Passage:Jack Eugene Jensen (March 9, 1927 – July 14, 1982) was an American right fielder in Major League Baseball who played for three American League (AL) teams from 1950 to 1961, most notably the Boston Red Sox. He was named the AL's Most Valuable Player (MVP) in after hitting 35 home runs and leading the league with 122 runs batted in (RBIs); he also led the league in RBIs two other years, and in triples and stolen bases once each. Respected for his throwing arm, he won a Gold Glove Award and led the AL in assists and double plays twice each.

Example Input: Question: Which of the members who escaped with John Blake Dillion to France was the youngest? Passage:John Mitchel, the most committed advocate of revolution, had been arrested early in 1848, then convicted on the purposefully–created charge of Treason-felony. He was sentenced to transportation to Bermuda, where he joined other convicts labouring on the construction of the Royal Naval Dockyard on Ireland Island. He was subsequently sent to Van Diemen's Land (in present-day Tasmania, Australia) where he was soon to be joined by other leaders, such as William Smith O'Brien and Thomas Francis Meagher who had both been arrested after Ballingarry. John Blake Dillon escaped to France, as did three of the younger members, James Stephens, John O'Mahony and Michael Doheny. Meagher and John Mitchel (who had been transported there before for political activities) both managed to escape and emigrate to the United States in the early 1850s. They served on opposite sides of the American Civil War: Meagher serving with the Union, for which he recruited and commanded the Irish Brigade, and Mitchel allying himself with the South and living there, sending three sons to fight with the Confederacy.
