Question: How many months/years passed between the signing of the Adams-Onis Treaty and the acquisition of Florida? Passage:Born in Braintree, Massachusetts, Adams spent much of his youth in Europe, where his father served as a diplomat. After returning to the United States, Adams established a successful legal practice in Boston. In 1794, President George Washington appointed Adams as the U.S. ambassador to the Netherlands, and Adams would serve in high-ranking diplomatic posts until 1801, when Thomas Jefferson took office as president. Federalist leaders in Massachusetts arranged for Adams's election to the United States Senate in 1802, but Adams broke with the Federalist Party over foreign policy and was denied re-election. In 1809, Adams was appointed as the U.S. ambassador to Russia by President James Madison, a member of the Democratic-Republican Party. Adams held diplomatic posts for the duration of Madison's presidency, and he served as part of the American delegation that negotiated an end to the War of 1812. In 1817, newly-elected President James Monroe selected Adams as his Secretary of State. In that role, Adams negotiated the Adams–Onís Treaty, which provided for the American acquisition of Florida. He also helped formulate the Monroe Doctrine, which became a key tenet of U.S. foreign policy.

Question: Who did the Bears defeat in their 1963 Super Bowl win? Passage:The Bears won fifteen games, as the 49ers had the year before, and won their first twelve before losing to the Miami Dolphins to deny a perfect season. The Bears' defense was ranked first in the league and only allowed 198 total points (an average of 12.4 points per game). The Bears won the NFC Central Division by seven games over the second place Green Bay Packers and earned the NFC's top seed and home field advantage throughout the playoffs at Soldier Field. In their two playoff games against the New York Giants and Los Angeles Rams, the Bears outscored their opponents 45–0 and became the first team to record back-to-back playoff shutouts. Then, in Super Bowl XX in New Orleans against the New England Patriots, the Bears set several more records. First, their 46 points broke the record that had been set by the Los Angeles Raiders in 1984 with 38 and tied by the 49ers the following year. Their 36-point margin of victory topped the 29-point margin of victory that the Raiders had put up in Super Bowl XVIII and stood as a record until the 49ers won Super Bowl XXIV, also in New Orleans, by 45 points over the Denver Broncos. It was the Bears' first NFL World Championship title since 1963.

Question: How long was the ship that Dashwood was appointed captain of on August 14th, 1812? Passage:Afterwards Dashwood took eight American merchantmen, and on 15 June 1812, he captured the Hope, a merchant ship off the north of Gothland. On 14 August 1812 he was appointed captain of HMS Cressy of 74 guns, and given a piece of plate by the officers of HMS Pyramus. After serving in the North Sea under Admiral Sir William Young, Dashwood escorted a convoy to the West Indies, whence he returned with another of equal importance. At the review of the fleet at Spithead, in the summer of 1814, he steered the Royal barge. Afterwards he took part, commanding HMS Norge of 74 guns, in the Battle of New Orleans, where he assisted Admiral Pulteney Malcolm in the debarkation of the army, being reported by Sir Alexander Cochrane. He was also present at the Battle of Lake Borgne, where a few gunboats of the Norge, in company with other small vessels, captured five American gunboats. In 1815, when at anchor in Port Royal, his ship was struck by lightning, which broke the main-topgallant-mast in three pieces, shivered the maintop-mast and brought the mizentop-mast and topgallant-mast down on to deck. In 1821 he was given command of HMS Windsor Castle of 74 guns, and HMS Impregnable, of 104 guns, as Cochrane's flag-captain. He recommissioned Windsor Castle on 4 January 1822, as part of the guard-ships in Hamoaze. In 1825 he was put onto half-pay, and was made a rear-admiral on 22 July 1830. He assumed the rank of vice-admiral on 23 November 1841. Charles died while at service, on 21 September 1847. Consequently, on 22 September 1847, the Admiralty promoted him posthumously to the rank of admiral.
