[B] Intensive subsistence agriculture

[C] Slash and burn agriculture

[D] Nomadic herding

Answer: A
Notes:

Explanation: Commercial grain cultivation is practiced in the interior parts of semi-arid lands of the mid[1]latitudes.

  • Wheat is the principal crop, though other crops like corn, barley, oats and rye are also grown.
  • The size of the farm is very large; therefore entire operations of cultivation from ploughing to harvesting are mechanized.
  • This type of agriculture is best developed in Eurasian steppes, the Canadian and American Prairies, the Pampas of Argentina, the Velds of South Africa, the Australian Downs and the Canterbury Plains of New Zealand.
