Old World events which sparked exploration included all except:

Question

Spanish war with the Muslims
Prince Henry's school
the Crusades
Polo's journeys

Answer 1

The event that did not specifically spark exploration in the Old World is "Spanish war with the Muslims." While the Reconquista, which involved the Spanish wars against Muslim kingdoms, had an impact on the political and social landscape of Spain, the other events listed—Prince Henry's school, the Crusades, and Polo's journeys—were more directly influential in promoting exploration and expanding knowledge about distant lands.
