premise: A crowd of interested people surrounds a man swinging a sledgehammer.
hypothesis: A man shows a group of people how to use a sledgehammer.

explanation_2: Just because the people are watching the man swing the sledgehammer does not necessarily mean he is showing them how to do it.
explanation_3: To use a sledgehammer does not always represent a tutorial
