A man in a red shirt is standing next to a woman in a blue dress. They are both holding hands and smiling at each other. A person says 'I'm going to the store' but doesn't actually go. Is the statement 'I know' true? If I'm being completely honest, I'm not sure if I'll be able to attend the party because I have a prior commitment. Can we conclude that I'm not sure if I'll attend the party?
yes
no
it is not possible to tell
