    A class for checking the validity of factual statements.
    
    This implementation uses a simple keyword matching approach to simulate fact-checking capabilities,

This Python script introduces the `FactChecker` class which implements a basic keyword matching mechanism to check the validity of factual statements. The example usage demonstrates how to use this class with predefined keywords and sample statements.
