• Which limit was increased when fore-and-aft sails replaced square sails on merchant ships?
• Which consequence results when longship hogging develops mid-voyage?
• Which navigational error increases if an astrolabe's alidade offset isn't algebraically accounted for when determining angles relative to true zenith?
• Which consequence resulted from quipu knotting errors during Inca bridge construction budget calculations?
• Which outcome occurred when medieval longship sails experienced excessive heeling?
