Problem: Write a multi-choice question for the following article: Article: Weighing too much can damage your health, and obesity is a growing problem for both kids and adults around the world. Sleep might be one answer to the problem. A new study has found that elementary school students who slept too little were more likely to gain pounds. Past studies have shown a link between sleeping less and weighing more, but scientists have had a tough time determining"which came first, the chicken or the egg,"says Julie C. Lumeng of the University of Michigan in Ann Arbor. In other words, it hasn't been clear whether kids who weigh too much have trouble sleeping, or whether sleeping less leads to weight gain. Both scenarios seemed equally possible. To get a better idea of which causes which, Lumeng and her colleagues interviewed the parents of 785 third graders from around the United States. The parents answered questions about how well their kids slept that year. Three years later, the parents answered the same questions. By sixth grade, 18 percent of kids involved in the study were obese. The scientists found no relationship between weight and the students' race or gender. It also didn't matter how strict their parents were, or whether they were boys or girls. Obesity struck all of these groups equally. Instead, sleep seemed to be the key factor. Over the 3 years of the study, the children averaged a healthy 9.5 hours of sleep a night. Some kids, however, slept a lot more -- or less -- than others. For the sixth graders, every hour of sleep above the 9.5-hour average was linked to a 20 percent lower risk of being obese. Sleep appeared doubly important for the third graders. Every extra hour of sleep they got was linked to a 40 percent drop in obesity.

Problem: Write a multi-choice question for the following article: Article: Birds in cities are damaging their health by trying to sing above the noise of urban life. New research shows that male birds are trying to compete against traffic and city sounds.They are now singing louder and at higher frequencies,which could harm their vocal cords .Some birds are choosing to sing at night instead of during the day.This makes them more open to attack and also creates stress and exhaustion. "The difference between urban and rural birdsong is becoming so big that the two groups could now be unable to communicate.This could lead to inbreeding and a weak gene poo1."said Dr Sue Anne Zollinger of the.University of St Andrews. According to Zollingar,a bird group with a small gene pool might adapt less quickly to new diseases and could be wiped out. A study of the dawn chorus found that birds in Berlin sang up to 14 decibels louder than those in the forest.The birds sang loudest on weekday mornings. "By trying to sing over the sound of the city,birds ale rising vocal injury,"said Zollinger."All this puts the same strain on a bird's vocal cords as when a human need to shout to be heard--except that the birds are doing it all day,every day,"she said. "Singing under such pressure means birds have less control over the sound they produce.Their songs may lose quality and become more rough--sounding."said Zollinger.This could make them appear less attractive to female birds. Mark Constantine,author of The Sound Approach to Birding,said:"Birdsong is important for our quality of life and has been proved to reduce our blood pressure.When we live in the centre of large,urban areas,we get stressed and it's extremely good to have birdsong around us.The impact on humans of birdsong is massive.It harms us,as well as the birds,if their songs become louder and simpler.

Problem: Write a multi-choice question for the following article: Article: We are going to see the ruins of Machu Picchu in the mountains of the Andes.Machu Picchu was forgotten for centuries but discovered in 1911 by Hiram Bingham, a professor from Yale.It is said to be one of the most beautiful ancient sites in the world. The Incas built the ancient civilization of Machu Picchu between the 12th century and the early 16th century.They spoke a language called Quechua but had no writing system at all.They kept records on various coloured strings with knots called quipu. The Incas proved to be wonderful architects.They built most of their buildings with huge stones but without using any cement to stick them together.However, the huge stones fit together so perfectly that you cannot force a sharp knife between two blocks.They also built bridges, tunnels through mountains and channels to bring water to their cities--just as the Romans did.The Incas turned the mountains into farmlands and planted corn and potatoes, and raised animals like llama and alpaca for food. Now Machu Piccu has become a major tourist site in Peru, attracting people from all over the world.

Problem: Write a multi-choice question for the following article: Article: People often say that the Englishman's home is his castle. They mean that the home is very important and personal to him.
