Not sure I need to offer a source, other than my own common sense. A guided tour is where someone or a team of people from an organised tour company or independent tour guide, takes a group or individual around, explaining details of interest as the tour goes along.
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.
