Question: How does warm water strengthen a hurricane? Passage 1:Originally a backing band for burlesque shows, in their early years DeVotchKa also toured with burlesque performer and model Dita Von Teese. Numerous nationwide tours in support of self-released records earned the band an underground following. Their song "How It Ends" introduced the band to a wider audience after being featured in the trailer for Everything Is Illuminated, in a Gears of War 2 trailer called "The Last Day", and in an episode of Everwood (Season 4). Their performance at the 2006 Bonnaroo music festival was considered a breakout event. In between tours, the band was picked by first time film directors Jonathan Dayton and Valerie Faris to score Little Miss Sunshine, a 2006 film that would go on to garner four Academy Award nominations. DeVotchKa, along with composer Mychael Danna, composed and performed the majority of the music for the film's soundtrack and were nominated for a 2006 Grammy Award for Best Compilation Soundtrack. The main song, "The Winner Is", was also used in a commercial by the French-based environment and energy company Suez and the Dutch pension fund PGGM.
 Passage 2:Hurricane Dorian was the strongest hurricane to affect the Bahamas on record, causing catastrophic damage in the Abaco Islands and Grand Bahama in early September 2019. The fifth tropical cyclone, fourth named storm, second hurricane, and first major hurricane of the annual hurricane season, Dorian originated from a westward traveling tropical wave that was located over a thousand miles east of the Windward Islands on August 23. The disturbance rapidly organized and became a tropical depression and later a tropical storm, both on August 24. The newly formed Dorian struggled to intensify over the next few days due to a combination of dry air and vertical wind shear. The storm passed over Barbados and entered the Caribbean Sea on August 26 as it gradually strengthened. Dorian made landfall in St. Lucia on the next day, which caused serious disruption to the system's structure. Initially predicted to strike Hispaniola, Dorian's track gradually shifted to the east as the storm neared Greater Antilles. Due to land interaction and the dry air, Dorian's center reformed north of its previous location, causing the system's track to shift northward. The storm then turned towards the northwest as it traveled through a weakness in a ridge. A combination of the dry air and shear relaxing as well as the warm sea surface temperatures, allowed Dorian to become a Category 1 hurricane as it passed over St. Thomas on August 28. The storm developed an eye in satellite imagery soon after, but dry air still continued to disrupt the system. The commencement of an eyewall replacement cycle on August 29 temporarily impeded intensification, but Dorian completed the cycle the next morning and soon resumed strengthening.
 Passage 3:Sébastien Ogier held the lead of the rally from start to finish; with three stage wins on the first day, Ogier held a lead of 46.6 seconds over Mikko Hirvonen, who battled for second with Thierry Neuville, with a difference of only 3.1 seconds at the end of the day. Both Qatar M-Sport World Rally Team drivers, Mads Østberg and Evgeny Novikov retired. On the second day, Hirvonen started with a stage win, but on the next stage went wide and got stuck into a ditch, leaving second place to Neuville. Ogier's teammate, Jari-Matti Latvala recovered from 12th position after a puncture on stage one, to finish third. Dani Sordo was the best Citroën finisher in fourth, ahead of Martin Prokop in fifth, while Elfyn Evans finished sixth on his début in a World Rally Car. Michał Kościuszko got his best result of the year in seventh, ahead of Østberg – recovering from his accident – to finish eighth via Rally-2. Robert Kubica got his first championship points by finishing ninth and Khalid Al Qassimi completed the top ten finishers.
