We need to infer Beatrix's belief about the location of the sturdy tablet based on events and possibly knowledge. Timeline:

8:00 Beatrix moved the sturdy tablet into the south stairwell.
8:01 Opal took the sturdy tablet and placed it in the storage room.
8:02 Opal carried the bright tablet to the south stairwell.
8:03 Beatrix took the bright tablet and placed it in the reception area.
8:04 Piers reorganized papers.
8:05 Piers refilled coffee.
8:06 Beatrix checked email.

We need to know what Beatrix believes about the sturdy tablet's location at 8:06 (or after). She moved it at 8:00 to south stairwell. She may not have observed Opal taking it at 8:01. Does she know Opal moved it? The narrative says "At 8:01, Opal took the sturdy tablet and placed it in the storage room." But does Beatrix know that? The question: "Where does Beatrix believe the sturdy tablet is?" We assume she only knows events she observed. She moved it at 8:00, then later she didn't see Opal take it. So her belief is that it's still in the south stairwell. Unless she later observed something else. She later at 8:03 took bright tablet, not sturdy. So her belief remains south stairwell. So answer: south stairwell.
