Problem: Background: Howard Brush Dean III (born November 17, 1948) is an American physician, author and retired politician who served as the 79th Governor of Vermont from 1991 to 2003 and Chair of the Democratic National Committee (DNC) from 2005 to 2009. Dean was a candidate for the Democratic nomination in the 2004 presidential election. His implementation of the fifty-state strategy as head of the DNC is credited with the Democratic victories in the 2006 and 2008 elections. Afterward, he became a political commentator and consultant to McKenna Long & Aldridge, a law and lobbying firm.
Context: Dean was born in East Hampton, New York, to Andree Belden (nee Maitland), an art appraiser, and Howard Brush Dean, Jr., an executive in the financial industry.  He is the eldest of four brothers, including Jim Dean, Chair of Democracy for America, and Charles Dean, who was captured by the Pathet Lao and executed by the North Vietnamese while traveling through Southeast Asia in 1974.  Howard's father worked at the stock brokerage firm of Dean Witter. The family was quite wealthy, Republican, and belonged to the exclusive Maidstone Golf Club in East Hampton. As a child he spent much of his time growing up in East Hampton; the family built a house on Hook Pond there in the mid-1950s. There the boys- Howard, Charlie, Jim and Bill- "rode bikes, played with a model train set, [and] built elaborate underground forts." While in New York, the family had a three-bedroom apartment on the Upper East Side along Park Avenue.  Howard attended the Browning School in Manhattan until he was 13, and then went to St. George's School, a preparatory school in Middletown, Rhode Island. In September 1966, he attended Felsted School, UK, for one school year after winning an English Speaking Union scholarship.  Political opponents have been reluctant to seize upon Dean's privileged early life. UPI quoted one of Dean's friends in his youth as saying, "By Hamptons standards, the Deans were not rich. No safaris in Africa or chalets in Switzerland. Howard's father went to work every day. He didn't own a company, or have a father or grandfather who founded one, as mine did." Peggy Noonan wrote in the Wall Street Journal that  "he doesn't seem like a WASP. I know it's not nice to deal in stereotypes, but there seems very little Thurston Howell, III, or George Bush, the elder, for that matter, in Mr. Dean.... He seems unpolished, doesn't hide his aggression, is proudly pugnacious. He doesn't look or act the part of the WASP...It will be harder for Republicans to tag Mr. Dean as Son of the Maidstone Club than it was for Democrats to tag Bush One as Heir to Greenwich Country Day. He just doesn't act the part."
Question: Where did he attend at age 13?
Answer: went to St. George's School, a preparatory school in Middletown, Rhode Island. In September 1966, he attended

Problem: Background: Wishbone Ash are a British rock band who achieved success in the early and mid-1970s. Their popular albums included Wishbone Ash (1970), Pilgrimage (1971), Argus (1972), There's the Rub (1974), and New England (1976). Wishbone Ash are noted for their extensive use of the harmony twin lead guitar format which had been attracting electric blues bands since Jeff Beck and Jimmy Page had played together in the Yardbirds in 1966. Their contributions helped Andy Powell and Ted Turner to be voted "Two of the Ten Most Important Guitarists in Rock History" (Traffic magazine 1989), and to appear in the "Top 20 Guitarists of All Time" (Rolling Stone).
Context: Turner was replaced by bassist and vocalist John Wetton, formerly of Family, King Crimson, Roxy Music, Uriah Heep and UK. Number the Brave was released in April 1981 and featured Wetton's lead vocals on just one song, although during album sessions he had offered songs such as "Here Comes the Feeling" that would eventually sell millions when released on Asia's 1982 debut album. Wetton did not continue with Wishbone Ash beyond the album sessions and rejoined Asia.  Wetton was replaced on the Number the Brave tour by the former Uriah Heep bassist Trevor Bolder. Also joining the band was female backing vocalist, Claire Hamill, who had sung on both the Just Testing and Number the Brave albums. In 1982, after Hamill's departure, the band experimented with heavy metal on the Twin Barrels Burning album. It became the highest charting Wishbone Ash album in years (UK #22).  Bolder left the group to rejoin Uriah Heep in 1983, to be replaced by bassist/vocalist Mervyn Spence (ex-Trapeze). The group continued with a heavy metal side on 1985's Raw to the Bone, which became the first Wishbone Ash album not to make the charts. Not long after, Wisefield left after serving as guitarist in the band for eleven years, going on to a varied career that would include work with Tina Turner, Joe Cocker, Roger Chapman, Jeff Wayne and the Queen musical We Will Rock You. He was replaced by Jamie Crompton, who in turn was succeeded briefly by Phil Palmer. Early in 1986, Mervyn Spence quit as well, to be replaced by ex-Kinks bassist Andy Pyle.
Question: who replaced Bolder?
Answer:
bassist/vocalist Mervyn Spence (ex-Trapeze).
