But scientists have warned that as the hole closes up in the next few decades, temperatures on the continent could rise by around 3oC on average, with melting ice contributing to a global sea level increase of up to 1.4 metres. In the past decades the western Antarctic has seen rapid ice loss as the world has warmed, but the other parts of the continent have, _ , been cooling, resulting in a 10% increase in ice in the seas around the region. This is because the hole in the ozone layer has increased cold winds in Antarctica, making much of the continent surface colder than usual. But now that the gasses that cause the ozone hole have been banned, scientists expect the hole to repair itself within the next 50 to 60 years. By then the cooling effect will have faded out and the Antarctic will face the full impact of global warming. This means an increase in average air temperatures of around 3OC and a reduction in sea ice by around a third. The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who monitors Antarctica ice sheets, said, "The ice sheets in Antarctica are hundreds of metres thick. But once warm ocean waters start flowing underneath, the ice will begin thinning and could break up very quickly. "Thinning ice sheets cause ice to break away from the continent and to melt even faster. Escaping ice from western Antarctica has already resulted in a 10% rise in global sea level in recent decades. Johnson believes that international action to reduce global warming is required immediately or it may be too late. "Everything is connected - Antarctica may be a long way away but it is an important part of the Earth's system," said Johnson. "It contains 90% of the world's ice, 70% of the world's fresh water and that is enough, if it melts completely, to raise sea levels by 63 metres." Even in a worse-case situation scientists don't expect the ice to entirely... Question: What is the effect of the hole in the ozone layer on Antarctica? Options: A: It is making much of the continent colder. B: It is causing the ice to melt faster. C: It is making the effects of global warming in the region worse. D: It is reducing the amount of water in Antarctica.

Read the article and select the best answer. Article: Not very long ago, the question would have seemed absurd. Now it is on the lips of respected scientists; MPs are beginning to talk of "a war on sugar", and even England's chief medical officer has said sugar may have to be, like the old enemy tobacco, taxed in order to protect the nation's health. There came a time in the evolution of public attitudes to smoking, when the doctors had been shouting for long enough that the public was broadly aware of the risks and the only question left,for Government was: what should we do about it? Some believe we are now at the same point in our attitudes to sugar. Others - largely but not only representatives of the food and drink industry - say the entire debate has been skewed, by those who spread stories deliberately to make people nervous. More or less everyone agrees that eating too much sugar is bad for you. There is also no doubt obesity is a growing problem which is putting a significant, avoidable burden on the NHS by increasing the rates of diabetes, heart disease and other long-term conditions. But to what extent is sugar - rather than saturated fats, or salt, carbohydrates or proteins, or any of the other devils of modem diets - the cause of obesity and how much should we worry about it? Yesterday, hopes of achieving anything resembling clarity from the World Health Organisation (WHO) were confused once again, which, widely expected to reduce the recommended sugar intake by a half in new draft guidance, instead said it would continue to recommend that sugar make up no more than 10 per cent of the energy we consume, while adding that cutting this to five per cent would have "additional benefits". The decision will now go out to public consultation. Simon Capewell, professor of the University of Liverpool, said that he suspected "dirty work" on the part of food and drinks companies might lie behind the WHO's less than resounding message. "The food industry say Govemment has no business interfering in families, we must...

Ques:Read the article and select the best answer. Article: While children are dogs---loyal and affectionate --teenagers are cats. It's so easy to be a dog owner. You feed it, train it, and boss it around. It puts its head on your knee and gazes at you as if you were a Rembrandt painting. It bounds indoors with enthusiasm when you call it. Then around age 13, your adoring little puppy turns into a big old cat. When you tell it to come inside, it looks amazed, as if wondering who died and made you emperor. Instead of dogging your doorsteps, it disappears. You won't see it again until it gets hungry--then it pauses on its sprint through the kitchen long enough to turn its nose up at whatever you're serving. when you reach out to ruffle its head, in that old affectionate gesture, it twists away from you, then gives you a blank stare, as if trying to remember where it has seen you before. You, not realizing that the dog is now a cat, think something must be desperately wrong with it. It seems so antisocial, so distant, sort of depressed. It won't go on family outings. Since you are the one who raised it, taught it to fetch and stay and sit on command, you assume that you did something wrong. Flooded with guilt and fear, you redouble your efforts to make your pet behave. Only now you're dealing with a cat, so everything that worked before now produces the opposite of the desired result. Call it, and it runs away. Tell it to sit, and it jumps on the counter. The more you go toward it, wringing your hands, the more it moves away. Put a dish of food near the door, and let it come to you. But remember that a cat needs your help and your affection too. Sit still, and it will come, seeking that warm, comforting lap it has not entirely forgotten. Be there to open the door for it. One day your grown-up child will walk into the kitchen, give you a big kiss and say, "You've been on your feet all day. Let me get those dishes for you. " Then you'll realize your cat is a dog again. Question: When you call a dog, how will it probably react to you? Options: A: excitedly B: indifferently C: angrily D: calmly
