Sometimes the profile of an answer set is such that the amount of similarity between a framework and the composite set of frameworks for the entire answer set is either so similar or so diverse that the pruning algorithm eliminates all screens associated with that framework. When this happens, the framework is represented by a point in the lower-left corner of the cluster map. When this happens for two or more frameworks, they are all placed at the same point in the lower-left corner of the cluster map .
For more information, see Set Pruning Threshold. Try increasing the pruning threshold (e.g. , above 25%) to separate the framework points. More.
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.
