弱弱的求解一道逻辑题

OG12th    78题目

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 equiped 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 folowing 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.

CThe number of vehicles that were ticketed for exceeding the speed limit were ticketed more than once in the time period convered by the report

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 hghways exceeded the speed limit more often than did drivers on other state highways not covered in the report.

前提:33% 被ticket的车配有雷达
假设:被ticket的人本身就更容易超速
结论: 雷达车更容易超速.
我不知道怎么说, 只能这样写!!
被ticket 的人爱超速, 然后,
33%被ticket 都是雷达, 所以雷达爱超速.

这题怎么了  这篇文章你要明白说了开罚单和超速 这两件事情  作者的结论是说装雷达的比不装的更有可能超速  他的reasoning是33%超速而开罚单(tickets)都装了雷达   但是这两者并不能联系起来! B说那些超速而开罚单(tickets)比超速没有开罚单的更容易超速 这就说明了问题样本具有代表性!希望对你有帮助
