We need to track Elliot's beliefs about where the heavy tablet is based on his actions and observations? The scenario gives events; we must infer what each person knows/believes after their own actions? Typically these puzzles ask: given sequence of moves by different people, what does a particular person believe about location of an object, assuming they only know about moves they performed or observed? Usually they know only their own actions and maybe they see others? Not specified. Likely assumption: each person only knows about moves they themselves performed; they don't know about others' moves unless they witness them. But we need to interpret typical "belief" puzzles: If someone moves an object, they know where they put it. If they later move it again, they update. They don't know about others moving it unless they see it. So we need to compute Elliot's belief after all events up to time 8:13.

Let's list events with actors:

8:00 Elliot carried heavy tablet to break room.
=> Elliot believes tablet at break room.

8:01 Oscar brought heavy tablet to south stairwell.
Elliot didn't witness? Probably not; so Elliot still believes at break room (unless he sees Oscar moving? Not stated). We'll assume he doesn't know.

8:02 Talia carried heavy tablet to workshop.
Elliot unaware.

8:03 Elliot moved heavy tablet into meditation room.
Now Elliot knows he moved it from wherever he thought it was (break room) to meditation room. So his belief updates to meditation room.

8:04 Oscar carried heavy tablet to wine cellar.
Elliot unaware.

8:05 Elliot took heavy tablet and placed it in supply closet.
Elliot knows he moved it from meditation room to supply closet. Belief = supply closet.

8:06 Talia carried heavy tablet to wine cellar.
Elliot unaware.

8:07 she moved the heavy tablet into the meditation room.
(Talia moves it to meditation room). Elliot unaware.

8:08 Oscar moved heavy tablet into courtyard.
Elliot unaware.

8:09 Elliot moved heavy tablet into break room.
Elliot knows he moved it from supply closet to break room. Belief = break room.

8:10 Talia moved the large box into the south stairwell. (Note: now object changes to large box, not heavy tablet.) This event involves large box, not tablet. Elliot may not be aware? He might see Talia moving a large box but that's irrelevant to tablet belief.

8:11 he carried the large box to the gym. (Who is "he"? Likely Oscar? Actually previous subject was Talia? At 8:10 Talia moved large box; then 8:11 "he carried the large box to the gym." Could be Oscar? Not sure. But irrelevant to tablet.)

8:12 she reorganized some papers on the desk. (Talia?)

8:13 she refilled a cup of coffee.

Thus Elliot's last known action regarding tablet was at 8:09 moving it to break room. After that, no further tablet moves by Elliot. He hasn't seen any others moving tablet after 8:09? Let's check: after 8:09, events: 8:10 Talia moved large box (not tablet). 8:11 he carried large box (not tablet). 8:12 she reorganized papers. 8:13 she refilled coffee. No tablet moves after 8:09. So Elliot's belief remains that tablet is in break room.

Thus answer: break room.
