Are the remains buried in a French castle really those of the master? Was the "Mona Lisa" a self-portrait in disguise ? A group of Italian scientists believe the key to solving those puzzles lies with the remains, and they say they are seeking permission to dig up the body to conduct carbon and DNA testing. If the skull is undamaged, the scientists can go to the heart of a question that has fascinated scholars and the public for centuries: the identity of the "Mona Lisa." Recreating a virtual and then physical reconstruction of Leonardo's face, they can compare it with the smiling face in the painting. "We don't know what we'll find if the tomb is opened. We could even just find grains and dust," says Giorgio Gruppioni, an anthropologist who is participating in the project. "But if the remains are well kept, they are a biological record of events in a person's life, and sometimes in their death." Silvano Vinceti, the leader of the group, said that _ in charge of the said burial site at Amboise Castle early next week. Leonardo moved to France at the invitation of King Francis I, who named him "first painter to the king." He spent the last three years of his life there, and died in 1519 at age 67. The artist's original burial place, the palace church of Saint Florentine, was destroyed during the French Revolution and remains that are believed to be his were eventually reburied in the Saint-Hubert Chapel near the castle. "The Amboise tomb is a symbolic tomb; it's a big question mark," said Alessandro Vezzosi, the director of a museum dedicated to Leonardo in his hometown of Vinci. Vezzosi said that investigating the tomb could help identify the artist's bones with certainty and solve other questions, such as the cause of his death. He said he asked to open the tomb in 2004 to study the remains, but the Amboise Castle turned him down. The group of 100 experts involved in the project, called the National Committee for Historical and... Question: Which of the following statements is true according to the passage? - Scholars have the same opinion on DNA testing - Scientists doubt if the remains are those of da Vinci - The identity of "Mona Lisa" has already been proved - Alessandro Vezzosi got permission to open the tomb
Scientists doubt if the remains are those of da Vinci

However, they are being told more needs to be done to stop them injuring at work. One in five British workplace deaths happens in agriculture even though farmers are only a small part of the working population. During the year 2012/13 there were 1,061 injuries in total and it is thought many more go unreported. Jim Chapman from Warwickshire had his arm torn off by farm machinery seven years ago when he was 23. "You don't realize how much you rely on your second arm until it's gone," he said. He fell against a PTO shaft , a spinning metal bar at the back of a tractor. "It catapulted me from one side of the machine to the other," he said. "I landed on the floor, minus all my clothing. My left arm had been torn off." He admits that the machinery was missing part of its proper safety guard. "But again," he added, "it was a rushed day. There were a few machines that didn't work. Also, I was getting behind with the jobs." Over the last 10 years, other industries that you'd think of as dangerous, like building or quarrying , have lowered the number of workplace deaths and injures. In the farming industry though, deaths remain high with 34 deaths in 2012/13. Judith Hackett, the chair of the Health and Safety Executive (HSE) says it is "not acceptable" that the accident statistics for farming are still high. "People in farming don't have minor injuries. When they get injured, it's bad." She said. "When I said to the National Farmers' Union (NFU) that if I had sons I would not want them to work in agriculture, it really made them sit up and take notice." There's a whole host of reasons why farming is as dangerous as it is. It is a very rough industry. Also, it's often because people are left alone. They could be young and inexperienced, or older people, who would have retired maybe 5 or 10 years ago in other industries. Jim wants others to learn from his experience. "Look at what you're doing before you go running in," he said. "You could... Question: Jim Chapman was injured in the workplace mainly because _ . - he crossed the machinery - he didn't notice the PTO shaft - the safety guard of the machinery was gone - he was standing at the back of the tractor
the safety guard of the machinery was gone

Article: Ask a group of elderly people what it was about their lives that made them happiest overall, and they'll probably mention some warm relationships with family and friends. If you're satisfied with your social life, according to psychologists, you tend to be satisfied with life in general. From the point of my 50s, I'd say that sounds about right. Some of my happiest moments are the ones I spend with my husband, a few close relatives, and a handful of very good friends who know me well and like me anyway. But the more I read about how social media are interfering with good old-fashioned friendship, creating virtual bonds that can't quite take the place of real ones, the more I wonder just how today's 20-somethings will look back on their own lives when they're my age. After all, much crucial relationship building work is done in the 20s. According to research by the late Bernice Neugarten of the University of Chicago, who helped launch the academic study of human development, people choose most of their adult relationships, both friends and lovers, between the ages of 22 and 28. The friends we make in our 20s are not only best friends forever; they're also our first truly chosen friends. And choosing how to commit to these friendships is an essential psychological task of the 20s. But with so much of friendship in this age group now being developed online, an essential question is what the effect of that interaction is. A study, conducted in 2010 by Craig Watkins and Erin Lee of the University of Texas at Austin, investigated the Facebook habits of 776 young people between the ages of 18 and 35. "Whether it is a wall post, a comment, or a photo," they wrote, "young people's engagement with Facebook is driven, primarily, by a desire to stay connected to and involved in the lives of friends who live close by, far away, or have just entered into their lives." This kind of constant contact can be efficient, but it can also be upsetting. For one thing, it adds a new layer of concern to a young person's... Question: What was the aim of the study conducted by Craig Watkins and Erin Lee? - To know about the 776 young people's Facebook habits. - To find out how social media affect real-world social life. - To help young people stay connected to the lives of friends. - To investigate what kind of people prefer online interactions.
