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 additional context or information that would suggest otherwise. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because the post does not fit into any of the other categories. The "explanation" field provides a brief explanation for why the post does not relate to the topic.
