    BusinessDomain Class

    Design:
    This class extends the KnowledgeDomain class following the Open/Closed Principle (OCP) 
    and provides a specific implementation for generating responses to business-related questions. 
    Its single responsibility, as per the Single Responsibility Principle (SRP), is to generate 
    business-related responses.

    Intended Implementation:
    The generate_response method should be able to generate accurate and helpful responses to 
    business-related questions. The logic for generating these responses could be rule-based, 
    or it could use a trained machine learning model.

class BusinessChain(DestinationChainStrategy):
    """
    BusinessChain Class

    Design:
    This class is a specific implementation of the ChainStrategy class.
    It follows the Open/Closed Principle (OCP) because it extends the ChainStrategy class 
    without modifying its behavior. It also adheres to the Dependency Inversion Principle (DIP) as it 
    depends on the abstraction (BusinessDomain) rather than a concrete class.

    Intended Implementation:
    The BusinessChain class serves as a wrapper around a BusinessDomain instance. It implements the run 
    method from the ChainStrategy class, which simply calls the generate_response method of the BusinessDomain.
    As such, when the run method is called with a question as input, the BusinessChain class will return a 
    response generated by the BusinessDomain. This response will be business-related, as the BusinessDomain is 
    designed to generate responses to business-related questions.
