    ]

It seems that the Twitter post "serfing singapore sg" does not relate to a maintenance report feedback to a public flat house. The post does not mention any specific issues or facilities related to public housing, and does not appear to be a complaint or feedback of any kind. 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 is left blank since there is no additional information to provide.
