Question: Did any Giants players play in the 1984 All-Star game? Passage:The 2007 Major League Baseball All-Star Game was the 78th midseason exhibition between the all-stars of the American League (AL) and the National League (NL), the two leagues comprising Major League Baseball. The game was held on July 10, 2007, at AT&T Park, the home of the NL's San Francisco Giants. It marked the third time that the Giants hosted the All Star Game since moving to San Francisco for the 1958 season. The 1961 and 1984 All Star Games were played at the Giants former home Candlestick Park, and the fourth overall in the Bay Area, with the Giants bay area rivals the Oakland Athletics hosting once back in 1987, and the second straight held in an NL ballpark.

Question: How old was Hokutoumi when he defeated Jingaku Takashi by making him stumble out of the dohyo? Passage:He came from the same area of Japan as future stable-mates Sakahoko and Terao. He was fond of kendo at school. He joined Izutsu stable in 1977, and first reached a sekitori rank in July 1982 when he was promoted to the juryo division. He first made the top makuuchi division in January 1983 but posted a losing record of 4–11 and so was immediately demoted. He won promotion back to the top division in January 1984, and remained there for virtually all of the rest of his career. In September 1984 he defeated a yokozuna for the first time when he upset Kitanoumi in one of the latter's final tournaments. He made the sanyaku ranks for the first time in November 1987 when he reached komusubi, but he proved to be out of his depth and scored only two wins against thirteen losses. He made komusubi once more in September 1990 at the age of 30, but again struggled, winning only three bouts. He suffered from stage fright, losing weight during tournaments because of stomach upsets. This affected his performance against top ranked wrestlers – he stumbled out of the dohyo in a match against Hokutoumi in September 1990 with his opponent barely having to touch him. He was restricted by a foot problem as well as digestive illness towards the end of his career. After 46 consecutive tournaments in the top division he was demoted to juryo after scoring only 4-11 at maegashira 15 in the July 1991 tourney, and he pulled out of the following tournament with a knee injury after fighting only one match. This brought to an end his streak of 1036 consecutive matches from sumo entry. He announced his retirement shortly afterwards.

Question: Who was the lead singer on the singles Money and Us and Them? Passage:The record builds on ideas explored in Pink Floyd's earlier recordings and performances, while omitting the extended instrumentals that characterised their earlier work. A concept album, its themes explore conflict, greed, time, death, and mental illness, the latter partly inspired by the deteriorating health of founding member Syd Barrett, who departed the group in 1968. The group used recording techniques such as multitrack recording, tape loops, and analogue synthesisers. Snippets from interviews with the band's road crew, as well as philosophical quotations, were also used. Engineer Alan Parsons was responsible for many sonic aspects and the recruitment of singer Clare Torry, who appears on "The Great Gig in the Sky". The sleeve, which depicts a prism spectrum, was designed by Storm Thorgerson, following keyboardist Richard Wright's request for a "simple and bold" design, representing the band's lighting and the record's themes. The album was promoted with two singles: "Money" and "Us and Them".
