Q: 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, 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).

Q: Question: Which race that Frankel won in his four-year-old season had a higher purse? Passage:Cecil's success in 2011 was partly due to his training of the Khalid Abdullah-owned Frankel. In the 2010 season Frankel won the Royal Lodge Stakes and Group One Dewhurst Stakes. The following year he continued unbeaten, winning the Greenham Stakes, the 2,000 Guineas, the St. James's Palace Stakes at Royal Ascot, the Sussex Stakes and the Queen Elizabeth II Stakes. His six length victory in the 2,000 Guineas was described as "one of the greatest displays on a British racecourse". After his win in the Sussex Stakes Cecil himself described Frankel as "the best horse I've ever seen". Timeform and the International Federation of Horseracing Authorities rated him the best horse in the world. In his four-year-old season Frankel won the Group One Lockinge Stakes at Newbury before an eleven length victory in the Queen Anne Stakes at Royal Ascot, described in one national newspaper as "possibly the best single performance by any horse, on any track, since three Arabian stallions were imported into Britain to found the thoroughbred breed in the early years of the 18th century". Timeform raised their rating to 147, making Frankel the highest rated horse in their history. He won a second Sussex Stakes, at odds of 1–20, and then stepped up in distance to win by seven lengths the Juddmonte International Stakes at York over 10 furlongs. In October 2012 Frankel won the Champion Stakes at Ascot to finish his career unbeaten. "He's the best I've ever had, the best I've ever seen", Cecil told the BBC after the race, "I'd be very surprised if there's ever been a better."

Q: Question: Which neighbouring village to Homberg had the most residents? Passage:The mediaeval historical development that Homberg experienced closely matches that experienced by neighbouring villages such as Kirrweiler, Deimberg, Buborn, Langweiler and Hausweiler. Like these places, Homberg belonged until 1140 to the Nahegau, and then thereafter until 1263 to the Waldgraviate, which itself had arisen from the Nahegau. As far as is now known, Homberg had its first documentary mention in 1319. In the document in question, an arbitrator confirmed that Waldgrave Friedrich of Kyrburg had to forgo all his claims to rights to Hoenberg and a series of other places in the “Gericht auf der Höhe” (“Court on the Heights”). The Gericht auf der Höhe was said to be a constituent district of the “Hochgericht auf der Heide” (“High Court on the Heath”), which comprised, roughly, lands in a triangle bounded by the Nahe, the Glan and the Steinalp (another river). The 1319 document dealt with a dispute between the two Waldgravial sidelines of Kyrburg and Dhaun-Grumbach. About 1344, in his own documents, the name “Friedrich von Hoenberg” appeared. He was obviously a nobleman who came from Homberg, but nothing else about him has come to light. The villages under the Gericht auf der Höhe, among which was Homberg, were pledged first, in 1363, by Johann von Dhaun to Sponheim-Starkenburg and then in 1443 by Waldgrave and Rhinegrave Friedrich to the last of the Counts of Veldenz, namely Friedrich III, whose daughter Anna married King Ruprecht's son Count Palatine Stephan. The document whereby this arrangement was laid out referred to the village's inhabitants as the “poor people of Grumbach”. By uniting his own Palatine holdings with the now otherwise heirless County of Veldenz – his wife had inherited the county upon her father Friedrich III's death in 1444, but not his comital title – and by redeeming the hitherto pledged County of Zweibrücken, Stephan founded a new County Palatine, as whose comital residence he chose the town of Zweibrücken: the County Palatine – later Duchy – of Palatinate-Zweibrücken. Thus, Homberg, and the other villages, too, lay within this duchy, but they were all returned to the Waldgraviate in 1477 when the pledge was redeemed.
