[EX Q]: Article: Nowadays with the development of agriculture, farmers use more technology. 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 make a mistake that you'll live with for the rest of your life."

[EX Q]: Article: Most shoplifters agree that the January sales offer wonderful opportunities for the hard-working thief. With the shops so crowded and the staff so busy, it does not require any extraordinary talent to help you to take one or two little things and escape unnoticed. It is known, in the business, as "hoisting". But the hoisting game is not what it used to be. Even at the height of the sales, shoplifters today never know if they are being watched by one of those evil little balls that hang from the ceilings of so many department stores above the most desirable goods. As if that was not trouble enough for them, they can now be filmed at work and obliged to attend a showing of their performance in court. Selfridges was the first big London store to install closed-circuit videotape equipment to watch its sales floors. In October last year the store won its first court case for shoplifting using an evidence a videotape clearly showing a couple stealing dresses. It was an important test case which encouraged other stores to install similar equipment. When the balls, called sputniks, first make an appearance in shops, it was widely believed that their only function was to frighten shoplifters. Their somewhat ridiculous appearances, the curious holes and red lights going on and off, certainly make the theory believable. It did not take long, however, for serious shoplifters to start showing suitable respect. Soon after the equipment was in operation at Selfridges, store detective Brian Chadwick was sitting in the control room watching a woman secretly putting bottles of perfume into her bag. "As she turned to go," Chadwick recalled, "she suddenly looked up at the 'sputnik' and stopped. She could not possibly have seen that the camera was trained on her because it is completely hidden, but she must have had a feeling that I was looking at her." "For a moment she paused, but then she returned to counter and started putting everything back. When she had finished, she opened her bag towards the camera to show it was empty and hurried out of the store. "
Answer: there are so many people in the store

[EX Q]: Article: The oldest and hardest cow beef may be made as tender and tasty as young and choice met. "This declaration was made by the French physicist Denis Papin in book published in 1681, which described his "New Digester" or pressure cooker. It was a cast iron pot with an air-tight lid, which allowed liquids to boil at a higher temperature than usual, and so it cooked food in a quarter of the time. The food was cooked by pressurized steam being forced through it at about 121degC. All pressure cookers were made of cast iron until 1905, when the first aluminum model was made in America. In 1938, Alfred Vischer, a man from Chicago, U. S. A., designed a simple interlocking pan and lid, and an improved pressure-tight seal --a replaceable rubber sealing ring. When Vischer's patent expired in 1954, many companies entered the field, and the rapid pressure cooker became popular with people with people who had little time to cook or had to supply food for unexpected guests.
