Many countries reaped the benefits of the green revolution. India and China, for example, were threatened with famine due to their growing populations. Research, irrigation, and fertilizer led to a new variety of rice called IR8, which produced more grain per plant. Since the development of IR8 rice and other foods, India and China have not feared famine again. In fact, many Asian countries now grow rice, and India is a leading producer and exporter. According to the passage, what were the benefits of the green revolution for such countries as China and India? It helped improve research and irrigation, which led to new types of rice. Countries no longer needed to fear famine thanks to new high-yield rice varieties. Countries grew new types of food instead of relying only on grains, such as rice. It helped countries prevent and slow the growth of their populations.
