Zorluk: OrtaPassage Assumptions and Underlying Premises

Read the following passage carefully:

In remote high-altitude watersheds, traditional power grid extensions by central utility enterprises remain financially unviable due to rugged terrain and low population density. To address persistent rural energy poverty, state development agencies have recently subsidized community-owned micro-hydro generation units. These decentralized units enable mountain villages to power local agro-processing machinery, such as grain mills and cold-press oil expellers, thereby significantly reducing post-harvest crop losses and eliminating costly transport to lowland commercial processing hubs. Policy analysts argue that by granting village cooperatives complete operational management and revenue retention from local electricity tariffs, these micro-hydro installations will achieve long-term financial self-sustainability without requiring ongoing state operational grants. Consequently, state administrators are positioning this community-managed model as a primary scalable blueprint for sustainable rural industrialization across alpine regions.

Which one of the following expresses the most crucial assumption on which the policy analysts' conclusion regarding financial self-sustainability rests?

  1. A
    Community-owned micro-hydro units reduce expenses for mountain farmers by eliminating the need to transport raw harvests to lowland processing hubs.
  2. The revenue generated from local electricity tariffs will be sufficient to cover the recurring maintenance and operational costs of the micro-hydro installations.Cevap
  3. C
    Centralized power grid extensions are inherently incapable of ever delivering reliable electricity to any rural agricultural region.
  4. D
    High-altitude streams experience severe seasonal variations in water flow that impair hydroelectric output during dry winter periods.

Cevap

The revenue generated from local electricity tariffs will be sufficient to cover the recurring maintenance and operational costs of the micro-hydro installations.
The policy analysts conclude that community-managed micro-hydro units will achieve long-term financial self-sustainability without ongoing state grants because cooperatives retain revenue from local electricity tariffs. For this argument to hold, it must be assumed that the revenue from these tariffs will be adequate to cover all ongoing operational and maintenance expenses. Applying the negation test, if tariff revenues are insufficient to cover maintenance, the micro-hydro units would inevitably collapse or require continuous state grant support, directly invalidating the analysts' conclusion.

Adım Adım Çözüm

1
Identify the main conclusion of the policy analysts.
The conclusion is that community-owned micro-hydro installations will achieve long-term financial self-sustainability without requiring ongoing state operational grants.
Assumptions are unstated premises necessary to logically bridge stated premises to the final conclusion.
2
Identify the explicit premise given for achieving self-sustainability.
The author cites village cooperatives having complete operational control and retaining revenue from local electricity tariffs.
The argument assumes tariff revenue retention guarantees independence from state grants.
3
Apply the negation test to candidate assumptions.
If local tariffs are insufficient to cover ongoing maintenance and operational costs, the units cannot survive without continuous state operational grants. Thus, the argument fails if this premise is false.
A claim is a necessary assumption if its negation undermines the author's conclusion.
