Which of the following is not a purpose of art?

Art has been used for thousands and thousands of years, with evidence of some forms of art done by cavemen in the form of drawings on walls. When Neanderthals were drawing on the walls of their caves, it was used as a form of documentation, showing the way they hunted, harvested, and their everyday life.

Art is also used as a form of expressing one’s feelings and views of hardships, life, and tragic events, attempting to allow others to form feelings and to help people see the world in a different light or a new perspective. The development of art has advanced in leaps and bounds, but will never become extinct.
