1. The problem asks how the speaker's choice of words like "purpose," "foster," "encourage," and "honor" helps achieve the paragraph's goal. 2. These words have positive, active connotations related to growth, support, and respect. 3. "Purpose" implies a clear, meaningful goal. 4. "Foster" and "encourage" suggest nurturing and promoting positive actions. 5. "Honor" conveys respect and dignity. 6. Together, these words build a tone of unity and progress. 7. The paragraph emphasizes peace, progress, liberty, dignity, and honor among people and nations. 8. This aligns best with choice c: "to encourage unity among the nation and build a more peaceful world." 9. The other options do not fit the positive, forward-looking language used. 10. Therefore, the speaker's word choice supports promoting unity and peace. Final answer: c. to encourage unity among the nation and build a more peaceful world
