觉得有点奇怪，Drivers who are ticketed for exceeding the speed limit are more likely to exceed the speed limit regularly than the drivers who are not ticketed/。

Tickected ， Equiped with radar detector, exceed speed. 这三个的关系不是特别清楚

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 drivers who do not.

The conclusion drawn above depends on which of the following assumptions?

A Drivers who equip vehicles with radar detectors are less likely to be tickted for exceeding the speed limit than are drivers who do not.

B 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.

C The number of vegicles that were tickted for exceeding the speed limit was greater than the number of vehicles that were equiped with radar detectors.

D Many of the vehicles that were ticketed for exceeding the speed limit were ticketed more than once in the time period covered by the repot.

E Drivers on Maryland highways exceeded the speed limit more often than did drivers on the state highways not covered in the repor.

答案是B，可是我觉得还是不太清楚。
