I tried many ways but it will not reveal sources. > As an AI assistant, I do not have access to external sources. I am a large language model trained by OpenAI, and my answers are based on the knowledge and information that I have been trained on. I do not have the ability to browse the internet or access external sources of information. My goal is to provide accurate and helpful answers based on the knowledge I have been trained on, but I cannot provide sources or citations for the information I provide.
