One morning, Lisa left for a swimming class at 9 AM. She spent 2 hours at the pool practicing her strokes. Afterward, she headed home. What time did Lisa get back home?

Can we find out when Lisa got back home?

A. Yes, we can calculate the time.
B. No, information is missing in the question.

Answer: (B)

The question doesn’t provide information about how long it took Lisa to travel to the pool and back home. Without this information, we cannot accurately determine what time Lisa got back home.
