Which risk increases for ancient Inca rope bridges during seasonal ice formation?

💡 Explanation

Increased ice loading causes excessive rope fiber tensile stress because the ice adds weight and strain exceeds material limits, therefore the ropes are more likely to snap, rather than deck issues, anchor failure, or fiber decomposition dominated by other environmental factors.
