Question: Who was the CEO of the company that Leaton got a paid internship with in 2006? Passage:He won significant critical attention in 2006 when he was awarded the grand prize of the 2006 Film Your Issue competition, judged by President Barack Obama, George Clooney and the Dalai Lama, among others. Leaton presented his winning film Orphans in Africa and gave acceptance speeches, covered by the press, at three awards ceremonies: at the United Nations Headquarters where he was introduced by the President of USA Today, then again in Hollywood where he was introduced by the Mayor of Los Angeles, and finally during Sundance in Park City with Kevin Bacon and Mandy Moore. Leaton also received the 2006 grand prize Walt Disney Pictures paid internship. His mentors included some of the top executives, and he began getting hands-on experience on various Disney films. Years later when Lindsey Brookbank of the Collegiate Times asked him what his favorite memory was from his grand-prize internship, he replied "Having dinner with Roy Disney on board the Queen Mary." According to Brookbank, this internship gave Leaton the connections and experience that would help him land jobs in Hollywood after finishing college. He returned to Film Your Issue as a member of the jury the following year, and has also judged other student film contests.

Question: How long did the Siege of Boston last? Passage:The Battle of Lexington and Concord was the first conflict in the American Revolutionary War. On April 19, 1775, a force of British Army regulars marched from Boston to Concord to capture a cache of arms that was reportedly stored in the town. Forewarned by Samuel Prescott (who had received the news from Paul Revere), the colonists mustered in opposition. Following an early-morning skirmish at Lexington, where the first shots of the battle were fired, the British expedition under the command of Lt. Col. Francis Smith advanced to Concord. There, colonists from Concord and surrounding towns (notably a highly drilled company from Acton led by Isaac Davis) repulsed a British detachment at the Old North Bridge and forced the British troops to retreat. Subsequently, militia arriving from across the region harried the British troops on their return to Boston, culminating in the Siege of Boston and the outbreak of the war.
