It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The term "terminal 4 Singapore" could refer to various things, but it does not seem to be a specific reference to a maintenance issue or public housing in Singapore. 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 this is the case.
