Analysis:
The question asks who believes that we can learn important things from the past. We need to find the person who expresses this idea in their statement.
- Oskar: Focuses on current subjects and job preparation.
- Mary: Mentions learning about the past to understand the world today and find answers to modern problems.
- Freeda: Discusses classical languages and their usefulness in today's world, but doesn't explicitly focus on learning 'things' from the past in a broad sense.
Mary's statement directly addresses learning about the past for understanding the present.
