Final answer:
Andy Warhol has turned the bulls in his Cow Wallpaper artwork into symbols of humor and satire.
Step-by-step explanation:
Andy Warhol has turned his bulls into symbols of humor and satire in his Cow Wallpaper artwork. The repetition of the bull motif in the wallpaper is a humorous play on the repetitious patterning of traditional wallpaper. By transforming the bulls into a satirical element, Warhol challenges the traditional symbolism and meaning associated with bulls, such as their representation of strength and authority or fertility and power.
