Question: How old was Whitehouse when he defeated Chafee? Passage 1:Chafee was the only Republican in the Senate to vote against authorization of the use of force in Iraq in the lead-up to the Iraq War. He was defeated in his 2006 reelection bid by Democrat Sheldon Whitehouse. Chafee subsequently shifted his affiliation towards the Democratic Party by first endorsing Barack Obama in the 2008 presidential election, running as an independent for Governor of Rhode Island in 2010, serving as the co-chair of Obama's 2012 re-election campaign, and then finally officially switching his registration to the Democratic Party in May 2013. In 2015, he sought nomination to be the Democratic Party candidate in the 2016 presidential election, but withdrew prior to the primaries and later endorsed Hillary Clinton. In 2019, Chafee expressed interest in running in the Libertarian primary for President in the 2020 election.
 Passage 2:The NASL first staged an indoor tournament in 1971 at the St. Louis Arena with a $2,800 purse. After a couple of years of experimenting, including a three-city tour by the Red Army team from Moscow in 1974, the league again staged tournaments in 1975 and 1976. For many years Tampa Bay owner George W. Strawbridge, Jr. lobbied his fellow owners to start up a winter indoor season, but was always stone-walled. For several years, his Rowdies and several other teams used winter indoor "friendlies" as part of their training and build-up to the outdoor season. In the meantime, pressed by the rival Major Indoor Soccer League (MISL), which inaugurated play in 1978, two-day mini-tournaments like the Skelly Invitational and the NASL Budweiser Invitational were held with varying degrees of success. The NASL finally started a full indoor league schedule, a 12-game season with 10 teams, in 1979–80. For the 1980–81 season, the number of teams playing indoor soccer increased to 19 and the schedule grew to 18 games. The schedule remained at 18 games, but the teams participating decreased to 13 for the 1981–82 season. The league canceled the 1982–83 indoor season and three teams (Chicago, Golden Bay, and San Diego) played in the MISL for that season. Four other teams (Fort Lauderdale, Montreal, Tampa Bay and Tulsa) competed in a short NASL Grand Prix of Indoor Soccer Tournament in early 1983. The NASL indoor season returned for 1983–84 with only seven teams but a 32-game schedule.
 Passage 3:Charles-Joseph Lamoral, 7th Prince de Ligne in French; in German Karl-Joseph Lamoral 7. Fürst von Ligne (also known as Karl Fürst von Ligne or Fürst de Ligne): (23 May 1735 – 13 December 1814) was a Field Marshal, inhaber of an infantry regiment, prolific writer, intellectual, member of the princely family of Ligne, and Habsburg Austrian subject. He fought as a field officer during several famous battles during the Seven Years' War and briefly returned to military duty in the War of the Bavarian Succession. He performed an important diplomatic mission to Catherine the Great in 1787 and led troops against the Ottoman Empire at Belgrade in 1789. Beginning in the 1770s, he authored an impressive volume of work. After his estates in the Austrian Netherlands were lost to France during the War of the First Coalition, he lived in Vienna. All three of his sons died before him, but his wife and four daughters all outlived him. His grandson, the 8th Prince, became a Belgian statesman.
