The ice on the front windshield of the car had formed when moisture condensed during the night. The ice melted quickly after the car was warmed up the next morning because the defrosting vent, which blows only on the front windshield, was turned on full force. Which of the following, if true, most seriously jeopardizes the validity of the explanation for the speed with which the ice melted?
选项
A、The side windows had no ice condensation on them.
B、Even though no attempt was made to defrost the back window, the ice there melted at the same rate as did the ice on the front windshield.
C、The speed at which ice on a window melts increases as the temperature of the air blown on the window increases.
D、The warm air from the defrosting vent for the front windshield cools rapidly as it dissipates throughout the rest of the car.
E、The defrosting vent operates efficiently even when the heater, which blows warm air toward the feet or faces of the driver and passengers, is on.
答案
B
解析
挡风玻璃上的冰融化的速度取决于从除霜口全力吹向前挡风玻璃的空气。如果如(B)所说,没有采取措施对后窗进行解冻,而后窗的冰同前挡风玻璃上的冰融化得一样快,那么就削弱了该解释,因此,(B)是正确答案。在没有其他信息的条件下,(A)中所提到的在边窗上没有冰的凝结同该解释的有效性无关;选项(C)可以支持该解释,因为从解冻风口吹出的空气是热的;(D)和(E)都不能提出一个理由去怀疑是从风口吹出的空气导致了冰的融化,因此都没有威胁到该解释的有效性 从这个例子我们可以看出,五个选项中只有(B)可以实现问题目的,而其他四个选项都不可能实现问题的目的,即只有一个选项是正确的。
