Increased alcohol tolerance affects a person by:
d. Lessening the effect of alcohol on the central nervous system
Explanation:
1. Alcohol tolerance refers to the reduced sensitivity to the effects of alcohol over time.
2. When a person develops increased alcohol tolerance, they may require higher amounts of alcohol to feel its effects.
3. This increased tolerance can lead to a situation where the person feels less intoxicated or impaired by the same amount of alcohol that would affect others more significantly.
4. Ultimately, increased alcohol tolerance can result in the diminished impact of alcohol on the central nervous system, making it seem like the person is less affected by the alcohol they consume.
