The Scorpio Miser with its special high-efficiency engine costs more to buy than the standard Scorpio sports car. At current fuel prices , a buyer choosing the Miser would have to drive it 60,000 miles to make up the difference in purchase price through savings on fuel .It follows that ,if fuel prices fell ,it would take fewer miles to reach the break-even point. Which one of the following arguments contains an error of reasoning similar to that in the argument above? (A) The true annual rate of earnings on an interest-bearing account is the annual rate of interest less the annual rate of inflation drops, the rate of interest can be reduced by an equal amount without there being a change in the true rate of earnings. (B) For retail food stores ,the Polar freezer, unlike the Arctic freezer, provides a consistent temperature that allows the store to carry premium frozen foods. Thus ,if electricity rates fell ,a lower volume of premium-food sales could justify choosing the Polar freezer . (C) With the Roadmaker ,a crew can repave a mile of decayed road in less time than with the competing model, which is ,however, much less expensive. Reduced staffing levels made possible by the Roadmaker eventually compensate for its higher price .Therefore, the Roadmaker is especially advantageous where average wages are low. (D) The improve strain the Northland apple tree bears fruit younger and lives longer than the standard strain .The standard strain .The standard strain does grow larger at maturity ,but to allow for this ,standard trees must be spaced farther apart. Therefore , new plantings should all be of the improved strain. (E) Stocks pay dividends ,which vary from year to year depending on profits made. Bonds pay interest ,which remains constant from year to year . Therefore ,since the interest earned on bonds does not decrease when economic conditions decline , investors decline , investors interested in a reliable income should choose bonds. 这个题目的error是什么,是不是题目总的fewer有问题,说反了, 碰到这种题目我总是做错,不知道到底怎么比较,能不能说一下正确的答案c如何是和题目的error一致的 25. Situation: In the island nation of Bezun ,the government taxes gasoline heavily in order to induce people not to drive . It uses the revenue from the gasoline tax to subsidize electricity in order to reduce prices charged for electricity. Analysis: The greater the success achieved in meeting the first of these objectives, the less will be the success achieved in meeting the second . The analysis provided for the situation above would be most appropriate in which one of the following situations? (A) A library charges a late fee in order to induce borrowers to return books promptly. The library uses revenue from the late fee to send reminders to tardy borrowers on order to reduce the incidence of overdue books . (B) A mail-order store imposes a stiff surcharge for overnight delivery in order to limit use of this option. The store uses revenue from the surcharge to pay the extra expenses it incurs for providing the overnight delivery service. (C) The park management charges an admission fee so that a park's users will contribute to the park's upkeep. In order to keep admission fees low ,the management does mot finance any new projects from them. (D) A restaurant adds a service charge in order to spare customers the trouble of individual tips. The service charge is then shared among the restaurant's workers in order to augment their low hourly wages. (E) The highway administration charges a toll for crossing a bridge in order to get motorists to use other routes .It uses the revenue from that toll to generate a reserve fund in order to be able one day to build a new bridge. 这一题和上题类似,都是不知道如何相似的,答案是E,我一个一个地看了半天,不理解! 请高手指教一下有没有对付这些题目的高招,我都是一个一个地看,费时很多还是不知道选哪一个, 不是觉得都不对,就是觉得对了太多,郁闷!
