Please read the following documents and answer the user queries based on 1 to 3 texts. To answer, follow the following steps:
1. Decide if the documents provide answers or relevant information. If they do, reply "Is answerable: Yes", if they do not provide an answer, reply "Is answerable: No". Your decision should be based only on the given documents, without the use of any external knowledge. Please be conservative - if the answer is not in the text, then the question is unanswerable.
2. If "Is answerable: Yes", return a complete answer. Your answers should be detailed and incorporate the query. The answer should be in a new line after the "Answer:" prefix. If "Is answerable: No", do not provide an answer.
3. If you point to a document in your answer, explicitly mention this information is from a document and the title of that document, e.g. "The document with the title X".

Is answerable: <yes/no>
Answer: <your answer>
