Question: How many total tracks were there on Born to Die? Passage:After uploading a few of her tracks to her YouTube channel, Del Rey was discovered and got signed by Stranger Records to release her debut single "Video Games". She told The Observer that "Video Games" was never intended to be a single, but she enjoyed the video and uploaded on the internet. The song earned her a Q Award for "Next Big Thing" in October 2011. Later that month, she signed a joint record deal with Interscope Records and Polydor to release her second studio album, Born to Die. Del Rey built anticipation to the album by doing a number of live appearances, such as promotional concerts at the Bowery Ballroom and at the Chateau Marmont, and with performances at television shows such as De Wereld Draait Door, and Later... with Jools Holland. To further promote the upcoming release of Born to Die, Interscope Records released the EP in the United States and Canada on January 10, 2012. The four tracks that appear on the EP ("Video Games", "Born to Die", "Blue Jeans", and "Off to the Races") were previously available for purchase as singles in international markets.

Question: How many leaders run the priestly class? Passage:Traditional African religions like the Serer religion (A at Roog) are adhered to by devout worshippers of Roog the supreme deity in Serer religion. The Serer ethnic group who adhere to the tenets of Serer religion (including those Senegalese who syncretize) honour the Serer pangool and have ancient rituals and festivals devoted to them. The religious affairs of Serer religion devotees are usually headed by the Saltigue (the Serer priestly class) which in ancient times was the preoccupation of the Serer lamanic class. Some of these religious festivals or ceremonies include the Ndut (rite of passage), Xooy (divination festival once a year in Fatick), and the Raan festival. Senegalese hold several ancient beliefs, such as small efforts of 'thanks' or demands, such as protection from water. They also place great importance on the Baobab tree, which is known as the "House of the Spirits." The baobab tree along with other sacred trees figure prominently in the Serer creation narrative. Among the Jola people, some religious festivals include the Samay, Kumpo and the Niasse.

Question: Of the people Hammer defeated in his ten match winning streak, which is the youngest? Passage:After briefly continuing his tag team with Big Josh, Hammer returned to singles competition and faced Steve Austin for the World Television Championship on the January 12 episode of Main Event, but was unable to win the title. After the loss, Hammer competed sporadically throughout the rest of the spring (including a brief feud with JT Southern) before returning full-time in August 1992. Hammer would fall to Greg Valentine and Nikita Koloff before his push began to accelerate. In September he went on a ten match winning streak, defeating Dallas Page, Vinnie Vegas (Kevin Nash), and Super Invader (Hercules Hernandez). He received a US title shot against Rick Rude on the November 21st episode of WCW Power Hour but came up short. Hammer teamed with Erik Watts at Halloween Havoc and was victorious against The Vegas Connection. For the remainder of October and November he was strongly pushed, going 19-2 in a streak that included victories over Tony Atlas, The Barbarian, and Mustafa Saed. He would also team with Brad Armstrong in a brief feud with Page and Vegas.
