I want to know the answer to the following question:
What did Christopher Columbus discover in 1492?
All the background I'm provided with is that "After his death, exploration continued; Bartolomeu Dias (d. 1500) went around the Cape of Good Hope in 1486 and Vasco da Gama (d. 1524) sailed around Africa to India in 1498.". Is that enough to answer the question?
