    # Checking facts

    print(checker.check_fact("This is a false statement based on rule2"))  # Should return False

```

This example demonstrates the `FactChecker` class capable of verifying simple statements using predefined rules. The `check_fact` method evaluates the condition part of each rule and returns the result if the condition matches, otherwise, it defaults to `False`. The `add_rule` method allows adding new checks for facts based on conditions and their outcomes.
