Read the following article and select the best answer. Article: Getting close to active or erupting volcanoes can be dangerous. But for Michael Rampino, it's all in a day's work. Rampino is a volcanologist, a scientist who studies volcanoes and how they affect our planet. Rampino has been close to red-hot lava flows in Hawaii and explosive volcanoes in Indonesia. He knows when to get close to an active volcano and when to back away. Rampino wasn't always a volcanologist. He worked for NASA for seven years. He studied rocks until he began to research climate change and the effects that volcanoes have on climate. He became interested in the subject. "Once I started working with volcanoes," Rampino said, "I was _ ." Rampino is a professor at New York University. As part of his job, he travels to areas where volcanoes have been active. "Active" means they have erupted within the past few centuries and probably will erupt again. Rampino studies the deposits of ash and other materials from the eruptions. The ash may hold clues to what happened to the Earth in the distant past. It may also help scientists predict what could happen to Earth's climate in the future. Rampino doesn't work alone. He works with a team of scientists who use computers to stimulate the effects volcanoes have on Earth's atmosphere. Being a volcanologist may be hard work, but it's also fun. "It's cool traveling the world studying volcanoes," Rampino says. When he talks to students about his work, he tells them that his goal is "to understand the events that have shaped Earth's history." Question: To Rampino, being close to active volcanoes is _ . - adventurous but meaningful - scary but necessary - impossible and unnecessary - dangerous but urgent
adventurous but meaningful

Article: 136 Crestview Circle Dover, Connecticut November 16, 2015 Gander's Furniture Store Stamford, Connecticut, 09876 Dear Sir, I am writing about your November bill, which I am returning with this letter. I am not going to pay this bill. Last month I bought a table and four chairs for $65.50. They were sent to me on October 18. That night one leg of the table broke while my wife was putting our dinner on it. It fell on one of the chair, and that broke, too. Our $ 2.50 steak landed on the floor, and the dog ate it. I spoke to the salesmen who had sold me the table and the chairs. He told me to write you a letter. I wrote you on October 20, saying that I was not going to pay for the furniture. On October 21 some men came and took it back to the store. Please do something about your records. I do not want to receive another bill for the furniture which I returned. Yours truly Albertson Question: When Mr. Albertson was writing the letter he felt _ . - disappointed - angry. - worried. - calm.

Q: Read the following article and select the best answer. Article: If you are sitting down listening to what I'm going to say, stand up. Move your legs. Touch your toes, if you can. Do anything but sit. If you cut down on the time you spend sitting, you might live longer. New research shows that sitting less than three hours a day might extend your life by two years. Just the opposite, says Peter Katzmarzyk. He is a scientist at the University of Louisiana in the southern United States. He says that sitting is _ in our lives. "We sit while we're eating; we sit in the car; we sit while we watch TV. Many of us sit for many hours at work. " But, he adds, that does not make sitting good for us. The human body is designed to move. But modern lifestyles and office jobs rarely give us the chance to move around. Exercise is important. So is not sitting. "We can't throw away physical activity. It's extremely important. We have 60 years of research showing us that. Even if you exercise for 30 minutes a day, what goes on in the other 23-and-a-half hours a day is also very important." Mr. Katzmarzyk and his co-workers are part of a new generation of researchers studying how sitting all day affects length of life. This is a relatively new area of study--studies that have assessed the relationship between sitting and mortality or television viewing and mortality. Making uses of the few studies available to them, they found that cutting television time to less than two hours a day could add one-point four years to life. New desk designs are helping Change is already coming to some offices, especially in the design of desks. A "standing desk" lets people stand while they work. Another new design is called the "treadmill desk." A treadmill is an exercise machine that lets you walk in one place. That's one of the strategies that many companies are using now. Some companies may equip their employees with a "standing desk" or a "treadmill desk". Other companies may not buy one for everybody, but they'll have a bank of these desks where people can go for an hour a day and answer their emails or... Question: What might be the best title for the passage? - Take exercise, keep fit. - Change more, achieve greater. - Talk directly, improve relationship. - Sit less, live longer.
A: Sit less, live longer.

*Question*
Read the following article and select the best answer. Article: "Children who eat less salt and drink fewer sugar-sweetened soft drinks may significantly lower their risks of obesity," researchers recently reported in the journal Hypertension. "Sugar-sweetened soft drinks are a significant source of calorie intake in children," said Feng J. He, a researcher at St George's University of London, England. "It has been shown that sugar-sweetened soft drink consumption is related to obesity in young people." They wanted to know whether there is a link between salt intake and sugar-sweetened soft drink consumption. Dr He and colleagues analyzed data from a 1997 national survey of more than 2,000 people between 4 and 18 in Britain. "We found that children eating a lower-salt diet drank less fluid," said He. "From our research, we estimated that 1 gram of salt cut from their daily diet would reduce fluid intake by 100 grams per day." The researchers also found that children eating a lower-salt diet drank fewer sugar-sweetened soft drinks. From their research, they predicted that reducing salt intake by 1 gram each day would reduce sugar-sweetened soft drink consumption by 27 grams per day, after. "If children aged 4 to 18 cut their salt intake by half, there would be a decrease of about two sugar-sweetened soft drinks per week per child, so each child would decrease calorie intake by almost 250 kilocalories per week," Dr He said. In previous studies, researchers found that a low-salt diet lowers blood pressure in children, and prevents the development of high blood pressure later in life. "Both high blood pressure and obesity increase the risk of having strokes and heart attacks," Dr He said. Dr He recommends that parents check labels and choose low-salt food products. "Small reductions in the salt content of 10 to 20 percent cannot be detected by the human salt taste receptors and do not cause any technological or safety problems," Dr He said. Question: Which of the following statements would Dr He agree to? - The less salt people eat, the healthier people become. - Children should reduce fluid intake in their daily life. - No high-salt food products will be available in shops. - A low-salt diet may prevent both high blood pressure and obesity.
**Answer**
A low-salt diet may prevent both high blood pressure and obesity.
