It seems that the Twitter post "arc 380 singapore" does not relate to a maintenance report feedback to public flat house in Singapore. The term "arc 380" is likely a reference to a specific location or building in Singapore, but it does not contain any keywords related to maintenance or public housing. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because 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.
