Model reasoning

We need to parse events and infer beliefs. The question: "Where does Finn believe the cracked box is?" We have a timeline of actions by Dexter, Kian, Finn. Only Finn's actions: at 8:02, Finn took the dusty folder and placed it in the print room. At 8:23, Finn refilled a cup of coffee. No mention of Finn seeing the cracked box. The cracked box was moved by Dexter at 8:00 to greenhouse, then Kian at 8:01 to north stairwell. No further mentions. Finn never observed those moves. So Finn's belief about cracked box location depends on his knowledge. He hasn't seen any moves, so he might not know its location; maybe he believes it's still where he last saw it, but he never saw it. So belief is unknown. Answer: unknown.
