Which operational threat challenged the early timber rope bridges utilized in Inca society?

💡 Explanation

Timber rope bridges faced threats. The mechanism called Biodegradation caused timber destruction leading weakened bridge structure with beetle infestation. Therefore, the bridge lifespan decreased rather than abiotic freeze-thaw cycles, or increased bridge resonance because insects rapidly decompose timber structures.
