标题: 请教大神一个OG逻辑问题
下面这道题是OG上的原题。。。看了解释我还是搞不懂,麻烦哪位大神好心解释一下吧!谢!

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.
(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.
