Translation:There is not much dancing in the prison.
I don't know about this being a good sentence... few prison sentences are ever good...
It just means their vetting process is working. Nothing about your sentence is correct.
mmm... can't you say something like: "Is not being runned much in this olympics"
1) No subject in your sentence. 2) 'run' being used in passive voice for an intransitive sense. 3) Olympics is plural, hence 'these' instead of 'this'. 4) It's 'Olympics', not 'olympics'.
Thanks for the correction!
So the only error I did in the first sentence was not to write the subject: "it".
