标题: GWD15套两道题 [打印本页] 作者: 狂威雪 时间: 2011-6-5 23:06 标题: GWD15套两道题 ------------------------------------------------------------------------------------------------------------ 30. GWD21-Q30: In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number of children injured while sledding was much higher last winter than it was ten years ago. Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?
A. A few children still use traditional wooden sleds. B. Very few children wear any kind of protective gear, such as helmets, while sledding. C. lastic sleds can be used in a much wider variety of snow conditions than wooden sleds can. D. Most sledding injuries occur when a sled collides with a tree, a rock, or, another sled. E. Because the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured. ---------这题答案是C 但是我的思路是由于受伤的人多，原因就是塑料鞋。应该找他因排除，那么D答案就是解释手上人多的他因呀~~很不解 -------------------------------------------------------------------------- 40. GWD21-Q40: A manufacturer of workstations for computer-aided design seeks to increase sales to its most important corporate customers. Its strategy is to publish very low list prices for workstations in order to generate interest among the buyers for those corporations. 一个设计computer-aided工作站的制造商寻找增加销售额为它最重要的合作顾客。这个计划就是为工作站出给低价位为了获得买家的兴趣。 Which of the following, if characteristic of the marketplace, would tend to cause the manufacturer’s strategy to fail?
A. The proposed list prices would seem low to a typical buyer for the manufacturer’s most important corporate customers. B. The capabilities of workstations suitable for given jobs are not significantly different among various manufacturers. C. The manufacturer’s most important corporate customers employ as buyers persons who are very knowledgeable about prices for workstations for customer-aided design. D. Customers differ significantly in the percentage of resources they can devote to computer workstations. E. Buyers for corporations that purchase workstations for computer-aided design receive bonuses for negotiating large discounts from the list price. --------------------------------------------------------------------------------------- 答案是E 不理解题意选了C答案，觉得C答案中包括了题干中的所有元素 请NN指点，谢谢啦作者: Thruth 时间: 2011-6-6 00:09
1. Being asked "Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?" And you are still assuming that "是由于受伤的人多，原因就是塑料鞋。" 抱着预设结论，只能选出相反答案。 ps.sled是雪橇。
It is critical reasoning being tested here, not summarization. I can see no reason why “C答案中包括了题干中的所有元素” indicates correctness.
lastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.
