Question: Has the maple leaf been used on any other coat of arms or country flags besides in Canada? Passage:The maple leaf has been used as a Canadian emblem since the 18th century. It was first used as a national symbol in 1868 when it appeared on the coat of arms of both Ontario and Quebec. In 1867, Alexander Muir composed the patriotic song "The Maple Leaf Forever", which became an unofficial anthem in English-speaking Canada. The maple leaf was later added to the Canadian coat of arms in 1921. From 1876 until 1901, the leaf appeared on all Canadian coins and remained on the penny after 1901. The use of the maple leaf by the Royal Canadian Regiment as a regimental symbol extended back to 1860. During the First World War and Second World War, badges of the Canadian Forces were often based on a maple leaf design. The maple leaf would eventually adorn the tombstones of Canadian military graves.

Question: Who is the wife of the Tigers pitcher who was name World Series MVP? Passage:The 2012 World Series was the championship series of Major League Baseball's (MLB) 2012 season. The 108th edition of the World Series, the series was a best-of-seven playoff between the National League (NL) champion San Francisco Giants and the American League (AL) champion Detroit Tigers; the Giants won in a four-game sweep. This marked the Giants' seventh World Series title in franchise history, their second in San Francisco (they won five in New York), and their second in a three-year period (2010–2012). Their World Series sweep was the first by an NL team since the Cincinnati Reds swept the Oakland Athletics in the 1990 series and the first NL sweep not by the Reds since 1963, when the Los Angeles Dodgers swept the New York Yankees. This was also the first World Series since 1988 to feature both of that year's League MVPs (Miguel Cabrera for the AL and Buster Posey for the NL). The Giants' Pablo Sandoval, who in Game 1 tied a record by hitting three home runs in one World Series game, two off Tigers' ace pitcher Justin Verlander, was named the World Series Most Valuable Player (MVP).
