A recent report determined that although only three percent of drivers on Maryland highways equipped their vehicles with radar detectors, thirty-three 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 drivers who do not.
The conclusion drawn above depends on which of the following assumptions?
Drivers who equip their vehicles with radar detectors are less likely to be ticketed for exceeding the speed limit than are drivers who do not.
Drivers who are ticketed for exceeding the speed limit are more likely to exceed the speed limit regularly than are drivers who are not ticketed.
The number of vehicles that were ticketed for exceeding the speed limit was greater than the number of vehicles that were equipped with radar detectors.
Many of the vehicles that were ticketed for exceeding the speed limit were ticketed more than once in the time period covered by the report.
Drivers on Maryland highways exceeded the speed limit more often than did drivers on other state highways not covered in the report.
近来的报告确定尽管在Maryland高速只有3%的司机给车装了雷达探测器，所有因超速领罚单的车中33%装了雷达探测器。很明显，给车装探测器的司机更可能经常性超速。
假设题，属增强题范畴
逻辑链：从文中3%和33%的关系---》装探测器的司机更可能领到超速罚单
而文中结论是装探测器的司机更可能经常性超速
所以需要有超速与领超速罚单之间建立关系
A 装rd的司机比不装的司机更少可能因超速领罚单；违背题干事实，排
B 因超速领罚单的司机比没领罚单的司机更可能经常性超速；搭桥增强，符合逻辑链，正确
C 超速领罚单的汽车数比装探测器的车数更多；无关
D 超速领罚单的车中很多领了不止一次罚单；无关
E 超速司机在Maryland比报告外的其他地方更普遍；无关比较。
