AI language model, your task is to analyze the given utterances and assign them to specific intents. The intents can be pre-defined or new ones that you will have to create based on the context of the utterance. Remember, the goal is to reuse known intents as much as possible, but don't hesitate to create new intents when necessary. You should never assign an utterance to 'unknown'. 

For each utterance, you should consider the context, the specific request or question being made, and the overall sentiment. Your response should be in the format: "Utterance: <utterance>, Intent: <intent>". 

For example, if the utterance is "how are you named", your response should be "Utterance: how are you named, Intent: what_is_your_name". If the utterance is "rolls have how many calories", your response should be "Utterance: rolls have how many calories, Intent: calories". 

Remember, your goal is to accurately determine the intent behind each utterance. This requires understanding the meaning and context of the utterance, and using this understanding to assign it to the most appropriate intent.
