[Q]: Question: How long had the largest wrestling promotion in Mexico been in existence when Guerrera first appeared for them? Passage:The combination of Guerrera's in ring skills, natural charisma and unique mask quickly landed him a regular job working for Empresa Mexicana de Lucha Libre (EMLL), Mexico's largest wrestling promotion. On September 25, 1981 Fuerza Guerrera made his first appearance at a major EMLL show as he wrestled and defeated Negro Casas on EMLL's 48th Anniversary show. On November 6, 1983 Guerrera defeated Aguila Venezolana in a tournament final to win the vacant Mexican National Lightweight Championship, the first professional wrestling championships of his career. In May, 1984 Guerrera vacated the title when he moved from the lightweight weight class (between and ) and into the Welterweight weight class (between and ). On December 3, 1985 Fuerza Guerrera captured the Mexican National Welterweight Championship when he defeated Javier Cruz. Guerrera held the title for approximately 240 days before vacating the title as he left EMLL to work for other wrestling promotions in Mexico. By late 1988 Guerrera had returned to EMLL and captured the NWA World Welterweight Championship on October 4, 1988 when he defeated Solar II and won the highest ranking title in the Welterweight division at the time. Guerrera would go on to make several successful title defenses until he lost to Águila Solitaria on June 2, 1980. Guerrera regained the title three days later and went on to have an 808-day reign that included successful title defenses against Pantera II, Americo Rocca, his trainer Gallo Tapado, Misterioso and Octagón. In 1989 Guerrera also began working part-time in the Tijuana, Baja California based World Wrestling Association promotion, winning the WWA Welterweight Championship twice in 1989 and 1990.

[Q]: Question: Who was older, the Austrian at Ferrari or the number one driver at McLaren? Passage:He was replaced at Ferrari by Austrian Gerhard Berger for and he moved to McLaren as number two driver behind double and reigning World Champion Alain Prost. McLaren weren't as competitive in 1987 as they had been in 1984–1986, with Prost only adding three wins to his tally (and beating the record of 27 Grand Prix wins held by Jackie Stewart with his 28th win in Portugal) and failing to successfully defend his Drivers' Championship. Further podium finishes did follow for the Swede and Johansson finished sixth in the Drivers' Championship. Stefan Johansson's position at McLaren was considered by many as just a stop gap signing by team boss Ron Dennis who had failed to lure Ayrton Senna from Lotus due to him being under contract until the end of 1987 and always intended signing the Brazilian for . Johansson famously finished the 1987 German Grand Prix on three wheels having had a puncture on the last lap. He also finished second behind Prost in Belgium and added further podium finishes in Brazil, Spain and Japan. Despite 11 podiums in three seasons, Johansson was still winless and was not wanted by a top team (he had hoped to join Williams in 1988 as a replacement for the departing 1987 World Champion Nelson Piquet but Williams signed Riccardo Patrese instead). He did return to McLaren in a test-driver capacity in 1991, testing the Honda V12 engine at Suzuka in Japan.
