Zorluk: ZorPassage Assumptions and Underlying Premises

Read the passage carefully and answer the question that follows:

To mitigate agricultural distress caused by volatile diesel fuel prices and erratic electricity supply, several state governments have launched capital subsidy schemes for smallholder farming cooperatives to install solar-powered mini-grids dedicated to micro-irrigation. Policy advocates argue that by transitioning from diesel pump sets to collective solar infrastructure, rural cooperatives will lower operational expenditures and expand crop cultivation into dry seasons, thereby enhancing agrarian household incomes. While critics warn that zero marginal pumping costs could accelerate groundwater depletion, state authorities maintain that solar mini-grids represent the most effective strategy to achieve immediate carbon emissions reduction in the farm sector while preserving agricultural output. This intervention hinges on the premise that decarbonizing irrigation infrastructure directly translates into sustainable rural economic growth.

Which one of the following expresses the most crucial underlying assumption on which the argument regarding the carbon reduction effectiveness of solar mini-grid subsidies rests?

  1. A
    Groundwater depletion poses an uncontrollable threat that renders all subsidized renewable energy projects in agriculture entirely counterproductive.
  2. B
    Solar-powered micro-irrigation systems eliminate the marginal energy cost of pumping water for agricultural cooperatives.
  3. The solar mini-grids installed by farming cooperatives will primarily substitute existing fossil-fuel-driven irrigation methods rather than merely supplementing them.Cevap
  4. D
    Solar panel manufacturing and battery disposal generate secondary environmental impacts that outweigh rural carbon savings.

Cevap

The argument fundamentally assumes that solar mini-grids installed by farming cooperatives will primarily substitute existing fossil-fuel-driven irrigation methods rather than merely supplementing them.
The correct response identifies the critical unstated premise. For the state authorities' argument—that solar mini-grids achieve immediate farm-sector carbon reduction—to hold true, the new solar capacity must actually replace fossil-fuel (diesel) consumption. If farmers merely use solar energy in addition to running their existing diesel pump sets at full capacity, total emissions will not drop. Therefore, substitution rather than mere addition is a logically necessary assumption.

Adım Adım Çözüm

1
Identify the central argument and conclusion
The core claim is that transitioning smallholder cooperatives to solar mini-grids will achieve immediate carbon emissions reduction in the agricultural sector while maintaining productivity.
Understanding the main thesis is required before identifying the unstated premise that supports it.
2
Isolate the gap between stated premises and the conclusion
The author assumes that installing solar capacity automatically results in reduced fossil fuel usage and carbon emissions.
An assumption is an unstated bridge linking the intervention (solar mini-grids) to the claimed outcome (net carbon reduction).
3
Apply the Negation Test to validate the underlying assumption
If the solar grids only supplement energy consumption while diesel pumps continue operating at full capacity, no carbon reduction occurs, causing the central argument to collapse.
A statement whose negation breaks the conclusion is a logically required assumption.
