Model reasoning

We need to infer Silia's belief about location of large folder based on his observations. Timeline:

8:00 Silas brought large folder to gym. So at that moment he knows it's in gym (he placed it there). 8:01 he took large folder and placed it in workshop. So he knows it's now in workshop. 8:02 Juno took large folder and placed it in north stairwell. At 8:02, he (Juno?) noticed this from across the room. Actually "At 8:02, he noticed this from across the room." Who is "he"? Likely Juno? The sentence: "At 8:02, Juno took the large folder and placed it in the north stairwell. At 8:02, he noticed this from across the room." Could be Juno noticing himself? Or maybe Kira? But pronoun ambiguous. Usually "he" refers to Juno (male). So Juno noticed his own action? Not relevant to Silas. Silas didn't see that. So Silas's belief remains that folder is in workshop (since he moved it there at 8:01). At 8:03 Kira moved the large folder into the workshop. So Kira moved it into workshop (maybe from north stairwell). But Silas didn't see that. He still believes it's in workshop (still correct). At 8:04 Juno brought bright folder elsewhere. Not relevant. So Silas's belief about large folder location is workshop. He hasn't observed any later moves. So answer: workshop.
