Bella always tried to fight her feelings about Jacob, she fooled herself into thinking that it was nothing more then a friendship with him. After everything she went through after not having Edward throughout New Moon she relized that she really did love Jacob. The third book Eclipise is really all about Bella figuring which life is better for her, the life with Jacob her best friend, or the life with Edward he first love.
So Bella's feelings never changed from not loving Jacob..those feeling only grew stronger. In the end of course she knew that although she loves Jacob, Edward is the one she needs to be with.
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.
