Text I

Brazil's government claims its policies aren't to blame for the fires ravaging the Amazon rainforest. But scientists in Brazil and elsewhere disagree. Satellite data show the rise in blazes is linked to a recent rise in deforestation, which is at least partly the result of government policies, they argue. Most of the fires occur in municipalities with the highest rate of deforestation this year. Many are active for several days, burning with intense heat and producing tall, thick, smoke pillars—all indicators that trees are on fire, not overgrown pastures, crop residues, or roadside vegetation.

Text II

Precipitation decline and vegetation fires in the Amazon region associated with climate change and deforestation expose local communities to hazardous air quality that may lead to damages in human health such as diseases of the respiratory system. Since 2000, drought incidence over the Amazon has been observed at a higher frequency than during the last century, and the effects of the drier climate and fires on human health remain uncertain.

Remarks by the President Barack Obama on Osama Bin Laden (Part I)
THE PRESIDENT: Good evening. Tonight, I can report to the American people and to the world that the United States has conducted an operation that killed Osama bin Laden, the leader of al Qaeda, and a terrorist who’s responsible for the murder of thousands of innocent men, women, and children.
It was nearly 10 years ago that a bright September day was darkened by the worst attack on the American people in our history. The images of 9/11 are seared into our national memory hijacked planes cutting through a cloudless September sky; the Twin Towers collapsing to the ground; black smoke billowing up from the Pentagon; the wreckage of Flight 93 in Shanksville, Pennsylvania, where the actions of heroic citizens saved even more heartbreak and destruction.
And yet we know that the worst images are those that were unseen to the world. The empty seat at the dinner table. Children who were forced to grow up without their mother or their father. Parents who would never know the feeling of their child’s embrace. Nearly 3,000 citizens taken from us, leaving a gaping hole in our hearts.
On September 11, 2001, in our time of grief, the American people came together. We offered our neighbors a hand, and we offered the wounded our blood. We reaffirmed our ties to each other, and our love of community and country. On that day, no matter where we came from, what God we prayed to, or what race or ethnicity we were, we were united as one American family.
We were also united in our resolve to protect our nation and to bring those who committed this vicious attack to justice. We quickly learned that the 9/11 attacks were carried out by al Qaeda an organization headed by Osama bin Laden, which had openly declared war on the United States and was committed to killing innocents in our country and around the globe. And so we went to war against al Qaeda to protect our citizens, our friends, and our allies.

FOR CATS, A BIG GULP WITH A TOUCH OF THE TONGUE

  It has taken four highly qualified engineers and a bunch of integral equations to figure it out, but we now know how cats drink. The answer is: very elegantly, and not at all the way you might suppose. Cats lap water so fast that the human eye cannot follow what is happening, which is why the trick had apparently escaped attention until now. With the use of high-speed photography, the neatness of the feline solution has been captured. The act of drinking may seem like no big deal for anyone who can fully close his mouth to create suction, as people can. But the various species that cannot do so — and that includes most adult carnivores — must resort to some other mechanism. Dog owners are familiar with the unseemly lapping noises that ensue when their thirsty pet meets a bowl of water. The dog is thrusting its tongue into the water, forming a crude cup with it and hauling the liquid back into the muzzle.

  Cats, both big and little, are so much classier, according to new research by Pedro M. Reis and Roman Stocker of the Massachusetts Institute of Technology, joined by Sunghwan Jung of the Virginia Polytechnic Institute and Jeffrey M. Aristoff of Princeton. Writing in the Thursday issue of Science, the four engineers report that the cat’s lapping method depends on its instinctive ability to calculate the balance between opposing gravitational and inertial forces. What happens is that the cat darts its tongue, curving the upper side downward so that the tip lightly touches the surface of the water.

  The tongue is then pulled upward at high speed, drawing a column of water behind it. Just at the moment that gravity finally overcomes the rush of the water and starts to pull the column down — snap! The cat’s jaws have closed over the jet of water and swallowed it. The cat laps four times a second — too fast for the human eye to see anything but a blur — and its tongue moves at a speed of one meter per second. Being engineers, the cat-lapping team next tested its findings with a machine that mimicked a cat’s tongue, using a glass disk at the end of a piston to serve as the tip. After calculating things like the Froude number and the aspect ratio, they were able to figure out how fast a cat should lap to get the greatest amount of water into its mouth. The cats, it turns out, were way ahead of them — they lap at just that speed. To the scientific mind, the next obvious question is whether bigger cats should lap at different speeds.
