Imagine you are standing in a farm field in central Illinois. The land is so flat you can see for miles and miles. On a clear day, you might see a grain silo 20 miles away. You might think to yourself, it sure is flat around here. If you drive one hundred miles to the south, the landscape changes. In southern Illinois, there are rolling hills. Why do you think this is? What could have caused these features? There are no big rivers that may have eroded and deposited this material. The ground is capable of supporting grass and trees, so wind erosion would not explain it. To answer the question, you need to go back 12,000 years. Around 12,000 years ago, a giant ice sheet covered much of the Midwest United States. Springfield, Illinois, was covered by over a mile of ice. Its hard to imagine a mile thick sheet of ice. The massive ice sheet, called a glacier, caused the features on the land you see today. Where did glaciers go? Where can you see them today? Glaciers are masses of flowing ice.

Soon after the conclusion of peace, important changes were made in legislation concerning industry and commerce, and the new freedom thus afforded produced a large number of limited liability companies. Plans were formed for building a great network of railways, partly for the purpose of developing the natural resources of the country, and partly for the purpose of increasing its power for defense and attack. The existence of serfdom was tackled boldly, taking advantage of a petition presented by the Polish landed proprietors of the Lithuanian provinces and, hoping that their relations with the serfs might be regulated in a more satisfactory way (meaning in a way more satisfactory for the proprietors), he authorized the formation of committees "for ameliorating the condition of the peasants," and laid down the principles on which the amelioration was to be effected. This step had been followed by one even more significant. Without consulting his ordinary advisers, Alexander ordered the Minister of the Interior to send a circular to the provincial governors of European Russia (serfdom was rare in other parts), containing a copy of the instructions forwarded to the Governor-General of Lithuania, praising the supposed generous, patriotic intentions of the Lithuanian landed proprietors, and suggesting that perhaps the landed proprietors of other provinces might express a similar desire. The hint was taken: in all provinces where serfdom existed, emancipation committees were formed. The emancipation was not merely a humanitarian question capable of being solved instantaneously by imperial ukase. It contained very complicated problems, deeply affecting the economic, social and political future of the nation. Alexander had to choose between the different measures recommended to him and decide if the serfs would become agricultural laborers dependent economically and administratively on the landlords or if the serfs would be transformed into a class of independent communal proprietors. The emperor gave his support to the latter project, and the Russian peasantry became one of the last groups of peasants in Europe to shake off serfdom. The architects of the emancipation manifesto were Alexander's brother Konstantin, Yakov Rostovtsev, and Nikolay Milyutin. On 3 March 1861, 6 years after his accession, the emancipation law was signed and published.

Problem: When land is cleared, habitats are lost. It may be cleared for agriculture. It may also be used for building new homes or businesses. Within the past 100 years, the amount of land used for agriculture has almost doubled. Land used for grazing cattle has more than doubled. Many wetlands have also been lost to agriculture. The U.S. has lost almost all the natural tall-grass prairies. Thee areas of tall thick grass have virtually disappeared. These areas of land had thick fertile soil. Their grasses had very deep root systems. These deep and thick roots reduced the amount of soil erosion. They also were home to many plants and animals. Prairies were wonderful places. They were home to colorful flowers, prairie dogs, and herds of bison.

Question: "Why do we clear land?"

Answer: "For agriculture"

OPTIONS:
- no
- yes
Answer: yes

(CNN) -- Japan's prime minister conceded defeat in parliamentary elections Sunday, signaling the return to power of the Liberal Democratic Party and ending the brief rule of the disappointing upstart Democratic Party of Japan. Prime Minister Yoshihiko Noda pledged to step down as party president after exit polls showed a smashing loss in lower house voting. The party, once seen as a breath of fresh air in Japanese politics, came to be regarded as increasingly ineffective. "We got a regrettable result," Noda said. "The result is everything in the politics. The biggest responsibility lies on me. I will quit as the partly leader of DPJ." The move clears the way for the return to power of former Prime Minister Shinzo Abe, the current leader of the conservative-leaning Liberal Democratic Party, or LDP. "The Japanese people will be keenly looking whether the LDP can meet with their expectations," Abe said in interviews after the polling. The LDP ruled the country almost continuously since its establishment in 1955 until it was forced from power three years ago by the DPJ. Public broadcaster NHK said the LDP and its coalition partner, the new Komei party, gained at least 302 seats in the 480-seat lower house. CNN's main affiliate, TV Asahi, reports the LDP/Komei coalition gained at least 312 seats. The official count is expected to be released Monday. The LDP is inheriting a struggling economy, regional tensions and questions over Japan's role in Asia. "The economy is at the bottom. It's our first mission to turn it around," Abe said.
