Problem: Given the question: Write a multi-choice question for the following article: Article: Here's an unusual story: a diamond ring was recently found in an egg. The magician , Liu Qian, discovered it, in front of an audience of millions at CCTV's Spring Festival Gala. Liu's magic tricks have made the centuries old art of magic fashionable once again, and made him the hottest magician in China. As a _ young magician from Taiwan, Liu is popular worldwide for his magic shows. Countries he has performed in include the United States, Japan, South Korea and the UK. Witnessing something impossible happen right before your eyes is the root of people's love for magic. Liu is known for his interaction with his audiences. He has a unique understanding of showmanship . "It is actually thinking, rather than one's manipulation skills, that is more important to achieving a successful magic show. We think carefully about how to design the shows creatively, to make them appear more intriguing ,"Liu said. Liu Qian's success dates back to his childhood. Born in 1976 in Taiwan, he found himself attracted to a magic toy in a shop when he was seven years old. At the age of 12, he won Taiwan's Youth Magic Contest, which was judged by the great American magician, David Copperfield. Yet, Liu never planned on becoming a professional magician. He studied Japanese literature at university and only hoped to be an amateur magician in his spare time. However, his failure to find a decent job after graduation pushed him towards magic as a career. To refine his performing skills, he has performed on streets, roads and fields, for pedestrians , policemen and farmers. "Street shows are the biggest challenge for us magicians. We have to deal with unexpected situations and tough crowds," Liu said.

input question: Write a multi-choice question for the following article: Article: Smart Exercise Doctors are starting to find more and more information that suggests a connection between exercise and brain development. Judy Cameron, a scientist at Oregon Health and prefix = st1 /ScienceUniversity, studies brain development. According to her research, it seems that exercise can make blood vessels, including those in the brain, stronger and more fully developed. Dr. Cameron claims this allows people who exercise to concentrate better. As she says: "While we already know that exercise is good for the heart, exercise can literally cause physical changes in the brain." The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active. With babies, even a little movement can show big results. Margaret Barnes, a pediatrician , believes in the importance of exercise. She thinks that many learning disabilities that children have in elementary school or high school can be traced back to a lack of movement as babies. "Babies need movement that stimulates their five senses. They need to establish a connection between motion and memory. In this way, as they get older, children will begin to associate physical activity with higher learning," says Margaret. Older people can beef uptheir brains as well.CornellUniversitystudied a group of seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase of up to 40 percent after exercising just three hours a week. The exercise does not have to be very difficult, but it does have to increase the heart rate. Also, just like the motion for infants, exercise for older people should involve some complexity. Learning some new skills or motions helps to open up memory paths in the brain that may not have been used for a long time. For most people, any type of physical activity that increases the heart rate is helpful. The main goal is to increase the brain's flow of...???
output answer: Question: Margaret Barnes thinks that a lack of movement in infancy canOptions:A lead to learning troubles later.B cause physical disabilities later.C stimulate the five senses.D bring about changes in the brain.Answer:A

Write a multi-choice question for the following article: Article: A volcanic eruption in Iceland has sent ash across northern Europe. Airlines have stopped or changed the flights across the Atlantic Ocean, leaving hundreds of passengers stuck in airports. Grimsvotn is one of the largest and most active volcanoes in Europe. What makes Grimsvotn different is that it lies under a huge glacier of ice up to 12 metres thick. The hot volcano heats up the ice above it, which then forms a layer of water between glacier and the volcano, keeping it stable. As the water flows out from under the glacier, the pressure lifts. The lava from the volcano then comes up to the surface. This is exactly what is happening today. Now airlines have to make changes to their flights so as not to fly through the clouds of volcanic ash. According to KLM, one of Europe's biggest airlines, airplanes cannot go under the cloud or over it. Going through the cloud can result in ash getting stuck in the airplane's engines, causing damage to the plane. The eruption has also caused problems for animals in Iceland. The volcano left ash and sharp, glass-like rocks all over the countryside. Farmers are keeping their animals inside to stop them eating ash-covered grass or the sharp objects.

Answer: Question: What makes Grimsvotn different from other volcanoes?Options:A It is under the sea.B Its lava affects the airlines.C It is the largest volcano.D It is below ice.Answer:D

Please answer this: Write a multi-choice question for the following article: Article: Paying a higher price than usual for a ticket to see a film in 3D is the annoyance of many a cinema-goer's life. But there may be a benefit to doing so, as a study has found that 3D films exercise the brain and improve short-term functioning in a similar way to brain-training tests. The research found that people who watched a movie in 3D improved cognitive skills, compared to those who watched it in 2D. The research was led by neuroscientist Dr Patrick Fagan from Goldsmiths University in London. More than 100 people took part in the experiment, where participants watched Disney filmBig Hero 6in either standard format or RealD 3D. They also carried out a brain-training-style test before and after seeing a section from the film. The test covered memory, reaction times and cognitive function and the results were compared later. According to the research, which was carried out in partnership with science group Thrill Laboratory, participants experienced a 23 percent increase in cognitive processing, as well as an 11 percent increase in reaction times. Dr Fagan said that the results showed enough of an improvement in brain function to suggest that 3D could play a part in improving brain power in the future. "These findings are more significant than you might think," he said. "It is a fact that people are living longer and there is a noticeable decline in cognitive brain function in old age which can worsen future quality of life. There has never been a better time to look at ways to improve brain function. The initial results of this study show that 3D films may potentially play a role in slowing this decline." A second part of the experiment involved those watching the film being fitted with headsets that scanned brain activity and this too showed heightened activity when watching 3D. According to the results, participants were seven percent more engaged with what they were watching, adding to argument that 3D movies are more like watching real-life--something Professor Brendan Walker from Thrill Laboratory...
