(IME - 2016/2017 - 2 FASE) TEXTO 2 O HOMEM: AS VIAGENS Carlos Drummond de Andrade O homem, bicho da terra to pequeno Chateia-se na terra Lugar de muita misria e pouca diverso, Faz um foguete, uma cpsula, um mdulo Toca para a lua Desce cauteloso na lua Pisa na lua Planta bandeirola na lua Experimenta a lua Coloniza a lua Civiliza a lua Humaniza a lua. Lua humanizada: to igual terra. O homem chateia-se na lua. Vamos para marte - ordena a suas mquinas. Elas obedecem, o homem desce em marte Pisa em marte Experimenta Coloniza Civiliza Humaniza marte com engenho e arte. Marte humanizado, que lugar quadrado. Vamos a outra parte? Claro - diz o engenho Sofisticado e dcil. Vamos a vnus. O homem pe o p em vnus, V o visto - isto? Idem Idem Idem. O homem funde a cuca se no for a jpiter Proclamar justia junto com injustia Repetir a fossa Repetir o inquieto Repetitrio. Outros planetas restam para outras colnias. O espao todo vira terra-a-terra. O homem chega ao sol ou d uma volta S para tever? No-v que ele inventa Roupa insidervel de viver no sol. Pe o p e: Mas que chato o sol, falso touro Espanhol domado. Restam outros sistemas fora Do solar a col- Onizar. Ao acabarem todos S resta ao homem (estar equipado?) A dificlima dangerosssima viagem De si a si mesmo: Pr o p no cho Do seu corao Experimentar Colonizar Civilizar Humanizar O homem Descobrindo em suas prprias inexploradas entranhas A perene, insuspeitada alegria De con-viver. ANDRADE, Carlos Drummond. Nova reunio: 19 livros de poesia 3 ed. Rio de Janeiro: Jos Olympio, 1978, pp. 448-450. Assinale a alternativa em que os versos do Texto 2 e suas leituras abaixo fogem ideia de tdio e de colonizao do cosmos exteriorizadas no poema.

The standards and practices for this type of waste disposal vary greatly ranging from uncontrolled sites to highly specialised and controlled engineered landfills. The potential ___(17)___ of contaminants through landfill gas and leachate is largely dependent on landfill design, site conditions and the sophistication of the control measures in place, ___(18)___ landfill gas recovery and leachate collection and treatment systems. Modern engineered landfills use ___(19)___ barriers, with few relying on natural barriers, to line the bottom of a landfill and incorporate collection systems for both leachate and landfill gas. The purpose of these collection systems is to capture and treat leachate and landfill gas; __(20)____ preventing the migration of leachate into ground/surface water and the release of untreated landfill gases to the atmosphere. An un-engineered landfill would be considered an uncontrolled system due to the lack of environmental controls, potentially resulting in significant environmental exposure of contaminants. Because of widespread use of ENMs in a broad range of products, it is possible that some ENMs ___(21)___ through landfill gases; however this report will primarily focus on ENMs that may be present in landfill leachate, as this is considered to be the primary means by which ENMs could be transported___(22)___ a landfill.

(IME - 2016/2017 - 2 FASE) Texto 2 COULD EARTH BE FRIED BY A SUPERFLARE FROM THE SUN? Daniel Clery Solar flares on the sun frequently shower Earth with high-energy particles causing the Aurora Borealis and, occasionally, less-welcome disruptions to power networks and communications. But researchers say that there is a chancethough smallthat the sun could one day blast us with a solar flare thousands of times as powerful, potentially frying our atmosphere and obliterating life. Other stars occasionally produce such superflares, some up to 10,000 times the power of the largest solar flare ever detected. To see whether these are generated by the same process as happens on the sunthe breaking and reconnection of magnetic fieldsastronomers studied light from 100,000 stars using Chinas Guo Shouiing Telescope. As they report online in Nature Communications, superflares do seem to be produced by the same process, but they usually occur in stars with much stronger magnetic fields than the suns. Still, the researchers found that about 10% of the superflaring stars had magnetic fields similar to or weaker than the suns. From evidence in tree rings, the researchers say, it looks like Earth suffered small superflares10 to 100 times bigger than normalin 775 C.E. and 993 C.E. We can expect more, they conclude, once per millennium. (As for the chances of an Earth-frying flare, they dont say.)
