It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The term "national dental centre singapore" does not contain any keywords related to maintenance report feedback or 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.
