Why were memory and experience important in regular seasonal journeys of pastoralists?

Correct answer: They knew when a route, water source and pasture would be useful

Seasonal pastoral journeys required more than physical movement; they required reliable knowledge of landscapes. Pastoralists had to remember which route was safe, when a water source was likely to contain water, and which pasture would provide enough fodder during a particular season. Much of this knowledge came from repeated travel, observation, and teaching within families and communities. It helped them avoid unsuitable areas, protect animals, and plan the next stage of movement without modern maps or daily official instructions.

Option A states this environmental knowledge clearly. The other choices deny the need for memory, wrongly make the government responsible for every route, or give animals an impossible ability to read maps. Experience was not a minor convenience; it was essential for making seasonal movement successful. Therefore knowing the timing and usefulness of routes, water, and pastures makes A correct.
