One question can be replaced by any number of synonyms to convey the same meaning or intent. Some examples include inquiry, query, interrogatory, or problem. Depending on the context, variations such as issue, concern, or matter may also be suitable alternatives. Additionally, if multiple questions are being asked at once, phrases such as "a set of questions" or "a series of inquiries" can be used instead of "one question." It's important to choose the right synonym based on the tone and purpose of the communication. By utilizing diverse language, one can effectively communicate their message in a clear and engaging way.
