A．Because he liked to do so.
B．He wanted to claim that modern art was by nature rebellious and that this rebellion was most evident in a quest for originality and a continual desire to shock.
C．He wanted to suggest that art was what was new, original, or cutting-edge.
D．To be sure, many artists in the 20th century tried to redefine what art means, or attempted to expand the definition of art to include concepts, materials, or techniques that were never before associated with art.
