← HistoryWhat consequence accompanied increased bridge spans when rope bridges were employed during the Inca Empire's expansion?
A)Heightened susceptibility to synchronous oscillation✓
B)Reduced material dependence upon local resources
C)Decreased sensitivity to temperature variation
D)Minimized vulnerability to foundation settling
💡 Explanation
Longer rope bridge spans experienced heightened susceptibility to synchronous oscillation because increased flexibility induces greater amplification of rhythmic forces; therefore amplified oscillations caused structural weakening, rather than offering benefits like reduced resource dependency.
