The most accurate response that describes how the Crusades impacted changes in European society and spurred the Renaissance is: "Crusaders brought back classical ideas and renewed interest in intellectualism."
The Crusades facilitated contact between Europe and the Islamic world, which had preserved and advanced classical knowledge from ancient Greece and Rome. This exchange of ideas contributed to a renewed interest in learning, science, philosophy, and the arts in Europe, ultimately playing a significant role in the emergence of the Renaissance.
