Input: Consider Input: Question: How old is the team that beat the 1985 Bears? 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.

Input: Consider Input: Question: Which state is Albert P. Laning a Senator for? Passage:The caucus of Democratic State legislators met on January 15, State Senator Albert P. Laning, of Buffalo, presided. All but one of the legislators were present, only Assemblyman John M. Roscoe, of Schoharie County, was sick. The caucus nominated Francis Kernan for the U.S. Senate. Kernan had been the Democratic/Liberal Republican candidate for Governor in November 1872 but had been defeated by John Adams Dix. Now Kernan was the choice of Tammany boss John Kelly who had succeeded the corrupt William M. Tweed. Kelly was opposed by John C. Jacobs, who proposed Ex-State Senator Henry C. Murphy, Jacobs's predecessor from the 3rd District, and the Democratic candidate who had lost the U.S. Senate elections in 1867 and 1869 when the Democrats were the minority. Kelly stood firm in his intention to dominate the Democratic Party, and had the caucus nomination made by viva voce vote instead of the more traditional secret ballot. Jacobs and Murphy had expected to get votes from many legislators who would not dare to cross Kelly openly, but had to abandon their hopes when the secret ballot was voted down 74 to 13.

Input: Consider Input: Question: How many albums total did the Beatles record in Hamburg? Passage:Ain't She Sweet was an American album featuring four tracks recorded in Hamburg in 1961 by The Beatles featuring Tony Sheridan (except for the title song with vocal by John Lennon) and cover versions of Beatles and British Invasion-era songs recorded by the Swallows. As Atlantic Records only had rights to four Sheridan/Beatle recordings recorded by Polydor Records, they filled the rest of the album with Beatle and British Invasion cover songs. When this material was released by Atco Records, there were mono (catalogue number 33-169) and stereo (SD 33-169) editions. Atco also added additional drum overdubs to the four Sheridan cuts on top of the original drum tracks. American drummer Bernard Purdie claims to have performed overdubs of unspecified Beatles records, which would most likely have been for Ain't She Sweet, but this has never been officially confirmed.
