题目：
Generally scientists enter their field with the goal of doing important new research and accept as their colleagues those with similar motivation. Therefore, when any scientist wins renown as an expounder of science to general audiences, most other scientists conclude that this popularizer should no longer be regarded as a true colleague.
The explanation offered above for the low esteem in which scientific popularizers are held by research scientists assumes that
选项:
A、serious scientific research is not a solitary activity, but relies on active cooperation among a group of colleagues
B、research scientists tend not to regard as colleagues those scientists whose renown they envy
C、a scientist can become a famous popularizer without having completed any important research
D、research scientists believe that those who are well known as popularizers of science are not motivated to do important new research
E、no important new research can be accessible to or accurately assessed by those who are not themselves scientists

题目：
A newly discovered painting seems to be the work of one of two seventeenth-century artists, either the northern German Johannes Drechen or the Frenchman Louis Birelle, who sometimes painted in the same style as Drechen. Analysis of the carved picture frame, which has been identified as the painting’s original seventeenth-century frame, showed that it is made of wood found widely in northern Germany at the time, but rare in the part of France where Birelle lived. This shows that the painting is most likely the work of Drechen.
Which of the following is an assumption that the argument requires?
Which of the following is an assumption that the argument requires?
选项:
A、The frame was made from wood local to the region where the picture was painted.
B、Drechen is unlikely to have ever visited the home region of Birelle in France.
C、Sometimes a painting so resembles others of its era that no expert is able to confidently decide who painted it.
D、The painter of the picture chose the frame for the picture.
E、The carving style of the picture frame is not typical of any specific region of Europe.

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 the modernization of the telephone exchange is supported by information in the passage?
选项:
A、The new technology reduced the role of managers in labor negotiations.
B、The modernization was implemented without the consent of the employees directly affected by it.
C、The modernization had an impact that went significantly beyond maintenance routines.
D、Some of the maintenance workers felt victimized by the new technology.
E、The modernization gave credence to the view of advocates of social constructivism.

文章：
Citing the fact that the real gross domestic product (GDP) per capita was higher in 1997 than ever before, some journalists have argued that the United States economy performed ideally in 1997. However, the real GDP is almost always higher than ever before; it falls only during recessions. One point these journalists overlooked is that in 1997, as in the twenty-four years immediately preceding it, the real GDP per capita grew nearly one-half percent a year more slowly than it had on average between 1873 and 1973. Were the 1997 economy as robust as claimed, the growth rate of real GDP per capita in 1997 would have surpassed the average growth rate of real GDP per capita between 1873 and 1973 because over fifty percent of the population worked for wages in 1997 whereas only forty percent worked for wages between 1873 and 1973. If the growth rate of labor productivity (output per hour of goods and services) in 1997 had equaled its average growth rate between 1873 and 1973 of more than two percent, then, given the proportionately larger workforce that existed in 1997, real GDP per capita in 1997 would have been higher than it actually was, since output is a major factor in GDP. However, because labor productivity grew by only one percent in 1997, real GDP per capita grew more slowly in 1997 than it had on average between 1873 and 1973.

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?
