28. 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 purposes of competition in bicycle races.
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
答案是C，看了解释，还不是很明白，有哪位大侠能解释一下思路吗，谢谢 |
