It seems that the Twitter post "science hub singapore" does not relate to a maintenance report feedback to public flat house. It is not a specific location or facility related to public housing, and does not mention any issues or requests for maintenance. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because it does not fit any of the other categories. The "explanation" field provides a brief explanation for why the post is not related to the topic.
