大全13-10

Today’s low gasoline prices make consumers willing to indulge their preference for larger cars, which consume greater amounts of gasoline as fuel. So United States automakers are unwilling to pursue the development of new fuel-efficient technologies aggressively. The particular reluctance of the United States automobile industry to do so, however, could threaten the industry’s future.

Which of the following, if true, would provide the most support for the claim above about the future of the United States automobile industry?

(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.

(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.

(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.

(D) There are many technological opportunities for reducing the waste of energy in cars and light trucks through weight, aerodynamic drag, and braking friction.C

(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 trip

答案是C,请教一下NN

题目的意思是因为油价的下跌,美国汽车生产商不再追求高效能的技术,但是这是对汽车产业未来不利的

C的意思是,表面上看,别的国家的生产商也没有生产什么高效能的技术的汽车,但是他们并没有停止研究,一旦,油价上涨,他们可以立即投入生产.而美国的生产商却没有未雨绸缪,不能快速应对环境的变化.

A is good but not enough since we do not know the cost of new cars and old ones.

B is on the opposite and has less relation with the points

C, the best answer, which allude the predict rise in the price of oil, the condition will hurt the automaker. 

D makes no sence since the customers need big cars, it's unnecessary to make the fule-effecient cars only due to the higher technology development.

E comparsion between mass transport and automobiles besides the point of argument.
