Example Input: Article: The Dangers of Dieting Thanks to our modern lifestyle, with more and more time spent sitting down in front of computers than ever before, the number of overweight people is at a new high. As people crazily search for a solution to this problem, they often try some of the popular fad diets being offered. Many people see fad diets as harmless ways of losing weight, and they are grateful to have them. Unfortunately, not only don't fad diets usually do the trick, but they can actually be dangerous for your health. Although permanent weight loss is the goal, few are able to achieve it. Experts estimate that 95 percent of dieters return to their starting weight, or even add weight. While the irresponsible or unwise use of fad diets can bring some initial results, long-term results are very rare.[:**] Nonetheless, people who are bored with the difficulties of changing their eating habits often turn to fad diets. Rather than being moderate, fad diets involve extreme dietary changes. They advise eating only one type of food, or they prohibit other types of foods entirely. This results in a situation where a person's body doesn't get all the vitamins and other things that it needs to stay healthy. One popular fad diet recommends eating lots of meat and animal products, while nearly eliminating carbohydrates . A scientific study from Britain found that this diet is very high in fat. According to the study, the increase of damaging fats in the blood can lead to heart disease and, in extreme cases, kidney failure. Furthermore, diets that are too low in carbohydrates can cause the body to use its own muscle for energy. The less muscle you have, the less food you use up, and the result is slower weight loss. Veteran dieters may well ask at this point, "What is the ideal diet?" Well, to some extent, it depends on the individual. A United States government agency has determined that to change your eating habits requires changing your psychology of eating, and everyone has a different psychology. That being said, the British study quoted above recommends a diet that is high in carbohydrates and high in fiber, with portions of fatty foods kept low. According to the study, such a diet is the best for people who want to stay healthy, lose weight, and keep that weight off. And, any dieting program is best undertaken with a doctor's supervision.
Answer: They gain the weight back again.
Example Output: After losing weight by dieting, what usually happens to people?

Example Input: Article: Researchers and many scientists are concerned that the earth's climate and atmosphere are becoming warmer than they should be. What scientists do agree on is that the temperature will continue to increase if measures are not taken to reduce pollution and emission from cars and factories. It is widely agreed that oil and coal create greenhouse gases when they are burned to produce heat or power. These emissions include carbon dioxide, which is the cause of most of the global warming problem. The loss of the trees in many areas is making the problem worse, because trees and plants absorb carbon dioxide and release oxygen. The fewer trees that are left standing, the less carbon dioxide can be absorbed. Scientists predict that the sea level will rise, ice caps will melt, and some animals and plants will fail to survive because their habitat will disappear. There may be more deserts and less available farmland because of the dry ground, and there may be more storms and floods in many countries. Some countries, including the UK and the US, are taking steps to prevent the situation from becoming worse. There are programmes to educate citizens and students about the situation and recycling waste is becoming more common. New guidelines are being introduced to try to limit greenhouse gases from being produced by factories and businesses. Using more alternative energy sources is also a good way to prevent global warming. One thing that everyone can do is limit their use of energy every day, and you can do this no matter how old or young you are. Try to limit the unnecessary use of electricity and work to conserve energy every day.
Answer: No Emissions, No Warming
Example Output: What is the best title for the text?

Example Input: Article: Travelling around the world with children is difficult enough, but attempting it without using motorized transport is even more of challenge. But Dario Schworer, a 42-year-old climatologist and mountain guide, and his 33-year-old wife Sabine are on a journey to do just that. The Swiss couple want to travel across the world's oceans and climb the highest mountain on every continent to promote Earth-friendly ways of life. "We are collecting good examples of dealing with climate change and living in harmony with nature and we want to spread such ideas," Schworer said. "We want to help people affected by global warming and to inspire children for the future." Recently after having spent three months teaching children in the Everest region, the couple want to show it is possible to travel through as the world's climate zones using just human-power and forces of nature. In the 47 countries they have visited so far they have collected 22 tons of trash, taught people in Ecuador how the sun's rays can be used to clean water and inspired a person in Chile to build a house on water with recycled plastic bottles as a foundation. They have also collected trash in the mountains of Nepal with school children. So far they have communicated with 45,000 children from South America, Australia and Asia, giving presentations about the importance of recycling and using alternative energy like solar and wind power. "We need to motivate children," said Sabine. When they began their adventure in 2003 they had no children of their own. But since then two has become five: daughter Sabine is now five years old, Andri was born in Chile and baby Noe was born in Australia. _ the couple thought they would complete their travels in four years, but now, seven years later, they believe it could take seven more. "Since our belief is the need to respect nature, we travel only when conditions are good," Schworer said.
Answer: To promote Earth-friendly ways of life.
