Question Statement:
Read the passage: 'The green revolution succeeded in staving off widespread famine by introducing high-yielding dwarf varieties of wheat and rice responsive to synthetic fertilizers and canal irrigation. However, this intensive monoculture has extracted a heavy ecological toll: groundwater depletion in alluvial plains, soil micronutrient exhaustion, and genetic erosion of indigenous landraces. Modern agronomy must therefore transition from input-intensive productivity towards ecological resilience.' What is the author's primary assertion?
Options:
- (A) The historic gains of the green revolution must now be balanced with a transition to ecologically resilient practices.
- (B) High-yielding dwarf varieties should be completely abandoned immediately.
- (C) The green revolution failed to achieve any increase in grain production.
- (D) Indigenous landraces required higher chemical fertilizer doses than dwarf cultivars.
