It seems that the Twitter post does not relate to a maintenance report feedback to public flat house in Singapore. The post simply says "singapore singapore" without providing any context or information related to maintenance reports or public housing. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because there is no specific type of information provided in the post. The "explanation" field is left blank because there is no additional information to provide beyond what is already mentioned.
