文章：
The experience of British business in Iran between the 1860's and the 1970's is one example of the changing importance of British enterprise in Asia as a whole. Before 1914 British business established and dominated Iran's modern industrial and financial sector; in the 1920's this domination began to wane; by the 1960's British enterprise was of little importance in the Iranian economy. While in Japan and India the decline of British business was primarily a function of the rise of strong indigenous business groups, in Iran, by contrast, the government played a large role in both challenging British commercial interests and stimulating locally owned enterprise. Periodic surges of intense Iranian economic nationalism must be understood partly as a reaction to the close relations between British business in Iran and the British government. In retrospect, it is possible to see the uneasy and ambiguous nature of this relationship. It is true that the British Imperial Bank in Iran was never entirely a tool of the British government, and that the Anglo-Iranian Oil Company did not take its orders from the British government, despite the 51 percent government shareholding. However, the relationship between British business and the British government was sufficiently close that many Iranians understandably viewed the oil company and the bank as symbols of a British imperialist policy.
题目：
The passage suggests which of the following about British business in Japan and India as compared to British business in Iran?
选项:
A、British business in Japan and India received less support from the British government than did British business in Iran.
B、During the early twentieth century, British business played less of a role in the Japanese and Indian economy than it did in the Iranian economy.
C、The governments of Japan and India played less of a role in the changing status of British business than did the government of Iran.
D、The types of enterprises conducted by the British in Japan and India were significantly different from the enterprises conducted by the British in Iran.
E、British business in Japan and India declined more gradually than did British business in Iran.

文章：
Most students arrive at [college] using "discrete, concrete, and absolute categories to understand people, knowledge, and values." These students live with a dualistic view, seeing "the world in polar terms of we-right-good vs. other-wrong-bad." These students cannot acknowledge the existence of more than one point of view toward any issue. There is one "right" way. And because these absolutes are assumed by or imposed on the individual from external authority, they cannot be personally substantiated or authenticated by experience. These students are slaves to the generalizations of their authorities. An eye for an eye! Capital punishment is apt justice for murder. The Bible says so.
Most students break through the dualistic stage to another equally frustrating stage—multiplicity. Within this stage, students see a variety of ways to deal with any given topic or problem. However, while these students accept multiple points of view, they are unable to evaluate or justify them. To have an opinion is everyone’s right. While students in the dualistic stage are unable to produce evidence to support what they consider to be self-evident absolutes, students in the multiplistic stage are unable to connect instances into coherent generalizations. Every assertion, every point, is valid. In their democracy they are directionless. Capital punishment? What sense is there in answering one murder with another?
The third stage of development finds students living in a world of relativism. Knowledge is relative: right and wrong depend on the context. No longer recognizing the validity of each individual idea or action, relativists examine everything to find its place in an overall framework. While the multiplist views the world as unconnected, almost random, the relativist seeks always to place phenomena into coherent larger patterns. Students in this stage view the world analytically. They appreciate authority for its expertise, using it to defend their own generalizations. In addition, they accept or reject ostensible authority after systematically evaluating its validity. In this stage, however, students resist decision making. Suffering the ambivalence of finding several consistent and acceptable alternatives, they are almost overwhelmed by diversity and need means for managing it. Capital punishment is appropriate justice—in some instances.
In the final stage students manage diversity through individual commitment. Students do not deny relativism. Rather they assert an identity by forming commitments and assuming responsibility for them. They gather personal experience into a coherent framework, abstract principles to guide their actions, and use these principles to discipline and govern their thoughts and actions. The individual has chosen to join a particular community and agrees to live by its tenets. The accused has had the benefit of due process to guard his civil rights, a jury of peers has found him guilty, and the state has the right to end his life. This is a principle my community and I endorse.

选项:
A、A. Committed thinkers are not very sure of their positions.

D、D. Dualistic thinkers have thought out the reasons for taking their positions.
E、E. Dualistic thinkers fear the power of authority.

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?
