Which outcome contributed to the long-term stability of Inca masonry structures?

💡 Explanation

Dry-stone fitting relies on frictional interlocking and redistribution of stresses rather than rigid bonding; therefore, seismic activity causes small shifts without collapse, because the energy dissipates through friction, rather than concentrating stress like mortar would.
