Read this: The term Appalachian refers to several different regions associated with the mountain range. Most broadly, it refers to the entire mountain range with its surrounding hills and the dissected plateau region. The term is often used more restrictively to refer to regions in the central and southern Appalachian Mountains, usually including areas in the states of Kentucky, Tennessee, Virginia, Maryland, West Virginia, and North Carolina, as well as sometimes extending as far south as northern Alabama, Georgia and western South Carolina, and as far north as Pennsylvania, southern Ohio and parts of southern upstate New York.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): Which southern states are not referred to in the more restrictive understanding of Appalachian?
