Add 10 policy-maker and impact-focused questions for driving real-world change

POLICY & IMPACT QUESTIONS ADDED:
🚨 Emergency Response:
- 'Which cities need immediate emergency intervention with PM2.5 >100 μg/m³?'
- 'Which cities have PM2.5 levels in hazardous category (>250 μg/m³) requiring urgent action?'
- 'Identify seasonal emergency periods when public health advisories should be issued'

📊 Resource Allocation & Planning:
- 'Rank states by average air quality to prioritize national-level resource allocation'
- 'Calculate population-weighted pollution exposure to identify areas affecting most people'
- 'Which months require targeted interventions based on highest pollution spikes?'

🏭 Policy Effectiveness & Strategy:
- 'Compare pollution levels between industrial vs non-industrial cities for policy focus'
- 'Show cities with worsening pollution trends that need immediate policy intervention'

✅ Success Stories & Replication:
- 'Identify cities showing consistent pollution improvement for policy replication'
- 'Compare pollution reduction success: which cities improved most and how?'

INTERFACE IMPROVEMENTS:
- Increase visible questions from 15 to 20 to show policy-focused questions
- Questions now serve both researchers AND policy makers for maximum impact

These questions help policy makers make data-driven decisions for public health protection, resource allocation, and regulatory interventions.
