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?
选项:
A说车里有雷达的司机相比于没装雷达的司机超速罚款的可能性更小,原文说的是更多了。
B说超速而且被开罚单的车更有可能超速,OG的解释是This statement properly identifies the conclusion s necessary assumption about ticketed drivers' being more likely to drive in excess of the speed limit than nonticketed drivers.
直接把结论和结论连接上了,结论说有装测速器的车比较容易超速,装了测速器应该比较不会被开罚单,但是却还是被开,也就是说那些被开罚单的人是真的经常超速.
简单的来说,被开罚单的人(A)= 装测速器的人(B) 而结论是装测速器(B)=爱超速(C),所以前提就是被开罚单的人(A)=爱超速(C)
C说到开罚单的车子数,但是number和题目讨论的是无关的
D和E,应该能很明显的看出来不相关

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.
