Motorcycle-safety courses, offered by a number of organizations, teach motorcydists
important techniques for handling their vehicles and for safely sharing the road with
other road with other road users. If more motorcyclists took these courses, there
would be fewer serious motorcycle accidents. Data show that 92 percent of the
motorcyclists who are involved in a serious motorcycle accident have never taken a
motorcycle-safety course.
In assessing whether the data cited provide support for the position taken about more
motorcyclists’ taking the courses, it would be most useful to determine which of the
following?
A. Whether significantly more than eight percent of motorcyclists have taken a
motorcycle-safety course?
B. Whether it is riskier for a motorcyclist to ride with a passenger behind the rider than
to ride alone?
C. Whether the different organizations that offer motorcycle-safety courses differ in the
content of the courses that they offer?
D. Whether more than 92 percent of serious motorcycle accidents involve collisions
between a motorcycle and another vehicle in motion?
E. Whether variations in the size and potential speed of a motorcycle influence the risk
of a serious accident’s occurring?

这题是评价题，也就是取非能反驳结论，如果少于百分之八的人上了安全课，那必定会有大于百分之九十二的人没上课出事故，所以结论不成立，反之则成立
