Question

read the following passage on the impact of the green revolution. \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 china and india? ∘ they did not have to pay for research, irrigation, or fertilizer. ∘ they no longer needed to fear famine thanks to new high-yield rice varieties. ∘ they could grow new types of food instead of relying on grains like rice. ∘ they were able to do away with ir8 rice and no longer had to fear famine.

Explanation:

1. Analyze Option 1: The passage mentions research, irrigation, and fertilizer led to new rice, but there's no info about not paying for them. Eliminate.
2. Analyze Option 2: The passage says "Research, irrigation, and fertilizer led to a new variety of rice... Since the development... India and China have not feared famine again." This matches as the new rice (IR8) had more grain per plant (high - yield), so they no longer feared famine.
3. Analyze Option 3: The passage is about growing rice (a grain) and other foods, not replacing grains. Eliminate.
4. Analyze Option 4: The passage says IR8 rice helped, not that they did away with it. Eliminate.

Answer:

B. They no longer needed to fear famine thanks to new high - yield rice varieties.
