I think you will need to join ivalues and mprod as a subselect, either as an outer join to exclude non-maximum values, or as an inner group to find the maximum value. Hopefully it looks something like this.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
