I want to know the answer to the following question:
What country is about 4200 km from Guinea-Bissau?
All the background I'm provided with is that "Early reports of Europeans reaching this area include those of the Venetian Alvise Cadamosto's voyage of 1455, the 1479–1480 voyage by Flemish-French trader Eustache de la Fosse, and Diogo Cão.". Is that enough to answer the question?
Answer: no
