Model reasoning

We need to infer beliefs. Timeline: At 8:00 Sofia brought dusty wrench to greenhouse. At 8:01 Jamal took dusty wrench and placed it in loading dock. So after 8:01, dusty wrench is in loading dock. At 8:02 moved narrow box into loading dock. At 8:03 carried narrow box to greenhouse. At 8:04 reorganized papers on desk. At 8:05 Tamsin refilled a cup of coffee. No mention of Tamsin seeing wrench. So what does Tamsin believe? She likely hasn't observed any of these events. So she has no belief about wrench location => unknown. Answer: unknown.
