← HistoryWhich consequence occurs when Incan quipu strings degrade?
A)Crop yield data becomes irretrievable✓
B)Bridge cable strength is compromised
C)Terrace erosion accelerates rapidly
D)Aqueduct flow rate decreases gradually
💡 Explanation
Loss of quipu leads to irretrievable yield records because the knots and cord colors encoded agricultural data using base-10 positional notation. Reconstruction is rarely possible; therefore, crop planning is hampered rather than bridge failure arising from suspension weakness.
