It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house. The term "river safari singapore" does not suggest any maintenance issues or feedback related to 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.
