                                    - The model is prompted with a question-answer format. The input consists of a question, and the model generates a response based on the understanding of the question and its knowledge.

                                    - Involves providing the model with explicit instructions on how to generate a response. Instead of relying solely on context or previous knowledge, the instructions guide the model in generating content that aligns with specific criteria.
                                - Strategy 3 - Structured Prompting
                                    - Involves presenting information to the model in a structured format, often with defined sections or categories. The model then generates responses following the given structure.
