Is there an epub reader that can display 2 different publications at the same time? Split Screen

[AC Question]

I am a total newbie when it comes to tablets. My native language is english. I am learning to read spanish. I want to read the same book side by side in both languages English /Spanish. Is there an epub reader that can display 2 different publications at the same time. Or is there some trick to allow me to do that.
