Don't take me too seriously Sono :-) You are right. I went to school in both, South and North America, and there are some funny differences in the way they teach things. In South America you learn that "America" is a continent that is divided in three: South, Central and North America. In Spanish the word "American" or "Americano" is not a Starbucks drink, but rather the equivalent to 'European". If you are born in the continent of America, you are an "American" by definition regardless of the region you are from.
When I went to University here in Canada, I had a major argument with an (American) Pol Science teacher who was livid at me because I told him that he was as American as any guy from Chihuahua Mexico, Machali Chile, or Muy Muy Nicaragua. That argument didn't end well for me because he said that there were only two "Americas", North and South but he would not tell me where Panama, Costa Rica, Nicaragua, etc were located provided that in English, "America Central" or Central America does not exist for "teaching purposes".
I am not sure why Manaos was chosen as a host city. Really F UP idea. Manaos is the equivalent to Winnipeg, Manitoba in Canada: Same heat, same humidity, same deadly mosquitoes plus giant snakes all over the place and drug-addicted, knife wielding thieves :-)
Good luck!! lol
