单选题{{B}}Passage 3{{/B}} Often referred to as "the heart of a factoring organization", the credit department is responsible for granting credit to clients' customers and for collecting the accounts receivable purchased by the factor. When factored clients submit customer orders for credit approval, the credit department analyzes the financial condition and credit worthiness of the customer, and then makes a decision to approve or decline the order. The department must then monitor the condition of approved customers and collect all due receivables. Careful credit checking and effective collection procedures in this department can greatly reduce the risks inherent in factoring. As the head of the credit department, the credit manager is responsible for seeing that the department operates effectively. He must develop the factor's credit policies in consultation with senior factoring associates, and he is in overall command of everything from credit and collections to bankruptcy and liquidations. If the factor is a commercial bank division, the credit manager is a bank's vice president, and credit policy must also be approved by top management of the bank. Assisting the credit manager may be several supervisors who have credit responsibilities of their own and who also oversee the analysis and approval of customer orders by the credit specialists. Credit supervisors typically spend about eighty percent of their time handling large customer orders. If a customer order exceeds a supervisor's credit authority, he is responsible for making recommendations to the credit manager. A supervisor also reviews a subordinate's credit decision if the subordinate is unsure of the extent of the credit risk or if a client questions a particular credit decision. In extremely large credit exposures, supervisors bear the responsibility for analyzing the credit position of the customers and deciding on credit limits. To do this, they must regularly obtain current data from various credit information sources. They must also have extensive contact with each customer to determine operational performance and progress. Frequently, supervisors are called upon to give advice on what should be done to improve a company's financial condition. Meeting all these responsibilities requires that each supervisor continuously observe and study the industries with which he is concerned, so that he is capable of anticipating market changes which may affect his accounts. A supervisor's major challenge is to maintain a fine balance between the demands of clients that all their customer orders be approved and the questionable financial position of some of the customers. In reviewing any credit decision, a supervisor must be capable of weighing a variety of elements, including the possibility of losing the client, the customer's credit position, and the extent of any possible loss.

单选题The future of space exploration depends on many things. It depends on how technology evolves, how political forces shape competition and partnerships between nations, and how important the public feels space exploration is. The near future will see the continuation of human space fright in Earth"s orbit and unpiloted space flight within the solar system. Piloted space flight to other planets, or even back to the moon, still seems far away. Any flight to other solar systems is even more distant, but a huge advance in space technology could drive space exploration into realms currently explored only by science fiction. The 1968 film 2001: A Space Odyssey depicted commercial shuttles flying to and from a giant wheel-shaped space station in orbit around Earth, bases on the moon, and a piloted mission to Jupiter. The real space activities of 2001 will not match this cinematic vision, but the 21st century will see a continuation of efforts to transform humanity into a spacefaring species. Perhaps the most difficult problem space planners face is how to finance a vigorous program of piloted space exploration, in Earth"s orbit and beyond. In 1998 no single government or international enterprise had plans to send people back to the moon, much less to Mars. Such missions are unlikely to happen until the perceived value exceeds their cost. One belief shared by a number of space exploration experts is that future lunar and Martian expeditions should be aimed at creating permanent settlements. The residents of such outposts would have to "live off the land," obtaining such necessities as oxygen and water from the harsh environment. On the moon, pioneers could obtain oxygen by heating lunar soil. In 1998 the Lunar Prospector discovered evidence of significant deposits of ice, a valuable resource for settlers, mixed with soil at the lunar poles. On Mars, oxygen could be extracted from the atmosphere and water could come from buried deposits of ice. The future of piloted lunar and planetary exploration remains largely unknown. Most space exploration scientists believe that people will be on the moon and Mars by the middle of the 21st century, but how they get there, and the nature of their visits, is a subject of continuing debate. Clearly, key advances will need to be made in lowering the cost of getting people off Earth, the first step in any human voyage to other worlds.

单选题David Landes, author of The Wealth and Poverty of Nations: Why Some Are So Rich and Some So Poor, credits the world's economics and social progress over the last thousand years to "Western civilization and its dissemination." The reason, he believes, is that Europeans invented systematic economic development. Landes adds that two unique aspects of Europeans culture were crucial ingredient in Europe's economic growth. First, Landes espouses a generalized form of Max Weber's thesis that the values of work, initiative, and investment made the difference for Europe. Despite his emphasis on science, Landes does not stress the notion of rationality as such. In his view, "what counts is work, thrift, honesty, patience, tenacity." The only route to economic success for individuals or states is working hard, spending less than you earn, and investing the rest in productive capacity. This is the fundamental explanation of the problem posed by his hook's subtitle: "Why Some Are So Rich and Some So Poor." For historical reasons—an emphasis on private property, an experience of political pluralism, a temperate climate, an urban style--Europeans have, on balance, followed those practices and therefore have prospered. Second, and perhaps most important, Europeans were learners. They "learned rather greedily," as Joel Mokyr put it in a review of Landes's book. Even if Europeans possessed indigenous technologies that gave them an advantage (spectacles, for example), as Landes believes they did, their most vital asset was the ability to assimilate knowledge from around the world and put it to use—as in borrowing the concept of zero and rediscovering Aristotle's Logic from the Arabs and taking paper and gunpowder from the Chinese via the Muslim world. Landes argues that a systematic resistance to learning from other cultures had become the greatest handicap of the Chinese by the eighteenth century and remains the greatest handicap of Arab countries today. Although his analysis of Europeans expansion is almost nonexistent, Landes does not argue that Europeans were beneficent bearers of civilization to a benighted world. Rather, he relies on his own common- sense law: "When one group is strong enough to push another around and stands to gain by it, it will do so." In contrast to the new school of world historians, Landes believes that specific cultural values enabled technological advances that in turn made some Europeans strong enough to dominate people in other parts of the world. Europeans therefore proceeded to do so with great viciousness and cruelty. By focusing on their victimization in this process, Landes holds, some postcolonial states have wasted energy that could have been put into productive work and investment. If one could sum up Landes's advice to these states in one sentence, it might be "Stop whining and get to work." This is particularly important, indeed hopeful, advice, he would argue, because success is not permanent. Advantages are not fixed, gains from trade are unequal, and different societies react differently to market signals. Therefore, not only is there hope for undeveloped countries, but developed countries have little cause to be complacent, because the current situation "will press hard" on them. The thrust of studies like Landes's is to identify those distinctive features of European civilization that lie behind Europe's rise to power and the creation of modernity more generally. Other historians have placed a greater emphasis on such features as liberty, individualism, and Christianity. In a review essay, the art historian Craig Clunas listed some of the less well known linkages that have been proposed between Western culture and modernity, including the propensities to think quantitatively, enjoy pornography, and consume sugar. All such proposals assume the fundamental aptness of the question: What elements of Europeans civilization led to European success? It is a short leap from this assumption to outright triumphalism. The paradigmatic book of this school is, of course, The End of History and the Last Man, in which Francis Fukuyama argues that after the collapse of Nazism in the twentieth century, the only remaining model for human organization in the industrial and communications ages is a combination of market economics and limited, pluralist, democratic government.
