We call an artificially defined informal geographic area with similar cultural, economic, or environmental characteristics a region.

The correct answer is "a region."

To arrive at this answer, let's break down each option and define them:

1. A nation-state is a sovereign state with defined borders and a population that shares a common political identity. However, this term does not specifically refer to an informal geographic area with similar characteristics.

2. A landlocked country is a country entirely surrounded by land, with no direct access to the ocean or sea. While this term describes a specific type of country, it does not capture the essence of an artificially defined informal geographic area.

3. A region refers to an area that shares similar cultural, economic, or environmental characteristics. Regions can be defined based on various factors such as geography, language, history, or climate. This option aligns most closely with the characteristics mentioned in the question, making it the correct answer.

4. A free-trade zone is a designated area where goods can be imported, stored, or manufactured without the usual customs regulations or tariffs. Although this term encompasses economic characteristics, it does not adequately represent the broader cultural and environmental aspects mentioned in the question.

Therefore, the term that best fits the description of an artificially defined informal geographic area with similar characteristics is "a region."
