← HistoryWhich challenge increased for Inca suspension bridges after a wet season?
A)Anchorage slippage on waterlogged ground✓
B)Cable fraying from ice formation
C)Decking rot increased foot instability
D)Increased livestock trampling risk existed
💡 Explanation
Increased saturation weakened the pirca retaining walls because the soil underwent liquefaction. Because the anchor points couldn't reliably hold the ropes, they risked slipping. They were vulnerable to mudslides rather than simple decay, therefore liquefaction mattered more than ice.
