race and checkmarks

Often for research purposes, standardized tests and surveys will often put a box where one has to fill in their race. The only options they give are usually african american, caucasian, pacific islander, and hispanic. Although for me personally, it isn't hard to fill in, there are people out there who don't really fall into any of those catergories. In class we looked at people who were from Australia but would be called "black" in America, but on that question they can't really fit into the african american category because they aren't from Africa. I think that like the author of "Mixed Blood" said Race is a myth. Race is a bunch of simple words like black and white that society created definitions for. Back from the orgins of slavery, it is apparent that a majority of "white" people feel superior to blacks or have a prefrence to white people over blacks although they probably don't consider themselves racist. So what race does exsist? the human race, and everyone is apart of it no matter what their physical features are.
