At the Library. I hope this helps.
I would say anything debatable, if we use a real world topic like the death penalty. you could argue for it to be mandatory or to abolish it. If you want a lighter subject like pineapple on pizza (might not want to use this one if your doing a serious assignment) you could argue it doesn't belong and put the effects. I would find a controversial topic and see if you like it.
Hope this could help!
