103. The technological conservatism of bicycle manufacturers is a reflection of the kinds of demand they are trying to meet. The only cyclists seriously interested in innovation and willing to pay for it are bicycle racers. Therefore, innovation in bicycle technology is limited by what authorities will accept as standard for purpose of competition in bicycle races. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 看不懂这部分的意思以及解释 Which of the following is an assumption made in drawing the conclusion above? (A) The market for cheap, traditional bicycles cannot expand unless the market for high-performance competition bicycles expands. (B) High-performance bicycles are likely to be improved more as a result of technological innovations developed in small workshops than as a result of technological innovations developed in major manufacturing concerns. (C) Bicycle racers do not generate a strong demand for innovations that fall outside what is officially recognized as standard for purposes of competition. (D) The technological conservatism of bicycle manufacturers results primarily from their desire to manufacture a product that can be sold without being altered to suit different national markets. (E) The authorities who set standards for high-performance bicycle racing do not keep informed about innovative bicycle design. 解释 If racers, the only cyclists interested in innovation, created a strong demand for innovations for purposes other than official competition, then the conclusion would not follow. Therefore choice C-which asserts that racers generate no such demand-is assumed and is the best answer. 不明白这里innovations for purposes 跟 official competition 是指什么？ 谢谢指点！
