Answer:
Brasilia is located in the interior while Rio de Janeiro is on the coast, with a benefit of Brasilia's location being the development of the interior.
Step-by-step explanation:
Brasilia is an interesting case. The city has been specially built from scratch to be the capital of Brazil. The government planned to decentralize the country and to develop parts of the country that were underdeveloped. This would have also eased up the pressure and problems that coastal cities like Rio de Janeiro have had.
While the idea has been good, and the city became inhabited, with people of high profile living along with ordinery people, without segregation of the city by class, it didn't turn out as wanted. Brasilia was intended primarily to develop the interior of the country and to attract more people to the interior. This happened in the first years after the establishment of the city, but people soon started to move back toward the coast because economically the interior was simply not able to match the coastal area.
