Difficulty: HardSummary: Paraphrasing, Synthesis, and Conciseness

Read the passage below carefully:

"For decades, artisanal salt miners along the coastal lagoons of Akwa Ibom relied on wood-fueled evaporation pits to process brine, a method that caused severe local mangrove deforestation and yielded discolored, low-grade salt. Recognizing the ecological and financial toll, a sustainable development initiative introduced elevated solar evaporation pans coupled with sand-filtration units. The filtration process removes organic sediment prior to evaporation, producing high-purity white salt while entirely eliminating the need for firewood. As a result, coastal communities have successfully preserved critical mangrove ecosystems while earning higher profit margins through refined salt sales."

Based on the passage, arrange the synthesized summary statements in their correct logical sequence, tracing the progression from the background problem to the final outcome.

  1. 1Artisanal wood-fueled salt processing caused severe mangrove deforestation and yielded discolored salt.
  2. 2A sustainable initiative introduced elevated solar evaporation pans combined with sand-filtration units.
  3. 3Filtration removed impurities prior to solar evaporation, producing high-purity salt without firewood.
  4. 4Coastal communities achieved mangrove conservation alongside increased earnings from refined salt sales.

Answer

The correct logical sequence places the traditional baseline problem first, followed by the introduction of the technological intervention, the operational mechanism, and finally the overarching ecological and economic synthesis.
The correct sequence follows the passage's logical structure: establishing the baseline environmental and quality crisis of traditional salt mining, introducing the sustainable solar-filtration intervention, explaining how the process removes impurities without fuel, and concluding with the synthesized dual benefits of ecological conservation and economic gain.

Step-by-Step Solution

1
Identify the initial baseline situation and problem in the passage.
The passage starts by describing traditional wood-fueled brine evaporation and its negative consequences (deforestation and low-grade salt).
A coherent summary sequence must establish the initial context or issue before explaining solutions.
2
Identify the intervention or new method introduced.
The text describes the introduction of solar evaporation pans and sand-filtration units by a development initiative.
The introduction of a solution logically follows the problem statement.
3
Determine how the intervention operates to solve the core issue.
The text explains that sand-filtration eliminates sediment prior to evaporation, creating clean salt without requiring firewood.
Explaining the mechanism connects the new infrastructure to its practical results.
4
Identify the final synthesized outcome or broader impact.
The passage concludes by highlighting dual benefits: mangrove ecosystem conservation and enhanced profit margins.
Synthesized summary conclusions belong at the end of the logical sequence.
