This is unsupported because the authors leave out information regarding the noticeable differences between Michelangelo’s work and additions made by later artists.

This is strongly supported because stripping away everything but the original fresco may result in some of Michelangelo’s own intended additions also being removed.

This is unsupported because the stimulus avoids offering information on the components of a work’s design or the impact that additional details have on design.

This is unsupported because the painters who made additions may themselves have been important artists. The stimulus does not specify who made additions to the Sistine Chapel paintings.

This is unsupported because we don’t know how often Michelangelo made additions to his entire body of works or whether or not those additions reflect dissatisfaction with the original work.
