An Response area is a trade good produced outside of a civilization and bought or traded for by that civilization. An Response area is a trade good that is produced in a civilization but sold to places outside of that civilization.

Thank you for providing those definitions. It seems there may be a slight misunderstanding in the second statement. Let me clarify:

A "response area" generally refers to a geographical region or territory that a civilization can control or influence. It is typically associated with the trade and resources that originate from within that area. Therefore, it might not accurately represent a trade good.

Instead, a trade good produced within a civilization and sold to places outside of that civilization can be referred to as an "export." Exports are products or services that are produced domestically but traded internationally or sold to other civilizations.

On the other hand, a trade good produced outside of a civilization and purchased or traded for by that civilization can be termed as an "import." Imports are goods or services that are acquired from other civilizations or regions and brought into a civilization for consumption or trade.

To summarize:
- An export is a product or service produced within a civilization and sold to other places outside of that civilization.
- An import is a trade good acquired from outside a civilization and purchased or traded for by that civilization.

I hope this explanation clarifies the definitions for you. If you have any more questions, feel free to ask!
