Explanation:

To determine which data supports a drought warning, we analyze each option:

• Air quality tests (toxins) relate to pollution, not drought.
• New camping/recreational sites affect ecosystems but not drought directly.
• Forest clearing (logging) impacts deforestation, not drought indicators.
• Reservoirs and lake levels dropping significantly directly indicate reduced water availability, a key drought sign.

Answer:

Reservoirs and lake levels continue to drop significantly.
