Q78.
A recent report determined that although only 3 percent of drivers on Maryland highways equipment 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 detecters are more likely to exceed the speed limit regularly than are drivers who do not.
the conclusion drawn above depends on which of the assumotions?
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 likely to exceed the speed limit reguarly 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 vehicels that were ticketed for exceeding the speed limit wre located more than once in the time period covered by the report.
E Drivers on Maryland highways exceeded the speed limit more often than diDd drivers on other state highways not covered in the report
这个题我开始想不明白，也看了很久别人的解释，最后是被有位同学的“regularly”给开了窍
也说说我自己开窍的想法。简言之：
既然highway“高速情况”不能代表regularly“一般情况”，如何让“高速情况”能代表“一般情况”？就是我们找assumption的
依据。那么就是B选项的挨罚的人一般比不挨罚的人更容易超速（真理，适用于高速，也适用于一般）。
我觉得，跟装不装“雷达”一点关系都没有，装什么都成。你把“装雷达的车”换成“红色的车”神马的，也是一样。这样的话，选项中跟雷达有关的ABC首先就能排除了。

这个帖子也有讨论

谢谢3.4楼的解释，我一直觉得regularly多少有点与题目相关（如上面帖子所讨论的），莫不是被误导了 囧oz~
