IF there was one Questions you could ask "GOD" what would that question be?

Face it everyone has many many questions they want answered and many are very hard and yet some seem impossible to answer.

So If you could find the answer to one question, like why did god take a mothers son or daughter away from her etc... Or Some other answer that would be beyond the realm of human's to answer.
