Question

The rate of alcohol involvement among drivers involved in fatal collisions was four times higher ___________

Answer 1

The rate of alcohol involvement among drivers involved in fatal collisions was four times higher at night than during the day (b).

Answer 2

The correct answer is b.

The rate of alcohol involvement among drivers involved in fatal collisions was four times higher at night than during the day.

This would be due to the fact that more people drink in the evenings than during the day. People tend to associate drinking alcohol with a night time activity than a day one so there are more intoxicated drivers at night than during the day and more fatal collisions take place.
