Explanation:

This is the source of information that did not help Prince Henry learn about Africa. Prince Henry was able to learn from many sources, such as captives that were brought back, maps that were created based on earlier voyages and prisoners that gave him information about Africa. However, he relied on secondary information, as he was not able to achieve firsthand information of land features past Cape Bojador.
