Answer 1

. The scales of analysis in the two maps shown are global and regional. The global map shows the change in rice production per acre of farmland between 1970 and 2015 for the entire world, while the regional map shows the same data for specific regions within the world.B. One agricultural hearth of rice is the Yangtze River Valley in China.C. Intensive agriculture refers to a farming system that aims to maximize the yield from a given piece of land by using a high level of inputs such as fertilizers, pesticides, and irrigation.D. The rice production data for Southeast Asia and West Africa imply that there is a high intensity of land use in these areas. This is because the yields per acre of farmland are relatively high, indicating that a large amount of rice is being produced per unit of land.E. One technological advancement that made the Green Revolution possible was the development of high-yielding varieties (HYVs) of crops. These were genetically modified to produce more grain per acre than traditional crops.F. The data shown on the maps indicate that the Green Revolution had a significant impact on farmers in less developed countries. The increase in rice production per acre of farmland between 1970 and 2015 suggests that farmers in these countries were able to produce more rice due to the use of HYVs and other agricultural technologies. This likely led to an increase in income for farmers and improved food security in these countries.
