Question: Which team won more games the year Cowan started with the Rams, the Vikings or the Cowboys? 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.

Question: Which of East 17's singles stayed in the top 10 for the least number of weeks? Passage:Twenty-five artists scored multiple entries in the top 10 in 1994. American singer Mariah Carey, East 17 and British boy-band Take That shared the record for the most top ten singles in 1994 with four hit singles each. Carey's cover of the Badfinger song "Without You" was her biggest hit of the year; it reached number-one in February and spent four weeks in that position, and eight weeks in the top 10 in total. Her other top ten singles were "All I Want for Christmas Is You" (number 2) in December; "Endless Love" (3) with Luther Vandross in September; and "Anytime You Need a Friend" (8) in June. Three of Take That's four top ten singles reached number-one in the UK: "Babe" in December 1993, "Everything Changes" in April and "Sure" in October. "Love Ain't Here Anymore" was their other top 10 entry, which reached number 3 in July. East 17 also had a number-one single in 1994, "Stay Another Day", which stayed there for 5 of its 8 weeks in the top ten. Their other top ten singles were "Around the World" and "It's Alright (both number 3) and "Steam" (number 7). Bon Jovi, Oasis and Eternal had three singles in the top ten in 1994.

question:
Question: Is Orel Hershier younger than the Mets player he replaced during the 1999 National League Championship Series? Passage:The game began shortly after 4 p.m. with Greg Maddux pitching for Atlanta and Masato Yoshii starting for the Mets. The Mets took an early 20 lead in the bottom of the first inning as John Olerud hit his second home run in as many days with Rickey Henderson on first. The lead lasted into the fourth inning, when Atlanta struck back with consecutive doubles by Bret Boone and Chipper Jones, eventually knotting the score at 22 when Brian Jordan singled home Jones. Mets Manager Bobby Valentine was immediately prompted to remove Yoshii from the game in favor of Orel Hershiser, which began a run on pitching changes that resulted in the Mets emptying their bullpen by game's end, relying on starter Kenny Rogers and rookie Octavio Dotel for key innings, and might have gone to Game4's starter Rick Reed had the game progressed past the fifteenth inning. In all, the Mets used a postseason record nine pitchers in this game.
