It seems that the provided Twitter post does not mention any information related to a maintenance report feedback for a public flat house. The post mentions "expo mrt interchange cg1 dt35 singapore", which appears to be a location or a transportation-related information, but it does not contain any keywords related to maintenance report or public flat house. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it does not fit any of the categories provided. The "explanation" field is left empty since there is no further information to provide.
