看了N遍还是不懂啊，脑子短路了~~求大牛解答 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 driverswho 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.
I think the core of the solution can be summarized in one sentence: exceeding speed limit once is not equal to exceeding speed limit REGULARLY. the answer fills the gap.
