标题: OG10-123，如何区分assumption类型和must be ture类型 [打印本页] 作者: amandafly 时间: 2009-11-11 23:38 标题: OG10-123，如何区分assumption类型和must be ture类型 该题LAWYER定义为assumption类型，但是问题里有must be ture，并且是on the basis of the statement above。怎么能快速区分该题目是assumption类型而不是must be ture类型啊？因为只有用assumption的思路才能快速找出答案。请各位赐教~~ 123. Advertisement: Today’s customers expect high quality. Every advance in the quality of manufactured products raises customer expectations. The company that is satisfied with the current quality of its products will soon find that its customers are not. At MegaCorp, meeting or exceeding customer expectations is our goal. Premise: advance in quality->raise customer expectations. Satisfied->customer expectations not met(逆否命题就是meet or exceed customer expectation, not satisfied(advance in quality)) Conclusion: meeting or exceeding customer expectation/ goal Which of the following must be true on the basis of the statements in the advertisement above? (A) MegaCorp’s competitors will succeed in attracting customers only if those competitors adopt MegaCorp’s goal as their own. （comeptitors的情况属于无关） (B) A company that does not correctly anticipate the expectations of its customers is certain to fail in advancing the quality of its products. (好像是第二个条件的否命题) (C) MegaCorp’s goal is possible to meet only if continuing advances in product quality are possible. （only if 是必要条件的指示词meet or exceed customer->continuing advances in product quality） (D) If a company becomes satisfied with the quality of its products, then the quality of its products is sure to decline. （充分必要，错） (E) MegaCorp’s customers are currently satisfied with the quality of its products. （mega的consumer的情况不知道）
