question:
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.

question:
Question: Which county that I-24 goes through has the highest population? Passage:I-24 continues southeast through the rapidly growing suburbs of Nashville, and crosses into Rutherford County near the city of LaVergne, where there are three exits. Beginning at this point, I-24 is relatively straight and flat for most of its distance through Middle Tennessee. The straightest stretch of highway in Tennessee is located on I-24 between Lavergne and eastern Murfreesboro, where the route is perfectly straight for about fifteen miles, although the median widens and narrows. Four miles later is an interchange with SR 102, which connects to Smyrna and the Nissan Motor Manufacturing Plant. Another four miles later is an interchange with Interstate 840, the outer southern beltway around Nashville, and I-24 enters Murfreesboro, the largest suburb of Nashville. In Murfreesboro, I-24 has interchanges with SR 96 (which connects of Franklin), SR 99 (New Salem Highway), and US 231 (which connects to Lebanon and Shelbyville), respectively, and at the final Murfreesboro exit (US 231), the HOV lane designation ends, and I-24 narrows to six lanes and then four lanes a short distance later. Three miles later is an interchange with the Joe B. Jackson Parkway, which serves as an outer beltway around southeast Murfreesboro. I-24 then enters a more rural area, and at exit 97 has an interchange with SR 64, which connects to Shelbyville. I-24 then curves to the south, then the east, briefly enters Bedford County, and then Coffee County. At exit 105 is an interchange with US 41, and five miles later I-24 enters Manchester, where it has interchanges with SR 53, SR 55, and US 41, respectively. I-24 continues through a rural, largely agricultural area where it crosses into Grundy County and has an interchange with US 64 and SR 50.

question:
Question: Which town that Dunkelman fought in has the largest current population? Passage:He was back in Toronto in 1939 when the Second World War broke out. He attempted to join the Royal Canadian Navy (RCN), but anti-semitism in the RCN at the time precluded a naval career. Instead Dunkelman enlisted as a private with The Queen's Own Rifles of Canada; as the war progressed he rose from Private to Major. He was in the second wave to land on Juno beach, the Canadian beach in the Normandy landings on D-Day 6 June 1944. During his career with the regiment he earned numerous commendations and a Distinguished Service Order (DSO) for his service in the Hochwald campaign. He also fought in the difficult earlier campaigns in northern France, Belgium, the Netherlands and Germany, including bloody battles at Caen, Falaise, and the Battle of the Scheldt Estuary that led to the critical port of Antwerp.
