Read the following passage carefully:

The contemporary transition toward technology-intensive groundwater management, particularly through state-subsidized micro-irrigation systems, is frequently promoted in policy circles as a definitive solution to agricultural water scarcity. However, empirical hydrological assessments reveal a systemic paradox: while micro-irrigation technologies undoubtedly increase field-level crop water efficiency, they rarely result in net water savings at the aggregate river basin level. State subsidy frameworks that decouple equipment adoption from strict volumetric groundwater extraction limits inadvertently incentivize agricultural intensification. Empowered by enhanced input efficiency per hectare and lowered operational costs, farming enterprises frequently expand their net cultivated land area or transition toward higher-value, water-intensive cash crops. Consequently, technological modernization pursued in an administrative vacuum magnifies total aquifer depletion rather than mitigating it. Without institutional mechanisms to govern resource demand, supply-side efficiency measures merely transform technological efficiency into increased environmental pressure. To establish genuine hydrological sustainability, public policy must transcend the narrow focus on technology dissemination. Effective groundwater governance necessitates integrating financial subsidies within decentralized, community-monitored water budgeting frameworks, enforcing rigorous volumetric extraction caps, and aligning crop planning incentives with regional ecological carrying capacities.

Based on the passage above, which of the following statements correctly capture the author's central argument regarding groundwater governance?

  1. Promoting irrigation efficiency without regulatory extraction caps can counterproductively increase total groundwater depletion through crop intensification.Cevap
  2. B
    Micro-irrigation equipment fails to provide any measurable improvement in water productivity even at the individual plot level.
  3. Achieving sustainable resource governance requires linking financial subsidies to community-based water budgeting and ecological limits.Cevap
  4. D
    Subsidies for agricultural machinery should be completely abolished by central administrative authorities to prevent environmental degradation.

Cevap

The central argument of the passage is captured by the statements highlighting that promoting irrigation efficiency without extraction caps can inadvertently increase total groundwater depletion through crop intensification, and that achieving sustainable governance requires linking financial subsidies to community-based water budgeting and ecological limits.
The passage focuses on the paradox of micro-irrigation: while field-level efficiency increases, aggregate water consumption often rises because subsidy frameworks lack extraction caps. To solve this, the author advocates reforming governance by embedding subsidies within community water budgets and ecological limits. Thus, the two correct statements together encapsulate both the central problem identified by the author and the proposed governance framework.

Adım Adım Çözüm

1
Analyze the passage structure and identify the primary thesis.
The author contrasts field-level efficiency gains of micro-irrigation with basin-level depletion caused by unconstrained agricultural expansion, concluding that technology must be coupled with extraction caps and water budgeting.
Identifying the overarching thesis distinguishes core concepts from specific details or false inferences.
2
Evaluate statement accuracy against the identified thesis.
Statements concerning the risks of unconstrained efficiency promotion and the necessity of linking subsidies to community water budgeting directly mirror the central thesis.
Selecting statements that jointly reflect the author's primary recommendations and argument.
3
Eliminate options that misrepresent passage facts or introduce unstated external assertions.
The statement claiming zero efficiency at the plot level contradicts explicit text, while the statement advocating total abolition of subsidies introduces extreme external assumptions.
Distractors often rely on detail inversion or extreme real-world policy extrapolations.

Anahtar Kavram

Identifying the central message requires distinguishing the author's core thesis—that technological solutions require structural demand management—from secondary details and unstated external claims.
