Premises: The slow advancement of the technology used in golf balls is a reflection of the demand which manufacturers aim to meet. Only golfers active in competition tournaments are willing to pay the high price necessary to justify the research and development costs needed to generate an innovative golf ball.
Conclusion: Therefore, the technology that manufacturers pursue is limited to that which is deemed permissible for competition go tournaments.
Hope it helps.

This question seems to be a rewording of the below official question:
The technological conservatism of bicycle manufacturers is a reflection of the kinds of demand they are trying to meet. The only cyclist 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.
Which of following is an assumption made in drawing the conclusion above?
a) The market for cheap, traditional bicycle can not 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 purpose of competition.
d) The technology conservatism of bicycle manufacturers results primarily from their desire to manufacturer 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.
