Scientists from Britain and Poland took cells from his nose, transplanted them into his back and re-grew his spinal cord . Now he can walk and even drive a car. The doctors were delighted but said it was the first step in a long journey. The breakthrough came after 40 years of research by Professor Geoff Raisman, who found that cells had the possibility to repair damage to nasal nerves, the only part of the nervous system that constantly re-grows. "The idea was to take something from an area where the nervous system can repair itself and put it into an area that doesn't repair itself," Professor Raisman said. Polish doctors injected the nasal cells into Mr Fidyka's spinal cord above the injury and used some nerves from his ankle to form a bridge across the damaged tissue. The nasal cells appear to have caused the spinal nerves to repair themselves. Professor Raisman achieved this with rats in the late 1990's, but this is his greatest success. "I think the moment of discovery for me was Christmas in 1997 when I first saw a rat, which couldn't control its hand, put its hand out to me. That was an exciting moment, because I realized then that my belief that the nervous system could be repaired was true." Doctors chose the easiest case for their first attempt--it might not work for others. But there is a real sense of hope that an idea once thought impossible has been realized. David Nicholls, who helped provide money for the breakthrough, said information about the breakthrough would be made available to researchers across the globe. "What you've got to understand is that for three million paralyzed people in the world today, the world looks a totally brighter place than it did yesterday," he said. Question: How did the operation work for Darek Fidyka? Options: A: The nervous system in the spinal nerves can repair itself. B: The nerves from his ankle cured the patient of the injury. C: The nasal cells re-produced and spread over very quickly. D: The nasal cells helped the spinal nerves to repair themselves.

Baymax, the plus-sized white robot, asks the question each time he detects his patient's pain. Considering that he is hardly like a typical Marvel superhero, how could this robotic caregiver from Big Hero 6 have stolen viewers' hearts and taken home this year's best animation Oscar? Set in fictional San Fransokyo, the film follows Hiro, a 14-year-old robotics genius . After his brother dies, he goes on a journey to save his city from an evil masked man with his brother's invention, Baymax. Baymax was named "Disney's most straightforwardly adorable character" in years by The Telegraph. He has a pure white pear-shaped body and stumpy elephant legs. And his eyes -just two black dots with a line through them - can blink quickly or slowly. Baymax's physical appearance "works with his personality because he's purely good and naive ," co-director Don Hall told The Hollywood Reporter. Sometimes Baymax is awkward. Moving in tight spaces gets challenging with his potbelly . And when his batteries run low, he behaves like an amusing drunk. "This means that he is not at all intimidating and is easy to like," commented The Straits Times in Singapore. Baymax is a comforting friend, the kind that perhaps everyone needs. After he diagnoses Hiro with feeling sorrow, he says: "Physical comfort helps too," and pulls Hiro into a hug. He pats his head, saying: "There, there." The team's car crashes into the water at one point, and they have to walk shivering back home. Baymax notices that everyone's body temperatures are low, so he turns on his internal heaters. Everyone cuddles up with him. "This is like spooning with a warm marshmallow ," says Fred, one of the characters. One minute, he is used as a bouncy castle , and the next he transforms into a superhero. To fight against the villain, Hiro upgrades Baymax so that the robot can attack and fly. The robot has a hard time figuring out these new skills, but after he realizes that Hiro is happy with his... Question: What is the article mainly about? Options: A: The plot and background of the movie Big Hero 6. B: The friendship between Hiro and Baymax in Big Hero 6. C: The reasons for the popularity of Baymax from Big Hero 6. D: What sets Big Hero 6 apart from other animation movies.

Read the article and select the best answer. Article: Noise pollution in cities is causing out health to suffer, according to the World Health Organization. Recently, researchers at the Free University of Brussels in Beigium have developed an applocation: NoiseTube. It allows everyone who downloads it the ability to measure the amount of noise they are exposed to by transforming their smart phone into a sound level meter. NoiseTube works by recording sound levels and GPS locations. Once launched the app shows decibel levels of green or red depending on the level of noise. That information is then sent to the NoiseTube server via the Internet where a "noise map" is produced and then made available to the user. Since its launch, the app has been popular with community groups who want to monitor their own noise levels. According to D'hondt of the Noise Tube project, these groups don't think that city produced noise maps give an adequate interpretation of the level of noise they're experiencing. City produced noise maps are based on statistical models involving very few actual measurements. NoiseTube on the other hand gives a detailed account of the level of noise experienced at a specific time and location. "Ten people walking the same area from 9 to 10 am every day for one week can make a valid and detailed map for an area of a couple of blocks," D'Hondt said. "It's reasonable effort by the community groups to produce these maps, and with it they can go to the authorities and have real evidence about what they're experiencing." So far these sorts of noise maps have been produced for a number of European cities. The app has been downloaded by 10,000 people with 2,700 people registered on the NoiseTube website.
