5.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.
此题如何解,不太懂老师讲的前后桥梁,可否用另一种更容易想的方法告诉我如何做~,非常感激了~

这里面前后逻辑中存在一个gap,这也证明了在考场上推理逻辑过程的考试方法用一次死一次.
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.
最近一个报告指出尽管马里兰高速路只有3趴的司机装了雷达探测器,但是33趴的超速的司机装备了雷达探测器.显然,装备了雷达探测器的司机比没装雷达探测器的司机更经常性的超速.
问以上假设可以归纳出什么来.快速扫一眼发现DE纯粹是胡扯,直接扔了.看看ABC.
A说装雷达探测器的司机比不装雷达探测器的司机有更小的可能超速被罚.
B说因为超速被罚的司机通常而言比那些没有被罚的司机更经常性的超速.
C说超速被罚的车的数量大于装了雷达探测器的车.
可以发现ABC在说完全不同的事情.一个在比较两种被罚的可能性,一个在比较两种超速的可能性,一个在探讨两种车的数量.原文的结论是什么?原文的结论就是在比较两种不同装备的司机超速的可能性,因此AC都可以扔了.选B.
前后桥梁是啥意思小弟不太明白.这里的逻辑gap是：尽管只有3%的车装雷达,但是33%被罚的车都装了雷达（潜台词为3%的车各种多次超速经常性被罚,数量占到了整个被罚车辆数量的33%).因此这些超速被罚的司机比没有被罚的司机更经常性的超速.感觉regularly在这里很关键= =
