A recent report determined that although only 3 percent of drivers on Maryland highways equipped their vehicles with radar detectors, 33 percent of all vehicles ticketed for exceeding the speed limit were equipped with them. Clearly, drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly than are dirvers who do not.
The conclusin drawn above depends on which of the following assumptions?
A. Driver who equip their vehicles with radar detectors are less likely to be ticketed for exceeding the speed limit than are drivers who do not.
B. Drivers who are tickted for exceeding the speed limit are more likely to exceed the speed limit regularly than are drivers who are not ticketed.
C. The number of vehicles that were ticketed for exceeding the speed limit was greater than the number of vehicles that were equipped with rader detectors.
(累死我了)the ans. is B. 看了答案也不知道为什么. 哪位高人可否指点一下. 谢先! |
