The use of radar detectors in commercial vehicles was banned because commercial truck and bus drivers were using these devices to drive faster than the posted speed limit without fear of arrest. Since drivers of noncommercial vehicles also use radar detectors and since speeding decreases safety for any vehicle, use of radar detectors should also be banned in noncommercial vehicles to increase safety.
Which of the following, if true, most strongly supports the argument above?
The average noncommercial-vehicle driver is involved in less long-distance driving than is the average commercial-vehicle driver.
In many places airplanes or helicopters are used rather than radar to locate vehicles traveling faster than the posted speed limit.
The ban on radar detectors in commercial vehicles has been effective in deterring them from speeding.
Traffic accidents involving a truck or bus generally pose a greater threat of injury or death than do other accidents.
Radar detectors are sometimes set off by devices other than the law enforcement devices that the radar detectors were built to detect.
翻译一下答案E：Radar detectors are sometimes set off by devices other than the law enforcement devices that the radar detectors were built to detect.
雷达探测器有时候被其他的设备触发，而不是执法部门的设备触发，虽然雷达探测器就是为了检测这些执法部门的设备而被制造的。（美国的radar detector用来检测执法部门设置在公路上的测速装置，来提醒司机不要超速，以免吃罚单）我之所以错是感觉E看起来意思正确，其实我并没有理解E的意思。C选项正确，因为是通过其他类似措施的例子达到了效果，从而加强了逻辑链。
