I want to write a causal argument on how kids get hooked on unhealthy/processed foods (at home-- fast foods and at school-- vending machine and cafeteria hot lunches). I'm not quite sure what exactly to write about throughout a causal argument paper on this claim. What details I should provide? What should and shouldn't I talk about?
