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 450 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: How large was the endowment at Durham University the year that Mitchell started attending the school? Passage:Mitchell was born in London, and educated at Brightlands Preparatory School and Dulwich College, London. In 1943 he registered as a conscientious objector and his war-time service was spent in the Non-Combatant Corps. After the war, he taught at Oakfield Preparatory School, London and in 1947 founded and edited the journal Music Survey; several issues appeared before he was joined in 1949 by Hans Keller and the journal was re-launched in the Music Survey's so-called 'New Series' (194952), whose uncompromising critical standards and pugnaciously pro-Britten and pro-Schoenberg stance brought it renown and notoriety in equal measure. Mitchell studied at Durham University 1949-50. In the 1950s he was a regular contributor to the journals Musical Times and Musical Opinion. In 1958 he became editor of Music Books at Faber and Faber and in the same year was appointed Editor of Boosey & Hawkes's music journal Tempo, until 1962. From 1963 to 1964 he was a special music adviser at Boosey & Hawkes with particular responsibility for contemporary music and the acquisition of contemporary composers. He was responsible for Peter Maxwell Davies and Nicholas Maw joining the publisher's list. In 1965, with the encouragement of Benjamin Britten he founded the music-publishing firm of Faber Music, and was its first Managing Director (vice-chairman, 1976, chairman, 1977, president, 198895). In 1972 he became the first Professor of Music at Sussex University (until 1976). Following the death of Benjamin Britten, Mitchell became a senior trustee of the Britten-Pears Foundation; in 1986 he became the Foundation's director and chairman of the Britten Estate Ltd. From 1989 to 1992 he was chairman of the Performing Right Society. He was appointed a CBE in the 2000 New Year Honours, and died on 28 September 2017.
