A Versus B Posts: Many To Come

For a long time now, I have wondered when one should refer to A versus B about many different things. I have decided to help out humanity by not only answering each question which, like how Churchill refered to Russia, can be seen as a "riddle wrapped in a mystery inside an enigma" but by posting the answer to my site as well. In the immortal words of Bill Cosby, I hope you have some fun and learn a bit before you're done.
