He participated in 33 Formula One World Championship Grands Prix for Fittipaldi and Arrows, debuting on 15 March 1981. He made 18 starts, not qualifying for the remaining fifteen races, although he ought to have started as the reserve in the 1982 Swiss Grand Prix. However, Ferrari withdrew Patrick Tambay's entry so late that Serra was not allowed to take part. Serra scored one championship point, for finishing sixth in the 1982 Belgian Grand Prix. After qualifying for the 1982 Canadian Grand Prix, Serra and countryman Raul Boesel had a short scuffle. Serra was furious at Boesel for blocking his last flying lap after waving Keke Rosberg by. Boesel denied that this was intentional. Serra made one CART Champ Car start in 1985 at the Portland International Raceway for Ensign Racing but suffered an engine failure.
 Link Information: Ensign entered Formula One in , with backing from pay driver, Rikky von Opel. Von Opel had driven for the team in Formula Three in 1972 and won the Lombard North Central, British Formula Three Championship that year. Based upon that success, von Opel commissioned a Formula One chassis. Their first season was not successful, von Opel only finished two races and the team's best result that season was 13th at the 1973 British Grand Prix. Question: How long had Ensign Racing been in business when Serra made one CART Champ Car start at the Portland International Raceway?

Output: Answer: 12


Input: Consider Input: Passage: Irish stars Jimmy Clausen and Golden Tate chose to forgo their final years of eligibility and declare for the 2010 NFL draft. The Irish also lost a number of seniors to graduation, including linemen Eric Olsen, Paul Duncan and four-year starter Sam Young. Other notable losses included running back James Aldridge, wideout Robby Parris, and George West on offense. On defense, ND lost senior captains Kyle McCarthy and Scott Smith, Raeshon McNeil, Sergio Brown, John Ryan and Ray Herring to graduation. Standout special teams player Mike Anello also finished his final year of eligibility. Sophomore defensive back E.J Banks left the team in August 2010, but will still be enrolled at the school. On August 31, within days of the September 4 season opener against Purdue, sophomore wide receiver Shaquelle Evans was granted his release from the team, and decided to enroll at UCLA. Freshman Derek Roback also left the program in early September, as his desire to play quarterback led to his transfer to Ohio
