One way to get a bot to answer a question on another question is to program specific responses into the bot's algorithm. You can create a scenario where if the bot is asked a question on a certain topic, it will respond with a relevant answer. Alternatively, you can use a chatbot platform that allows you to set up rules and conditions for how the bot should respond to different types of questions. This way, you can customize the bot's behavior to answer questions based on the context of the conversation.
