Question: Williams drivers finished first and second in the 1992 Brazilian Grand Prix at Interlagos. Who won this race on his way to becoming 1992 Formula One World Champion?
Context: The 2004 Brazilian Grand Prix was a Formula One motor race held on 24 October 2004 at the Autódromo José Carlos Pace.  It was the final race of the 2004 season and the first time that a GP in Brazil was not one of the first three rounds of an F1 season, and local fans were delighted when Brazil's Rubens Barrichello took pole for his home race.  It would be Barrichello's first non-retirement at Interlagos in ten years, his previous finish at the circuit being at the season opener in 1994.  The early laps were held in changeable conditions, and the race ended up as a duel between Kimi Räikkönen and Juan Pablo Montoya, who were to be McLaren team-mates for 2005.  The Colombian took victory in his final race for Williams, which was also the last win for the Williams team until the 2012 Spanish Grand Prix.  Montoya's move to take the lead was brave even by his standards.  Elsewhere, Jaguar's final race was a failure of epic proportions, with their two drivers colliding, with Webber trying an optimistic-looking move on Klien whilst expecting his team-mate to move over. The 1992 Brazilian Grand Prix (formally the XXI Grande Prêmio do Brasil) was a Formula One motor race held at Interlagos on 5 April 1992.  It was the third round of the 1992 Formula One season.  The 71-lap race was won by Williams driver Nigel Mansell after he started from pole position.  His teammate Riccardo Patrese finished second and Michael Schumacher took third for the Benetton team. The 1973 Brazilian Grand Prix was a Formula One motor race held at Interlagos on February 11, 1973.  It was race 2 of 15 in both the 1973 World Championship of Drivers and the 1973 International Cup for Formula One Manufacturers.  It was also the first ever world championship race to be held in Brazil.  The race was won by home town hero Emerson Fittipaldi after starting from first row beside Ronnie Peterson, who claimed the first pole position in his Formula One career, both driving Lotus.  Jackie Stewart finished in second position, driving a Tyrrell.  Denny Hulme finished in third position, driving a McLaren. The 1992 Belgian Grand Prix was a Formula One motor race held at Spa-Francorchamps on 30 August 1992.  It was the twelfth round of the 1992 Formula One season.  The race was won by Benetton's Michael Schumacher, the first of his record 91 Grand Prix wins.  The Benetton B192's win also marks the last F1 win of Grand Prix car with an H-Pattern manual gearbox.  Second and third for Williams drivers Nigel Mansell (who survived a collision with Jean Alesi at the first corner) and Riccardo Patrese secured for the team their first Constructor's title since 1987. The 1980 Brazilian Grand Prix was a Formula One motor race held on 27 January 1980 at the Interlagos circuit in the Interlagos neighborhood of São Paulo.  It was the second round of the 1980 Formula One season, and it was also the ninth Brazilian Grand Prix.  It was the eighth to be held at Interlagos and would be the last until the circuit was substantially redeveloped for the 1990 Brazilian Grand Prix.  The race was held over 40 laps of the 7.87-kilometre circuit for a total race distance of 315 kilometres.  This race was originally supposed to be held at the Jacarepaguá circuit in Rio de Janeiro, but was transferred to Interlagos because parts of the Rio circuit's tarmac were actually sinking into the soft swampland the circuit was built on.  This last-minute switch to Interlagos- which was to be resurfaced and heavily rebuilt with new pit facilities and safety measures for the 1981 season caused a lot of controversy- Interlagos had returned a bit too soon for some of the drivers. The 1990 Brazilian Grand Prix was a Formula One motor race held on 25 March 1990 at Interlagos.  It was the 19th Brazilian Grand Prix and the ninth to be held at Interlagos.  The São Paulo circuit had not held the Grand Prix since 1980 and the circuit was extensively renovated with the circuit itself almost halved in length.  The race was contested over 71 laps of the four kilometre circuit (as opposed to 40 for the races on the original circuit), for a race distance of 307 kilometres. Nigel Ernest James Mansell, {'1': ", '2': ", '3': ", '4': "} ( ; born 8 August 1953) is a British former racing driver who won both the Formula One World Championship (1992) and the CART Indy Car World Series (1993).  Mansell was the reigning F1 champion when he moved over to CART, becoming the first person to win the CART title in his debut season, and making him the only person to hold both the World Drivers' Championship and the American open-wheel National Championship simultaneously. The 1976 Brazilian Grand Prix was a Formula One motor race held at Interlagos in São Paulo, Brazil on 25 January 1976.  It was the opening round of the 1976 Formula One season.  The race was the fifth Brazilian Grand Prix and the fourth to be held for the World Drivers' Championship.  The race was held over 40 laps of the 7.87-kilometre circuit for a total race distance of 315 kilometres. The 2014 Australian Grand Prix (formally known as the 2014 Formula 1 Rolex Australian Grand Prix) was a Formula One motor race that was held on 16 March 2014 in Melbourne.  The race was contested over 58 laps of the Melbourne Grand Prix Circuit and was the first round of the 2014 FIA Formula One World Championship.  It marked the début of new Formula One regulations which introduced 1.6 litre turbocharged V6 engines to the sport; the first such instance, since the 1988 Australian Grand Prix, that turbocharged engines have been used in Formula One.  It was the seventy-ninth race in the combined history of the Australian Grand Prix—which dates back to the 100 Miles Road Race of 1928—and the nineteenth time the event was held at the Melbourne Grand Prix Circuit.  The race also marked the thirtieth year that the Australian Grand Prix was run as a round of the Formula One World Championship. The 1975 Brazilian Grand Prix was a Formula One motor race held at Interlagos on 26 January 1975.  It was race 2 of 14 in both the 1975 World Championship of Drivers and the 1975 International Cup for Formula One Manufacturers.  It was the fourth Brazilian Grand Prix since its introduction in 1972.  The race was won by São Paulo native Carlos Pace driving a Brabham BT44B.  It was the only win of Pace's career; he was killed in an aircraft accident two years later.  The circuit now holds his name.  It would be eight years before another Brazilian would win the Grand Prix.  Fellow Brazilian Emerson Fittipaldi finished second in his McLaren M23 with his German team mate Jochen Mass finishing third.
