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 "subway Singapore" without providing any further context or information. Therefore, I have marked the "relatedness" field as "False" and the "type" field as "none" in the JSON output.
