题目：
Frobisher, a sixteenth-century English explorer, had soil samples from Canada's Kodlunarn Island examined for gold content. Because high gold content was reported, Elizabeth I funded two mining expeditions. Neither expedition found any gold there. Modern analysis of the island's soil indicates a very low gold content. Thus the methods used to determine the gold content of Frobisher's samples must have been inaccurate.
选项:
A、The gold content of the soil on Kodlunarn Island is much lower today than it was in the sixteenth century.
B、The two mining expeditions funded by Elizabeth I did not mine the same part of Kodlunarn Island.
C、The methods used to assess gold content of the soil samples provided by Frobisher were different from those generally used in the sixteenth century.
D、Frobisher did not have soil samples from any other Canadian island examined for gold content.
E、Gold was not added to the soil samples collected by Frobisher before the samples were examined.

题目：
Hollywood restaurant is replacing some of its standard tables with tall tables and stools. The restaurant already fills every available seat during its operating hours, and the change in seating arrangements will not result in an increase in the restaurant’s seating capacity. Nonetheless, the restaurant’s management expects revenue to increase as a result of the seating change without any concurrent change in menu, prices, or operating hours.
Which of the following, if true, provides the best reason for the expectation?
Which of the following, if true, provides the best reason for the expectation?
选项:
A、One of the taller tables takes up less floor space than one of the standard tables.
B、Diners seated on stools typically do not linger over dinner as long as diners seated at standard tables.
C、Since the restaurant will replace only some of its standard tables, it can continue to accommodate customers who do not care for the taller tables.
D、Few diners are likely to avoid the restaurant because of the new seating arrangement.
E、The standard tables being replaced by tall tables would otherwise have to be replaced with new standard tables at a greater expense.

文章：
| Line | Jon Clark’s study of the effect of the modernization |
| of a telephone exchange on exchange maintenance | |
| work and workers is a solid contribution to a debate | |
| that encompasses two lively issues in the history and | |
| (5) | sociology of technology: technological determinism |
| and social constructivism. | |
| Clark makes the point that the characteristics of a | |
| technology have a decisive influence on job skills and | |
| work organization. Put more strongly, technology can | |
| (10) | be a primary determinant of social and managerial |
| organization. Clark believes this possibility has | |
| been obscured by the recent sociological fashion, | |
| exemplified by Braverman’s analysis, that emphasizes | |
| the way machinery reflects social choices. For | |
| (15) | Braverman, the shape of a technological system is |
| subordinate to the manager’s desire to wrest control | |
| of the labor process from the workers. Technological | |
| change is construed as the outcome of negotiations | |
| among interested parties who seek to incorporate | |
| (20) | their own interests into the design and configuration |
| of the machinery. This position represents the new | |
| mainstream called social constructivism. | |
| The constructivists gain acceptance by | |
| misrepresenting technological determinism: | |
| (25) | technological determinists are supposed to believe, |
| for example, that machinery imposes appropriate | |
| forms of order on society. The alternative to | |
| constructivism, in other words, is to view technology | |
| as existing outside society, capable of directly | |
| (30) | influencing skills and work organization. |
| Clark refutes the extremes of the constructivists | |
| by both theoretical and empirical arguments. | |
| Theoretically he defines “technology” in terms of | |
| relationships between social and technical variables. | |
| (35) | Attempts to reduce the meaning of technology to |
| cold, hard metal are bound to fail, for machinery is | |
| just scrap unless it is organized functionally and | |
| supported by appropriate systems of operation and | |
| maintenance. At the empirical level Clark shows how | |
| (40) | a change at the telephone exchange from |
| maintenance-intensive electromechanical switches | |
| to semielectronic switching systems altered work | |
| tasks, skills, training opportunities, administration, | |
| and organization of workers. Some changes Clark | |
| (45) | attributes to the particular way management and |
| labor unions negotiated the introduction of the | |
| technology, whereas others are seen as arising from | |
| the capabilities and nature of the technology itself. | |
| Thus Clark helps answer the question: “When is | |
| (50) | social choice decisive and when are the concrete |
| characteristics of technology more important?” |
题目：
Which of the following statements about Clark’s study of the telephone exchange can be inferred from information in the passage?
选项:
A、Clark’s reason for undertaking the study was to undermine Braverman’s analysis of the function of technology.
B、Clark’s study suggests that the implementation of technology should be discussed in the context of conflict between labor and management.
C、Clark examined the impact of changes in the technology of switching at the exchange in terms of overall operations and organization.
D、Clark concluded that the implementation of new switching technology was equally beneficial to management and labor.
E、Clark’s analysis of the change in switching systems applies only narrowly to the situation at the particular exchange that he studied.

题目：
Many athletes inhale pure oxygen after exercise in an attempt to increase muscular reabsorption of oxygen. Measured continuously after exercise, however, the blood lactate levels of athletes who inhale pure oxygen are practically identical, on average, to those of athletes who breathe normal air. The lower the blood lactate level is, the higher the muscular reabsorption of oxygen is.
If the statements above are all true, they most strongly support which of the following conclusions?

Although the industrial union organizations that emerged under the banner of the Congress of Industrial Organizations (CIO) in the 1930s and 1940s embraced the principles of nondiscrimination and inclusion, the role of women within unions reflected the prevailing gender ideology of the period. Elizabeth Faue's study of the labor movement in Minneapolis argues that women were marginalized by union bureaucratization and by the separation of unions from the community politics from which industrial unionism had emerged. Faue stresses the importance of women's contribution to the development of unions at the community level, contributions that made women's ultimate fate within the city's labor movement all the more poignant: as unions reached the peak of their strength in the 1940s, the community base that had made their success possible and to which women's contributions were so vital became increasingly irrelevant to unions' institutional life.
In her study of CIO industrial unions from the 1930s to the 1970s, Nancy F. Gabin also acknowledges the pervasive male domination in the unions, but maintains that women workers were able to create a political space within some unions to advance their interests as women. Gabin shows that, despite the unions' tendency to marginalize women's issues, working women's demands were a constant undercurrent within the union, and she stresses the links between the unions' women activists and the wave of feminism that emerged in the 1960s.

题目：
Jennifer: Video rental outlets in Centerville together handled 10,000 fewer video rentals in 1994 than in 1993. The decline in rentals was probably due almost entirely to the February 1994 opening of Videorama, the first and only video rental outlet in the area that, in addition to renting videos, also sold them cheaply.
Brad: There must be another explanation: as you yourself said, the decline was on the order of 10,000 rentals. Yet Videorama sold only 4,000 videos in 1994.
Which of the following, if true, would most seriously weaken the force of the objection that Brad presents to Jennifer's explanation?

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?
