Read the passage below carefully and answer the question that follows.
Across rural Sub-Saharan Africa, post-harvest crop loss presents a formidable barrier to food security and smallholder profitability, with up to forty percent of perishable produce spoiling before reaching urban markets. Traditional preservation methods, such as open-air sun drying and smoking, often fail to protect high-moisture vegetables and dairy products from bacterial contamination and ambient humidity. In response to this challenge, off-grid solar-powered cold storage units have emerged as a transformative intervention. By utilizing photovoltaic arrays coupled with thermal energy storage technology, these decentralized refrigeration systems maintain optimal temperature ranges without relying on unstable municipal power grids. Consequently, local farming cooperatives can store harvested yields for extended periods, reducing immediate distress sales and mitigating seasonal market gluts. Although high initial capital expenditure remains a constraint for widespread adoption, communal leasing frameworks are rapidly expanding access. Ultimately, localized cold-chain infrastructure is reshaping agricultural supply chains by stabilizing rural incomes and safeguarding nutritional security.
Which of the following statements best captures the main idea of the passage?
- Solar-powered cold storage offers a transformative solution to post-harvest crop loss by enhancing preservation and stabilizing rural agricultural economies.Cevap
- BTraditional preservation techniques like smoking and sun drying fail to protect perishable crops from humidity and bacteria.
- CForty percent of perishable produce in Sub-Saharan Africa spoils due to complete reliance on municipal power grids.
- DHigh capital expenditure has prevented smallholder farmers from accessing decentralized cold-chain infrastructure.
