Answer: The answer is C: There were massive increases in production due to the use of crops better suited to advance agriculture.
Explanation:
"Green revolution" is a term used for rapid increases in crops especially 'wheat' and 'rice' yields in developing countries which was introduced to Mexico and India by Norman Borlaug and Ms Swaminathan in the early 20th Century. They used improved crop varieties combined with the expanded use of fertilizers and other chemicals to boost crop production in developing countries. The goal of the Green Revolution was to increase the yields of wheat and rice by improving agronomic technology. This helped developing countries to overcome food defects.
