Playing it dumb.

I know dear reader this is seems to be a strange headline but as i write this post i hope you will understand a bit more.I have noticed when going to tests for benefits or get help if you show any insight or knowledge it is frowned upon.So you can take 2 options -1 lie which is wrong and you will get caught out at some point,2-play dumb just keep replies to yes ,no and show no insight is this ok no not really but its the only thing that works .
