Read the following article and select the best answer. Article: Many children first learn the value of money by receiving an allowance. The purpose is to let children learn from experience at an age when financial mistakes are not very costly. The amount of money that parents give to their children to spend as they wish differs from family to family. Timing is another consideration. Some children get a weekly allowance. Others get a monthly allowance. In any case, parents should make clear what, if anything, the child is expected to pay for with the money. At first, young children may spend all of their allowance soon after they receive it. If they do this, they will learn the hard way that spending must be done within a budget. Parents are usually advised not to offer more money until the next allowance. The object is to show young people that a budget demands choices between spending and saving. Older children may be responsible enough to save money for larger costs, like clothing or electronics. Allowances give children a chance to experience the things they can do with money. They can share it in the form of gifts or giving to a good cause. They can spend it by buying things they want. Or they can save and maybe even invest it. Saving helps children understand that costly goals require sacrifice: you have to cut costs and plan for the future. Requiring children to save part of their allowance can also open the door to future saving and investing. Many banks offer services to help children and teenagers learn about personal finance. A savings account is an excellent way to learn about the power of compound interest . That may not seem like a lot. But over time it adds up. Question: The author intends to _ . - make parents aware of the children's allowances - show the methods of investing - give advice on how to save money - introduce the advantages of allowances
make parents aware of the children's allowances

Some dolphins made it. About 24 died. For 35 dolphins in danger there was only one chance for survival--to be sent to the Marine Mammals Care Centre. The dolphins were placed in a water pool where they have been given care _ by hundreds of volunteers who signed up for four-hour shifts . By the second week in April, only 11 of the original 35 were still alive. Each year thousands of dolphins, the lovely marine mammals, are found beached or stranded along coastlines around the world. They can't get back to the sea and will die if they don't get help, according to the Whale and Dolphin Conservation Society's website. Nobody knows what caused the dolphins to strand themselves, but the US Navy and marine wildlife experts are investigating whether the dolphin stranding was caused by sonar exercises of ships. And some scientists suggest disease, or human interference . The reason for stranding isn't completely understood. In the pool, volunteers hold the dolphins and keep their blowholes out of the water so they can breathe. A vet injects the mammals with vitamin E to help with muscle cramping . Unable to eat on their own, they are fitted with a feeding tube to get them the needed nutrition. "Today we made the first steps in getting them to eat dead fish and to eat them out of our hands," Banick said. It's a race against time and feeding times must be strictly kept to. Question: How many dolphins had died by the second week in April? - 11. - 24. - 35. - 46

Q: Read the following article and select the best answer. Article: Twenty years are just a blink in time. But 20 years is also long enough for a man to grow up. It is always painful. For Andre Agassi, maturing in the spotlight of international tennis competition was even harder. On September 3, the American tennis player said a tearful goodbye to his 21-year career after a third-round defeat in the US Open. The 36-year-old tried his best, but was unable to keep up with German Benjamin Becker, _ years his _ "The scoreboard said I lost today, but what the scoreboard doesn't say is what I've found," Agassi said to the fans. "I have found inspiration and you willed me to succeed." It was an emotional speech at the end of a long career. Agassi hated tennis as a teenager as much as he loves it now. His father made him play when he was a child. He got bored, and became a rebel . The strict training that his father pushed upon him got in the way of his wild lifestyle. He grew hair long, wore colourful clothes and spat at a judge. Over the years, he has made bad jokes during news conferences Asked what he would say to his 17-year-old self, Agassi answered, "I would say, I understand you a lot more than I want to be you." The turning point in Agassi's career came in 1992 when he unexpectedly won his first Grand Slam at Wimbledon. It was the first time Agassi understood what real champions finally understand: winning is a test of courage and not just power, it's a marathon, not a sprint . And what a marathon Agassi was about to begin. He cut his long hair, got fitter and tightened up emotionally. On the court, he was ranked No. 1 for almost two years. His lowest point came in 1997 when his ranking dropped to No. 141. He didn't quit though. "I knew that I would try to get the most out of myself every day from that day forward. That was my promise," he said. "That never stopped." Question: The passage implies_. - after 1997 Agassi began to take up marathon besides tennis - Agassi began to play tennis before he was fifteen - Agassi decided to quit his sports career - the reason why Agassi lost his last competition was that he was lack of courage and power
A: Agassi began to play tennis before he was fifteen

Read the following article and select the best answer. Article: What do the common cold, the flu, and AIDS have in common? They are all diseases caused by viruses, tiny microorganisms that can pass from person to person. It is no wonder that when most people think about viruses, finding ways to _ them is what is on people's minds. Not everyone runs from the tiny disease carriers, though. In Cambridge, Massachusetts, scientists have discovered that some viruses can be helpful in an unusual way. They are putting viruses to work, teaching them of the world's smallest rechargeable batteries. Viruses and batteries may seem like an unusual pair, but they are not so strange for engineer Angela Belcher, who first came up with idea. At the Massachusetts Institute of Technology in Cambridge, she and her team bring together different areas of science in new ways. In the case of the virus-built batteries, the scientists combine what they know about biology, technology and production techniques. Belcher's team includes Paula Hammond, who helps put together the tiny batteries, and Yet-Ming Chiang, an expert on how to store energy in the form of a battery. Many batteries are already pretty small. However, every year, new electronic devices like personal music players or cellphones get smaller than the year before. As these devices become smaller, ordinary batteries won't be small enough to fit inside. The ideal battery will store a lot more energy in a smaller package than ordinary batteries. Right now, Belcher's model battery, a metallic disk completely built by viruses, looks like a regular watch battery. But inside, its parts are very small--- so tiny that you can only see them with a powerful microscope. How small are these battery parts? To get some idea of the size, pluck one hair from your head. Place your hair on a piece of white paper and try to see how wide your hair is--- pretty thin, right? Although the width of each person's hair is a bit different, you could probably fit about 10 of these virus--- built battery parts, side by side, across one hair. These... Question: What is the passage mainly about? - Diseases caused by viruses. - An engineer called Angela Belcher. - Batteries built by viruses. - Rechargeable batteries.
