Article: Old age may not sound exciting.But recent findings offer good news for older pepole and for people worried about getting older. Researches found that people become happier and experience less worry after they reach the age of fifty.In fact,they say by the age of eighty--five,people are happier with their life than they were when they were eighteen years old. The findings came from a survey of more than 340,000 adults in the United States.The Gallup Organization questioned them by telephone in 2008.At that time,the people were between the ages of eighteen and eighty--five.The searches asked questions about emotions like happiness,sadness and worry.They also asked about mental or emotional stress. Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study.His team found that levels of stress were highest among adults between the ages of twenty--two and twenty--five.The findings showed that stress levels dropped sharply after people reached their fifties.Happiness was highest among the youngest adults and those in their early seventies.The people least likely to report feeling negative emotions were those in their seventies and eighties. The study also showed that men and women had similar emotional patterns as they grew older.Hower,women at all ages reported more sadness,stress and worry than men.Researchers say they do not know why happiness increases as people get older.One theory is that,as people grow older,they grow more thankful for what they have and have better control of their emotion .They also spend less time thinking about bad experiences. The researchers also considered possible influences like having young children,being unemployed or being single.But they found that influences like these did not affect the levels of happiness and well--being related to age. Question: When do people feel happier according to the passage? Yes or no, is the answer "After their seventies"?
No

Article: Can people change their skin colour without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin colour. The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science. Scientists have changed the colour of a dark-striped zebra fish to uniform gold by inserting a version of the pigment gene into a young fish. As with humans, zebra fish skin colour is determined by pigment cells, which contain melanosomes . The number, size and darkness of melanosomes per pigment cell determines skin colour. It appears that, like the golden zebra fish, light-skinned Europeans also have a mutation in the gene for melanosome production. This results in less pigmented skin. However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebra fish genes. Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun, which can cause skin cancer. But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng. Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin colours, said Cheng. The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin colour without damaging it like chemical treatment done on Michael Jackson. Question: We can infer from the passage that _ . Yes or no, is the answer "people will be able to change their skin colour without chemical treatment in the future"?
No

Article: If there's a child in your house who likes pixies , nature, or magic, Tinker Bell and the Lost Treasure is sure to be a hit. This beautifully animated film is a first class production in every way, and features the familiar voices of Kristin Chenoweth, Anjelica Huston, Jane Horrocks, Lucy Liu, and Raven Symone. The movie offers up an adventure that's easy enough to follow, but complex enough to hold one's attention, and even throws in a nice little moral about friendship. What can I say? I'm pleasantly surprised. The up-and-coming Mae Whitman voices Tinker Bell herself, a far more dynamic character than we met in Peter Pan. Though Tinker still possesses her fiery temper, it doesn't manifest itself immediately, and takes a backseat to this pixie's many good qualities. As it turns out, Tinker Bell is extremely skilled at tinkering , so she is a natural choice to build a special scepter , for Pixie Hollow's Autumn Celebration. The scepter will hold the moonstone through which the light of the Blue Moon will pass, supplying Pixie Hollow with enough pixie dust for the year ahead. For days, Tinkers works hard on the perfect scepter design while her good friend Terrence does his best to assist. When Terrence accidentally breaks the Moon Stone, Tinker Bell "explodes" and sends him away. One of Tinker's more literal friends finds this extremely concerning, as she doesn't quite understand that the outburst was emotional rather than physical ----- very funny indeed. After hearing the legend of the lost treasure, Tinker Bell strikes out on her own to find a new Moon Stone. She faces many difficulties and meets new friends along the way, but when Terrence comes to the rescue at Tinker's darkest hour, she realizes the value of a truly loyal friend. Though the film is engaging and offers a positive message to young viewers, it's the animation that makes Tinker Bell and the Lost Treasure stand out. Pixie Hollow is a charming, visually stunning world basked in lush color1s. It's... Question: In the writer's opinion, the characteristics of Tinker Bell and the Lost Treasure are the following EXCEPT_. Yes or no, is the answer "the moving love story between Tinker Bell and Terrence"?
No

Article: Sports shoes that work out whether their owner has done enough exercise to promise time in front of the television have been devised in the UK. The shoes- named Square Eyes- contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves , based on the day's efforts. The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University in London, UK. "We looked at current issues and childhood overweight really stood out," she says. "And I wanted to tackle that with my design." Once a child has used up their daily allowance gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps. Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals exactly one minute of TV time. Existing pedometers normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. "It is possible, but it would be a lot of effort," she says. "That was one of my main design considerations." Question: According to Swan, the purpose of her design project is to _ . Yes or no, is the answer "deal with overweight among teenagers."?
Yes
