Boston traded him in 1972 to the California Golden Seals of the NHL. He played there until the end of the next season (1972–73) when he left the NHL for the World Hockey Association (WHA) and played for the Minnesota Fighting Saints. In 1975–76 Smith returned to the NHL to play for the St. Louis Blues. He would remain with the Blues until the 1976–77 NHL season when he returned to the Boston Bruins. In 1980 Rick Smith would leave Boston to play one more NHL season split between the Detroit Red Wings (11 games) and the Washington Capitals (40 games).

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 Andō Hiroshige (Hōeidō edition) from 1831 to 1834 depicts a Yahagibashi, one of the few bridges permitted by the Tokugawa shogunate on the Tōkaidō, 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.
 Links: a. Castle town b. Okazaki Castle c. Toyohashi d. Meiji Restoration

Output: b


Input: Consider Input: Question: Where did the Edmonton Oilers play their home games when Jim Matheson finished his tenure as their beat writer? Passage:Matheson was born on April 7, 1949 in Winnipeg, Manitoba to Jack and Peggy Matheson. Matheson had an intention to follow the footsteps of his father, Jack, a long-time sports editor for the Winnipeg Tribune. He graduated from the University of Manitoba with a degree in political science, and while in school, worked a part-time night shift with the Tribune. He got his first job upon completing school with the Regina Leader-Post, but moved west to Edmonton, Alberta six months later. Upon moving to Edmonton, Matheson got a job with the Edmonton Journal in 1970. He initially covered local curling and university sports, but quickly switched to hockey, when, in 1973, Edmonton was granted a WHA franchise, the Edmonton Oilers. Matheson became the beat writer for the Oilers then, and continued when the Oilers joined the NHL in 1979. He spent countless hours covering the team and its five Stanley Cups, and completed more than 300 stories per winter. In addition to writing, Matheson also was a part of the CFRN radio broadcasting team that covered the Oilers. After 24 years, he completed his tenure as beat writer for the Oilers in 1997. He now continues to write for the Edmonton Journal covering the NHL and the Oilers.
