Critical Reasoning

Interesting CR question here. OA to come...

Studies have shown that a large percentage of car accidents are caused by aggressive driving. To help reduce the number of accidents and to promote traffic safety in general, insurance companies have begun to issue discounts to drivers who take defensive driving courses. Research shows that people who practice defensive driving are considerably less likely to get into a car accident. Therefore, the insurance company's plan should help reduce the number of accidents.

Assuming the statements above are true, which of the following can be inferred from them?

A. The majority of accidents are caused by drivers who possess insurance.
B. People who manage to consistently avoid car accidents are likely practicing defensive driving.
C. Young males and other demographics known for disproportionately being involved in car accidents are less likely to practice defensive driving than other demographics.
D. An individual who does not practice defensive driving is always more likely to get into a car accident than an individual who does practice defensive driving.
E. Discounts are the most effective way for insurance companies to promote defensive driving.

Between A and E,
E does not guarantee if the drivers already have insurance. So providing them discounts doesn't affect the cause much.
'A' confirms that if the majority of accidents are caused by the drivers who already have insurance, then they might get attracted to the discounts offered by the insurance companies and take defensive driving course. This might well reduce the number of accidents on road.

IMO C

The argument: If practicing defensive driving (X), less involve in car accident (Y)
Conclusion: The insurance company's plan should help reduce the number of accidents.

A and E are eliminated. Out of scope. How we can assure that most of car accident are caused by driver who possess the insurance. In choice E, it is too extreme.

Choice B means that If Y, then X. So, wrong
Choice D means that If not X, then not Y. Also, wrong

Only choice C is the correct answer. Tricky one, but we can simplify it by converse into this: If not Y, then not X.

Choice C is the correct answer.
