Article: BEIJING, Jan. 11(Xinhuanet)-- Sleeping a little bit longer a day might help fight against obesity , a recent study shows. The research-- published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research-- after comparing people of normal weight- a body mass index of less than 25- with those who were overweight or _ , found that sleeping for an extra 20 minutes each night could offer a pain-free way to lose weight. Insufficient sleep is linked with changes in hormone levels that may stimulate appetite. A series of studies in recent months have shown that the less people sleep, the heavier they tend to be. American researcher Robert Vorona from Eastern Virginia Medical School in Norfolk and colleagues have now examined the relationship between people's self-reported sleep time per 24 hours and their body mass index(BMI). They found that total sleep time and BMI were inversely correlated was total sleep time decreased, BMI increased, except in the severely obese group." Americans experience insufficient sleep and corpulent bodies. Clinicians are aware of the burden of obesity on patients," the study said. "Our findings suggest that major extensions of sleep time may not be necessary, as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index," it added. "We warn that this study does not establish a cause-and-effect relationship between restricted sleep and obesity (but) investigations demonstrating success in weight loss via extensions of sleep would help greatly to establish such a relationship." In November 2004, researchers from Columbia University in New York City, New York demonstrated a clear link between the risk of being obese and hours of nightly sleep, finding that people aged 32 to 59 who slept four hours or less per night were 73% more likely to be obese than people who slept between seven and nine hours per night.

Article: We thought we had it all---a beautiful house, three healthy children and one more on the way, two cars, a couple of four-wheelers for entertainment---and we loved it. Then, the market turned and my husband's job at a construction company was gone. The company was closing down for good.We both started looking for jobs right away, but there weren't any to be found. With each passing day we were getting increasingly worried and we continued to work together in order to pull our family through. _ I felt feelings of admiration for my husband that I hadn't felt in years. That's why it was so hard for me to watch him blame himself for our present situation. I continually asked him to stop, but he seemed to want to punish himself for not having a job. Finally, one afternoon I pulled him aside and said, "We have four healthy children and each other. That's what's important. That makes you a rich man." " But what if we lose the house? They'll hate me--you'll hate me," he replied. I smiled at him and put my hands on both sides of his face to make him look me in the eye. "No matter where we live I will be happy -as long as I have you." I smiled again. In all the struggling together I had found that deep love for him that I had on the day we said "I do". I could see his shoulders and neck relaxed. He held me close and we were able to talk and plan and dream together in a way that we hadn't for quite some time. It was a turning point for us as a couple and a family. We are still struggling for out better life, but I consider us well-off because we have something that money can't buy and no one can take away from us. Question: We can learn from the passage that _ . Yes or no, is the answer "both of them were worried about joblessness."?
No

Q: Article: It's hard to be the bearer of bad news,but most of IKEA's print and digital fascinating shots of picturesque rooms and products are fake.Those beautiful,"natural-looking" photos of gorgeous rooms and kitchens are mostly the work of computer magic,adjusted and corrected until they're picture-perfect. Martin Enthed,IT manager for IKEA's in-house communications agency,revealed,"In 2012,12 per cent of its product and concept images was CGI-rendered,increasing to 25 per cent in 2013.Since then,that percentage of rendered images appearing in the company's catalogue and online has tripled.75 per cent of the furniture company's product images today are created by computers." It's a move that first caught the attention of photographers and graphic designers a few years back when the furniture giant announced it would cancel photoshoots in favor of computer-generated imagery(CGI). Enthed said IKEA began shifting equipment in 2009 when company officials called in his team and said they weren't pleased with some previous photos and CG images. "So we looked at all the images they said weren't good and the two of three they said were great,and the ones they didn't like were photography and the good ones were all CG,"Enthed said."Now we only talk about a good or bad image - not what technique created it." It's a not-so-secret strategy used by top companies specializing in home and furniture design,though many consumers remain oblivious. The company claims the shift is another way to reduce its environmental footprint,saying constructing digital files produces less waste.It also helps the home furnishing empire's pocketbooks. Question: What directly led IKEA to adopt CGI on a larger scale? Yes or no, is the answer "Company officials' reaction to works."?
A: Yes

Article: When Mrs.Joseph Groeger died recently in Vienna,Austria,people asked the obvious question,"Why did she live to be 107?" .Answers were provided by a survey conducted among 148 Viennese men and women who had reached the age of 100.Somewhat surprising was the fact that the majority had lived most of their lives in cities.In spite of the city's image as an unhealthy place,city living often provides benefits that country living can lack.One factor seems to be important to the longevity of those interviewed. This factor is exercise.In the cities it is often faster to walk short distances than to wait for a bus.Even taking public transportation often requires some walking.Smaller apartment houses have no elevators ,and so people must climb stairs.City people can usually walk to local supermarkets. Since parking spaces are hard to find,there is often no alternative to walking. On the other hand,those who live in the country and suburbs do not have to walk every day.In fact,the opposite is often true.To go to school,work,or almost anywhere else,they must ride in cars. Question: A conclusion that can be drawn from this passage is that _ Yes or no, is the answer "walking is a healthful exercise"?
(A).
No
