Input: Consider Input: Question: How many pages long was Strout's first novel? Passage:Strout's first novel, Amy and Isabelle (1998) met with widespread critical acclaim, became a national bestseller, and was adapted into a movie starring Elisabeth Shue. Her second novel, Abide with Me (2006), received critical acclaim but ultimately failed to be recognized to the extent of her debut novel. Two years later, Strout wrote and published Olive Kitteridge (2008), to critical and commercial success grossing nearly $25 million with over one million copies sold as of May 2017. The novel won the 2009 Pulitzer Prize for Fiction. The book was adapted into a multi Emmy Award-winning mini series and became a New York Times bestseller. Five years later, she published The Burgess Boys (2013), which became a national bestseller. My Name Is Lucy Barton (2016) was met with international acclaim and topped the New York Times bestseller list. Lucy Barton later became the main character in Strout's 2017 novel, Anything is Possible. A sequel to Olive Kitteridge, titled Olive, Again, was published in 2019.

Input: Consider Input: Question: Was the Social Democratic Party around when Knochel was conscripted into the Imperial Army? Passage:Wilhelm Knöchel was born into a Social Democratic working class family in Offenbach, a short distance upriver from Frankfurt. He qualified and worked as a factory machine operator ("Dreher"). In 1917 he was conscripted into the Imperial Army, shortly after which he was badly wounded. There are also references to his having worked as a mines maintenance engineer ("Grubenschlosser"). In 1919, with Germany affected by acute economic hardship and, especially in the cities, a succession of revolutionary uprisings, Knöchel joined the Social Democratic Party ("Sozialdemokratische Partei Deutschlands" / SPD). By 1920 he had relocated in search of work to the industrially vital and internationally critical Ruhr region. Sources differ over whether it was in 1920 or 1923 that he switched to the recently created Communist Party. Between 1924 and 1930 he was a member of the party leadership team for the Dortmund region ("...des Unterbezirk Dortmund"). In 1930, following the death of his first wife, he returned to Offenbach, where it was arranged that his daughter should be brought up by relatives. Knöchel was now employed as a party official.

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, Ingebjørg 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).
