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.（B）

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

那位解释一下， 我有点晕了。。谢谢

前提：只有3%的车子装了雷达，而被开发单的车子中有33%是装了雷达的。

结论：装了雷达的车子比没有装的要容易超速。

架桥：前提讲了装雷达，被开罚单的关系。结论是讲雷达和超速的关系。需要在被开罚单和超速之间架桥。B就是被开罚单的人，更容易超速。

我一直架桥的题目做不好，发现短时间内很难对逻辑关系有一个很清晰的想法的，架桥题目一般取非容易想明白逻辑关系。如果取非后，还是觉得中间的逻辑关系绕，那就只能从前提和结论中找到gap，把这个gap联系起来就好了。

探讨探讨！

非常感谢了！～！[em08]
