Question: What is the nickname of the city where the cigarette brand that sponsored the Benetton B194 prior to the 1994 Formula One season?
Context: Mayfair is a brand of cigarettes, produced by the Gallaher Group division of Japan Tobacco.  The brand is available in seven versions; Fine King Size, King Size, King Size Smooth, Menthol, Superkings, Superkings Menthol and Superkings Smooth.  Gallaher launched Mayfair in 1992, with the slogan "A good smoke at a fair price".  The brand is Gallaher Group's leading value cigarette brand.  Mayfair is one of the least expensive cigarette brands in the U.K., despite its name presumably being chosen to evoke the glamour of Mayfair, the famous London district.  By 2007 Mayfair had become the second most popular cigarette brand in the U.K., with total sales of £663 million. The Lotus E23 Hybrid is a Formula One racing car which Lotus used to compete in the 2015 Formula One season.  It was driven by Romain Grosjean and Pastor Maldonado.  This was the team's only car to use Mercedes engines, after a 20-year partnership with Renault.  The E23 Hybrid was also the first Enstone-based car to be powered by other than a Renault engine since the Ford-powered Benetton B194 in . The Benetton B195 was a Formula One car designed by Rory Byrne and Ross Brawn for use by Benetton in the 1995 Formula One season.  The B195 was similar to its B194 predecessor, but a change of engine supplier from Ford to Renault caused a redesign of the engine installation, gearbox and rear suspension.  The car was now powered by a Renault V10 engine of the same type the rival Williams team were using in their FW17.  The B195 was not as stable as the FW17 and was seen by most paddock insiders as inferior to its rival.  When Gerhard Berger came from Ferrari to Benetton in late 1995 during winter testing, he found the balance of the car very poor, and Schumacher made the comment: "If he had driven the car at the beginning of the season, he would have spun in the pit-lane!" Embassy Hill was a short-lived Formula One team started by the two-time Formula One world-champion Graham Hill, racing as a constructor with its own chassis in .  The team debuted in and had limited success in three seasons of racing, but everything was cut short by the death of Hill, Tony Brise and some of the team's top personnel in the crash of a light aircraft in the autumn before the season.  The team was sponsored by Imperial Tobacco's Embassy cigarette brand and ran under various names during its time. The 1994 Formula One cheating controversy was a series of allegations made throughout the 1994 Formula One season.  Several Formula One teams were involved, with the main allegations surrounding Benetton Formula.  Initially, Benetton were alleged to have been using illegal software—namely traction control—to their advantage in races; however, this could not be sufficiently proven by the FIA.  A refuelling fire on Jos Verstappen's Benetton car at the German Grand Prix led to renewed allegations and an investigation by Intertechnique at Benetton's team factory.  Following the investigation, the Fédération Internationale de l'Automobile (FIA) revealed Benetton had been using an illegal fuel valve without a fuel filter that allowed fuel into the car 12.5% faster than a legal fuel valve. Camel is a brand of cigarettes that was introduced by American company R.J. Reynolds Tobacco in 1913.  Most current Camel cigarettes contain a blend of Turkish tobacco and Virginia tobacco.  Winston-Salem, North Carolina, the city where R.J. Reynolds was founded, is nicknamed "Camel City" because of the brand's popularity. The 1994 Canadian Grand Prix was a Formula One motor race held on 12 June 1994 at the Circuit Gilles Villeneuve in Montreal, Quebec, Canada.  The 69-lap race was the sixth round of the 1994 Formula One season and the 32nd Canadian Grand Prix.  The race was won by Benetton driver Michael Schumacher, who took his fifth victory of the season and extended his lead in the drivers' standings to 33 points.  Damon Hill and his team, Williams, were second in their respective championships, as well as second in the race, and were Schumacher and Benetton's main rivals over the season.  Jean Alesi completed the podium by finishing in third place for Ferrari. The Benetton B194 was designed by Rory Byrne for the 1994 Formula One season.  The car was closely based on the previous Benetton B192/3 and powered by a Ford Zetec-R V8 engine (produced by Cosworth but funded by and badged as a Ford).  It featured Mild Seven sponsorship for the first time, which was then carried on until the end of tobacco sponsorship in F1, replacing Camel as their main sponsor.  The electronic driver aids that had had such an effect on F1 over the previous seasons were banned, so the car had to be redesigned with the new rules in mind.  The B194 was a light and nimble car that handled well and was most competitive in the hands of Schumacher on twisty tracks unlike the early Williams FW16 which proved difficult to drive thanks to Williams's dependence on electronic driving aids in the previous season.  Michael Schumacher's B194 remained the most competitive driver/car combination until Williams introduced a B-spec car at the German Grand Prix. The 1994 Japanese Grand Prix (formally the XX Fuji Television Japanese Grand Prix) was a Formula One motor race held on 6 November 1994 at the Suzuka Circuit, Suzuka.
