Which behaviour is a common indication of alcohol influence?

Slurred speech is a well-known indication of alcohol influence, as it results from the depressant effects of alcohol on the central nervous system. When an individual consumes alcohol, it can impair the functions of the brain responsible for coordinating speech, leading to a slower, more incoherent manner of speaking. This speech pattern is often a clear and observable sign that someone may be under the influence of alcohol, making it easy to identify in various situations.

In contrast, excessive control of body movements and exhibiting fine motor skills would suggest that the individual is functioning normally or is even sober, as alcohol typically diminishes control rather than enhances it. High verbal clarity similarly indicates coherent thought processes and control over speech, which would not typically be present in someone who is intoxicated.
