Então, reduzir a desigualdade por meio da redistribuição prejudica o crescimento econômico? Não, segundo dois estudos marcantes feitos por economistas do FMI (Fundo Monetário Internacional), que dificilmente é uma organização de esquerda. O primeiro estudo examinou as relações históricas entre desigualdade e crescimento e descobriu que os países com desigualdade de renda relativamente baixa "têm mais êxito em alcançar um crescimento econômico sustentado, em oposição a surtos ocasionais". O segundo, divulgado no mês passado, analisou diretamente o efeito da redistribuição de renda e concluiu que "a redistribuição parece geralmente benigna em termos de seu impacto sobre o crescimento.

                                          FIGHTING FAT IN THE DESERT 

                                                  By Rod Nordland 

1 Qatari officials have been racking their brains to find a way to address their country's epidemic of obesity. They have built sports facilities, parks, and a splendid hillside road in the capital, with a seaside promenade and parkour stations; hosted fun runs with hefty cash prizes; set up free body mass index and blood pressure monitoring stations. Anything money can buy to draw their citizens — said to be first-richest in the world and sixth-fattest — out of a sedentary lifestyle, they seem to have bought.

2 The only thing is, even Qatar's great wealth has not been able to do anything about the weather, and in a country where highs top 40 degrees Celsius (104 Fahrenheit) for a large part of the year, getting anyone to go out and walk, let alone do outdoor sports, is a lost cause. About the only pedestrians in the summer, when temperatures are even higher, are expatriates. 

3 Now the sports health authorities have introduced a new program that aims to reach Qataris where they live, or at least where they shop — the climate-controlled shopping mall. Four of the emirate's major malls are participating in the program, called “Step Into Health: Walk More, Walk the Mall," posting maps and walking routes, along with information about how many calories could be burned in the process. The malls are also opening their halls two hours before and after shopping hours, for those who want their exercise free of consumerism.

4 “Mall walking is the perfect workout, alongside controlled temperatures; it provides a clean and safe environment to exercise," a promotional brochure for “Step Into Health" reads. The mall walk program is part of a broader effort to encourage Qataris “to walk 10,000 steps and more a day in a noncompetitive, recreational and social way." The organizers hasten to reassure people that mall walking need not be strenuous. “Unlike most community exercise programs, Step Into Health is not about working up a sweat," they say. The walking routes and speeds they have outlined are not likely to do that. 

5 Obesity is a touchy subject in the emirate. Data from the International Association for the Study of Obesity shows that Qatar has the highest obesity rates in the Middle East. About 34 percent of Qatar's men and 45 percent of its women are obese, defined as a body mass index of more than 30. 

6 Those figures, however, only begin to tell the tale. They are based on the emirate's total population of about 1.9 million, but most of those are migrant workers. Qatari citizens number only about 250,000. Since most of the migrant workers are construction and other manual laborers, obesity rates among citizens are likely to be far higher than overall figures suggest. 

7 The first mall walk two weeks ago was pronounced a big success by the government-controlled news media, with some 1,000 people showing up to take part — encouraged by handouts of pedometers (free to anyone who registers for Step Into Health), and free raffles of iPhones, laptops and other Qatari-size baubles. 

8 After that initial outpouring of interest, however, there was relatively little follow-up — a common phenomenon, as every gym manager knows. Soon after, the participating malls were nearly as empty in those shopping-free hours as ever.

                                             FLORIDA HURRICANES

1 Before Hurricane Sandy tore through New York and New Jersey, it stopped in Florida. Huge waves covered beaches, swept over Fort Lauderdale's concrete sea wall and spilled onto A1A, Florida's coastal highway. A month later another series of violent storms hit south Florida, severely eroding Fort Lauderdale's beaches and a section of A1A. Workers are building a new sea wall, mending the highway and adding a couple of pedestrian bridges. Beach erosion forced Fort Lauderdale to buy sand from an inland mine in central Florida; the mine's soft, white sand stands out against the darker, grittier native variety.

2 Hurricanes and storms are nothing new for Florida. But as the oceans warm, hurricanes are growing more intense. To make matters worse, this is happening against a backdrop of sharply rising sea levels, turning what has been a seasonal annoyance into an existential threat.

3 For around 2,000 years sea levels remained relatively constant. Between 1880 and 2011, however, they rose by an average of 0.07 inches (1.8mm) a year, and between 1993 and 2011 the average was between 0.11 and 0.13 inches a year. In 2007 the Intergovernmental Panel on Climate Change (IPCC) forecast that seas could rise by as much as 23 inches by 2100, though since then many scientists have called that forecast conservative. Seas are also expected to warm up, which may make hurricanes and tropical storms more intense.

4 Even as seas have risen over the past century, Americans have rushed to build homes near the beach. Storms that lash the modern American coastline cause more economic damage than their predecessors because there is more to destroy. The Great Miami Hurricane of 1926, a Category 4 storm, caused $1 billion-worth of damage in current dollars. Were it to strike today the insured losses would be $125 billion, reckons Air Worldwide, a catastrophe-modelling firm. In 1992 Hurricane Andrew, a Category 5 storm, caused $23 billion in damage; today it would be twice that

5 Most Floridians live in coastal counties. Buildings cluster on low ground; more people than in any other state live on land less than four feet (1.2 metres) above the high-tide line. Florida's limestone bedrock makes it easy for salt water from surging seas to contaminate its freshwater aquifers. And it relies heavily on canals for flood control, which a sea-level rise of just six inches would devastate.

Para a composição do texto, o autor recorre ao emprego reiterado do recurso da antítese, como se pode verificar nos pares de palavras “princípio" e “fim", e “nascimento" e “morte". Examine os seguintes pares de palavras, considerando a relação de sentido que eles têm no contexto.

I "campa" e “berço";
II “galante" e "novo";
III “introito" e “cabo";
IV “rijos" e “prósperos".

É correto afirmar que constituem antíteses apenas os pares

Argumento (Paulinho da Viola)

Tá legal
Eu aceito o argumento
Mas não me altere o samba tanto assim
Olha que a rapaziada está sentindo a falta
De um cavaco, de um pandeiro
Ou de um tamborim.

Sem preconceito
Ou mania de passado
Sem querer ficar do lado
De quem não quer navegar
Faça como um velho marinheiro
Que durante o nevoeiro
Leva o barco devagar.

Ao empregar, na letra da canção, o verbo “navegar" em sentido metafórico e desdobrar esse sentido nos versos seguintes, o compositor recorre ao seguinte recurso expressivo:

      Eram tempos menos duros aqueles vividos na casa de Tia Vicentina, em Madureira, subúrbio do Rio, onde Paulinho da Viola podia traçar, sem cerimônia, um prato de feijoada - comilança que deu até samba, "No Pagode do Vavá". Mas como não é dado a saudades (lembre-se: é o passado que vive nele, não o contrário), Paulinho aceitou de bom grado a sugestão para que o jantar ocorresse em um dos mais requintados italianos do Rio. A escolha pela alta gastronomia tem seu preço. Assim que o sambista chega à mesa redonda ao lado da porta da cozinha, forma-se um círculo de garçons, com o maître à frente. [...]
      Paulinho conta que cresceu comendo o trivial. Seu pai viveu 88 anos à base de arroz, feijão, bife e batata frita. De vez em quando, feijoada. Massa, também. "Mas nada muito sofisticado."
      Com exceção de algumas dores de coluna, aos 70 anos, goza de plena saúde. O músico credita sua boa forma ao estilo de vida, como se sabe, não dado a exageros e grandes ansiedades.

Em 09 de agosto de 1945, uma bomba atômica foi detonada sobre a cidade japonesa de Nagasaki. A bomba explodiu a 500 m de altura acima do ponto que ficaria conhecido como “marco zero”.

                        

No filme Wolverine Imortal, há uma sequência de imagens na qual o herói, acompanhado do militar japonês Yashida, se encontrava a 1 km do marco zero e a 50 m de um poço. No momento da explosão, os dois correm e se refugiam no poço, chegando nesse local no momento exato em que uma nuvem de poeira e material radioativo, provocada pela explosão, passa por eles.

A figura a seguir mostra as posições do “marco zero”, da explosão da bomba, do poço e dos personagens do filme no momento da explosão da bomba.

                        

Se os ventos provocados pela explosão foram de 800 km/h e adotando a aproximação √5 ≅ 2,24 , os personagens correram até o poço, em linha reta, com uma velocidade média, em km/h, de aproximadamente
