To determine the correct tone expressed in paragraphs 23 and 24 of “The Green Belt Movement,” I would need to analyze the content of those specific paragraphs. However, I don’t have access to that text directly.
Generally speaking, if the context revolves around environmental efforts and community engagement, options like "appreciation" or "curiosity" might be more fitting. If the text discusses negative outcomes or challenges faced by the movement, "pessimism" could apply. "Arrogance" would typically imply a dismissive or superior attitude, which might not be common in discussions of grassroots movements focused on environmental and social issues.
If you can provide more context or a summary of those paragraphs, I could help you make a more informed decision. Otherwise, based on common themes, "appreciation" is often a good guess in similar contexts.
