Question: Article: A rising population is one of the main reasons that there is global warming. Between 1650 and 1850 the population increased by 0.75 billion people going from 0.25 billion to one billion. From 1930 to the end of the century the population rose from two billion to over six billion. In just a third of the time the population rose by more than five times what it did before. It is expected that this trend in the changing population will continue and could even heighten. The growing population requires increasing amounts of energy. These energy demands and other supplies require production, which almost always involves the emission of greenhouse gases. The more the population increases the more greenhouse gases that are produced and the greater the increase in temperature. The burning of fossil fuels is one of the best-known causes for global warming. The major reason for fossil fuels contributing so much to global warming is the release of carbon that occurs during the burning of fossil fuels. When people burn fossil fuels, they release large amounts of carbon by way of the release of carbon dioxide. The carbon dioxide in the air then leads to global warming. Another source of carbon dioxide comes from _ . In forests there is a large amount of carbon that is stored in the trees and other plants. This carbon is out of the atmosphere because the trees consume the carbon from carbon dioxide. When people cut down trees, they are frequently burned. This burning releases the carbon dioxide into the atmosphere that was stored in organic matter. Even when new trees are planted, it can take up to one hundred years to make up for the carbon that was released. It is commonly thought that because trees absorb more carbon dioxide, the atmosphere experiences positive effects. Sophie Armstrong, the writer of Earth Care put it, "There's no doubt that the earth is becoming warmer because of human activity rather than a random but natural phenomenon.
Answer: Carbon Dioxide

Question: Article: Forty years ago, Finland was a small, country with mediocre public schools. Today, Finland is still small but no one calls Finland's public schools mediocre any more. In 2000, the Finns surprised the world when their 15-year-olds scored at the top of a closely watched international exam called the PISA. Finland has stayed near the top ever since, while the U.S. scores around the middle. Pasi Sahlberg, an official with Finland's Ministry of Education and Culture, is in Seattle this week to share the story of Finland's success, and what states like Washington can learn from it. Sahlberg's message, although he is too polite to put it so bluntly: Stop testing so much, trust teachers more; give less homework; shorten the school day. On Tuesday, in a room filled with teachers, principals, professors, school-board members and policy makers, Sahlberg joked about the Finns' reputation for being a quiet, humble people. "When Finland hit the top of the PISA," he said, "the biggest disbelievers were Finns." More seriously, Finland never set out to create the world's top school system. Instead, he said, the country decided in the 1970s that it wanted to ensure that a student's success didn't depend on family background. "Finland relied on cooperation among teachers and schools, rather than on competition. Rather than judging teachers and schools based on test scores," he said, "Finland puts trust in its teachers and principals. Teachers develop the curriculum in Finland, and design their own tests. There are no national tests, except one at the end of high school." That's just the start. Along with a shorter school day, Finnish students don't even start school until they are 7 years old. Many primary schools have a policy against giving homework. "But Finland," he said, " succeeded in part by adopting ideas from the U.S. and other countries. And those countries, he said, can learn from Finland, too."
Answer: To ask the US to improve its education.

Question: Article: The Cuban iguana is a species of lizard of the iguana family. It is the largest of the West Indian rock iguanas, one of the most endangered groups of lizards. This species with red eyes and a thick tail is one of the largest lizards in the Caribbean. The Cuban iguana is mainly _ : 95% of its diet consists of the leaves, flowers and fruits from as many as 30 plant species, including the seaside rock bush and various grasses. However, Cuban iguanas occasionally eat animal matter, and individuals have been watched eating the dead flesh of birds, fish and crabs. The researchers wrote that quite a few people on Isla Magueyes could have caused this incident. The Cuban iguana is living throughout the rocky southern coastal areas of mainland Cuba and its surrounding islands with a wild population growing rapidly on Isla Magueyes, Puerto Rico. It is also found on the Cayman Islands of Little Cayman and Cayman Brac, where a separate subspecies occurs. Females guard their nest sites and often nest in sites half destroyed by Cuban crocodiles. To avoid the attack from them, the Cuban iguana often makes its home within or near prickly-pear cacti . In general the species is decreasing, more quickly on the mainland than on the outlying islands. One of the reasons for their decrease is habitat destruction caused by the over consuming of farm animals, housing development, and the building of tourist resorts on the beaches where the animals prefer to build their nests. Although the wild population is decreasing, the numbers of iguanas have been sharply increased as a result of captive-breeding and other protection programs.
Answer: Three.
