Model reasoning

We need to parse the timeline and infer beliefs. The question: "Where does Nolan believe the red box is?" We have events with timestamps. Need to consider what Nolan knows. Nolan only appears at 8:02 moving the red box into the basement. No other events involve Nolan. So Nolan's belief after 8:02? He moved it to basement, so he believes it's in basement. Unless later events he didn't witness could change his belief? He might not know later moves. So answer: basement.
