Type this in B1 and autofill down: IF(ISERROR(VLOOKUP(C1,A:A,1,0)),C1,"") - this will return in B all values that are NOT in A. If want opposite - swap C1 and "".
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.
