Q: Read the following article and select the best answer. Article: While sweet treats can be hard to resist, the World Health Organization(WHO) has set new guidelines for people around the world. The guidelines, released on Wednesday, advise that both adults and children cut back on their sugar intake to stay healthy. In a statement, Francesco Branca, director of the WHO's nutrition department, said there is evidence that reducing daily sugar intake reduces the risk of being overweight and tooth decay . The guidelines do not apply to the sugars in fresh fruit and vegetables or those that are naturally present in milk. According to the WHO, there is no reported evidence of negative effects of consuming those sugars. Instead, the new guidelines focus on "added" or "free" sugars. These include sugars that are added to processed foods and drinks such as candy and soft drinks. Added sugars are sometimes described as " hidden" sugars because they exist in foods we might not think of as sweets, such as honey and ketchup . Health experts advise that consumers look at ingredients on food packages to help make better-informed decisions. The WHO recommends that people in the United States, Europe and other Western societies should cut their average sugar intake by about two-thirds, or down to just 10% of their overall calories. For developing countries, where dental care is less advanced, the WHO recommends that sugar intake be reduced to 5%. Scientist Kieran Clarke, of the University of Oxford, notes that for those people who can't shake their love for sweets, getting more exercise is a good solution. "If you get enough exercise, you can eat almost anything," she said "But it's very hard to avoid large amounts of sugar unless all you're eating is fruit and vegetables." Question: To what level should people in developing countries cut down their sugar intake, according to the WHO? - 10%. - 15%. - 5%. - 30%.
A: 5%.

Q: Read the following article and select the best answer. Article: It was only 5 o'clock in the morning. The house was quiet and Tim' s mother was still asleep. Only the sound of the big freezer broke the quiet. He'd dreamt of the cave last night. The purring of the freezer had been the sea. Tim pulled on a sweater and put some apples into his schoolbag. It was too early for breakfast. He' d eat after he' d been through the cave, sitting on the rocks and staring at the sea. He wished he had a proper pack. His schoolbag would have to do. What else? Sandwiches-but his mother might wake up if he started pulling out bread for sandwiches, she'd want to know why he had to leave so early. He settled for some biscuits, and left a note stuck to the table: Gone to Michael's. Back tonight, Tim. The sky was high and soft and light outside, though the sun still wasn't up. Even the highway up the hill was quiet as he made his way down the street. The wind from the sea was fresh and sweet. The sand hills still breathed heat from yesterday's sun, though the top of the sand was cool. He ran down to the beach impatiently, but there was no one, just dry sand dancing in the early wind and seabirds marching up and down watching the waves. The light changed suddenly. The first rays of sunlight stretched across the sea. The sun was pushing its way over the edge of the world. Over the first rocks, along to the point, Tim glanced back. The beach was still empty. The sun sailed higher in the sky. He could see the cave now, even darker in the morning light. The sand turned silver then dark gold as the water flowed away from it. He had to force himself to go closer. Why was it so much more mysterious now? But it would be silly to go back now after so much trouble. He needn't go in all the way... Question: In the story, Tim's mood changed from _ . - loneliness to craziness - anxiousness to excitement - eagerness to nervousness - helplessness to happiness
A: eagerness to nervousness

Q: Read the following article and select the best answer. Article: Today anyone will accept money in exchange for goods and services. People use money to buy food, furniture, books, bicycles and hundreds of other things we need or want. When they work, they usually get paid in money. Lots of the money today is made of paper. But people used to use all kinds of things as money. One of the first kinds of money was shells. Shells were not the only things used as money. In China, cloth and knives were used. In the Philippine Islands, rice was used as money for a long time. Some Africans once used elephant tusks, monkey tails, and salt as money. The first metal coins were made in China. They were round and had a square hole in the center. Different countries have used different metals and designs for their money. Later, countries began to make coins of gold and silver. But even gold and silver were inconvenient if you had to buy something expensive. Again the Chinese thought of a way to improve money. They began to use paper money. The first paper money looked more like a note from one person to another than the paper money used today. Money has had an interesting history, from the days of shell money until today. Question: What was first used as money? _ . - Elephants tusks - Cloth - Salt - Shells
A: Shells
