Model reasoning

We need to infer Jasper's belief about location of small box based on events. We have timeline of actions by various people. No mention of Jasper directly. We need to consider that Jasper may have observed some events? The question: "Where does Jasper believe the small box is?" We need to infer based on what Jasper could have seen. No info about Jasper's observations. Possibly Jasper is not mentioned, so unknown. However maybe Jasper is one of the people? Not listed. So likely unknown. Answer: unknown.
