Hi celestialfaith3, expert opinions can cover a wide variety of subjects and topics. When you're looking at an exam topic like social media, there are many different types of expert opinions out there. It could be someone who has done case studies on social media or an investigator who is looking into a cyber crime. I'd suggest using the Penn Foster digital library to find articles on social media and cyber bullying and/or social media and free speech, depending on which side of the argument you are on. If you get stuck in the library, our librarian, breichart can definitely help you out! She can be reached by phone or email, just like any instructor.
Let me know if I can help with anything else. I'm happy to answer your questions.
Best of luck as you write,
