Which vulnerability increased for Inca terraced agriculture during prolonged drought?

💡 Explanation

Brittle failure risk increased because hydrostatic pressure behind terrace retaining walls due to saturation normally undergoes a mechanical balancing act through water flow; drought disrupts this, and lithostatic loading causes collapse, rather than enabling efficient maize photosynthesis.
