For a project focused on biographies organized around places, a student recorded the following information: • Rooms of a Cartographer groups chapters by the studios, classrooms, and field camps where its subject worked. • Events from different years appear together when they occurred in the same place. • Stations of a Violinist groups chapters by the rehearsal halls, homes, and cities where its subject performed. • Events from different years appear together when they illuminate the meaning of one place. • Both biographies include timelines in an appendix rather than using chronology as the main organizing structure. To meet the writing goal, the student must highlight the shared structural choice made by the two biographers. Which choice does so most effectively?
