premise: A man in a red shirt with blue jeans on is standing under a tent and standing in front of a table with vegetables on it. hypothesis: A man in a green shirt with blue jeans on is standing under an umbrella and standing in front of a table with rabbits on it.
contradiction: If the shirt is green, it isn't red, he wouldn't have an umbrella under a tent, and there wouldn't be both vegetables and rabbits on the table.
