Consider the following excerpt: “Since
the 1970s, under the influence and
leadership of the US, the world has
tackled this problem with the use of
police forces, armies, and armaments.”
Mark the option which best describes the
use of some words in the excerpt.
Brazil must legalise drugs – its existing policy just destroys lives
For decades, guns and imprisonment have been the hallmarks of Brazil’s war against the drug trafficking. But the only way to beat the gangs is to stop creating criminals, says a top Brazilian judge
“The war raging in Rocinha, Latin America’s largest favela, has already been lost. Rooted in a dispute between gangs for control of drug trafficking, it has disrupted the daily life of the community in Rio de Janeiro since mid-September. With the sound of shots coming from all sides, schools and shops are constantly forced to close. Recently, a stray bullet killed a Spanish tourist. The war is not the only thing being lost.
For decades, Brazil has had the same drug policy approach. Police, weapons and numerous arrests. It does not take an expert to conclude the obvious: the strategy has failed. Drug trafficking and consumption have only increased. […]
In a case still before the Brazilian supreme court, I voted for decriminalising the possession of marijuana for private consumption. […]
Drugs are an issue that has a profound impact on the criminal justice system, and it is legitimate for the supreme court to participate in the public debate. So here are the reasons for my views.
First, drugs are bad and it is therefore the role of the state and society to discourage consumption, treat dependents and repress trafficking. The rationale behind legalisation is rooted in the belief that it will help in achieving these goals.
Second, the war on drugs has failed. Since the 1970s, under the influence and leadership of the US, the world has tackled this problem with the use of police forces, armies, and armaments. The tragic reality is that 40 years, billions of dollars, hundreds of thousands of prisoners and thousands of deaths later, things are worse. At least in countries like Brazil.
Third, as the American economist Milton Friedman argued, the only result of criminalisation is ensuring the trafficker’s monopoly.
With these points in mind, what would legalisation achieve?
In most countries in North America and Europe, the greatest concern of the authorities is users and the impact drugs have on their lives and on society. These are all important considerations. In Brazil, however, the principal focus must be ending the dominance drug dealers exercise over poor communities. Gangs have become the main political and economic power in thousands of modest neighbourhoods in Brazil. This scenario prevents a family of honest and hard-working people from educating their children away from the influence of criminal factions, who intimidate, co-opt and exercise an unfair advantage over any lawful activity. Crucially, this power of trafficking comes from illegality.
Another benefit of legalisation would be to prevent the mass incarceration of impoverished young people with no criminal record who are arrested for trafficking because they are caught in possession of negligible amounts of marijuana. A third of detainees in Brazil are imprisoned for drug trafficking. Once arrested, young prisoners will have to join one of the factions that control the penitentiaries – and on that day, they become dangerous.
[…]
We cannot be certain that a progressive and cautious policy of decriminalisation and legalisation will be successful. What we can affirm is that the existing policy of criminalisation has failed. We must take chances; otherwise, we risk simply accepting a terrible situation. As the Brazilian navigator Amyr Klink said: “The worst shipwreck is not setting off at all.”

DESENREDO
Adélia Prado
Grande admiração me causam os navios
e a letra de certas pessoas que esforço por imitar.
Dos meus, só eu conheço o mar.
Conto e reconto, eles dizem “anh”.
E continuam cercando o galinheiro de tela.
Falo da espuma, do tamanho cansativo das águas,
eles nem lembram que tem o Quênia,
nem de leve adivinham que estou pensando em Tanzânia.
Afainosos me mostram o lote: aqui vai ser a cozinha,
logo ali a horta de couve.
Não sei o que fazer com o litoral.
Fazia tarde bonita quando me inseri na janela, entre meus tios,
e vi o homem com a braguilha aberta,
o pé de rosa-doida enjerizado de rosas.
Horas e horas conversamos inconscientemente em português
como se fora esta a única língua do mundo.
Antes e depois da fé eu pergunto cadê os meus que se foram,
porque sou humana, com capricho tampo o restinho de molho na panela.
Saberemos viver uma vida melhor que esta,
quando mesmo chorando é tão bom estarmos juntos?
Sofrer não é em língua nenhuma.
Sofri e sofro em Minas Gerais e na beira do oceano.
Estarreço de estar viva. Ó luar do sertão,
ó matas que não preciso ver pra me perder,
ó cidades grandes, Estados do Brasil que amo como se os tivesse inventado.
Ser brasileiro me determina de modo emocionante
e isto, que posso chamar de destino, sem pecar,
descansa meu bem querer.
Tudo junto é inteligível demais e eu não suporto.
Valha-me noite que me cobre de sono.
O pensamento da morte não se acostuma comigo.
Estremecerei de susto até dormir.
E no entanto é tudo tão pequeno.
Para o desejo do meu coração
o mar é uma gota.

encontradas para o problema.
Sobre os Créditos de Carbono, informe
se é verdadeiro (V) ou falso (F) o que se
afirma a seguir e assinale a alternativa
com a sequência correta.
( ) Cada Crédito de Carbono é equivalente a
1T (uma tonelada) de CO² não emitida ou
retirada da atmosfera por um País.
( ) Os Créditos de Carbono foram criados,
em 1997, no Japão, quando houve a
assinatura do Protocolo de Kyoto pelos
países que se comprometeram a assinar
esse acordo.

O GPS (Global Positioning System)
desenvolvido pelo Departamento de
Defesa dos Estados Unidos causou
uma enorme transformação no que
tem sido a busca da humanidade por
localização instantânea, medição dos
terrenos em tempo real e visualização
de dados métricos do planeta terra
com imensa acurácia. A exemplo de
muitos outros artefatos desenvolvidos
com fins militares, o GPS penetrou a
vida cotidiana em todos os lugares do
mundo onde seja possível o uso dessa
ferramenta, como se tem tornado comum
nos diversos aplicativos para celulares.
O problema é que dados estratégicos
não são liberados para civis e, em
tempos de guerra ou conflito, os Estados
Unidos podem restringir ou mesmo
cortar o fornecimento das informações,
já que é o detentor da tecnologia. Em
vista disso, outros países têm buscado
desenvolver seus próprios sistemas de
posicionamento, mas, até o momento,
há um único sistema concorrente em
pleno funcionamento, desenvolvido pela
Rússia. Como esse sistema é nomeado?

No século XVII, o cientista inglês
Robert Hooke dedicou-se à observação
da estrutura da cortiça e constatou que
ela era formada por um grande número de
cavidades preenchidas com ar, as quais
chamou de células. Hoje, sabemos que as
células são preenchidas pelo citoplasma
e mantêm seu formato devido ao
citoesqueleto, que também é responsável
pelos movimentos celulares, formação
de pseudópodos e deslocamentos de
organelas. Considerando a participação
do citoesqueleto na mitose, é correto
afirmar que fármacos que interferem
na formação de microtúbulos, como a
colchicina, interrompem a mitose em
qual das seguintes fases?
Sobre a Estrutura Fundiária Brasileira, assinale a alternativa correta.
Uma floresta ripária submetida a

algumas embaúbas (espécies arbóreas

orifícios. A formação dessas estruturas
é uma resposta fisiológica adaptativa
comum em plantas submetidas ao
alagamento. Assinale a alternativa que
apresenta corretamente os nomes das
raízes e dos orifícios produzidos nessas
condições.

deparar com diferentes animais capazes
