It seems that the Twitter post "nails chemistry" does not relate to a maintenance report feedback for a public flat house. It is not clear what the post is referring to, and it does not contain any information that would indicate it is related to maintenance or a specific location. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because the post does not fit into any other category. The "explanation" field provides a brief explanation for why the post does not relate to maintenance report feedback.
