What can I do with a Comparative Literature major and a Biology minor?

I'm trying to figure out my course schedule and my options are double majoring in Comparative Literature and Biology, majoring in Comp.Lit. and minoring in Biology, or majoring in Com.Lit. and getting a BA in Science in a year-long program after graduating. I have a full scholarship, so I'm trying to make the most of it, but I don't know which I should do. Which one would guarantee me a reasonably well paying job with the option to become an editor at a later date?
