Question: How many days did the battle the Baron was killed in last? Passage:While they were travelling to Europe in 1914, the First World War broke out and the ship carrying Von Wolf and his wife was diverted to Rio de Janeiro. Jayta Humphreys had retained her American citizenship and found passage to Europe on a Dutch ship; legend has it the Baron had to travel disguised as a woman. On arrival in Europe the Baron rejoined the German army, and was killed at the Battle of the Somme in 1916, just two weeks after signing up. His wife could not bring herself to return to Namibia alone and never again laid claim to the majestic castle. She stayed on the coast of the Tegernmeer in Bavaria (since her stepfather had been appointed consul general in Munich), before settling in the late 1930s in Zurich, where she met and married Erich Schlemmer, the consul general of Siam. After the Von Wolfs left South Africa, their friend Max Count von Lüttichau was given executorship of the farm, but it declared bankruptcy shortly after World War I, and since the South African government paid no compensation for this or several wartime raids, the house was sold for £7,500 to the Swedish Murrmann family. The new owner died shortly after his arrival and his son was killed in World War II, following which the castle was sold for 25,000 pounds to the private company Duwisib Pty Ltd and the rest of the land was divided and sold off. Jayta returned to the US to stay with her parents in Summit, New Jersey. Several changes in ownership later, the castle was acquired by the government in 1979 and extensively refurbished in 1991.

Question: What were the other three songs on the Woodchuck EP beside the promotional single? Passage:Formed in 2006, Go:Audio signed to Epic Records in May 2007. Their promotional single, Woodchuck, was released to many radio and music television stations in late January the following year to promote the 4-track Woodchuck EP. It received heavy rotation, most notably from Kerrang! 105.2 which helped make the accompanying music video one of the most played on YouTube in the United Kingdom that month. The band's first official single, "Made Up Stories" was released on 26 May 2008 and the video, in which a hand-picked group of fans participated, was frequently shown on Kerrang!, Scuzz and Fizz TV (now known as Starz TV). Following the single's release the band announce via their MySpace page that their debut album would carry the same title. Recording for the album took place in Sussex, England and was completed by early June 2008 for a 25 August release. The album was leaked in late June 2008, and a decision was made to delay the release date until 19 January 2009. The second single from Made Up Stories was "She Left Me", released on August 11, the first day of their UK headline tour. The band debuted an acoustic version of the track on 6 August on Rocklouder.co.uk. "She Left Me" just missed on reaching the UK Top 40, peaking at No. 41.

Question: How long had Dave Roberts been manager for the year Culberson was signed to the Dodgers? Passage:Culberson was signed by the Dodgers in November 2015 and invited to spring training, where he impressed new Dodgers manager Dave Roberts. After an injury to Howie Kendrick opened a spot for him, Culberson made the Dodgers 2016 Opening Day roster. He was designated for assignment in July and optioned to the Oklahoma City Dodgers, then recalled a month later. Culberson ended the big club's final home game of the season with a walk-off home run against former Rockies teammate Boone Logan, clinching the Dodgers' fourth consecutive National League West division title. He played in 34 games for Los Angeles, hitting .284 and in 70 games for Oklahoma City, hitting .260. He had no hits in seven at-bats with two strikeouts in the 2016 National League Division Series. He was outrighted to the minors and removed from the 40-man roster on December 9, 2016. He was assigned to Oklahoma City to begin the season. He remained in the minors for the conclusion of the AAA season, hitting .250 in 108 games and returned to the majors with the Dodgers on September 4. In 15 games for the Dodgers, he hit .154 with two hits in 13 at-bats. When starting shortstop Corey Seager was left off of the 2017 NLCS roster because of a back injury, Culberson was added to the post-season roster. He appeared in all five games of the series, with five hits in 11 at-bats for a .455 average. In the 2017 World Series, Culberson had three hits in five at-bats, including his first career post-season home run, which he hit off Chris Devenski of the Houston Astros in the 11th inning of Game Two.
