How does alcohol impair judgement?

• A. It speeds up decision making
• B. It improves concentration
• C. It affects areas of the brain that control judgement
• D. It has no effect on concentration

Answer: (C)

Alcohol disrupts the brain areas that control judgement. When you drink, it acts as a depressant on the central nervous system and slows communication between brain regions, especially the frontal lobes that handle decision-making, impulse control, and risk assessment. With those areas not working as well, you’re less able to weigh consequences, monitor hazards, and regulate impulses, which leads to poorer judgement. This also explains why concentration tends to drop after drinking, making it harder to focus on details and stay aware of your surroundings. So, the idea that alcohol affects the parts of the brain that govern judgement is the best description of how it impairs decision-making.
