8.6 Critical Reasoning Answer Explanations

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.（KEY）

(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.

Premise:
1) Innovation in bike is limited by consumer demand.
2) The only cyclists seriously interested in innovation and willing to pay for it are bicycle racers.

Conclusion:
Innovation in bicycle technology is limited by what authorities will accept as standard for purposes of competition in bicycle races.

Logic chains:
1) Innovation in bike --> limited by consumer demand (A --> B)
2) Consumers who demand and pay for innovations --> bike racers (B--> C)
3) Innovation in bike --> limited by standard set by authorities for bike races (A --> D)

If you connect the dots, the assumption has to be C --> D, which is "Bike racers --> standard set by authorities for bike races."

Now check all the answer choices for the one that is the closest to C --> D.

C) Bicycle racers do not generate a strong demand for innovations that fall outside what is officially recognized as standard for purposes of competition.

C) fits the bill.
