Question

based on source 10, which was a way that land cultivation led to growth of cities?
○ volcanic rock became used in all agricultural settlements
○ fewer farmers were needed to supply food to more people
○ it forced hundreds of thousands of people to crowd into cities
○ crops, such as corn and beans, began to be used as currency

Explanation:

To determine how land cultivation led to city growth, we analyze each option:

• "Volcanic rock became used in all agricultural settlements": Using volcanic rock in settlements doesn't directly relate to city growth from land cultivation.
• "Fewer farmers were needed to supply food to more people": While this is a result of agricultural advancement, it doesn't directly explain city growth.
• "It forced hundreds of thousands of people to crowd into cities": Land cultivation (agriculture) led to a surplus, allowing people to specialize in non - agricultural jobs, and the need for people to live close together for trade, governance, etc., forced people into cities, directly relating to city growth.
• "Crops, such as corn and beans, began to be used as currency": Using crops as currency is about economic exchange, not city growth from land cultivation.

Answer:

It forced hundreds of thousands of people to crowd into cities
