标题: manhattan逻辑题 [打印本页] 作者: annzhang 时间: 2012-4-14 21:53 标题: manhattan逻辑题 Analyst: The pace of technological development brings a constant stream of new devices to the market, and many of them enjoy commercial success. But announcing new technology too soon after the introduction of a successful device can backfire. Once consumers hear about the new device, they may stop buying the one currently on sale. So, if a company wishes to announce the upcoming sale of a new device, it should wait until purchases of the old device have begun to decline.
Which of the following, if true, would best support the analyst's main assertion? A. New technology often becomes less expensive after an initial surge in sales. B. Media outlets, such as television programs and magazines, often report on the planned introduction of new devices while the sales of old devices are still strong. C. Many consumers are unable to determine whether new technology is superior to current technology. D. Surveys have shown that some consumers make only one or two technology purchases per year, whereas others make more frequent purchases. E. Consumers tend to be loyal to technology companies whose products they enjoy using.
OA is B 解释是这样的:The conclusion is that a company should wait until purchases of an old device have begun to decline before announcing a new device. The basis for this claim is that consumers stop buying the old device. We are asked to strengthen the argument.
(A) The typical drop in the price of new technology does not influence whether a company should wait until sales of an old technology begin to decline before introducing a new one.
(B) CORRECT. This choice states that media outlets such as television and magazines often report on the planned introduction of new devices while sales of old devices are still strong. The argument requires that consumers "hear about the new device"; stories in the media provide a means for consumers to do so.
(C) If many consumers are unable to determine the superiority of new technology, then they might be less swayed to wait for a new, recently announced device than otherwise. As a result, this claim may be seen to weaken the analyst's assertion.
(D) The number of technology purchases per year does not directly relate to this argument. The argument is about waiting until the consumer demand declines before announcing a new technology. However frequently consumers typically purchase technology, some will be ready to buy the old device when news of the upcoming device gets out -- and according to the argument, this news will cause some of those consumers to wait.
(E) The passage makes no mention of whether the technologies belong to the same company or different companies.

结论是：因为新产品过早推出会取代老产品的销量--->所以要等到老产品销量下降时推出新品
理由是：Once consumers hear about the new device, they may stop buying the one currently on sale
那我们就加强这个推断
只有B，说媒体一直宣传新产品，那就满足了consumers hear about the new device，所以加强了这个推论的理由~
