Which of the following statements is true based on the passage's discussion?

• A. Leisure time increased with the rise of agriculture
• B. Crops were the sole determining factor in mound construction
• C. Access to agricultural resources varied regionally
• D. Mound builders had little interaction with other cultures

Answer: (C)

The statement about access to agricultural resources varying regionally is accurate because, in discussions about agriculture, it often highlights how different geographical areas impacted the availability and type of resources such as water, soil quality, and climate conditions. These variations would have influenced agricultural practices and, consequently, the capabilities of communities to build mounds.

In agricultural societies, the availability of crops and resources is not uniformly distributed. This regional variation would significantly affect the development of societies, including their architectural and agricultural practices. It's important to consider how these factors can lead to differences in economic prosperity, cultural exchange, and community development.

The other options, while they may represent ideas that could be applicable in a general sense, do not align with the passage’s specific focus. This makes them less suitable as correct statements based on the passage’s discussion.
