To support the claim that the United States automobile industry's reluctance to pursue fuel-efficient technologies could threaten its future, we need to identify an option that demonstrates a potential negative impact on the industry's competitiveness or market position due to this reluctance.
Let's evaluate each option:
(A) A prototype fuel-efficient vehicle, built five years ago, achieves a very high 81 miles per gallon on the highway and 63 in the city, but its materials are relatively costly.
This option doesn't directly address the future threat to the US automobile industry but rather provides a historical example and a cost concern.
(B) Small cars sold by manufacturers in the United States are more fuel efficient now than before the sudden jump in oil prices in 1973.
This option shows improvement in fuel efficiency but doesn't explain how reluctance to develop new technologies could threaten the industry's future.
(C) Automakers elsewhere in the world have slowed the introduction of fuel-efficient technologies but have pressed ahead with research and development of them in preparation for a predicted rise in world oil prices.
This option shows that while US automakers are not pursuing new technologies, their competitors are continuing to develop them. This could lead to US automakers being at a disadvantage when oil prices rise, supporting the claim about the industry's future threat.
(D) There are many technological opportunities for reducing the waste of energy in cars and light trucks through weight, aerodynamic drag, and braking friction.
This option indicates that there are opportunities for improvement but doesn't directly address the competitive threat to the US industry.
(E) The promotion of mass transit over automobiles as an alternative mode of transportation has encountered consumer resistance that is due in part to the failure of mass transit to accommodate the wide dispersal of points of origin and destinations for trips.
This option is about consumer resistance to mass transit and doesn't directly relate to the future threat to the automobile industry.
Correct Answer: (C)
(C) provides the most support for the claim by highlighting that global competitors are continuing to develop fuel-efficient technologies, potentially placing US automakers at a future competitive disadvantage.
