B. Chinese river valley
C. Northern plains of India
D. All of the above

Answer 1

Agriculture is an ancient culture and profession followed by many different kinds of tribes and different people from different places. The first crop production was started with rice and wheat. In eastern and southern countries of the world, rice is the main source of food. At the same time in western and northern countries, wheat is the main source of food.

Complete step by step answer: Agriculture which involves the domestication of plants was developed around 11,500 years ago. Wheat appeared about 9,800 years ago. According to historians, rice seems to have appeared around 1400 BC. Wild grains were collected and eaten around 105,000 years ago. However, domestication did not occur until much later. Starting from around 9500 BCE, the eight Neolithic founder crops – emmer wheat, einkorn wheat, hulled barley, peas, lentils, bitter vetch, chickpeas and flax were cultivated in the Levant (Asia). Rye may have been cultivated earlier, but this remains controversial. Rice was domesticated in China by 6200 BCE with the earliest known cultivation from 5700 BCE, followed by mung, soy and azuki beans. Pigs were domesticated in Mesopotamia around 11,000 BCE, followed by sheep between 11,000 BCE and 9000 BCE. Cattle were domesticated from the wild aurochs in the areas of modern Turkey and Pakistan around 8500 BCE. Sugarcane and some root vegetables were domesticated in New Guinea around 7000 BCE. Sorghum was domesticated in the Sahel region of Africa by 3000 BCE. In the Andes of South America, the potato was domesticated between 8000 BCE and 5000 BCE, along with beans, coca, llamas, alpacas and guinea pigs. Bananas were cultivated and hybridized in the same period in Papua New Guinea. In Mesoamerica, wild teosinte was domesticated to maize by 4000 BCE. Cotton was domesticated in Peru by 3600 BCE. Camels were domesticated late, perhaps around 3000 BCE.
Hence, the correct answer is option D.

Note: The first cereal was cultivated is wheat in between 8000-2500 BC. The American farmers first started cultivation in between 5000 - 2500 BC. Squash and chilli were the earliest plants to be grown by the American farmers, and soon it is followed by corn or maize and then by beans and gourds. Vines and olives were first cultivated in between 4000-3500 BC like Grapes.
