It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The term "marina barrage" is likely referring to a man-made barrage that regulates the flow of water in Singapore's Marina Channel, which is not related to public housing or maintenance issues. 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 the post is not related to the requested topic.
