That's not how to implement Adsense in Hubpages. See the 'how-to' information on Hubpages for that.
No you do not put the HTML code into a hub. Go to your account page and under earnings click configure on google adsense and then you can insert the code there. Welcome to HubPages.
Sorry I didn't realize that missOlive had already answered your questions.
Click 'Configure' Google Adsense (about midway down).
This will get your Google account connected to your HubPages account.
Actually, you CAN put HTML into your hub's text capsules (click the HTML icon at the top left corner of the capsule), but that's not the way to configure Adsense. See missolive's answer.
Your question has already been answered by miss olive. Nothing more to add.
No you can't and you don't need it to be done.
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.
