[問題]OG(11th) Q81

[GuDon]

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.
(A)Drivers on Maryland highways exceeded the speed limit more often than did drivers on other state highways not covered in the report.

Ans:B

請問可否有大大幫忙我解釋一下這題
雖然我看了OG上的解釋可是真的還是不大懂
這題的思路到底要怎麼想阿~~
而且為什麼要提到regular habits of drivers
是不是33% of all vehicles ticketed for exceeding the speed limit只是個無相關的數據
想這題想超九哀又真煩

感謝大大解題
