← HistoryWhich risk increases during the siege of a wooden rope suspension bridge within a Viking-era fortification?
A)Fire spread and structural collapse✓
B)Cable weathering due to saline air
C)Foundation sinking into peat bogs
D)Decking erosion by seawater splash
💡 Explanation
Fire spread and structural collapse increases because the fire's rate of energy release causes pyrolysis accelerating wood combustion, weakening suspension ropes above. Therefore structural integrity is compromised, more rapidly than water or ground erosion, which are far slower mechanisms.
