1 - In in the exactly process of writing an essay for my specializaiton about the teaching of art here (more in the sense of what and how, than where) right now...Here art is mostly focused in elementary school. Secondary levels those days are directed for the preparation to university, which means, the competition to be trained for the working marketing. Art is not Law, you know, It is not a career :P
2 - Yes. But they are not many neither powerful enough...
3 - Yes. Although for example, there is not a Cinema university, so you have to get a curse that by chance teaches you to make movies and look for extra curses...
4 - Yes, but here it does not mean that much.
5 - The public does not have any idea and they would ask back what is modern, what is contemporary, etc. Some do not even reckon that their popular art is art. Now some can make the classification in the sense of historic (Barroco style often and relate it to the historical cities here and a famous artist named Aliejadinho), they may relate the Modern art to their symbols here (Niemeyer, Brasilia, the Museum in Sao Paulo and the Week of Modern Art in 1922, even if they can not related Villas-Lobos or Humberto Mauro - musician and moviemaker- with the same movement for example).
6 - Perhaps that question would need a bigger memory for some, but here is not that much, because we lived a Militar dictatorship from 1964 to 1985, and in 1969 an act of the Militar Governament they made all media in the country to be rulled by censorship.
Funny enough, this period produced the Music of Chico Buarque de Holanda, Caetano Velloso, among others who are very critic, but with great poetry are able to make the music pass by the "experts" of the censorship group or the high allegorical movies of Glauber Rocha, that was so allegorical that a general said to not censor it at all, because No one in the public would understand it anyways.
We also had the Getulio Vargas dictatorship from 30 to 45, Vargas did not liked critics to him, but he was a bit wiser (and facist and urbanist) so he instead of fighting the modernist movemment hired them to work for "Brazil", which worked very well, because both had the idea of Modern Brasil and national integration behind their "plans". The idea of Vargas - more politc that the militars - was to keep the enemies close to him, make them fight among themselves and keep to be the center of attention - turned the history of censorship during his period not as big.
During the militar regime they are however a disaster. They destroyed the artistic evolution here, from the country in the 60's that are up with Europe, with great musical inovation, great works of cinema, the hand of state smoothered it and when it was over in the 80's we had a period of 10 years without a national production of movies and all our music turned to be either the old guard from before the 70's or the attemt of copy of US music...Gladdly freedom already turned us back. So, any daily pappers you would see poems of Camoes or cooking recipies that are used at last time to replace a notice that was not allowed to go on. I remember movies such Clockwork Orange who arrived here with more than a half hour cut and black balls in the screen trying to cover the genitals in the movie. Je Vous Sale, Marie scandal was much bigger and funny enough not because the religious scandal that it could had, but because "it was a scandal that could make people do scandals in group" and was all cut down. There was a TV soap opera , basead on a play from Dias Gomes (another allegory to make critic of the public power using a false hero to mobilize the public) was banned from the tv in 1978. There was musics that never got in the radio stations because they are afraid to get the attention of the governament and even footballers suffered a bit, for Example, Reinaldo a more active voice with ties with intelectuais here who are sided (in the sense of communist ideology) with Cuba was never accepted by the governament and many related his non-call in 1982 World Cup to the pressure of the Governament.
There is more stories (altough some of the stories of censorship are due the moralism of society, like naked scenes cut or cursing edited in music, etc.) but I would need a research to give details.
Now a funny thing, you may find lovely, some of the censorship was done by a old lady. The censor did not cared much for it so he asked his old old mother what was her opinion. So sometimes an artist get away with his work because he was "a so good young boy, my son. "
I have discovered a long ago, that for Some reasons Brazil always find a way to make everything happens in very odd way that in centuries to come people will think it is comedy that happened here.
