Quizplus · Accepted Answer

The correct sentence structure is "Alcohol had a significant effect on driving performance." "Affect" is a verb and "effect" is a noun. "Effect" is the correct word to use in this sentence to indicate the outcome of alcohol on driving performance. "Effected" in option B is the incorrect form of the verb, and option D uses the wrong word, "affected," to convey the intended meaning.
