Which statement about memory during a blackout is true?

• A. A blackout means you are awake but cannot remember what happened.
• B. A blackout means you lose consciousness.
• C. A blackout means you remember everything clearly.
• D. A blackout means you were never intoxicated.

Answer: (A)

The key idea is that a blackout is about memory formation, not consciousness. When alcohol intake is very high, the brain’s ability to encode new experiences into long-term memory is impaired, especially in the hippocampus. You can be awake, interact with people, and carry on activities, but those events aren’t stored in memory after the fact. So you may have no recollection of what happened during that period, even though you appeared to be functioning normally at the time. That’s why the statement is true. It’s not about losing consciousness or being unable to stay awake, which would be a different situation (passing out). It also isn’t about remembering everything clearly, which would be the opposite of a blackout, and it doesn’t imply you were never intoxicated.
