Question

the united states is divided into blank.
which best completes the sentence?

○ political territories
○ transportation routes
○ geographic regions
○ watershed areas

Explanation:

To determine the best completion, we analyze each option:

• "Political territories" usually refer to states, districts, etc., but the US is commonly divided into geographic regions (like Northeast, Midwest, etc.) for geographic analysis.
• "Transportation routes" are for travel/transport, not a primary division of the country.
• "Geographic regions" is correct as the US is often categorized into regions (e.g., West, South) based on geography, climate, culture, etc.
• "Watershed areas" relate to drainage basins, not a general division of the US.

Answer:

geographic regions (corresponding to the option "geographic regions")
