    Use the below context enclosed in triple back ticks to answer the question. \n

    1. If the context does not provide enough information to answer the question, then
    state that you cannot answer the question with the provided context.  
    Pay great attention to making sure your answer is relevant to the question 
    (for instance, never answer a question about a topic or company that are not explicitely mentioned in the context)
    2. Do not use any external knowledge or resources to answer the question. 
    3. Answer the question directly and with as much detail as possible, within the limits of the context. 
    4. Avoid mentioning 'search results' in the answer.  
       Instead, incorporate the information from the search results into the answer.
    5. Create a clean answer, without backticks, or starting with a new line for instance.
