Question: How many years after Wish You Were Here was released was The Wall released? Passage:Storm Thorgerson, who had done the majority of album covers for Pink Floyd, did the Echoes art which features recursive windows in an infinite regression as a nod to his own cover for 1969's Ummagumma, and the objects on each landscape refer to the Pink Floyd discography. For instance, there's the man on fire from Wish You Were Here, another wearing the Delicate Sound of Thunder lightbulb suit, dolls of the Atom Heart Mother cow and the Animals pig, a bike and both a brick wall and the hammers from The Wall. Eventually Thorgerson opted to make two images, with another used for the back cover. To create the idea on a photograph, various walls - which had varied measurements and angles to ensure that "nothing seemed to fit other than by eye through the lens." - were built and put in a country landscape in Sussex. Actors, props and fittings were set in and between those walls. The original design was one of two sketches submitted for Dream Theater's 1997 album Falling into Infinity, with the original being framed and hanging in the home of former Dream Theater drummer Mike Portnoy and is pointed out by Portnoy in his Hudson Music instructional drum DVD In Constant Motion.

Question: How many years did Justin's father's party have power before being defeated in the 1979 election? Passage:Trudeau lived at 24 Sussex Drive, Ottawa, the official residence of Canada's prime minister, from his birth until his father's government was defeated in the federal election on May 22, 1979. The Trudeaus were expected to move into the residence of the Leader of the Official Opposition, Stornoway, at 541 Acacia Avenue in Rockcliffe Park, but because of flooding in the basement, prime minister Joe Clark offered them Harrington Lake, the prime minister's official country retreat in Gatineau Park, with the expectation they would move into Stornoway at the start of July. However, the repairs were not complete so Pierre Trudeau took a prolonged vacation with his sons to the Nova Scotia summer home of his friend, MP Don Johnston, and later sent his sons to stay with their maternal grandparents in North Vancouver for the rest of the summer while he slept at his friend's Ottawa apartment. Justin and his brothers returned to Ottawa for the start of the school year, but lived only on the top floor of Stornoway while repairs continued on the bottom floor. His mother purchased and moved into a new home nearby at 95 Queen Victoria Avenue in Ottawa's New Edinburgh in September 1979. The Trudeaus returned to the prime minister's official residence in February 1980 after the election that returned his father to the Prime Minister's Office.

Question: What modern day country is Chipata part of? Passage:Hunzahúa, heir of Idacansás, was a cacique in the sacred valley of the iraca and was chosen by the other caciques of the region to make peace between the battling parties. He became the first zaque of the northern Muisca region based in Hunza, present-day Tunja, and one of his policies was the ban on the use of weapons. According to Muisca scholar Javier Ocampo López, who wrote extensively about the religion and mythology of the Muisca, his mother was named Faravita and his sister Noncetá. Legend tells that Hunzahúa fell in love with his sister and made her his wife when he left Hunza for Chipatá. Faravita, the mother of the zaque, disagreed with the marriage of her two children and attacked the couple, spilling a bowl of chicha. This created the Hunzahúa Well. When Hunzahúa saw what his mother had done, and the Muisca protesting against his incest, he damned Hunza and the surrounding valley. Noncetá gave birth to a son in Susa, but the young boy turned into a rock. The sad couple traveled further, to the Tequendama Falls. Here, they changed into two rocks at either side of the sacred waterfall.
