Article: Turning the lights out or wearing a blindfold while eating could be a quick way to lose weight, according to scientists. The simple trick works because it stops diners eating for pleasure rather than for calories. It also triggers a part of the brain that is worried that unseen food may go bad. An experiment by the University of Konstanz, in Germany, found that people who were blindfolded consumed nine percent fewer calories before they felt full, compared to those who could see. They also vastly overestimated how much they had eaten because they could not see how much was left on the plate. Blindfolded volunteers estimated they had eaten 88 percent more than they actually had. Scientists believe that not seeing food on the table also allows the body to know when it is full in real time rather than remembering past experiences where it might have taken a full plate to feel full. In the experiment, 50 people were blindfolded and 40 were allowed to see their food. All were told not to eat within two hours of the experiment. They were then given three 95g bowls of chocolate ice cream and invited to eat for 15 minutes. Their bowls were taken away and the remaining ice-cream weighed, while the participants were quizzed on how much they thought they had eaten. On average the group who could see ate 116g while the blindfolded groups ate 105g. However, the blindfolded group believed they had eaten 197g while compared with 159g for the non-blind volunteers. They were also asked how pleasant the ice-cream tasted and the blindfolded group rated lower than those who could see. "The experienced pleasure of eating was significantly lower in the blindfolded group. Not seeing the food might have decreased the appetite. Sight plays an important role in the eating experience and in the overall dining experience." Previous studies have shown that the visual influence of food plays a large part in the taste. While restaurants that allow diners to eat in the dark state that it triggers other senses, in fact eating in darkness... Question: The main purpose of the passage is to _ . Yes or no, is the answer "inform the readers of the result of an experiment"?

Article: In the wee hours of the morning, a 26-block neighborhood in San Diego, California, is quiet and peaceful. Most local people won't rise for another five hours, but Ka-sim Morris, 44, is up and out at 2 am. He paints over graffiti , looks out for criminal activity, or installs new waterlines. At about 5 am, Morris takes a quick coffee break and watches for the community's first signs of life. "If I won the lottery, I would still stay in my community and keep my job," Morris confesses. He is the maintenance supervisor for the Adams Avenue Business Association, one of San Diego's 16 Business Improvement Districts (BIDS). A BID is an area in which local businesses agree to pay higher taxes to help rebuild the community. The extra money from higher taxes is used to support neighborhood activities such as installing streetlights, removing graffiti, planting trees, and paying people like Morris, who complete the tasks that help make the community beautiful. For six years, Morris did this work for free! "We thought he deserved a paying job," says Scott Kessler, the association's executive director. Last January, Morris was recognized for his long-term contributions at an awards dinner. "Morris was an obvious choice for the award," Kessler continues. "He helps make our community the special place that it is." Marc Nguyen, 10, who nominated Morris as their Hometown Hero, agrees. "I see him every day cleaning things up and helping other people," says Marc. Morris modestly explains how many people help make the Normal Heights neighborhood special. "I am not the only one," he says. But Morris is the only one responsible for his demanding work schedule. "Everyone thinks I'm crazy," explains Morris. "But to get the job done right, it's best to start in the early morning." Does that sound like a hero talking, or what? Question: The attitude of the local people towards community tasks is _ . Yes or no, is the answer "enthusiastic"?
No

Q: Article: Being green is everywhere these days, whether it is in the school, factory or anywhere on the Internet. This is because our planet is in danger, losing resources, polluting resources and destroying ecosystems . Different species are dying because we can't take care of our home. Now ask yourself why you don't want a green healthier lifestyle and to save animals. Keep _ in mind as you read on. There are many ways to be green, first of all, everyone should recycle; it's something easy and helps our planet in many ways. All you'd have to do is put recycling in recycling and garbage in garbage. Another popular thing is to try your best not to drive a car. Sometimes you can just walk, bike, or take a subway. This ensures that our air won't be polluted, which in turn helps our lungs and everything else on our planet. Next thing is saving energy. We can do this by not using too much heat or air conditioning in summer or winter. It's not preferable because it's hard, but you can try and put your washing machine on cold whenever possible and try to keep electronics out of the rubbish. What's more, remember to stop drinking from plastic bottles because plastic can only be used once and if used many times, it will become unhealthy. So you'd better use a glass or buy a reusable water bottle. The last and most important thing is, spread this news to the world and tell them what's happening in our world. I've only listed a small part of the endless possibilities to save this world. The least you can do is do the simple ones. Question: How many ways to be green are mentioned in the passage? Yes or no, is the answer "Five."?
A: No

Article: A victim of climate change A polar bear's dead body found on the Arctic island of Svalbard, the northernmost part of Norway, has shocked experts who say climate change may be to blame for the death. The starved polar bear in Norway was said to be in good bones by the time a group of explorers came across its body in July. The bear is thought to have been heading north in a desperate search for sea ice that would allow it to hunt for seals."From his lying position in death, the bear appears to simply have starved to health in April when the Norwegian Polar Institute examined and labeled it. However, the animal was reduced to skin and bones and died where he dropped," polar bear expert Dr. Ian Stirling, a professor at the University of Alberta said, "He had external suggestion of any remaining fat, having been reduced to little more than skin and bone." Stirling believes the bear starved to death as a result of a lack of sea ice which the animals use as a platform for hunting seals. That may also explain why the 16-year-old male bear was found about 155 miles north of where it was seen in April. Arctic sea ice reached a record low in 2012, according to a report released this week by the National Oceanic and Atmospheric Administration that pointed to continued signs of climate change. The International Union for Conservation of Nature currently classifies polar bears as _ e on its Red List of Threatened Species. Question: What is the author's attitude to the incident? Yes or no, is the answer "Concerned."?
