How was the Arab trade network connected to the return of Greek philosophy to Europe? The Arabian trade routes provided a safe method of travel. Philosophers took advantage and journeyed along the routes, sharing their ideas.
B Trade brought great prosperity to the Arab Empire, which gave caliphs the wealth to sponsor philosophers and scholars at a time when Europe was struggling.
C Trade with China brought papermaking to the Arab Empire. This technology allowed Arab scholars to record their translations of Greek philosophical works and to share their translations with the West.
D Arab contact with the Byzantines exposed them to Greek philosophy, and the Arabs incorporated those ideas into their own belief system. Trade with Europe then returned those ideas as Europeans adopted the Arab system.
