What does specify one suburb only mean?

The phrase "specify one suburb only" means that you can only include one suburb in your response or action. Suburb refers to a residential area just outside a city. For example, if you have a list of properties in multiple suburbs and are asked to specify one of them only, you must choose just one suburb from the given list rather than providing all locations or selecting several suburbs. This instruction ensures that you focus on a single specific area and provide detailed information or perform tasks limited to that suburb only.
