Modern manufacturers, who need reliable sources ofmaterials and technologically advanced components to operate profitably, face an increasinglydifficult choice between owning the producers of these items (a practice known as backwardintegration) and buying from independent producers. Manufacturers who integrate may reapshort-term rewards, but they often restrict their future capacity for innovative product development. Backward integration removes the need for some purchasingand marketing functions, centralizers overhead, and permits manufacturers to eliminateduplicated efforts in research and development. Where components are commodities (ferrous metals orpetroleum, for example), backward integration almost certainly boosts profits.Nevertheless, because product innovation means adopting the most technologically advanced andcost-effective ways of making components, backward integration may entail a serious risk for atechnologically active company-for example, a producer of sophisticated consumer electronics. A company that decides to make rather than buy importantparts can lock itself into an outdated technology. Independent suppliers may be unwilling toshare innovations with assemblers with whom they are competing. Moreover, when an assembler setsout to master the technology of producing advanced components, the resulting demands onits resources may compromise its ability to assemble these components successfully intoend products. Long-term contracts with suppliers can achieve many of the same cost benefits asbackward integration without compromising a company’s ability to innovate. However, moving away from backward integration is not acomplete solution either. Developing innovative technologies requires independent suppliers ofcomponents to invest huge sums in research and development. The resulting low profitmargins on the sale of components threaten the long-term financial stability of these firms. Because theability of end-product assemblers to respond to market opportunities depends heavily onsuppliers of components, assemblers are often forced to integrate by purchasing the suppliers ofcomponents just to keep their suppliers in business.
259. Which of the following best describes the way thelast paragraph functions in the context of the passage? (A) The last in a series of arguments supporting the centralargument of the passage is presented. (B) A viewpoint is presented which qualifies one presentedearlier in the passage. (C) Evidence is presented in support of the argumentdeveloped in the preceding paragraph. (D) Questions arising from the earlier discussion areidentified as points of departure for further study of the topic. (B) (E) A specific example is presented to illustrate the mainelements of argument presented in the earlier paragraphs.
OG给出B选项是正确答案,而且说明At the end of the third paragraph, the authorindicates that assemblers benefit from contracting with,rather than owning, independent suppliers. In the last paragraph, however, the author indicates thatcontracting with independent suppliers can itself present problems. Thus the last paragraphqualifies the viewpoint presented at the end of the third paragraph
怎么看qualify都没觉得有表示转折的意思啊,考古了下也没有相关的解释。而且qualify这个词在OG其他阅读的正确选项里也出现过,
有人总结过这个是怎么说吗,谢谢了
