Question: In what country did Boreal make his first appearance outside Germany? Passage:On his first race of 2002, Boreal made his first appearance outside Germany when he contested the Dubai Sheema Classic at Nad Al Sheba Racecourse on 23 March. Ridden by Kieren Fallon, he stayed on strongly in the straight and finished third behind Nayef and the New Zealand gelding Hades with the other beaten horses including Marienbard and Tobougg. On 7 June, the colt was sent to England and attempted to become the first German-trained horse to win the Coronation Cup over one and a half miles at Epsom Racecourse. Racing on soft ground, he started 4/1 third favourite behind Kutub (Preis von Europa, Gran Premio del Jockey Club, Singapore Gold Cup), and Storming Home. The other three runners were Marienbard, Zindabad (Yorkshire Cup), and Pawn Broker (Arc Trial). Fallon positioned the German challenger just behind the leader Zindabad before taking the lead entering the straight and tracking across to the stands-side (outside) rail. Boreal went clear of his rivals in the last quarter mile and won by three and a half lengths from Storming Home with Zindabad six lengths back in third. After training the first German winner at Group One level in Britain since Star Appeal took the 1975 Eclipse Stakes, Schiergen said, "He travels smoothly on good ground but is more at home on soft. It's a special thrill to have a winner in Britain, and extra-special when it's a Group 1 at the home of the Derby."

Question: How long had A&M Records been in business at the time the Carpenters signed a contract with them? Passage:The siblings were born in New Haven, Connecticut, and moved to Downey, California, in 1963. Richard took piano lessons as a child, progressing to California State University, Long Beach, while Karen learned the drums. They first performed together as a duo in 1965 and formed the jazz-oriented Richard Carpenter Trio followed by the middle-of-the-road group Spectrum. Signing as Carpenters to A&M Records in 1969, they achieved major success the following year with the hit singles "(They Long to Be) Close to You" and "We've Only Just Begun". Subsequently, the duo's brand of melodic pop produced a record-breaking run of hit recordings on the American Top 40 and Adult Contemporary charts, and they became leading sellers in the soft rock, easy listening and adult contemporary music genres. The Carpenters had three number-one singles and five number-two singles on the Billboard Hot 100 and fifteen number-one hits on the Adult Contemporary chart, in addition to twelve top-10 singles. They have sold more than 90 million records worldwide, making them one of the best-selling music artists of all time. The duo toured continually during the 1970s, which put them under increased strain; Richard took a year off in 1979 after he had become addicted to Quaaludes, while Karen suffered from anorexia nervosa.

Question: Where was the author that Whittier College was named for born? Passage:Named after Whittier College in Whittier, California, the ship was built at the California Shipbuilding Yard (Calship) in Los Angeles, California in just 82 days and was delivered on 18 July 1945. The Whittier City and Whittier College was named for author John Greenleaf Whittier. SS Whittier Victory was the 798 of the 10,500-ton class known as Victory ships, built under the Emergency Shipbuilding program. Victory ships were designed to replace the earlier Liberty ships. Liberty ships were designed to be used solely for World War II. Victory ships were designed to last longer and serve the US Navy after the war. The Victory ship differed from a Liberty ship in that it was faster, longer, wider, taller, and had a thinner stack set farther toward the superstructure and a long raised forecastle. She was a United States Merchant Marine ship operated by the Moore-McCormack Lines for World war 2. She loaded up cargo at a few west coast ports and streamed to support the Pacific War. SS Whittier Victory delivered supplies in the island-hopping campaigns towards the Empire of Japan. As a Merchant Marine ship, she had a civilian crew to man the ship and US Navy Armed Guards to man the deck guns.
