D
Insurance agent: Cars are no safer than motorcycles; that is, when driven at high speeds, cars are not involved in more fatal crashes than are motorcycles. We conducted a survey about car Y and found that highspeed crashes involving car Y resulted in 40% of the fatalities in 2005 while motorcycles were involved in only 35% of the fatalities in 2005. Each of the following describes a potential flaw in the insurance agent's reasoning EXCEPT:
A: A conclusion is drawn about cars in general on the basis of a study focusing on car Y.
B: The survey being used to support the conclusion failed to take into account the significance of the total number of motorcycles that are driven compared to the numbers of car Y that are driven.
C: The safety of a vehicle might depend on other factors besides how often that vehicle is involved in high-speed crashes resulting in fatalities.
D: The insurance agent based his conclusion on the total number of car crashes, not just on those resulting in fatalities.
