Which threat increased for Inca rope bridges during wetter highland seasons within the Andes?

💡 Explanation

Increased moisture saturates the natural fiber ropes, decreasing tension; the bridge's natural frequency lowers, because of increased inertial mass leading to resonance when excited by wind or pedestrians, therefore leading to oscillations, rather than improving stability, as decay accelerates
