Read the passage below carefully and answer the question that follows:
Along the shores of Lake Victoria, smallholder fish farmers have long grappled with post-harvest losses caused by inadequate refrigeration infrastructure and unreliable municipal power grids. Traditionally, fishermen were forced to sell their daily catch immediately to middle agents at severely depressed prices to prevent spoilage. Recently, community-managed solar-powered cold storage hubs have emerged across coastal landing sites, fundamentally altering this economic dynamic. These off-grid units utilize high-efficiency photovoltaic panels paired with thermal ice-battery storage to maintain sub-zero temperatures throughout the night without grid reliance. By extending the shelf life of tilapia and Nile perch from hours to several days, fishermen can now aggregate their yields and negotiate directly with urban wholesale distributors. Preliminary economic surveys indicate that participating cooperatives have seen net household incomes rise by over thirty percent within their first year of operation. Furthermore, the reduction in spoiled fish discarded along the shoreline has yielded tangible sanitation benefits for local fishing villages.
Which of the following statements best expresses the main idea of the passage?
- The adoption of community-managed solar cold storage hubs has improved the economic livelihoods of fish farmers by mitigating post-harvest losses.Cevap
- BOff-grid refrigeration units utilize thermal ice-battery storage to maintain sub-zero temperatures overnight without grid reliance.
- CGovernment subsidies for photovoltaic panels have successfully eliminated rural poverty across East African fishing communities.
- DLocal fishermen prefer selling their daily catch to middle agents because urban wholesale distributors demand lower prices.
