Scott Joplin is recognized as an American composer and pianist, particularly in which domain, as noted in the material?

• A. Painter
• B. Politician
• C. Composer and Pianist
• D. Poet

Answer: (C)

The main idea is identifying the field in which Scott Joplin is recognized: music. He is described as a composer and pianist, known for creating and performing ragtime piano music, which makes music his primary domain. This is why the correct choice highlights his role as a composer and pianist. The other domains—painting, politics, and poetry—do not align with how he is framed in the material, which centers on his contributions to music and the ragtime tradition.
