If I were you I would first look at some information regafding the AAP. Look for how many hours daily people spend watching tv. Next look at the demographic. is it mostly woman who watch this channel or men?
children or adults?
Finally, I would decide on whether or not having longer screen time would be a benefit. It looks like they want you to write a persuasive essay, and essay that explains why the reader should be motivated to see you point of view.
Mostly get the reader to agree with you on whether/whether not screen time should be raised.
Oh, and research research, research. Nothing says a good paper like background knowledge.
I hooe this helps a bit.
