求助一道OG题,想不明白

171. 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?

(A) 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.

(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.

答案是选B,我选的是C,

结论是主要讲的是drivers who equip their vehicles with radar detectors ,而B选项却只提的是Drivers who are ticketed for exceeding the speed limit,

大家帮忙分析一下啊,谢谢!

假设题：

 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.可以推出在ticket中with radar的人多，

 drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly than are drivers who do not.speedin中with radar的人多

简历联系，ticket & speeding的联系，要保证结论的成立，b

为什么是with radar的人多啊？不是在ticket中只有３３％吗？
