Model reasoning

We need to parse the narrative. It's a timeline of actions. The question: "Where does Nadia believe the blue box is?" We need to infer Nadia's belief based on events. The only mention of blue box: at 8:00, Kira carried the blue box to the reception area. At 8:01, he took the blue box and placed it in the south stairwell. No other mentions. Nadia's actions involve cracked tablet, not blue box. But belief could be derived from what Nadia observed? We have no explicit statement of Nadia's belief. So likely unknown. However maybe Nadia saw something? At 8:15 Nadia took the cracked tablet and placed it in the cafeteria. She might have observed earlier events? She could have seen Kira moving blue box? Timeline: 8:00 Kira moved blue box to reception. 8:01 moved to south stairwell. Nadia's first action at 8:15. She could have knowledge of prior events? Not given. So we cannot infer belief. So answer "unknown".
