Which of the following best explains how alcohol affects both judgement and reaction?

• A. Judgment and reaction are unaffected by alcohol
• B. Alcohol speeds up processing but slows reaction
• C. It slows information processing and dulls judgment, reducing decisions and delaying reactions
• D. Alcohol speeds thinking and improves multitasking

Answer: (C)

Alcohol slows brain function, making it harder to process information quickly and to judge situations accurately. When you drink, the brain’s processing speed drops, so hazards aren’t noticed as fast and options aren’t evaluated as carefully. The part of the brain that governs judgment and decision-making is dulled, leading to poorer choices and riskier behavior. At the same time, slower processing also slows the motor pathways that control how quickly you respond, so reactions like braking or steering are delayed and coordination can suffer. This combination—slower thinking and impaired judgment—explains why alcohol reduces both decisions and reaction time.

Other statements don’t fit because they inaccurately describe the effects. Alcohol does affect judgment and reaction, it does not speed up processing, and it does not make thinking faster or multitasking easier.
