← HistoryWhich consequence results from stone's microcrack propagation in the Inca masonry?
A)Increased quipu knot deterioration
B)Elevated terracing erosion rates
C)Reduced bridge cable lifespan
D)Accelerated structural collapse vulnerability✓
💡 Explanation
Inca stone masonry experienced structural issues due to microcrack propagation—a form of brittle fracture—because cracks concentrate stress, therefore the building becomes more vulnerable to collapse, rather than cable degradation or changes to erosion affecting terracing.
