Input: Question: Which of Microsoft's gaming systems for which the Forza series was developed has sold the most units? Passage 1:The show features an ensemble cast. For the first season, nine actors received the star billing: Connie Britton as Rayna Jaymes, a 40-year-old country music superstar singer whose stardom is beginning to fade; Hayden Panettiere as Juliette Barnes, a bubblegum country pop singer and former teen star sensation who is determined to replace Rayna as the top superstar of country music; Clare Bowen as Scarlett O'Connor, a poet and songwriter Deacon's niece, and musician partner with Gunnar who works at the Bluebird Cafe which is where she is first noticed and performs; Eric Close as Theodore "Teddy" Conrad, Rayna's husband who, after a business failure, is now living on his wife's income. He runs for mayor with help from his father-in-law and wins election, later divorcing Rayna; Charles Esten as Deacon Claybourne, songwriter, lead guitar player, Rayna's former lover and biological father of her oldest child.; Jonathan Jackson as Avery Barkley, an aspiring musician with a bad-boy streak. He and Scarlett are in a relationship when the series begins, but soon separate; Sam Palladio as Gunnar Scott, a kind-hearted aspiring musician who dates Scarlett in season one, and dates Zoey in season two; Robert Wisdom as Coleman Carlisle, a one-time mayoral candidate, and later Deputy Mayor, close friend of Rayna, and serves as Deacon's sobriety sponsor; and Powers Boothe as Lamar Wyatt, Rayna's father and a wealthy, powerful and controlling patriarch and local politician who disapproves of his daughter's career as a country singer.
 Passage 2:Klammer first showed signs of promise in the second half of the 1973 World Cup season, finishing second in the St. Anton downhill behind Bernhard Russi of Switzerland, the reigning Olympic and World Cup downhill champion. Klammer, age 19, followed this up with a third at St. Moritz and a third in the giant slalom at Mont Sainte-Anne (the only time he finished on the podium in a World Cup Giant Slalom in his career). The following season he finished second in the downhill standings behind Roland Collombin of Switzerland, his nemesis that season. After beating Collombin and Russi at Schladming in December 1973 under terrible conditions, Collombin bested him at Garmisch, Avoriaz, and Wengen. In December 1974, Collombin fell at Val-d'Isère, as he had the previous year. This time Collombin broke his back in a training run, unfortunately ending his promising career. Klammer won that race and every other downhill that 1975 season, except Megève, where one of his skis came off; without this incident, he would have won the overall World Cup title in March 1975, due to a good slalom result two days before at Chamonix, which would have granted him at least a third place (15 points) for the AK-combined of slalom Chamonix / downhill Megève. In the Olympic test event at Patscherkofel at Innsbruck in January 1975, Klammer had defeated defending Olympic champion Bernhard Russi of Switzerland, the runner-up, by nearly a half-second.
