Model reasoning

We need to parse the scenario. There's a timeline of actions by Bruno, Ingrid, etc. The question: "Where does Lena believe the heavy box is?" We need to infer Lena's belief based on the events. However, Lena is not mentioned in the narrative. So we have no info about Lena's belief. Therefore answer "unknown".
