OG 11-110: 110. "Fast cycle time" is a strategy of designing a manufacturing organization to eliminate bottlenecks and delays in production. Not only does it speed up production, but it also ensures quality. The reason is that the bottlenecks and delays cannot be eliminated unless all work is done right the first time. The claim about quality made above rests on a questionable presupposition that____ (A) any flaw in work on a product would cause a bottleneck or delay and so would be prevented from occurring on a "fast cycle" production line (答案) (B) the strategy of "fast cycle time" would require fundamental rethinking of product design (C) the primary goal of the organization is to produce a product of unexcelled quality, rather than to generate profits for stockholders (D) "fast cycle time" could be achieved by shaving time off each of the component processes in a production cycle (E) "fast cycle time" is a concept in business strategy that has not yet been put into practice in a factory 文中最后一句提到,"推理是,不能消除瓶颈(和延迟)除非所有的工作一开始就正确"由于是not A unless B的句式,这句话的意思也就是说"消除瓶颈-->一开始就正确",也就等于"一开始错误,那么就有瓶颈".这样的话就与A选项完全相符了,那我就不明白了,题干要的是假设,可A是从文章的最后一句话里直接推理出来的,怎么就对文章构成了假设呢?? 多谢!!!
