Nice quiz. I have a few suggestions for improvements. The man who "discovered that America wasn't Asia" was not Vespucci because he did not know that they were not connected. Vitus Bering should be credited with that discovery. Please accept "Magellan" as an answer. Why do you say that Barents survived a winter at the North Pole? he never got there. Also check spellings on your answers as some are dubious.
