Q: The 2000 World Series was the 96th edition of Major League Baseball (MLB)'s championship series, and the conclusion of the 2000 Major League Baseball season. A best-of-seven playoff, it featured a crosstown matchup between the two-time defending World Series champions and American League (AL) champion New York Yankees and the National League (NL) champion New York Mets. The Yankees defeated the Mets four games to one to win their third consecutive championship and 26th overall. It marks, to date, the last World Series with a repeat champion. It was the first postseason Subway Series since 1956. The Yankees were in the World Series for the third consecutive season and fourth in the past five years, and 37th overall. This made it the most of any team in MLB. The Mets qualified to play in the World Series for the fourth time in franchise history, making this the most of any expansion franchise in MLB and its first since winning the 1986 World Series. This is the most recent World Series in which both participating teams had made the postseason the previous year.
Can we conclude that have the yankees and mets played in the world series?
A: yes

Q: Some notable performances in the Derby include Bobby Abreu in 2005, who won the Derby with a then-record 41 homers, including a then-record 24 in the first round. The first-round record was broken in 2008 by Josh Hamilton, who hit 28 home runs. Though Hamilton's performance was notable for the length of his home runs, he ultimately lost to Justin Morneau in a brief final round. The overall record was broken in 2016 by Giancarlo Stanton, who finished with a total of 61 home runs, defeating Todd Frazier in the final round. Only two participants, Yoenis Cespedes and Giancarlo Stanton, have won the Home Run Derby without being selected to the All-Star game itself.
Can we conclude that do you have to be an all-star to be in the home run derby?
A: no

Q: Safeties are the least common method of scoring in American football but are not rare occurrences -- since 1932, a safety has occurred once every 14.31 games in the National Football League (NFL), or about once a week under current scheduling rules. On October 21, 1973, Fred Dryer, playing for the Los Angeles Rams against the Green Bay Packers, became the only player in NFL History to score two safeties in a single game. A much rarer occurrence is the one-point safety, which can be scored by the offense on an extra point or two-point conversion attempt; those have occurred at least twice in NCAA Division I football since 1996, most recently at the 2013 Fiesta Bowl. No conversion safeties have occurred since at least 1940 in the NFL. A conversion safety by the defense is also possible, though highly unlikely; although this has never occurred, it is the only possible way a team could finish with a single point in an American football game.
Can we conclude that is it possible to have a score of 1 in football?
A: yes
