Input: Consider Input: Question: What year was the castle that served as the headquarters for the Okazaki Domain built? Passage:Okazaki-shuku was a part of the flourishing castle town surrounding Okazaki Castle, the headquarters for Okazaki Domain. The classic ukiyo-e print by Ando Hiroshige (Hoeido edition) from 1831 to 1834 depicts a Yahagibashi, one of the few bridges permitted by the Tokugawa shogunate on the Tokaido, and one of the longest bridges built in Japan during the early Edo period. Okazaki Castle is depicted in the distance on the far shore of the river. Following the Meiji restoration, with the construction of railroads, the route of what became the Tokaido Main Line was laid down through the nearby village of Hane ( Hane-mura) to the south. Unlike Goyu-shuku and Akasaka-juku, but this did not cause a huge economic decline to Okazaki-shuku. There was a horse-drawn rail line connecting Okazaki to the train station, as well as a teachers' school, which kept the town alive. On the other hand, Okazaki was not able to compete with the growth of Toyohashi, which was located directly on the railway, and which gained city-status first. Because of fires during World War II and the subsequent rebuilding of Okazaki in the post-war years, there are few remnants of the post town remaining today.

Input: Consider Input: Question: How old was Steven Schumacher the year that Michael Symes signed for the League One side with him? Passage:Crewe manager Dario Gradi decided not to offer a contract to Symes, who instead spent a period on trial at Bradford City, which included an 81 pre-season friendly win over Farsley Celtic. He signed for the League One side in July 2004 with fellow former Everton trainee Steven Schumacher, with whom he lived during his spell at Bradford. Symes made his Bradford debut in a 21 defeat at Hartlepool United on the opening day of the 200405 season. Three days later he missed a late penalty which would have secured Bradford victory over Peterborough United in a game in which Symes was also booked. Symes was dropped from the first team after Bradford signed Dele Adebola. When Bradford were allowed special dispensation to sign Neil Roberts, Bradford tried to give Symes a loan transfer to Darlington but the deal was blocked by the Football League. The following month, Symes scored his first goals for Bradford when he came off the bench at half-time to score twice in a 31 victory over Sheffield Wednesday on 23 October 2004. They were the only goals he scored that season from just 15 games.
