Well what do your "critical thinking" skills tell you the answer is? Once you answer that then I suggest you click on the links to the three articles I posted on this thread and try to deduce for yourself the answer to your newly posed question and compare/contrast it with your "critical thinking" thought.
I assure you the factual answer to your question is in at least one of the articles. I won't do your homework for you. =)
