Problem: Given the question: Write a multi-choice question for the following article: Article: Kindergarten outside? Yes, indeed. It's part of a growing worldwide trend toward outdoor education. The schools are called forest kindergartens. The numbers are small so far in the U.S., but the idea is well established in Europe, with schools in Scotland, England, and Switzerland. By far the most such schools are in Germany, which has more than 400 forest kindergartens. Some schools feature several hours of outdoor schooling. This is certainly the case with the Waldorf School of Saratoga Springs. Children there will be venturing out on the nearby Hemlock Trail to learn more about the natural world. Some lessons are focused on nature; others are academic topics delivered in a natural setting. In all cases, students are active-not sitting at desks or on mats on the floor but walking, running, jumping, solving problems like how to get the mud off the bottoms of their shoes before their parents find out. Seriously, the focus is on activity at these schools. Studies have shown that children's immune systems actually get stronger after all of the outdoor activity, and that graduates of forest kindergartens show a higher ability to learn when they progress through their academic careers. Other schools are all outdoors, all the time. This is the case with the Cedar Song Nature School, on Vashon Island, Washington. Students at this school spend their whole three-hour day outdoors, in a private five-acre forest, doing all kinds of physical activities. At these forest kindergartens, students learn science by observing and doing it, learn math by applying it to the natural world around them, learn letters and words by putting them together using sights and sounds. These students learn how to get along with one another, individually and in a group. They also develop healthy levels of self-confidence. Nowadays many children become obese because of sedentary activities like watching television and playing video games. These outdoor schools give children chances to learn just as much, if not more, from opening their eyes...

input question: Write a multi-choice question for the following article: Article: On Friday, Japanese researchers announced a population clock that showed a dangerous situation that the Japanese nation would disappear in 1,000 years if the falling birth rate kept the present level. Researchers in the northern city of Sendai said that Japan's population of children aged up to 14, which now stands at 16.6 million, was falling at the rate of one child per 100 seconds. It would lead to a terrible result that there would be no children left in Japan in 1,000 years. "If the rate keeps falling at that rate in our country, there will only be one child who is able to enjoy the following Children's Day left on May 5th, 3011," said Hiroshi Yoshida, a professor at Toholu University. "But 100 seconds later, a national disaster that there are no children left in Japan will happen," he added, "The nation's people will disappear for the birth rate has fallen to the level that every woman has no more than two children, which started in 1975." Yoshida said they created the population clock to make Japanese people pay close attention to that problem for their nation's future. Another study showed that Japan's population was expected to fall to one third of the present population amount: 127.7 million in the next century. The Japanese government predicted that the birth rate would just become 1.35 children per parents within 50 years. At the same time, Japanese life expectancy which is expected to ascend from 86.93 years in 2010 to 90.93 years in 2060 for women and from 79.64 years to 84.19 years for men has already been one of the highest in the world. More than 20 percent of the Japanese are aged 65 or over. It means that Japan has become one of the countries with aging populations in the world. The problem of aging populations is a headache for the government and the Japanese economy because there are fewer and fewer workers who can make money for the country. However, the government has to face the terrible situation that it needs to offer a growing number of pensions.???

Please answer this: Write a multi-choice question for the following article: Article: Several years ago, the mayor of Chicago, Illinois, visited Germany, a leader in green roof design. Later he decided to have vegetation planted on Chicago City Hall. Today, the tops of many other buildings also look like parks. In Canada, the Coast Plaza Hotel in Vancouver has a forest on its roof. New York City has an unusual example farm for hydroponics. The farm is on a boat called the Science Barge. Rainwater and river water are used to grow lettuce, tomatoes, cucumbers and peppers. The farm shows the possibilities for designing rooftop systems. Green roofs are designed to save energy and capture rainwater. Rooftops covered with plants help keep buildings cool. They can extend the life of a roof. And they can reduce water running off into streets and storming water systems. Experts say green roofs usually do not get much above 27degC. So temperatures might not be a problem for growing. But rooftop gardeners have to be careful not to put too much weight on the roof. This is true whether plants are grown in soil or water. Earlier in 2008, researchers in Texas reported that green roofs can reduce a building's air conditioning costs by about onefifth compared to blacktop roofs. But they also reported that not all green roofs perform equally well. They found that designs differ in their ability to keep buildings cool and to capture rainwater. The researchers put experimental roofs on top of metal insulated boxes, to recreate green roof conditions. The study compared products from six companies to help businesses understand how to improve their designs. Each rooftop had sixteen different kinds of plants native to Texas. The researchers say the presence of native plants likely helped all the green roofs capture water better compared to sedums. Sedums are plants that need little water and often are used on green roofs. The native plants could take in more water and release more of it to the atmosphere.
