[Q]: Question: In what year was the royal house's name change? Passage:The programme explores the lives of King George V and Queen Mary, and their attempts at modernising the British Monarchy in response to the massive social changes during and following World War I. The first episode recalls how, fearing anti-German sentiment, the royal house name was changed by King George from the House of Saxe-Coburg and Gotha to the House of Windsor. The series also examines the personal lives of the couple, delving into their relationships with their children, and with each other. The marriage between George and Mary was an arranged marriage, occurring only because Prince Albert Victor, George's brother and Mary's original fiance, died from influenza. George V is presented in the series as a disciplinarian, who strictly punished his children, but was known to be much more loving to his granddaughter, Queen Elizabeth II.

[Q]: Question: How did the Arizona Diamondbacks defeat in the World Series? Passage:This article is about the history of the Arizona Diamondbacks. The Diamondbacks (often shortened as the D-Backs), an American professional baseball team based in Phoenix, Arizona, were formed in 1998, based at Bank One Ballpark. This followed five years of preparation under the leadership of Jerry Colangelo. The Diamondbacks won the World Series championship in 2001, becoming the fastest expansion team in the Major Leagues to win a championship, doing so in only the fourth season since inception in 1998. Financial difficulties were then encountered and the home field was renamed to Chase Field in 2005, as a result of Bank One Corporation's merger with JPMorgan Chase & Co. After a lean period the team won the National League West division in 2011.
