It seems that the tweet "sin singapore" does not relate to a maintenance report feedback to public flat house in Singapore. The tweet does not mention any specific issues or facilities related to public housing, and does not appear to be a complaint or feedback of any kind. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it is not related to any specific category. The "explanation" field provides a brief explanation for why the tweet does not relate to the given topic.
