Question: Article: Let Children Roam Free Everyone agrees that playing outside keeps children thinner. The loss of opportunities for outdoor play is one of the main causes of childhood obesity. What is more remarkable is the growing evidence that children's mental health and emotional well-being are enhanced by contact with the outdoors, and that the restorative effect appears to be strongest in natural settings. Researchers are convinced of the depth of the connection between children's well-being and the environment, claiming that contact with nature may be as important to children as good nutrition and adequate sleep. But now children seem to get less touch with outdoor activities. The root causes of the dramatic loss of children's freedom lie in changes to the very fabric of their lives over the last 30 years or so. The growth in road traffic, alongside poor town planning and shifts in the make-up and daily rhythms of families and communities, have left children with fewer outdoor places to go. These changes coincided with the "culture of fear": a generalized anxiety about all imaginary kinds of threats, even though children are statistically safer from harm now than at any point in human history. These physical, economic and social changes and fears have been made use of by manufactures and advertisers, whose products and messages both reinforce the logic of keeping children virtual prisoners, and force us to compensate them in the only way our cash-rich, time-poor society seems to know: by spending money on them. Government must bear some of the blame for keeping children prisoners indoor, through their promotion of planning policies that favour cars over communities and profit over people. The real planning crimes lie in housing companies occupying attractive parks and green spaces, and in town plans that force families to depend largely on their cars. There is no doubt that traffic danger, unlike stranger danger, is a real threat to children and a constant worry for parents. Around 100 child pedestrians are killed every year, a figure that puts the UK near the bottom of Europe's child road safety league. It is no surprise that figures show a steady fall in children walking or cycling over the last twenty years, to the extent that while over 90% of children own a bicycle, just 2% cycle to school. Also, 30% of children aged eight to ten never play outside without an adult watching over them. In a single generation, the "home habitat" of a typical eight-year-old----the area in which children are able to travel on their own- has shrunk to one-ninth of its former size. Health experts have even created a new word, "obesogenic", to describe those aspects of our lives that make us fat, and top of the list is the design of streets, towns and cities.
Answer: exercising the mind

Answer: Playing outside is just as important as _ .

Question: Article: If you saw another kid ride her bike too fast around a corner and fall down, you might ride your bike more slowly on that turn. Yes, we humans are very sensitive to others' mistakes. And the same is true for other animals. Animals mess up all the time. They might eat poisonous leaves, fall off a tree or let their prey slip away. By watching others fail, an animal can avoid making the same mistakes, thus improving its chance of survival. Scientists suspected that one part of the brain helps animals process information about others' errors. Cells in that part appear to become more active when a person sees someone else making a mistake. But researchers didn't know whether individual cells in this part of the brain play different roles in _ errors. To investigate the brain's response to errors in more detail, the researchers taught a game to two macaques, a type of monkey. One monkey could press a yellow or green button while the other watched. If the first monkey pressed the right button, the team gave both animals a treat. Every couple of rounds, the two monkeys switched roles. Meanwhile, the scientists monitored individual cells in the animal's brains. When the first monkey messed up the game by pressing the wrong button, a group of cells in the second monkey's brain fired. But if the second monkey also made the wrong choice during its turn, some of the cells in that group didn't respond. Those unresponsive cells reacted specifically to mistakes made by others, not to the monkey's own mistakes. Scientists believe other parts of the brain also might help people process information about another's errors. "You start to think about this other person and see things from his angle. " Ellen de Bruijn, told Science News. She studies the brain at the University of Leiden in the Netherlands.
Answer: others' mistakes

Answer: In the experiment mentioned, those unresponsive cells are only sensitive to _ .

Question: Article: Surrounded by far - away mountains and nearby downtown buildings, a large open field was filled with lines of blue and white houses. Several kids were laughing and playing table tennis inside a play room. Some old men were playing Chinese chess and a crowd of women chatting in front of two TV sets. Two weeks after the deadly earthquake, the first batch of 1,500 people inprefix = st1 /Dujiangyan,SichuanProvince, one of the worst earthquake - hit cities, has finally settled into a peaceful life in a newly built temporary community. "Compared with tents, these simple houses make us feel more at home. My grandchild can go on with his study here," said an old woman. These one - floor buildings are totally different from their old homes. Instead of cement and bricks, the houses are made of light- weight steel or foamed plastic and can stand a 7 - magnitude earthquake. Each of the houses, featuring about 20 square meters, serves as a three - person family unit. The units have three beds and electricity. Each has its own postal address. Communal facilities will include showers, toilets and refectories . It is also planned that there should be one primary school, one hospital and one supermarket for every 1,000 homes. Everything will be free to the residents in possession of their identity cards, and work has already started in looking for jobs for the community. "More than 1.5 million such _ houses will be built inSichuan, which are expected to be in use for at least three years," said Minister of Housing and Urban - Rural Development Jiang Weixin. The government said over 5.93 million rooms in Sichuan had been leveled in the quake and more than 11 million people, which even outnumber the entire population of some countries such as Norway and New Zealand, became homeless. It is planned that all the victims will be housed by early August, and that they will stay in the temporary houses for between three and five years until permanent homes are built.
