Option 1 -> The writer explicitly mentions "my imagination" as one of the qualities he values most that came from his teaching.
Option 2 -> The writer clearly states "my curiosity" as one of the cherished qualities developed through his education.
Option 3 -> The writer references "my love of acting" and "my passion for writing" as valued qualities from his schooling.
Option 4 -> There is no mention of temperament, discipline, or behavioral correction anywhere in the passage.
Hence, Option 4: disciplining his temperament -> The writer only discusses intellectual and creative qualities (imagination, acting, writing, learning, curiosity) that his teachers nurtured, but never mentions anything about disciplining behavior or temperament -> correct
