It seems that the tweet "cave singapore" does not relate to a maintenance report feedback to public flat house. It is not clear what the tweet is referring to, and it does not contain any keywords or phrases that suggest it is about 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 possible to determine the type of feedback being provided. The "explanation" field is left blank because there is no explanation for why the tweet is not related to the given topic.
