?，78. 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 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. B
(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.

问支持结论的假设，结论是装雷达的司机比不装雷达的司机更经常超速，因为原文中说33%被开罚单的人都装了雷达，显然装雷达的人更容易被开罚单（否则应该有3%左右的被开罚单者是装雷达的）
因此assumption应该是被开罚单的更容易经常超速。

本题中被开罚单和经常超速是两个不同的概念，结论是经常超速，而原文能推出的是被开罚单，assumption就需要将两者联系起来。
