premise: One man dressed in black is stretching his leg up in the air, behind him is a massive cruise ship in the water. hypothesis: A man goes through his tai chi routine in the park in front of the pier where a cruise ship prepares for boarding.
neutral: A person can be dressed in black and stretching their leg for other reasons then tai chi and it does not mean they are in a park either. Also a cruise ship being in the water does not mean they are at a pier or that the cruise ship is currently boarding.
