premise: Boomer is the official mascot of the Indiana Pacers, a professional basketball team that plays in the National Basketball Association (NBA). He appears at each of the Pacers' home games, at special events for the NBA, as well as at other community & sporting events in central Indiana.
hypothesis: Boomer can be seen at events outside of Indiana Pacer games. 
reason: The data states "boomer goes also to special events for the NBA" so that would be things outside of Pacer games.  It was probably difficult for the system because it can't figure out that special events are different from games.
