which of the following most accurately describes the green revolution?

The Green Revolution is most accurately described as a dramatic increase in food grain production (especially wheat and rice) in developing countries during the mid‑20th century, made possible by high‑yield crop varieties, chemical fertilizers, pesticides, and expanded irrigation.

Core idea in exam-style terms

If you are choosing from multiple choices, the best option will be the one that says something like:

• “A rapid rise in agricultural output in developing countries due to high‑yielding varieties, chemical inputs, and modern irrigation, beginning in the mid‑1900s.”

Anything that focuses only on “organic farming,” “environmental movement,” or just “more land under cultivation” would be less accurate because the key is technology‑driven yield increases on existing land.

Key features to recognize it

• Use of high‑yielding varieties (HYVs) of wheat and rice.

• Heavy use of chemical fertilizers and pesticides.

• Expansion of irrigation and more mechanization (tractors, pumps, etc.).

• Biggest early impacts in Mexico and India, then spread to other developing countries.

So if one option mentions “high‑yield seeds, fertilizers, irrigation, and big increases in grain output in poor countries after the 1940s,” that is the one that most accurately describes the Green Revolution.
