“During the late 1960s, the introduction of high-yielding 'miracle rice' (IR8) in India and the Philippines dramatically increased crop yields. However, these new crop varieties required intensive applications of synthetic fertilizers, chemical pesticides, and heavy irrigation to achieve their potential. Without this combination of chemical inputs and modern water management, the new crops would produce lower yields than traditional varieties.”
—Adapted from agricultural reports on the Green Revolution in Asia, 1971
Based on the passage, which of the following best describes the primary method by which the Green Revolution increased agricultural yields in Asia?
- By developing high-yielding crop varieties that relied on chemical inputs and irrigation systems.Answer
- BBy implementing organic farming methods and promoting environmental conservation.
- CBy replacing steam-powered machinery with electrical harvesting equipment.
- DBy establishing new maritime trade routes to exchange indigenous crops between the Eastern and Western hemispheres.
Answer
The Green Revolution increased agricultural yields by developing high-yielding crop varieties that relied on chemical inputs and irrigation systems.
The correct option is supported by the text's explanation that the Green Revolution's success depended on the pairing of new seed varieties (like IR8) with synthetic fertilizers, pesticides, and irrigation systems.
