Which 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.
