Question

1. what has been a major factor in the agricultural productivity of the great plains?

a. urbanization

b. industrial development

c. mountainous terrain

d. fertile soil

Explanation:

To determine the major factor in the agricultural productivity of the Great Plains, we analyze each option:

• Option a: Urbanization typically reduces agricultural land and resources, so it is not a major factor for agricultural productivity.
• Option b: Industrial development is more related to manufacturing and industry, not directly to agricultural productivity.
• Option c: The Great Plains is known for its flat terrain, not mountainous terrain. Mountainous terrain is not conducive to large - scale agriculture.
• Option d: The Great Plains has fertile soil (such as the Mollisol soil type), which is a key factor for supporting high agricultural productivity as fertile soil provides essential nutrients for crops.

Answer:

d. Fertile soil
