Input: Consider Input: Question: Who came second behind Diminuendo at The Oaks? Passage:In 1988 Melodist was ridden in all four of her races by Walter Swinburn. She did not run as a three-year-old until 22 May when she was sent to Italy for the Oaks d'Italia over 2400 metres on soft ground at the San Siro racecourse in Milan. The finish of the race was dominated by overseas challengers as Melodist won by one and a half lengths from her fellow British raider Asl (previously second in the Musidora Stakes) with the French-trained Summer Trip a neck away in third. On 9 July Melodist was one of nine runners to contest the Irish Oaks over one and a half miles at the Curragh and started at odds of 11/1. The 2/9 favourite for the race was Diminuendo, ridden by Steve Cauthen, who had won The Oaks by four lengths. Both Melodist and Diminuendo were owned by Sheikh Mohammed and based at Newmarket, but whereas Melodist was trained by Stoute, the favourite was trained by Henry Cecil at Warren Place. The other fancied runners were Dancing Goddess (second in the Irish 1000 Guineas), Miss Boniface (Ribblesdale Stakes) and Silver Lane (Prix de la Grotte). Melodist tracked the leaders before overtaking Miss Boniface before going to the front a furlong and a half from the finish. She faced a strong late challenge from Diminuendo and after a sustained struggle the two fillies crossed the line together with the judge declaring a dead heat.

Input: Consider Input: Question: How old was the Duke of Saxony when he appointed Adolf I to hold Holstein and Stormarn? Passage:He was appointed to hold as fiefs Holstein and Stormarn, including Hamburg, by Lothair, Duke of Saxony, in 1111. By this appointment Adolf became the leader of the defence of Germany against the Wagri. Allied with Henry, the prince of the Obotrites, he repeatedly waged war on Wagria and the Rugians. After Henry's death (1127), Adolf remained allied with his sons Canute and Sventepolk, but they were soon dead and Lothair, by then King of Germany, had made Canute Lavard, a Danish prince, Duke of Schleswig. Feeling his authority threatened by the Danish upstart, Adolf attacked his castle of Albergs, captured the garrison, and destroyed its defences. He left his counties intact to his second son, Adolf II, since his eldest, Hartung, had been killed in the Second Battle of Chlumec in 1126.

Input: Consider Input: Question: Did Vordtriede teach French and German Literature in the United States? Passage:After the Nazis came to power, he emigrated to Switzerland in 1933 and to the United States later. He began his studies in Zurich and worked part-time as a house teacher. Meanwhile, he wrote articles and book reviews for the Neue Zürcher Zeitung, using several pseudonyms because of prohibition of work. He earned his PhD and taught French and German Literature at various universities, including Princeton University and University of Wisconsin-Madison. During a journey to Europe, Vordtriede was surprised by the outbreak of the Second World War and interned as an Enemy alien in occupied France. By interventions, he became free months later and was allowed to go back to America. He met his mother in New York City late in 1941, who also emigrated to the USA. He received the American citizenship in 1946 and became a Guggenheim Fellow in 1957. His sister Fränze emigrated in 1947 and went to Philadelphia.
