Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

Ex Input:
Lighter and cheaper than high-quality video cameras, today's best smartphones can shoot and edit high-definition (HD) videos. With lower-quality lenses and image sensors, smartphones probably won't replace professional video cameras anytime soon. Still, some creative filmmakers are extending the borders of smartphone moviemaking by shooting professional-quality films using only smartphones. Soon after Apple's iPhone 4 was released, two filmmakers decided to make a short film using only their iPhone 4s. Michael Koerbel and Anna Elizabeth James shot and edited the one-and-a-half-minute film Apple of My Eye in only 48 hours. Audiences were fascinated with the film, in which a man and his grandfather connect emotionally while admiring a model train set in a store window. The filmmakers followed up their success with Goldilocks, an extraordinary spy novel told over nine, three-minute films. Many filmmakers are convinced that smartphone films are here to stay. One sign is their inclusion in major film festivals. In February 2012, organizers of the Berkshire International Film Festival staged the 10 X 10 On North Festival. Entries included Oliver by Hooman Khalili, an award-winning film about a girl whose special powers enable her to brighten the lives of three lonely people. Another entry was Yearlapse'11, a 365-second film by Zsolt Haraszti that describes an actual journey he made from New York to London. During the festival, which ran from February 16 to 26, these and many other smartphone films were shown at the Beacon Cinema in Pittsfield, Massachusetts. Similar festivals in Canada and South Korea have given smartphone filmmakers opportunities to show off their creative work.

A new study found that inner-city kids living in neighborhoods with more green space gained about 13% less weight over a two-year period than kids living among more concrete and fewer trees. Such findings tell a powerful story. The obesity epidemic began in the 1980s, and many people think it results from increased portion sizes and inactivity , but that can't be everything. Big Macs and TVs have been with us for a long time. "Most experts agree that the changes were related to something in the environment," says Thomas Glass of the Hopkins School of Public Health. That something could be a shrinking of the green. The new research, published in the American Journal of Preventive Medicine, isn't the first to associate greenery with better health, but it does get us closer to identifying what works and why. At its most straightforward, a green neighborhood simply means more places for kids to play -- which is important since time spent outdoors is one of the strongest links to children's activity levels. Glass warns that most studies don't necessarily prove a link between greenness and health, but they're helping _ action. In September the U.S. government approved the No Child Left Inside Act to encourage public initiatives aimed at exposing kids to the outdoors. Finding green space is, of course, not always easy, and you may have to work a bit to get your family a little grass and trees. If you live in a suburb or a city with good parks, take advantage of what's there. Your children in particular will love it -- and their bodies will thank you.
