I am using this question for a hook in my essay. Unfortunately, this question failsl to grab the reader so I am looking for a more interesting way to state this question. HELP!!
I agree with post four that it completely depends on what type of paper you are writing. If this is a class essay topic, I'm sure your teacher has seen a million papers beginning with a question almost identical to yours. In order for a hook to be effective, it has to be different. You really want your readers to keep looking for where that statement came from (although you don't want to make it so off the wall that it doesn't connect to the rest of the paragraph). Your hook should feed into your main point. Be as specific as possible without giving away the ending.
Depending on what type of essay you are writing, you should think ahead to what point you are ultimately trying to make. If you are writing about this theme as it relates to a work of fiction, then determine what the author's viewpoint is in that work. Use that to provide more focus and specificity to the topic.
If you are writing a personal argument paper, then one possibility is open your paper and talking about brief aspects of your own personality that you think are shaped by your upbringing, and other aspects that you are more sure are related to your environment (school, neighborhood, church, country, etc). Then write a thesis statement that establishes whatever argument that you are going to go on to prove.
What about finding real world examples of sibling who are similar and then other examples of siblings who have turned out much differently from one another. You could present the similar ones and say that it makes sense that these two brothers would both be in the NBA or whatever. Then you could contrast it with really dissimilar siblings and then say "what's going on here?" That might be more interesting than a plain statement of the nature v. nurture question.
If I were you, I would try something far more specific and perhaps off the wall. If you think about strange examples from your environment, perhaps you could use something from your childhood. I think of maybe something along the lines of "am I a product of growing up with a river in the back yard and two brothers and a string of pet hamsters and gerbils and rabbits or going to school with a whole bunch of future criminals and delinquents and a few kids on their way to Harvard?"
I am just thinking that you could just something more specific like that instead of the nature vs. nurture phrase that everyone has heard too many times.
