In this task, you're given a passage, further information available on a particular linked term from the statement, and an answer term. Your job is to generate a question that can use the information provided to obtain the given answer. You should use the information on both passage and link information to create the question. Note that the answer to the question should be exactly the given answer, and if the answer is none, the answer to the question shouldn't be obtainable from the passage or linked information.

Input: Consider Input: Passage: When Isabella first became queen, she was only three years old. The queen mother, Maria Christina of the Two Sicilies, served as regent. The first and foremost political division of the Isabeline era was between Carlists and Cristinos (or Isabelinos), the former being supporters of Infante Carlos, Count of Molina, a rival claimant to the throne and the latter being supporters of Maria Christina and Isabella. The former supported absolute monarchism and the traditionalism of the Antiguo Regimen ("Old Regime"); they were uniformly close to the Roman Catholic Church, and generally clericalist. The latter were generally supporters of constitutional monarchy (although some, including Maria Christina herself, were more inclined toward enlightened absolutism); they were liberals of one stripe or another, ranging from liberal conservatives and those whose liberalism was strictly economic to social liberals. In the 1830s, these two groups faced off in the First Carlist War, which the Cristinos won. The terms of surrendernotably the Convention of Vergaraleft an opportunity for relatively moderate Carlists to continue to play a role in the country's politics, and many did so over the ensuing decades.
Link Information: In the 1830s, these two groups faced off in the First Carlist War, which the Cristinos won. The terms of surrendernotably the Convention of Vergara Answer: 6

Output: How many years after the war began in the 1830s was the terms of surrender signed?

Input: Consider Input: Passage: A tunnel diode or Esaki diode is a type of semiconductor diode that has negative resistance due to the quantum mechanical effect called tunneling. It was invented in August 1957 by Leo Esaki, Yuriko Kurose, and Takashi Suzuki when they were working at Tokyo Tsushin Kogyo, now known as Sony. In 1973, Esaki received the Nobel Prize in Physics, jointly with Brian Josephson, for discovering the electron tunneling effect used in these diodes. Robert Noyce independently devised the idea of a tunnel diode while working for William Shockley, but was discouraged from pursuing it. Tunnel diodes were first manufactured by Sony in 1957, followed by General Electric and other companies from about 1960, and are still made in low volume today.
Link Information: In 1958, the company changed its name to "Sony". Answer: 1958

Output: When did Tokyo Tsushin Kogyo change its name?

Input: Consider Input: Passage: Samuel Perry (c.1864 19 March 1930) was the son of John and Harriett Perry (ca.1834 24 September 1918) of Shropshire, England, and the brother of Rev. Isaiah Perry (18541911). He was apprenticed as an iron worker to the Coalbrookdale Company, where he trained as an engineer. At the age of 22, around 1886, he followed his brother to Gawler, South Australia, where he found employment at James Martin's "Phoenix Foundry", living with the Roediger family at nearby Buchfelde (later named Loos). He next worked at Port Adelaide, then as foreman for John Danks & Son of Melbourne. He returned to Adelaide and started his own business with the purchase of James Wedlock's "Cornwall Foundry", the transfer of that factory to new premises Perry Engineering at Mile End, and the purchase of the James Martin & Co. workshops in Gawler. He took on his nephew Frank Perry, who became managing director and company chairman on his death.
Link Information: The effective foundation day of Port Adelaide was 6 January 1837. Answer: 1837
Output: When was the company that Perry worked for after being employed at "Phoenix Foundry" founded?
