Model reasoning

We need to infer Aria's belief about location of green box based on events and possibly perspective. Timeline: 8:00 Tamsin brought green box to front office. 8:01 she moved green box into greenhouse. So after 8:01, green box is in greenhouse. At 8:02 Oscar brought narrow basket to front office. 8:03 she (Oscar? "she") brought narrow basket to greenhouse. At 8:04 Aria reorganized some papers on the desk. At 8:05 she refilled a cup of coffee. So Aria's actions are at desk and coffee, no mention of green box. Does Aria have knowledge of green box movement? She might have observed earlier? Not specified. Usually belief is based on what they have observed. Since no mention that Aria saw Tamsin moving the box, she might not know. So she might think it's still at front office (if she saw initial placement but not later move). But we have no info about her observation. The question: "Where does Aria believe the green box is?" We need to infer based on given info. Since Aria's actions are unrelated, we have no info about her belief. So answer "unknown".
