Read the passage below carefully and answer the question that follows.

Across agrarian communities in North-Central Nigeria, post-harvest losses of perishable crops like tomatoes and cassava have historically eroded farmer incomes by up to forty percent. The recent deployment of off-grid solar-powered cold storage units and processing hubs is dramatically reversing this trend. By offering affordable, clean refrigeration right at rural farm-gate markets, these solar mini-grids enable smallholder cooperatives to preserve harvested produce for weeks rather than selling immediately at distress prices. Consequently, rural households have recorded an average thirty percent increase in net seasonal revenue. Although high initial capital expenditure for lithium-ion battery banks remains a financial hurdle for private developers, the primary catalyst behind the region's agricultural stabilization is the reduction of post-harvest spoilage achieved through localized renewable cooling technology. Ancillary benefits such as nighttime street lighting and mobile phone charging points in nearby villages have also improved local night commerce, though these amenities contribute minimally to the core economic stabilization of the agricultural sector.

Which of the following options best captures the essential argument of the passage while excluding supporting details and secondary benefits?

  1. A
    High capital costs of lithium-ion batteries have completely prevented smallholder cooperatives from preserving harvested cassava.
  2. The introduction of localized solar refrigeration has stabilized rural farm incomes primarily by minimizing post-harvest crop loss.Cevap
  3. C
    Nighttime street lighting and mobile phone charging hubs powered by solar mini-grids have revitalized night commerce in rural villages.
  4. D
    Private developers will soon eliminate all agricultural poverty across West Africa by replacing fossil fuels with lithium-ion technology.

Cevap

The essential argument of the passage is that the introduction of localized solar refrigeration has stabilized rural farm incomes primarily by minimizing post-harvest crop loss.
The correct answer accurately states the main thesis of the passage: off-grid solar refrigeration stabilizes rural agricultural incomes by curbing post-harvest crop spoilage. It focuses strictly on the principal cause-and-effect relationship without incorporating minor side benefits or illustrative figures.

Adım Adım Çözüm

1
Analyze the passage structure and distinguish the core problem from the primary solution.
Identified the problem (post-harvest crop spoilage reducing farm incomes) and the primary intervention (solar-powered cold storage units).
Separating the central thesis from supporting elaboration is necessary to identify the core message.
2
Filter out supporting details, obstacles, and ancillary (secondary) benefits.
Recognized that 40% loss metrics, 30% revenue increases, battery cost hurdles, and village street lighting are supporting evidence, obstacles, or side benefits.
A concise summary must exclude illustrative metrics, side effects, and minor details.
3
Synthesize the core cause-and-effect relationship into a single central statement.
Localized solar cooling reduces spoilage, which serves as the principal catalyst for stabilizing farm revenues.
Matching the synthesized core statement to the correct answer choice confirms mastery of summary distillation.
