Credit is how much you charge to credit ( duh haha) which you'll have to pay back later but don't have money for now. Debit is how much money you have in the bank like pay checks stuff like that And overall balance I'm guessing would be from the debit but it could also be how much you have left after the credit is taken from the debit account Sorry if thats confusing hahah.
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.
