Q: In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Question: Which is the oldest team that the 1985 Bears shut out during the playoffs? Passage 1: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.
 Passage 2:A large expansion of the state highway system in 1933 resulted in Route 56 being extended in both directions. To the south, a second section was added, beginning at Pismo Beach on US 101 (Route 2) and heading south through Guadalupe and Lompoc to rejoin US 101 at a junction called Los Cruces (sic), just north of Gaviota Pass. (A short piece near Orcutt and Los Alamos had been part of Route 2, which originally followed present SR 135 from Los Alamos to Santa Maria.) To the north, Route 56 was continued along the coast from Carmel through Santa Cruz to San Francisco. Several discontinuous pieces were added north of San Francisco, one from Route 1 (US 101) north of the Golden Gate to the county line near Valley Ford, another from the Russian River near Jenner (where the new Route 104 ended) to Westport, and a third from Ferndale to Route 1 near Fernbridge. Except for the gaps in Route 56 north of San Francisco, these additions completed the coastal highway, with other sections formed by Routes 1, 2, and 71.
 Passage 3:The Turkel Commission (officially The Public Commission to Examine the Maritime Incident of 31 May 2010) is an inquiry set up by Israeli Government to investigate the Gaza flotilla raid, and the Blockade of Gaza. It is led by Israeli retired Supreme Court Judge Jacob Turkel. The other initial members of the commission were former President of the Technion and military expert, Amos Horev, and professor of international law, Shabtai Rosenne, who died in September 2010. The probe was overseen by two International observers: William David Trimble, former Leader of the Northern Irish Ulster Unionist Party and Northern Irish First Minister, a Nobel Peace Prize laureate, and Canadian former military judge Ken Watkin.
