                                    Why use biofuels for aviation?
The aviation industry has seen huge growth since its beginning. Today, more than two billion people enjoy the social and economical benefits of flight each year. The ability to fly conveniently and efficiently between nations has been a catalyst for the global economy and has shrunk cultural barriers like no other transport sector. But this progress comes at a cost.
In 2008, the commercial aviation industry produced 677 million tones of carbon dioxide (CO2 ). This is around 2% of the total man-made CO2 emissions of more than 34 billion tones. While this amount is smaller compared with other industry sectors, such as power generation and ground transport, these industries have viable alternative energy sources currently available. For example, the power generation industry can look to wind, hydro, nuclear and solar technologies to make electricity without producing much CO2 . Cars and buses can run on hybrid, flexible fuel engines or electricity.
-powered trains can replace
locomotives.
The aviation industry has identified the development of biofuels as one of the major ways it can reduce its greenhouse gas emissions. Biofuels provide aviation with the capability to partially, and perhaps one day fully, replace carbon-intensive petroleum fuels. They will, over time, enable the industry to reduce its carbon footprint significantly.

     An amiable German social sciences teacher has to teach his children about an autocratic government. The children at first seem bored, not wanting to hear any more about The Third Reich and Nazism. The teacher is surprised. "We're too knowledgeable to ever fall into something like that again," say the students. The teacher then decides to show the children what it's like to live in an autocracy, and sets up a simple experiment in class. They elect a leader (him) and he begins to instill in them (merely as an examplE) the virtues and practices that accompany an autocracy ("Strength through discipline", "Work as one"). The students take to it, and become obsessed with it. Soon, what was a simple classroom experiment grows to a social entity all it's own, with the teacher not sure if he can reverse the effects. 

     The film was very well acted and written, and was seriously creepy. It showed how - easily a society could fall into fascism, if presented to the society in the correct way. Watching the film, I understood why the students enjoyed the new system, but was also privy to the horrors that come with it. A shocking and powerful film. The way the different children reacted and how such a seemingly innocent experiment profoundly affected their lives was incredible and horrifying. Vogel gives a powerful performance as an idealistic teacher who isn't aware of the influence he has on others. Worth seeing.

Leia abaixo o diálogo entre Severino e Mestre Carpina, retirado de Morte e vida Severina, de João Cabral de Melo Neto.

Leia a abertura e um trecho final da crônica É chato ser brasileiro!, de Nélson Rodrigues.

Dizem que o Brasil tem analfabetos demais. E, no entanto, vejam vocês: – a vitória final, na Copa da Suécia, operou o milagre. Se analfabetos existiam, sumiram-se na vertigem do triunfo. A partir do momento em que o rei Gustavo, da Suécia, veio apertar as mãos dos Pelés, dos Didis, todo mundo, aqui, sofreu uma alfabetização súbita. Sujeitos que não sabiam se gato se escreve com ―x‖ iam ler a vitória no jornal. Sucedeu essa coisa sublime: — analfabetos natos e hereditários devoravam vespertinos, matutinos, revistas, e liam tudo com uma ativa, uma devoradora curiosidade, que ia do ―lance a lance‖ da partida até os anúncios de missa. Amigos, nunca se leu e, digo mais, nunca se releu tanto no Brasil.

E a quem devemos tanto? Ao escrete, amigos, ao escrete, que, hoje, é o meu personagem da semana, múltiplo personagem. Personagem meu, do Brasil e do mundo. Graças aos 22 jogadores, que formaram a maior equipe de futebol da Terra, em todos os tempos, graças a esses jogadores, dizia eu, o Brasil descobriu-se a si mesmo. Os simples, os bobos, os tapados hão de querer sufocar a vitória nos seus limites estritamente esportivos. Ilusão! Os 5 x 2, lá fora, contra tudo e contra todos, são um maravilhoso triunfo vital de todos nós e de cada um de nós. Do presidente da República ao apanhador de papel, do ministro do Supremo ao pé-rapado, todos, aqui, percebem o seguinte: — é chato ser brasileiro!

Sobre a crônica, considere as seguintes afirmações.

I - A vitória na Copa do Mundo de Futebol, na Suécia, em 1958, manteve o sentimento de inferioridade do brasileiro em relação ao inglês.

II - O cronista destaca o efeito da vitória da seleção brasileira de futebol como forma de superar o sentimento de inferioridade.

III- A vitória e o reconhecimento de Didis e Pelés permitiram ao Brasil descobrir a si mesmo.

Quais estão corretas?

     Rhapsody is a foot-stomping celebration of Queen, their music and their extraordinary lead singer Freddie Mercury, who defied stereotypes and shattered convention to become one of the most beloved entertainers on the planet. The film traces the meteoric rise of the band through their iconic songs and revolutionary sound, their near-implosion as Mercury's lifestyle spirals out of control, and their triumphant reunion on the eve of Live Aid, where Mercury, facing a lifethreatening illness, leads the band in one of the greatest performances in the history of rock music. In the process, cementing the legacy of a band that were always more like a family, and who continue to inspire outsiders, dreamers and music lovers to this day.
