Which constraint primarily dictated terrace construction style in ancient mountainous regions?

💡 Explanation

When constructing terraces, soil erosion is a key factor because heavy rainfall on sloping land rapidly washes away topsoil leading to agricultural failure. Therefore, terrace styles prioritized managing water runoff, rather than sunlight, access, or material which are secondary constraints.
