Article: There was once a farmer who lived near a road. It was not a busy road,but from time to time,cars passed the farm. Near the farm gate, there was a large hole in the road. this hole was always full of water, and the drivers of the cars could not see how deep the hole was. They thought it was probably not deep.So when they drove into the hole, they could not drive out because it was so deep. The farmer did not spend much time working on his farm. He spent most time watching the hole. Whenever a car drove into it, he would pull the car out with his tractor and he would charge the drivers for much more money than they had expected. One day, a driver of a car said to him, "You must have made a lot of money pulling cars out of this hole night and day." "Oh no," the farmer said, "I don't pull cars out of the hole at night. At night I fill the hole with water."

Article: The federal school lunch program for 30 million low-income children was created more than half a century ago to combat malnutrition . A breakfast program was added during the 1960s, and both attempted to improve the nutritional value of food served at school. More must be done to fight the childhood obesity epidemic, which has caused a frightening peak in weight-related disorders like diabetes, high-blood pressure and heart disease among young people. The place to start is schools, where junk food sold outside the federal meals program--through snack bars and vending machines--has pretty much canceled out the benefits of all those efforts. Federal rules that govern the sales of these harmful foods at school are limited and have not been updated for nearly 40 years. Until new regulations are written, children who are served healthy meals in the school cafeteria will continue to buy candy drinks and high sodium snacks elsewhere in school. Many states' school districts have taken positive steps, but others are likely to resist, especially districts that sell junk food to finance athletic program extracurricular activities, and even copier expenses. Those districts should take note of a study released in 2009 in West Virginia showing that the budgetary costs of switching from sodas to healthy drinks such as fruit juice, milk, and water were very little. Even if the switch costs money, so be it. The school should not be trading their students' health to buy office supplies. Over the last five decades, the obesity rates for adolescents have tripled. Unless there is decisive action, weight and inactivity-related disorders will bother a steady larger proportion of the work force and replace smoking as the leading cause of premature death.
Answer: high calorie snacks

Ex Output:
According to this passage, _ are to blame for the childhood obesity.

Article: Leaders of the World Health Organization say they are concerned about the air quality and health efiects on citizens during a recent outbreak of heavy pollution in Beijing.Still,they said they were unsure of the exact amount the air pollution takes on any person's body,casting doubts on local reports tying the area's dirty air to particular cases of illness. Speaking at a briefing on Tuesday,the WHO's Western Pacific regional director, Shin Young--Soo,cited reports about poor air quality causing lung cancer in recent weeks. "The WHO is skeptical of the information,"she said."We're cautious of whether the illness is related to air po11ution. We know it has an impact on health,but we don't know how much." The officials didn't cite particular reports.The comments follow a number of articles since late last year connecting some cases of diseases like lung cancer with pollution,.including one in November regarding an 8-year-old girl. The health impact of Beijing's gray skies has been on the minds of many over the past week. Local authorities on Tuesday preserved an orange alert the city's second highest pollution-warning level--and again warned people to stay indoors.Experts widely agree that small particulates known as PM2.5 carry significant short-and long-term health risks,particularly with children.Other studies find a certain link between pollution and shorter life spans. Chinese state media have noted a rise in cancer levels in Beijing,without specifying whether the new cases are the main result of pollution,smoking,other sources or some combination. Bernhard Schwartlander,the organization's China chief,said he is concerned and has been in contact with national authorities."There is no easy solution,"Dr. Schwartlainder said,adding that solving the problem requires managing industry and the economy.WHO leaders advised citizens.to stay indoors and limit exposure to the harmful particulates.When asked if wearing a face mask has any proven efficacy in preventing health effects of air pollution,Dr. Schwartlainder said,"Whatever you do,it's better than nothing."
Answer: in case of an orange alert, we had better not go outside
