A recent report determined that although only 3 percent of drivers on Maryland highways equipped their vehicles with radar detectors.33% 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. Q: assumptions A: Drivers who are ticketed for exceeding the speed limit are more likely to exceed the speed limit regularly than are driver who are not ticketed. 结论是 drivers with detectors are more likely to exceed… 前提是 ticketed drivers are more likely to exceed… 真的想不通，谁能解释一下。
