Which statement best describes grain farming in temperate zones?

• A. It is mostly rain-fed with no irrigation
• B. It exists mainly in tropical regions
• C. It is dominated by livestock
• D. It often dominates large-scale production in the Great Plains, Eastern Europe, and parts of Asia

Answer: (D)

Grain farming in temperate zones is defined by large-scale, mechanized production of cereal crops in expansive plains. This pattern is exemplified by the Great Plains, Eastern Europe, and parts of Asia, where vast areas are devoted to growing wheat, barley, and other grains for widely sold markets. The emphasis is on the scale and geographic concentration of crop production, rather than livestock or tropical conditions. Irrigation varies by region—some areas rely on rainfall while others use irrigation—but the defining feature is how production is organized and distributed across major temperate plains.
