Questions 63 to 66 are based on the following passage:The Intel Science Talent Search, the most prestigious high school science contest in the nation, was launched to identify young scientific talent, and it has been doing so with remarkable precision since 1941. Every year, approximately 1,700 students from around the country polish off projects they have been working on for as long as two years, and send in a report to the contest officials. Simply entering the contest is an impressive achievement for a high school junior. It means that the student has spent hundreds of hours probing a scientific question or testing a theory about which he has written a scientific paper of near-professional quality. The top 300 students become semifinals, and from this group, 40 are selected to bring their projects to Washington. Ten projects are then selected as the best in the final round of judging. The 40 finalists get at least $7,500 for their efforts, and the top student receives a $100,000 scholarship. Most of the winners, from semifinals up, are guaranteed admission to the college of their choice.From the start, this contest was different from traditional science fairs. Its goal was not simply to choose the best project but to locate the best potential scientists. The distinction is an important one. The contest has a number of features that test the mettle of the students as well as the projects. It endeavors to explore the nimbleness and originality of the minds behind the projects, rather than just rewarding the boldness of the experiment. The contest’s underlying philosophy is that students discover their scientific talents by working on science, not by listening to lectures in a classroom. From the context we may figure out that the expression “polish off” in line 4 of paragraph 1 most probably means（）.
Questions 59 to 62 are based on the following passage:NegotiationThe increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts.Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation.In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal purveyor of information and cash, an image that succeeds only in undermining the negotiation.In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while subverting the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator.Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. The word “undermining” in the last sentence of paragraph 3 is closest in meaning to（）.
