-We know this woman is a witch because she looks like one.
-We know this woman is a witch because she dresses like one.
-We know this woman is a witch because she has a wart.
-We know this woman is a witch because she turned someone into a newt.
-One burns witches.
-One burns wood.
-Witches burn because they are made out of wood.
-Bridges are made of wood.
-However, bridges are multiply realizable. They can be built from stone. [Implied] Building a bridge out of the woman will not determine that she is made of wood.
