Input: Consider Input: Question: Where was Schunk's conductor for his 1986 tenor solo performance born? Passage:From 1979 onwards, he worked as a freelance singer, performing internationally. He appeared at both the Hamburg State Opera and the Vienna State Opera in 1981 as the Emperor in Die Frau ohne Schatten by Richard Strauss. In 1983, he appeared as Max in Weber's Der Freischütz at the Bregenz Festival. The same year, he made his U.S. debut as Erik at the Lyric Opera of Chicago. In 1984 he took part in the Hamburg State Opera's tour of Japan. In 1986 he appeared as Florestan in Beethoven's Fidelio at the Metropolitan Opera, opposite Hildegard Behrens in the title role, returning in 1989 as Siegmund and in 1990 as the Emperor, a role which he had also performed for his 1987 debut at the Royal Opera House. In 1996, he appeared as Loge in Wagner's Das Rheingold at the Opéra de Marseille. In addition to his opera activities, Schunk has also performed successfully in concerts.

Input: Consider Input: Question: How old was the Liberal Unionist MP when he died? Passage:Morton first stood for Parliament at the 1885 general election, when he contested Hythe, and was unsuccessful again in Christchurch at the 1886 election. He won a seat three years later, when he was elected at a by-election in October 1889 as the Member of Parliament (MP) for Peterborough, after the death of the Liberal Unionist MP John Wentworth-FitzWilliam, becoming the 81st new MP since the general election in 1886. His victory was unexpected, and when the result was declared he said that he hoped his victory would be seen as a gesture of conciliation Ireland. He was re-elected in 1892, and raised in Parliament the issue of the appointment of Justices of the Peace (magistrates) in April 1893. In November that year, 280 Gladstonian MPs met the Lord Chancellor, Lord Herschell, in the House of Lords to discuss the system. Morton led the response to the Lord Chancellor's explanation and defence of the existing system of appointment, and denounced the reliance on advice from Lord Lieutenants who were entirely dependent on what Morton called "class cliques". He was also a member of a Select Committee set up to examine the accommodation provided for members and officials of the House of Commons. Great Western Railway

Input: Consider Input: Question: How many times has Akira appeared on The Simpsons? Passage:The episode was written by Nell Scovell and directed by Wes Archer. In the episode, Bart and Lisa sneak into the sushi bar's karaoke room and sing the theme song to the 1971 film Shaft, "Theme from Shaft". The Fox network censors originally did not want the staff to use the song because they thought the lyrics were too obscene for television. In order to prove the censors wrong and show that it could appear on television, the staff dug up footage from an old Academy Awards ceremony at which the song was performed by Isaac Hayes. When the chef at the sushi bar finds out Homer has been poisoned, he yells at his apprentices in Japanese. The staff wanted the language they spoke to be actual Japanese, so they hired a Japanese actor who translated the lines for them. The episode introduced the character Akira, who has appeared many times later on the show. American actor George Takei provided the voice of Akira, although the character was voiced in later episodes by Hank Azaria. The episode featured many other guest appearances; Larry King as himself; Sab Shimono as the sushi bar chef; Joey Miyashima as Toshiro, the apprentice chef who slices up the fugu; and Diane Tanaka as hostess of the bar. King's role was first offered to American singer Bruce Springsteen, but he turned it down. According to showrunner Sam Simon, actor William Shatner also rejected the part.
