Which outcome occurred when the Roman road network experienced settlement?

💡 Explanation

Settlement induced differential movement triggers cracking via differential compaction. This increases the **stress concentration** because sections sink unevenly, therefore requiring more maintenance, rather than improved siege weapon deployment whose function isn't related.

• Which consequence resulted from high phosphorus content in early Chinese cast iron crossbow triggers?
• Which increased risk resulted from repeated pedestrian crossings overloading early rope bridges?
• Within Mughal gardens, which outcome accelerates water feature degradation due to capillary action?
• Which limit was increased when fore-and-aft sails replaced square sails on merchant ships?
• Which risk increases as Byzantine silk production scales up due to raw material limitations?
• Which long-term degradation risk uniquely threatens 'pietra dura' in humid environments, such as those found extensively in historical Mughal gardens?
