At 8:00, Tamsin took the heavy wrench and placed it in the south stairwell. At 8:01, Greta moved the heavy wrench into the supply closet. At 8:02, Tamsin took the bright box and placed it in the wine cellar. At 8:03, Greta brought the bright box over to the reception area. At 8:04, she reorganized some papers on the desk. At 8:05, Tamsin refilled a cup of coffee.

Where does Oscar believe the heavy wrench is? Answer with only the location name (or 'unknown' if they have no belief).

unknown

Model reasoning

We need to infer Oscar's belief based on the story. The story mentions Tamsin and Greta moving objects. No mention of Oscar. So Oscar has no belief about heavy wrench location. So answer "unknown".
