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.
A是什么？
only 3 percent of drivers on Maryland highways equipped their vehicles with radar detectors
B是什么？
33 percent of all vehicles ticketed for exceeding the speed limit were equipped with them
A和B合起来，是个现象，还没有任何推理。所以当中不可能存在遗漏的ASSUMPTION。
再开C
drivers who equip their vehicles with radar detectors
这个是结论的条件，就是说：
如果有这样的司机，那么。。。
D（are more likely to exceed the speed limit regularly than are drivers who do not. ）
更容易会犯超速的错误。
好，A，B中没有遗漏，那么B，C中有没有？
C是个现象，所以也没有。
那么唯一可能有遗漏的地方就是D中，
从B中的TICKETING到D中的MORE LIKELY就是一个突破点。
有些时候很容易认为这是显而易见的嘛。。。
其实不然，你如果换个思路，比如说把LIKELY TO EXCEED SPEEDLIMIT换成LIKELY TO EARN HIGH SALARY（换一个常人不认为是常理的事情），你就会很简单地看见，哦，确实遗漏了一个ASSUMPTION，
