    A simple reasoning engine capable of solving limited reasoning problems.
    
    This class provides a basic framework for performing logical inferences and deductions based on given premises.

    Methods:
        infer(premises: List[Tuple[str, str]]) -> str:
            Infers the conclusion from the provided premises using a simple rule-based system.
