“Frau Diller era uma mulher irritadiça, de óculos grossos e olhar implacável. Tinha criado esse olhar nefando para desestimular a própria ideia de alguém roubar sua loja, que ela ocupava com postura militar, voz gélida e até uma respiração que cheirava “heil Hitler". A loja em si era branca e fria, completamente exangue. A casinha espremida ao seu lado tremia com um pouco mais de severidade do que as outras construções da Rua Himmel. Frau Diller administrava esse sentimento, servindo-o como o único produto grátis de suas instalações. Ela vivia para sua loja, e sua loja vivia para o Terceiro Reich. Mesmo quando começou o racionamento, mais para o fim do ano, sabia-se que ela vendia por baixo do pano algumas mercadorias difíceis de obter e doava o dinheiro para o Partido Nazista".
(ZUSAK, Markus. A menina que roubava livros. Rio de Janeiro: Intrínseca, 2008. p.37.)

“Logo depois, a PF prende também Gilberto Gil. Os dois são levados para quartel da Polícia do Exército, na rua Barão de Mesquita. Passam o reveillon de 1969 na cadeia. Lá Caetano encontra outros presos, como Ênio Silveira, dono da editora Civilização Brasileira (a mesma dos livros de Bertrand Russell), que lhe empresta O estrangeiro, de Camus. Depois, é transferido para um outro quartel, em vila militar no subúrbio de Deodoro, zona norte do Rio. Na cela ao lado, Gil divide espaço com Paulo Francis, Ferreira Gullar e outros intelectuais. Caetano vai parar na barbearia do quartel e perde a cabeleira “selvagemente grande" cultivada por quase dois anos. Após dois meses na cadeia, são transferidos para Salvador e lá permanecem confinados por mais quatro meses. Proibidos de se apresentar em público e de dar entrevistas, tomam o caminho do exílio. Ao embarcar para Londres, um dos policiais afirma para Caetano:
- Não volte nunca mais. E, se pensar em voltar se entregar logo que chegue para nos poupar trabalho".

“A Assembleia-Geral da ONU aprovou nesta quinta- feira (27/04/2014) uma resolução declarando inválido o referendo realizado no início do mês no território ucraniano da Crimeia, no qual foi aprovada sua anexação à Rússia, em uma votação que as nações ocidentais disseram ter sido mais um reforço no isolamento russo. As resoluções da Assembleia-Geral não são de cumprimento obrigatório, mas representam a pressão da comunidade internacional quando aprovadas por um grande número de países".

O texto acima aborda sobre questão da Crimeia, uma área de importância econômica para Russos e Ucranianos. O impasse constatado é um resquício da Guerra Fria. Com base nos conhecimentos sobre o período da bipolarização do planeta e suas consequências, considere as a?rmativas a seguir:
I - Em 1949, diante do crescimento da tensão nas relações entre os mundos capitalistas e socialistas, foi fundado, por iniciativa dos Estados Unidos, a Organização do Tratado do Atlântico Norte (Otan). O organismo se estruturou em cima de uma aliança militar, composta originalmente pelos Estados Unidos, França, Bélgica, Canadá, Países Baixos, Dinamarca, Reino Unido, Luxemburgo, Noruega, Finlândia, Itália e Portugal. Posteriormente tornaram-se aliadas a Alemanha Ocidental, a Grécia e a Turquia, fechando o círculo do confronto oeste-leste.
II - Os EUA, o Reino Unido e a Rússia, no ano de 1994 assinaram o Memorando de Budapeste, que comprometia garantir a independência e as atuais fronteiras da Ucrânia. Neste documento a Ucrânia abdicava do terceiro maior arsenal nuclear do mundo, mantido após o fim da União Soviética.
III - No ano de 1955, houve um evento crucial, realizou-se o primeiro teste nuclear soviético, no deserto da Namíbia. Era o início da corrida nuclear entre as duas potências.
IV - Em 19 de agosto de 1991, setores conservadores do Partido Comunista e das forças armadas soviéticas sequestraram Gorbatchev, numa tentativa de restabelecer o modelo anterior à perestroika e à glasnost. Entretanto, Yeltsin mobilizou a população de Moscou e de Leningrado e conseguiu frustrar o golpe de Estado. Fortalecido, o dirigente russo proclamou a independência da Rússia e das demais repúblicas. Quando Gorbatchev foi libertado, a União Soviética não existia mais. Em seu lugar surgira a Comunidade dos Estados Independentes.

“Nosso dia vai chegar
Teremos nossa vez
Não é pedir demais
Quero justiça
Quero trabalhar em paz
Não é muito o que lhe peço
Eu quero um trabalho honesto
Em vez de escravidão
Deve haver algum lugar
Onde o mais forte
Não consegue escravizar
Quem não tem chance
De onde vem a indiferença
Temperada a ferro e fogo?
Quem guarda os portões da fábrica?
O céu já foi azul, mas agora é cinza
O que era verde aqui já não existe mais
Quem me dera acreditar
Que não acontece nada de tanto brincar com fogo
Que venha o fogo então
Esse ar deixou minha vista cansada
Nada demais".

História
“Durante mais de cem anos pairou uma onda de mentiras sobre a Guerra do Paraguai. Junta-se a essa onda de mentiras um silêncio criminoso, procurando ocultar de todas as formas possíveis o que foi aquela guerra, o que representou para os povos envolvidos e, principalmente, como, por sua causa, o Brasil e a Argentina (levando o Uruguai de contrapeso) ficaram definitivamente colonizados pelo capital inglês. Apesar de sua transcendental importância histórica – ela foi uma das causas fundamentais da queda do Império –, apesar de a Guerra do Paraguai ser o marco mais importante da nossa história e que mais repercussões teve para o povo brasileiro, faz-se silêncio. Ou mente-se".
(CHIAVENATTO, Julio José. Genocídio americano: A Guerra do Paraguai.
São Paulo: Editora Brasiliense, 1984. p.09.)
Com base no texto e nos conhecimentos sobre as motivações que levou a Guerra do Paraguai e as consequências após o conflito, considere as afirmativas a seguir:
I - O Paraguai rompeu violentamente toda uma estrutura de dominação econômica. Carlos Antonio López enfrentou os métodos britânicos e promoveu o progresso Paraguaio sem precisar de um tostão dos financiamentos ingleses. Seu método foi simples, trouxe do exterior todos os técnicos que o país precisava para implantar a base de seu desenvolvimento industrial.
II - A Argentina e o Brasil tiveram que fazer a guerra. Latifundiários e burgueses beneficiários do imperialismo econômico no Plata fizeram a guerra por um só motivo: defender os interesses econômicos dos ingleses, que os sustentava devolvendo-lhes migalhas do que roubava dos povos que iriam sacrificar-se.
III - A Guerra do Paraguai aconteceu porque Solano López queria coroar-se Imperador da América do Sul e abrir ao comércio do mundo os mais variados produtos dos trópicos e rios navegáveis para serem explorados.
IV - Em 1868 Asunción já tinha sido tomada e saqueada pelos soldados brasileiros, já havia um governo títere imposto e o Paraguai estava sendo retalhado e entregue ao imperialismo internacional. Mesmo assim, Francisco Solano López continuou a desesperada resistência, porém foi preso e exilado para a Inglaterra.

SOUTHERN HUMPBACK WHALE
INTRODUCTION
During the Australian winter, these ocean leviathans journey 3,100 miles north from their Antarctic feeding grounds to the warm tropical waters near Australia´s Whitsunday Islands. At the southern edge of the Great Barrier Reef, the 40-ton female humpbacks give birth to calves measuring 14 feet long and weighing over one ton. The Whitsundays´ sheltered bays keep the calves warm and safe from predators. During the next few months, the whales rest, sing, play and mate. The calves nurse, but the one thing the adult whales don´t do while in the tropical seas is eat. By winter´s end, adults are famished, and they head south. This life cycle is repeated throughout the Southern Hemisphere: one group migrates along the western coast of Australia, others to southern Africa and South America.
SIGHT UNSEEN
Underneath the blue Australian ocean, film crews captured the elegant rituals of southern humpbacks as they swim, sing, nurse, and play. A mother humpback whale supported her young calf from underneath, so it could breathe easier near the surface. Calves drink 130 gallons of milk a day! While baby grows fat, the mother starves for five months, her blubber stores depleting daily. Unlike the cold Antarctic waters, the seas here don´t grow rich with krill that humpbacks filer through their baleen plates. But she provides her calf with rich milk that contains some of the highest fat content of any mammal´s milk – 45 percent.
UNIQUE BEHAVIOR
Humpback males sing a unique melody, full of high-pitched chirps and whistles interspersed with deeper gurgles and moans. Each male repeats his song for hours, which likely plays a role in courtship. The song may change over time, with males singing a modified melody in consecutive years.
Whale-watching tours take advantage of the humpback´s playful and curious nature. They often approach boats and put on quite a show. As whales journey south along the eastern coast of Australia, many stop in sheltered Platypus Bay around Fraser Island – a World Heritage Site – where they display the charismatic behaviors loved by whale-watchers. The crystal blue waters give a perfect window to watch the whales twist, roll and swim upside down, emerging to breathe, slap their tails or pectoral fins on the water´s surface. Breaching whales jump nearly all the way out of the water. “Spyhopping" means their head emerges, and they peer at the surroundings with their large eyes.
STATUS/CONSERVATION
Commercial hunting in the 19th and 20th centuries decimated most whale species. Because they migrate close to shore and swim slowly, humpbacks became a popular whalers´ target, and were hunted down to a few hundred animals in the Southern Hemisphere. The International Whaling Commission (IWC) implemented a moratorium on harvesting all species starting in 1986, and in 1994, declared Antarctica´s Southern Ocean a whale sanctuary. Now numbering over 10,000 in the Southern Hemisphere, humpbacks have shown incredible resilience, but their numbers still remain a fraction of their historic abundance. Recovery of regional populations varies, and the World Conservation Union (IUCN) lists the humpback as vulnerable.
Humpbacks also have two Northern Hemisphere populations that number around 11,500 in the North Atlantic and 6,000 in the North Pacific. Northern humpbacks are genetically differentiated from the Southern Hemisphere population, and have dark bellies, while the southern humpbacks have all-white bellies. They don´t interbreed, because while the southern populations are mating and calving in the warm tropical seas, northern populations are near the polar Arctic.
OUTLOOK
The International Whaling Commission (IWC) allows hunting by indigenous cultures but bans hunting of humpback whales. Japan has long engaged in IWC-sanctioned “scientific whaling" of minke and other whales, and plans to start hunting humpbacks in 2007. “We are all concerned about Japan´s plans to add this species to the scientific whaling quota", says Dr. Scott Baker, a renowned cetacean conservation biologist. Iceland also just started commercial whaling in 2006.
Some Asian countries allow the sale of whale meat from incidental bycatch, and a whale´s value of $100,000 provides incentive for illegal harvest. Baker and colleagues used DNA to show that the whale meat being sold in South Korean shops did not match that reported to the IWC. Illegal harvest and sale of whale meat is occurring.
Australia and New Zealand have petitioned the IWC to create a South Pacific Sanctuary adjoining the Southern Ocean Sanctuary where whaling would be illegal. Thus far, it has not been approved by IWC.

At the southern edge of the Great Barrier Reef, the 40-ton female humpbacks give birth to calves measuring 14 feet long and weighing over one ton. The Whitsundays´ sheltered bays keep the calves warm and safe from predators. During the next few months, the whales rest, sing, play and mate. The calves nurse, but the one thing the adult whales don´t do while in the tropical seas is eat. By winter´s end, adults are famished, and they head south. This life cycle is repeated throughout the Southern Hemisphere: one group migrates along the western coast of Australia, others to southern Africa and South America.
SIGHT UNSEEN
Underneath the blue Australian ocean, film crews captured the elegant rituals of southern humpbacks as they swim, sing, nurse, and play. A mother humpback whale supported her young calf from underneath, so it could breathe easier near the surface. Calves drink 130 gallons of milk a day! While baby grows fat, the mother starves for five months, her blubber stores depleting daily. Unlike the cold Antarctic waters, the seas here don´t grow rich with krill that humpbacks filer through their baleen plates. But she provides her calf with rich milk that contains some of the highest fat content of any mammal´s milk – 45 percent.
UNIQUE BEHAVIOR
Humpback males sing a unique melody, full of high-pitched chirps and whistles interspersed with deeper gurgles and moans. Each male repeats his song for hours, which likely plays a role in courtship. The song may change over time, with males singing a modified melody in consecutive years.
Whale-watching tours take advantage of the humpback´s playful and curious nature. They often approach boats and put on quite a show. As whales journey south along the eastern coast of Australia, many stop in sheltered Platypus Bay around Fraser Island – a World Heritage Site – where they display the charismatic behaviors loved by whale-watchers. The crystal blue waters give a perfect window to watch the whales twist, roll and swim upside down, emerging to breathe, slap their tails or pectoral fins on the water´s surface. Breaching whales jump nearly all the way out of the water. “Spyhopping" means their head emerges, and they peer at the surroundings with their large eyes.
STATUS/CONSERVATION
Commercial hunting in the 19th and 20th centuries decimated most whale species. Because they migrate close to shore and swim slowly, humpbacks became a popular whalers´ target, and were hunted down to a few hundred animals in the Southern Hemisphere. The International Whaling Commission (IWC) implemented a moratorium on harvesting all species starting in 1986, and in 1994, declared Antarctica´s Southern Ocean a whale sanctuary. Now numbering over 10,000 in the Southern Hemisphere, humpbacks have shown incredible resilience, but their numbers still remain a fraction of their historic abundance. Recovery of regional populations varies, and the World Conservation Union (IUCN) lists the humpback as vulnerable.
Humpbacks also have two Northern Hemisphere populations that number around 11,500 in the North Atlantic and 6,000 in the North Pacific. Northern humpbacks are genetically differentiated from the Southern Hemisphere population, and have dark bellies, while the southern humpbacks have all-white bellies. They don´t interbreed, because while the southern populations are mating and calving in the warm tropical seas, northern populations are near the polar Arctic.
OUTLOOK
The International Whaling Commission (IWC) allows hunting by indigenous cultures but bans hunting of humpback whales. Japan has long engaged in IWC-sanctioned “scientific whaling" of minke and other whales, and plans to start hunting humpbacks in 2007. “We are all concerned about Japan´s plans to add this species to the scientific whaling quota", says Dr. Scott Baker, a renowned cetacean conservation biologist. Iceland also just started commercial whaling in 2006.
Some Asian countries allow the sale of whale meat from incidental bycatch, and a whale´s value of $100,000 provides incentive for illegal harvest. Baker and colleagues used DNA to show that the whale meat being sold in South Korean shops did not match that reported to the IWC. Illegal harvest and sale of whale meat is occurring.
Australia and New Zealand have petitioned the IWC to create a South Pacific Sanctuary adjoining the Southern Ocean Sanctuary where whaling would be illegal. Thus far, it has not been approved by IWC.

Humpback males sing a unique melody, full of high-pitched chirps and whistles interspersed with deeper gurgles and moans. Each male repeats his song for hours, which likely plays a role in courtship. The song may change over time, with males singing a modified melody in consecutive years.
Whale-watching tours take advantage of the humpback´s playful and curious nature. They often approach boats and put on quite a show. As whales journey south along the eastern coast of Australia, many stop in sheltered Platypus Bay around Fraser Island – a World Heritage Site – where they display the charismatic behaviors loved by whale-watchers. The crystal blue waters give a perfect window to watch the whales twist, roll and swim upside down, emerging to breathe, slap their tails or pectoral fins on the water´s surface. Breaching whales jump nearly all the way out of the water. “Spyhopping" means their head emerges, and they peer at the surroundings with their large eyes.
STATUS/CONSERVATION
Commercial hunting in the 19th and 20th centuries decimated most whale species. Because they migrate close to shore and swim slowly, humpbacks became a popular whalers´ target, and were hunted down to a few hundred animals in the Southern Hemisphere. The International Whaling Commission (IWC) implemented a moratorium on harvesting all species starting in 1986, and in 1994, declared Antarctica´s Southern Ocean a whale sanctuary. Now numbering over 10,000 in the Southern Hemisphere, humpbacks have shown incredible resilience, but their numbers still remain a fraction of their historic abundance. Recovery of regional populations varies, and the World Conservation Union (IUCN) lists the humpback as vulnerable.
Humpbacks also have two Northern Hemisphere populations that number around 11,500 in the North Atlantic and 6,000 in the North Pacific. Northern humpbacks are genetically differentiated from the Southern Hemisphere population, and have dark bellies, while the southern humpbacks have all-white bellies. They don´t interbreed, because while the southern populations are mating and calving in the warm tropical seas, northern populations are near the polar Arctic.
OUTLOOK
The International Whaling Commission (IWC) allows hunting by indigenous cultures but bans hunting of humpback whales. Japan has long engaged in IWC-sanctioned “scientific whaling" of minke and other whales, and plans to start hunting humpbacks in 2007. “We are all concerned about Japan´s plans to add this species to the scientific whaling quota", says Dr. Scott Baker, a renowned cetacean conservation biologist. Iceland also just started commercial whaling in 2006.
Some Asian countries allow the sale of whale meat from incidental bycatch, and a whale´s value of $100,000 provides incentive for illegal harvest. Baker and colleagues used DNA to show that the whale meat being sold in South Korean shops did not match that reported to the IWC. Illegal harvest and sale of whale meat is occurring.
Australia and New Zealand have petitioned the IWC to create a South Pacific Sanctuary adjoining the Southern Ocean Sanctuary where whaling would be illegal. Thus far, it has not been approved by IWC.

SOUTHERN HUMPBACK WHALE
INTRODUCTION
During the Australian winter, these ocean leviathans journey 3,100 miles north from their Antarctic feeding grounds to the warm tropical waters near Australia´s Whitsunday Islands. At the southern edge of the Great Barrier Reef, the 40-ton female humpbacks give birth to calves measuring 14 feet long and weighing over one ton. The Whitsundays´ sheltered bays keep the calves warm and safe from predators. During the next few months, the whales rest, sing, play and mate. The calves nurse, but the one thing the adult whales don´t do while in the tropical seas is eat. By winter´s end, adults are famished, and they head south. This life cycle is repeated throughout the Southern Hemisphere: one group migrates along the western coast of Australia, others to southern Africa and South America.
SIGHT UNSEEN
Underneath the blue Australian ocean, film crews captured the elegant rituals of southern humpbacks as they swim, sing, nurse, and play. A mother humpback whale supported her young calf from underneath, so it could breathe easier near the surface. Calves drink 130 gallons of milk a day! While baby grows fat, the mother starves for five months, her blubber stores depleting daily. Unlike the cold Antarctic waters, the seas here don´t grow rich with krill that humpbacks filer through their baleen plates. But she provides her calf with rich milk that contains some of the highest fat content of any mammal´s milk – 45 percent.

Now numbering over 10,000 in the Southern Hemisphere, humpbacks have shown incredible resilience, but their numbers still remain a fraction of their historic abundance. Recovery of regional populations varies, and the World Conservation Union (IUCN) lists the humpback as vulnerable.
Humpbacks also have two Northern Hemisphere populations that number around 11,500 in the North Atlantic and 6,000 in the North Pacific. Northern humpbacks are genetically differentiated from the Southern Hemisphere population, and have dark bellies, while the southern humpbacks have all-white bellies. They don´t interbreed, because while the southern populations are mating and calving in the warm tropical seas, northern populations are near the polar Arctic.
OUTLOOK
The International Whaling Commission (IWC) allows hunting by indigenous cultures but bans hunting of humpback whales. Japan has long engaged in IWC-sanctioned “scientific whaling" of minke and other whales, and plans to start hunting humpbacks in 2007. “We are all concerned about Japan´s plans to add this species to the scientific whaling quota", says Dr. Scott Baker, a renowned cetacean conservation biologist. Iceland also just started commercial whaling in 2006.
Some Asian countries allow the sale of whale meat from incidental bycatch, and a whale´s value of $100,000 provides incentive for illegal harvest. Baker and colleagues used DNA to show that the whale meat being sold in South Korean shops did not match that reported to the IWC. Illegal harvest and sale of whale meat is occurring.
Australia and New Zealand have petitioned the IWC to create a South Pacific Sanctuary adjoining the Southern Ocean Sanctuary where whaling would be illegal. Thus far, it has not been approved by IWC.

SOUTHERN HUMPBACK WHALE
INTRODUCTION
During the Australian winter, these ocean leviathans journey 3,100 miles north from their Antarctic feeding grounds to the warm tropical waters near Australia´s Whitsunday Islands. At the southern edge of the Great Barrier Reef, the 40-ton female humpbacks give birth to calves measuring 14 feet long and weighing over one ton. The Whitsundays´ sheltered bays keep the calves warm and safe from predators. During the next few months, the whales rest, sing, play and mate. The calves nurse, but the one thing the adult whales don´t do while in the tropical seas is eat. By winter´s end, adults are famished, and they head south. This life cycle is repeated throughout the Southern Hemisphere: one group migrates along the western coast of Australia, others to southern Africa and South America.
SIGHT UNSEEN
Underneath the blue Australian ocean, film crews captured the elegant rituals of southern humpbacks as they swim, sing, nurse, and play. A mother humpback whale supported her young calf from underneath, so it could breathe easier near the surface. Calves drink 130 gallons of milk a day! While baby grows fat, the mother starves for five months, her blubber stores depleting daily. Unlike the cold Antarctic waters, the seas here don´t grow rich with krill that humpbacks filer through their baleen plates. But she provides her calf with rich milk that contains some of the highest fat content of any mammal´s milk – 45 percent.
UNIQUE BEHAVIOR
Humpback males sing a unique melody, full of high-pitched chirps and whistles interspersed with deeper gurgles and moans. Each male repeats his song for hours, which likely plays a role in courtship. The song may change over time, with males singing a modified melody in consecutive years.
Whale-watching tours take advantage of the humpback´s playful and curious nature. They often approach boats and put on quite a show. As whales journey south along the eastern coast of Australia, many stop in sheltered Platypus Bay around Fraser Island – a World Heritage Site – where they display the charismatic behaviors loved by whale-watchers. The crystal blue waters give a perfect window to watch the whales twist, roll and swim upside down, emerging to breathe, slap their tails or pectoral fins on the water´s surface. Breaching whales jump nearly all the way out of the water. “Spyhopping" means their head emerges, and they peer at the surroundings with their large eyes.
STATUS/CONSERVATION
Commercial hunting in the 19th and 20th centuries decimated most whale species. Because they migrate close to shore and swim slowly, humpbacks became a popular whalers´ target, and were hunted down to a few hundred animals in the Southern Hemisphere. The International Whaling Commission (IWC) implemented a moratorium on harvesting all species starting in 1986, and in 1994, declared Antarctica´s Southern Ocean a whale sanctuary.
