This region has a long history of rice cultivation and the domestication of important crops like bananas and coconuts. 2. South America: South America, specifically the Andean region and the Amazon rainforest, is another significant agricultural hearth. The indigenous peoples of South America developed advanced farming techniques, including terrace farming in the Andes and agroforestry systems in the Amazon. 3. Ethiopia: Ethiopia is considered one of the oldest agricultural hearths in Africa. The region has a rich agricultural history, with the domestication of important crops like coffee, teff, and sorghum. Ethiopia's diverse agroecological zones and traditional farming practices have contributed to the development of unique agricultural systems. 4. Northern China: Northern China is known for its long agricultural history and the origin of many staple crops, such as millet, wheat, and soybeans. The region has played a significant role in the development of agricultural technologies, such as irrigation systems and crop rotation. Therefore, considering the historical significance and contributions of Southeast Asia, South America, Ethiopia, and northern China to the development of agriculture, the correct answer is E) all of the above.
