It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The post simply mentions "mbs underground mrt singapore" which does not provide any context or information related to maintenance issues or public housing. 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 this is the case.
