In a room with a single small window high up on the wall, Kairav, who is standing, can see the sun through the window. However, Marisol, who is much shorter and sitting on the floor, cannot see the window at all. If both Kairav and Marisol remain in their same positions in the room but Marisol asks whether the sun has set or not, how can Kairav respond based on what they can see, and why?
Kairav can inform Marisol that the sun has not set because he can see the sun through the high window from his standing position. Since Kairav's line of sight is above Marisol's and he has a clear view of the window and the sun from his vantage point, while Marisol cannot see the window from her lower, seated position, it is a matter of Kairav's view being unobstructed due to his height and standing position. This indicates that the sun is still above the horizon as visible from that window, despite Marisol's position not allowing her to confirm this directly.
