Imaginary Marsh Desk's selected question is “Did the visible water on this same open patch change between story morning and afternoon?” Reporter Fia records visible water in the morning; reporter Teo records no visible water in the afternoon. They describe the same named patch and indoor viewpoint. Other weather details and simultaneous reports from two people are not supplied. No real peer activity happened here.
