Article: Look, this is the first plane in the world to be created using the new technology of "3D printing". The airplane was built using only a computer--but it can fly at a speed of 100mph and has a two-meter wingspan. It was produced using a special nylon laser printer that builds up something layer-by-layer. The parts were made separately and attached using a "snap fit" technique so the aircraft could be put together without tools in minutes. No fasteners at all were used in the manufacture of the plane. Unmanned and electrically powered, the plane can travel in near silence and is also equipped with a small autopilot system. The special production process used is known as "laser sintering "and allows the designers to create shapes and structures that would normally include costly manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from your own design to first flight in days, while using traditional materials and techniques would take months. And because no tooling is required for manufacture, major changes to the shape and scale of the aircraft can be made with no extra cost. Professor Jim Scanlon, who led the team, said, "The process allows the design team to revisit historical techniques and ideas that would have been too expensive using traditional manufacturing." He added, "This form of structure is very firm and lightweight, but very complex. If it was manufactured traditionally it would require a large number of individually tailored parts that would have to be connected or fastened at great expense." The new printed plane is known as the Southampton University Laser Sintered Aircraft--or SULSA for short--and is part of a wider project using cutting-edge manufacturing techniques. The University of Southampton has been at the leading position of Unmanned Aerial Vehicle development since the early 1990s. Question: Professor Jim Scanlon believes they can _ with their techniques. Yes or no, is the answer "produce firmer and lighter real planes easily"?
No

Article: My grandson, Daniel, and I have always been very close. When Daniel's father remarried after a divorce, Daniel, who was eleven, and his little sister, Kristie, came to live with us. My husband and I were more than happy to have kids in the house again. Things were going along just fine until the diabetes I've lived with most of my adult life started affecting my eyes, and then more seriously, my kidneys . Then everything seemed to fall apart. Three times a week, I had to go to the hospital to be hooked up to a dialysis machine . I was living, but I couldn't really call it a life -- it was an existence. I had no energy. I dragged myself through daily chores and slept as much as I could. My sense of humor seemed to disappear. Daniel, seventeen by then, was really affected by the change in me. He tried as hard as he could to make me laugh, to bring back the grandma who loved to clown around with him. Even in my sorry state, Daniel could still bring a smile to my face. But things were not improving. After a year on dialysis, my condition was deteriorating and the doctors felt that if I didn't receive a kidney transplant within six months, I would surely die. No one told Daniel this, but he knew -- he said all he had to do was look after me. To top it off, as my condition worsened, there was a chance that I would become too weak to have the transplant surgery at all, and then there would be nothing they could do for me. So we started the tense and desperate wait for a kidney. I was adamant that I didn't want a kidney from anyone I knew. I would wait until an appropriate kidney became available, or I would literally die waiting. But Daniel had other plans. The time that he took me to my dialysis appointments, he did a little secret research on his own. Then he announced his intention to me. "Grandma, I'm giving you one of my kidneys. I'm young and I'm healthy ..." He paused. He could see I wasn't at all happy with his offer. He continued, almost in whisper, "And most of all, I couldn't stand it if you... Question: When grandma was at her lowest, what did Daniel do to bring her back to her usual life? Yes or no, is the answer "He tried his best to make her laugh."?

No

Ques: Article: People should go outside and absorb some sunshine to help increase their vitamin D levels, some experts say. Arthritis Research UK. which is a British medical research organization dedicated to curing arthritis , says vitamin D deficiency can cause bone loss, muscle function problems and, in some cases, rickets in children. The government recommends vitamin D supplements for pregnant women and children aged under five. But on sunny days, a few minutes outdoors should achieve the same results, Arthritis Research UK says. Figures show that up to a quarter of the population has low levels of vitamin D in their blood and the majority of pregnant women do not take vitamin D supplements. People aged over 65, pregnant and breast-feeding women and children aged six months to five years old are thought to be most at risk. Vitamin D is essential to help the body absorb calcium from food. Low levels of vitamin D can result in serious problems. Alan Silman, the medical director of Arthritis Research UK, said, "When the days are sunny, go out for a few minutes and expose your face and arms to the sunshine." But he also had a warning on overexposure. "Don't allow your skin to go red, and take care not to burn, particularly in strong sunshine and if you have fair or sensitive skin. From June to August, just 15 minutes is generally enough time." "In less sunny months," Alan Silman added, "we recommend that people add more vitamin D in their diet by eating more oily fish such as salmon, tuna, and foods rich in vitamin D, such as cereals ." Question: In which column of a newspaper could we possibly find this text? Yes or no, is the answer "Health."?
Ans: No

Ques:Article: Urban legends are stories that are told and believed in many places.Too many places,in fact.It simply isn't credible that the same unlikely events take place in so many different towns.For some reason,though,that particular set of events appeals to the imagination and the tale spreads. A very common North American urban legend concerns a mad man in the woods.A dangerous mad man has escaped from a hospital for the mentally ill.At some point in his life he has lost a hand and it has been replaced by a hook.A boy and a girl are out dating,sitting in a car.They hear on the radio that the area is dangerous,so they drive off.When they arrive home they find a bloodstained hook hanging on the door handle of the car door next to the girl. Missing kidney stories are fairly common.Of course,the details are variable.It might be a woman waking up in a strange hotel in Bangkok,or a man finding himself in a cold bath in Toronto.or a young man with faint memories of wild disco party,but they all find a flesh wound,and discover that one of their kidneys has been removed and,probably, sold. The back seat killer has plenty of drama.A woman gets into her Car late at night.Another Car follows her, speeding,flashing lights and really frightening her.She gets home and keeps on pressing the horn.Her husband runs out.The chasing car stops.The husband demands to know why the driver has been frightening his wife.He says he saw a strange man get into the back of the car as the wife got in,and then hide.They go and look,and there is a dangerous mad man... Question: Why does the woman driver keep on pressing the horn? Yes or no, is the answer "To made her husband aware of something urgent."?
