<s>[INST] The occupants of a small, isolated village have developed a disease that causes complete memory loss every three days. Because of this disease, the inhabitants of the village manage to keep track of their experiences over time. They stitch patterns onto cloth to convey messages to their future selves. Everyone in the village knows how to read and write, and so the villagers can simply write instructions to themselves about what to expect in the three days following a memory loss. What type of pattern is the memory loss for people in the village?[/INST]
