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?

ADrivers who equip their vehicles with radar detectors are less likely to be ticketed for exceeding the speed limit than are drivers who do not.
BDrivers who are ticketed for exceeding the speed limit are more likely to exceed the speed limit regularly than are drivers who are not ticketed.
CThe number of vehicles that were ticketed for exceeding the speed limit was greater than the number of vehicles that were equipped with radar detectors.
DMany of the vehicles that were ticketed for exceeding the speed limit were ticketed more than once in the time period covered by the report.
EDrivers on Maryland highways exceeded the speed limit more often than did drivers on other state highways not covered in the report.

正确答案: B

我是这样分析的：
题目中的33 percent of all vehicles ticketed for exceeding the speed limit were equipped with them.和B选项中的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.这两部分是相互对应的，而与结论中的drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly than are drivers who do not.也是对应的。填补了GAP：谁are more likely to exceed the speed limit regularly.

我自己举了一个类似的例子，方便理解：
3%的飞机有双涡轮发动机。在因耗油量大而失去动力的飞机中，有33%的飞机装有双涡轮发动机。因此，装有双涡轮发动机的飞机比没有装的飞机更容易失去动力。
Q：假设
A：因为耗油量大而失去动力的飞机比没有耗油量大的飞机更加容易失去动力。
注意：假设中的“因为耗油量大而失去动力的飞机”其实就是指了原文中的装有双涡轮发动机的飞机，然后运用到结论里面！

我觉得这个分析是我看到的最清晰明了的~
