Model reasoning

We need to infer Noor's belief about location of red wrench based on events. Timeline:

8:00 Nolan took red wrench and placed it in server room.
8:01 David brought red wrench to cafeteria.
8:02 Nolan took worn box and placed it in server room.
8:03 David moved worn box into cafeteria.
8:04 Noor reorganized some papers on the desk.
8:05 he refilled a cup of coffee.

Noor's actions are unrelated to wrench. Does Noor have any knowledge of wrench location? He was not present for earlier events? Not specified. Usually belief is based on what they observed. Since Noor only reorganized papers and refilled coffee, no mention of seeing wrench. So he has no belief: unknown.

Thus answer: unknown.
