Which is a short-term effect of alcohol on the brain and body for teenagers?

• A. Impaired judgement
• B. Improved concentration
• C. Increased energy
• D. Enhanced coordination

Answer: (A)

Alcohol acts as a depressant on the brain, so even in the short term it slows thinking and affects how you judge situations. For teenagers, whose brains are still developing, this slowing hits the areas responsible for decision-making and impulse control, leading to impaired judgement. That means it’s easier to misread risks, make rushed choices, or act without fully considering consequences. The other options don’t fit because alcohol doesn’t sharpen concentration, provide extra energy, or improve coordination; in fact, it tends to dull focus, lower energy (or make you tired), and worsen balance and motor skills.
