    # GAIA Agent - Focused Version
    
    **Target: 30%+ Score**
    
    This agent focuses on questions that can be reliably answered with search:
    - Text reversal questions (guaranteed points)
    - Historical facts (Mercedes Sosa, Olympics, etc.)
    - Wikipedia-specific queries
    - Botanical classification (logic-based)
    - Mathematical table analysis
    
    **Key Questions Targeted:**
    1. Reversed text → "right" 
    2. Mercedes Sosa albums 2000-2009
    3. Botanical vegetables classification
    4. Commutative table counter-examples
    5. 1928 Olympics least athletes
    6. And more searchable factual questions...
