In this task, you will be presented with a context passage, a question about that paragraph, and a possible answer to that question. The task is to check the validity of the answer. Answer with "Yes" or "No".

Ex Input:
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. <sep>How long ago was Springfield, Illinois covered by over a mile of ice?<sep>1,200 years ago

The National Security Act of 1947 created the position of Director of Central Intelligence (DCI). Independent from the departments of Defense, State, Justice, and other policy departments, the DCI heads the U.S.intelligence community and provides intelligence to federal entities. The sole element of the intelligence community independent from a cabinet agency is the CIA. As an independent agency, it collects, analyzes, and disseminates intelligence from all sources. The CIA's number one customer is the president of the United States, who also has the authority to direct it to conduct covert operations. Although covert actions represent a very small fraction of the Agency's entire budget, these operations have at times been controversial and over time have dominated the public's perception of the CIA. The DCI is confirmed by the Senate but is not technically a member of the president's cabinet. The director's power under federal law over the loose, confederated "intelligence community" is limited. He or she states the community's priorities and coordinates development of intelligence agency budget requests for submission to Congress. This responsibility gives many the false impression that the DCI has line authority over the heads of these agencies and has the power to shift resources within these budgets as the need arises. Neither is true. In fact, the DCI's real authority has been directly proportional to his personal closeness to the president, which has waxed and waned over the years, and to others in government, especially the secretary of defense. Intelligence agencies under the Department of Defense account for approximately 80 percent of all U.S. spending for intelligence, including some that supports a national customer base and some that supports specific Defense Department or military service needs. As they are housed in the Defense Department, these agencies are keenly attentive to the military's strategic and tactical requirements. <sep>Who coordinates development of intelligence agency budget requests for submission to Congress?<sep>Director of Central Intelligence

(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. <sep>Who said they would quit as party leader of DPJ?<sep>Natashi Oguawa
