Q: Write a multi-choice question for the following article, with the given choices and answer: Article: There is a unique place where deserted factories have been transformed into a lively artistic zone - where the city's tradition and heritage meet with cutting-edge art and fashion. This is Redtory. Located at Yuancun Si Heng Lu, not far from the Pearl River of Guangzhou city, Redtory is a creative cultural and industrial zone made up of more than 30 old buildings - mostly red-brick ones. Back in 1956, it used to be the biggest canning factory in China. The factory produced the Can Dace with Black Bean Sauce, an iconic food product in the last century, well-known throughout south-east Asia. After the local government's industrial structure reformations, the canning factory moved away and the workshops were left deserted. There was nothing left but memories in well-preserved Soviet-style buildings. Not long after the noise of the running machines was gone, posters of advertisement and art were found hanging on the wall in the area. To enrich the cultural and artistic life of the people in Guangzhou, the abandoned factories reopened in 2009 - displaying art, fashion and culture of different forms. Redtory is home to more than 40 establishments including art galleries, themed restaurants and design studios. Large international cultural exchange activities, art exhibitions and seminars are often held here, attracting hundreds of thousands of visitors every year. Meanwhile, waste materials have been used wisely instead of being thrown away. For instance, some installations standing around the area are made up of the rusty machines or components from the old canning factory. The shabby and nostalgic appearance combined with fashionable and artistic features makes Redtory uniquely attractive. That may be the reason that Redtory is considered the holy land for young art-lovers in Guangzhou.

Mr Jaycox predicts that within five years, 3D printing technology could become more consumer friendly. But Ki Chong Tran says even current technology can make a difference in a developing country like Cambodia."With 3D printing you can give them tools, and you put it in their hands so they are responsible more for their own development. They learn skills beyond just learning English and becoming a tour guide or something like that or working at a bank.You can actually create things that give value to the world," said Ki Chong Tran.

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Good news for middle and high school students. When it comes to sleeping a little longer, physicians are on your side. On Monday, the American Academy Pediatrics announced its recommendation that middle and high schools start at 8:30 a.m.or later. "Doing so will match school schedules to the biological sleep patterns of adolescents," the AAP writes in a press release regarding its new policy statement called "School Start Times for Adolescents" . "Chronic sleep loss in adolescents is one of the most common public health issues in the U.S.today," according to Judith Owens, director of Sleep Medicine at Children's National Health System. "The research is clear that adolescents who get enough sleep have a reduced risk of being overweight or suffering depression, are less likely to be involved in automobile accidents, and have better grades, higher standardized test scores and an overall better quality of life," Owens said in the press release. "Studies have shown that delaying early school start times is one key factor that can help adolescents get the sleep they need to grow and learn." Even before the AAP's announcement, school districts across the country have been rethinking start times. Earlier this year The New York Times wrote about Dos Santos, a student at Rock Bridge High School. When Dos Santos learned that school officials were considering starting school 30 minutes earlier than the existing time, she became worried.The student gathered others to her cause. In the end, school officials decided against the earlier start time.
