Teacher: Now, understand the problem? Solve this instance: Question: How old was Takanosato when he reached yokozuna ranking? Passage 1:A former amateur champion at Nihon University, he turned professional at the age of 23, joining Kasugano stable in March 1981. He reached the top makuuchi division in September 1983, and in 1984 he earned his first special prize for Fighting Spirit, and defeated Takanosato in his first ever bout against a yokozuna to earn his first of his three kinboshi. He spent most of 1985 in the second jūryō division, but in 1986 made the san'yaku ranks at komusubi. In November 1987 he scored 10–5 from the maegashira 6 ranking, defeating two ōzeki and winning the Technique Prize. This earned him promotion to his highest rank of sekiwake for the following tournament in January 1988. However, by the end of the year he was in jūryō again due to injury problems. He won the jūryō yūshō on two occasions in 1989 and won promotion back to the top division. After missing the September 1990 tournament he fell to jūryō again and made only one more appearance in makuuchi before retiring in May 1992 at the age of 34.
 Passage 2:Tanaka subsequently teamed with Mitsu Arakawa in the WWF, acquiring the International Tagteam Championship; losing it at Madison Square Garden to Tony Marino and Victor Rivera. The team of Tanaka and Fuji won three WWWF World Tag Team Championships, with Blassie as manager for the third reign and The Grand Wizard as manager for the first two. They first won the belts from Sonny King and Chief Jay Strongbow on June 27, 1972 in Philadelphia, PA at a House show. They lost the belts to Haystacks Calhoun and Tony Garea on May 30, 1973, again at a Hamburg house show, but regained them on September 11, 1973 in Philadelphia, PA before losing them again to Tony Garea and Dean Ho on November 14, 1973, again in Hamburg. Their third win came on September 27, 1977 at a Philadelphia house show when they defeated Tony Garea and Larry Zbyszko in a tournament final for the vacant belts, holding them until March 14, 1978 when they lost the titles to Dino Bravo and Dominic DeNucci in Philadelphia. This third reign set a record for number of championship reigns which would be equalized by The Wild Samoans in 1983, Demolition in 1990, Money Inc. in 1993, The Quebecers in 1994 and The Smoking Gunns in 1996, but not bettered until The New Age Outlaws won a fourth reign in 1999.
 Passage 3:However, when tried at for the first time at hooker in 1992 against Manly at Carlaw Park, McCormack impressed immediately for his workrate and his ability to dart out of the dummy half position. McCormack was selected to represent New South Wales in game I of the 1992 State of Origin series and game II of the 1993 series when he replaced Benny Elias as hooker. Eventually becoming captain of the Knights, he was signed by Newcastle's new cross-town rivals the Hunter Mariners for the 1997 Super League (Australia) season. After that McCormack moved to the Super League to play for English club Wigan Warriors. He was named in 1998's Super League Dream Team. He also played at hooker for Wigan Warriors in their 1998 Super League Grand Final victory over Leeds Rhinos.
