Which limit was addressed, and design advanced, when Viking ships used 'yarn twist' for ropes?

💡 Explanation

Increased longitudinal strength occurred via yarn twisting, because maximizing frictional adhesion within the fibers required controlling twist rate. Higher rope tension strength then improved the maximum sail size; therefore, A, rather than timber fatigue or efficiency, resulted.
