单选题Which of the following makes the demonstration most persuasive?

单选题College graduates are now leaving school with not only a diploma, but also with more debt than in any other period in history. According to the College Board, average financial aid per full time equivalent student adjusted for inflation, has almost doubled in the last decade. Additionally, not only is the average student debt load higher, but also the number of loans originated increased by nearly fourfold. Thus student lending has increased in breadth as well as depth, doubly impacting the financial situations of those students who must depend on student loans to finance their education. Furthermore, these figures no doubt understate the true level of indebtedness incurred by students and their families since some undoubtedly finance part of their education and living expenses through the use of consumer loans, home equity loans or credit cards. Thus, the already huge burden of student loan debt incurred by students and their families is exacerbated by financial obligations from other sources. This situation is the outcome of a precarious combination of easy credit, thanks to card issuers who are eager to tap into this lucrative market, financial naiveté on the part of students, and a sense on both sides that, if worse comes to worse, mommy and daddy will step in and set things right. All combine to make credit a tempting lure to students strapped for cash. While credit still remain a virtual element for the financing of many students' education at expensive colleges, its implications must carefully weighed and considered, lest the cash-poor student find himself with more that he bargained for. Most students in the United States attend colleges whose tuition does not exceed $15,000, however. Nevertheless, rising prices, combined with stagnant income gains among low-and moderate-income families, have made it difficult if not impossible for a student from a family of such an income level, a student who has the most to gain from a college education, to attend college without significantly adding to the financial burden of his or her family. While student loans still remain a vital element for the financing of many students' education at expensive colleges, its implications must be carefully weighed and considered, lest the cash-poor student find himself with more than he bargained for.

单选题The majority of successful senior managers do not closely follow the classical rational model of first clarifying goals, assessing the problem, formulating options, estimating likelihood of success, making a decision, and only then taking action to implement the decision. Rather, in their day-by-day tactical activities, these senior executives rely on what is vaguely termed "intuition" to manage a network of interrelated problems that require them to deal with ambiguity, inconsistency, novelty, and surprise; and to integrate action into the process of thinking. Generations of writers on management have recognized that some practicing managers rely heavily on intuition. In general, however, such writers display a poor grasp of what intuition is. Some see it as the opposite of rationality; others view it as an excuse of capriciousness. Isenberg's recent research on the cognitive processes of senior managers reveals that managers' intuition is neither of these. Rather, senior managers use intuition in at least five distinct ways. First, they intuitively sense when a problem exists. Second, managers rely on intuition to perform well-learned behavior patterns rapidly. This intuition is not arbitrary or irrational, but is based on years of painstaking practice and personal experience that build skills. A third function of intuition is to synthesize isolated bits of data and practice into an integrated picture, often in an "Aha!" experience. Fourth, some managers use intuition as a check on the results of more rational analysis. Most senior executives are familiar with the formal decision analysis models and tools, and those who use such systematic methods for reaching decisions are occasionally suspicious of solutions suggested by these methods which run counter to their sense of the correct course of action. Finally, managers can use intuition to bypass in-depth analysis and move rapidly to find out a plausible solution. Used in this way, intuition is an almost instantaneous cognitive process in which a manager recognizes familiar patterns. One of the implications of the intuitive style of executive management is that "thinking" is inseparable from acting. Since managers often "know" what is right before they can analyze and explain it, they frequently act first and explain later. Analysis is invariably tied to action in thinking/acting cycles, in which managers develop thoughts about their companies and organizations not by analyzing a problematic situation and then acting, but by acting and analyzing in close concert. Given the great uncertainty of many of the management issues that they face, senior managers often initiate a course of action simply to learn more about an issue. They then use the results of the action to develop a more complete understanding of the issue. One implication of thinking/acting cycles is that action is often part of defining the problem, not just of implementing the solution.

Coffee is worth approximately $ 50-60bn each year in terms of world sales. It is a truly international commodity, and today more than 50 countries in the world grow coffee beans. This makes the coffee industry fairly universal, according to Pablo Dubois, head of the International Coffee Organisation (ICO), based in London. ICO organization helps coffee producers and promotes coffee consumption worldwide. ICO estimates that world production next year will reach 97.5 million bags, 11.3 million bags higher than the current year. The main reason for this is higher Brazilian output as production recovers from weather damage to crops. 41．______In 1994 Brazil was responsible for 25% of world production, Colombia was next with 13.4%, Indonesia had 7.5%, Mexico 4.7%, Guatemala 3.8% and Ethiopia and Vietnam were equal with 3.4%. Coffee is a tough crop, and can be grown in areas where it is difficult or impossible to grow other crops. It is cultivated in mountain regions which can only be reached by animal transport, and in other difficult areas where modern agricultural equipment cannot be used. 42． ______ICO is active in educating farmers about avoiding disease and dealing with problems when they occur. The distribution chain varies from country to country, explains Pablo Dubois. In most countries the smaller farmers sell their crop to a local trader, who then sells it on to exporters. 43． ______Larger coffee growers, for example, frequently export directly. Some countries, like Vietnam, have special government marketing organizations for coffee. Coffee prices often vary greatly from one year to the next. In 1997, for example, there was a large rise in the world price, which was immediately felt by the consumer. 44．______ In some of these countries, this can amount to as much as 50% of all export earnings. In the opinion of Pablo Dubois, the biggest problem for his organisation is to create greater consumer awareness of the different varieties of coffee and different ways of preparing it. In North America, most consumers already have above average knowledge Of the range available. 45．______It is also encouraging environmentally friendly coffee production, and last year's seminar on coffee and the environment created a lot of interest. The future looks bright for the coffee industry. It is estimated that consumption over the next few years will continue to rise steadily. New markets like Eastern Europe and China are expected to develop fast. [A] However, disease is always problem for coffee production, as we can see in some parts of South America at the moment. [B] Because the amount of coffee demand is on a high rise. [C] ICO is therefore concentrating its promotional activities on Russia and China. [D] As the largest producing country, Brazil is particularly important in the coffee world. [E] Rising prices always result in a drop in sales, which will have a bad effect on those developing countries, which are highly dependent on foreign exchange from coffee exports. [F] There are, however, other distribution systems. [G] Almost all the coffee growers share the same distribution channel.

单选题For the first time in history more people live in towns than in the country. In Britain this has had a curious result. While polls show Britons rate "the countryside" alongside the royal family, Shakespeare and the National Health Service (NHS) as what makes them proudest of their country, this has limited political support. A century ago Octavia Hill launched the National Trust not to rescue stylish houses but to save "the beauty of natural places for everyone forever." It was specifically to provide city dwellers with spaces for leisure where they could experience "a refreshing air." Hill"s pressure later led to the creation of national parks and green belts. They don"t make countryside any more, and every year concrete consumes more of it. It needs constant guardianship. At the next election none of the big parties seem likely to endorse this sentiment. The Conservatives" planning reform explicitly gives rural development priority over conservation, even authorising "off-plan" building where local people might object. The concept of sustainable development has been defined as profitable. Labour likewise wants to discontinue local planning where councils oppose development. The Liberal Democrats are silent. Only Ukip, sensing its chance, has sided with those pleading for a more considered approach to using green land. Its Campaign to Protect Rural England struck terror into many local Conservative parties. The sensible place to build new houses, factories and offices is where people are, in cities and towns where infrastructure is in place. The London agents Stirling Ackroyd recently identified enough sites for half a million houses in the London area alone, with no intrusion on green belt. what is true of London is even truer of the provinces. The idea that "housing crisis" equals "concreted meadows" is pure lobby talk. The issue is not the need for more houses but, as always, where to put them. Under lobby pressure, George Osborne favours rural new-build against urban renovation and renewal. He favours out-of-town shopping sites against high streets. This is not a free market but a biased one. Rural towns and villages have grown and will always grow. They do so best where building sticks to their edges and respects their character. We do not ruin ur ban conservation areas. Why ruin rural ones? Development should be planned, not let rip. After the Netherlands, Britain is Europe"s most crowded country. Half a century of town and country planning has enabled it to retain an enviable rural coherence, while still permitting low-density urban living. There is no doubt of the alternative—the corrupted landscapes of southern Portugal, Spain or Ireland. Avoiding this rather than promoting it should unite the left and right of the political spectrum.

单选题Few insects have inspired as much fear and hatred as the diminutive fire ants, less than half an inch long but living in colonies of more than 250,000 others. Everyone in the southern United States gets to know fire ants sooner or later by painful experience. Fire ants live in large earthen mounds and are true social insects--that means they have a caste system ( division of labor), with a specialized caste that lays eggs (queen) and a worker caste of sterile females. There are several reasons that they are considered pests. About 60% of people living in areas where fire ants occur are stung every year. Of these, about 1% have some degree of allergic reaction ( called anaphylaxis) to the sting. Their large mounds are unsightly and can damage mowing equipment. Fire ants sometimes enter electrical and mechanical equipment and can short out switches or chew through insulation. Finally. as fire ants move into new areas, they reduce diversity of native ants and prey on larger animals such as ground-nesting birds and turtles. Even though fire ants are pests in many circumstances, they can actually be beneficial in others. There is evidence that their predatory activities can reduce the numbers of some other important pests. In cotton, for example, they prey on important pests that eat cotton plants such as bollworms and budworms. In Louisiana sugarcane, an insect called the sugarcane borer used to be a very important pest before fire ants arrived and began preying on it. Fire ants also prey on ticks and fleas. Whether fire ants are considered pest or not depend on where they are found, but one thing is sure—we had best get used to living with them. Eradication attempts in the 1960s and 1970s failed for a number of reasons, and scientists generally agree that complete elimination of fire ants from the United States is not possible. A new, long-term approach to reducing fire ant populations Involves classical biological control. When fire ants were accidentally brought to the United States, most of their parasites and diseases were not. Classical biological control involves identifying parasites and diseases specific to fire ants in South America, testing them to be sure that they don ' t attack or infect native plants or animals and establishing them in the Introduced fire ant population In the United States. Since fire ants are about 5 to 7 times more abundant here than in South America, scientists hope to reduce their numbers using this approach.
