Difficulty: Very hardSummary: Paraphrasing, Synthesis, and Conciseness

Read the passage below carefully:

While traditional open-air barn storage of harvested yams in central Nigeria exposes crops to humidity-induced rot and pest infestation, resulting in post-harvest losses exceeding forty percent, recent interventions utilizing solar-powered evaporative cooling structures have dramatically altered agricultural economics. These low-cost facilities lower ambient temperatures while maintaining optimal relative humidity, effectively inhibiting sprout development and microbial degradation without relying on synthetic chemical preservatives. Consequently, local farming cooperatives not only preserve tubers for up to eight months but also stabilize off-season market prices, securing higher profit margins. By integrating renewable energy with accessible engineering, smallholder farmers effectively mitigate post-harvest decay and overcome seasonal financial instability.

Which of the following options best synthesizes the core message of the passage into a concise summary statement?

  1. Solar-powered evaporative cooling structures reduce post-harvest yam decay for smallholder farmers, enhancing crop preservation and stabilizing off-season income.Answer
  2. B
    Traditional yam barns in central Nigeria cause over forty percent in post-harvest losses because open-air storage fails to control humidity and pest infestation.
  3. C
    Solar-powered evaporative cooling will completely eliminate the use of synthetic chemical preservatives across all agricultural sectors in Nigeria.
  4. D
    Low-cost evaporative cooling facilities lower relative humidity and increase ambient temperatures to prevent yam sprouting and microbial decay.

Answer

The correct synthesis is that solar-powered evaporative cooling structures reduce post-harvest yam decay for smallholder farmers, enhancing crop preservation and stabilizing off-season income.
The statement highlighting that solar-powered evaporative cooling structures reduce post-harvest yam decay to enhance crop preservation and stabilize income successfully synthesizes both the key technical solution and the ultimate economic outcome. It excludes non-essential supporting figures (such as the forty percent loss statistic or eight-month duration) while retaining all essential thesis components.

Step-by-Step Solution

1
Identify the primary topic and central problem presented in the text.
The text discusses traditional yam storage causing high post-harvest losses due to rot and pests.
Establishing the baseline problem clarifies what essential issue the main thesis addresses.
2
Identify the main intervention/solution introduced by the author.
Solar-powered evaporative cooling structures lower temperature and maintain humidity without chemical preservatives.
The intervention represents the core mechanism of the passage.
3
Identify the ultimate outcome/impact of this intervention.
Farmers preserve yams up to eight months, stabilize market prices, and increase profit margins.
Synthesizing requires linking the technological cause to its major socio-economic effect.
4
Evaluate options for conciseness, accuracy, and essential coverage while discarding minor details.
The option stating that solar cooling reduces decay while enhancing preservation and income captures the central argument concisely.
A summary must combine cause and effect into a clear statement while omitting illustrative statistics and minor technical specifications.
