Overlap between the two groups was not calculated until 1890, when the rapid entry of women into the paid labor force and social issues arising from industrialization were causing women's advocates and women statisticians to press for more thorough and accurate accounting of women's occupations and wages.

题目：

Each of the following aspects of nineteenth-century United States censuses is mentioned in the passage EXCEPT the

选项:

A、year in which data on occupations began to be analyzed by gender
B、year in which specific information began to be collected on individuals in addition to the head of the household
C、year in which overlap between women employed outside the home and women keeping house was first calculated
D、way in which the 1890 census measured women's income levels and educational backgrounds
E、way in which household members were counted in the 1840 census

D

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.
