premise: A man in a black shirt crouches next to a dirty unfinished concrete edge while several shovels and other tools lean against a tree nearby. hypothesis: The man's black shirt is covered in the dirt from gardening.
neutral: Just because a man crouches next to a dirty unfinished concrete edge, it doesn't mean the man's shirt is covered in dirt. Just because shovels lean against a tree, it doesn't mean someone is gardening.
