Question: How many leaders run the priestly class? Passage:Traditional African religions like the Serer religion (A ƭat 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: What is the population of the city where Haschka was born and died? Passage:Haschka was born and died in Vienna. In his youth, he was a member of the Society of Jesus. On the suppression of the Society (1773) he devoted himself, in secular life, to poetry, this was now to become his vocation and his means of livehood. His pupil, the wealthy Johann Baptist von Alxinger, an imitator of Christoph Martin Wieland, came to his assistance. Haschka also found aid in the home of poet Karoline Pichler. Having left the Jesuits, under the influence of Josephinism, he became a freemason and wrote odes against the papacy during the presence of Pius VI in Vienna, as well as against the religious orders. He returned to Catholicism after the death of Joseph II, Holy Roman Emperor, and was selected to compose a national anthem, which was first sung on 12 February 1797, at the celebration of Francis II's birthday. Haschka was given a position as assistant in the library of the University of Vienna and was made instructor in aesthetics in the newly founded Theresianum. He retired in 1824.

Question: Which of the two devices that Project Dream was considered for release on sold more units? Passage:Project Dream was the codename of a role-playing video game (RPG) that served as the basis for the 1998 game Banjo-Kazooie. Developed by Rare, it was aimed for release on the Super Nintendo Entertainment System (SNES), and later the Nintendo 64 (N64). The plot revolved around a young boy, Edson, who caused trouble with pirates. The SNES version of Dream used an isometric perspective and had a fairy tale-like theme. After transitioning to the N64, the project became a more complex 3D RPG that had a greater emphasis on the pirate theme. Eventually, Dream was scaled back to a linear platform game in the vein of Donkey Kong Country (1994) that starred Banjo the bear, who became the protagonist of Banjo-Kazooie.
