In a world where every person's shadow always points towards the nearest source of water instead of corresponding to the light direction, Keiji and Amara are standing in an open field. Keiji notices that his shadow is pointing directly at Amara, who is standing still, reading a map. What can Keiji deduce about his position relative to Amara and the nearest source of water? Respond very briefly.
Keiji's shadow is cast in the direction of the nearest source of water, but it is also pointing directly at Amara. This signifies that Amara is currently positioned between Keiji and the nearest water source. The shadow's direction implies a straight line from Keiji, through Amara, leading to the nearest water source. Consequently, Keiji can infer that he is farther from the water source than Amara is, and that if he were to walk towards his shadow, he would reach Amara first before continuing on to encounter the water source.
