Re: Need help - Abstract editing
Welcome to Using English.
There are some tweaks to make to the first part, but once you get to "As an alternative," I am unable to understand your meaning at all. It leaves me completely mystified.
In the first part, delete "Furthermore." Change "Nevertheless" to "However." What are the limitations and exceptions in? Copyright law? Whose literature? The noun "determining" takes the singular verb "remains." But then... I have no clue.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
