-    - 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...
