It seems that the Twitter post "oos challenger" does not relate to a maintenance report feedback to public flat house. It is not clear what this term "oos challenger" refers to, and it does not appear to be a common term in the context of public housing or maintenance reports. Therefore, I have marked the relatedness as "False" and the type as "none" in the JSON output.
