The correct answers are Symbols have a concrete, physical existence. Symbols carry alternate, associated meanings.
Indeed, the definition of a symbol is a visual sign or an image that represent an idea, notion, person, place or concept.
Letters and numbers are symbols and images, sculptures and other forms of art are also symbols and thus have a concrete physical existence. They carry alternate associated meanings. The American Bald Eagle is normally a carrion eating bird but it has become the symbol of the United States.
