Which of the following is a common effect of alcohol on the body?

One of the common effects of alcohol on the body is slurred speech. This occurs because alcohol is a central nervous system depressant, which impairs the functioning of the brain and nervous system. As a result, coordination, balance, and the ability to articulate words can be significantly affected. When someone consumes alcohol, especially in larger quantities, they may struggle to form words or speak clearly, leading to slurred speech. This is a familiar warning sign of alcohol intoxication, often seen in social situations where drinking occurs.

Enhanced memory and increased judgment are not effects associated with alcohol consumption; in fact, alcohol typically impairs cognitive functions and can lead to memory blackouts or poor decision-making. Similarly, alcohol does not improve motor skills; rather, it hampers coordination and reaction time, making tasks that require fine motor control more difficult.
