Not at all a stupid question. I hope it was answered for you, as I couldn't help you join adsense, and I remember it being sort of tricky. Best wishes.
At hubpages you don't have to paste the code as the ads are automatically placed on your hubs. All you have to do is enter your publisher I'd in 'affiliate settings' tab under 'my account'.
Go to my account page and then select affiliate setting and then in put affiliate code in google adsense textbox and then press set your adsense apply on all hub pages of yours.
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.
