Fictional library archive L has four cards. L1: named Moon, fixed gate-frame G, morning on archive date 6, beside the left post, thin lit appearance. L2: same named Moon and G, later on date 6, above the right post, thin lit appearance. L3: date 19, same named Moon, near-full lit appearance; position/reference not supplied. L4: date 20, a written question only; observation explicitly not attempted. Visitor Noor asks where the Moon was against G on date 6. Visitor Sam asks how its lit appearance differed between dates 6 and 19. No cards are photographs or current local forecasts.
Question 1: Which cards help Noor? Tell or show why.
Question 2: Which cards help Sam? What changed in their notes?
Question 3: What does L4 tell us? What does it not tell us?
Question 4: Make a short useful answer for one visitor. Keep its source.
