Difficulty: Medium
Correct Answer: I and II are strong
Explanation:
Introduction / Context:
Groundwater-policy design balances immediate agricultural needs with long-term aquifer sustainability. India’s agrarian regions often depend on wells and tube-wells; over-extraction risks salinity, depletion, and ecosystem damage.
Given Data / Assumptions:
Concept / Approach:
Strong arguments focus on core objectives and evidence: ensuring food security (I) and preventing environmental collapse (II). An appeal to authority (III) is weaker unless tied to domestic data and actionable mechanisms.
Step-by-Step Solution:
1) I is strong because groundwater supports cropping where surface irrigation is limited; abrupt limits could hurt production if not sequenced with alternatives (micro-irrigation, crop shifts, canal rehab).2) II is strong due to clear sustainability risks—falling tables, energy-inefficient pumping, and long-run productivity loss—justifying caps, pricing, or permits in stressed blocks.3) III is weak as framed: international cautions matter, but strength derives from domestic hydrology and policy design rather than external warnings alone.
Verification / Alternative check:
Effective regimes pair limits with support: water-efficient tech (drip/sprinkler), crop diversification, real-time monitoring, and power pricing reforms.
Why Other Options Are Wrong:
“II and III/All/Only II/I and III” misweight an authority appeal (III) over substantive local evidence.
Common Pitfalls:
Adopting blanket bans without transition supports; ignoring basin-level variability.
Final Answer:
I and II are strong.
