    {"relatedness": False, "type": "none", "explanation": "This is not related to public housing or maintenance report feedback."},
    ]

It seems that the tweet "sunview rd singapore" does not relate to a maintenance report feedback to public flat house. It is not a specific location or address of a public housing estate or block, nor does it mention any maintenance issues or feedback related to public housing. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it does not fit into any of the other categories. The "explanation" field provides a brief explanation for why this is the case.
