First of all, let me advise you that one does not "solve" a survey. The word "solve" usually means to effectively deal with a problem or mystery. As such one can give a "feedback" to a survey.
Secondly, I recall a similar survey was conducted several weeks back. I had sent my feedback and as such I am not doing it again this time. Possibly, you did not receive many feedback the last time when you had posted this at QL.
