Input: Consider Input: Question: Who was the first president of the college where Heinrich studied? Passage:Georg Heinrich August Ewald (16 November 1803 – 4 May 1875) was a German orientalist, Protestant theologian, and Biblical exegete. He studied at the University of Göttingen. In 1827 he became extraordinary professor there, in 1831 ordinary professor of theology, and in 1835 professor of oriental languages. In 1837, as a member of the Göttingen Seven, he lost his position at Göttingen on account of his protest against King Ernst August's abrogation of the liberal constitution, and became professor of theology at the University of Tübingen. In 1848, he returned to his old position at Göttingen. When Hanover was annexed by Prussia in 1866, Ewald became a defender of the rights of the ex-king. Among his chief works are: Complete Course on the Hebrew Language (), The Poetical Books of the Old Testament (), History of the People of Israel (), and Antiquities of the People of Israel ().

Input: Consider Input: Question: What war were the boats like Kennedy was on used in? Passage:Within weeks, many Americans could recite favorite lines from the record, including "the rubber schwan [swan] is mine", and "move ahead...with great vigah [vigor]", the latter lampooning the President's own words. The album poked fun at Kennedy's PT-109 history; the rocking chairs he used for his painful back; the Kennedy clan's well-known athleticism, football games and family togetherness; children in the White House; and Jackie Kennedy's soft-spoken nature and her redecoration of the White House; and many other bits of knowledge that the public was eager to consume. Kennedy himself was said to have given copies of the albums as Christmas gifts, and once greeted a Democratic National Committee group by saying, "Vaughn Meader was busy tonight, so I came myself." According to UPI reporter Merriman Smith, during a Cabinet meeting Kennedy played the entire record for everyone. At one press conference, Kennedy was asked if the album had produced "annoyment (sic) or enjoyment." He jokingly responded, "I listened to Mr. Meader's record and, frankly, I thought it sounded more like Teddy than it did me. So, now he's annoyed."
