Final answer:
The artist may have broken the rules of proportion in the caricature drawing to represent a realistic drawing or emphasize specific elements.
Step-by-step explanation:
The artist may have broken the rules of proportion in the caricature drawing for several reasons. One possible reason is to represent a realistic drawing. By exaggerating certain features, the artist can capture the essence of the subject in a more recognizable way. Another reason could be to emphasize specific elements in the drawing. For example, if the artist wants to draw attention to a small balloon, breaking the rules of proportion can make it stand out more.
