A recent report determined that although only three percent of drivers on Maryland
highways equipped their vehicles with radar detectors, thirty-three 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.

答案是A

这道题在OG上也出现过，但是一直没有想通。
大家可以帮忙解释一下这道题吗？

答案應該是B吧？！SUPPORTER ASSUMPTION的原理.CLEARLY之前應該有一個LINK在中間鏈接之前一句及CONCLUSION的。打個比方，VEHICLES TICKETED FOR EXCEEDING THE SPEED... WITH THEM.就系鏈接物，到CONCLUSION時，該物消失了只得WITH RADAR DETECTORS... THE SPEED LIMIT...，所以本應有個連帶關係解釋，從而得出最後的CONCLUSION。
