单选题 9.Editorial: Consumers in North America think that by drinking frozen concentrated orange juice, they are saving energy, because it takes fewer truckloads to transport it than it takes to transport an equivalent amount of not-from-concentrate juice. But they are mistaken, for the amount of energy required to concentrate the juice is far greater than the energy difference in the juices' transport.
Which of the following, if true, would provide the greatest additional support for the editorial's conclusion?

A、 Freezer trucks use substantially more energy per mile driven than do any other types of trucks.
B、 Frozen juice can be stored for several years, while not-from-concentrate juice lasts a much shorter time.
C、 Oranges grown in Brazil make up an increasing percentage of the fruit used in not-from-concentrate juice production.
D、 A serving of not-from-concentrate juice takes up to six times more space than a serving of frozen concentrated juice.
E、 Though frozen concentrated juice must be kept at a lower temperature, not-from-concentrate juice is far more sensitive to small temperature fluctuations.

【正确答案】 A

【答案解析】Argument Evaluation
Situation North American consumers think that drinking frozen concentrated orange juice saves energy because the concentrated juice can be transported in fewer truckloads than an equivalent amount of not-from-concentrate juice. But more energy is required to concentrate the juice than is saved by this reduction in the number of truckloads used for transportation.
Reasoning What additional evidence would most help to support the conclusion that drinking frozen concentrated orange juice rather than not-from-concentrate juice does not save energy? Factors other than the concentration process and the number of truckloads used for transportation may also affect the amounts of energy used to provide the two types of juice. Evidence of any such factor that increases the amount of energy needed to provide frozen concentrated juice more than it increases the amount needed to provide the same amount of not-from-concentrate juice would help to support the editorial's conclusion.
A Correct. This suggests that it takes much more energy per truckload to transport frozen concentrated juice than to transport not-from-concentrate juice, which is not frozen.
B If anything, this suggests that a higher proportion of not-from-concentrate juice goes bad and is discarded rather than being drunk. This waste would increase the amount of energy used to provide each glass of not-from-concentrate juice that is drunk.
C Since Brazil is far from North America, this suggests that the average amount of energy used to transport each serving of not-from-concentrate juice may be increasing.
D Since both types of juice must be kept cold until ready to drink, this suggests that a much larger amount of space must be refrigerated to provide each serving of not-from-concentrate juice. That may mean that more energy needs to be used to keep each serving of not-from-concentrate juice cold.
E It may take extra energy to keep the temperature of not-from-concentrate juice more constant. If it does, that would increase the amount of energy used to provide each serving of not-from-concentrate juice.
The correct answer is A.
