Question

what happened as cities grew larger? people stopped having children cities expanded beyond urban centers people grew sickly and died

Explanation:

To answer this, we analyze each option:

• "people stopped having children" is incorrect as city growth doesn't mean people stop having children.
• "cities expanded beyond urban centers" is correct. As cities grow larger, they often expand into surrounding areas, beyond their original urban centers (like forming suburbs).
• "people grew sickly and died" is incorrect. While historical urban areas had health issues, the general process of city growth isn't defined by people getting sick and dying; cities grow due to migration, economic opportunities, etc., and modern city growth has better health management.

Answer:

B. cities expanded beyond urban centers (assuming the second option is labeled B; adjust label based on actual numbering, but the content is "cities expanded beyond urban centers")
