1. 大全TEST21 -1 One state adds a 7 percent sales tax to the price of most products purchased within its jurisdiction. This tax, therefore, if viewed as tax on income, has the reverse effect of the federal income tax: the lower the income, the higher the annual percentage rate at which the income is taxed. The conclusion above would be properly drawn if which of the following were assumed as a premise? Answer: The amount of money citizens spend on products subject to the state tax tends to be equal across income levels. 2. 大全TEST21-2 The average age of chief executive officers (CEO’s) in a large sample of companies is 57. The average age of CEO’s in those same companies 20 years ago was approximately eight years younger. On the basis of those data, it can be concluded that CEO’s in general tend to be older now. Which of the following casts the most doubt on the conclusion drawn above? Answer: The information is based only on companies that have been operating for at least 20 years. 3. 大全TEST21-6 Radio interferometry is a technique for studying details of celestial objects that combines signals intercepted by widely spaced radio telescopes. This technique requires ultraprecise timing, exact knowledge of the locations of the telescopes, and sophisticated computer programs. The successful interferometric linking of an Earth-based radio telescope with a radio telescope on an orbiting satellite was therefore a significant technological accomplishment. Which of the following can be correctly inferred from the statements above? Answer: The location of an orbiting satellite relative to locations on Earth can be well enough known for interferometric purposes. 4. 大全TEST21 The value of a product is determined by the ratio of its quality to its price. The higher the value of a product, the better will be its competitive position. Therefore, either increasing the quality or lowering the price of a given product will increase the likelihood that consumer will select that product rather than a competing one. Which of the following, if true, would most strengthen the conclusion drawn above? Answer: Consumers’ perceptions of the quality of a product are based on the actual quality of the product.
AA: 我们来写机经吧!~oh, yeah! JJ 第二篇~ The following appeared in a presentation by the chief production manager of a machine parts manufacturing company at a management meeting: “Our factory in Cookville is our most advanced and efficient. It is capable of producing ten drill bits for each dollar of production costs, whereas none of our other factories can produce more than seven drill bits per dollar of production costs. Therefore, we can reduce our overall drill bit production costs by devoting the Cookville factory entirely to drill bit production. Since reducing the production costs of individual machine parts is the only way to achieve our larger goal of reducing our overall production costs, dedicating the Cookville factory entirely to drill bit production and shifting all other machine part production to our other factories will help us to attain that larger goal.”
