Input: Consider Input: Question: How much profit did AMECON make the year that the Australian government awarded them the Anzac contract? Passage:The Anzac class originated from RAN plans to replace the six River-class destroyer escorts with a mid-capability patrol frigate. The Australian shipbuilding industry was thought to be incapable of warship design, so the RAN decided to take a proven foreign design and modify it. Around the same time, the Royal New Zealand Navy (RNZN) was looking to replace four Leander-class frigates; a deterioration in New Zealand-United States relations, the need to improve alliances with nearby nations, and the commonalities between the RAN and RNZN ships' requirements led the two nations to begin collaborating on the acquisition in 1987. Tenders were requested by the Anzac Ship Project at the end of 1986, with 12 ship designs (including an airship) submitted. By August 1987, the tenders were narrowed down in October to Blohm + Voss's MEKO 200 design, the M class (later Karel Doorman class) offered by Royal Schelde, and a scaled-down Type 23 frigate proposed by Yarrow Shipbuilders. In 1989, the Australian government announced that Melbourne-based shipbuilder AMECON (which became Tenix Defense) would build the modified MEKO 200 design. The Australians ordered eight ships, while New Zealand ordered two, with an unexercised option for two more.

Input: Consider Input: Question: How long had Nomme Kalju been a team when Teever signed with them? Passage:After his contract expired in May 2012, Teever returned to Estonia and joined Nõmme Kalju's beach soccer team. He was also part of Estonian national team that played 2013 FIFA Beach Soccer World Cup qualification matches in Moscow in the beginning of July. Teever then signed a year-and-a-half long contract with Levadia and was instantly added to the UEFA Europa League squad. He also got offers from Finland and Germany, but decided to stay in Estonia so he could have better chance to return to the national team. On 19 July 2012, Teever made his debut for Levadia when he came on as a second-half substitute in a Europa League match against Cypriot side Anorthosis. He opened his goal scoring tally on his Meistriliiga debut on 23 July 2012, when his injury time free kick found the net against Tallinna Kalev.

Input: Consider Input: Question: What man was the lead guitarist for the shortest amount of times? Passage:The Yardbirds are an English blues rock band from London. Formed in May 1963, the group originally included lead vocalist Keith Relf, lead guitarist Anthony "Top" Topham, rhythm guitarist Chris Dreja, bassist Paul Samwell-Smith and drummer Jim McCarty. In October, Topham was replaced by Eric Clapton. He remained until 13 March 1965, when he left due to creative disagreements. Clapton recommended Jimmy Page to replace him, but he declined and Jeff Beck took over. Page later joined on bass the following June, after Samwell-Smith abruptly quit; Dreja later took over the role, allowing Page to join Beck on guitar. This lineup was short-lived, however, as Beck left in November 1966. The group continued as a four-piece until July 1968, when Relf and McCarty left due to creative differences, primarily with Page. Dreja initially remained, but by August Page formed a new group with vocalist Robert Plant, bassist John Paul Jones and drummer John Bonham, who later renamed themselves Led Zeppelin.
