A partir da primeira década do século XXI, o Brasil retorna a ser receptor de imigrantes. Sobre esse tema, analise as informações abaixo.
1) A crise econômica internacional, iniciada em 2008, foi um dos motivos de o Brasil ter se tornado um polo de atração de imigrantes dos Estados Unidos, Espanha, Portugal, Itália, entre outros países. 2) Os locais de destino mais procurados pelos imigrantes são as pequenas cidades,principalmente as localizadas no interior dos estados brasileiros. 3) O Brasil passou a ser um destino preferencial dos haitianos, intensificado após o terremoto que aconteceu em 2010. Os haitianos entram no Brasil pelo Amazonas e Acre. 4) Os bolivianos, atraídos pelas oportunidades de empregos, entram clandestinamente no Brasil a partir da década de 1980, realizando trabalhos braçais, com elevada carga horária e má remuneração.

Ao longo da história do planeta, os principais agentes condicionantes do clima são:
Sobre esse tema, analise as afirmações a seguir.
1) Dentre os principais consequências desse processo, estão as perdas de nutrientes por lixiviação, a redução na capacidade de infiltração e de retenção de umidade do solo, a sedimentação e a deposição do material erodido nas zonas baixas do relevo. 2) A cobertura vegetal é importante para fornecer matéria orgânica e sombreamento ao solo, proporcionando, portanto, benefícios não apenas por evitar a erosão, como também por aumentar os organismos benéficos ao solo. 3) As vertentes em que a declividade é mais acentuada apresentam um predomínio da pedogênese sobre a morfogênese. Esse fato é marcante nas vertentes íngremes dos tabuleiros alagoanos. 4) A diminuição dos rendimentos nos cultivos é cada vez maior com a degradação do solo, devido à sobre-exploração, os altos índices de desmatamento, a eliminação da cobertura vegetal e o excesso de lavoura do solo. 5) Os solos submetidos a intenso voçorocamento são exatamente aqueles pouco desenvolvidos em que foi preservada a cobertura vegetal primitiva e densa.

Read the text below and answer the following question based on it.
More than half your body is not human
Human cells make up only 43% of the body's total cell count. The rest are microscopic colonists.
Understanding this hidden half of ourselves - our microbiome - is rapidly transforming understanding of diseases from allergy to Parkinson's.
No matter how well you wash, nearly every nook and cranny of your body is covered in microscopic creatures.
This includes bacteria, viruses, fungi and archaea (organisms originally misclassified as bacteria). The greatest concentration of this microscopic life is in the dark murky depths of our oxygen-deprived bowels.
The human genome - the full set of genetic instructions for a human being - is made up of 20,000 instructions called genes.
But add all the genes in our microbiome together and the figure comes out between two and 20 million microbial genes.
Prof Sarkis Mazmanian, a microbiologist from Caltech, argues: "We don't have just one genome, the genes of our microbiome present essentially a second genome which augment the activity of our own.
Science is rapidly uncovering the role the microbiome plays in digestion, regulating the immune system, protecting against disease and manufacturing vital vitamins.
It is a new way of thinking about the microbial world. To date, our relationship with microbes has largely been one of warfare.
Antibiotics and vaccines have been the weapons unleashed against the likes of smallpox, Mycobacterium tuberculosis or MRSA.
That's been a good thing and has saved large numbers of lives.
But some researchers are concerned that our assault on the bad guys has done untold damage to our "good bacteria".
Prof Knight has performed experiments on mice that were born in the most sanitised world imaginable.
He says: "We were able to show that if you take lean and obese humans and take their faeces and transplant the bacteria into mice you can make the mouse thinner or fatter depending on whose microbiome it got."
"This is pretty amazing right, but the question now is will this be translatable to humans"
This is the big hope for the field, that microbes could be a new form of medicine. It is known as using "bugs as drugs".

Soneto de fidelidade.
De tudo, ao meu amor serei atento
Antes, e com tal zelo, e sempre, e tanto
Que mesmo em face do maior encanto
Dele se encante mais meu pensamento.
Quero vivê-lo em cada vão momento
E em seu louvor hei de espalhar meu canto
E rir meu riso e derramar meu pranto
Ao seu pesar ou seu contentamento.
E assim, quando mais tarde me procure
Quem sabe a morte, angústia de quem vive
Quem sabe a solidão, fim de quem ama
Eu possa me dizer do amor (que tive):
Que não seja imortal, posto que é chama
Mas que seja infinito enquanto dure.
Vinicius de Moraes. Poesia completa e prosa. Rio de janeiro: Nova Aguilar, 1998, p. 289.
1) uma espécie de volta à poética cultivada pelos poetas do período literário do Parnasianismo. 2) a concepção de amor do eu-lírico, a qual foge da idealização do ‘amor para sempre e eterno’. 3) o jogo de oposição entre a fugacidade do amor – ‘posto que é chama’ – e sua infinitude, ‘enquanto dure’. 4) um certo afastamento das temáticas comuns à vida do cotidiano social das pessoas.
