# Example usage
if __name__ == "__main__":
    reasoning_engine = ReasoningEngine()
    
    # Adding some facts to the knowledge base
    reasoning_engine.add_fact("All dogs are mammals.")
    reasoning_engine.add_fact("Dogs have four legs.")
    reasoning_engine.add_fact("Some mammals can fly.")

    # Querying the engine with a question
    answers = reasoning_engine.query("Can all mammals fly?")
    
    print(answers)
```

This code defines a simple `ReasoningEngine` that uses a basic knowledge base to handle queries. The example usage demonstrates adding some facts and querying whether all mammals can fly, which should return "No information available." since the knowledge base lacks the specific fact about flight in mammals.
