Richard Nixon i think sorry if its wrong
1. I would say Beneficial because when he discovered the "west Indies" he brought back much treasures and gained spain lots of territory.
2. It would have been different because he could've just asked another country or he could have gave up and someone else might have found the new world.
3. This question is up to you...
Leyes de Burgos might be the answer
My Best answer is James Oglethorpe who founded the colony.
