Model reasoning

We need to parse the timeline and infer beliefs. The question: "Where does Tobias believe the shiny tablet is?" We have events about shiny tablet: at 8:00 Xiomara took the shiny tablet and placed it in the lobby. At 8:01 Quentin carried the shiny tablet to the print room. No further mentions of shiny tablet. Tobias only appears at 8:25 checking email. No direct observation of tablet. Belief formation: We need to consider what Tobias knows based on events he could have observed? Usually these puzzles assume agents have perfect knowledge of events they are present for, but not others. However we have no info about who sees what. Might be that each person only knows actions they performed or observed? The puzzle likely expects that Tobias hasn't seen the tablet moved after 8:01, so he believes it's in the print room (last known location). Unless he could have seen later moves? No later moves of tablet. So answer: print room.

Thus answer: print room.
