How many Boston cities are in USA?

Excuse me, but I must ask, does the question "How many Boston cities are in the USA?" truly reflect an accurate inquiry? Boston, as a matter of fact, is a singular city located in the state of Massachusetts within the United States. Perhaps you meant to inquire about the number of major cities in the USA, or perhaps you were referring to a different context altogether. Could you please clarify your question, as the notion of "Boston cities" within the USA seems to be a misconception?
