Documentaries are mostly TV, tapes/CDs/videos and sometimes books, but very rarely songs or videogames, and Historical is about real events if it's a biography, or if it's historical
fiction can fit into other genres such as the above.
The genres on the list are ones that are universal, in the sense that every sort of fiction can fit into it.
(Western is an exception that wasn't put in; although any sort of fiction can take place in the Wild West it can also be an action Western, adventure, drama etc. or in other words crosses over to other genres easily.)
Horror and Romance. They are both two pointless genres that are just progressively going down the stuffter.
Remember what I said? You may cross out only one of all the choices. But you've presented an interesting situation - you can cross out one of them, but you will suffer from the other. Which of the two is the worst, then?
