Q: Read the following article and select the best answer. Article: Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer, saying studies showed a clear link. "Our suggestion is for people to increase their intake, through diet or a vitamin supplement," Dr. Cedric Garland said in a telephone interview. Garland's research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. "There's nothing that has this ability to prevent cancer," he said, urging governments and public health officials to do more to fortify foods with vitamin D.Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units (IU) a serving. People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day, Garland said, adding that it was well within the safety guidelines established by the National Academy of Sciences. The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine. African Americans, who don't produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake, the authors said. Question: According to the passage, people are advised to take more Vitamin D because _ . - it is nutritious - it can't harm people's health - it is not taken enough every day - it can lower cancer risk
A: it can lower cancer risk

Q: Read the following article and select the best answer. Article: For more than 40 years, scientists have sought to learn how well human beings can adapt to long periods in space. The International Space Station continues to provide valuable knowledge about spaceflight. But an earlier space station, Skylab, helped make the current space project possible. Canadian astronaut Chris Hadfield sang aboard the International Space Station on May 12, 2013. His music video has become extremely popular. The astronaut played his own version of David Bowie's song Space Oddity. He performed while floating weightlessly, with images of planet earth and space appearing in the window behind him. Chris Hadfield recently returned home after nearly five months on the space station. For him, the long flight produced a hit video on YouTube and no major physical problems. But 40 years ago, scientists did not know how humans would react to long-term spaceflight. To find out, NASA, the American space agency, launched Skylab in May, 1973. Over nearly a year, three teams of astronauts visited Skylab for stays of between 28 to 84 days. They learned how people react to extended periods in space. Gerald Carr commanded Skylab 4. He spoke at a NASA event marking the 40th anniversary of Skylab's launch. He said that the loss of the body's muscle mass was a main concern. Astronauts on Skylab used exercise equipment to stay strong. The astronauts spent their workdays carrying out experiments, including biomedical research. Marshall Porterfield is the director of NASA's Space Life and Physical Sciences Division. He says the Skylab astronauts' understanding of their own ability to deal with long-term spaceflight continues to help current astronauts. NASA says the next step for life away from Earth is a year-long space station mission, set for 2015. Question: Why was Chris Hadfield's song so special? - It was performed in space. - It was created by an astronaut. - It was a very familiar song. - It was first sung by a famous singer.
A: It was performed in space.
