Which risk increases when wooden scaffolding used during ziggurat construction experiences repeated wetting and drying cycles?

💡 Explanation

When wooden scaffolding undergoes repeated wetting and drying, biological decomposition from fungal growth accelerates because moisture promotes fungal activity, weakening the wood's cellular structure over time. Therefore fungal decomposition results, rather than fracture, creep, or oxidation which require different environmental exposure and material properties.
