Question: Where was the choreographer of the fifth season's performance of "Ruby Blue" born? Passage 1:Dál Riata is said to have been founded by the legendary king Fergus Mór (Fergus the Great) in the 5th century. The kingdom reached its height under Áedán mac Gabráin (). During his reign Dál Riata's power and influence grew; it carried out naval expeditions to Orkney and the Isle of Man, and assaults on the Brittonic kingdom of Strathclyde and Anglian kingdom of Bernicia. However, King Æthelfrith of Bernicia checked its growth at the Battle of Degsastan in 603. Serious defeats in Ireland and Scotland during the reign of Domnall Brecc (died 642) ended Dál Riata's "golden age", and the kingdom became a client of Northumbria for a time. In the 730s the Pictish king Óengus I led campaigns against Dál Riata and brought it under Pictish overlordship by 741. There is disagreement over the fate of the kingdom from the late 8th century onwards. Some scholars have seen no revival of Dál Riatan power after the long period of foreign domination ( to ), while others have seen a revival under Áed Find (736–778). Some even claim that the Dál Riata usurped the kingship of Fortriu. From 795 onward there were sporadic Viking raids in Dál Riata. In the following century, there may have been a merger of the Dál Riatan and Pictish crowns. Some sources say Cináed mac Ailpín (Kenneth MacAlpin) was king of Dál Riata before becoming king of the Picts in 843, following a disastrous defeat of the Picts by Vikings. The kingdom's independence ended sometime after, as it merged with Pictland to form the Kingdom of Alba.
 Passage 2:In 1944 Fölkersam's unit transferred to the Waffen-SS and became the major part of SS-Jagdverband Ost. This unit was active on the Eastern Front and took part in the kidnapping of Miklós Horthy, Jr. and the deposition of his father, the Hungarian regent Miklós Horthy in Operation Panzerfaust. During the Battle of the Bulge, Fölkersam participated in Operation Greif, and worked in close coordination with Otto Skorzeny. In January 1945, having posted to the Eastern Front, he fought against the advancing Red Army in central Poland. Adrian von Fölkersam was killed in action on 21 January 1945 near Inowrocław, Poland. At the time of his death, he was an SS-Hauptsturmführer (captain), and was in command of the SS-Jagdverband Ost.
 Passage 3:Three songs have been used for the reality television series So You Think You Can Dance. "Ramalama (Bang Bang)" was used for a group performance on the sixth week of the second season. Contestants wore costumes and make-up to show them as zombies in a performance combining the 1968 horror film Night of the Living Dead with Michael Jackson's 1983 music video for "Thriller". At the 59th Primetime Emmy Awards, the performance was part of a three-way tie for Outstanding Choreography with a So You Think You Can Dance performance of Céline Dion's "Calling You", choreographed by Mia Michaels, and the television special Tony Bennett: An American Classic. "Night of the Dancing Flame" was used for a couple's jazz dance in the fourth week of the following season with contestants Neil Haskell and Lauren Gottlieb. The performances were choreographed by Wade Robson. Robson also did a number to "Ruby Blue" in the fifth season of So You Think You Can Dance.
