A recent study of 10,000 people who were involved in automobile accidents found that a low percentage of those driving large automobiles at the time of their accidents were injured, but a high percentage of those who were driving small automobiles at the time of their accidents were injured. Thus, one is less likely to be injured in an automobile accident if one drives a large car rather than a small car.

Summarize Argument
The author concludes one is less likely to be injured in an accident if they drive a large car rather than a small car. This is based on a study that a higher percentage of people driving small cars were injured in accidents than people driving large cars.

Notable Assumptions
Based on that fact that a higher percentage of people driving small cars were injured in accidents, the author concludes you’re less likely to be injured in an accident if you’re driving a large vehicle. The author therefore assumes that large vehicles don’t get in so many more accidents as to outweigh the relative percentages.

A
Most of the accidents analyzed in the study occurred in areas with very high speed limits.
We need something that differentiates large and small cars. This tells us something was constant during the study.
B
Most people who own small cars also drive large cars on occasion.
The study is about people who got in accidents, not people who left their cars in the garage. We don’t care what people own.
C
Half of the study participants drove medium-sized cars at the time of their accidents.
We’re not comparing with meidum-sized cars. We only car about large and small cars.
D
A large automobile is far more likely to be involved in an accident than is a small automobile.
Let’s say 2 out of 100 people driving small cars got in accidents and both were seriously injured. On the other hand, 20 out of 100 people driving large cars got in accidents and 10 were seriously injured. Those driving large cars were thus more likely to be injured.
E
Only a small percentage of those people involved in an automobile accident are injured as a result.
We care whether small car drivers or large car drivers are more likely to be injured in accidents. This lacks a comparative aspect.
