Teacher: Now, understand the problem? Solve this instance: Question: How many years did it take to develop the Sierra turbo? Passage 1:The squadron was originally formed as VMJ-1, and had origins in the earlier VJ-6M. On July 7, 1941 they were redesignated VMJ-152 at Marine Corps Air Station Quantico. They moved to San Diego a few months later and shipped out to the South Pacific on October 10, 1942. They joined Marine Aircraft Group 25 on October 25, 1942, and immediately began flying missions in support of Marines engaged in the Battle of Guadalcanal. In November 1942, the squadron became part of the joint-service South Pacific Combat Air Transport Command. Following this they made numerous supply drops during the New Georgia Campaign in 1943. The squadron was redesignated again to VMR-152 on June 3, 1944. In 1944, the squadron was flying in support of the Battle of Bougainville and would be based on Bougainville for the remainder of the war. From here the squadron also supported allied forces during the Philippines Campaign (1944–45) and the Battle of Okinawa. Following the surrender of Japan, the squadron flew in support of the 1st Marine Division during their occupation of Northern China from 1945 - 1947. Following their China duty the squadron returned to the United States where they were based at Marine Corps Air Station El Toro, California.
 Passage 2:Sia performed "Chandelier" on The Ellen DeGeneres Show on 19 May 2014, with Ziegler recreating the choreography in the music video. Sia also performed the song on Late Night with Seth Meyers on 9 June 2014, with Girls star Lena Dunham performing new choreography. In July 2014, Sia performed the song on Jimmy Kimmel Live!, and Ziegler taught host Jimmy Kimmel and his sidekick Guillermo some of the dance moves from the music video. In July 2014, Sia performed the song on the VH1's show "SoundClash", along with her songs "Elastic Heart" and "Big Girls Cry" from the album. Sia sang the song on Dancing with the Stars, with Ziegler dancing a duet with Allison Holker, and at the 2014 We Can Survive Concert at the Hollywood Bowl. In February 2015, Sia sang the song in a cluttered apartment set for the 2015 Grammy Awards telecast. Ziegler danced in a cluttered apartment with actress Kristen Wiig. For all of these performances, Sia sang the track with her back to the camera. She performed the song on Saturday Night Live in January 2015, veiled, with a sad-looking mime who performed the lyrics in American sign language.
 Passage 3:The second year of Group A in Australia saw the domination of the JPS Team BMW team fade with several other teams pushing forwards. Most spectacularly was the return of Nissan Motorsport Australia (now under the leadership of former Bathurst winner Fred Gibson) with the newly homologated Nissan Skyline DR30 RS turbo. Led by long time Nissan lead driver George Fury they were the main rival for another new team, the John Sheppard run Volvo Dealer Team, a factory supported team which succeeded the Mark Petch Motorsport Volvo team of 1985. The Touring Car Championship became a two horse race between Volvo's Robbie Francevic and Fury. Fury was never able to haul in Francevic's early points lead and Francevic was crowned champion. Francevic was fired from the Volvo Dealer Team by Sheppard the day after the Castrol 500 at Sandown after refusing to drive what he believed would be an un-competitive car which had only been completed at the meeting started. He then returned to the Mark Petch team as they began development of a Ford Sierra turbo. Although Francevic won the ATCC in the car, 1986 was the last time the Volvo 240T was seen in Australian touring car racing.
