Which challenge did ancient Andean terrace agriculture use strategically placed stones to solve effectively?

💡 Explanation

Stones were strategically placed in terraces to manage drainage and prevent water erosion because the stones slowed water flow which allowed soil to stabilise better. Therefore, soil erosion was managed, rather than increased pH, fighting pests, or improving pollination which require different environment control methods.
