Question

hich is an example of how non-European cultures made the era of European exploration possible?

European explorers relied on African, Asian, and Native American sailors to crew their ships.
European explorers used non-European inventions such as the astrolabe, the compass, and gunpowder.
Asian diplomats initially invited and welcomed European trading expeditions to their lands.
Asian eagerness for knowledge of Christianity gave Europeans an excuse for commercial exploration.
