1 sounds to be the easiest. Just look at the three theories and decide which one best fits your life. Which one do you aree with the most. Personally i would go with Marx's conflict theory, which is basically the struggle of the have's (those with money and power...politicians, business owners, etc), vs. the have not's (everyone else) assignment square. Marx says that the haves create laws and policies to keep the have notes from gaining any power. That is just a rough, very brief overview. Hope that helps a little.
