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

我个人认为，选C也对，因为被罚罚金的人数多与安装雷达探测器的人数，然后在被罚人数中安装雷达的人比例高，不是可以说明这个问题吗，不解不解

这个题目问的是assumption喔，不是weaken哦，C的话可以是weaken这个conclusion的一点
这道题关键是发现ticketed for exceeding the speed limit 和exceed the speed regularly之间的关系~中间有个gap在
而B fulfill 了这个gap
