premise: The Outsiders are a professional wrestling tag team consisting of Kevin Nash and Scott Hall, best known for their first appearances in World Championship Wrestling (WCW) in 1996. They later teamed also in the World Wrestling Federation (WWF), Total Nonstop Action Wrestling (TNA), and Pro Wrestling ZERO1-MAX.
hypothesis: They competed in the WCW in 1990 + 6
reason: 1990 + 6 is 1996, the year they competed in the WCW. I think the model struggles to interpret addition to years.
