Input: Question: Of the Grand Prix that di Resta actually drove in, which had been in existence the longest? Passage:In December 2009, with Fisichella having moved to Ferrari and Liuzzi being promoted to the race team, di Resta took part in a test with the team at the Jerez circuit alongside J. R. Hildebrand. At the Autosport International show in January 2010, he was said to be close to a deal as the team's test and reserve driver for the 2010 season. The deal was announced on 2 February. Di Resta made his Formula One race meeting debut at the 2010 Australian Grand Prix, where he took part in the first free practice session in place of Sutil and placed 11th. He drove in the first practice sessions of all the following races until Monaco Grand Prix, where he did not take part. He resumed driving for the team at the European Grand Prix and the following British Grand Prix. After sitting out the German Grand Prix he returned for the Hungarian Grand Prix. Di Resta subsequently sat out the Belgian Grand Prix as Tonio Liuzzi and Adrian Sutil needed as much track-time as possible to get the feeling of the new parts. He participated in practice for the Italian Grand Prix, but did not participate in the Singapore or Japanese Grands Prix. The team elected that di Resta should miss the Korean Grand Prix to allow Liuzzi and Sutil to get used to the new track for the race.
