Question: What was the inaugural year of the air race series that Rust also hosted and commentated? Passage 1:Whale was born into a large family in Dudley, Worcestershire. He discovered his artistic talent early on and studied art. With the outbreak of World War I he enlisted in the British Army and became an officer. He was captured by the Germans and during his time as a prisoner of war he realized he was interested in drama. Following his release at the end of the war he became an actor, set designer and director. His success directing the 1928 play Journey's End led to his move to the US, first to direct the play on Broadway and then to Hollywood, California, to direct films. He lived in Hollywood for the rest of his life, most of that time with his longtime companion, producer David Lewis. Apart from Journey's End (1930), which was released by Tiffany Films, and Hell's Angels (1930), released by United Artists, he directed a dozen films for Universal Pictures between 1931 and 1937, developing a style characterized by the influence of German Expressionism and a highly mobile camera.
 Passage 2:Caisse de dépôt et placement du Québec (CDPQ; lit. Quebec Deposit and Investment Fund, also referred to in English-language media as the Caisse) is an institutional investor that manages several public and parapublic pension plans and insurance programs in Quebec. It was founded in 1965 by an act of the National Assembly under the government of Jean Lesage. It is the second-largest pension fund in Canada, after the Canada Pension Plan (CPP). As at December 31, 2018, CDPQ managed assets of C$309.5 billion invested in Canada and elsewhere. CDPQ is headquartered in Quebec City in the Price building and has its main business office in Montreal at Édifice Jacques-Parizeau.
 Passage 3:In 1997 he was hired by Ten to host the Australian Super Touring Championship for 2-litre Touring Cars - a position previously held by his close friend Leigh Diffey, who had moved on to Network Ten's V8 Supercar coverage. Rust commentated the Australian Super Touring Championship for 2 years before starting work as V8 pit reporter late in 1998. He was a part of Ten's V8 coverage for almost 10 years - even hosting and anchoring the commentary on occasions. During this period the station won numerous Logie Awards for its broadcast of the famous Bathurst 1000 and Rust developed a reputation as a pit specialist also working on the Gold Coast Indy 300 and the Australian Grand Prix in Melbourne. Despite an offer to join the Seven Network in 2007, Rust stayed with Ten to front the station's MotoGP and F1 broadcasts and its long running magazine motorsport show RPM. He also hosted and commentated Ten's coverage of the Red Bull Air Race series.
