Example Input: Question: How many games did the Los Angeles Rams win the last year Cowan played for them? Passage:Charles Edward Cowan (June 19, 1938 in Braeholm, West Virginia – April 29, 1998 in Los Angeles, California) was an American football offensive tackle who played fifteen seasons in the National Football League with the Los Angeles Rams from 1961 to 1975. Cowan was a huge intimidating presence on the left of Tom Mack, a member of the Pro Football Hall of Fame, from 1966 to 1975, forming a potent left side of the offensive line, with help from Ken Iman at center from 1965 to 1975. In that 1961 to 1975 span, the Rams made the playoffs 5 times (1967,1969,1973,1974,1975), reaching the NFC championship game of the 1974-75 NFL playoffs and the 1975-76 NFL playoffs, but losing to the Minnesota Vikings and to the Dallas Cowboys, respectively. In the 1974 divisional round, the Rams defeated the Washington Redskins, as Cowan was successful against the opposing the right defensive end Verlon Biggs. In the 1975 divisional round, Doug France started in his place as the Rams defeated the St. Louis Cardinals. Cowan came back to play against the Cowboys, his final game, as the Rams could not get past them. Cowan was replaced by Doug France in 1976.

Example Input: Question: Who was the elder of the two men De La Pole escaped from when he fled to France? Passage:He was appointed Chancellor in 1383, and created Earl of Suffolk in 1385, the first of his family to hold any such title (the earldom had become extinct in 1382 on the death of William de Ufford). However, in the late 1380s his fortunes radically altered, in step with those of the king. During the Wonderful Parliament of 1386 he was impeached on charges of embezzlement and negligence, a victim of increasing tensions between Parliament and Richard. He was the first official in English history to be removed from office by the process of impeachment. Even after this disgrace, he remained in royal favour, although soon fell foul of the Lords Appellant. He was one of a number of Richard's associates accused of treason by the Appellants in November 1387. After the Appellants' victory at Radcot Bridge (December 1387) and before the so-called Merciless Parliament met in February 1388, De La Pole shrewdly fled to Paris, thus escaping the fate of Sir Nicholas Brembre and Chief Justice Robert Tresilian. He remained in France for the remainder of his life. Sentenced in his absence, his title and estates were stripped from him.
