[求助]请教一题

81. 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 their vehicles with radar detectors are is likely to be ticketed 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 vehicles that were ticketed for exceeding the speed limit was greater than the number of vehicles that were equipped 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 report.

(E)       Drivers on Maryland highways exceeded the speed limit more often than did drivers on other state highways not covered in the report.

答案是B

(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.

（than are drivers） who are not ticketed.

括号里是什么意思？

 -----------------------------------

“ticketed for exceeding the speed limit” 和"exceed the speed limit regularly

由于超速被罚款——经常超速

B：超速被罚款比没被罚款的更可能经常超速

所以你觉得B提供了联系？

但题目的重心难道不是在雷达吗？装了雷达的比没装的更可能经常超速，这个结论是怎么得出来的
