How good are you at Brazilian geography?

Hi Folks,

It´s pretty common in English to use expressions related to the points of the compass: north, south, east and west. A number of useful compound words are also common:
1. In the direction of: northwards, suthwards, eastwards, westwards -- and also northeastwards, etc. for points in-between.
2. In comparative terms: northernmost, southernmost, etc.

So here´s the test. Without any reference to maps (no cheating now!!), can you complete the following sentences?
(Warning: More than one answer may be possible.)

1. Above the equator, the ______________ state capital is ________________.
2. Traveling ________________ from Brasília, the first state capital you hit is _________________.
3. Except for Porto Alegre, the _______________ state capital would be ________________.
4. Below the equator and on the coast, the ___________________ state capital is _________________.
5. You can practically walk __________________ from the Tropic of Capricorn to be in downtown _______________.

Good luck and don´t get lost!
