PROBLEM: 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.

PROBLEM: Question: Who was the mayor of Stockholm the year Samuel-Cahn moved to Mandatory Palestine? Passage:Samuel-Cahn was born in Oslo, Norway. During the Nazi occupation of Norway, in 1942, her father, a rabbi, was warned that he would be arrested by the Germans. He refused to leave in order to try to support his community. In September, her father was ordered to report to the Gestapo office, where he was questioned and later sent to Auschwitz. Later that year, the Nazis were going to arrest the other Jews in Oslo, however Samuel-Cahn's family were moved by members of the underground, Ingebjrg Sletten-Fosstvedt and Sigrid Helliesen Lund, to safety and later to a refugee camp in neutral Sweden. In order to cross the border, Samuel-Cahn and the rest of her family had to hide in trucks used to transport potatoes. In Stockholm, Samuel-Cahn's family found out that her father had been killed in Auschwitz. In 1946, Samuel-Cahn, her mother and brothers moved to Mandatory Palestine (part of which later became Israel).

PROBLEM: Question: How many days passed between Hamilton's first win of the season and his last? Passage:Mercedes won their first World Constructors' Championship after taking a 12 finish in Russia. Lewis Hamilton won his second World Drivers' Championship after a season-long battle with teammate Nico Rosberg. Rosberg won the Australian and Monaco Grands Prix, and Hamilton the races in Malaysia, Bahrain, China and Spain after retiring in Australia. The Mercedes team's run of victories ended in Canada where Rosberg and Hamilton were simultaneously hit with a power unit failure that put additional strain on their brakes. Hamilton was forced out of the race and while Rosberg was able to continue, his performance deteriorated and he ultimately finished second. Mercedes returned to the top of the podium in Austria, with Rosberg leading Hamilton across the finish line for his third victory of the season. Hamilton reclaimed ground in the championship standings in Britain winning after Rosberg was forced out with gearbox issues. Rosberg claimed the win in Germany, while Hamilton recovered to third after an accident in qualifying saw him start from twentieth place. Hamilton finished third in Hungary after starting from pit lane, ahead of Rosberg. Rosberg had to settle for second place in Belgium after contact with Hamilton early in the race, which ultimately prompted Mercedes to retire Hamilton's car. Hamilton went on to claim his sixth win of the season in Italy, ahead of Rosberg. Hamilton reclaimed the championship lead with a win in Singapore, while Rosberg was retired with a broken wiring loom. Hamilton claimed the win in rain- and accident-shortened Japan, ahead of Rosberg. Hamilton won the inaugural race in Russia, once again ahead of Rosberg. The result was enough for Mercedes to secure their first World Constructors' Championship. Hamilton took his fifth consecutive win for the first time in his career in the United States, again ahead of Rosberg. Rosberg took his fifth win of the season in Brazil, with Hamilton finishing in second. Hamilton carried a seventeen-point advantage into the title-deciding and went on to win the race while Rosberg struggled with electrical problems and finished outside the points. With eleven pole positions to his name, Rosberg won the inaugural FIA Pole Trophy.
