From your error message it looks like you do not have a recent version of the hoe gem installed. Try doing a gem install hoe --version '> 1.7.0 and see if it helps. It may be that when you installed the rspec and rspec-rails gems you did not get the dependencies as well and there may be other dependent gems missing.
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.
