Talcott Parson’s Structural-Functionalism’s OR Karl Marx’s Social Conflict Theory’s take on the current issue; Roe v. Wade. 
You should clearly articulate what the “problem” you are investigating is. 

You should clearly introduce, define, and apply the theory (or theories) you are using. This is your opportunity to demonstrate you comprehend and can apply the theory. 

The sources can be original texts from the theorist you are using or academic articles that expand upon the original theories. In either case, your sources must be academic. In other words, they must be books published by scholarly presses or articles published in scholarly journals. Your incorporation of ideas from these sources should be meaningful.
This paper should be well-written, with a clear organizational structure.
