What is a common effect of alcohol consumption based on dosage?

A common effect of alcohol consumption based on dosage is diminished ability to react properly. As blood alcohol concentration (BAC) increases, individuals typically experience a decline in their motor skills and cognitive functions. This impairment affects reaction times, coordination, and judgment, making it difficult to perform tasks that require quick thinking and physical capabilities, such as driving or operating machinery.

In contrast, other options suggest effects that are not aligned with alcohol's impact on the brain and body. For instance, increased ability to multitask, better decision-making skills, and enhanced cognitive function are generally associated with levels of attention and performance that alcohol consumption negatively influences. As alcohol affects neurotransmitters and overall brain function, the sober mind is much better equipped for tasks requiring critical thinking and complex coordination.
