Read the following passage carefully and answer the question based on it: 'Art historians often cite Michelangelo's unfinished 'Slaves' series as a perfect metaphor for the creative process. In these sculptures, the human figure appears to be struggling to break free from the raw stone. For the sculptor, the vision is not realized in a sudden flash of brilliance. Rather, the form is 'released' from the marble bit by bit. One might see a knee emerging here, a tensed shoulder there, or the faint outline of a head appearing through the granite. This illustrates that any profound work of art is a product of incremental steps; it is a gradual assembly of fragments rather than a sudden, complete arrival of the finished object.' How does the passage describe the realization of a creative work?
