Why might you have trouble recalling what happened after drinking alcohol?

• A. It improves short-term memory
• B. It affects your ability to store and retain information
• C. It has no effect on memory
• D. It enhances recall after sleep

Answer: (B)

Alcohol disrupts memory formation by impairing how new information is encoded and then stored for later use. When you’re intoxicated, the brain’s ability to form lasting memories is reduced, especially for events that occur while drinking. The hippocampus, key for creating new memories, doesn’t work as well under the influence, which is why details can be forgotten or lost in blackouts. This is why the best answer is that alcohol affects your ability to store and retain information. The other ideas don’t fit because alcohol does not improve short-term memory, and it does have an impact on memory. It also doesn’t reliably enhance recall after sleep; in fact, it can disrupt sleep and memory consolidation, making recall after sleep less likely to be improved.
