Without revision, a student is likely to remember only 25% of information after a certain period.

This question refers to the forgetting curve, a concept developed by Hermann Ebbinghaus. It describes the rate at which memories are lost over time if there is no attempt to retain them.

Understand the forgetting curve.
The forgetting curve shows that a significant amount of newly learned information is forgotten very quickly, especially within the first 24 hours, if it is not reviewed.
Evaluate the options based on the forgetting curve.
According to Ebbinghaus's research, without revision, a person can forget approximately 50-80% of new information within the first day. This means they would only remember about 20-50% of the information. The option of remembering "only 25%" aligns closely with the rapid decline in memory retention observed within the first 24 hours. After longer periods (3, 6, or 10 days), the percentage of remembered information would typically be even lower than 25%.
Select the best option.
The most accurate timeframe for remembering only about 25% of information without revision is after 1 day.

The final answer is $\text{A. 1 day}$
