  Test9 30mins, 16 questions among which 2 are flaw.

                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? 【不钻牛角尖，只求有人告诉我B是怎么对的】

(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.

文中的事实是：装了雷达的车更有可能被（超速）罚款；

      结论是：装了雷达的车更有可能超速

你现在把B放进去看看 就是答案了

我看到的有点晚，不知你是否已经会了。

就是需要建立连接：证据里边是说因超速而罚款，结论说超速，两个是有区别的，需要假设两者有联系：因超速而罚款的容易超速，就可以了
