While motorcycles with larger, more powerful engines generally

While motorcycles with larger, more powerful engines generally accelerate faster and achieve higher speeds than can be achieved by motorcycles that have smaller engines, the majority of motorcycle crashes involve motorcycles with smaller engines. Therefore, to improve the safety of people who ride motorcycles, we should encourage them to ride motorcycles with larger, more powerful engines.

Which of the following if true most seriously weakens the argument above?

A. More experienced and knowledgeable riders are more likely to ride motorcycles that have larger engines than motorcycles that have smaller engines.

B. Motorcycles that have smaller engines tend to be lighter and therefore easier to maneuver at low speeds than motorcycles with larger engines.

C. The average speed at which motorcycles were traveling just prior to crashes is relatively low, approximately 30 miles per hour.

D. Approximately 75 percent of crashes involving motorcycles also involve another vehicle, most often a passenger automobile.

E. Passing on two lane highways can generally be done more quickly, and thus more safely, on a motorcycle with a larger engine than on one with a smaller engine.
