Input: Consider Input: Question: Was Montana the quarterback during each of Walsh's Super Bowl wins? Passage:Walsh first developed what would become the West Coast offense when he was offensive coordinator of the Cincinnati Bengals, working under legendary head coach Paul Brown. However, Walsh truly perfected this strategy as the head coach of the San Francisco 49ers. His teams were led by quarterback Joe Montana. Montana, who was noted for his ability to remain calm under pressure, also possessed good mobility and an accurate passing arm. Another important player in the 49ers offense was Roger Craig, a swift, speedy running back who could also catch passes out of the backfield and was a good receiver. Walsh's 49ers teams also featured several All-Pro wide receivers, including Dwight Clark, John Taylor, and Jerry Rice. The 49ers were one of the NFL's powerhouses in the 1980s and 1990s, under the guidance of head coaches Bill Walsh (1979–1988) and George Seifert (1989–1996). Walsh won three Super Bowls in the 1981, 1984 and 1988 seasons. Seifert won two Super Bowls in 1989 and 1994. Montana, Walsh and Rice are in the Pro Football Hall of Fame, and so is Montana's successor, quarterback Steve Young. Like Montana, Young was a great running quarterback and a very efficient passer.

Input: Consider Input: Question: How many years did Nick Van Exel play for the Nuggets? Passage:The 1998–99 NBA season was the Nuggets' 23rd season in the National Basketball Association, and 32nd season as a franchise. During the offseason, the Nuggets acquired Nick Van Exel from the Los Angeles Lakers, and second-year guard Chauncey Billups from the Toronto Raptors. Despite the return of Antonio McDyess, who was re-signed by the team after one season with the Phoenix Suns, the Nuggets continued to struggle under new head coach Mike D'Antoni losing eight of their first nine games. Top draft pick Raef LaFrentz out of Kansas was out for the remainder of the season with a knee injury after playing just twelve games. The Nuggets finished the lockout shortened season sixth in the Midwest Division with a 14–36 record. This was also their final season playing at McNichols Sports Arena. Following the season, second-year forward Danny Fortson and Eric Williams were both traded to the Boston Celtics, and D'Antoni was fired as coach.

Input: Consider Input: Question: Which of the groups that formed a coalition agreement in 2006 had more members? Passage:After the Dutch general election of 2006 the Labour Party, Christian Democratic Appeal (CDA) and the ChristianUnion (CU) formed a coalition agreement which resulted in the formation of the Cabinet Balkenende IV. Timmermans became Undersecretary for Foreign Affairs and was responsible for the co-ordination of government policy towards the European Union, and was conferred the diplomatic title of Minister of European Affairs during international visits. A major theme of his time as Undersecretary for European Affairs was to increase support for European integration. This was done both by seeking greater influence of citizens on European policies and by improving communication and public perception; besides citizens the aim was that education should have also be more involved with Europe. The Treaty of Lisbon was signed whilst he was Undersecretary, before which Timmermans and Prime Minister Jan Peter Balkenende successfully lobbied to secure a greater role for national parliaments in European Union decision-making processes. In February 2010, NATO officially requested the Netherlands to extend its military involvement in Task Force Uruzgan. The Labour Party strongly opposed the extension of the mission and on 23 February 2010 the Cabinet Balkenende IV fell after the Labour Party officially withdrew its support with all Labour Party Cabinet members resigning.
