You may have to build up some content before you apply. I waited until I have 10 hubs that were rated above 60. Then I applied and it went well for me.
Good luck.
I know your article has to be a certain length.. try at least 1 page. Also you need a gmail account, did you apply with your gmail address?
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.
