What is produced mainly in the Great Plains region?

• A. Rice
• B. Corn
• C. Wheat
• D. Tomatoes

Answer: (C)

The question tests how climate and soil shape the crops a region can produce. The Great Plains are a vast expanse of flat grassland with fertile soils and a semi-arid to temperate climate that suits grain crops, especially wheat. Wheat, including winter and spring varieties, thrives with the cool winters and relatively dry summers typical of the region, and it adapts well to large-scale farming on the prairie soils. That combination makes wheat the main crop produced there.

Rice would require a lot of water and warm, very humid conditions not characteristic of the Great Plains. Tomatoes need a longer, warmer growing season and reliable heat, which isn’t the defining climate of this region. Corn is grown in other parts of the country and is important, but the Great Plains are most strongly associated with wheat production, making it the best answer.
