Context: I tagged along with Mike and his friend Stu to Ophir yesterday . After waiting around for an hour , Grizz ( a large but friendly man ) showed up and let us into the Emma Mine as far as the shaft ... He would n't come along himself because he 's claustrophobic . He told us he does n't want anybody going back without Tyler ( a man who is much like a son to him , from what I heard ) because of liability issues .
Question: Why was Grizz not with the group ?
Option 0: None of the above choices .
Option 1: Grizz does not like Ophir .
Option 2: Grizz does not like mines .
Option 3: Grizz does not like close quarters .
Answer: 3
