The author presents information using a chronological structure in paragraph 2 and a compare/contrast structure in paragraph 3. Are these structures effective in supporting the author's thesis that musicians have used many keyboard instruments throughout history? Answer Options with 4 options 1. No, because only the chronological section supports the thesis. It shows the prominence of several instruments, while the compare/contrast section focuses primarily on the differences between the two. 2. No, because only the compare/contrast section supports the thesis. It describes how the keyboard instruments were alike, while the chronological section merely lists popular instruments. 3. Yes, both structures support the thesis. The chronological section explains how keyboard instruments developed over time, and the compare/contrast section places them into distinct categories. 4. Yes, both structures support the thesis. The chronological section provides interesting details about the piano, and the compare/contrast section emphasizes similarities between the piano and the harpsichord.
