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 mistake, for the amount of energy require 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?
Freezer trucks use substantially more energy per mile driven than do any other types of trucks.
Frozen juice can be stored for several years, while not-from-concentrate juice lasts a much shorter time.
Oranges grown in Brazil make up an increasing percentage of the fruit used in not-from-concentrate juice production.
A serving of not-from-concentrate juice takes up to six times more space than a serving of frozen concentrate juice.
Though frozen concentrated juice must be kept at a lower temperature, not-from-concentrate is far more sensitive to small temperature fluctuations.
我还以为freezer是品牌名呢。。
b是无关选项,只要选和卡车有关的。
冷冻车用来运输冷冻的橙汁,能耗比普通的卡车要高,支持了文中的结论:冷冻橘汁消耗的能源比非冷冻橘汁消耗的要多
关注energy
编辑:北美消费者认为喝冷冻浓缩橙汁节能,因为同量的冷冻浓缩橙汁比起非浓缩橙汁需要更少的卡车来运输——但他们错了,因为将橙汁浓缩的过程所花费的能量,远比运输过程中节省的能量来得大。
下面哪一项附加论述最能支持编辑结论?
A. 冷冻车比其他运输车辆每英里要消耗更多能量
B. 冷冻果汁可以储藏数年,而非浓缩果汁的保质期要远远短于此
C. 在非浓缩橙汁产品的原料里,巴西生长的橙子的比例在上升
D. 一份非浓缩橙汁至多占据一份冷冻橙汁的体积
E. 尽管冷冻浓缩橙汁必须低温保存,但是非浓缩橙汁对温度的变化更加敏感
这一题选A。作者意思是让你找出可以支持“冷冻橙汁消耗能量更多”的选项,那么很明显A是。
P.S.这一题一开始我根本没读懂,因为根本没能把喝橙汁和节省能源两个概念联系在一起。难道老美现在喝个橙汁都在纠结哪一个更节能么……那我还觉得B选项也是正确选项呢,因为冷冻果汁储存更耗电……
GMAC有够搞笑。
可是题目并没有说明运送非浓缩就不是冷冻车啊
这个想法稍微有点过度推测。题目是考考生逻辑链:运输卡车数量变少一定会导致能源降低么。只要找到一条理由来break logic chain 即可。不能过度揣测或者从反方向来提供更多没有的推测,毕竟还可以有太多削弱答案的条件。

consumers倾向于frozen,但反驳提出这是错误的,frozen并没有减少能量消耗。
所以要选出与truck transportion相关的、frozen不好的一面
