Which constraint necessitates complex terracing in pre-Columbian Andean agriculture?

💡 Explanation

Mountainous terrain limits the available horizontal land needed for cultivation; terrace construction employs 'contour plowing,' intercepting water and slowing erosion. This increases arable land and harvest yield, because terraces prevent immediate water runoff rather than passively accommodating poor soil.
