答案 (A) 基本上就是 GMAT CR 常考的无关选项 当题目提到 Sales or Revenue 而答案有提到 cost 基本上都无关 虽说 GMAT 不考专业的商业知识 但 GMAT 认定这是大家必须知道的基本概念 来看以下例题 Many large department stores in Montalia now provide shopping carts for their customers. Since customers using shopping carts tend to buy more than those without shopping carts, most of these stores are experiencing strong sales growth, while most other department stores are not. Therefore, in order to boost sales, managers of Jerrod's, Montalia's premier department store, are planning to purchase shopping carts and make them available to the store's customers next month. Which of the following, if true, casts most doubt whether the managers' plan, if implemented, will achieve its goal? A. Since most customers associate shopping carts with low-quality discount stores, Jerrod's high-quality image would likely suffer if shopping carts were introduced. B. Because the unemployment rate has declined to very low levels, Jerrod's now has to pay significantly higher wages in order to retain its staff. C. A number of department stores that did not make shopping carts available to their customers have had to close recently due to falling profits. D. Shopping carts are not very expensive, but they generally need to be replaced every few years. E. Stores that make shopping carts available to their customers usually have to hire people to retrieve the carts from parking areas. 此 weaken 题的因果关系: shopping carts --> boost sales 而答案选项 B (员工薪水上升), D(推车替换), E (雇用员工) 皆为讨论成本的议题 而答案 C 很明显是 support 需要补充推车的选项 只有答案 A --> 推车会破坏 Jerrod's 的形象 所以，题目如果讨论 sales/revenue，讨论 cost 的多半是无关选项 就如本题原题的 spending 一样 ※ 引述《isss (Hua)》之铭言： : Denoma, a major consumer-electronics maker, had a sizable decline in sales : revenue for its most recent fiscal year. This result appears surprising, : because electronics retailers report that although their overall sales were : considerably lower than in the previous year, their sales revenue from : Denoma models actually grew, largely thanks to some innovative and popular : models that Denoma introduced. : Which of the following, if true, does most to explain the apparently : surprising result? : A. Because of the need to educate the public about its new models’ : capabilities, Denoma’s advertising spending was higher than normal : over the period. : B. For the period at issue, Denoma’s major competitors reported declines : in revenue that were, in percentage terms, greater than Denoma’s. : C. A significant proportion of Denoma’s revenue comes from making : components for other consumer-electronics manufacturers. : D. Unlike some of its major competitors, Denoma has no lines of business : outside consumer electronics to provide revenue when retail sales of : consumer electronics are weak. : E. During the period, consumer-electronics retailers sold remaining units : of Denoma’s superseded models at prices that were deeply discounted : from those models’ original prices. : OA:C : 逻辑链如下： : sales revenue from Denoma models actually grew : (some innovative and popular models) : -->Denoma had a sizable decline in sales revenue (非预期结果) : 想请教一下A选项为何是错误的？ : 若advertising spending 上升 也会导致revenue 相对减少 -- Donz 2015 7~8月全科机经班: http://goo.gl/VwO4yJ Donz + Keewee 速成实力暑假班: http://ndxica.pixnet.net/blog/post/40937209 Donz GMAT FB: https://www.facebook.com/groups/DonzGMAT --
